AD-X2 Controversy The AD-X2 battery-testing controversy, which began in 1948, was caused by the testing of a material - a battery additive - marketed under the name Battery AD-X2.” This product when added to a lead-acid battery allegedly improved its performance and, under some circumstances, could presumably revive a dead battery. This incident resulted in congressional hearings, newspaper headlines, and charges of Bureau bias against the little guy.

Aeronautic Instruments This collection depicts the instruments developed by the aeronautic instruments program at the National Bureau of Standards (NBS). Included are photographs of altimeters, airspeed indicators, tachometers, and other aeronautical instruments.

Airplane Detection Apparatus During WW I, Hiram B. Ely, at the U.S. Army’s Franklin Arsenal in Philadelphia, led the development of an acoustic device to detect and track the location of aircraft. The device was tested at the Aberdeen Proving Ground in Maryland.
Airplane Research World War I Except for the pioneer work of the Wright brothers, and a few others, serious study of the scientific fundamentals of flight began in this country only after the National Advisory Committee for Aeronautics (NACA) requested National Bureau of Standards (NBS) undertake an investigation of aviation aerodynamics in 1915. NBS was to play an important part in this research before the NACA acquired facilities of its own.
Alaska Pipeline Beginning in 1973, researchers from the National Bureau of Standards and the National Oceanic and Atmospheric Administration conducted a three-and-a-half-year study to determine natural levels of hydrocarbons in the Alaskan marine environment prior to the opening of the Trans-Alaska oil pipeline.

Anechoic Chamber The Sound Building, dedicated to the study of acoustic phenomena, featured a large anechoic chamber. It was begun in 1965 and occupied early in 1968. It achieved its quiet because it was lined with large fiberglass wedges paired in a pattern that absorbed more than 99% of the sound originating within it. The chamber was used for microphone calibrations, loudspeaker measurements, sound level meter calibration, noise measurement, psychoacoustic experiments, radiation and scattering experiments, and general use when a quiet environment was needed.

Aneroid Tachometers The first actual war-research agency of World War I was the National Advisory Committee for Aeronautics (NACA), established by Congress in March 1915 to initiate and direct scientific studies in problems of flight. The Bureau of Standards, represented on the Committee by Dr. Stratton, was asked to begin investigations at once of the physical factors in aeronautic design. Many of the aviation problems subsequently assigned by NACA to the Navy and War Departments were, since they lacked research facilities, turned over to the Bureau as it "became the scientific laboratory for the two military services." All of the altimeters, airspeed indicators, tachometers, and other aeronautical instruments that came to the Bureau for examination and testing were based on European prototypes. Many were still in an elementary stage and underwent considerable modification in the laboratories prior to their adoption as standard by the U.S. Army and Navy [From Measures for Progress, by Rexmond Cochrane, pp. 159-160, 181.]

Appliance Efficiency This collection consists of images documenting the testing of household appliances at the National Bureau of Standards (NBS). Items tested included ranges, laundry appliances, and water heaters. NBS developed test procedures to calculate household appliance efficiency and operating costs to help the Federal Energy Administration (FEA) meet its responsibilities under the Energy Policy and Conservation Act (1975).

Atomic Clock This collection is comprised of images documenting the development of the atomic clocks that were part of the National Bureau of Standards (NBS) Atomic Time System. The NBS atomic clock program sought to provide a spectroscopic standard capable of being used as a new atomic standard of time and frequency to replace the mean solar day and so change the arbitrary units of time to atomic ones.

Automated Manufacturing Research Facility In 1979 National Bureau of Standards (NBS) scientists realized the significance to American industry of a factory in which every part could be made automatically, with no rejects and little scrap; thus was born the idea for an Automated Manufacturing Research Laboratory (AMRF). The concept had several components: careful analysis of the manufacturing process to reduce errors in materials treatment to acceptable levels; generation of manufacturing protocols involving robotics and humans within a generic system; and development of interfacing methods to permit the use of optimum efficiency in the choice of equipment, control computers, and software.

Automobile Research This collection documents the research at the National Bureau of Standards (NBS) on automobiles in the first half of the twentieth century. Between 1920 and 1930 the number of cars registered in the United States leaped from 9 to 26.5 million. NBS research on the automobile and airplane began as an effort to conserve the Nation's supply of gasoline and oil.

 

Award Winners High quality work by National Bureau of Standards (NBS)/ National Institute of Standards and Technology (NIST) staff is recognized every year by awards from outside groups, from the Federal government, and from the NBS/NIST itself. Images include 1992 R&D 100 entry forms accompanied by photographs of product and principal developers.

 
Baseball Experiment - Lyman Briggs In 1959 National Bureau of Standards director emeritus Dr. Lyman Briggs was in his 85th year when he determined to settle a long-disputed phenomenon: scientific proof of the degree a baseball can be made to curve in the 60-foot throw from the pitcher's box to the plate. These are images from that research. Dr. Briggs used his knowledge of aerodynamics to test what at the time was considered by some to be a myth. Does a pitched “curveball” in the sport of baseball really curve?
Biosensors National Institute of Standards and Technology studied the optical characteristics of fluorescent molecules as part of its research on biosensors.
Blind Landing of Aircraft In 1930 Harry Diamond of the National Bureau of Standards led the development of radio equipment for airplanes that, when paired with the runway radio range beacon system he had developed earlier, made possible the first blind landing of an airplane entirely by radio guidance.
Building and Fire Research This collection documents work that began with funds appropriated by Congress in 1913 so that the National Bureau of Standards (NBS) could study fire resistant building materials. Fires were claiming thousands of lives annually in the U.S., with property losses exceeding $250 million. In a joint undertaking with the National Fire Protection Association and the Underwriters' Laboratories, NBS aimed at a thorough study of the behavior and safety of building materials in various types of construction under all possible fire conditions.

Building Codes Research In the 1930s the National Bureau of Standards studied the properties of building materials to encourage the adoption of building standards to improve overall construction quality and workmanship, and for the simplification and standardization of building materials and dimensional varieties in order to reduce costs. Included in this category are images of a Noisemeter, and Plumbing Code Research.

Building Structural Testing The National Bureau of Standards expanded its research on structural materials by installing new mammoth testing machines and a special building to house them. These included a 1-million-pound crushing machine for compression tests of brick, stone, cement, and concretes; and a specially designed 2,300,000-pound Emery universal testing machine, for breakdown and exhaustion tests of girders and other large structural members.
Camera for Photographing Eclipse In the late 1930s the National Geographic Society and the National Bureau of Standards jointly sponsored an expedition to the Kazak region of the U.S.S.R. to observe and study a solar eclipse. For this expedition NBS optical physicist Irvine C. Gardner designed a 4.2-meter eclipse camera with a 22-centimeter astrographic lens.
Capitol (U.S.) Dome Exterior In the early 2000s National Institute of Standards and Technology investigated the composition and properties of the cast iron and wrought iron that form the dome of the U. S. Capitol building in Washington, D.C. The research was used to determine the dome's condition, and to predict how the outer shell might respond to weld repair of cracks.

Cement Testing In 1911 the cement laboratories of the Bureau National Bureau of Standards (NBS) began testing cement purchased for Government construction projects. The sampling required over 500,000 physical tests for fineness, specific gravity, tensile strength, and time of setting. These tests, however, did little more than determine whether the samples met current Government specifications, and in many cases the specifications were far from clear or consistent. Early in 1912, NBS called manufacturers and Federal engineers to the first Portland Cement Conference, in order to consider preparation of a single standard specification. As a result, a Presidential Executive order was issued on April 30, 1912, declaring that all Portland cement purchased by the Government was to conform to the specification agreed upon.

Ceramics This collection contains photos of early ceramics research carried out at the National Bureau of Standards. With the U.S. entry into World War I, the Bureau became involved in redesigning the shortcomings in the Allies’ new high-powered planes. Before the war ended the Bureau’s electrical and ceramic divisions had devised a much-improved arrangement of engine circuits and produced a better type of porcelain for aviation spark plugs and the liners of rocket motors. By 1939, the Bureau was involved in work on porcelain-coated metals. Various items were placed in service in homes and their performance was compared with that predicted by laboratory tests.

Charters of Freedom At the request of the Librarian of Congress in 1939, an investigation was undertaken by the National Bureau of Standards (NBS) to determine the best means of preserving the original copies of the Declaration of Independence and the Constitution of the United States. On March 16, 1940, NBS recommended that the documents be placed in specially-constructed enclosures, that the air in the enclosures be replaced with a chemically inert gas, and that the enclosures be sealed. This project was interrupted by World War II and in 1945 the work resumed. The enclosures were designed with detectors to make sure air could not leak into them and with filters to protect the documents against radiation. An external lighting system was created to provide adequate light to view the documents.

Colorimetry Colorimetry is the science behind the measurement of color. A variety of industries and interest groups pushed the National Bureau of Standards (NBS) to standardize color at the beginning of the 20th Century. As early as 1912, to settle disputes at the time, a cottonseed oil firm and representatives of the butter and oleomargarine industries called on NBS for help with color grading of their products. This research opened up a whole new branch of physics for investigation.

Commercial Standards Images in this collection reflect the efforts of the National Bureau of Standards (NBS) to achieve standards for industry after World War I. Long advocated by the NBS, "the crusade for commercial standardization," became a three-pronged attack on waste in commerce and industry. It comprised standardization of business practices and of materials, machinery, and products; specifications to insure good quality of products; and simplification in variety of products. The culmination of the standardization program came in 1927 when then Department of Commerce Secretary Herbert Hoover established the division of trade standards at the NBS. Its purpose was to consolidate Bureau activities relating to standards, extend to the commercial specification field the cooperative methods of simplified practice, and make more readily available to industry the results of the Federal Specifications Board. Where specifications formulated by industry up to that time had principally served the needs of individual industries, the commercial standards published by the trade standards division were to be specifications with industry-wide application.

Compasses, Inclinometers, and Thermometers During WWI, many of the aviation problems assigned by the National Advisory Committee for Aeronautics (NACA) to the Navy and War Departments were, since they lacked research facilities, turned over to the Bureau as it became the scientific laboratory for the two military services. All of the altimeters, airspeed indicators, tachometers, and other aeronautical instruments that came to the Bureau for examination and testing were based on European prototypes. Many were still in an elementary stage and underwent considerable modification in the laboratories prior to their adoption as standard by the U.S. Army and Navy [From Measures for Progress by Rexmond Cochrane, pp. 159-160, 181.] In the early 1900s, the Bureau's Heat and Thermometry section acquired thermometers from France and Germany as working standards. The Bureau was therefore prepared to certify almost any precision thermometer used in scientific work, most low-temperature engineering and industrial thermometers, and all ordinary commercial thermometers.

Computer Security This collection contains images of the National Institute of Standards and Technology’s (NIST) early work in computer security. Instructed by the Computer Security Act of 1987 to receive and review Federal security plans for unclassified but sensitive information, NIST and the National Security Agency immediately initiated the Computer Security and Privacy Plans (CSPP) review project. The team found considerable uncertainty among the agencies regarding the most effective means to provide for secure computer operations; thus, team recommendations focused on education.

Constant of Gravitation This collection contains photographs of the scales and other instruments used for the determination of the constant of gravitation at the National Bureau of Standards between 1924 and 1942. Paul R. Heyl of the Mechanics and Sound Division made his first redetermination of the constant of gravitation (G) in 1930. In 1942, Heyl and Peter Chrzanowski published the results of a new determination of the constant of gravitation made with an improved torsion balance. Only slight improvement in precision over the 1930 result was achieved.

Cryogenics The National Bureau of Standards’ (NBS) interest in cryogenics (the production of very low temperatures and the properties of materials at those temperatures) dates back to 1904, when a plant for making and maintaining liquid and solid hydrogen, the invention of British physicist James Dewar, was exhibited at the St. Louis Fair in 1903 and purchased by NBS. The images in this collection document experiments and equipment from the 1930s to the late 1950s.

Currency Counter In the 1950s the Electronics Division of the National Bureau of Standards designed and built an electronic currency counter for the U.S. Department of the Treasury. The currency counter automatically counted stacks of 100 worn-out $1 bills returned to the Treasury by banks. The currency counter rejected any stacks that contained more or less than 100 bills. The counter eliminated the need for hand-counting, saving the government a quarter of a million dollars annually.
 
Decremeter 1912-1914 The sinking of the Titanic in 1912 pressed governments to set technical regulations on maritime wireless communications. To avoid interference from other electrical devices aboard ocean-going ships, one regulation required that the rate of decay, or "decrement," of wireless transmission waves emitted from antennas not exceed a certain amount. The National Bureau of Standards designed a portable decremeter for use by ship inspectors to easily measure the rate of decay.
Deep Ocean Sampler In the late 1970s the National Bureau of Standards designed an ocean sampling apparatus for use at depths of 10,000 meters, where the pressure was about 1,000 times atmospheric pressure. The deep ocean sampler allowed for pre-pressurizing a sterilized interior sampling chamber, capturing a sample at the required depth, and maintaining the sample at its deep-water pressure while allowing scientists to study the enclosed microorganisms in the laboratory.
Determination of Electrostatic to Electromagnetic Units In 1907 National Bureau of Standards physicists Edward B. Rosa and Noah E. Dorsey conducted an experiment that demonstrated that the measurement of an electrical current in electromagnetic units was related to its measurement in electrostatic units by exactly the numerical value of the speed of light. This was an important confirmation of Scottish scientist James Maxwell's theory of light.
Diet Study Using Liquid Chromatography In 1987 the National Bureau of Standards used the technique of high-performance liquid chromatography to help determine if vitamin A, vitamin E, and beta-carotene in the human diet played a role in preventing cancer.
 
Electron Physics The National Bureau of Standards Electron Physics section had the aim of doing everything with electrons that could be done with light, and the section's work to achieve that aim led it into new and interesting directions. It involved polarization studies; elastic and inelastic scattering from both solids and gases; and an improved way of studying multiple scattering events by measurement of total energy loss.
Emery Testing Machine This collection contains photographs of the Emery Testing Machine, which was used to further NBS’ work in structural materials. Planning expansion of both the Bureau’s work in structural materials and that of the former Geological Survey group, NBS asked Congress for new mammoth testing machines and a special building to house them. The funds were approved and NBS obtained a 1-million-pound crushing machine for compression tests of brick, stone, cement, and concretes, another of 230,000-pound capacity, a 100,000-pound universal (compression and tension) machine, and a specially designed 2,300,000-pound Emery universal testing machine, for breakdown and exhaustion tests of girders and other large structural members.

Evenson Highest Frequency National Bureau of Standards (NBS) researchers Kenneth Evenson, Donald Jennings and Russell Petersen successfully accomplished the highest direct frequency measurement ever made (over 520 terahertz) in a joint project with the Canadian National Research Council in 1972.

 

Federal Basis for Weights and Measures Report This collection represents graphics and images from NBS Circular 593 “The Federal Basis for Weights and Measures: A Historical Review of Federal Legislative Effort, Statutes, and Administrative Action in the Field of Weights and Measures in the United States,” issued June 5, 1958. The publication presents a largely chronological review, for the period 1776-1956, of congressional efforts and accomplishments in the general weights and measures area, with emphasis on units and standards. In its entirety, the Circular presents a connected and reasonably comprehensive story of the Federal contribution to the legislative basis for weights and measures administration in the United States.

 
Gage Blocks Gage blocks are standardized blocks of known length and thickness, used for precision manufacturing. The National Institute of Standards and Technology has a long history with gage block design and calibration.
Gas Meter Testing Research by the National Bureau of Standards (NBS) Gas Engineering group led to modifications in the street gas lamps in the District of Columbia that increased street illumination by 50 percent, with no rise in the cost of service. The gas industry was further aided by later NBS investigations of gas appliances, gas stoves, and gas furnaces. The results led to notable increases in gas efficiency and safety, as well as in sales.
Graphite Multidisk Electron Beam Calorimeter A graphite calorimeter was developed at the National Institute of Standards and Technology in 1993 for the absolute calibration of high-intensity electron beams.
Hydrometer Testing The hydrometer is an instrument for measuring the density (weight per unit volume) or specific gravity (weight per unit volume compared to water) of liquids. The National Bureau of Standards annually tested hundreds of commercial hydrometers. These tests were of special importance to the chemical manufacturing and petroleum industries. Hydrometers were tested either by direct comparison with standard instruments or with a standard test liquid whose density was determined by hydrostatic weighting.
Jefferson's Address 1790A photographic copy of then-Secretary of State Thomas Jefferson's weights and measures message to the U.S. House of Representatives on January 10, 1790, along with the House's order on Friday, January 15, 1790, that Jefferson prepare and report a proper plan for establishing uniformity in currency, weights, and measures of the United States.
 
Laser Trapping 1991 By 1983, Bill Phillips, an National Bureau of Standards (NBS) physicist, and Harold Metcalf, a visiting scientist from the University of New York at Stony Brook, had assembled in an experiment that demonstrated the use of counter-propagating resonant laser beams to decelerate neutral sodium atoms to about 40 % of their thermal velocities. Within months, Phillips, John V. Prodan, and Metcalf had reduced the equivalent temperature of a neutral sodium beam to about 70 mK, only 4 % of its initial velocity. In April 1983, a 2-day workshop was held at the NBS Gaithersburg laboratory on slow atomic beams. By 1985, the Gaithersburg group learned how to build a magnetic trap to confine the neutral atoms for about a second so that measurements of their properties could be performed. By 1988, the level of cooling reached 40 μK, far below the equivalent temperature limit supposed possible in then-current theories. For his part in leading the way to the use of lasers to cool and trap atoms, Phillips -- by then a National Institute of Standards and Technology (NIST) fellow -- was elected to the National Academy of Science in April 1997. Later that year, Phillips and two of his colleagues, Steven Chu of Stanford University and Claude Cohen-Tannoudji of the Ecole Normale Superieure of Paris, shared the 1997 Nobel Prize in physics. It was the first Nobel Prize for an NBS/NIST employee.

Leather Research This collection consists of images of National Bureau of Standards (NBS) employees engaged in leather research during periods ranging from 1919 to the early 1960s. After the outbreak of World War I, leather became scarce and the search for substitutes began in the 1950s, NBS studied the pore structure of leather and the moisture content of leather as a function of humidity at different temperatures. The study was then extended to development of a new method for the determination of water-vapor permeability in leathers.

Long Range Scanning Tunneling Microscope In 1991 National Institute of Standards and Technology researchers designed an improved Scanning Tunneling Microscope with a 500 X 500 micron field of view.

Low Cost Housing This collection documents the work done by the National Bureau of Standards (NBS) in testing low cost materials for housing. In July 1970, NBS Director Lewis M. Branscomb assigned to James R. Wright, Chief of the Building Research Division, the additional responsibility of cooperating with the Program Office to coordinate NBS efforts with the Department of Housing and Urban Development.

Malcolm Baldrige Awards Portrait File This collection contains photographs of the annual national award given by the President of the United States for industrial excellence. The award was named for Secretary of Commerce Malcolm Baldrige who died in 1987. The collection also includes photographs of the Malcolm 'Mac' Baldrige National Oceanic and Atmospheric Administration (NOAA) Ship.

Mass Standards This collection documents the kilograms and other mass standards held by the National Institute of Standards and Technology. These Prototype Kilograms are representative of the Kilogramme des Archives developed after the Treaty of the Meter was signed in 1875. The Kilogramme des Archives is held by the International Bureau of Weights and Measures in France.

Heroult Furnace

Metallurgy Division The Metallurgy Collection consists of images and publications related to the following the National Institute of Standards and Technology Archives collections: Aluminum from Clay, Studies of Metal Fatigue, Metallurgy Division, Metallurgy Research, Metallurgy Plating, and Prosthesis. The Metallurgy Division was established in 1913 for the purpose of testing railroad materials and technology and performing research in the chemical, physical, mechanical, and structural properties of metals. Since the reorganization of the Material Measurement Laboratory in 2012, the metallurgy program has been part of the Materials Science and Engineering Division. Images within this collection include collections about Rail Accidents, the Heroult Furnace, and Secondary Ion Mass Spectrometry.

Miniature Radio Receivers and Transmitters The images in this collection record National Bureau of Standards research on into miniature radio receivers and transmitters including a wrist watch transmitter conducted during the 1930s and 1940.

Navigation Research This collection documents navigation instruments and the methods used to develop them. Instruments include: a radio compass developed by Frederick A. Kolster that enabled a ship to establish its position by determining with high accuracy the direction of sending station signals; and a tuned reed course indicator used with a radio beacon that gave an aircraft pilot a visible indication of whether he was on course.

 

Neutron Activation Autoradiography The Reactor Radiation Division of the National Bureau of Standards and the Smithsonian Institution collaborated on a project to study by neutron induced autoradiography and gamma spectroscopy the works of painter Thomas Wilmer Dewing (1851-1938). This technique, undertaken in 1986, allowed the observation of multiple pigment applications beneath the surface of an oil painting, offering the art historian an unparalleled opportunity to observe the working method of an artist from the ground up.

NIST User Facilities Brochure The collection contains images and graphics from an October 1988 brochure highlighting user research facilities at the National Institute of Standards and Technology. The photographs are of researchers using facilities such as the Small-Angle Neutron Scattering Facility and the Large-Scale Structures Testing Facility, along with images of the instruments used in many of the facilities including the Acoustic Anechoic Chamber.

Nylon Rope Strength Test In the 1940s the NBS tested the strength of nylon safety ropes.

Optical Glass In the early 20th century glass for the optical systems of telescopes, microscopes, field glasses, navigation and surveying instruments, cameras, and similar instruments was expensive to make and had a limited market. Therefore, American optical firms imported their quality glass. World War I, however, abruptly cut off the supply of optical instruments and optical glass to the U.S. In 1914, The director of the National Bureau of Standards (NBS) ordered furnaces and apparatus for the field laboratory in Pittsburgh, and set it to work studying the manufacture of optical glass. This collection of photos depicts glass operations at NBS from the 1920s to the 1940s, and beyond.

Ordnance from World War II This collection illustrates the development of aerial ordnance at the National Bureau of Standards (NBS) during World War II and beyond. NBS developed ordnance for both the Army and the Navy, which included radio proximity fuses for rockets and bombs, and guided missiles, including the “Bat,” the first fully automatic guided missile used successfully in combat. This collection includes the smaller Bat Missile Photographic Collection.

Panama-Pacific International Exposition, 1915 The Panama-Pacific International Exposition was a world's fair that took place between February 20, 1915 and December 4, 1915 in the Marina District of San Francisco, CA. The National Bureau of Standards (NBS) and the Smithsonian Institution created extensive exhibits for the exposition. Included in the exhibits were replica weights and measures of various sizes, and a miniature standard test railway car. This collection’s photographs document the interior of the exhibit hall with NBS displays and exhibits.

Paper Research Using funds provided by the Carnegie Foundation, National Bureau of Standards (NBS) scientists researched the permanence of Government writing papers, the preservation of records, and of library storage conditions. The investigation culminated in NBS's work on the preservation at the National Archives of the originals of the Declaration of Independence and the Constitution of the United States.

Photoionization Mass Spectroscopy at NBS, 1964 to mid-1980's This is collection contains photos of the National Bureau of Standards photoionization mass spectrometer constructed by Vernon Dibeler and R.M. Reese and reported in the Journal of Research of the National Bureau of Standards Vol. 68A (1964), p. 409. This instrument was one of the first of its type in the United States and was used by Dibeler and his collaborators, K.E. McCulloh and James Walker, for many pioneering studies of ionization phenomena in small molecules.
Photometric Standards One difficulty in establishing a uniform standard of light hinged on the use of the term "candlepower." The flaws that former National Bureau of Standards Director Edward B. Rosa's group found in the Hefner standard shortly after the establishment of the Bureau led him to propose a new standard for the electric lamp industry -- the mean value of a number of 16-candlepower commercial lamps -- and make this applicable to gas light as well as to electric light. When the value of this new standard "candle" proved to be only slightly greater than the unit maintained by the national laboratories of England and France, the Bureau proposed an adjustment of its own value looking to an international candle. The proposal was accepted, and in 1909 the new value, based on a simple relationship between the British Hefner unit, the French bougie decimale, and the carbon-filament unit maintained in Washington, became the standard for all photometric measurements in this country.
Physics Division Physikalisch-Technische Reichsanstalt Photos of the Physikalisch-Technische Reichsanstalt, the national metrological organization of Germany.

Polymers Division Collection The Polymers Division Collection is comprised of images and publications related to the following National Institute of Standards and Technology Archives collections: Dental Research, Plastics Research, and Rubber Research. The Polymers Division was established in 1962 from what had been the Organic and Fibrous Materials Division. Since the reorganization of the Material Measurement Laboratory in 2012, polymers research primarily resides in two divisions, the Materials Science and Engineering Division and the Biosystems and Biomaterials Division.

Pressure Measurement Photos of National Bureau of Standards research on pressure measurements, including: the Diamond Anvil Cell, developed at the National Bureau of Standards in 1958. It was used to compress sub-millimeter-sized materials to very high pressures; and the Tetrahedral Anvil, a compact apparatus for generating high pressure (1959).

Project Tinkertoy Project Tinkertoy was the code-name for a development and proof of concept project undertaken by the National Bureau of Standards (NBS) to create a process for automated manufacture of electronic equipment and for demonstrating it on a pilot production line. While NBS’s modular design was not used directly in industry, the modular design and mechanized production concepts became the customary way of producing electronic equipment. This collection of images includes design models for the plant, plant machinery, and examples of the components produced.

Pyrometry This collection contains images of pyrometry research at National Bureau of Standards (NBS) between 1905 and 1920. By 1921 pyrometric control stations in heavy industry had become “nearly as intricate as a telephone central station,” a far cry from the days when high temperatures were estimated by visual observation. At the request of the industry, NBS made a compilation of almost 20 years of its research data on the industrial applications of pyrometry. The original printing of 2,000 copies of the 326-page manual (“Pyrometric practice” by Foote, Fairchild, Harrison (1921); NBS Annual Report 1921, p. 92), the first book on the subject in this country, was exhausted within 2 months.
Radio Propagation Research The National Bureau of Standards studied radio wave propagation from approximately the 1920s to the 1970s.

Radiosonde In the late 1930s Harry Diamond, Wilbur Hinman, and Francis Dunmore undertook research to devise a practical system of radiometeorography for the Navy’s Bureau of Aeronautics. A year after beginning construction of their unit, Diamond and his group sent up their first model radiosonde and demonstrated its effectiveness in transmitting continuous data on cloud height and thickness, temperature, pressure, humidity, and light intensity in the upper atmosphere.

Railway Test Car The National Bureau of Standards developed and calibrated test weights for the railroad industry.
Redefinition of the Meter Beginning in 1960 the NBS helped redefine the meter, basing new definitions of length on natural constants.

Reflecting Telescope The most ambitious undertaking in the history of the National Bureau of Standards (NBS) glass plant was its casting of a 69.5-inch disk for the mirror of a large reflecting telescope. At the time, there were not more than 10 optical glass plants in the world, all abroad, capable of making such a disk. The images in this collection document the work to design and pour the disk.

Refrigerants Research (Chlorofluorocarbons) In the 1980s the National Bureau of Standards studied the properties of refrigerants to help industry find effective and more environmentally-friendly replacements for chlorofluorocarbons (CFCs).
Riefler Clock The Riefler clock served as a national time interval standard from 1904 until 1929.
Robotics This collection contains images of the National Institute of Standards and Technology robotics laboratory in the mid - 1970s. A major goal of the laboratory was to achieve intelligent control of machines, so that they would quickly and efficiently turn out work that consistently met design specifications.

Rubber Research Until the rubber section was set up at the National Bureau of Standards circa 1911 there had been almost no rubber research in this country. The exhaustive testing of rubber products at the Bureau constituted some of the first real research in the field. Successive editions of the Bureau circular on testing rubber products that first appeared in 1912 became the bible of the industry. By the mid-twenties much of the Bureau work in rubber was concerned with tire construction, quality, care and use. By the late twenties testing extended to more basic research, including comparative studies of natural, reclaimed, and synthetic rubbers.

SEAC Computer Construction of the (Standards Eastern Automatic Computer (SEAC) began in the fall of 1948 in the National Bureau of Standards (NBS) Electronics Division by a group under Samuel N. Alexander, and with active collaboration by members of the Machine Development Laboratory. NBS was positioned to build the SEAC after gaining experience creating electronic components and devices during World War II. Thus, the SEAC was the first computer to use solid-state electronics extensively.

Second Sound (1949) In 1949 the National Bureau of Standards studied the velocity and attenuation of second sound, the name given to the wave motion of heat in liquid helium cooled to near absolute zero.
SENKPLOT Software SENKPLOT was a software program developed at the National Institute of Standards and Technology for rapid analysis of chemical kinetic numerical simulations.
SIGMA (June 1989) The Supersonic Inert Gas Metal Atomizer (SIGMA) was an instrument used at the National Institute of Standards and Technology in the late 1980s for research on automating the production of rapidly solidified metal powders.
Signaling Mirrors (1945) During WWII the National Bureau of Standards helped devise an improved signaling mirror to be included in military rescue and emergency supplies.
Sound Standard Research (1930) Research undertaken in the acoustical laboratories of the National Bureau of Standards.

Space Beads SRM When the U.S. space shuttle “Challenger” landed in 1983, a measurement problem landed with it. On board was a packet of several billion polystyrene beads, formed into nearly identical spheres during Challenger's flight. NASA designed an apparatus to duplicate bead preparation in space and the National Bureau of Standards examined and measured the beads made in the weightless environment of space. The new Standard Reference Material (SRM), the first space-produced beads to be offered for sale, was given the identification SRM 1960. The images in this collection cover the development of the beads and a press conference announcing the production of the new SRM.

Spectroscopy Research For almost a century before the founding of the National Bureau of Standards (NBS), analysis of chemical elements through their emission spectra had been the subject of studies in Europe. It was well known that each chemical element or combination of elements has distinctive spectra. Yet in that time practically none of the spectra of the elements had been completely described. Upon his arrival at NBS as a young laboratory assistant in 1914, Dr. William F. Meggers began the measurement of wavelengths of light and their application to an understanding of the spectra of chemical elements.

St. Stephen's Robe During World War II the National Bureau of Standards helped preserve some of their important historic relics for the country of Hungary.

Standard Reference Materials The National Institute of Standards and Technology (NIST) supports accurate and compatible measurements by certifying and providing over 1,200 Standard Reference Materials® (SRMs) with well-characterized composition or properties, or both. Among the historical images related to SRMs:

 DNA Prototyping NIST developed Standard Reference Materials for use in improving quality control for DNA "fingerprinting" techniques.

Hydrocarbon Standard Samples This collection contains photographs of hydrocarbon standards research during the 1940s at the National Bureau of Standards.

Line-width Standards August 1987 - Carol Vezzetti and Sam Jones used a modified optical microscope linked to a data-collection computer to calibrate National Bureau of Standards photomask SRMs. [From NBS Research Reports, August 1987.]

Images of NIST Standard Reference Materials are also available in the NIST Museum Artifacts collection.

Sundial This collection includes photos of a unique commemorative sundial on the National Institute of Standards and Technology campus.
Surface Science, February 1987 Surface Science February 1987 With a scanning tunneling microscope, Drs. Robert Dragoset, Daniel Pierce, Robert Celotta, and Stanley Mielczarek studied the structure of surfaces and interfaces to determine how changes affect their properties.

SWAC Computer Dedicated on August 17, 1950 at the Institute for Numerical Analysis at UCLA, the Standards Western Automatic Computer (SWAC) was the companion computer to the SEAC (Standards Eastern Automatic Computer). It was to handle special problems of the aircraft industry on the west coast for the Navy Department, as well as engineering, physics, and mathematical calculations required by the National Bureau of Standards and by other Federal agencies in the area.

TC-2 Temperature Controller This collection includes photos of the temperature controller for the National Institute of Standards and Technology’s Low Background Infrared Calibration Facility.
Weight Accuracy Test National Institute of Standards and Technology calibrations of weights and measures.

Wind Tunnel This collection documents a wind tunnel building which began operation in January of 1918. The wind tunnel that Dr. Lyman J. Briggs designed housed a 9-foot propeller that produced air speeds of 90 miles an hour. In it Briggs installed recording apparatus and began his measurements on airfoils and on airplane and dirigible models. In almost continuous operation, the wind tunnel was also used to make studies of wind stresses, to test airspeed indicators and similar instruments, and to determine the flight characteristics of aerial bombs.

WWV Radio Since 1923, the National Bureau of Standards (now the National Institute of Standards and Technology) has operated radio stations that broadcast standard time and frequency signals that were used as both time and frequency standards. These signals were the basis for setting clocks and were widely used for navigation, for setting frequencies of broadcast stations, and for other uses in which accurate frequency control was important. WWV locations have included Washington, D.C. (1923-1931), College Park, Maryland (1931-1932), Greenbelt, Maryland (1932-1966), and Fort Collins, Colorado (1966 to the present).

X-Ray Standardization At the National Bureau of Standards, Lauriston S. Taylor’s work on the absolute measurement of X-rays, published in 1929, showed that the roentgen could be precisely measured, and resulted in the first real quantitative data on X-ray standards in this country. Working through the National Committee on Radiation Protection and Measurements (the American counterpart of the councils working on standards in Europe), Lauriston Taylor’s X-ray safety code in 1931 established guides for the shielding of operating rooms and of high voltage equipment and for protective devices for patients and operators.
