Government discovers method to preserve movie film indefinitely. Washington, D.C., July 8. People living in the year 2000 will be able to see and hear today's history in the making through experiments on preserving movie film now being conducted by the National Bureau of Standards. The experts at the bureau recently completed "accelerated aging tests in which films in six months went through the effects of 50 years' storage in a cool dark room. These tests showed that cellulose, or explosive film, would last from 50 to 100 years. The new Safety or Acetate film "may be preserved for longer periods." Unofficially, the experts put the figure at several hundred years. The following set of pictures were made at the Bureau of Standards and the National Archives Building. (1) Accelerated aging, The stability of the films is tested similarly to paper. They are heated in this oven at 100 [degrees] C and tested for loss of flexibility and for evidences of chemical decomposition. Arnold Soorne, of the Bureau Staff, is picture making the test

Government scientist cools water to -6ʺ without freezing it. Washington, D.C., Aug. 9. The belief that water freezes at 32 degrees fahrenheit has been blasted by Dr. N. Ernest Dorsey, scientist of the National Bureau of Standards. Neither does all water freeze at the same temperature. These discoveries have been made by Dr. Dorsey after experimenting with 37 specimens of water taken from lakes, canals, and other sources. He has cooled water until it was minus 6 degrees fahrenheit that is, 38 degrees colder that the so called freezing point of 32 degrees. Yet it remained liquid, 8/9/38

Bureau of Standards puts ruge insulator through pressure tests. Washington, D.C., Nov. 30. H.L. Whitemore, (left), chief of the Engineering Mechanics section, National Bureau of Standards, and Dr. A.H. Stand, make a final check of the huge 1600[?] pound porcelain insulator before subjecting it to 2,180,000 pounds pressure in the Bureau's hydraulic jack. The insulator, one of the few of its size in existence, will serve as a base for a 640 foot mast at Radio Station WGY, Schenectady, New York. One of the insulators successfully stood the pressure to 800,000 pounds while the second broke when the pressure was boosted to 2,180,000 pounds. The hydraulic jack is capable of exerting 10,000,000 pounds pressure

New machine to test brake linings designed by Bureau of Standards. Washington, D.C., March 16. A new machine, both in design and operations, has been installed at the National Bureau of Standards for the testing of brake linings. The machine permits the study of brake linings under conditions closely approaching those of actual sevice and yet which can be accurately controlled. It will make less difficult the complex job of revising the Federal Government's specification for auto brake linings. Wil. Holt of the Bureau is shown in the photograph, 3/16/38

And now a beer meter. Washington, D.C., May 1. To aid Uncle Same in collecting the tax on the millions of barrels of beer brewed in this country every year, the National Bureau of Standards has designed a master beer meter for use of the alcohol unit of the Bureau of Internal Revenue, U.S. Treasury. Government inspectors employ this master meter in checking the accuracy of the brewery beer meter to determine the volume of beer brewed. In the photograph the large tank receives the liquid [after passing] thru the meter where it is weighed to get [the] true volume. Carl F. Stoneburner is reading [...]

Bureau of Standards speeds up photomicrography with new apparatus. Washington, D.C., Aug. 18. By means of this new apparatus just designed by the metallurgical divisions of the National Bureau of Standards, it is now possible to make 700 micrographs per working day of the structural effect of corrosion on cross sections of metallic specimans. This new machine uses roll film of 900 negatives at one loading, thus dispensing with the repeated loading and unloading of individual film holders by which method the Bureau was only formerly able to make 12 micrographs per working day. Willard H. Mutohler, one of the designers of the apparatus is hown photographing the corrosion on airplace materials, 8/18/37

Measuring relative humidity by radio. Washington, D.C. June 9. The hair element for measuring relative humidity in radio weather sounding balloons has proved innacurate because of very slow response at the cold temperatures encountered in the upper atmosphere. F.W. Dunmore, Radio Engineer of National Bureau of Standards, has just developed a new device for the U.S.Navy which will overcome this effect and at the same time will not be affected in response by temperature. He is shown in the photograph observing a graph on the recorder being produced by radio signals from an ascending balloon carrying the new device. This is the first record obtained with this new developement and shows a repidity of response much greater than the hair hygrometers Hitherto used. 6/9/37

New radio meteorograph developed for the U.S. Navy. Washington, D.C., June 9. The National Bureau of Standards has recently developed for the U.S. Navy Meteorological Service a new radio meteorograph. The new instrument (shown in the picture) is sent up on a 5-Foot balloon and is expected to replace the use of airplanes in upper-air meteorological surroundings. E.G. Lapham, Associate Physicist of the bureau, is shown assembling the new meteorograph in preperation for an ascent. The device transmits audio notes which are a function of temperature and humidity. These notes are interrupted at approximately each 10-millibar increment in pressure, thus identifying each temperature and humidity indication with its respective increment of altitude, 6/9/37

Experts at Bureau of Standards study effect of corrosive soils on specimens of pipe. Washington, D.C., Aug. 8. Of interest to home builders the country over is the study being made by experts at the National Bureau of Standards of the effect of corrosive soils on pipes and protective materials. Samples of pipe which have been buried for four years in fifteen soils differing widely in their characteristics, are being tested. Included are several varieties of ferrous materials as well as copper, brass, and bronze. Soldered and brazed joints, protective materials, and pipe made of a composition of cement and asbestos are also represented. Walter Johnson, of the Bureau, is pictured removing graphitic corrosion from cast iron with an air-driven tool. The corrosion products are too hard to be removed with a brush or by chemical treatment, 8/8/38
