Interferometer tests standard gages for automobile manufacturers. Washington, D.C. May 28. I.J. Fullmer of the Bureau of Standards is shown with an interferometer by means of which differences in length are measured in terms of wave-lengths of light to the millionth of an inch. A four-inch square precision gage is being compared for length with the Bureau's standard 4 inch, which is rectangular in shape. These gages are tested against the master gages which the different auto manufacturers check their measuring devices so that the parts of the cars separately made can be, when assembled, fitted perfectly. The standard gage and the master gage are shwon being compared in the interferometer, 52837

Auto manufacturers send representative to tell of Labor Act's 'glaring weaknesses.' Washington, D.C., June 27. The automobile manufacturers' associations, represented by William J. Cronin, its secretary, told the Senate Education and Labor Committee that the present Wagner Labor Act is surrounded by 'glaring weaknesses.' Reviewing sit-down strikes, he said that General Motors plants had alone had 40,000 workers idle and had a payroll reduction of more than $10,000,000 as a result of sit-down strikes. He recommended amendments to allow workers to choose bargaining agents without interference, and a clause to make both parties of agreements equally liable for violation. He is shown here pointing out enlarged clippings from the Detroit news which reproduced enlarged 'mugs' from police files to show certain leaders of automobile labor to have criminal records

U.S. experts test weather device. Washington, D.C., Sept. 13. Scientists of the National Bureau of Standards today conducted a test of the new radiometeorograph, a device attached to parachute and balloon and sent into the skies to radio back signals giving the pressure, temperature and humidity of the upper air. Preparing the balloon for the ascension are Dr. L.V. Astin, (left) of the Bureau's Electrical Division, and Dr. L.F. Curtiss, head of the Radium Division. The balloon carries the instrument as high as 50,000 or 60,000 feet. 9 to 11 miles high. Today's test was conducted for the U.S. Weather Bureau. 9/13/37

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

Giant tire manufacturer. Final inspection of the world's largest tire, the 36.00-40 earth mover, used in the construction of airports and new army camps. This huge tire stands nine and a half feet high, with tube and flap, weighs 3,646 pounds and carries 55,000 pounds. The giant mold in which it is vulcanized weighs 300,000 pounds and stands two and a half stories high when the cover is open. The top section of the mold which is raised and lowered to admit the tire, weighs sixteen tons. Large bullet- sealing gasoline and oil tanks are also being cured in this mold

Studying why fruits taste that way. E.K. Nelson of the Department of Agriculture is shown making tests with an apparatus which the Department imported from Germany for the purpose of studying the essential oils or "flavor-giving" content of fruits and vegetables. At present chemists are acquainted with the essential oils of only a few fruits, such as some of the citrus group. The apparatus is a vacuum distill which permits the distillation of liquids at temperatures much lower than usual by reducing the pressure, 1/10/31

Citations of individual production merit awarded. The first five Citations of Individual Production Merit have been awarded to five war workers, War Production Drive Headquarters has announced. The citation is the highest honor conferred for individual achievement. It is granted only for ideas or suggestions that have an outstanding effect on the entire war effort. Joseph H. Kautsky, Indianapolis, Indiana, an employee of the Lin-Belt Co., was awarded his citation for four suggestions, each technical. He suggested a grinding wheel adapter, which permits higher speeds in internal grindings; a simplification cutting down the number of special internal grinding spindle wheel adapters from twelve to three; the adoption of a precision screw adjustment to the vertical column of dial indicator guages, to get faster adjustments without danger to the dials; and a new method of testing the concentricity of internally ground parts. The picture shows Mr. Kautsky (center) being congratulated by formean Bill Whitaker (right) as Superintendant R. E. Whitney (left) looks on

In this group are some of the youngest workers in Spinning Room of Cornell Mill. The smallest is Jo Benevidos, 5 Merion St. Other small ones are: John Sousa, 84 Boutwell St., Anthony Valentin, 203 Pitman St. Manuel Perry, 124 Everett St. John Travaresm [or Taveresm?], 90 Cash St. The difficulty they had in writing their names was pathetic. When I asked the second hand in charge of the room to let the boys go outside a moment and let me get a snap-shot he objected, saying they would stay out and not be in shape to work. When they carry dinners, they breathe the close air of the spinning room from 7 A.M. to 5:30 P.M. with no let-up. Cornell Mill. Location: Fall River, Massachusetts.

Production. B-24E (Liberator) bombers at Willow Run. Another B-24E (Liberator) bomber nears completion on one of the assembly lines at Ford's big Willow Run plant. A paint job comes next. The Liberator is capable of operation at high altitudes and over great ranges on precision bombing missions. It has proved itself an excellent performer in the Pacific, in Northern Africa, Europe and the Aleutians. Ford's Willow Run Plant, Michigan

Baltimore, Maryland. The "work" cards, by means of which constant check is kept on what is being done with each block of Social Security Account Applications, are punched in the Production and Control Section. Each hole in each "work" or peration, card represents a letter or a numeral. When translated, these give necessary pertinent data for the daily permenent work records of the Social Security Board Records Office in Baltimore.
