Conservation of used material bears heavily on the progress of the defense program. From Western Electric's distributing houses used wire and cable is shipped to the Nassau Smelting and Refining Company, where its components are preserved and cast into ingots and billets that find their way back to industry again. At the Atlanta distributing house, a new battery-driven lift and dumptruck speeds the local conservation program

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

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

Production. B-24 bombers and C-87 transports. Center wing sections at a Western aircraft plant now producing consolidated B-24 bombers and transports. The new transport ship, an adaptation of the B-24 bomber, is known as the C-87, and carries one of the greatest human or cargo loads of any plane now in mass production -- and carries these great loads at high speeds

Production. Milling machines and machine castings. It's all a matter of relative angles and turning speeds. Properly set, this gear-cutting machine tool will produce any kind of beveled, spur, hypoid or other kind of gear. The small hypoid bevel gear shown partially cut in the center of the picture will soon become part of another machine tool after it has been heat-treated, ground, lapped and thoroughly tested and checked
