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

Steel manufacture, Allegheny-Ludlum. No lumberyard this! These are billets of stainless steel, ready to through the hot rolling mills to be pressed into strips. The chipping and grinding on the surfaces of these billets is designed to remove all contamination and defects, so that the steel may meet the high quality requirements of being able to resist corrosion

Production. B-17F heavy bomber. Machine screws to be used in building new B-17F (Flying Fortress) bombers in the Boeing plant in Seattle are attached to hangers which suspend them in anodizing tank. In the tanks they will receive a protective plating to prevent corrosion. The Flying Fortress, a four-engine heavy bomber capable of flying at high altitudes, has performed with great credit in the South Pacific, over Germany and elsewhere

Conversion. Beverage containers to aviation oxygen cylinders. Removing of non-shatter-chemical solution tank at a rubber factory now producing metal essential for the Army. This bath, which follows the removal of the weld scale, gives the inside of the cylinder a further cleaning and removes all chemicals which may remain from the previous operation. A satin-like surface, absolutely sterile and free from foreign matter, is made permanent in this operation. The cylinder is now also immune to attack from corrosion and other deteriorating elements.

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
