had been formerly located at Cam bridge. The new building is located on a 23 acre site and provides 128,000 square feet of air-conditioned space. Gardner-Denver Co. has put two new metallurgical laboratories into operation at Quincy, 111., and Grand Haven, Mich. The 64 by 90 foot air conditioned build ing at Quincy is equipped for chemical and physical analysis of nonferrous metals, as well as steel and iron. It also contains special facilities for checking quality of oils, coolants, paint, sand, and water. The Grand Haven laboratory is similarly equipped. Chemical analysis can be made on steel for such elements as carbon, molybdenum, manganese, sulfur, silicon, nickel, chromium, and vanadium. The new laboratories will augment one already in operation at Gardner-Denver's Denver plant.
NBS Discontinues Viscosimeter Checks The National Bureau of Standards will discontinue viscosimeter calibration after December 31, 1957. In making the announcement, NBS said that the action is in line with government policy of withdrawing from those activities that can be carried on by private indus try. Object is to devote the Bureau's resources to meeting science and indus try's demands for new and more accu rate standards. In recent years, the only viscosimeters calibrated by NBS have been the Saybolt, Modified Ostwald, and sus pended level types. However, it was pointed out that most users calibrate these instruments in their own labora tories, using standards available from NBS, the American Petroleum Insti tute, and elsewhere. Calibration of Saybolt viscosimeters had already been discontinued by the Bureau in 1956, due to abandonment of Master Saybolt viscosimeters as standards.
