How much wear will your carpet stand? Washington, D.C., March 19. A machine that produces the bending, slipping, twisting, and compression of the pile that takes place when a carpet is walked upon, has been developed by the National Bureau of Standards to test the durability of carpets. H.F. Schiefer, physicist at the Bureau, is shown in the photograph, 3/19/38

Rating gasolines at the Bureau of Standards. Washington, D.C., April 17. F.R. Carter of the U.S. Bureau of Standards is shown adjusting the mixture of gasoline to find out the rating in octane numbers of gasolines. The three carbureter shown in the foreground are each filled with a gasoline tow of which with a known octane rating and the third is filled with the sample to be tested, this machine has a variable compression ratio and can be changed while in motion

Forest Products Laboratory, Madison, Wisconsin. A compression test on a veneer cylinder using an electrical strain gauge. Great pressure is exerted on the cylinder and the resultant strains and stresses are registered by the electrical contacts on its surface. Much experimenting is being done on veneers suitable for use in aircraft
