Uncle Sam test brass alloys. Washington D.C. To determine the correct amount of alloys necessary for desired results in the making of castings and other uses, the U.S. Bureau of Standards is conducting daily tests. 600 different portions of the alloy are used at the present time. The tests are made with brass bars which are melted in a high frequency induction furnace and the temperatures are recorded before and during the pouring into the molds. In the photograph, left to right: H.V. Gardner, Lemuel D. Jones, and C.N. Saeger, Chief of the Experimental Foundry at the Bureau

Photoelectric ray to determine flying ceiling. Washington, D.C., June 15. To permit a ground observer to determine at what height flying is safe during days of fog and heavy overcast, Miss Elizabeth M. Zandonini, of the Radio Section staff of the Bureau of Standards, is shown with the balloon transmitting equipment. A photoelectric cell measuring light brightness is used to control the pitch of the radio signal transmitted from the balloon as it ascends. A graphical frequency recorder plots the pitch and hence [...] a measure of the light brightness as a function [...] height. The experiments are carried on for the U.S. [...]
