Conversion. Copper and brass processing. Many parts and products used by the Army and the Navy must stand up under severe service conditions. Here the strength of a specimen of brass is being determined. The results of these tests enables engineers to select metals that have the strength and stiffness needed for various machined parts for guns and equipment. This testing machine records the tensile of yield strength of a metal specimen--its resistance to being pulled apart. A specimen in the machine is pulled until it breaks, and the load necessary to break is recorded. A meter attached to the specimen measures the amount of stretching. Chase Copper and Brass Company, Euclid, Ohio

Studying why fruits taste that way. E.K. Nelson of the Department of Agriculture is shown making tests with an apparatus which the Department imported from Germany for the purpose of studying the essential oils or "flavor-giving" content of fruits and vegetables. At present chemists are acquainted with the essential oils of only a few fruits, such as some of the citrus group. The apparatus is a vacuum distill which permits the distillation of liquids at temperatures much lower than usual by reducing the pressure, 1/10/31

Conversion. Copper and brass processing. Stocks of partially completed lengths of seamless copper tube in many sizes. These have still to go through several more draws through dies on drawbenches. Each draw reduces them in diameter and wall thickness, and lengthens them out. Then, before the tubes leaves the mill, the ends will be sawed off straight and clean.
