Six stages of fat salvage. Saponification of fats makes glycerine. Glycerine makes explosives and camouflage paints. In this giant soap kettle, in a great industrial plant, fats become soap. When salt is added, the liquid part of this mixture will drop to the bottom of the kettle. That liquid will soon become glycerine

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

Production. Pipe fittings. Beveling a large pipe elbow to prepare it for butt welding. Elbows like this, for use in Army equipment, are made by bending straight pipe in a large Midwest plant. Tube Turn Incorporated
