Tennessee Valley Authority. Looking down the partly-finished generator room of a new addition to TVA's hydroelectric plant at Wilson Dam. Concrete work for the scroll case and draft tube is completed up to the scroll case roof. Located near Sheffield, Alabama, 260 miles above the mouth of the Tennessee River, the dam had an authorized power installation of 288,000 kilowatts, which can be increased to a possible ultimate of 444,000 kilowatts. The reservoir at the dam adds 377,000 acre feet of water to controlled storage on the Tennesse River system

Weighing ingredients. As in any recipe, this measuring of ingredients for the "batch" of the rubber must be done with great care. At this point it is determined whether the raw rubber will be converted into tread stock, fabric gum, tube stock, repair material or mechanical rubber stock. All ingredients--rubber, chemicals, liquids--are placed in the metal tub, and delivered to the mill room for processing. General Tires, Akron, Ohio

Conversion. Copper and brass processing. The inside of a large brass and copper tube mill. Copper tubes are made in many sizes, and in many alloys, and are needed for war production in hundreds of different ways--from small diameter tubing for gas and oil lines in airplanes and tanks and motor cars to large diameter tubes used in construction of our battleships. A tube annealing furnace may be seen to the right. Chase Brass and Copper Company, Euclid, Ohio

Conversion. Copper and brass processing. Drawing seamless copper tube. Rough cast tubes tapered at one end to fit through a die are gripped in the tongs of the electric motor-driven vehicle on the drawbench and pulled or "drawn" through the die to be reduced to the desired size. Tubes usually are redrawn many times; each successive "draw" reduces the diameter, and increases the length. Brass tubes need to be annealed or softened between each draw, but copper tubes can be drawn several times without intermediate annealing. The tapered nose of the tubes may be seen just behind the drawbench operator. Chase Copper and Brass Company, Euclid, Ohio

Conversion. Copper and brass processing. The inside of a large brass and copper tube mill. Copper tubes are made in many sizes, and in many alloys, and are needed for war production in hundreds of different ways--from small diameter tubing for gas and oil lines in airplanes and tanks and motor cars to large diameter tubes used in construction of our battleships. A tube annealing furnace may be seen to the right. Chase Brass and Copper Company, Euclid, Ohio
