One man rubber life rafts are standard equipment in all Navy single-seat fighters. The raft is packed and stowed below the turtle back immediately behind the pilot's seat. After a landing at sea, the pilot pulls out the raft, turns the valve on the bottle of CO2 and the raft inflates in one minute. To get onto the raft requires much the same dexterity as getting into a canoe. Pilot grabs opposite side of raft and throws himself horizontal across the boat

Production. New Tennessee Valley Authority synthetic ammonia plant. Operating a valve servicing on of the gas compressors in the TVA's new synthetic plant in the Muscle Shoals area. Ammonia is made here by the high-pressure synthesis of nitrogen and hydrogen. The ammonia thus secured is converted at Muscle Shoals to ammonium nitrate for use in the making of high explosive shells. In addition to the production of munitions, the TVA is engaged in research in many fields, seeking new sources of strategic materials and better ways to utilize them in the war effort

Production of butylene glycol. Dr. George E. Ward turns a valve in one of the experimental fermentation vats in which corn is being converted into butylene glycol at the Northern Regional Research Laboratory of the U.S. Department of Agriculture at Peoria, Illinois. This is part of the laboratory work that led to the development of a fermentation process for converting corn and other grains into butylene glycol on a semi-commercial scale. Butylene glycol can be used in making anti-freeze for automobiles and in the production of commercial solvents for various manufacturing purposes. Department scientists have succeeded on a laboratory scale in turning butylene glycol into butadiene, from which synthetic rubber can be made. Now they are trying to do it on a semi-commercial scale

DeLand pool. Improvised foundry, Daytona Beach. American ingenuity is the keenest tool in the kit of the machinists turning out war weapons in Florida's pools. This is the way J.L. Clayton, Daytona Beach fireman, figured out and built a blast furnace hot enough to melt brass and aluminum. He hooked up a fuel oil barrel to the old foundry pump shown at right. The pump blasts the oil and compressed air down the pipeline into the crucible. Arthur Brown, Negro helper, has his hand on a valve that controls the air and fuel which heat the furnace

Seating the valve and seaming the tube. After each tube is snipped off at the proper length, it passes to this worker who places the open and over a sleeve, and forces the valve into position right in the center of reinforcing patch. This makes doubly sure that the tube is absolutely leak-proof. When this is done, the cube can be seamed shut--the operation which is taking place here. The two ends are butted together, the sticky rubber is bonded together under pressure, and passed on to the curing molds for vulcanizing. Firestone (General), Akron, Ohio
