Civilian defense. There's not much that is omitted in the equipment of these special gas and electrical emergency trucks. On the floor in front of the trunk are, left to right, the following items: a fitter's kit for repairing small gas leaks; a rubberized blanket for electrical work; an atmosphere testing machine; an inhalator; a Phister fire extinguisher; an air blower ; a lux fire extinguisher kit; a splicer's kit containing insulated hand tools; a fuse kit; a manhole guard rail and a rubber mat for electrical work. The worker at the left is wearing a special mask with a half-hour suplly of oxygen for use where a fresh air hose is not practical. He is also wearing rubber gloves for repair work. The man standing in the center is holding a hand operated manhole pump. The truck and its equipment were on display at Madison Square Garden, New York, as part of the huge civilian defense show held there in October

Anaconda smelter, Montana. Anaconda Copper Mining Company. Poling in the refining furnace. Wooden poles are plunged into the molten copper; there is a great evolution of gases when this is done and the excess oxygen combines with the carbon of the wood and passes off as carbon monoxide. This refining of blister copper is based upon the fact that oxygen has a stronger affinity for the impurities in the charge than it has for copper

Conversion. Beverage containers to aviation oxygen cylinders. Once the two-half cylinders are joined together into a complete shatterproof high altitude flying oxygen cylinder on the production line of a huge rubber factory now producing metal essential for the Army, all traces of inside weld scale must be removed to prevent contamination of oxygen. In this process, a special chemical solution is drawn through the cylinder at controlled temperature and all foreign matter is removed. Firestone, Akron, Ohio

Conversion. Beverage containers to aviation oxygen cylinders. The first step in the manufacture of high-altitude-flying shatterproof oxygen cylinders in the metal department of a large rubber factory is the forming or stamping of the shell. Stainless steel sheets are blanked or cut into discs(left foreground). Before stamping, these discs are drawn through rolls where a drawing compound is added to both sides to facilitate the forming of the shell. The 750-ton toggle press, shown above, forms a half cylinder in one powerful stroke. Once the half cylinder is formed, it is trimmed and the value-fitting hole is punched into the spherical dome. A cleaning operation later removes the drawing compound. The cylinder halves are now ready for the various welding operations. Firestone, Akron, Ohio

Conversion. Beverage containers to aviation oxygen cylinders. Before completion of the fourth and final welding operation in the manufacture of shatterproof oxygen cylinders for high altitude flying, all straps are subjected to physical tests to determine the strength of the weld. Occasional radiographic inspections are made to insure the quality of workmanship and materials after the atomic welding machine has brought the two halves of the cylinder together and made into one unit. The operator, looking through a specially designed dark safety glass, rotates the shell by sight to insure a perfect and uniform union of the two halves. Firestone, Akron, Ohio

Anaconda smelter, Montana. Anaconda Copper Mining Company. Poling in the refining furnace. Wooden pole are plunged into the molten copper; there is a great evolution of gases when this is done and the excess oxygen combines with the carbon of the the wood and passes off as carbon monoxide. This refining of blister copper is based upon the fact that oxygen has a stronger affinity for the impurities in the charge that it has for copper

Conversion. Beverage containers to aviation oxygen cylinders. Removing of non-shatter-chemical solution tank at a rubber factory now producing metal essential for the Army. This bath, which follows the removal of the weld scale, gives the inside of the cylinder a further cleaning and removes all chemicals which may remain from the previous operation. A satin-like surface, absolutely sterile and free from foreign matter, is made permanent in this operation. The cylinder is now also immune to attack from corrosion and other deteriorating elements.
