Not illustrated. 1917 edition. Excerpt: ...they joined the collar. The entire cylinder was rammed with sand, care being taken to use good molding material near the weld. A mold box was placed in position at the end of the cylinder, being of sufiicient size to take in the weld, while a brick furnace was constructed around the rest of the cylinder and slightly higher than the top surface. Sheet iron was then thrown across the top in order to make a to a good dull red heat. Of course the gas burners were kept going at the same time; in fact, they were allowed to remain burning during the reaction and for a period of 10 hours after the Thermit steel was poured. This kept up the expansion on the cylinder until the Thermit steel cooled to about the same temperature as the rest of the cylinder. At this time the gas burners were turned off and all air holes leading to the cylinder plugged up. This was done to allow the cylinder to cool off gradually. A total of 24 hours was consumed in the entire heating operation. The weld proved to be successful in every respect, being absolutely free from blow holes and of good dense metal. The cylinder is now in operation and has shown no signs of leakage in spite of the fact that it operates under a constant Pure Carbonfree Manganese and Manganese Copper BY ARTHUR F. BRAID1 On account of the war there has been an increasing scarcity of phosphorus and its wellknown alloys of copper and tin. During the same period the production of brass and bronze, nickel silver, cupro-nickel and other non-ferrous alloys has considerably increased. The manufacturers of these products had therefore to secure other materials which would answer their purpose, The weld on the left required 650 lbs. of Railroad Thermit, the other 850 lbs.
