...into the earth's crust, to tap a store of heat 31 million times as great as all the heat stored in the world's aggregate coal deposits. A 30-mile bore, one foot in diameter, could obviously not be dug by human labor. But an eroding alloy of aluminum would do it, melted by electricity, circulated by hot air at a pressure of more than 250,000 Ibs. to the square inch. That is about the pressure of the earth's rocky crust 30 miles down, a pressure under which the friction of rock layers sliding...
...Great dirigibles, constructed of alloy metals and as large as passenger litters, will take care of the trans-Atlantic trade of the future," affirmed General Umberto Nobile, constructor of the airship Norge, in an interview with a CRIMSON reporter yesterday. General Nobile spoke at the Harvard Union last night on his flight to the North Pole...
...flame left molten pools behind it. Significance: steel girders could be welded silently instead of noisily riveted;* the welds would not (as when an oxyhydrogen flame is used) be oxidized and thus weakened, they would be annealing instead. This is important in joining aluminum, magnesium and other light metals.) Alloy metals, too refractory to work with by present methods, could be used for building, thus conserving the world's iron...
Cyrus Stephen Eaton, Nova Scotian, now of Cleveland, worked last week on the $80,000,000 merger of the Central Steel Co. of Massillon, Ohio, and the United Alloy Steel Corp. of Canton, Ohio. Their combined ingot capacity will Approximate 1,400,000 yearly. They will be the sixth largest steel corporation in the U. S., the very largest specializing in alloy steels...
...cable, 2,500 letters a minute, is to result from an improvement achieved in the cable itself after long experimenting to gain speed by improving sending and receiving instruments. Around the copper conductor of the 3,800-mile strand is wound a continuous strip of "permalloy" ribbon, an alloy of iron and nickel which conducts current very freely, permitting signals to be sent close together...
