...gases are used to surface steel. Metals absorb gases, a phenomenon only now being put to industrial use. Konel Metal. News of a new and valuable alloy was despatched to the Congress by Westinghouse Electric & Manufacturing Co. Erwin Foster Lowry, 38, Michigan-born Ohio State graduate, had compounded nickel, cobalt and ferrotitanium. Result was a metal which grew stronger the hotter it was heated. Other metals become weaker with heat. Mr. Lowry's alloy has a tensile strength of 60,000 lbs. per sq. in. at 600° C. (1112° F.). At the same temperature chrome nickel steel...

...competitive groups of metallurgist-salesmen chafed last week at industry's slow take-up of a scientific development-tungsten, carbon and cobalt so combined that they made a new material for cutting-tools. The men on one side were employed by the Carboloy Co., General Electric subsidiary; on the other by Thomas Prosser & Son, for 75 years U. S. selling agents for Krupp. Both Krupp and General Electric have independently developed similar metals. Krupp calls its widia (from wie diamant, "like diamond"); General Electric calls its carboloy...

Without ado he placed a piece of magnetized cobalt steel on a table and in the air some distance above it placed another similar piece. The upper one remained balanced without mechanical support. His explanation was simple: one end of a magnet is positive, the other negative; with two magnets the positive of one attracts the negative of the other, the positive and negative of one repel the positive and negative of the other; cobalt steel can be so highly magnetized that its repellent power can support a relatively large weight against the pull of gravity...

Minerals for Diabetics. Analyzing insulin, whose active principle has not yet been isolated,* chemists find minute traces of cobalt and nickel, so some diabetics are now being experimentally fed with cobalt and nickel salts. Scientists coupled this observation with the known fact that soil qualities modify the characteristics of peoples through the plant life eaten directly or indirectly (through herbivorous animals). Example: In Switzerland where iodine is rare, goitre is common. Feeblemindedness and dwarfism are therefore frequent. The recommendation of Dean Jacob G. Lipman of the Rutgers College of Agriculture was that agriculturists go still further in seeking what proper...
