Professor Colin Garfield Fink of Columbia, who invented the drawn tungsten filament for electric light bulbs and developed the first commercial process of plating automobile hardware with chromium, last week announced that he was successfully electroplating objects with tungsten...
Just as molybdenum and tungsten were obscure metals until it was found that they alloyed with steel to make a superlatively hard cutting material, so beryllium, discovered in 1797, has until recently remained unnoticed...
...incident of the Manhattan meeting of the American Institute of Electrical Engineers last week (see below) was Dr. Matthew Luckiesh's presentation of his new General Electric sunlight lamp. The bulb is 6¼ in. long. It contains two separated tungsten electrodes, a little pool of mercury, a tungsten filament. When the electric switch is turned, current heats the filament to incandescence. The heat vaporizes the mercury. The mercury vapor diffuses between the electrodes and permits the current to jump across as a brilliant mercury arc. The combined light of arc, electrodes and filament appears much whiter than Mazda...

...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...
