...Scientists have already succeeded in changing nitrogen into hydrogen by the action of alpha particles. This feat was accomplished by Rutherford some time ago. Another investigator has reported a change of tungsten into helium at a very high temperature, but scientists in general consider his results as unconfirmed. The work of Rutherford has been duplicated by several other investigators and his transmutation of nitrogen into hydrogen is accepted as a fact...
...mainly directed against a contract system between the General Electric and several companies engaged in distributing electric bulbs, as preventing competition. The petition declares that the Company does a business amounting to about $50,000,000 a year. General Electric claims patent rights for the exclusive manufacture of tungsten filaments used in the better grade of bulbs today...
...larger than a grain of rice, was exhibited at the Sprague plant of the General Electric Company, East Orange, N. J. The monster bulb is of 150,000 candlepower and requires four large cables to supply the 30,000 watts it burns. Four long strips of heavily corrugated tungsten steel were used as filaments. The heat generated reached 3,200 degrees Centigrade, melting the glass. A large electric fan was used to cool the air. The inventor, George Bowerman, is experimenting with a type of quartz glass to withstand the heat. Red rays are absent from the spectrum...
...this Mr. Jim Blake, of Glens Falls, New York, writing in The Outlook, would reply that the Admiral overlooks the claims of pig iron. Pig iron doesn't relish its limitations. It would like nothing better than an infusion of tungsten. And it suffers when it is told to stay pig. Mr. Blake refers particularly to Dartmouth, which, since it has launched upon a career of excellence, has been quite tactless in its expulsions. Nearly 300 Sophomores and Juniors, as well as Freshmen, were expelled last midyear. "It was pitiful," says Mr. Blake, "to see the distress. Some were...
...form now any final judgment upon the highly interesting news from Chicago. Dr. Wendt is a careful and intelligent experimenter, and the presumption is therefore in favor of his conclusion. If he has good reason to believe that he has obtained any considerable amount of helium from pure tungsten, the discovery is very important, and its remote consequences cannot be foreseen...
