...remarkable brick rewarded the country's important chemical societies for giving the coveted Perkin Medal to Dr. Charles Frederick Burgess at a Manhattan ceremony last week. The medal is for "the American chemist who has most distinguished himself by his services to applied chemistry." In Dr. Burgess' case that refers to his showing factory managers that it pays to hire scholars. Twenty and more years ago he was professor of applied electro-chemistry and chemical engineering at the University of Wisconsin. Manufacturers hesitated to use his novel ideas concerning the electrolytic purification of iron, dry batteries, corrosion...
Original idea for the brick belonged to Howard F. Weiss, Manhattan chemist who figured out that what with loading, hauling, hod-carrying and mortaring, it costs four times as much to lay a brick as to make...
...theologians thought of hell in terms of fire and brimstone-volcanic heat coming from inside the earth, whose core is probably no hotter than 1,500° C. Modern electrical engineers can produce steady temperatures of 2,000° C. in furnaces for the steel industry, and fortnight ago Chemist Robert Browning Sosman of U. S. Steel Corp. announced that with a heliostat and focusing mirror he had been able to capture 3,000° of the sun's heat (TIME, Dec. 21). With gas, temperatures as high as 4,600° have been obtained, but they could...
...probably took the trouble to learn that the glass gathered together the sun's diffused rays and concentrated them on one spot, raising their temperature to the burning point. But even that temperature was far lower than the 6,000º C. on the sun's sizzling surface. Last week Chemist Robert Browning Sosman of U. S. Steel Corp., announced that by extending the principle of the magnifying glass he was able to capture half of the sun's 6,000º heat. With a big specially-built heliostat (reflector) he reflected sunlight on a focusing mirror; the mirror concentrated the rays...
...onetime President, was elected head of Compania Hulera Mexicana, newly organized to make synthetic rubber. In January the company will have a factory ready to produce 400 motor tires and 5,000 rubber heels daily. The formula is the work of one Julio Tellez Giron, 46, research chemist who spent 17 years developing his theory that petroleum in its early stages closely resembles rubber. His process is to take crude petroleum, mix it with ground sugar cane. This compound is refined, fried in the sun, vulcanized with sulphur.* Compania Hulera Mexicana is capitalized at $115,000, has for directors...
