...elder brother,* Walter Carpenter is not even a Du Pont-in-law. Quitting Cornell in his senior year to take a Du Pont job in Chile, he loped to the head of the development department which completed the conversion of Du Pont, after World War I, from a great powder company to a greater chemical-technical empire. Since 1921 he has been the company's treasurer. Spare, hardworking, determined, he lives quietly in a rambling old stone house in Wilmington's fashionable Rising Sun district, consistently beating his three sons and Lammot at tennis...
...silk hose demand. A second plant, now building, will not swing into full production for a year. Discouraging, too, to hosiery makers was the possibility of nylon's becoming a war material. Last week the U. S. Army was testing the yarn for use in making parachutes, powder bags...
...inch armor ceiling-a total of 13¼ inches of armor. But the bomb would explode and stop penetrating when it hit the very first deck. Alternatively, it would have to penetrate the 10-inch armor of a turret barbette; or blast in through a gunport, ignite a powder train down through an elevator to the magazine. Ever since three British capital ships were blown up at Jutland by failure of their flash screens, turret design has been perfected to render such accidents next to impossible. Clever though their story was, the Germans' "battleship bombed" screamer was to naval...
When fluorescent lighting showed commercial possibilities several years ago, Hygrade researchers went quickly to work. Mercury vapor inside fluorescent lamps is ionized by an electric discharge between electrodes at each end, produces short ultraviolet rays which must then be converted by a fluorescent powder to visible light. In February Hygrade's chief research engineer, James L. Cox, got an award from N. A. M. for a new method of coating the lamps with a porous powder so that longer rays of the visible range are efficiently radiated. Costly to install, fluorescents waste only 75% of their energy in heat...
