...World's Fair site on Long Island, they bored a narrow well 50 ft. deep, lined it with double steel tubing, stoppered it at the bottom with concrete and sand. The capsule, a cartridge seven and a half feet long, was made of a Westinghouse nickel and silver alloy copper, lined with Pyrex glass, emptied of air, filled with inert nitrogen. Among the objects which went into it were a woman's hat, razor, can opener, fountain pen, pencil, tobacco pouch with zipper, pipe, tobacco, cigarets, camera, eyeglasses, toothbrush; cosmetics, textiles, metals and alloys, coal, building materials, synthetic...
...made it necessary to include several unusual features. Construction is being super-intended by Mr. Herbert E. Hanson of the observatory staff. Except for the polar axis and counterweights, the mounting is of Dowmetal,--probably the first telescope mounting ever made of this specially light and strong magnesium alloy. The Dow Chemical Company, of Midland, Mich., cooperated in providing the difficult castings necessary for both the telescope tube and mounting...
Basic reasons: new alloy steels, vast technical advancement in construction and bridge theory (John Roebling did not even know the theory when he built his World Wonder). A big factor in modern bridge masterpieces is one Engineer John Roebling never heard about: the professional bridge designer and architect. To him must go substantial credit for creating modern bridges which begin to approach in delicate, aerial appearance what bridges have always stood for in men's imagination...
...Bureau of Mines held up pieces of steel and brass, dropped them on the floor. They clanged. Mr. Dean then dropped a piece of another metal. There was a faint thump. This "noiseless" metal, as strong and elastic as mild steel, is a heat-treated alloy of copper and manganese. "This," said Metallurgist Dean, "opens up many new possibilities-chatterless spring suspensions, noiseless gears, a muffler for a whole host of bothersome industrial sounds...
...months ago the Fruehauf brothers got the job of national distributor for the stainless steel trailers of Budd Manufacturing Co., gave an initial order for 10,000 stainless steel semitrailer body sets. On the market and doing nicely is Fruehauf's new light-weight Aerovan (of aluminum alloy) which, carrying a ten-ton payload, weighs three-quarters of a ton less than Fruehauf's equivalent steel model of last year. One growing reason for reducing trailer weights: many a local highway regulation restricts them...
