Above $200 you enter the relm of racing bikes. These machines come close to the ultimate in light weight and performance. The frames are handmade of special alloy tubing, the tires are known as sew-ups, (very light with the tubes sewn inside). Having the tubes sewn inside makes them a real pain to patch, but there is no other way of making a tire as light (often less than 200 grams per tire) or as strong (racers ride with tire pressures well over 100 pounds per square inch), or as easy to change. While a bicycle like this...
...have predicted that the lowly copper penny would one day be priced out of the market? Alas, that day is at hand, and the Senate last week passed a bill, proposed by the Department of the Treasury, that would allow production of a new penny made of 96% aluminum alloy. The Treasury's problem: the copper used in minting billions of pennies annually is growing prohibitively expensive. Last January, the world price of copper was 50? per Ib. Now the price is more than $1 per Ib. and, the Treasury Department notes, if that figure reaches $ 1.20, the cost...
Both correspondents found that the many East Germans they interviewed outside Berlin were friendlier-and far more talkative-than the uptight "press officers" in the capital. "Sometimes it was difficult to break away from their exemplary hospitality," says Nelan, who endured a four-hour tour of an alloy steel mill. Rademaekers met with more warmth than he had bargained for. "A heat wave was sweeping across East Germany," he complains, "and every window seemed locked up for the winter...
...Koma Kyuhaku's 18th century inro are complemented by a fierce little demon mask with ivory horns. In a sense, the extreme limit of aestheticization was reached by the makers of tsubas. Considered merely as an object, the 19th century sword guard of the blue-black copper alloy known as shakudo, inlaid with gold maple leaves (the gold patchy, as in autumn), is sumptuous enough. But the idea of dying with so delicate a work of art attached to one's stomach by two feet of razor-sharp steel could only have arisen in Edo Japan. ·Robert...
...Carpenter Technology Corp. and the Wolverine Tube division of Universal Oil Products Co. to turn out high quality zirconium and stainless steel tubing under a Soviet process. At the moment. Patent Management is offering rights to a Russian electroslag refining process that is used to produce high-quality alloy steels. Noting that the Russians are usually eager to acquire American expertise for their industries, Patent Management's General Manager Clifton Hilderley admits that peddling Soviet patents in the U.S. is "something of a switcheroo." Though the Soviets want to sell in the West in order to acquire currency, they...
