...that basic question, the experts discovered that the bullet-marking characteristics of Sirhan's Iver Johnson .22-cal. revolver had changed since the night it was fired in the Ambassador Hotel. The panel found that the inside of the barrel was fouled by a thin layer of copper alloy that probably stemmed from test firings by the Los Angeles police. The panel squeezed off eight shots into a tank of water, compared the bullets with the original three, studied the barrel of Sirhan's gun, and finally gave up. They announced that they could not say for sure...
...Pain. Developed by Dr. Theodore Waugh, 48, an orthopedic surgeon at the University of California at Irvine (U.C.I.), the new joint is a two-piece arrangement that weighs only five ounces. One part of Waugh's "U.C.I, ankle" is an inverted T made of a chromium and cobalt alloy with a concave tip. The other part is an alloy half dome...
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...
