Rotating Vats. The crucible of the furnace is located inside a smaller f-shaped building near the base of the big mirror. It is set behind large stainless-steel doors at the focal point of the parabola-where the sun's scorching rays are concentrated into a blazing circle only twelve inches wide. Target material, hoisted into place by a ten-ton lift, is placed into an inclined trough-as the target melts, it runs off into catch pans. Another, more sophisticated technique is to load the material into two aluminum vats whose outer walls are water-cooled...
Unsterile Needles. Metals are still harder to deal with, especially the 1.2 billion disposable stainless steel needles attached to plastic syringes that are now used each year in the U.S. Of this total, nearly 800 million are used in hospitals, almost 200 million by diabetics giving themselves insulin, as many more by doctors and nurses in their offices, and the remainder by nursing homes, researchers and veterinarians...
Behind His Back. When a hip joint is damaged, the ball of bone at the head of the femur may rub against the roughened surface of the socket in the hip proper (see diagram), causing severe and immobilizing pain. Replacing the head of the femur with a stainless steel ball (just under an inch in diameter for the average patient) is relatively easy. The difficulty is to secure the ball to the femur. In early operations, the shaft holding the ball was screwed into the femur. Charnley was dissatisfied with the method because the shaft sometimes came loose. A dentist...
When she first streaked across the plains 21 years ago, the California Zephyr was a gleaming wonder-on-wheels. The first luxury Vista-Dome streamliner to run between Chicago and San Francisco, the stainless-steel train topped 90 m.p.h. on the straightaway, dazzling onlookers at every wayside crossing. Last week the Cal Zephyr, rattling from disrepair and more than 6,000,000 miles of wear, made its through-run for the last time. Latest victim of rising costs, declining patronage and the reluctance of railroads to promote passenger service, the train was, as one member of the Interstate Commerce Commission...
...International Nickel Co., the world's largest producer, followed an expensive settlement of a 128-day strike at its Ontario mines by announcing a 24% price increase. The move is bound to have major effects in the U.S. Stainless-steel producers, who use 37% of all nickel, are expected to increase prices shortly, for the third time since January. From nickel-plated auto bumpers to jet engines, many products are sure to cost more...
