...rocket with a special camera. Fired from the White Sands missile range in New Mexico, the rocket soared through the atmosphere; 123 miles up, the camera began clicking. The camera was fitted with a mirror ruled with a grating of fine lines, 15,000 to the inch, designed to filter out the sun's glaring visible light, which otherwise would have overwhelmed the Lyman-alpha rays given off by the clouds. To keep the camera stabilized in the nose of the yawing rocket, University of Colorado physicists had devised a highly sophisticated motor-operated mount, equipped with photoelectric cells...
...nearly 3½ days the delicate radio signal came bravely down from space. At last it faltered. The Jet Propulsion Laboratory's 85-ft. antenna at Goldstone Dry Lake, Calif, changed to a special filter and held the signal for a few minutes more. A receiver of General Electric's at Schenectady, N.Y. heard the signal intermittently for about an hour longer. Then it faded out. Some 410,000 miles away in outer space, Pioneer IV, the U.S.'s first man-made planet, wheeled on around the sun, but now silent forever...
Designed by Surgeons Claude R. Hitchcock and Joseph Kiser of Minneapolis General Hospital, the mask is made of flexible polyvinyl plastic. Inside it is a disposable filter of cotton and cellulose. In this trap the surgeon's breath is both dried and filtered; the exhaled air escapes backward from the mask's wings, is almost germfree. The new mask, built to stand away from the skin, is cooler than the close-fitting, clammy gauze. And although the plastic part costs $1.50, it should save hospitals money in the long run because it can be sterilized and reused...
...human kidney is a filter capable of such fine chemical discrimination that no machine yet visualized can come near matching it. But with uncommon ingenuity and commonplace materials, researchers have produced an effective stand-in which does its most obvious and important jobs. Head and shoulders above other kidney makers is tall, tart Willem Johan Kolff, 48, of the Cleveland Clinic. Physician Kolff made his gadgeteering breakthrough in his native Netherlands during the Nazi occupation...
...probably will want three, four or even five years from now." Putting his precept into practice when he took over P. Lorillard Co. 2½years ago, Chairman Lewis Gruber, 63, rescued his aged (founded 1760), slipping company by gambling heavily on smokers' future desires. He changed the filter and blend of Kent cigarettes to cut down tar and nicotine and -as he says in the kind of phrase that sounds snappy around a boardroom table -give smokers "less of the things they have been smoking filters to get less of." Result, in the statistics that look wonderful...
