...earth. As soon as SNAP's scientists were convinced that the proper orbit had been attained, they sent a signal that told the reflector mechanism to reduce neutron leakage. Slowly the nuclear reaction started; heat built up in the core, and a magnetic pump circulated the metallic coolant at 1020°F. through tubes in the skin of the support structure. The inner ends of 2880 pellets of a germanium-silicon material were heated while their outer ends were kept comparatively cool by heat radiation into space. The germanium-silicon combination is "thermoelectric," it changes heat to electricity...
...adventurous surgeons have devised still other ulcer treatments. From the fertile mind of Minnesota's Wangensteen came the idea that chilling the stomach, by running a coolant solution through a swallowed balloon, might stop bleeding from ulcers in the stomach itself. It did. Then with his surgeon son Stephen, Dr. Wangensteen reasoned that actually freezing the stomach wall might cripple the acid-producing cells and thus keep acid from spilling into the duodenum. It does, at least for several months. After that, says Dr. Wangensteen, the procedure can be repeated-though in any but expert hands...
...alcohol coolant is run through the balloon for an hour. Then, after five minutes for thawing, the balloon is pulled out. The patient can get up at once and leave the hospital or clinic. Within two hours he can eat a hearty meal...
...exhaust pipes. To differentiate it from the standard Pontiacs. which have new prow-shaped grilles, the Grand Prix grille is split by a vertical wedge. Like most 1962 cars, Pontiacs have such improved maintenance features as 35.000-mile chassis-lubrication intervals, 4.000-mile oil changes and two-year radiator coolant...
...safe" device known to science. What went wrong with SL-1? Although technicians could stay in the building for only brief periods, everything they saw suggested that the impossible had happened: the reactor had suddenly boiled up in a runaway atomic reaction. In thousandths of a second, its water coolant had been turned into superheated steam that ruptured the reactor tank. Best guess was that some of the cadmium control rods (which are inserted to stop the nuclear reaction) had somehow been lifted out of position...
