...presence in the East Room of the White House. Already set up was what the journalists have dubbed the "people eater"-a television camera, set almost eye-to-nose in front of the President, with teleprompting devices attached. Above the President's head was an umbrellalike aluminum reflector into which the flood lights were focused. The idea was to protect the President's eyes, and to help erase the worry lines from his face. As it turned out, he looked fine...
...flashbulbs that have to be coaxed into the camera's flash gun before every photograph. Now Sylvania and Kodak have developed a neat solution-the Sylvania flashcube, which is no larger than an ice cube and contains four miniature flash bulbs, each with its own built-in reflector. Packaged in threes for $1.95, the plastic-coated cube fits any of eight newly designed Kodak cameras, completely eliminates the need for the old flash attachment. On cameras with automatic film advancers, the cube spins around so fast the photographer can shoot four times in five seconds-plenty of time...
...fuel is mixed with zirconium hydride, which acts as a moderator, slowing down the high-energy neutrons released by fissioning atoms of U 235. The heat of the reactor is carried away by a sodium-potassium alloy (NaK) that turns to liquid at 48°F. A beryllium reflector 2½ in. thick bounces escaping neutrons back into the uranium and keeps the reactor operating. When four openings in the reflector are uncovered, neutrons leak away, slowing or stopping the nuclear reaction...
This weird and dangerous gadget, weighing 250 lbs., was gingerly set on the nose of an Air Force Atlas-Agena rocket at Vandenberg Air Force Base, Calif. The reflector ports were open to keep the nuclear action from starting, and a conical windscreen covered the reactor to protect it from buffeting as it climbed swiftly through dense, low-altitude...
When the rocket cleared the atmosphere, the windscreen was jettisoned; the reactor and its conical support section went into orbit 800 miles above the 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...
