...satellites, which he prefers to call a sub-satellite, is so light that it can be carried almost as an afterthought by any orbit-bound rocket. It is a balloon of plastic film .00025 in. thick, bonded to aluminum foil .0005 in. thick and packed in a doughnut-shaped container. To inflate the balloon, O'Sullivan provides a capsule of nitrogen gas at 2,000 Ibs. pressure per square inch. The whole apparatus weighs only...
...abdominal flesh to the wrist, and the patient kept his arm in place for three weeks while the graft took. The next stage was tougher: the graft was cut loose from the abdomen, and the arm was laid across the drawn-up right foot. Again, the same commands. After plastic surgery under a light analgesic, the patient held this grotesque position for four weeks without complaint. He could even feed and bathe himself, walk with one crutch. The four weeks over, the graft had taken on the foot. Barron cut it loose, and Kelsey gave the order: "Unlock...
...cloth velarium used by Roman emperors to cover the Colosseum, Stone found his solution to roofing the largest free-span circular building ever erected. He devised a bicycle-wheel system of cables, each under no tons' tension, to hold up the pavilion's 68,400 sq. ft. plastic outer roof...
...tension ring 63 ft. across and weighing 25 tons, is dramatically suspended in midair and open to the sky above the central pool. To give the structure the maximum look of lightness, a trellis of light steel straps was used to hold the 42-ft.-high plastic walls rigid against the wind. Says Stone: "I'm not given to flexing my structural muscles publicly. But you can't say this building doesn't shout with steel. Why, you can almost hear those cables, and you can see every damned member...
Astrolite cannot resist continuous high temperature (the plastic binder melts at about 450° F.), but it is remarkably successful against short attacks of extreme heat. It is used in 20 types of missiles, sometimes in the nose cones, sometimes in other hot spots such as the nozzles of rocket motors. The Thompson company says that a laminated layer of Astro-lite two-tenths of an inch thick can protect the nose of an IRBM. For an ICBM, which enters the atmosphere much faster, four inches may be needed. This thickness weighs, says Thompson, only one-fifteenth as much...
