Weinberger of Ottawa once shielded himself with a sheet of nylon and let a Canadian soldier jab at him with a bayonet. Anyone would have thought him mad. But the bayonet scarcely dented the fabric...
Weinberger is the proud inventor of a new nylon "body armor" - a 1/8-in.-thick fabric that holds great promise for wide use in war, law enforcement and industry. According to Davis Air craft Products Inc., the Long Island firm which is producing and developing it, the material is 48% more effective than any armor now in use. "The difference between this material and other nylon fabrics is primarily a matter of weave," says Weinberger, who is keeping the pattern a secret until his patent is granted. "It works by diverting the impact energy from the impact point." Threads...
...Manned Spacecraft Center, the lifeboat is a rigid 400-lb. fiber glass shell lined with polyurethane foam and shaped like an old French bathtub-narrower at one end than at the other. It is 6 ft. long, 4| ft. wide, 21 ft. deep. Sheathed in a Johnson-designed nylon heat shield for re-entry into the earth's atmosphere, the craft is equipped with a swivel-mounted retrorocket, attitude-control jets, a transponder for ground control, a built-in oxygen supply, a parachute and a survival kit. Johnson envisions a typical Apollo spacecraft as carrying three such lifeboats...
...will be usable only on near-earth orbits. Even so, work on it has progressed further than on any other rescue system. Small-scale models have been repeatedly drop-tested in laboratory experiments. Computerized simulations of re-entry have uncovered potential flaws that are being corrected; Johnson's nylon heat shield has stood up well under rigorous tests at NASA's Langley Research Center. Next step: drop tests of the full-size boat in the earth's atmosphere, and then an unmanned test in space...
Bellis and other scientists think that the moving nylon filaments jog the minute fog particles together, causing them to combine into water droplets large enough to drip down the threads. To test the brooms outside the laboratory, the New Jersey researchers have set up 20 in a field outside Trenton and equipped them with photoelectric devices that start their motors when a fog settles in. If they effectively clear a corridor through the fog, the devices will probably first be placed in operation along a stretch of highway five miles west of the Lincoln Tunnel that is frequently shrouded...
