Lestoil Syndrome. Du Pont had the nylon market to itself for 15 years, and did well with Dacron too. But when it went into production of its tough new Delrin plastic-a breakthrough it considers as important as nylon-hardly two years passed before competing Celanese Corp. hit the market with an almost identical plastic developed by its own chemists. U.S. Steel recently developed a new, economical "thin tin" plate-only to find other steel companies out in six months with a thin tin that customers liked better because it gleamed brighter; Big Steel is now copying some...
...Though sales rose 13% last year to about $16.5 billion, profits of close to 6% on invested capital were three-fifths of the average for all manufacturing. Textile manufacturers are also running into rough competition from such textile substitutes as paper napkins and plastic seat covers, and to an extent suffer from the longer life of synthetic fibers...
...borne scientists photographed the ancient vessel from above by swimming over it with underwater cameras-a preliminary process already reported in the National Geographic. They marked the crust of lime that covered the remains and carefully chiseled it into chunks that were lifted 3 to the surface by inflated plastic balloons. Bit by bit the wreck was moved ashore and reassembled...
Below the gossamer-thin plastic bag that climbed over Palestine, Texas, dangled a 6,300-lb. L-shaped package as bulky as two Cadillacs. It was surely one of the most ungainly-looking loads ever hefted aloft. Designed and built by PerkinElmer Corp. of Norwalk, Conn., it contained a 36-in. mirror that would be a respectable size even for a solid-ground observatory, but that mirror was only the beginning. The telescope was suspended so that it could swing in all directions, under precise control by ground radio. It carried a coarse-vision television camera...
Spread over miles of desert near Albuquerque, shallow disks of special plastic material bake in the sun. Connected by wire to a central laboratory, they are scintillometers set out to watch for enormously powerful cosmic rays that smack into atoms in the high atmosphere and, as a result of the crash, spray the earth's surface with millions of subatomic particles. Despite the minute size of his quarry, Physicist John Linsley of M.I.T., who operates the ray trap, reported a tremendous catch: a shower of 50 billion particles...
