...device--a so-called "fiber optics instrument"--consists of a long thin tube that is inserted into the heart. The tube is made of a bundle of 70,000 glass fibers which transmit an image from the inserted end to the viewer...
...clubs for Christmas-clubs with aluminum shafts. Like the steel tennis racket, the aluminum-shafted golf club is being touted as a breakthrough of science. For 15 years, club manufacturers have been trying unsuccessfully to improve on the now-familiar stepped steel shafts that replaced hickory in the 1920s. Fiber-glass shafts, for instance, are whippier than steel, but their extreme flexibility only tends to exaggerate flaws in a golfer's swing. Aluminum is more rigid than fiber glass, and lighter than steel. The lighter shaft allows manufacturers to put more weight into the club head. The result...
...vision. Hartline, 63, a professor at New York's Rockefeller University, has traced the patterns of nerve responses after light touches the retina's receptors. Using horseshoe crabs, which have relatively simple eyes, and frogs, he recorded the electrical signals sent out by a single nerve fiber, learned the neural influences of one receptor cell on another. "We listened in," he explains, "on the small traffic signals in the body of the crab...
Convinced that the time has come to overhaul its antiquated and uncomfortable system, New York City's Transit Authority recently announced a $5,800,000, six-station renovation program. It has also begun experimenting with air-conditioned, sound-proofed cars with fiber glass molded seats and hopes to cut down noise by laying rubber cushioning between the tracks and roadbed and by replacing short sections of track with longer, welded ones...
...seater Excalibur, custom-made in Milwaukee, is a fiber-glass replica of the 1927-29 Mercedes-Benz SSK, fitted onto a Studebaker Cruiser chas sis and propelled by a 350-h.p. Corvette engine. Sonny's model set him back about $10,000, which is cheap considering that the Excalibur is the car-of-the-month in Hollywood, and that, furthermore, owning the car-of-the-month wins nearly as many prestige points these days as punching Frank Sinatra in the gush...
