...Welding Retinas. Taking advantage of the unerring straightness and narrow diameter of laser beams, engineers are already using them to keep bridges, tunnels and dams in line during construction. Laser light has also proved helpful in aligning jet-plane assembly operations and the two-mile-long Stanford linear accelerator. When the high energy of laser light is concentrated on a small area, it serves as a high-speed drill that can burn precision holes through materials as hard as diamonds in a small fraction of the time required by conventional methods. It can vaporize the rough edges of such microscopically...
...does not draw blood. Its searing but highly localized heat cauterizes capillaries and other blood vessels as they are severed. Like ordinary light, laser beams pass through transparent substances but are absorbed by darker, opaque materials. Thus they flash harmlessly through the cornea and lens of the eyeball to weld a detached retina back into place, or puncture small holes in the retina to ease the pressure of glaucoma. They also penetrate translucent skin to vaporize skin cancers, or tattoos that out-live the patient's enthusiasm for such decoration. Lasers are being used in data pro- cessing...
...said one dealer whose entire switchboard lit up at once. "We just pulled all the cords out and started fresh." Other brokers encountered long delays reaching marketmakers. Such tie-ups often hurt investors, as prices rise before their orders can be placed. Goodbody & Co. stopped giving quotations and White, Weld & Co. halted its over-the-counter operations an hour before the new and foreshortened 3:30 p.m. official closing time. Despite all the activity, most indexes showed that stock prices fell slightly last week; the Dow-Jones industrial average slipped 1.26 points to close at 913.62. Many brokers dismissed...
Then on May 7, only hours after he had turned in the second fastest lap in Speedway history. Mike Spence was killed in a freak accident while testing teammate Greg Weld's turbine. The next day Weld, who had been slow all month, was released by STP, and Granatelli was left with 1966 winner Graham Hill, and four turbine cars...
George Guild was the Weld workhorse. He ran the 100 in 10.2 and anchored the winning Weld North relay team to take double wins on Friday...
