...Electron Cutter. United Aircraft Corp.'s Hamilton Standard Division (propellers) will put on the market a machine, developed by West Germany's Carl Zeiss Foundation, that uses electron beams to weld, mill and drill hair-fine holes in the hardest known materials, e.g., quartz, tungsten, zirconium. An electron gun fires beams that boost the temperature on the surface of the material up to 11,000° F. ; it can cut 100 holes in a straight line across a pinhead, drill a sapphire watch bearing in six seconds, weld a tough nu clear reactor core. Lease price: about...
Through the use of the electron microscope and X-ray microscopy, scientists at the School of Dental Medicine have observed the nature of certain dental tissue changes which give a fairly accurate estimate of an individual's age by examination of single teeth...
According to John Nalbandian, research fellow in dental medicine, the study centered on changes in the degree of transparency in the dentin or solid portion of the root of the tooth. When examined beneath the electron microscope, thin sections of dentin showed an accumulation of minerals from which the age of the individual could be determined within an accuracy range of 7.9 years...
...world's most powerful atom smasher is in neither the U.S. nor in Russia; it is in Switzerland. In the rolling countryside three miles northwest of Geneva, the European Council for Nuclear Research (CERN) has built a great new proton synchrotron designed to produce 25 billion electron volts. Half buried in a hillside, it is a huge doughnut of magnet steel, 656 ft. in outside diameter. Last week British Physicist John B. Adams, chief of CERN's Proton Synchrotron Division, ordered slight corrections in the magnetic field, watched as the protons sped faster and faster around their circular...
...Holland, 114,000 in the rest of the world. It thus rates after General Electric as the largest employer in its field, generates 12% of Holland's industrial export income by turning out scores of products including Christmas tree lights, Norelco electric shavers, television sets, super-powered electron microscopes, hospital equipment and musical recordings. At the drop of an order, the company can overhaul a complete national telephone system, as it did for Argentina, build a 160 million-volt cyclotron, as it did for the University of Paris, or light and wire for sound the Acropolis in Athens...
