During the six-month austral, or southern, summer, when the South Pole is bathed in sunlight 24 hours a day, geologists from the U.S., Australia and New Zealand explored the rocky mountains of Northern Victoria Land. They found signs of such valuable metals as tantalum and lithium, used for making high-strength alloys. The Dufek Massif in the Pensacola Mountains, similar to South Africa's Bushveld, may have platinum and chromium, both strategic metals...
Much technological wizardry went into the Disc. Unlike other consumer-oriented cameras that use optically undistinguished lenses, the Disc lens is made of four glass elements that Kodak claims are "close to theoretical perfection." The camera's electronics and flash systems are powered by a new lithium battery that lasts for 2,000 exposures, easily the life of the camera. Most revolutionary of all is the revolving film pack. The new cameras use a thin, 2½-in. -diameter plastic disc that is priced at $3.19. The disc slips into the camera's hatched back and is turned...
...scientists at Johns Hopkins University and Sinai Hospital of Baltimore developed a small device called an automatic implantable defibrillator. This is placed in the abdomen and has electrodes that are connected to the heart's right atrium and to the ventricles' pointed tip. It is powered by lithium batteries good for three years or 100 shocks. Says Hopkins Cardiologist Myron Weisfeldt: "When the patient has an arrhythmia persisting for at least ten seconds, the machine waits another five seconds and then discharges an electric shock, which usually stops the arrhythmia...
Portables can be quite sophisticated. One unit is not only AM/FM but is equipped with a liquid crystal diode (LCD) digital clock. A separate lithium battery with a service life of one year is used for the clock and three AA pen-light batteries for the radio. The clock is equipped with a beep wake-up alarm that will run for about four minutes after the selected alarm time has been reached and it will then turn off automatically. Unlike analog clocks, the digital in the radio has an AM and PM indicator. The clock has an hour switch, minute...
...severe aberrations in beat, and within 15 to 20 seconds administers a corrective shock (700 volts) that a conscious patient feels as a sharp tingle. If the heart does not resume normal beating, the defibrillator commands up to three more jolts. During the three-year life of its lithium batteries, it would be able to provide as many as 100 shocks...
