...converter is made of two plates of tungsten that are a fraction of a millimeter apart. Between them is a vapor in near vacuum. The plates are so treated that they have different electric potentials. (G.E. will disclose neither the vapor nor the method of treating the plates.) The plate with the higher potential is heated to about 1,500° centigrade, the other to around 1,000° centigrade. The first plate is hot enough to release electrons; the second is not. Clouds of electrons boil off the hotter plate (the cathode) and are attracted to the cooler plate...
...officially Premier, intended originally to steer a noncommittally neutral course between East and West. He still may, but lately, possibly because the U.S. and France have been delivering their $55 million in development aid on schedule while the Chinese Communists have made good on just a fraction of the $22.9 million worth of cement, steel and textile shipments promised for 1957, his press has been outspokenly antiCommunist, and Cambodia has been voting more and more with...
...home. Originally designed for the palaces of the rich, it now makes ideal hi-fi listening, but for years American record buyers ignored the fact, turned the volume up and delightedly let the high decibels of opera and symphony beat them down. Chamber music accounts for only a small fraction of U.S. classical record sales, but there are some signs that the situation may be changing...
...sufficient intensity to damage them. The four beams came to a sharp focus at the exact part of the ansa lenticularis on the left side (controlling right-side movements) that Dr. Meyers wanted to destroy. The ultrasound dose lasted only 1.8 seconds. The patient was moved twice, a minute fraction of an inch, so that two more pinhead-size parts of the ansa lenticularis were destroyed...
...that after a few days the patients stopped responding to the treatment and soon relapsed into their former state. Harvard University's Dr. Mark D. Altschule guessed that this was because of big beef protein molecules in the extract. He set himself the job of isolating the potent fraction in the pineal glands from this kind of protein...
