To triple the voice-carrying capacity of coaxial cable, Bell Laboratories engineers had to create new amplifying tubes with the grid placed only two-thirds of a hairs breadth from the cathode. Furthermore, the grid wires had to be held rigidly in position; one-quarter of a hairs shifting would cut amplification in half.
Nowâ€”from RCA, pioneer and world leader in electronic research, come two great new electron microscopes. The EMU-3A with both 50,000 and 100,000 volt accelerating potential is destined to be recognized as perfection in electron microscopy â€”the ideal tool for advanced research requiring highest resolution, maximum magnification and critical control. The EML-1A, a 50,000 volt instrument, has every important feature needed for peak performance in a wide range of research and control functions.
meet a “flyer” with over 250,000,000 hours behind him! “He’s” a new Lycoming air-cooled engine. He’s backed by Lycoming’s experience in creating and producing – 50,000 aircraft power plants . . . each with a flight-proved life expectancy of at least 5,000 hours. You learn a lot about flying in 25 years . . . […]
