With the only refrigerated wind tunnel and the biggest low-pressure chamber in the U.S. aviation industry, Airesearch Co. of Inglewood, Calif. is developing equipment to send planes toward the stratosphere, whither the air battles of World War II are rapidly climbing. The refrigerated wind tunnel, an enormous doughnut 25 feet across, made of tubing three feet in diameter, contains a 300-m.p.h. wind that blows at temperatures down to -90° Fahrenheit...
...heart of the betatron," explains Inventor Kerst, "is a doughnut-shaped glass vacuum tube between the poles of a large electromagnet" (see cut). Inside the tube, a hot filament gives off electrons. Magnetically guided, each electron circles about the tube 400,000 times, accelerated at each rotation by small 70-volt kicks whose cumulative push gives the particle an energy of 20,000,000 volts within a fraction of a second. These fiercely energized electrons are then either: 1) Released continuously from the tube as a beam of beta rays-whence the betatron's name-which...
...through a straight vacuum tube at a target from which X-rays are emitted. Now, in effect, the betatron combines transformer and vacuum tube. Instead of circling round & round a magnet in a coil of wire, as in a transformer, the electrons whirl through the empty space inside the doughnut-shaped vacuum while their voltage increases...
Although Whistling is Comic Skelton's first starring performance, it is by no means his best. His masterpiece is on ice at M.G.M. Made a year or so ago as a screen test, it turned out so slaphappily (mainly because of its doughnut-dunking sequence) that down-in-the-mouth producers, directors and such at the studio are forever running it off when they need some laughs...
Franklin Roosevelt-who had been tipped off by radio to the reception that awaited him-sat still, calm, relaxed, happy; his hair slicked back, black doughnut circles gone from his eyes. He wore loose grey tweeds, a light blue shirt, striped blue-on-blue tie, gold collar pin. Sallow Harry Hopkins sat near by against the wardroom's green-grey bulkhead, eyes narrowed watchfully except when he twitched a smile at a face he knew. From the table's green felt top the President picked a Camel, lit it, stuffed it with his thick awkward fingers into...
