High Speed Protons. An apparatus for accelerating the motion of protons until they race along at 37,000 mi. per sec. has been successfully tested, explained Dr. Ernest Orlando Lawrence, physicist at the University of California. The new method does not involve the difficult high voltages which have been thought necessary in producing high speed sub-atomic projectiles. Protons (hydrogen atoms stripped of their electrons) are sent back and forth between two semicircular hollow plates by means of alternating currents of 10,000 volts and a magnetic field. As they continue in a spiral motion they gather speed, finally shoot...
...After a few test runs in daily papers, last week Ex-Lax ("the safe laxative that tastes like chocolate") advertising was started on a national magazine campaign. Simple in form, it consisted of an endorsement, a picture of the endorser, a few remarks by the company, a free sample offer. Its appeal lay wholly in the endorser: Charles ("Chic") Sale, author of The Specialist and I'll Tell...
...vaudeville monologist (opens next week in Hello Paris, at Newark, N. J.), found "The Specialist" one of his best acts, wrote it down hoping to sell a few books to friends (TIME, Aug. 26, 1929). When not trouping he lives in Scarsdale, N. Y., with his three daughters. Test copies of the new Ex-Lax campaign included the straw-munching Specialist's accounts of a rural traffic policeman who took Ex-Lax, be- came healthy, smiled so much he was made an official; the yarn of a dentist who did no business, gave Ex-Lax away, made people so healthy...
Unprecedented, this ruling whipped up a squall of protest. The Aeronautical Chamber of Commerce called in William Patterson MacCracken Jr., chairman of its legal committee, demanded a hearing before the board. There was talk of a test case in court. Manufacturers?particularly of seaplanes and amphibians?were incredulous. Their whole appeal to the private flyer, upon whom they depend for much of their business, is based on the inducement of flying between city and vacation camp where lakes furnish easy, safe landing places without cost. Such lakes abound in New Jersey...
...which prevent undue acidity. The great work of filtration is done by a tank containing 27 tons of graded Cape May, New Jersey sand, through which the water will seep. Before entering the pool it will be impregnated with chlorine gas, which lends a greenish color. The results are tested twice daily by comparing a test-tube full of water with a graded color chart. In addition the floor of the tank will be periodically subjected to the suction of a large curry comb, connected by a hose to the vacuum end of the pumps...
