...Institution). In the "Temple of the Warriors" at Chichenitza, stupendous Mayan ruin in Yucatan, President John Campbell Merriam and Dr. Alfred Vincent Kidder of the Carnegie Institution watched amazed as Earl Morris, their associate on the expedition, scraped away the filth that for centuries had hidden a beautiful mosaic disc containing several hundred pieces of polished turquoise. It had been lying under the carved and painted Mayan altar discovered two years ago and is the "most artistic and elaborate of all known relics of Mayan civilization...
...weak Nichols Club team by a 12-2 score. The contest was played on a very small rink and was marred by rough play on both sides. At no time were the New Yorkers a match for their smoother and faster opponents. The Crimson forward line took the disc up the ice time and again in a beautiful exhibition of coordination and team work. Both forward lines were used and proved equally efficient in driving the puck home. The work of the Crimson defense men was of a similar high grade, the Nichols forwards breaking through for a shot only...
...meeting of the Society of Automotive Engineers at Detroit, C. Francis Jenkins of Washington displayed his "chronoteine [time stretching] camera." It consists of a 13-in. disc holding on its periphery 48 lenses. As the lenses revolve a photographic film moves back of the disc. Normal exposures are 3,200 a second, possible exposures 10,000 a second. (The ordinary cinema camera takes 16 views a second.) Utility: Resolving for leisurely observation the details of swift moving machinery, gun fire, water flow...
Sending Set. This consists of: 1) an arc light of brilliant and steady glow which throws a beam of light through 48 apertures arranged spirally in 2) a large disc that revolves 18 times a second. The light thus brushes speedily across an object or performer and is reflected back upon the third important element of the device-photo-electric cells. The reflected light modifies the electro-magnetic waves passing through the tubes. With light waves rapidly translated into electro-magnetic waves, there remains no problem of sending the electro-magnetic waves through the air. Radio transmission, which changes sound...
Ernst Frederik Werner Alexanderson, mechanical as well as electrical genius, took Mr. Moore's neon tube and made it the heart of television devices on which he had been experimenting for half a dozen years. The rotating disc with its holes arranged in spirals is his, as is the method synchronizing the television sending and receiving sets. Transoceanic radio and radio telephony are possible because he invented the Alexanderson high frequency alternator. To buy that invention and thus to prevent the British Marconi Co. from acquiring it, the Radio Corporation of America was created...
