WIRELESS PHOTOS

MUCH PROGRESS MADE A SUCCESSFUL DEMONSTRATION, AN INGENIOFS APPARATUS. PARIS, Dec. 21. In order to demonstrate tje ad vancod state of the television invoution. _M, Belin transmitted a photograph of the president of the Society of Photographers successfully. The pri?uipal component of his machine is a. multiflared mirror mounted on a vertical steel disc. The image to be transmitted is placed between high-powered electric arc lamps, and the mirror which revolves at a speed of 4000 revolutions per minutes conducts the light through the wireless transformer. The. ingeni ous two-way motion of the. apparatus enables flash lights to bp. picked up ’at. the receiving stations after its journey through space and the mystery coils of Al. Belin’s invention. NOT FOR TEN YEARS WIRELESS INSUFFICIENTLY SELECTIVE LONDON, Dec. 20. The. Paris correspondent of the 4 ‘Weekly Dispatch’’ says that Edward Belin gave a demonstration of his tele vision invention in which he uses a photo telegraphic tuning mirror. Professor Low, who patented the television apparatus during the war period, explains that the principle of television consists of dividing a picture into small squares which are transmitted independently at a speed enabling tho second impression of the whole picture to begin before the first has faded from the eye. This is al. present impossible because wireless is insuflirient ly selective, to enable the use of Hip different wave lengths which are essential When selective wireless permits simultaneous transmission of whole pictures, eliminating the tuning mirror the problem will be solved. That is unlikeIv for at least 19 vears.
