The international photographer (Jan-Dec 1936)

January, 1936 I 1 1 INTERNATIONAL PHOTOGRAPHER Thirteen consists chiefly of the Iconoscope, invented by Zworykin in America. This method is a combination of a photo cell and a Cathode Ray Tube: an image is focused on to a mosaic photo-electric plate, charging the minute cells which in turn are discharged by a Cathode Ray Beam. The discharged current is collected on a positive metal anode, this current is the Television Signal and is now amplified. The Iconoscope is used in the same manner as the Farnsworth Electron Camera for Telecine or direct pick-up. Reception All the leading radio manufacturers will be marketing receivers that will be capable of receiving both systems. Most of these receivers will utilize the Cathode Ray Tube for picture reception; picture size will vary from 5" x 6" to 14" x 16". The cost of the receivers will range from $130 to $500. The largest receiver will be no larger than a large Console Radio. Programs There is no definite proposal as to the type of programs that may be expected. But this is a rough guess: The major part will be in the form of films, with vaudeville and talks from the direct pick-up methods. I do not think, that much will be done in the way of play production until Television has established itself as a definite entertainment. Big Screen Television in Cinemas The Baird Company has two methods for big screen work: 1. Intermediate Film Projection. The Television Image is received on a Cathode Ray Tube and is rephotographed by means of a continuous camera. The film is developed and then projected on to the screen in the space of 2 minutes. Although this method is in its infancy, it shows great promise. Some film that was taken by this method was shown at the Cinema Exhibitors Association, at Cardiff, this year, making a good impression on those that saw it. It proved that Television could be used in cinemas for more than a novelty and that for important topical events it would be a definite asset. 2. High Speed Mirror Drum. In this method the Television Signal modulates a Kerr cell which allows a varying amount of light to fall on a High Speed Drum which throws the image on the screen. This method of big screen Television is being installed at a London Theatre where it will be publicly demonstrated in the near future. It has been stated that the Scophony Television Company, of England, have perfected a big screen Television Method, but to date no details have been published. This is the fairly advanced state in which Television finds itself in England. Everybody is awaiting 1936 when Television transmissions start in earnest. HOLLYWOOD TO JAPAN Art Reeves reports the shipping to Japan, recently, of one of his latest type developing machines which was billed to the Yokohama Cinema Company. The shipment was accompanied by a varied assortment of other laboratory equipment. "SPEAKING PAPER" DEMONSTRATED IN LONDON "Speaking paper," an invention of an Argentine engineer, was recently demonstrated in London, according to a report from the American consulategeneral, London, made public by the Commerce Department. By means of this paper, it is possible to present a record of speech, music or any other sound in as handy a form as the daily newspaper. It is claimed that the invention will create a new industry, which will produce "speaking" books, sell the equivalent of 12-inch graphophone records and will also permit newspapers to print an actual record of a public speech, concert or play which readers could reproduce in their own homes, the report states. The system, called the Fotoliptofono, works more or less on the principles of a talking picture. A sound track is registered on a celluloid negative by means of a microphone and oscillograph. From this photographic impression a block is made from which is printed the "speaking paper," a series of close parallels of jagged black lines, it was stated. The paper is then placed in the reproducing apparatus, the subject of the recent demonstration. A piece of paper about the size of a single newspaper sheet was fitted on to the cylinder of a machine resembling the early Edison phonograph and a photoelectric cell retranslated the black lines into impulses which issued from an ordinary portable wireless set as speech, song and music in turn, according to the report. It is reported that negotiations are in progress looking to the production of the "speaking paper" by the English graphophone companies.
