Fultograph in" Australia RRANGEMENTS are well in hand for the transmission of "stil * nic. ’ tures by the Fultograph method from 2¥C, Sydney, and 38L0, Melbourne. The engineering work is well advanced, and transmission will begin as soon as business details are arranged. The company responsible for the in-: novation has a limited quantity of re- * ceiving apparatus available for the use: of experimenters, and the demand which was set up in Britain for Fultograph receivers as soon as the B.B.C. began transmitting pictures, should be repeated in Australia. Any object that is capable of being photographed can be transmitted and received under the Fultograph system. Ordinary events of the day, sectious of newspapers, typewritten docu-’ ments, and business contracts can all be transmitted. Should the police wish to transmit a photograph or the finger-prints of a "wanted" person, it can be put on the air and transmitted throughout Australia within five or ,ten minutes, . _No dark room or developing apparatus is needed at the receiving end. The photograph as printed by the receiving apparatus is a permanent photograph, The receiving apparatus ‘takes the place of the loudspeaker. At the studio there is attached to the transmitting apparatus the developed negative of a ’ photégraph. A powerful beam of light is focused upon the photographic plate, the amount of light being regulated by the varying intensity of the negative. The photo-electric cell controls the signals transmitted. These in turii regulate the stylus pei that prints the photograph on the receiver. The synchronisation of the transmitter and .. receiver is arranged by a number of clutches on the receiver which are operated by synchronising signals from the transmitter. , . , No price has been fixed for the receiving apparatus to Australia, but it is estimated to be less than £40.
