PHOTOS BY WIRELESS

[ TRIALS IN AUSTRALIA. REMARKABLE INVENTION. ’ ■ . ' Sydney, July 4. '•‘Tap-lap-tap.” Without fuss, ami with even less noise than a typewriter, it is possible to transmit a photograph' across space. The wonder apparatus, the Fultograph, which makes this possible, has been demonstrated with great success in Sydney and Melbourne, under the auspices of the Amalgamated Wire-/ less (Australasia), Limited. Soon it will be tested between the two cities/ and it is feared that it will make obso-/ lete the picturegram service about to be' inaugurated by tho Post and Telegraph;. Department, by which it will be possible:/ to transmit pictures and tho like over. tho telegraph wires. The Fultograph is capable of transmitting photographs, printed news items,-finger-prints—in fact, anything that can be photographed. The transmission can; be effected either by telephone lino ; or by wireless. A notable feature of tho process is the simplicity of reception. Even a boy, it is claimed, can satisfactorily operate the receiving end. . Tho apparatus consists of a cell transmitter and a receiver. When/ photographs are transmitted by radio? the receiver is connected to the sama terminals of the radio set as tho loudspeaker. Another interesting point is that all; signals denoting that the photograph-is G being transmitted come through the loud--speaker as audible sounds. The :actual g process is that a film negative is pro- / pared from the desired photograph and is wrapped round the glass cylinder of , z the transmitter. By means of the photo<« electric cell varying currents according ' to the light and shade of the negative A aro sent out and picked up by the receivcr, either in the same room or hun-G' deeds of miles away. The .receiver also has a cylinder, which is wrapped a paper that has dipped in a solution of potassium iodine. A Tho receiver is synchronised with the j). transmitter and a stylus through which, .g the electrical impulse is passed is placed yi on the sensitised paper and produces the / light and dark shades as the cylinderwe- ;■ volves. The time of transmission does .? not exceed four and a half minutes. Dis- . tance makes no difference to the time occupied, and the power used is no more yy than is required for a distinct telephone conversation. The apparatus was invented by Cap- jc tain Fulton. It is now being made in/A England, but later on it will be manu- ; faetured in Australia. A complete machine for one-way transmission IS/S said to cost not more .than £BOO. Tho receiving portion alone not cost more than £35. The apparatus is now. in practical use by broadcasting stations/;., in England and on the Continent. Daily news bulletins are now being sent out in script from the Rugby stations to ehips at sea.
