ROBOT ACTS.

ROOM LIGHTED BY PISTOL SHOT. EXTREME SENSITIVENESS. A glimpse into the future, when electricity, transmitted without wires, will provide not only entertainment hut light and power, was furnished by Mr. S. M. Kintner. research manager of the Westinghouse Eleotnic Company, iu a demonstration at Pittsburgh. United States, says the “Daily Mail.” Mr. Kintner presented several novel el ectriua l de.v ices. i ncfmti ng : A new robot, Trelelux—.“'brother of Tele vox”—‘which, from a distance, was made to turn off and on the lights in the room. •

A. musical beam of light, by which music produced on a phonograph was carried without wires, to a loudspeaker across the room.

Knowles grid-glow tuibe and photoglow tube, which may be used: indefinitely without using - any appreciable amount of current.

A model showing how airports may be illuimiinated at night at the sound of an airplane motor. The Telelux ,the latest mechanical -servant to come from the Westinghouse labor atonies, is directed through the .medium of light beams rather than bv -sound, as is tin* ease with the Televox .

Tib© Telelux utilises two photo-elec-Miie cells, which. are sensitive to: a beam of light thrown Upon it by a light pistol hold by the operator. dine of the cells is the selector, whi ch prog rest vetly chooses any one of three circuits. Then the beam of light is tl ashed on the operator cell, and Teilolux opens or closes the chosen circuit.

At tlie demonstration the Telelux turned off and on the lights in the room unerringly. From one to three flashes of light on the selector cell would determine which group l of lights were to be. turned out, then a- single flash on the operator cell, .and Telelux would turn oft the. lights. It Is possible to operate the Telelux from a; distance of 75ft.

Mr. [vintner also explained, the poisibilifics of power Lransim,ssion. by holt radio waves.

f 1.0 brought a. picture of the day when electric light users would tune in on a' power station for their light current <is‘ they now tune in on a radio broadcasting station.
