Here and There

WO-WAY television, in conjunction ‘ with ordinary telephones, was demonstrated recently in New York, The conversation was made possible by the use of the "iconophone," and was carried on as though the person at the other end of the wire were in the same. room. The speakers were able to see and hear each other as. if they were conducting a conversation with someone at an open window 10 or 12 feet away, though the actual separation was about three miles. Dr. Frank Jewett, president of the Bell Telephone: ‘Laboratories, explained that the system employed was not yet feasible, ‘\ * *. * GLIDER was recently towed: across the American Continent by an aeroplane, arriving safely at New: York in less than forty hours’ flying time. Included in the glider’s equipment was a radio transmitter and receiver for maintaining communication with radio air beacons. * * * 4 NOTHER interesting stage. in: wireless picture transmission was reached recently, when a short-wave Californian station successfully transmitted the entire front page of a newspaper to a receiver in Schenectady, New York. * ie NEW York motor: dealer has hit upon the happy scheme of giving away a wireless set with every secondhand car sold. It is stated that since he instituted the custom,. he’ has never received apy complaints-about the sets. * oe * S an experiment, a Detroit dairy company recently installed modern radio equipment in the cow barns, and found that the milk herd appreciated the music. Since the advent of. the radio, dairymen keeping close tabulation found that milk production has-in-creased considerably, the company attributing the increase to. the music alone. _* s JRPADIO-EQUIPPED balloons that automatically report atmospheric conditions .encountered in free fligh have recently been tested out in sia and France. The French device sends out radio signals at regular intervals showing barometri# pressuré and temperature encountered by the balloon. ‘These are received both as audible signals and by a recording pen. In this instrument a make-and-break device is used to indicate ‘barometer and thermometer readings by the duration of the signals. A radio pilot balloon, developed by the United States Signal Corps, has proved a success when used for indicating the speed and direction of the upper winds. A small radio transmitter is sent aloft attached to three hydrogen-filled balloons. At various ground stations the direction from which signals come-is determined by apparatus such as is used with the radio compass, and reported to a. central point where the movements are worked out and plotted.
