TUNE IN, BUT LISTEN LATER BY NEW IDEA Radio Concerts Is Innovation of European Experts. Hi! NHA .Ven ice LONDON, Sept. 21. —Deferred radio concerts, with possible extension of this idea to radio vision, is the latest Innovation introduced by European scientists. Two Viennese inventions, Dr. Mo-reno-Levy and Franz Lornitzo, report having perfected a device that receives radio programs but doesn’t make them audible until the listener decides to hear it. In other words, the instrument records a radio concert and keeps it even permanently If the fan desires. The significance of this invention lies in its capacity to record for posterity addresses of famous men, and other noteworthy talks and songs broadcast by radio. Another advantage lies in the fact that a similar Instrument can be used for broadcasting, so that an artist may record his voice on the instrument, which in turn would broadcast the song. In this way, only perfect renditions could be broadcast, for mistakes could easily be rectified before broadcastaing. A steel band, somewhat like a movie film, is drawn through the electro-magnet of a radio headphone, so as to be magnetized in accordance with the electric impulses sent through the instrument from the receiver. This Action takes place befcHkthe headphone magnet has a ■■He to vibrate the thin diaphram Hi at turns the electrical vibrations Pnto sound. This magnetized steel hand can, any time later, be run through a similar electro magnet, producing the electric vibration" that result in the soilnds heard in i. .ei of headphones. After use, the steel band can be demagnetized and used- again for the reception of another program. If the receiving fan wants to keep it permanently he may do so, just as he might keep a phonograph record. This.idea is said to have been invented. as early as 1898, in the application to telephone, recording the calls while a person js out, and being us Ad to report them When the recipient returns. According to further information, the inventors of this device see in it a possibility for its use in radio television.
