Radio 8 New Marvels For "Home Service"
fy ERE, culled from the radio news of the J U year, is a short account of two recent inventions which may, within 10 years, revolutionise radio programmes the world over. ,
TIHE day is long past TS when the average citizen pauses to reflect on the scientific marvel of xadio. For nearly 15 years we have been familiar with the principle and overation of wireless
telephony and we have now settled down to await, while criticising programmes, the arrival from more populous countries of the physicist’s latest entertainment toy, television. But, by the time television arrives, the radio dealer will have other marvels to offer. If British and American scientists are to be believed, the day is not far distant when the average citizen will receive his morning newspaper in his home by facsimile radio broadcast, the news having been printed during the night on a teletype-like strip of paper. All he need do is attach his. facsimile receiver-a neat little box about the size of a table radio-to the terminals of his radio loud-speaker before going to bed. The copy sent from the newspaper office, whether straight news, photographs or line drawings, involves no printing. The material is inserted in the transmitter, where a tiny bulb, or "scanning light,’’ moves across the page reflecting back to a photoelectric cell the light and dark values of each line. The electric cell in turn converts these light and dark qualities into electrical impulses which can be sent by the radio station through its regular broadcasting equipment.
The receiving set picks up these signals and, by means of | a stylus moving across a roll of carbon-backed paper, reconverts them into the light» and dark lines which form letters and pictures. ,
As if an attachment for a radio set to write a newspaper were not enough, science goes to the other extreme-a newspaper that provides a tadio programme, The talking newspaper is perfeeted--not a radio. but the usual sheet, delivered by hand at your break~fast table. Along the margin will be a strip that. you can tear off and play, Children will hear the. actual voices of characters in their favourite comic strips. Blind and illiterate people will be able to listen to the news of the day they cannot read, told by the men and women who saw it happen. This Mr. W. G. H. Finch, New York radio and telephone expert, has made reality, With forty "sound" inventions to his credit, the "talking newspaper’ is his latest marvel. He has found a method by which sound-tracks. similar to those on a talking film, can be printed on the margin of a newspaper in the same way as the ordinary news. Then the strip, torn off, is played on a tiny home reproducing machine, so simple that a child can operate it, and cheap, since, says Mr. Finch, it can be manufactured for as little as a shilling. The reproducing machine-wmerely a revolving | (Continued on next page.)
