Secret Documents Sent by Radio (Jan, 1932)
Secret Documents Sent by Radio
M. BELIN, a French inventor, has perfected a machine known as the “Belinogram”, which makes it possible to send by wireless with absolute safety documents of the most secret nature. The sending machine Belin has developed decomposes the message, document or photograph, while the receiver employed assembles the electrical impulses into the original form. Any other machine, although receiving the same document, finds the signals altogether distorted and of no value whatever.
