Abstract

357,024. Multiplex systems. HORST, W. P. C. VAN DER, 80, Valkenboschlaan, The Hague. Dec. 2, 1930, No. 36329. Convention date, Dec. 4, 1929. [Class 40 (iv).] The spaces (between words or even between syllables) in one message are utilized for the transmission of another by recording both, mechanically, magnetically, or photographically, reproducing and transmitting one, e.g. by wireless, and causing the occurrence and cessation of pauses in this message to start and stop the reproduction of the second message. The arrangement may be extended to cover three or more messages. Means may be provided also whereby after a given number of spaces in the first message its place is taken by the second and that of the second by the third, and so on. Arrangements may be provided for making short spaces ineffective.
