Abstract
29,165. Kesteren, A. S. J. van. Dec. 19, 1912, [Convention date]. Telephonic relays, repeaters, and translators.- Lines having repeaters for transmission in both directions are arranged to prevent "howling" " due to maintained vibrations. Ordinary or artificial lines L1, L2, Ls, L4 are arranged so that the receiver coils a1, a2 of the respective repeaters are separated from the transmitter coils b2, b1 by sufficient resistance to damp out the reinforcing tendency of the pair of repeaters. The same principle may be applied where a series of repeaters is used, or to a single repeater arranged for bidirectional transmission.
