Title: Telegraph exchange system
IPC: H04L12/00
Filed: 1938-05-19
Abstract: 500,848. Telegraph exchange systems. LORENZ AKT.-GES., C. May 19, 1938, No. 14978. Convention date, May 19, 1937. [Class 40 (iii)] A selecting dial is locked until an idle group selector is found, and is released by a short interruption of current transmitted from the exchange. When the subscriber presses his ringing key AT, relays A, B are energized and prepare a circuit for a dial-release relay Wand a busy lamp BL. A relay E at the exchange is also energized and causes a relay R to energize a magnet D which rotates brushes a .. d. When an idle group selector is found, a relay T connects the subscriber's line through and makes the rotary magnet inoperative. A telegraphic relay S receives an impulse of current which is limited by the retarded operation of a busy relay C. The relay S opens the subscriber's circuit for a short period and this causes the relay A to drop, energize the relay W, which frees the dial, and apply the lamp BL to the mains Ne. The auxiliary relay B is retarded to keep the subscriber's loop closed. A relay L, which reverses the polarity of the subscriber's line, is so retarded that it does not respond to the short impulse of current, but only to the continuous current flowing on the establishment of a connection. A polarized relay P then responds to connect up a magnet H, which bridges the relays A, B and dial contacts NSJ and connects up a motor M. The auxiliary relay B now drops and a transmitting contact SK and a receiving magnet EM are connected in the subscriber's line. At the end of a communication, a key ST interrupts the subscriber's loop.
