Abstract

529,026. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., TAYLOR, R., and BAKER, G. T. March 23, 1940, No. 11280. Divided out of 528,971. Drawings to Specification. [Class 40 (iv)] A mechanical regenerator which is generally similar to that described in Specification 458,095 is adapted for the storing and repeating of signals in a five unit code consisting of two operative impulses in characteristic positions with respect to five timing impulses by arranging for the receiving magnet to be stepped by the timing impulses and for the marking magnet to be released to displace pins in positions in accordance with the operative signals. The signals are repeated by means of two sets of interrupter springs which are closed alternately by the sending disc. One set controls the outgoing impulses and the other controls a test for the displaced pins whereby the character of the impulses corresponding to displaced pins is changed. As shown the timing impulses are of 50 cycles and the operative impulses of 50 + 150 cycles. The invention is described with reference to a system identical with part of that described in Specification 528,971.
