Abstract: 393,738. Automatic exchange systems. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, and DIXON, R. G., .162, Westmount Road, Eltham Park, both in London. April 26, 1932, No. 11982. [Class 40 (iv).] A link circuit which may be held indefinitely in association with a line on which permanentloop conditions exist becomes freed from that association when required for a new call. The permanent-loop conditions may arise from the non-arrival of impulses or the failure of a subscriber to hang up after calling a busy line. The invention is described with reference to a small system of ten lines with four finderconnector links allotted for use in turn by a relay chain SAC. Normal operation. Two-step line-and-cut-off relay L operates in series with common start relay ST and closes contact l1. Relay ST operates relay S in the first idle link FC connecting up stepping relay DR which interacts with finder magnet FM. When the calling line is reached, relay K operates in 'series with the right-hand winding of relay L, and relays A, B, C energize. Impulses are repeated by relay A to connector magnet CM and at the end-of the digit between the relapse of relays C, E, the test relay H is connected to wiper cs4 over contacts of an off-normal relay ON. Called line busy. If H does not operate, relay PG operates over its lower winding when E falls back, short-circuiting K which releases A, B and causes the connector to return to normal over a circuit including contacts of relay ON. Relay PG remains locked over the loop and the conditions are the same as for a permanent loop. Permanent loop. If no impulses are received, thermostatic relay TC operates energizing PG which short-circuits K and locks over the loop, releasing relays A, B. If the link is required for a new call the operation of relay S energizes DR which releases PG and steps the finder on to the next terminals. Relay allotting- arrangements. The links are' allotted in strict rotation and if an allotted link is busy the incoming starting lead is extended over contacts of relay B or ON to the next link. With the allotter relays all unoperated as shown, the first link is allotted and when ST operates relay P energizes over winding (i) and prepares a locking circuit over Q(i). When ST releases Q operates to switch over to the second link. When ST operates for the next call, differential winding (ii) of relay P is energized so that P releases but Q remains held until ST releases. Relays P, Q then go through a similar cycle for calls over the third and fourth links, which are connected up by a second pair of double-wound relays PP, QQ controlled by relay Q in exactly the same way as P, Q are controlled by ST.
