Abstract
1,072,826. Signal control. SOCIETE TECHNIQUE POUR L'INDUSTRIE NOUVELLE S.A. " STIN." Feb. 16, 1966 [March 1, 1965], No. 6711/66. Heading B7N. Arrangement for controlling e.g. a signal 30 when the route to which it gives entry has been set up, comprises a circuit simulating the track layout, manually or automatically operated signal switches 531-536 and command receiving circuits 500, 510 associated with signals 30 and 31 respectively. Assume a route from signal 30 to exit GB, the normal positions of points 32, 33 and 35 required for this route is proved by relay contacts 521, 522 and 524 in the positions shown so that operation of signal switch 533 applies a positive voltage via its contact to receiver 500. The receiver includes a relay with a pair of series-connected, opposed windings 501, 502 connected across the D.C. source with a centre tap connected to the switching circuit and a pair of slave relays 505, 506 connected to the switching circuit and to the positive and negative terminals of the source, respectively. The positive voltage applied by the switching circuit unbalances the double-wound relay which picks up closing contacts 503, 504. As a result relay 506 is energized, opening contact 554 to switch off red signal lamps 555 and closing contact 552 to energize yellow lamp 557.
