Abstract

362,654. Electric signalling systems. ERICSSON TELEPHONES, Ltd., 67, Kingsway, London, LIMB, F., Holmwood, Fellows Road, and WILMAN, C. W., 7, Grange Avenue, both in Beeston, Notting- ham. Nov. 26, 1930, No. 35578. [Class 40 (i).] Selection for registration purposes at the central station of a totalizator system is effected by shuntwound relays individually responsive to particular combinations of signals over the transmission lines less in number than the relays. As shown in Fig. 1, six horse keys K1 .. K6 are connected with six relays R1 .. R6 by four lines A .. D the connections being such that potential applied to two lines by depression of a key effects the operation of a particular relay only. In another arrangement, Fig. 2, the keys serve to link up the lines in twos and in another modification two batteries of relays for responding to win and place bets respectively are provided and each relay has one winding controlled by a horse key and the other winding by the win and place switch.
