Abstract

460,903. Electric signalling systems. STANDARD TELEPHONES & CABLES, Ltd., and McWHIRTER, E. M. S. Aug. 6, 1935, No. 22171. [Class 40 (i)] In a system for indicating the positions of a plurality of apparatus, such as circuit breakers, each apparatus controls a change-over contact 1, 2, 3, &c. which is connected to the mid-point of series connected condensers C1, C<1>1, &c. and to an individual contact of the distributer S which is adapted to run in synchronism with a similar distributer at the receiver. The contact is adapted to mark the transmitting distributer with positive or negative battery according to the position of the associated apparatus and when changed over to cause charging and discharging of the condensers through relays A, B which operate the " start " relay ST of the distributers.
