Abstract

148,990. Bethenod, J. April 28, 1919, [Convention date]. Track apparatus actuating signals on trains.- Signalling-apparatus R on a train is operated by the reaction of coils S wound on frames without iron cores and laid on the track so as to be parallel to similar coils P on the train to which high-frequency current is supplied, suitable capacities C1, C2, being inserted in the circuit of the coils. Signals may be distinguished by alterations in the impedance in the circuit of the coil on the track without breaking the circuit or by breaking the circuit by connexions D to the signals.
