Abstract

516,138. Railway points & signal operation. VEREINIGTE EISENBAHN-SIGNALWERKE GES. June 21, 1938, No. 18451. Convention date, July 1, 1937. [Classes 104 (i) and 105] [Also in Group XXXVIII] Railway points or 'signals are selectively operated by applying currents of different frequencies f<1>, f<2>, f<3> on a line circuit G, L, with filter circuits such as s<1>, and s<11> for the frequency f<1> whereby control relays are operated to apply power current from the mains Z. D to the motors of the machines A<1>, A<2>, A<3>. Return indication currents are applied to a line circuit O, P and operate indication relays R', R<2>, R' through filter circuits s<12>, s<22>, s<32>. The power current and return indication currents may flow in the same line circuit as the control currents. For the opposite operation of the points the control current may be modulated by interruption or in strength.
