Abstract
985,862. Route setting. SOC. TECHNIQUE POUR L'INDUSTRIE NOUVELLE S.A. May 9, 1961 [May 11, 1960], No. 16777/61. Heading B7N. In a route setting system in which the route setting circuit networks simulate the track layout and include switching elements which indicate the track condition, at least two such identical networks may be combined into a common network and supplied with currents of different character or frequency, each current being associated with one of the original networks. The two circuits in Fig. 2, may be combined as shown in Fig. 3, feeding devices F1- F4, F1<SP>1</SP> to F1<SP>111</SP> and F2<SP>1</SP> to F2<SP>111</SP> being provided to generate the currents at different frequencies and being provided with filters to accept particular frequency currents. Specifications 793,945 and 829,445 are referred to.
