Electronic safety circuits

Abstract: Electronic safety circuit intended to produce an output signal in the event of wearing out or failure of one of its components, the circuit comprising a magnetic circuit having a rectangular hysteresis cycle, a control circuit connected to the magnetic circuit and to the other components which are under surveillance, this control circuit acting in a balanced fashion on the magnetic circuit when all the components of the circuit under surveillance function normally, but producing an unbalanced action when at least one of these components is defective, and an output circuit producing an output signal in the event of an unbalanced action on the magnetic circuit.

Continuous transport system for trains with programmed vehicles

Abstract: A continuous transport system for trains with programmed vehicles. The system comprises at each station a connection track (H10, H20, H11, H21, H13, H23) linking the outward track (OX) to the return track (X''O'') or conversely, to enable a train travelling from a high density traffic area to a less dense traffic area, to reduce the number of its vehicles and, to enable a train travelling in the opposite direction to recover vehicles. The system for transporting persons comprises a minimum number of vehicles to ensure maximum flow.
