Claims (1)

Patentanspruch :Claim: Selbsttätige Lichtsignalschaltung nach Patent 536 037, dadurch gekennzeichnet, daß in den Fahrstromkreis eine Drosselspule (E) und in den Haltstromkreis eine Drosselspule (K) gelegt wird, deren Sekundärwicklungen unter Berücksichtigung der Phasenlage den Strom im Haltnot-Stromkreis sperren, falls einer der beiden Stromkreise von Strom durchflossen ist, dagegen unter Einschaltung eines Kondensators (C3) dem Stromverlauf kein Hindernis entgegensetzen, falls beide Stromkreise, Fahrt- und Haltsignalstromkreis stromlos werden.Automatic light signal circuit according to patent 536 037, characterized in that a choke coil (E) is placed in the driving circuit and a choke coil (K) is placed in the holding circuit, the secondary windings of which block the current in the emergency stop circuit, taking into account the phase position, if one of the two circuits is traversed by current, on the other hand, by switching on a capacitor (C 3 ), do not oppose any obstacle to the current flow if both circuits, travel and stop signal circuits are de-energized.
