  Verfahren zur   Hervorblingung von Blinidicht   für   Eisenbahnsignalanlagen.   



   Bei Signalanlagen für Eisenbahnzwecke wird zur leichteren Sichtbarmachung der Signale bereits Blinklicht verwendet. Die Erfindung bezieht sich auf ein besonderes Verfahren, bei elektrischen, mit Wechselstrom gespeisten Signallampen dieses Blinklicht hervorzubringen. Gemäss der Erfindung erfolgt die Speisung der Lampen durch zwei Wechselstromerzeuger, die in ihrer Frequenz gegeneinander ungleich sind. Werden derartige Stromerzeuger auf denselben Verbraucher geschaltet, so ergibt sich bekanntlich die Erscheinung, dass in dem durch den Verbraucher fliessenden Wechselstrom langsame Schwingungen 
 EMI1.1 
 scheinung ist ja genügend durch die Verwendung der Phasenlampe beim Parallelschalten von Wechselstrommaschinen in Zentralen bekannt. 



   Die Erfindung hat gegenüber den bisher üblichen Verfahren zur Erzeugung des Blinllichtes durch völliges Ein-und Ausschalten des Lampenstromes den Vorteil, dass Kontakte fehlen und dass die Zeitdauer des Blinkens sehr leicht auf beliebige Beträge einreguliert werden kann. 



   Es können natürlich auch mehr als zwei Stromerzeuger in der beschriebenen Weise parallel geschaltet werden.

  Method for highlighting Blinidicht for railway signal systems.



   In signal systems for railway purposes, flashing lights are already used to make the signals easier to see. The invention relates to a special method for producing this flashing light in electrical signal lamps fed with alternating current. According to the invention, the lamps are fed by two alternating current generators, which are mutually different in frequency. If such power generators are switched to the same consumer, it is known that the phenomenon occurs that slow oscillations in the alternating current flowing through the consumer
 EMI1.1
 appearance is well known from the use of the phase lamp when connecting alternating current machines in parallel in control centers.



   The invention has the advantage over the previously customary methods for generating the flashing light by completely switching the lamp current on and off that there are no contacts and that the duration of the flashing can very easily be adjusted to any desired amount.



   Of course, more than two power generators can also be connected in parallel in the manner described.
