  Stromschlussvorrichtung für elektrische   Signaleinrichtungen.   



   Den Gegenstand der Erfindung bildet eine Einrichtung, um unbeabsichtigte Beein-   flussungen   der Stromschlussvorrichtung nach Patent   Nr. 45567 zu verhindern.   



     Alle störenden Beleuchtungsänderungen,   d. h. also diejenigen, die nicht durch die   Zuglaterne   hervorgerufen werden, zu denen also vor allen Dingen die fortwährenden Änderungen der Tageslichtbeleuchtung gehören, nehmen einen verhältnismässig langsamen Verlauf gegenüber den Beleuchtungsänderungen, die durch die am Zuge angebrachte Lichtquelle erzeugt werden. Dieser Umstand   ermöglicht   es, störende   Einflüsse dadurch   unschädlich zu machen, dass man in den Selenzellen-Stromkreis die primäre Wicklung eines Transformators einschaltet, dessen sekundäre Wicklung mit dem Relais verbunden ist.

   Nach dem Gesetz der gegenseitigen Induktion ist die Stärke des sekundären Stromes proportional der   Änderungsgeschwindigkeit   der primären   Stromstärke : man   kann daher bei geeigneten Abmessungen des Transformators und des Relais erreichen, dass   alle Stromänderunges, (lie   von den störenden Einwirkungen herrühren, und die daher einen mehr oder weniger langsamen Verlauf nehmen, so schwache   sekundäre Ströme hervorrufen,   dass das Relais nicht in Tätigkeit gesetzt wird. 



   Auf der Zeichnung ist eine Ausführungsform der Erfindung dargestellt. a ist die am Gleis aufgestellte Selenzelle, b die am Zuge angebrachte Lichtquelle, c die primäre. d die sekundäre Wicklung des Transformators, e das Relais. Dieses wird durch den sekundären Transformatorstrom in Tätigkeit gesetzt, der in dem Augenblick entsteht, wo die von der Zuglampe beleuchtete Selenzelle eine   Vergrösserung   der Stromstärke in der primären Transformatorwiklung c bewirkt. Der Anker f des Relais e schliesst und öffnet wiederum einen aus der Batterie   9   gespeisten Stromkreis, der in bekannter Weise zur Herstellung von Signalen, Signal-Endverschlüssen oder sonstigen Sicherungseinrichtungen benutzt werden kann.

  Current connection device for electrical signaling devices.



   The subject matter of the invention is a device to prevent unintentional influences on the circuit-breaker device according to patent no.



     All disturbing changes in lighting, i. H. that is, those that are not caused by the train lantern, which above all include the constant changes in daylight lighting, take a relatively slow course compared to the lighting changes that are generated by the light source attached to the train. This fact makes it possible to render disturbing influences harmless by switching on the primary winding of a transformer in the selenium cell circuit, the secondary winding of which is connected to the relay.

   According to the law of mutual induction, the strength of the secondary current is proportional to the rate of change of the primary current strength: with suitable dimensions of the transformer and the relay, one can therefore achieve that all current changes (lie from the disturbing influences, and therefore one more or more take less slow course, cause secondary currents so weak that the relay is not activated.



   An embodiment of the invention is shown in the drawing. a is the selenium cell set up on the track, b the light source attached to the train, c the primary one. d the secondary winding of the transformer, e the relay. This is put into action by the secondary transformer current which arises at the moment when the selenium cell illuminated by the train lamp causes an increase in the current in the primary transformer winding c. The armature f of the relay e closes and in turn opens a circuit fed by the battery 9, which circuit can be used in a known manner to produce signals, signal terminations or other safety devices.
