  Empfänger für drahtlose Signalübertragung. 



   Gegenstand vorliegender Erfindung bildet eine weitere Ausgestaltung an   Empfängern 1   der in dem   österreichischen   Patente Nr.'26405 gekennzeichneten Art und besteht im Wesen darin, dass   paraile ! zum Wellenindikator   ein Hilfskondensator eingeschaltet wird. 



   Der Zweck der neuen Kondensatorschaltung ist folgender : Bei einem hohe Selbst-    induktion aufweisenden'Wellenindikator des in.   dem Stamm-Patente beschriebenen Empfängersystems beanspruchen die im System auftretenden Stromstösse zum Passieren des Detektors ein bestimmtes Zeitintervall ; bei rasch aufeinanderfolgenden Unterbrechungen der Kontaktvorrichtung ist daher Gefahr vorhanden, dass nicht die ganze, sondern nur ein Teil der zur Verfugung stehenden Energiemenge den Detektor wirklich   beeinflusst.   Durch die neue Kondensatorschaltung wird dieser Übelstand beseitigt, da in dem Hilfskondensator die   Einzelladungen derart gesammelt   werden, dass letztere auch nach Unterbrechung der Kontaktvorrichtung durch den Detektor sich entladen können. 



   In der Zeichnung ist ein Schaltungsbeispiel für das neue Empfangssystem dargestellt. a und   h   veranschaulichen   Primär- bzw. Sekundärspule eines   Transformators, welcher die vom Räume aufgenommene Energie transformieren, c den bei derartigen Empfängern üblichen Kondensator und d den in dem Stamm-Patente angegebenen intermittierenden Unterbrecher. a bezeichnet den Wellenindikator, in diesem Falle ein Telephon und f jenen Kondensator, dessen Anordnung Gegenstand vorliegender Erfindung bildet.

  Receiver for wireless signal transmission.



   The subject of the present invention is a further embodiment of receivers 1 of the type identified in the Austrian patent no. '26405 and essentially consists in the fact that paraile! an auxiliary capacitor is switched on for the wave indicator.



   The purpose of the new capacitor circuit is as follows: With a high self-induction wave indicator of the receiver system described in the parent patents, the current surges occurring in the system require a certain time interval to pass the detector; in the event of interruptions in the contact device in rapid succession, there is therefore a risk that not all but only part of the amount of energy available will actually affect the detector. This inconvenience is eliminated by the new capacitor circuit, since the individual charges are collected in the auxiliary capacitor in such a way that the latter can discharge even after the detector has interrupted the contact device.



   The drawing shows a circuit example for the new receiving system. a and h illustrate the primary and secondary coils of a transformer, respectively, which transform the energy absorbed by the room, c the capacitor common in such receivers, and d the intermittent breaker indicated in the parent patents. a denotes the wave indicator, in this case a telephone, and f denotes the capacitor, the arrangement of which forms the subject of the present invention.
