 beider aufnimmt. Erst dieser ist dann mit der Antenne gekoppelt. 



   Fig. 3 zeigt die Anwendung der Schaltungseinrichtung für drahtlose Telephonie. Parallel   zum   Kondensator   K1   des   Audionkreises     82 liegt   der Sender T, der entweder ein   Widerstandsmikrophon   oder ein Kapazitätstelephon sein kann, dessen Kapazität sich gemäss den Sprechschwingungen ändert. Durch diese   Kapazitätsschwankungen   wird die Frequenz der des Audionkreises entsprechend variiert. Diese Frequenzschwankungen erscheinen daher ebenso in dem (aperiodisch ausgebildeten)   Steuerkreis 82   und zuletzt im   Lichtbogenkreis   L, dem die Frequenz des Audionkreises aufgezwungen wird.

   Da der Lichtbogenkreis durch die Koppelung   J12   mit dem scharf abgestimmten Kreis S3 und dieser durch M3 mit der Antenne gekoppelt ist, werden die Frequenzschwankungen Verstimmungen erzeugen, die wieder Intensitätsschwankungen hervorrufen. In die Antenne gelangen also Schwingungen, deren   Intensität   gemäss den   Sprechsehwingungen schwankt.   



   PATENT-ANSPRÜCHE   :  
1. Einrichtung zur Erzeugung elektrischer Schwingungen mittels Lichtbogen, dadurch gekennzeichnet, dass ein Lichtbogenschwingungskreis durch einen selbständig schwingenden Elektronenröhrengeneratorkreis gesteuert wird. so dass er zwangsweise dessen Frequenz erhält.

 both take up. Only this is then coupled to the antenna.



   Fig. 3 shows the application of the wireless telephony circuitry. The transmitter T, which can either be a resistance microphone or a capacitance telephone, the capacitance of which changes according to the speech oscillations, is located parallel to the capacitor K1 of the audio circuit 82. Due to these fluctuations in capacity, the frequency of the audio circuit is varied accordingly. These frequency fluctuations therefore also appear in the (aperiodic) control circuit 82 and finally in the arc circuit L, on which the frequency of the audio circuit is imposed.

   Since the arc circuit is coupled to the sharply tuned circuit S3 through coupling J12 and the latter is coupled to the antenna through M3, the frequency fluctuations will generate detunings which again cause intensity fluctuations. Vibrations get into the antenna, the intensity of which fluctuates according to the speech vibrations.
