 und t gelegt, welche einen bequemen Weg für die das Gitter hl beeinflussende Hochfrequenz. die vom Transformator q oder einem der Transformatoren u1, u2, u3 induziert wird, schaffen. Als Sender kann jede beliebige Einrichtung dienen, die erlaubt, in zeitlich bestimmter Aufeinanderfolge die Anzahl von   Hochfrequenzstössen über   eine Leitung L zu geben. 



   Nachdem die Folge der Kondensatoren c1, c2, c3, c4 durch einen über die Leitung L ankommenden   Hoehfrequenzstoss   entladen ist. bedarf es einer gewissen Zeit, bis nach Verschwinden der Leitfähigkeit in den Ventilzellen die Kondensatoren durch die Batterie g über die Widerstände r1, r2, r3, r4 wiederum aufgefallen sind und die ganze Schaltung in Bereitschaft für ein neues Signal gekommen ist. 



   Statt der Beeinflussung über die Leitung L kann diese auch auf   drahtlosem   Wege geschehen. 



     PATENT-ANSPRACHE   :
1. Einrichtung zur selektiven Auswahl von Empfängern über eine gemeinsame   Verbindung-   
 EMI2.2 
 deren Gesamtdauer kleiner als die Periode der Synchronisierimpulse des Senders ist.

 and t placed, which is a convenient way for the high frequency influencing the grating hl. which is induced by the transformer q or one of the transformers u1, u2, u3. Any device that allows the number of high-frequency surges to be transmitted over a line L in a specific time sequence can serve as a transmitter.



   After the sequence of capacitors c1, c2, c3, c4 has been discharged by a high-frequency surge arriving via line L. it takes a certain time before the capacitors through the battery g via the resistors r1, r2, r3, r4 are again noticed after the conductivity in the valve cells has disappeared and the whole circuit is ready for a new signal.



   Instead of influencing via the line L, this can also be done wirelessly.



     PATENT APPROACH:
1. Device for the selective selection of recipients via a common connection

 whose total duration is less than the period of the synchronization pulses from the transmitter.
