   Uni den Hiltselektroden b der Entladungsröhren das erforderliche   Gleichstrompotential aufzu-   drucken. sind diese durch weitere Drosselspulen r1 bis r3 mit einem Punkte der Batterie, beispielsweise   dem Nullpunkt-verbunden. Diese Drosselspulen   sind so zu bemessen,   dass   der verstärkte Wechselstrom durch sie keine merkliche Ableitung erfährt.

 an Erde gelegt ist. In der einzigen Verbindungsleitung sind die Kondensatoren   e,   bis ('3 angeordnet. Die   Drosselspulen d1, bis d3 liegen in dem Senderkreis der Verstärker, um den Wechselstrom von der Batterie abzuhalten und dem nächsten Verstärker bzw. dem Telephon zuzuführen.

   Mittels der Drosselspulen     1"1   bis   i'2   ist das Nullpoiential der zugehörigen Batterie an die Hilfselektrode h des betreffenden Verstärkers gelegt. 



   In sämtlichen Ausfübrungsbeispielen können statt der Drosselspulen auch   hoehohmige   Widerstände verwendet werden. die so zu bemessen sind. dass kein erheblicher Teil des verstärkten Wechselstromes der   Weiterleitung   in den nächsten Verstärker oder dgl. entzogen wird. Die Verwendung von Widerständen hat den Vorteil,   dass auch ohne Verwendung von magnetischen Schutzvorrichtungen,   die geringen
Störungsmöglichkeiten die durch die Streufelder von Drosselspulen gegeben sind. vermieden werden. 



   PATENT-ANSPRÜCHE :
1. Reihenschaltung für   Rathodenrohrverstärker,   dadurch gekennzeichnet, dass das Gitter der
Röhre einerseits über eine Kapazität an den durch einen Wechselstromwiderstand geschlossenen Anoden-   @ kreis de- vorangehenden Verstärkers und   anderseits über einen zweiten   Wechselstromwiderstand   an einen bestimmten   Punkt   der Batterie zur Erzielung des erforderlichen Gleichstrompotentiales gelegt ist.

   Print the required direct current potential on the auxiliary electrodes b of the discharge tubes. these are connected to one point of the battery, for example the zero point, through further choke coils r1 to r3. These inductors are to be dimensioned in such a way that the amplified alternating current does not experience any noticeable dissipation through them.

 is placed on earth. The capacitors e, to ('3 are arranged in the single connecting line. The choke coils d1 to d3 are located in the transmitter circuit of the amplifier in order to keep the alternating current from the battery and to feed it to the next amplifier or the telephone.

   The zero potential of the associated battery is applied to the auxiliary electrode h of the amplifier in question by means of the choke coils 1 "1 to i'2.



   In all of the exemplary embodiments, high-value resistances can also be used instead of the choke coils. which are to be measured in this way. that no significant part of the amplified alternating current is withdrawn from the transmission to the next amplifier or the like. The use of resistors has the advantage that, even without the use of magnetic protection devices, the low
Disturbance possibilities that are given by the stray fields of choke coils. be avoided.



   PATENT CLAIMS:
1. Series connection for Rathoden tube amplifier, characterized in that the grid of the
Tube is placed on the one hand via a capacity on the anode circuit of the preceding amplifier closed by an alternating current resistance and on the other hand via a second alternating current resistance to a certain point of the battery to achieve the required direct current potential.
