Description

Im Patent g25 355 ist ein Elektronenröhren-Verstärker beschrieben, bei welchem die Verstärkerröhre mit einer Selbsterregerschaltung versehen ist, mit Hilfe deren in der Röhre dauernd eine Eigenschwingung höherer Frequenz als die der zu verstärkenden Eingangsspannung erzeugt wird, und bei dem die Gittervorspannung, die Anodenspannung, die Rückkopplung und die Dämpfung derart eingestellt sind, daß eine Änderung der zu verstärkenden Spannung den mittleren Anodenstrom stärker ändert, als es ohne die selbsterregte Eigenschwingung der Fall ist.In patent g25 355 an electron tube amplifier is described, in which the amplifier tube is provided with a self-exciting circuit, with With the help of which in the tube there is a constant natural oscillation of higher frequency than that of the to be amplified input voltage is generated, and at which the grid bias, the anode voltage, the feedback and the attenuation are set such that a change in the voltage to be amplified changes the mean anode current more strongly, than is the case without the self-excited natural oscillation.

Die Erfindung betrifft die Anwendung einer gemäß dem Hauptpatent geschalteten und betriebenen Verstärkerröhre als Zweirichtungsverstärker in Zweidrahtleitungen in der Weise, daß die Verstärkerröhre als Zweipol an eine dritte Wicklung eines in den Leitungszug eingeschalteten Übertragers angeschlossen ist.The invention relates to the use of a circuit according to the main patent and operated amplifier tubes as bidirectional amplifiers in two-wire lines in such a way that the amplifier tube as a two-pole connection to a third winding of a is connected to the transformer switched on in the cable run.

Eine Ausführungsform der Erfindung ist in der Zeichnung dargestellt. In dieser bedeutet io eine von einer Stelle A nach einer Stelle B führende Zweidrahtleitung, in welcher ein Übertrager mit den beiden Wicklungen 1i, 12 eingeschaltet ist. Der Übertrager besitzt eine dritte Wicklung 13, an welche die im Hauptpatent beschriebene und in der Zeichnung nur schematisch dargestellte Verstärkerröhre als Zweipol angeschlossen ist. Durch die von A nach B oder in umgekehrter Richtung gesandten Signalströme, die den Übertrager 1i, 12 eireichen, wird in der dritten Übertragerwicklüng 13 eine Spannung induziert, die dem Anodenkreis der Verstärkerröhre 13 zugeführt wird statt dem Gitterkreis, wie es im Hauptpatent beschrieben war. Wie Versuche gezeigt haben, tritt nun auch bei dieser Schaltung eine Verstärkung auf, die größer ist, als sie ohne die selbsterregte Eigenschwingung der in der Zeichnung gezeigten Röhre in Zweipolschaltung erzielt wird, und zwar unabhängig davon, ob die Signale von A nach B oder in umgekehrter Richtung übertragen werden.An embodiment of the invention is shown in the drawing. In this, io means a two-wire line leading from a point A to a point B , in which a transformer with the two windings 1i, 12 is switched on. The transformer has a third winding 13 to which the amplifier tube described in the main patent and only shown schematically in the drawing is connected as a two-pole. The signal currents sent from A to B or in the opposite direction, which eireichen the transformer 1i, 12, induce a voltage in the third transformer winding 13 , which is fed to the anode circuit of the amplifier tube 13 instead of the grid circuit as described in the main patent. As tests have shown, a gain now also occurs with this circuit that is greater than that achieved without the self-excited natural oscillation of the tube shown in the drawing in a two-pole circuit, regardless of whether the signals are from A to B or in can be transmitted in the opposite direction.
