Description
Relais für unduliärende Ströme. Bei der bisherigen Schaltungsweise der Röhre nach dem Hauptpatent 351285 waren fünf Elektroden erforderlich. Der Transforinatortl- war an zwei Zwischenelektroden3 und 4 angeschlossen. Der Bau der Röhre läßt sich vereinfachen, wenn die eine Zwischenelektrode4 fortgelassen wird, ohne daß etwa der freie Pol des Transformatorst' an (lie Anode5 gelegt wird. Der freie Pol des Transforrnatorst' wird vielmehr an einen nach Umständen, einzustellenden Kapazitätsnebenschluß zur Elektrode 3 gelegt, und zwar außerhalb der Röhre a, wie es in der Abbildung bei p dargestellt ist. Hierbei ist bei der Schaltung darauf zu achten, daß nicht ein Schwingungsmoment entsteht, das störend auf die Wiedergabe des Ferngesprächs einwirkt. Anderseits kann durch die neue Anordnung Zn# erreicht werden, daß ein bestimmter Ton durch Resonanz bevorzugt wird. Durch diese Schaltung wird bewirkt, daß die Kapazität zwischen den früheren Anschlußelektroden 3 Lind 4 des Transformators t' aus dem Inneren der Röhre in regelbare und zugängliche Form herausverlegt ist. . Relay for permanent currents. In the previous circuit of the tube according to the main patent 351285, five electrodes were required. The transformer was connected to two intermediate electrodes 3 and 4. The construction of the tube can be simplified if one Zwischenelektrode4 is omitted without about the free pole of the transformer T 'to (lie Anode5 is placed. The free pole of Transforrnatorst' is instead applied to one circumstances adjusted capacitance shunt to the electrode 3 , namely outside the tube a, as shown in the figure at p . Care must be taken when switching the circuit that no oscillation moment arises that has a disruptive effect on the reproduction of the long-distance call. On the other hand, the new arrangement Zn # This circuit has the effect that the capacitance between the previous connection electrodes 3 and 4 of the transformer t 'is moved out of the interior of the tube in a controllable and accessible form .
