Description

Fremdgesteuerter Sender Zusatz zum Patent 482 448 Das Patent d.82 448 betrifft einen fremdgesteuerten Sender, bei welchem die gesteuerte Röhre oder die Steuerröhre gleichzeitig als Modulationsröhre für die Steuerröhre bzw. gesteuerte Röhre wirkt. Dabei erfolgt die niederfrequente Kopplung der Röhren .durch niederfrequente Kopplung der Anodenkreise.Externally controlled transmitter Addition to patent 482 448 The patent d.82 448 relates to an externally controlled transmitter in which the controlled tube or the control tube at the same time as a modulation tube for the control tube or controlled Tube works. The low-frequency coupling of the tubes takes place through the low-frequency Coupling of the anode circuits.

Gemäß der Erfindung erfolgt nun die niederfrequente Kopplung der Röhren durch niederfrequente Kopplung des Anodenkreises der einen Röhre mit dem Gitterkreis der anderen.According to the invention, the low-frequency coupling of the tubes now takes place by low-frequency coupling of the anode circuit of one tube with the grid circle the other.

Die Zeichnung zeigt eine Ausführungsschaltung gemäß der Erfindung.The drawing shows an embodiment circuit according to the invention.

Im Gitterkreis der Steuerröhre G liegt die Kopplungsspule für den Schwingungskreis S und ein Kondensator C.., zu welchem parallel die eine Wicklung eines Transformators T geschaltet ist. Die andere Wicklung dieses Transformators liegt im Anodenkreis der gesteuerten Röhre V hinter deren Schwingungskreis N. Ferner ist hinter diese andere Spule ein Kondensator C geschaltet, zu dem parallel die Anodenbatterie A liegt.In the grid circle of the control tube G is the coupling coil for the Oscillating circuit S and a capacitor C .., to which one winding is parallel a transformer T is connected. The other winding of this transformer lies in the anode circuit of the controlled tube V behind its oscillation circuit N. Furthermore a capacitor C is connected behind this other coil, to which the Anode battery A is on.

D,ie Steuerröhre G ist kapazitiv über den Kondensator C, mit der gesteuerten Röhre Il gekoppelt, in deren Gitterkreis eine Selbstinduktion L, zur Abschirmung der Hochfrequenz und ein Kondensator C2 liegt, zu dem parallel der Modulationstransformator Tm ge- schaltet ist, der durch das Mikrophon beeinflußt wird. Die Schaltung entspricht somit im wesentlichen der Schaltung nach Abb. r des Patentes q.82 448, abgesehen davon, daß statt der dort verwandten Drosselspule DY ein Transformator T verwandt wird, -der den Gitterkreis der Röhre G beeinflußt, so daß hier die niederfrequente Kopplung der Röhren G, Z' durch niederfrequente Kopplung des Anodenkreises der Röhre V mit dem Gitterkreis der Röhre G erfolgt.D, ie control tube G is capacitively coupled via the capacitor C, with the controlled tubular Il, in the grid circuit of a self-inductance L, is to shield the high-frequency and a capacitor C2, to the parallel of the modulation transformer Tm overall on, by the Microphone is affected. The circuit thus corresponds essentially to the circuit according to Fig. R of patent q.82 448, apart from the fact that instead of the inductor DY used there, a transformer T is used, which influences the grid circuit of the tube G, so that the low-frequency coupling here of the tubes G, Z 'by low-frequency coupling of the anode circuit of the tube V with the grid circle of the tube G.

Natürlich kann die Anordnung auch so getroffen werden, daß der Gitterkreis der gesteuerten Röhre mit dem Anodenkreis der Steuerröhre niederfrequent gekoppelt ist.Of course, the arrangement can also be made so that the grid circle of the controlled tube is coupled to the anode circuit of the control tube at a low frequency is.
