Description

Empfänger mil_ Schwundausgleich Im Hauptpatent ist ein Empfänger mit Schwundausgleich beschrieben, bei dem sich die Kathoden der zu regelnden Röhren auf einem gegenüber den übrigen Kathoden positiven Potential befinden und bei dem die Regelspannung von einem zwischen der Anode der Gleichrichterröhre und dem negativen Pol der Anlodenspannungsquellie liegenden zusätzlichen Potentnometer abgenommen wird.Recipient mil_ Schwundausgleich A recipient is included in the main patent Described loss compensation, in which the cathodes of the tubes to be regulated are at a positive potential compared to the other cathodes and at which the control voltage of one between the anode of the rectifier tube and the negative Pole of the anode voltage source removed from the lying additional potentnometer will.

In der Abbildung ist eine solche Anordnung dargestellt. i bedeutet hierbei die Glelchrichterröhre, q. die Hochfrequenzröhre, deren Verstärkung geregelt wird. Wie in dem Hauptpatent genauer beschrieben, wird zu diesem Zweck die Kathode durch den Spannungsteiler 5-6 auf ein positives Potential gebracht, während ein von dem Spannungst ei iler2,3 abgegriffener Teil der Regelspannung dem Gitter der Hochfrequenzröhre zugeführt wird.Such an arrangement is shown in the figure. i means here the rectifier tube, q. the high-frequency tube, whose gain is regulated will. As described in more detail in the main patent, the cathode is used for this purpose brought to a positive potential by the voltage divider 5-6, while a part of the control voltage tapped by the voltage divider2,3 the grid of the High frequency tube is fed.

Da die Daten einer Röhrengattung unter sich schwanken, müßte beim Auswechseln einer Gleichrichterröhre der Spannungsteiler 5-6 so geändert werden, daß beim Fehlen einer Amplitude die Anodenspannung der Gleichrichterröhre i ungefähr gleich der Kathodenspannung der Hochfrequenzröhre q. ist. Da diese Maßnahme umständlich ist, wird nach der vorliegenden Erfindung ein Spannungsteiler g vorgesehen, mit dem sich die Schinngitterspannung der Gleichrichterröhre i einstellen läßt. Durch Variieren der Schirmgittexspannung ändert sich der Anodenstrom dieser Röhre und infolgedessen auch die Anodenspannung, so daß es beim Auswechseln einer Röhre leicht .möglich ist, wieder die ursprünglichen Bedingungen zu schaffen.Since the data of a tube type fluctuate among themselves, the Replacing a rectifier tube the voltage divider 5-6 can be changed so that in the absence of an amplitude the anode voltage of the rectifier tube i approximately equal to the cathode voltage of the high frequency tube q. is. Because this measure is cumbersome is, according to the present invention, a voltage divider g is provided with which can be used to adjust the lattice voltage of the rectifier tube i. By Varying the screen grid voltage changes the anode current of this tube and consequently also the anode voltage, so that it is easy to change a tube . it is possible to restore the original conditions.

Mit dem Potentirometer 7 läßt sich die der Röhre 8 zugeführte Niederfrequenzamplitude einstellen. Mit i i ist ein Siebkondensator für die Regelspannung und mit io der Netztransformator bezeichnet.With the potentirometer 7, the low-frequency amplitude fed to the tube 8 can be measured to adjust. With i i is a filter capacitor for the control voltage and with io the Network transformer called.
