Einrichtung zum verstärkten Empfang gedämpfter und ungedämpfter Schwingungen.Device for increased reception of damped and undamped vibrations.
Die Erfindung betrifft eine Einrichtung zum verstärkten Empfang gedämpfter und ungedämpfter Schwingungen, bei welcher in einer Empfangsschaltung mit Vakuumröhre im Anodenkreis ein nur Niederfrequenz führender Nebenzweig vorgesehen ist. Das Neue der Erfindung besteht darin, daß bei einer derartigen Empfangseinrichtung die Empfangsenergie aus dem Niederfrequenz führenden Nebenzweig entnommen und dem Gitterkreis zugeführt wird.The invention relates to a device for amplified reception, both attenuated and non-attenuated Vibrations, in which in a receiving circuit with a vacuum tube in the anode circuit only a low frequency leading Side branch is provided. The novelty of the invention is that in such Receiving device receives the energy received from the secondary branch carrying the low frequency is removed and fed to the grid circle.
Die Zeichnung zeigt eine Ausfühfungsform der Erfindung. DieAntenne ι ist an die Spule 2 angeschlossen, die über das Abstimmittel 3 geerdet ist. Die Spule 2 liegt im Anodenkreis einer Vakuumröhre 4, welcher die Batterie 5The drawing shows an embodiment of the invention. The antenna ι is connected to the coil 2 connected, which is grounded via the tuning means 3. The coil 2 lies in the anode circuit a vacuum tube 4, which the battery 5
mit Parallelkondensator 6 enthält. Die Röhre 4 weist die Anode 7, das Gitter 8 und die Glühkathode 9 mit Heizbatterie 10 und Vorschaltwiderstand 11 auf. An dem Gitter 8 liegt der Schwingungskreis 12 mit Spule 13 und Kondensator 14. Die Spule 13 und der Kondensator 14 sind stufenweise oder stetig veränderlich. Wenn die Antenne 1 Schwingungen aufnimmt, so werden diese durch die gleichzeitig als Detektor und Verstärker wirkende Röhre 4 im Anodenkrei: hörbar gemacht, wenn in diesen Kreis ein Telephon mit ParaMelkondensator eingeschaltet wird.with parallel capacitor 6 contains. The tube 4 has the anode 7, the grid 8 and the hot cathode 9 with heating battery 10 and series resistor 11. On the grid 8 is the Oscillating circuit 12 with coil 13 and capacitor 14. The coil 13 and the capacitor 14 are gradually or continuously variable. When the antenna 1 picks up vibrations, in this way, they are transmitted through the tube 4, which simultaneously acts as a detector and amplifier in the anode circuit: made audible if a telephone with a ParaMel capacitor is in this circuit is switched on.
Aus dem Anodenkreis wird beispielsweise unter Vermittlung eines Transformators 15 Energie entnommen und dem Gitterkreis, z. B.. durch Einschaltung eines Kondensators 16, zugeführt. Das Telephon 17 ist zur Primären des Transformators 15 in Reihe geschaltet, wo-The anode circuit becomes 15 through the intermediary of a transformer, for example Energy taken and the grid circle, z. B .. by switching on a capacitor 16 supplied. The telephone 17 is connected in series to the primary of the transformer 15, where-
ao bei ein Kondensator 18 zu diesen beiden Teilen parallel gelegt ist. Der aus dem Telephon 17 und dem Transformator 15 bestehende Nebenzweig führt nur Niederfrequenz. Aus diesem Nebenzweige wird die niederfrequente Ener-ao at a capacitor 18 is placed in parallel to these two parts. The one on phone 17 and the secondary branch existing to the transformer 15 only carries low frequency. For this The low-frequency energy

Die Schaltung gewährt daher die Möglichkeit der an sich bekannten gleichzeitigen Hochfrequenz- und Niederfrequenz-Verstärkung.gie removed and fed to the grid circle. The circuit therefore grants the possibility the per se known simultaneous high-frequency and low-frequency amplification.
Noch eine weitere doppelte Wirksamkeit ist der Schaltung nach der Erfindung eigen. Die Schaltung wirkt nämlich bei entsprechender Einstellung des Glühstromes zugleich auch als Schwingungserzeugungsschaltung, so daß auch ungedämpfte Schwingungen durch Interferenz empfangen werden können, Die Hochfrequenzschwingungen verlaufen im Anodenkreise über den Kondensator 18 und im Gitterkreise über den Schwingungskreis 12. In einem besonderen Zweige, nämlich dem zum Kondensator 18 parallel liegenden Telephon, fließt nur Niederfrequenz. Für diese Niederfrequenz ist der Kondensator 14 praktisch nicht vorhanden. Sie wirkt unter Vermittlung der Spule 13 auf das Gitter 8.The circuit according to the invention has yet another double effect. the Circuit acts at the same time as when the glow current is set accordingly Oscillation generating circuit, so that undamped oscillations due to interference can be received, The high-frequency oscillations run over in the anode circuit the capacitor 18 and in the grid circles via the oscillating circuit 12. In a special one Branches, namely the telephone lying in parallel with the capacitor 18, only low-frequency flows. The capacitor 14 is practically non-existent for this low frequency. It acts on the grid 8 through the intermediary of the coil 13.
