mittierend einsetzen, wie das beim Zeichengebet) der Fall ist, so kann dieser Umstand mit Vorteil dazu verwendet werden, dass bei zweckmässiger Einstellung des Apparates der Relaisstrom derselbe bleibt, ob der Sender ausser Betrieb ist oder seine genaue Wellenlänge einhält.
Zum Aufzeichnen von drahtlosen Signalen dient die Anordnung gemäss Fig. 4. In diesem Falle ist die Kondensatorbelegung I als eine schwingende Zunge ausgebildet, die durch einen Elektromagneten O beeinflusst wird. Diese Zunge kann aperiodiselh, wie eine Telephonmembran sein oder kann eine der

induktive Kopplung des Kreises A mit der Antenne oder mit dem Verstärkerkreise erfolgen.
Fig. 5 stellt die Anordnung in dieser Anwendung dar. Hier werden die verstärkten Hochfrequenzsignale dem Gitte und der Kathode einer Elektronenröhre P zugeführt, deren Anode und Kathode mit der Anode und Kathode der Röhre Q des Kreises A verbunden sind. Durch diese Anordnung rufen

PATENT-ANSPRÜCHE :
1. Anordnung zur Frequenz- und Spannungsregelung bzw. zur Wahrnehmbarmachung und Aufzeichnung von drahtlosen Signalen mit zwei aufeinander abgestimmten Schwingungskreisen und mit einem mit denselben gekoppelten, unabgestimmten Schwingungskrebe in Differentialschaltung, dadurch gekennzeichnet, dass bei Frequenzschwankungen eines der beiden abgestimmten Schwingungskreise in dem nicht abgestimmten Schwingungskreise ein Relais od. dgl. zur Ausgleichung der Frequenz- änderung betätigt wird.

used in a mediating manner, as is the case with the sign prayer), this fact can be used to advantage that, with appropriate setting of the apparatus, the relay current remains the same whether the transmitter is out of operation or adheres to its exact wavelength.
The arrangement according to FIG. 4 is used to record wireless signals. In this case, the capacitor assignment I is designed as a vibrating tongue which is influenced by an electromagnet O. This tongue can be aperiodic, like a telephone membrane, or can be one of the

inductive coupling of the circuit A with the antenna or with the amplifier circuit.
Fig. 5 shows the arrangement in this application. Here the amplified high-frequency signals are fed to the grid and cathode of an electron tube P, the anode and cathode of which are connected to the anode and cathode of the tube Q of the circuit A. Call through this arrangement

selective, registered reception can be used.
PATENT CLAIMS:
1. Arrangement for frequency and voltage regulation or for making wireless signals perceptible and recording with two coordinated oscillation circuits and with a non-coordinated oscillation circuit coupled with the same in differential circuit, characterized in that in the event of frequency fluctuations one of the two coordinated oscillation circuits in the non-coordinated oscillation circuit a relay or the like is actuated to compensate for the frequency change.
