Description

Der Gegenstand der Erfindung besteht in einer elektrischen Abstimmeinrichtung, die wenigstens aus zwei Systemen besteht, von denen das eine beweglich angeordnet ist.
Bei radiotelegraphischen Stationen kann die Aufgabe bestehen, um eine bestimmte Resonanzwelle herum innerhalb gewisser Grenzen dauernd suchen zu müssen, so daß die Abstimm-. einrichtung, die im wesentlichen aus einemThe subject of the invention consists in an electrical tuning device which consists of at least two systems, one of which is movably arranged.
In the case of radio telegraphic stations, the task can be to have to search around a certain resonance wave within certain limits, so that the tuning. device, which essentially consists of a

ίο veränderlichen Kondensator oder einer Selbstinduktion besteht, innerhalb dieser Grenzen geändert werden1 muß, der Bedienungsmann also dieses Organ dauernd zu bedienen hat. Dies wird nach dem Gegenstand der Erfindung dadurch vermieden, daß die Abstimmeinrichtung (Kondensator oder Variometer) um einen bestimmten Resonanzwert für die auf-. zunehmende Welle innerhalb gewisser Grenzen mechanisch bewegt wird, indem das bewegliche System beispielsweise mit einem Gewicht oder mit einer Unruhe versehen ist, die nach einmal erfolgtem Anstoß das bewegliche System entsprechend dem Ausschlag des Gewichtes bzw. der Feder nach beiden Seiten des Resonanzwertes periodisch ändert, so daß innerhalb dieses Bereiches durch periodische Einstellung bzw. Änderung des Kondensators bzw. Variometers empfangen werden kann. Die Anordnung kann selbstverständlich auch derart ausgeführt werden, daß das periodische Pendeln des beweglichen Systems um einen bestimmten Wert herum durch ein aufziehbares Laufwerk erfolgt. Die Feststellung des Kondensators bzw. Variometers auf einen gewünschten Wert wird durch eine am Apparat vorgesehene 3S Feststellvorrichtung bzw. Klemmvorrichtung oder eine Feststellvorrichtung am Laufwerk vorgenommen. Außerdem kann die Abstimm einrichtung mit begrenzenden Anschlägen versehen sein, die verstellbar sind und den Bereich -des pendelnden Kondensators bzw. Variometers begrenzen; auch kann sie in bekannter Weise mit einer Skala versehen sein, die den Wert für die Resonanzwelle bzw. den zu umfassenden Bereich abzulesen gestattet.ίο there is a variable capacitor or a self-induction, must be changed within these limits 1 , so the operator has to operate this organ continuously. This is avoided according to the object of the invention in that the tuning device (capacitor or variometer) to a certain resonance value for the up. increasing wave is mechanically moved within certain limits, in that the moving system is provided with a weight or a restlessness, for example, which changes the moving system periodically according to the deflection of the weight or the spring on both sides of the resonance value after an impact, so that can be received within this range by periodically setting or changing the capacitor or variometer. The arrangement can of course also be carried out in such a way that the periodic oscillation of the movable system around a certain value takes place by means of a pull-out drive. The capacitor or variometer is set to a desired value by a 3 S locking device or clamping device provided on the apparatus or a locking device on the drive. In addition, the tuning device can be provided with limiting stops that are adjustable and limit the range of the oscillating capacitor or variometer; it can also be provided in a known manner with a scale which allows the value for the resonance wave or the range to be encompassed to be read off.

Ein derartiger Apparat eignet sich insbesondere für die Benutzung in Stationen, mit Schwebungsempfang, bei welchen der zu empfangende Ton in der Resonanzlage nicht wahrnehmbar ist, da eine Interferenz der Schwingungen nur außerhalb der Resonanz beider Frequenzen (der ankommenden und der auf der. Empfangsseite erzeugten) eintritt.Such an apparatus is particularly suitable for use in stations, with beat reception, in which the tone to be received is not in the resonance position is perceptible, since an interference of the vibrations only outside of the resonance of both frequencies (the incoming and the one generated on the receiving side) occurs.
