Description

Einrichtung zur Beseitigung störender Einwirkungen in den Abstimmkreisen. bei Unterwasserschallempfangsapparaten. Es ist bekannt, daß man zur Beseitigung von störenden Geräuschen in den Empfangsanlagen für Unterwasserschallsignale elektrische Abstimmkreise verwendet, die auf die Frequenz des jeweils aufzunehmenden Tones albgestimmt sind. Diese Abstimmkreise bestehen aus einer Selbstinduktion und Kapazität, die gewöhnlich in dem Schaltkasten der Empfangseinrichtung untergebracht werden. Der Empfangskasten selbst befindet sieh in der Signalzentrale. Durch diese führen häufig wechselstromführende Kabel, die naturgemäß die Abstimmspule induzieren, besonders stark, wenn die Frequenz des äußeren Wechselstromes zufällig übereinstimmt mit der Frequenz der aufzunehmenden Signale. Iin Einpfangstelephon macht sich dieses sogenannte Übersprechen als dauerndes Singen bemerkbar; das sich den Signalen überlagert und diese mehr oder weniger stark verwischt, so daß sie oft überhaupt nicht aufzunehmen sind.Device for eliminating disruptive effects in the voting circles. for underwater sound receivers. It is known that one can get rid of it of disruptive noises in the receiving systems for electrical underwater sound signals Tuning circles are used that are tuned to the frequency of the tone to be recorded are. These tuning circles consist of a self-induction and a capacity that usually be housed in the switch box of the receiving device. Of the The reception box itself is located in the signal center. Lead through this often AC cables that naturally induce the tuning coil, especially strong when the frequency of the external alternating current happens to coincide with that Frequency of the signals to be recorded. This so-called Crosstalk noticeable as constant singing; that is superimposed on the signals and these are more or less blurred, so that they often cannot be absorbed at all are.

Die vorliegende Erfindung bezweckt die Vermeidung dieses Übelstandes. Dieses wird dadurch erreicht, daß man die Abstimmspule in der Empfangsapparatur beweglich anordnet und sie so stellt, daß die störende Induktion ein Minimum erreicht. Zur t,rläuterung des Erfindungsgedankens ist auf der Zeichnung ein Ausführungsbeispiel dargestellt. Mit a ist die Abstimmspule bezeichnet, die .beweglich in den Vertikallagern c und d eines Empfangsapparates b gelagert ist und durch einen Knopf g um ihre Vertikalachse gedreht werden kann. Der Kasten b ruht . seinerseits beweglich in den H-örizontallagern e und f und kann gleichfalls durch eine Handhabe gi gedreht werden.The present invention aims to avoid this inconvenience. This is achieved by arranging the tuning coil to be movable in the receiving apparatus and setting it in such a way that the interfering induction reaches a minimum. To explain the concept of the invention, an exemplary embodiment is shown in the drawing. The tuning coil is denoted by a, which is movably mounted in the vertical bearings c and d of a receiving apparatus b and can be rotated about its vertical axis by a button g. Box b is at rest. in turn movable in the H-örizontallager e and f and can also be rotated by a handle gi.

Aus der Darstellung ergibt sich, daß der Spule eine beliebige räumliche Lage erteilt werden kann, so daß ihre Einstellung jederzeit so ausführbar ist, wie es durch die auftretenden störenden Feldwirkungen erforderlich wird.From the illustration it can be seen that the coil has any spatial Location can be granted so that their setting can be carried out at any time as it becomes necessary due to the disturbing field effects that occur.
