Description
Die Empfänger zur Beobachtung von Schallwellen unter Wasser werden unter Wasser eingebracht und müssen natürlich mit dem Beobachtungsstand durch eine (meist elektrische) Leitung in Verbindung stehen. Durch diesen Umstand wird der Mangel hervorgerufen, daß von dem Empfänger auch Nebengeräusche vermittelt werden, die eben aus seiner Verbindung mit der Leitung sich ergeben, welche selbstThe receivers for observing sound waves under water are placed under water and must of course be connected to the observation post by a (mostly electrical) line. Through this The fact that the receiver also transmits background noise is caused by the fact that which result from its connection with the line, which itself
ίο bei geringer Wasserbewegung irs Schlackern gerät, was die Nebengeräusche verursacht.ίο with little water movement irs slagging what is causing the background noise.
Aufgabe der Erfindung ist es, diesem Mangel abzuhelfen, was dadurch erreicht wird, daß die Kabelleitung an einem Gestell starr befestigt ist, an dem der Empfänger federnd gelagert ist. In der Zeichnung ist ein Ausführungsbeispiel einer solchen Einrichtung schematisch im Aufriß dargestellt. Der Empfänger bekannter beliebiger Konstruktion d, in den die Kabelleitung g durch einen Hals f tritt, wird von dieser akustisch in der Weise isoliert, daß man die Verbindung zwischen diesen beiden abfedert. In dem gewählten Ausführungsbeispiel sind zu diesem Zwecke zwei Maßnahmen getroffen: Einmal ist der Empfänger durch Federn e zwischen zwei Gestellplatten α und b gelagert, die miteinander durch Streben c in fester Verbindung stehen. Außardem ist das Kabel g an der oberen Platte α durch eine Schelle i so gefaßt, daß zwischen dieser Schelle und dem Empfänger eine Ausbiegung k gebildet wird. Die Schelle' i erreicht den doppelten Zweck:The object of the invention is to remedy this deficiency, which is achieved in that the cable line is rigidly attached to a frame on which the receiver is resiliently mounted. In the drawing, an embodiment of such a device is shown schematically in elevation. The receiver of any known construction d, into which the cable line g passes through a neck f , is acoustically isolated therefrom in such a way that the connection between these two is cushioned. In the chosen embodiment, two measures are taken for this purpose: On the one hand, the receiver is supported by springs e between two frame plates α and b , which are firmly connected to one another by struts c. In addition, the cable g is gripped on the upper plate α by a clamp i in such a way that a bend k is formed between this clamp and the receiver. The clamp 'i achieves two purposes:
1. die Abdichtung des Halses f von dem Zuge der Leitur.g zu entlasten, und1. to relieve the seal of the neck f from the train of Leitur.g, and
2. den starren Zusammenhang zwischen Schalleitung und Schallempfänger aufzuheben und so die Übertragung von störenden Nebengeräuschen möglichst zu verhindern.2. To remove the rigid connection between sound conductors and sound receivers and thus to prevent the transmission of annoying background noises as far as possible.
Zur Erreichung des angestrebten Zweckes genügt es ebenso, wenn man statt der dargestellten vier Federn nur zwei, und infolgedessen auch nur eine Gestellplatte α benutzt; auch können statt der dargestellten Federn Gummibänder oder Gummischläuche oder sonstige^akustisch isolierende Materialien verwendet werden.To achieve the intended purpose, it is also sufficient if, instead of the four springs shown, only two springs are used, and consequently only one frame plate α is used; instead of the springs shown, rubber bands or rubber hoses or other acoustically insulating materials can also be used.
