Description

AUSGEGEBEN AM 19. JULI 1919ISSUED ON JULY 19, 1919

Beim Betriebe von Unterwassersirenen hat sich gezeigt, daß es für die Schallbildung und -wirkung von großer Wichtigkeit ist, ein Austreten von Luft oder sonstigen Gasen aus der Betriebsflüssigkeit beim Durchgang derselben durch die Sirenenanlage, insbesondere die Schallöffnungen der Sirene, möglichst zu vermeiden. Das Bestreben geht dabei dahin, das Entstehen von Luft- oder Gasbläschen im BetriebswasserWhen operating underwater sirens it has been shown that it is responsible for sound generation and -effect is of great importance, a leakage of air or other gases from the Operating fluid when it passes through the siren system, in particular the sound openings the siren to avoid if possible. The endeavor goes to the emergence of air or gas bubbles in the process water

Die Erfindung bezieht sich nun auf solche Unterwassersirenenanlagen, bei denen das Betriebsmittel einen geschlossenen Kreislauf vollführt und bezweckt, den erwähnten Übelstand auch in diesem Falle zu vermeiden bzw. den Kreislauf dem erstrebten Zweck nutzbar, zu machen. Gemäß der Erfindung wird dies dadurch bewirkt, daß eine Betriebsflüssigkeit verwendet wird, die auf künstlichem Wege vor der Einfüllung in die Anlage nach Möglichkeit luftfrei gemacht ist. Der Kreislauf des Betriebstaittels selbst kann in der Weise erfolgen, wie dies bereits bekannte Einrichtungen zeigen.' Dabei muß natürlich Sorge getragen werden, daß die Betriebsflüssigkeit niemals und nirgends mit der Außenluft in Berührung kommt. Für die Entlüftung selbst können irgendwelche geeignete Verfahren, die in der Technik bereits üblich sind, angewendet werden.The invention now relates to such underwater siren systems in which the operating means carries out a closed cycle and aims to remedy the aforementioned evil in this case, too, to avoid or to use the cycle for the intended purpose do. According to the invention, this is effected in that an operating fluid is used, which is artificially before being filled into the system if possible is made air-free. The cycle of the operating resource itself can take place in such a way that as already known institutions show. ' Care must of course be taken that the operating fluid never and nowhere comes into contact with the outside air. For The venting itself can be any suitable method that is already in the art are common.

Das Verfahren weist den Vorzug auf, daß besondere Einrichtungen zum dauernden Entlüften frischen Betriebswassers mit ihrem Raumund Kraft bedarf vermieden werden.The method has the advantage that special devices for permanent venting fresh process water with its space and power requirements can be avoided.
