Description

Apparat zum selbsttätigen Anzeigen des Ansammelns explosionsgefährlicher und giftiger Gase in Wohnräumen u. dgl. Den Gegenstand der Erfindung bildet ein Apparat zum Zweck des Anzeigens ausströmender Gase u. dgl. in geschlossenen Räumen. Der Apparat besteht aus zwei ausbalanciert aufgehängten Glockenschalen, von denen eine einen sich beim Auftreten von Zimmergasen selbsttätig erhitzenden Körper, wie z. B. ein Platinschwamm o. dgl., trägt, der dann die im Glockeninnern befindliche Luft ausdehnt und dabei den Stromkreis einer Alarmglocke schließt.Apparatus for automatically indicating the accumulation of explosive hazards and toxic gases in living spaces and the like Apparatus for the purpose of indicating escaping gases and the like in closed rooms. The apparatus consists of two balanced bell shells, one of which a body that heats up automatically when gas occurs in the room, such as z. B. a platinum sponge o. The like., Which then located inside the bell Air expands and thereby closes the circuit of an alarm bell.

Wie in der Zeichnung ersichtlich ist, sind an einem auf einem Kontaktstift ausbalancierten Wagebalken zwei oberhalb geschlossene Glockenschalen =, 2 aufgehängt. Im Mittelpunkt der einen Schale i ist ein katalytischer Körper 3, wie Platinschwamm o. dgl., zweckmäßig angeordnet, während in der Glocke z ein Ausgleichgewicht q. angeordnet ist, das ebensoviel Volumen besitzt wie der Platinschwamm, um bei einem Zimmertemperaturwechsel einen Ausgleich zum letzteren zu erzielen. Die Glocken i, 2 sind von feinen Metallnetzen 5, 6 abgeschlossen, von denen das Netz 5 nach dem Prinzip der Davyschen Sicherheitslampe eine Entzündung der Gase in der Glocke i verhindern soll, während das Netz 6 nur zum Ausgleich des Gewichts der Glocke 2 dient, um eine frühere Veränderung des Körpers q gegenüber dem Körper 3 beim Eintreten von Temperaturwechsel zu verhindern. Durch die beim Auftreten von Zimmergasen in die Glocke i eindringenden Gase wird der Körper 3 erhitzt und verringert in der Glocke z dadurch die Luftmenge und bringt die Glocke .2 zum Sinken, wobei die in der Wagebalkenmitte angeordnete Zunge 7 ausschlägt und durch Berührung des Kontaktes 8 den Stromkreis zu einer Alarmglocke oder auch zu einem Dauerschalter schließt. Bei einem späteren wieder in den beiden Glocken i, 2 entstandenen Luftausgleich kehrt die Zunge 7 in die Anfangsstellung zurück, so daß der Apparat, ohne bedient zu werden, wieder für weitere Meldezwecke gebrauchsfähig ist.As can be seen in the drawing, one is on a contact pin balanced balance beam two bell shells closed above =, 2 suspended. In the center of the one shell i is a catalytic body 3, such as a platinum sponge o. The like., expediently arranged, while in the bell z a balance weight q. is arranged, which has as much volume as the platinum sponge to with a Room temperature changes to compensate for the latter. The bells i 2 are closed by fine metal nets 5, 6, of which the net 5 after the Principle of the Davy safety lamp an ignition of the gases in the bell i is intended to prevent, while the network 6 only to compensate for the weight of the bell 2 serves to indicate an earlier change in body q compared to body 3 upon entering to prevent temperature changes. Due to the occurrence of room gases in the bell i penetrating gases is heated and decreased in the body 3 Bell z thereby the air volume and brings the bell .2 to sink, whereby the in the tongue 7 arranged in the center of the balance beam deflects and by touching the contact 8 closes the circuit to an alarm bell or to a permanent switch. In the case of a later air equalization again in the two bells i, 2 the tongue 7 returns to the initial position so that the apparatus is operated without to become usable again for further reporting purposes.
