   Vorliegende Erfindung betrifft eine Feueranzeigenvorrichtung, die durch die ungleiche Geschwindigkeit der Ausdehnung von in zwei   Behättern eingeschlossenen   Gasen wirkt, von denen einer der umgebenden Luft eine im Vergleich zu seinem Rauminhalt grosse Oberfläche darbietet und dessen Inhalt rascher von der Wärme beeinflusst wird, als der Inhalt des anderen Behälters, was dadurch herbeigeführt werden kann, dass man den anderen   Behälter   mit einem Mantel versieht oder ihm eine solche Gestalt gibt, dass der Inhalt desselben von der Wärme nicht so rasch beeinflusst. wird ; man kann beispielsweise den anderen

 EMI1.1
 



   The present invention relates to a fire alarm device which acts through the unequal rate of expansion of gases enclosed in two containers, one of which presents a large surface area to the surrounding air compared to its volume and whose contents are more rapidly affected by heat than the contents of the other container, which can be brought about by providing the other container with a jacket or giving it such a shape that the contents of the same are not affected by the heat as quickly. becomes ; one can, for example, the other

 The drawing shows a fire alarm device in which an electrical line is closed and in FIG. 2 one in which an electrical line is interrupted.



   In Fig. 1, a and b are pipes containing gases, of which a the outside air is one in

 the wires f and y are normally in contact with your mercury. In the event of a sudden increase in temperature, the contents of tube a expand faster than that of tube b, and the mercury in tube d comes out of contact with wire g, whereby the line is interrupted. In Fig. 2 the tubes a, b are almost

  However, these tubes can also be filled with air or another gas, as in the device shown in FIG. 1, and the latter could also be partially filled with alcohol

 If necessary, a small amount of creosote or similar liquid can be introduced into the tube to prevent the mercury from oxidizing.
