Alarmapparat zur Verhütung von Explosionen und Vergiftungen durch Gase.
A und B sind zwei Glaskugeln von gleichem Volumen, welche durch eine feinkalibrige (glasröhre miteinander in Verbindung stehen. Diese Röhre ist bis x und xl mit Quack- silber D gefüllt. Die Kugel A trägt bei C einen Mantel von Platinmoor und ist von einem dichten Drahtnetze H umhüllt. Die Kugel B hat zwei Platinpole E und F eingeschmolzen, welche mit einem Läuteapparat K in elektrisch-leitender Verbindung stehen.
Strömt in einem geschlossenen Räume, z. B. einem Tunnel, Gas ans, so erwärmt es. zum Apparat (der an der Decke angebracht wird) gelangt, den Mantel C durch Absorption, die Luft in. 4 dehnt sich aus und treibt das Quecksilber in die Kugel B. Dort verbindet dieses die tx' ten Pole E und F, der Strom des Läutewerkes wird geschlossen und die Alarmglocke t'rtiint. Wird der Gaszufluss nicht sogleich abgestellt, so verhindert das Drahtnetz H eine FortpHanynng der Entzündung des Gases nach aussen, falls das Platinmoor sich bis zur Entzündungstemperatur erwärmen sollte.
Der ähnlichen Apparaten anhaftende Mangel, dass diese auch da@n alarmieren, wenn noch kein Gas ausströmt, dass nämlich eine Temperaturerhöhung der Umge@ung allein

Alarm device for the prevention of explosions and poisoning by gases.
A and B are two glass spheres of equal volume, which are connected to one another by a fine-caliber (glass tube. This tube is filled to x and xl with quack silver D. At C, sphere A has a coat of platinum moor and is thick Enclosed wire mesh H. The ball B has two platinum poles E and F melted in, which are in electrically conductive connection with a ringing device K.
Flows in an enclosed space, e.g. B. a tunnel, gas ans, it heats up. reaches the apparatus (which is attached to the ceiling), the jacket C by absorption, the air in. 4 expands and drives the mercury into the sphere B. There it connects the tx'th poles E and F, the current of the The bell closes and the alarm bell t'rtiint. If the gas supply is not shut off immediately, the wire mesh H prevents the ignition of the gas from continuing to the outside if the platinum bog should warm up to the ignition temperature.
The deficiency inherent in similar devices, that they also alarm when no gas is flowing out, that is, a temperature increase in the environment alone
EMI1.1
trigger an alarm.
