Description

Alarm- und Anzeigevorrichtung für das Auftreten gesundheitsschädlicher Gase. Es sind Vorrichtungen. bekannt, die das Ausströmen von Gas aus Rohrleitungen sowie allgemein das Auftreten gesundheitsschädlicher Gase anzeigen. Die einen benutzen dabei die Volumenveränderung von Körpern im glühenden Zustande, die andern z. B. die Verdunkelung einer Lichtquelle infolge Schwärzung gewisser Metallmischungen. -Gegenstand der Erfindung ist eine ebensolche Anzeigevorrichtung, nur ist sie gegenüber dem Bekannten bedeutend einfacher gehalten. Auch die Wirkungsweise ist anders, wodurch z. B. gewisse Vorbedingungen der bekannten Einrichtungen, die ein Versagen der Vorrichtung bedingen, ausgeschaltet werden.Alarm and display device for the occurrence of harmful substances Gases. They are devices. known to the leakage of gas from pipelines as well as generally indicate the occurrence of harmful gases. Use the one while the volume change of bodies in the glowing state, the other z. B. the darkening of a light source as a result of the blackening of certain metal mixtures. -The subject of the invention is such a display device, only it is opposite kept much simpler to the known. The mode of action is also different, which means z. B. certain preconditions of the known devices that a failure of the device condition to be turned off.

In der Zeichnung ist ein Ausführungsbeispiel dargestellt. Es bedeutet Fig. = einen Deckel i mit Öffnungen 2, dessen Schnitt in Fig. 2 wiedergegeben ist. Dieser Deckel wird auf eine Grundplatte g (Fig. 3) aufgesetzt. Fig. q. stellt den Schnitt durch die Vorrichtung bei der Ebene C-D dar. Auf der Grundplatte im Kasten befinden sich zwei Metallschienen 3 mit Reitern 4. In diese werden die katalytischen Körper 5 eingesteckt, und zwar je nach Auswahl, welches Gas angezeigt werden soll. Die beiden Metallschienen sind durch eine galvanische Batterie 6 mit einem Relais 7 verbunden. Durch dieses kann die Anzeigevorrichtung 8, die hier als Klingel dargestellt ist, betätigt werden.An exemplary embodiment is shown in the drawing. It means Fig. = A cover i with openings 2, the section of which is shown in FIG. This cover is placed on a base plate g (Fig. 3). Fig. Q. represents the Section through the device at level C-D. On the base plate in the box there are two metal rails 3 with tabs 4. In these are the catalytic Body 5 inserted, depending on the selection of which gas is to be displayed. The two metal rails are powered by a galvanic battery 6 with a relay 7 connected. This allows the display device 8, shown here as a bell is to be operated.

Die Wirkungsweise der Vorrichtung ist folgende Durch die Einwirkung der Gase, die durch . die Öffnungen 2 in die Vorrichtung dringen, wird der katalytische Körper 5 selbt, z. B. salzsaures Kupferchlorür, derart beeinflußt, daß sich sein eigener elektrischer Widerstand verändert. Hierdurch ist die Batterie 6 in der Lage, das Relais 7 au erregen, wordurch dessen Anker den Stromkreis der Anzeigevorrichtung schließt.The mode of operation of the device is as follows of gases passing through. the openings 2 penetrate into the device, becomes the catalytic one Body 5 itself, e.g. B. hydrochloric acid copper chloride, so influenced that its own electrical resistance changed. As a result, the battery 6 is able to the relay 7 au energize, whereby its armature the circuit of the display device closes.

Um die Vorrichtung wieder betriebsfähig zu machen, wird der verbrauchte Körper 5 durch einen neuen ersetzt. Es wird sich nicht immer sofort erkennen lassen, welcher Körper verbraucht ist. Es werden daher alle Körper entfernt, wodurch die Anzeigevorrichtung ausgeschaltet wird. Indem nun die Körper nacheineinander wieder eingesetzt werden, wird bei Betätigung der Anzeigevorrichtung der verbrauchte Körper sofort erkannt werden.In order to make the device operational again, the used up Body 5 replaced with a new one. It won't always be immediately apparent which body is used up. Therefore all bodies are removed, whereby the Display device is turned off. By now putting the bodies one after the other again are used, when the display device is operated, the used body can be recognized immediately.

PATENT-ANSPRÜCHE: i. Alarm- und Anzeigevorrichtung für das Auftreten gesundheitsschädlicher Gase, dadurch gekennzeichnet, daß durch Einwirkung der anzuzeigenden Gase katalytische Körper selbst, z. B. salzsaures Kupferchlorid, in ihrer Konsistenz derart beeinßußt werden, daß sie ihren eigenen elektrischen Widerstand ändern. PATENT CLAIMS: i. Alarm and display device for the occurrence Harmful gases, characterized in that by the action of the to be displayed Gases catalytic bodies themselves, e.g. B. hydrochloric acid copper chloride, in its consistency are so influenced that they change their own electrical resistance. 2. Vorrichtung nach Anspruch i, dadurch gekennzeichnet, daß durch Parallel -schalten verschiedener katalytischer Körper eine Vorrichtung zum Anzeigen verschiedener Gase verwendet werden kann.2. Device according to claim i, characterized in that by connecting in parallel different catalytic bodies a device for displaying different gases can be used.
