Description

Vorrichtung zum Anzeigen von Gasen bzw. schlagenden Wettern mittels vorgeheizter katalytischer Körper. Die Erfindung betrifft eine Vorrichtung zum Anzeigen von schlagenden Wettern mittels eines vorgeheizten, katalytischen Körpers, bei welcher der letztere unter Zwischenschaltung einer Dosenmernbran auf einen Umschalter wirkt, der entweder den Stromkreis mit dem Heizwiderstand des katalytischen Körpers oder den Stromkreis mit dem akustischen und optischen Signal einschaltet. In der Zeichnung ist die Schlagwetteranzeigevorrichtung dargestellt. In derselben speist eine Akkumulatorenbatterie A von 6Volt, 2oAmperestunden einen Widerstand aus Nikelindraht R von 6 Ohrn. Dieser WiderstandR dient als ein Heizkörper für einen katalytischen KörperH, bestehend aus einer Asbestplatte, die mit Platinehlorid getränkt ist und zu Platinasbestschwamm reduziert wurde. . Der katalytische KörperH wird dauernd durch den HeizkörperR erwärmt. Für eine automatische Regulierung der Vorwärmung und für ein optisches sowie akustisches Signal dient eine Kupferdose mit einer WellblechmembranD, an deren Membran ein Umschalthebel U sitzt, der hiervon isolierte Kontakte I und II schließt und öffnet. Wird der vorgewärmte katalytische Körper H durch ein Drahtnetz F einströniende Grubengase beeinflußt, so wird die Wärme im katalyeischen Körper bis zur dunkelroten Glut gesteigert. Zur Verhinderu-ng der weiteren Glutsteigerung ist der katalytische KörperH in einem doppelten feinen SiebnetzS eingebettet, durch welches eine starke Abkühlung der Gase herbeigeführt wird, so daß eine Zerstörung des katalytischen Körpers H nicht erfolgen kann. 1.-ler kataly-tische Körper H in seinem Schutzsiebnetz S ist an einer Kupferdose D, die vorn die Membran hat, an der Rückwand befestigt, und zwar derart, daß die erzeugende Wärme die in der DoseD eingeschlossene Luft ausdehnt, wodurch die Membran dieser DoseD vorgerückt wird und diese den Umschalthebel U von dein 'Vorwärmekontakt K, al-,bebt unter Ausschaltung des Heizkörpers R. An dessen Stelle wird der Kontakt K, des optischen und akustischen Signals L und S sc. lange geschlossen, als die Gase den katalytischen Körper H in einer bestimmten Temperaturhöhe erhalten. Werden die Grubengase so schwach, daß ihr Einfluß auf den katalytischen Körper H Null ist, so zieht sich die abgekühlte Luft in der verschlossenen DoseD zusammen, und die Membran zieht den Umschalthebel U von dem Signalkontakt K, des Signalstromkreises A, D, U, K, S, L, Sch, A zurück auf den Kontakt K, des Vorwärmerstromkreises A, D, U, K, R, Sch, A für den katalytischen Körper H. Somit ist der Gasinelder für eine weitere Gasausströmung wieder - selbsttätig vorbereitet. Zur Sicherheit an den Kontakten K, und K, ist ein Kondensator C Von io Mikrofarad eingeschaltet, welcher der Unterbrecherstelle die kleinen Kontäktfunken entzieht. Ein Ausschalter Sch dient sowohl zum Ausschalten des Apparates wie zur Kontrolle für die Zuverlässigkeit. Vor den akustischen und optischen Signalen S und L sind zur Sicherung der Explosiomsgefahr ebenfalls noch Dralitnetze F angeordnet. Das optische Signal L ist noch mit einem Reflektor F versehen.Device for displaying gases or striking weather by means of preheated catalytic bodies. The invention relates to a device for displaying beating weather by means of a preheated, catalytic body, in which the latter acts with the interposition of a can membrane on a changeover switch that switches on either the circuit with the heating resistor of the catalytic body or the circuit with the acoustic and optical signal . In the drawing, the firedamp display device is shown. In the same, an accumulator battery A of 6 volts, 20 ampere hours feeds a resistance made of nickel wire R of 6 ears. This resistor R serves as a heating element for a catalytic body H consisting of an asbestos plate soaked with platinum chloride and reduced to platinum asbestos sponge. . The catalytic body H is continuously heated by the heater R. A copper box with a corrugated sheet metal membrane D , on the membrane of which sits a switch lever U, which closes and opens contacts I and II, is used for automatic regulation of the preheating and for an optical and acoustic signal. If the preheated catalytic body H is influenced by mine gases flowing in through a wire mesh F, the heat in the catalytic body is increased to a dark red glow. To prevent a further increase in embers, the catalytic body H is embedded in a double fine mesh screen S, through which a strong cooling of the gases is brought about so that the catalytic body H cannot be destroyed. 1. The catalytic body H in its protective screen mesh S is attached to a copper can D, which has the membrane in front, on the rear wall, in such a way that the heat generated expands the air enclosed in the DoseD, whereby the membrane of this DoseD is advanced and this moves the switch lever U from your 'preheating contact K, al-, trembles, switching off the heating element R. In its place, the contact K, the optical and acoustic signal L and S sc. Is closed for a long time as the gases pass the catalytic Get body H at a certain temperature level. If the mine gases become so weak that their influence on the catalytic body H is zero, the cooled air in the closed can D contracts and the membrane pulls the switch lever U from the signal contact K, the signal circuit A, D, U, K , S, L, Sch, a to the contact K, the Vorwärmerstromkreises a, D, U, K, R, Sch, a for the catalytic body H. Thus, the Gasinelder for a further gas leakage is back again - automatically prepared. For safety at the contacts K and K, a capacitor C of io microfarad is switched on, which removes the small contact sparks from the breaker point. An off switch Sch is used both to switch off the device and to control the reliability. In front of the acoustic and optical signals S and L, twisted meshes F are also arranged to protect against the risk of explosion. The optical signal L is also provided with a reflector F.
