  Einrichtung zur Verhinderung des Durchschlagens oder Zurückschlagens von Funken 
 EMI1.1 
 



   Bisher wurden die durch   Zurückschlagen oder Durchschlagen   von Funken und   Flammen   bewirkten Zündungen und Explosionen in Räumen, welche mit entzündlichen oder explosiblen Dämpfen, Gasen, Staub (beispielsweise Zelluloidstaub) oder dergl. erfüllt sind, dadurch vermieden, dass das   funken-oder nammenbildende Objekt (beispielsweise   der Elektromotor, der Gasmotor, die Lampe und   dergl.)   entweder eingekapselt wird oder aher Sicherheitsnetze (beispielsweise Davysche Grubenlampen) oder Wasservorlagen   bezw. Flüssigkeits-   abschlüsse vorgesehen werden. 
 EMI1.2 
 



   Alle diese Sicherheitsvorrichtungen haben den grossen Nachteil. dass sie in ihrer   Wirkung unzuverlässig   sind. 



   Ein Verkapselung wird leicht   undicht   und verhindert den Zutritt von   Luft zum   Objekte, was beispielsweise bei Elektromotoren infolge der starken Erhitzung grosse Unzu-   kömmlichkeiten herbeiführt.   
 EMI1.3 
 überhaupt unwirksam. Unter der   Einwirkung d@@ Atmospherilien   und durch eintretende chemische Reaktionen tritt eine Zerstörung des Netzes ein, sei es durch Rostbildung, sei es durch Bildung irgend einer Metallverbindung. Auch ist die   Abkühtungsnärhe   bei. Metall- 
 EMI1.4 
 eine sehr geringe. 



   Flüssigkeitsverschlüsse lassen sich nicht in allen   F'tillllll anbringen   und haben den 
 EMI1.5 
 schrot, und zwar am besten feinkörniger. 



   Die Metallkörner bieten den   Vorteil, blitz   sie zwischen   siel.   für den Durchgang nur kleine Zwischenräume freilassen, welche infolge der leichten Beweglichkeit der lose 
 EMI1.6 
 durch Zugabe von Metallkörnern leicht vergrösserhar ist, werden unter dem Verschlüsse entstehende Flammen oder Funken so   weit abgekühlt, dass   die   Flammenl) ildung nach   aussen   bezw. in das Behälterinnere verhindert nird.   



   Die Anordnung und   Konstruktion eines @@lchen Verschlusses gestaltet sich   sehr ein-   fach, beispielsweise bei Gasmotoren, indem   an dem Auspuff ein mit Schrot ganz oder teilweise   gefü iiltos Siphunrohr angeschlossen   wird.

 Explosionen möglich sind. 



   Um einige Beispiele von dem grossen Anwendungsgebiet der den Gegenstand der vorliegenden Erfindung bildenden Einrichtung zu geben, sei beispielsweise auf die Verwendung für Elektro- oder Gasmotoren in Bergwerksbetrieben, in mit Zelluloidstaub   verfüllten   Räumen, bei Betriebsaulagen mit leicht   entflammbaren   Mineralölen zum Abschluss von mit leicht entflammbaren Stoffen gefüllten Behältern usw. hingewiesen.

  Device to prevent the breakdown or flashback of sparks
 EMI1.1
 



   So far, the ignitions and explosions caused by the flashback or penetration of sparks and flames in rooms which are filled with flammable or explosive vapors, gases, dust (for example celluloid dust) or the like, have been avoided by the fact that the sparking or naming object (for example The electric motor, the gas engine, the lamp and the like.) Is either encapsulated or aher safety nets (for example Davy mine lamps) or water reservoirs or. Liquid seals are provided.
 EMI1.2
 



   All of these safety devices have the major disadvantage. that they are unreliable in their effect.



   Encapsulation is easily leaky and prevents air from reaching the object, which, for example, is very uncomfortable with electric motors due to the intense heating.
 EMI1.3
 ineffective at all. Under the influence of the atmospheres and the chemical reactions that occur, the network is destroyed, be it through the formation of rust or through the formation of any metal compound. The cooling is also close. Metal-
 EMI1.4
 a very low one.



   Liquid stoppers cannot be attached to all cases and have the
 EMI1.5
 shot, and preferably finer-grained.



   The metal grains offer the advantage of flashing them between you. Leave only small gaps for the passage, which due to the easy mobility of the loose
 EMI1.6
 is slightly larger by adding metal grains, the flames or sparks that develop under the closure are cooled down to such an extent that the flame is formed outside or inside the container is prevented.



   The arrangement and construction of a small closure is very simple, for example in the case of gas engines, in that a siphun pipe, which is completely or partially filled with shot, is connected to the exhaust.

 EMI2.1
 Explosions are possible.



   To give a few examples of the wide range of applications of the device forming the subject of the present invention, consider, for example, the use for electric or gas engines in mining operations, in rooms filled with celluloid dust, in operations with easily inflammable mineral oils to seal off easily inflammable substances filled containers etc. pointed out.
