    Entladungsgefäss   ans Glas. 



   Es ist bekannt, in Entladungsgefässen aus Glas Teile der Innenwandung mit Metallbelag zu versehen und diese als Elektroden zu verwenden. Durch eine das Gefäss von aussen umspülende Flüssigkeit können diese Stellen gekühlt werden, es wird dann die auf der dünnen Metallschicht entwickelte Wärme durch das Glas hindurch nach dem Kühlmittel abgeleitet. Praktische Versuche haben ergeben, dass bei dieser   Anordnung das Glas sehr ungleichmässig gekühlt wird und plötzlichen Temperaturschwankungen ausgesetzt ist, zumal wenn sich an der Oberfläche Gasblasen bilden, so dass einigermassen erhebliche Belastungen der   Elektroden stets zum Zerspringen der Wandungen führen.

   Dieser Übelstand soll erfindungsgemäss dadurch beseitigt werden, dass an der Grenzfläche des Glases gegen die Flüssigkeit eine die Wärme gutleitende Schicht angeordnet wird, durch die die gefährlichen Unregelmässigkeiten in der Kühlung ausgeglichen werden. Man kann zu diesem Zweck das Gefäss mit einer gut anliegenden Staniolschicht versehen oder. auch die in Betracht kommenden Stellen durch das Spritzverfahren auf chemischem oder galvanischem Wege mit einem geeigneten Metallbelag bedecken.

    Discharge vessel to the glass.



   It is known to provide parts of the inner wall of glass discharge vessels with a metal coating and to use them as electrodes. These areas can be cooled by a liquid that flows around the vessel from the outside, and the heat developed on the thin metal layer is then dissipated through the glass to the coolant. Practical tests have shown that with this arrangement the glass is cooled very unevenly and is exposed to sudden temperature fluctuations, especially when gas bubbles form on the surface, so that somewhat considerable stresses on the electrodes always lead to the walls cracking.

   According to the invention, this inconvenience is to be eliminated by arranging a layer which conducts heat well at the interface between the glass and the liquid and which compensates for the dangerous irregularities in the cooling. For this purpose, the vessel can be provided with a well-fitting layer of tin foil or. also cover the areas in question with a suitable metal covering by spraying chemically or galvanically.

PATENT-ANSPRUCH : Entladungsgefäss aus Glas, bei dem eine oder mehrere Elektroden aus einem metallischem Belag der Innenwand bestehen und durch Flüssigkeit von aussen gekühlt werden, dadurch gekennzeichnet, dass zur Verhinderung einer ungleichmässigen Erwärmung des Glases auf der Grenzfläche desselben gegen das Kühlmittel eine weitere metallische Schicht angeordnet ist. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: Discharge vessel made of glass, in which one or more electrodes consist of a metallic coating of the inner wall and are cooled by liquid from the outside, characterized in that a further metallic layer is arranged on the interface of the glass against the coolant to prevent uneven heating of the glass. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
