  Verfahren zum Verschliessen des Hohlraumes von   Porzellanvakuumgefässen.   
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 Luftpumpe bereits erfolgt ist, was die Vornahme eines Abschmelzprozesses verlangt, der ohne kreisende Flamme vor sich gehen kann. 



   Die Erfindung gestattet die Herstellung von sehr haltbaren Vakuumgefässen, deren Vakuum unbegrenzt lange erhalten bleibt und welche daher dauernd sowohl zur Aufnahme tiefkalter Flüssigkeiten, wie flüssiger Luft, als auch zum Aufbewahren heisser Füllungen, wie z. B. von Speisen und Getränken, benutzt werden können.

  Method for closing the cavity of porcelain vacuum vessels.
 EMI1.1
 

 <Desc / Clms Page number 2>

 Air pump has already taken place, which requires the implementation of a melting process that can take place without a rotating flame.



   The invention allows the production of very durable vacuum vessels, the vacuum of which is maintained indefinitely and which therefore permanently both for holding cryogenic liquids, such as liquid air, as well as for storing hot fillings, such as. B. of food and drinks can be used.

PATENT-ANSPRUCH : Verfahren zur Herstellung von Vakuumgefässen aus Porzellan mit Porzellanröhrchenansatz für die Evakuierung, dadurch gekennzeichnet, dass das Gefäss an die Pumpe unter Zwischenschaltung eines Glasrohres angeschlossen wird, und dass nach erfolgter Evakuierung zuerst das Glasrohr in an sich bekannter Weise abgeschmolzen wird, und dass dann erst die Abschmelzung des Porzellanansatzröhrchens vorgenommen wird, indem man das Gefäss oder die Abschmelzflamme rotieren lässt, so dass die Flamme um das abzuschmelzende Rohr beim Abschmelzen einen Kreis beschreibt. PATENT CLAIM: A process for the production of vacuum vessels made of porcelain with a porcelain tube attachment for evacuation, characterized in that the vessel is connected to the pump with a glass tube interposed, and that after the evacuation has taken place, the glass tube is melted off in a known manner, and then only the Melting the porcelain tube is done by rotating the vessel or the melting flame so that the flame describes a circle around the tube to be melted.
