   negativen Aussenleiter   ; in dem Nulleiter liegt zugleich ein Regelwiderstand f, der zur Regelung der Temperatur des Oxyds dient. Der Strom geht zwischen den beiden Aussenleitern durch das ionisierte Vakuum über. 



   Wenngleich die Verwendung von Gleichstrom in erster Linie für dieses Verfahren in Betracht   kommt,   so   ist es doch auch möglich, mit Wechselstrom ähnliche Effekte zu erzielen.

   negative outer conductor; In the neutral conductor there is also a control resistor f which is used to regulate the temperature of the oxide. The current passes between the two outer conductors through the ionized vacuum.



   Although the use of direct current is primarily considered for this process, it is also possible to achieve similar effects with alternating current.

PATENT-ANSPRUCH : Verfahren zur Herstellung homogener Körper aus Tantalmetall oder anderen schwer schmelzbaren Metallen nach Patent Nr. 18611, bei dem der zu schmelzende Körper selbst als positive Elektrode dient, dadurch gekennzeichnet, dass in Verbindung mit der Kathode ein Metaltoxyd angeordnet ist, das beim Erhitzen Ionen aussendet, zu dem Zwecke, den Übergang des Stromes zwischen den Elektroden auch bei sehr hohem Vakuum zu er- leid) tern. EMI2.1 PATENT CLAIM: Process for the production of homogeneous bodies from tantalum metal or other metals that are difficult to melt according to Patent No. 18611, in which the body to be melted itself serves as a positive electrode, characterized in that a metal oxide is arranged in connection with the cathode which emits ions when heated, for the purpose of suffering the transition of the current between the electrodes even with a very high vacuum.
