   Bei Entladungsröhren, die mit glühender Kathode und einer Dampffüllung arbeiten, kommt es darauf an, dass die Glaswände durch den Entladestrom gleichmässig erwärmt werden, damit der Dampf, dessen Spannung über dem durch die Aussentemperatur bestimmten   Säthgungsdruck   liegt, keine   Kondensssächen   findet. Solche   Kondensflächen   entstehen meist an den Stellen, an denen die Zuleitungsdrähte eingeschmolzen werden, da Verdickungen im Glas beim Einschmelzen unvermeidlich sind. Sie sind besonders störend

   Nach der vorliegenden Erfindung wird dieser Nachteil dadurch vermieden, dass die Zuleitungen zu den Elektroden an einer gemeinsamen   Etnschme ! zsteiie   eingeführt werden

   In the case of discharge tubes that work with a glowing cathode and a steam filling, it is important that the glass walls are heated evenly by the discharge current so that the steam, whose voltage is above the saturation pressure determined by the outside temperature, does not find any condensation surfaces. Such condensation surfaces usually arise at the points where the lead wires are melted, since thickening in the glass is unavoidable during melting. They are particularly annoying

 of the tubes do not allow.



   According to the present invention, this disadvantage is avoided in that the leads to the electrodes on a common Etnschme! partially introduced

Claims

is necessary to accommodate the body of the soil b, is of uniform thickness and has no thickening on the outside. As a result, their even heating is not disturbed- PATENT CLAIM: Discharge tube with a glowing cathode and an enclosed, steam-supplying body, characterized in that all of the supply wires to the electrodes are melted at a common point on the glass wall that is heated by the discharge current or by the cathode, for the purpose. To avoid Kondtusnaehea for the steam. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
