  ElektrischeGaslampe. 



   Durch das   Stammpatent Nr. 71448   ist eine elektrische Gaslampe unter Schutz gestellt, die   dadurch gekennzeichnet ist, dass in   der Leuchtröhre geringe Mengen eines oder mehrerer Alkali- 
 EMI1.1 
 enthalten sind, wogegen die Elektroden aus irgend einem   geeigneten Leicht-oder Schwermetall   bestehen können, zu dem Zwecke, die Lampe auch bei niedrigem Potentialgefälle ohne An-   wendung der Alkalimetalle   als Elektrodenmaterial betreiben zu können. 



   Es hat sich nun gezeigt, dass die   Leuchtröhre   als solche von den   erwähnten   geringen Mengen   oder   mehrerer Alkalimetalle freigelassen werden kann und diese nur im Bereiche der Elektroden angeordnet werden können, um die gleiche Wirkung herYorzuhringen und dass es   sogar genügt, diese geringen Mengen der Alkalimetalle   im Bereiche der   Anod allein unter-   zubringen. 



   Bei Gaslampen mit Alkalimetall-Elektroden hat man die Erfahrung gemacht, dass wenigstens die Kathode aus einem Alkalimetall oder einer Legierung von Alkalimetallen be-   stehen muss. Abgesehen   davon, dass   gemäss   der vorliegenden Erfindung die Elektroden aus irgend

  Electric gas lamp.



   An electric gas lamp is protected by the master patent No. 71448, which is characterized in that small amounts of one or more alkali
 EMI1.1
 are included, whereas the electrodes can consist of any suitable light or heavy metal, for the purpose of being able to operate the lamp even with a low potential gradient without using the alkali metals as electrode material.



   It has now been shown that the fluorescent tube as such can be released from the mentioned small amounts or more alkali metals and these can only be arranged in the area of the electrodes in order to produce the same effect and that it is even sufficient to use these small amounts of alkali metals in the To accommodate areas of the anod alone.



   In gas lamps with alkali metal electrodes, experience has shown that at least the cathode must consist of an alkali metal or an alloy of alkali metals. Apart from the fact that, according to the present invention, the electrodes consist of any
