  Verfahren zum Ausscheiden der in den Fadenträgern elektrischer   Glühlampen   enthaltenen Gase. 



   Es ist bekannte Tatsache, dass fast sämtliche Metalle,   wom   sie in Wasserstoff oder in anderen Gasen erhitzt worden sind, eine gewisse Menge dieser Gase in sich zurückbehalten. Die metallischen Fäden elektrischer Glühlampen zeigen das gleiche Verhalten, wenn sie z. B. in Wasserstoff oder in einem wasserstoffhaltigen Gasgemisch erhitzt werden. Um das im Faden der Glühlampe enthaltene Gas auszuscheiden, wird bekanntlich dieser Faden beim Leeren der Birne durch Hindurchleiten eines elektrischen Stromes glühend gemacht. Wenn der Faden aber mit demselben Träger in die Glasbirne eingeführt wird, auf welchem er bei seiner Bildung in einem zur Rotglut erwärmten Gas, z. B.

   Wasserstoff, erhitzt worden ist, genügt das Durchleiten eines elektrischen Stromes nicht, um während der Leerung der Birne das Gas auszuscheiden, denn die durch diesen Strom verursachte Erhitzung des Fadens vermag das in den metallischen Bestandteilen (Haken, Stange, Masse, mittels welcher der Faden an die Haken befestigt ist usw.) enthaltende Gas nicht zu vertreiben. Dieser Umstand erschwert die Leerung der Birnen bedeutend, da das in diesen metallischen Bestandteilen enthaltene Gas sehr langsam aus denselben heraustritt. 



  Wenn aber auch nur Spuren von solchen Gasen und besonders von Wasserstoff in der Glasbirne zurückbleiben, so ist dies von nachteiligen Einfluss auf dio Brenndauc. der Lampe. 



   Die Erfindung besteht darin, dass die Fädun mit ihren Trägern, bevor man   sie in   die Birne einsetzt, in einem indifferenten Gase, das vom Metall so gut wie nicht zurückgehalten wird (beispielsweise Stickstoff), durch eine äussere, vom Faden   unabhängige Wärme-     quelle erhitzt   werden. 



   Das im Metall enthaltene Gas, vorzugsweise Wasserstoff, entweicht sehr rasch und beinahe vollständig. Diese Entweichung geht um so rascher vor sich und wird um so vollständiger, je höher die Temperatur ist, bis zu welcher der Träger erhitzt wird.

  Process for eliminating the gases contained in the filament of electric light bulbs.



   It is a known fact that almost all metals that have been heated in hydrogen or other gases retain some amount of these gases. The metallic filaments of electric incandescent lamps show the same behavior when they e.g. B. be heated in hydrogen or in a hydrogen-containing gas mixture. In order to eliminate the gas contained in the filament of the incandescent lamp, this filament is known to be made glowing when the bulb is emptied by passing an electric current through it. But if the thread is inserted into the glass bulb with the same carrier on which it was formed in a gas heated to red heat, e.g. B.

   Hydrogen, has been heated, the passage of an electric current is not enough to excrete the gas while the pear is being emptied, because the heating of the thread caused by this current can do that in the metallic components (hook, rod, mass, by means of which the thread attached to the hook, etc.) containing gas. This circumstance makes emptying the pears very difficult, since the gas contained in these metallic components escapes from them very slowly.



  But if only traces of such gases, and especially of hydrogen, remain in the glass bulb, this has a detrimental effect on the burning time. the lamp.



   The invention consists in the fact that the thread with its carrier, before being inserted into the pear, is heated by an external heat source that is independent of the thread in an inert gas that is hardly retained by the metal (e.g. nitrogen) will.



   The gas contained in the metal, preferably hydrogen, escapes very quickly and almost completely. This escape takes place all the more rapidly and becomes all the more complete the higher the temperature up to which the support is heated.
