 Hand anfassen kann, während der im Innern des Reflektors befindliche Teil der Entladungsröhre eine Temperatur von einigen Hundert Grad annehmen kann. 



   Wird der Metalldraht in Quarz oder anderes Hartglas eingeschmolzen, dann verfährt man zweckmässig so, dass über den z. B. aus Wolfram, bestehenden Draht ein ungefähr passendes   Quarzröhrchen   geschoben wird, wonach dieses Röhrchen entlüftet und sodann von der Mitte ausgehend erhitzt und gegebenenfalls auch gleichzeitig zusammengepresst wird. 



    PATENT-ANSPRACHE :  
1. Elektrische Entladungsröhre mit einem in Glas, insbesondere Quarz-, Borosilikatglas oder ähnliches   Hartglas, eingesehmolzenen Metalldraht, gekennzeichnet durch   ein den Metalldraht mit geringem Spiel   umschliessendes,   von der Entladungsröhre nach aussen vortretendes Kapillarröhrchen, in dessen äusseren Endteil der Metalldraht unmittelbar oder unter Vermittlung eines auf ihm aufgeschmolzenen Hartglasmantels eingeschmolzen ist.

 EMI2.1
 Hand while the part of the discharge tube located inside the reflector can reach a temperature of a few hundred degrees.



   If the metal wire is melted in quartz or other hard glass, then it is expedient to proceed so that the z. B. made of tungsten wire, an approximately matching quartz tube is pushed, after which this tube is vented and then heated from the center and possibly also pressed together at the same time.



    PATENT APPROACH:
1. Electrical discharge tube with a metal wire melted into glass, in particular quartz, borosilicate glass or similar hard glass, characterized by a capillary tube which surrounds the metal wire with little play and protrudes outward from the discharge tube, in the outer end part of which the metal wire is directly or through a is melted on it melted hard glass jacket.

Claims (1)

2. Entladungsröhre nach Anspruch 1, dadurch gekennzeichnet, dass das Kapillarröhrchen samt dem eingeschmolzenen Draht auf der Rückseite eines Reflektors angeordnet ist, der in seinem Innern die Entladungsröhre und gegebenenfalls auch noch wärmeerzeugende V orschaltwiderställde aufnimmt. 2. Discharge tube according to claim 1, characterized in that the capillary tube together with the melted wire is arranged on the back of a reflector which receives the discharge tube and possibly also heat-generating V orschaltwiderställde in its interior. 3. Verfahren zur Herstellung des den Draht umschliessenden Glasmantels, dadurch gekennzeichnet, dass der Draht mit Spiel in ein Rartglasröhrsshell eingeschoben, dieses darauf entlüftet und sodann von der Mitte ausgehend erhitzt und gegebenenfalls auch gleichzeitig zusammengepresst wird. EMI2.2 3. A method for producing the glass jacket enclosing the wire, characterized in that the wire is inserted with play into a rare glass tube shell, this is then vented and then heated starting from the center and optionally also pressed together at the same time.
