 angeschlossen. Das   Gefäss-5-ist   in einem   Thermostat --6-- untergebracht,   dessen Temperatur zweckmässig auf 70 bis 90 C eingestellt ist. Der Thermostat sichert bei dieser Temperatur die erforderliche Höhe des Dampfdruckes. 



   Jener Teil des Leitungssystems-3-, welcher sich zwischen dem   Gefäss-5-und   der   Lampe --2-- befindet,   wird erwähnt, so dass das   System --3-- samt   den   Ventilen-7, 8- eine   Temperatur aufweist, die nicht wesentlich niedriger liegt, als jene der   Lampe-2-und   des Gefässes --5--. Damit die   Lampe-2-auf   der erforderlichen Temperatur gehalten werden kann, ist ein 
 EMI2.1 
 



   Nach diesen Vorbereitungen wird durch öffnen des Ventils --7-- des Jodgefässes --5-- und gleichzeitigem Sperren des   Vendles-8-das System-3-und   die Lampe-2-mit Joddampf gleichmässig gefüllt. Das   Ventil --7-- wird   ein bis zwei Sekunden lang offen gelassen und danach gesperrt, worauf mittels eines andern, in der Zeichnung nicht dargestellten Ventiles in die Lampe   - 2-ein Füllgas, z. B.   Argon, eingeführt wird. Der Druck dieses Füllgases beträgt das Mehrfache des Druckes des Halogens, so dass sein Einströmen gesichert ist. Durch die erwähnte Temperatur des 
 EMI2.2 
 Halogengemisch verwendet wird, ist selbstverständlich die Temperatur des Systems entsprechend dem erwünschten Druck einzuregeln. 



   Hierauf wird der Quarzkörper der   Lampe --2-- mittels   eines Gasbrenners abgeschmolzen. 



  Während des ersten Brennens der Lampe werden die eingeführten Metalle mittels einer Stromquelle von hoher Spannung und Frequenz unter der Wirkung der Entladung mit dem anwesenden Halogen in Salz umgewandelt. 



   Eine so hergestellte, Metallhaloide enthaltende Entladungsröhre, kann bereits mit dem üblichen Zünder (Starter) angelassen bzw. in Betrieb gesetzt werden.

 connected. The vessel-5- is housed in a thermostat --6--, the temperature of which is conveniently set to 70 to 90 C. The thermostat ensures the required level of steam pressure at this temperature.



   That part of the line system-3- which is between the vessel-5- and the lamp -2- is mentioned, so that the system -3- together with the valves -7, 8- has a temperature which is not significantly lower than that of the lamp 2 and the vessel 5. So that the lamp-2-can be kept at the required temperature is a
 EMI2.1
 



   After these preparations, the system-3-and the lamp-2-are evenly filled with iodine vapor by opening the valve --7-- of the iodine vessel --5-- and at the same time blocking the vendles-8. The valve --7-- is left open for one to two seconds and then locked, whereupon by means of another valve, not shown in the drawing, into the lamp - 2-a filling gas, e.g. B. argon is introduced. The pressure of this filling gas is a multiple of the pressure of the halogen, so that its inflow is ensured. Due to the mentioned temperature of the
 EMI2.2
 Halogen mixture is used, the temperature of the system is of course to be regulated according to the desired pressure.



   The quartz body of the lamp --2-- is then melted using a gas burner.



  During the first lighting of the lamp, the introduced metals are converted into salt by means of a power source of high voltage and frequency under the effect of the discharge with the halogen present.



   A discharge tube produced in this way and containing metal halides can already be started or put into operation with the usual igniter (starter).

Claims (1)

PATENTANSPRUCH : Verfahren zur Herstellung von gasgefüllten elektrischen Entladungsröhren mit Metallhaloidzusatz, EMI2.3 Entladungsröhre in elementarer Form zugesetzt wird und danach das zur Bildung von Metallhaloid erforderliche Halogen oder Halogengemisch, sowie der erforderliche Halogenüberschuss in elementarer Form mittels Verdampfen in die Entladungsröhre eingeführt wird, wodurch die Metallhaloide in der Entladungsröhre selbst gebildet werden. PATENT CLAIM: Process for the production of gas-filled electric discharge tubes with addition of metal halides, EMI2.3 Discharge tube is added in elemental form and then the halogen or halogen mixture required for the formation of metal halide, as well as the required halogen excess is introduced in elemental form by means of evaporation into the discharge tube, whereby the metal haloids are formed in the discharge tube itself.
