  Elektrische Lampe mit Widerstandsstift zwischen den Kohlenelektroden. 



   Gegenstand vorliegender Erfindung ist ein zwischen den Kohlenstiften elektrischer Lampen eingeschalteter Widerstandsstift, welcher die Stelle der bekannten Widerstandskerne vertreten soll, jedoch im Gegensatz zu diesen leicht ausgewechselt werden kann, um den wechselnden Bedingungen des Stromes zu entsprechen. 



     Die Widerstandsstifte sind   aus feuerfestem Material, wie feuerfestem Ton, liarborundum oder dgl. hergestellt, dem, damit der Stift teilweise auch ein Leiter der Elektrizität sei, genügend Graphit beigemischt wird ; auch kann dem Material ein die

     Hei   Bogenlampen, die nach der vorliegenden Erfindung mit einem Widerstandsstift versehen sind, bringt der Strom   den Widerstandsstift   zur Glut und bewirkt durch die so erzeugteHitzegewissechemischeBeaktionen. 



   Eine dieser Reaktionen besteht darin. dass z.   H.   das in den Kohlen enthaltene

 bietet dem Strom einen neuen Weg und so wird   der Bogen zwischen den Kohlen rings   um den Widerstandsstift   gebildet.   



   Die Zeichnung zeigt in Fig. 1 den   Widerstandsstift zwischen   den beiden Kohlenstiften liegend, und in Fig. 2 allein. Die Kohlenstifte A sind mit einer zentralen Bohrung B versehen, in welche die   konischen   Spitzen des Widerstandsstiftes C eintreten, so, dass   letzterer sicher festgehalten wird. Der   in Fig. 2 dargestellte Widerstandsstift ist   länger

 standsstift in gleicher   Weis''wie die bekannten   Widerstandskerne wirkt, jedoch mit dem   Unterschied, dass   der Stift, trotzdem er   weissglühend   wird, nicht abbrennt, sondern einen annähernd konstanten Abstand zwischen den   Kohlenenden   aufrecht   erhalt.

   Durch Ver-     änderung der Läug   oder des Widerstandes dieser Stifte kann auch die Qualität und Stärke des zwischen den Kohlenstiften erzeugten Lichtes geändert werden: selbstverständlich müssen aber auch korrespondierende Änderungen des   Stroll1zulaufes     vorgenommen   werden, um   das beste Resultat   zu sichern.

  Electric lamp with resistance pin between the carbon electrodes.



   The subject of the present invention is a resistor pin connected between the carbon pins of electric lamps, which is intended to take the place of the known resistor cores, but in contrast to these can easily be exchanged in order to correspond to the changing conditions of the current.



     The resistance pins are made of refractory material, such as refractory clay, liarborundum or the like. Manufactured to which enough graphite is added so that the pin is also partially a conductor of electricity; the material can also be a die
 EMI1.1
 



     In arc lamps which are provided with a resistance pin according to the present invention, the current brings the resistance pin to glow and causes certain chemical reactions as a result of the heat thus generated.



   One of those reactions is. that z. H. that contained in the coals
 EMI1.2
 offers a new path for the current and so the arc is formed between the coals around the resistance pin.



   The drawing shows in Fig. 1 the resistance pin lying between the two carbon pins, and in Fig. 2 alone. The carbon pins A are provided with a central hole B, into which the conical tips of the resistance pin C enter, so that the latter is securely held. The resistor pin shown in Fig. 2 is longer
 EMI1.3
 The stand pin works in the same way as the well-known resistor cores, but with the difference that the pin, despite the fact that it becomes incandescent, does not burn off, but maintains an approximately constant distance between the coal ends.

   By changing the length or resistance of these pins, the quality and strength of the light generated between the carbon pins can also be changed: of course, corresponding changes to the stroll feed must also be made to ensure the best result. When the resistance is proportioned accordingly.
 EMI1.4
   remain.



   PATENT CLAIMS:
 EMI1.5
 Pen made of conductive and non-conductive, refractory materials with or without the addition of salts with high light emission, characterized in that the resistance pin C is a loosely between the ends of the carbon pin! e Jt arranged and supported between the carbon pin ends in a journal-like manner.
