Bemerkt sei, dass es bekannt ist, in Glüillampen, deren Glühfäden aus Vanadium, Titan oder einen anderem sich mit Stickstoff unmittelbar verbindenden Metall oder Metalloid besteht, nach dem Auspumpen Luft von einem ungefähren Druck von 3 mm Hg zu bringen und hieraus den Stickstoff und Sauerstoff durch Glühen des Fadens zu beseitigen, so dass eine Atmosphäre von Argon und anderen Edelgasen zurückbleibt, deren Druck etwa 0#03 mm Hg beträgt.
Ferner ist bekannt, Osmiumglühlampen mit Stickstoff-Sauerstoffgemischen. mit einem

Bei der vorliegenden Erfindung handelt es sich jedoch um eine Gasfüllung von anderer Zusammensetzung und viel höheren Druck, wobei der darin enthaltene Stickstoff einem anderen Zwecke dient.

require much higher voltage.
It should be noted that it is known, after pumping out, to bring air at an approximate pressure of 3 mm Hg into incandescent lamps, the filaments of which are made of vanadium, titanium or another metal or metalloid that connects directly to nitrogen, and from this the nitrogen and oxygen by annealing the filament, leaving an atmosphere of argon and other noble gases, the pressure of which is about 0.03 mm Hg.
It is also known to use osmium incandescent lamps with nitrogen-oxygen mixtures. with a

The present invention, however, is a gas filling of a different composition and much higher pressure, with the nitrogen contained therein serving a different purpose.
