Patent-An Sprüche:Patent-to sayings: 4545 5555 ι. Bogenlichtelektrode mit Leuchtzusätzen von Molybdaten und Wolframaten, dadurch gekennzeichnet, daß sie als Leuchtzusätze die Molybdate oder Wolframate der seltenen Erden oder solche Stoffe enthält, die beim Brennen die Molybdate oder Wolframate der seltenen Erden bilden.ι. Arc light electrode with luminescent additives of molybdates and tungstates, characterized in that it contains the molybdates or tungstates of the rare earths or such substances as luminous additives, which when burning form the molybdates or tungstates of the rare earths. 2. Elektrode nach Anspruch 1, dadurch gekennzeichnet, daß gleichzeitig eine Eisenverbindung, z. B. wolframsaures Eisen, der Elektrode einverleibt wird, zu dem Zweck, die Lichtausbeute zu erhöhen.2. Electrode according to claim 1, characterized in that at the same time an iron compound, z. B. tungstate iron, the electrode is incorporated for the purpose of increasing the light output. 3. Elektrode nach Anspruch 1, dadurch gekennzeichnet, daß außer den Wolframaten der seltenen Erden noch Fluoride der Erdalkalien zugesetzt werden, zu dem Zweck, höhere Lichtausbeute, gleichmäßigere Verdampfung und ruhigeres Brennen zu erzielen.3. Electrode according to claim 1, characterized in that in addition to the tungstates fluorides of the alkaline earths are added to the rare earths for the purpose of to achieve higher light output, more even evaporation and calmer burning.
