Description

Störungslose Inbetriebnahme elektrischer Bogenlampen Gegenstand der Erfindung ist ein Verfahren zur sofortigen störungslosen Inbetriebnahme von elektrischen Bogenlampen, z. B. für Kinovorführungen, sowie hierfür geeignete Betriebsmittel.Trouble-free commissioning of electric arc lamps is the subject of The invention is a method for immediate, trouble-free start-up of electrical Arc lamps, e.g. B. for cinema screenings, as well as suitable equipment.

Die übliche Methode zum Anzünden eines Lichtbogens in einem Kinoprojektionsapparat war bisher diejenige, die negative Elektrode des Lichtbogens in Berührung mit der positiven Elektrode zu bringen, den Strom einzuschalten und hierauf die negative Elektrode wieder abzuziehen, um eine kleine Spalte zu schaffen zwecks Entzündung des Bogens, worauf die Entfernung der Elektrode eingestellt wird, um das gewünschte Maximum von Helligkeit des Bogens zu erzielen.The most common method of lighting an arc in a cinema projector was previously the one that made contact with the negative electrode of the arc to bring the positive electrode, to switch on the current and then the negative Remove the electrode again to create a small gap for inflammation of the arc, after which the distance of the electrode is adjusted to the desired To achieve maximum of brightness of the arch.

Zweck der vorliegenden Erfindung ist die Elir,inierung der Notwendigkeit dieser Arbeitsweise zum Entzünden und Einstellen des Bogens von Hand. Dies wird erfindungsgemäß dadurch erreicht, daß die Elektroden durch Zwischenschaltung geeignet geformter, elektrisch leitender, leicht zerstörbarer, z. B. verbrennbarer oder schmelzbarer Formstücke beim Zünden in der für den Dauerbetrieb erforderlichen Entfernung gehalten werden. Ein derartiges Kügelchen ist also zwischen die Lichtbogenelektroden geklemmt und distanziert sie hierdurch auf ihren normalen Arbeitsabstand.The purpose of the present invention is to elicit the need this way of working to ignite and adjust the arc by hand. this will achieved according to the invention in that the electrodes are suitable by interposing them shaped, electrically conductive, easily destructible, e.g. B. combustible or fusible Fittings held at the distance required for continuous operation when igniting will. Such a bead is thus clamped between the arc electrodes and thereby distances them to their normal working distance.
