KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. PATENTSCHRIFTPATENT LETTERING - M 238758 KLASSE 21/. GRUPPE 39.- M 238758 CLASS 21 /. GROUP 39. LICHTWERKE G. m. b. H. i. K. in BERLIN.LICHTWERKE G. m. B. Hi. K. in BERLIN. Verfahren zum Einschmelzen der Zuleitungsdrähte elektrischer Glühlampen in den Lampenfuß in indifferenter Atmosphäre.Method for melting down the lead wires of electric incandescent lamps in the lamp base in an indifferent atmosphere. Patentiert im Deutschen Reiche vom 7. April 1910 ab.Patented in the German Empire on April 7, 1910. Gegenüber denjenigen Verfahren, nach denen der Zuleitungsdraht für die Glühfäden elektrischer Glühlampen mit einem Glasüberzug versehen ist, der den Draht vor der Flamme und ihren Verbrennungsprodukten schützen soll und bei welchen Verfahren das Einschmelzen auch im Vakuum oder in indifferenten Gasen vorgenommen wird, besteht der Gegenstand der vorliegenden ErfindungCompared to those methods according to which the lead wire for the filaments electric incandescent lamps are provided with a glass coating that holds the wire in front of the Flame and its combustion products and with which processes this Melting is also carried out in a vacuum or in inert gases the subject of the present invention ίο darin, daß man das Glas und die Drähte beim Einschmelzen nur durch strahlende Wärme erhitzt. Dies geschieht zweckmäßig durch elektrische Heizspulen. Um die Wirkung des Sauerstoffes auszuschließen, wird im Stickstoffstrom oder im Vakuum gearbeitet, wie dies bisher auch schon bei anderen Einschmelzverfahren ausgeübt wurde.ίο in having the glass and the wires at Melting is only heated by radiant heat. This is done expediently through electric heating coils. In order to exclude the effect of the oxygen, is in the nitrogen flow or worked in a vacuum, as has already been done with other melting processes was exercised. Werden die Drähte in der vorerwähnten Weise eingeschmolzen, so wird den Verletzungen der Glühlampenbirnen erheblich vorgebeugt, und die etwas verteuerte Arbeit wird durch die Vermeidung von Ausschuß und Bruch mehrfach ausgeglichen.If the wires are melted down in the aforementioned manner, injuries will result the incandescent lightbulbs prevented considerably, and the somewhat more expensive work is made by avoiding rejects and Break evened out several times. PATENT-AnSI3EUCH:PATENT-ANSI 3 YOU: Verfahren zum Einschmelzen der Zuleitungsdrähte elektrischer Glühlampen in den Lampenfuß in indifferenter Atmosphäre, dadurch gekennzeichnet, daß man das Glas und die Drähte beim Einschmelzen nur durch strahlende Wärme erhitzt.Method for melting the lead wires of electric incandescent lamps in the lamp base in an indifferent atmosphere, characterized in that the glass and the wires are melted down heated only by radiant heat.
