Description

Verfahren zur Befestigung des Sockels auf dem Halse elektrischer Glühlampen Die jetzige Glühlampensockelung besteht meist darin, daß zunächst eine geeignete Harzlösung mit einem pulverförmigen Körper, wie Kreide oder Kalkspat, zu einem plastischen Kitt angeteigt, dann von diesem Kitt ein schmaler Streifen in den Sockelrand geschmiert, sodann der Sockel auf die Lampe gesetzt, die Lampe - Sockel nach oben -in den Trockenofen gebracht und hier durch Wärmezufuhr der Kitt getrocknet wird. Während des Trocknens verdunstet das Harzlösungsmittel. Das Harz selbst schmilzt auf dem Lampenhals und auf der inneren Metallfläche des Sockels etwas auf. Das jetzt bestehende Kalkspatharzgemisch bildet eine feste Masse, welche den Raum zwischen Sockelrand und Lampenhals vollkommen ausfüllt und somit eine feste Verbindung bzw. Kittung des Sockels mit der Glühlampe herbeiführt.Method of attaching the base to the neck of electric incandescent lamps The current incandescent lamp socket usually consists of first using a suitable one Resin solution with a powdery body, such as chalk or calcite, to a plastic one Putty made into a paste, then a narrow strip of this putty smeared into the base edge, then the base is placed on the lamp, the lamp - base upwards - in the drying oven brought and here the putty is dried by supplying heat. While drying the resin solvent evaporates. The resin itself melts on the lamp neck and on the inner metal surface of the base. The now existing calcareous resin mixture forms a solid mass, which completely eliminates the space between the edge of the base and the neck of the lamp fills and thus a firm connection or cementing of the base with the light bulb brings about.

Vorliegende Erfindung bezweckt, die Sokkelkittung zu vereinfachen, zu verbilligen und stabiler zu machen. Sie beruht darin, daß der oben resultierende Harzkalkspatring durch einen Ring aus einer festen Masse ersetzt wird. Dieser Ring, welcher nahezu den Raum zwischen Glas und innerem Sockelrand ausfüllen muß, wird mit einem Klebemittel versehen und die Kittung im Sockelofen vollzogen.The present invention aims to simplify the base cement, to make it cheaper and more stable. It is based on the above resulting Resin lime spar ring is replaced by a ring made of a solid mass. This ring, which almost has to fill the space between the glass and the inner edge of the base provided with an adhesive and the putty completed in the base oven.

Bei dem Verfahren wird I. das Harzlösungsmittel gespart, a. geht die Kittung schneller vor sich, da nur eine dünne Kittfläche abzubinden hat, 3. ist hervorzuheben die Gleichmäßigkeit des Kittmaterials, q.. die bedeutend größere Haltbarkeit des Kittringes und 5. Zeitersparnis durch Wegfall des Einrührens der Kittmasse.In the process I. the resin solvent is saved, a. goes the Putty is quicker in front of you, as only a thin putty surface has to be set, 3. is highlight the evenness of the cement material, q .. the significantly greater durability of the putty ring and 5. Time savings by eliminating the need to stir in the putty.

Das neue Verfahren wird beispielsweise in folgender Weise durchgeführt: Man nehme einen Aluminiumring, welcher den Raum zwischen innerem Sockelrand und Lampenhals nahezu ausfüllt. Die Form des Ringes an und für sich - er kann auch schraubenförmig sein - ist gleichgültig. Diesen Ring tauche man in geschmolzenen Schellack, lasse den Schellack am Ring erkalten, setze den Ring auf den Lampenhals, hierüber dann den-- Sockel und bringe die Lampe - Sockel nach oben - in den Trokkenofen, wo der Schellack in - kurzer Zeit schmilzt und nach dem Erkalten eine feste Sockelkittung erzeugt.The new procedure is carried out, for example, in the following way: Take an aluminum ring, which is the space between the inner edge of the base and Almost full neck of the lamp. The shape of the ring in and of itself - it can also be helical be - is indifferent. This ring is dipped in melted shellac, let cool the shellac on the ring, put the ring on the neck of the lamp, then over it the - base and bring the lamp - base up - into the drying oven, where the Shellac melts in a short time and a solid base cement after cooling generated.
