Description

Verfahren zum Entlüften elektrischer Glühlampen. Zusatz zum Patent 339362. Den Gegenstand des Patentes 3o6634 bildet ein Verfahren zum Entlüften elektrischer Glühlampen und anderer Glasgefäße mittels eines in dem Innern der in ihm eingebauten Lampen kommunizierenden Behälter. Zur Verbindung der Lampen mit dem Behälter innen dienen kurze, an die Lampen oder Gefäße angesetzte Pumpröhrchen, deren freie Enden nach der Entlüftung innerhalb des Behälters zugeschmolzen werden. Dabei kann eine geringe Menge eines Glases von niedrigerem Schmelzpunkt als das Lampenglas an das zuzuschmelzende Ende des Pumpröhrchens gebracht werden, um den Schmelzvorgang zu erleichtern.Procedure for venting electric light bulbs. Addition to the patent 339362. The subject of patent 3o6634 is a method for venting electrical Incandescent lamps and other glass vessels by means of one in the interior of the built in it Lamps communicating container. To connect the lamps to the container inside serve short pump tubes attached to the lamps or vessels, their free ends be melted shut after venting inside the container. A small amount of a glass with a lower melting point than the lamp glass to the The end of the pump tube that is to be melted is brought to the melting process facilitate.

Nach dem Zusatzpatent 339362, kann der Verschluß auch so erfolgen, daß die Enden der Pumpröhrchen durch Erhitzen verflüssigt und in noch flüssigem Zustande aus der Heizzone entfernt werden.According to the additional patent 339362, the closure can also be carried out in such a way that the ends of the pump tubes are liquefied by heating and removed from the heating zone while they are still in the liquid state.

Gemäß der Erfindung wurde festgestellt, claß nicht nur leicht schmelzbares Glas mit Vorteil zur Beschleunigung und Sicherstellung des Verschlusses dienen kann, es können hierzu auch solche Stoffe verwendet werden, die mit dem Glas verschmelzen und dadurch ein leicht schmelzbares Glas ergeben. Solche Stoffe sind in erster Linie Alkalisalze und Bleioxyd. Das Aufbringen kann in jeder geeigneten Weise erfolgen, z. B. durch Aufstreichen in Form einer Paste oder durch Aufstreichen in Form trockenen Pulvers oder durch Aufbringen in Form einer Lösung, die hinterher getrocknet wird.According to the invention, it was found that not only easily meltable products Glass can advantageously serve to accelerate and secure the closure, substances that fuse with the glass can also be used for this purpose and thereby result in an easily meltable glass. Such substances are primarily Alkali salts and lead oxide. The application can be done in any suitable way, z. B. dry by spreading in the form of a paste or by spreading in the form Powder or by application in the form of a solution, which is then dried.
