DenGegenstanddesPatentes76896bildeteinVerfahrenzumEntlüftenelektrischerGlühlampen und anderer Glasgefässe mittels eines mit dem'Innern der in ihm eingebauten Lampen kommunizierenden Behälters. Zur Verbindung der Lampe mit dem Behälter innen dienen kurze, an die Lampen oder Gefässe angesetzte Pumpröhrchen. deren freie Enden nach der Entlüftung innerhalb des Behälters zugesehmolzen werden. Dabei kann eine geringe Menge eines Glases vpn niedrigerem Schmelzpunkt als das Lampenglas an das zuzuschmelzende Ende des Pnmpmhrchens gebracht werden, um den Schmelzvorgang zu erleichtern.
Nach dem Zusatzpatent Nr. 85952 kann der Verschluss auch so erfolgen, dass die Enden der Pump- röhrchen durch Erhitzen verflüssigt und in noch flüssigem Zustande aus der Heizzone entfernt werden.
Gemäss der Erfindung wurde festgestellt, dass nicht nur leichtschmelzbares Glas mit Vorteil zur
EMI1.1
verwendet werden, die mit dem Glas verschmelzen und dadurch ein leichtschmelzbares 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 getroeknet wird.

Method for venting electric light bulbs.
The subject of patent 76896 is a method for venting electric incandescent lamps and other glass vessels by means of a container that communicates with the interior of the lamps installed in it. Short pump tubes attached to the lamps or vessels serve to connect the lamp to the container inside. the free ends of which are bolted shut after venting inside the container. A small amount of a glass with a lower melting point than the lamp glass can be brought to the end of the tube to be melted in order to facilitate the melting process.
According to the additional patent no. 85952, the closure can also take place 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.
According to the invention, it was found that not only easily fusible glass is advantageous
EMI1.1
are used, which fuse with the glass and thereby result in an easily fusible glass. Such substances are primarily alkali salts and lead oxide. The application can be done in any suitable manner, e.g. B. by spreading in the form of a paste or by spreading in the form of dry powder or by applying in the form of a solution, which is then dried.
