Description

Lumineszierende Gasröhre Es sind bereits zwei Verfahren zum Erzeugen lumineszierender Entladungsröhren bekannt, nämlich einmal durch Herstellten von Glasröhren, deren Wandung vollständig oder zum Teil aus einem lumineszierenden Glas besteht, und außerdem durch Aufbringen pulverförmiger kristallisierter Leuchtstoffe auf die Innenwand gewöhnlicher Glasrohre. Beide Verfahren haben technische Nachteile. Die Verwendung lumineszierender Gläser als Glasröhren wird z. B. dadurch erschwert, daß gerade die am besten lumineszierenden Gläser sich oft glastechnisch sehr ungünstig verhalten und schlecht verarbeiten lassen.Luminescent Gas Tube There are already two methods of creating it luminescent discharge tubes known, namely once by producing Glass tubes, the walls of which are completely or partially made of luminescent glass consists, and also by applying powdery crystallized phosphors on the inner wall of ordinary glass tubes. Both methods have technical disadvantages. The use of luminescent glasses as glass tubes is z. B. made more difficult that precisely the best luminescent glasses are often very unfavorable in terms of glass technology restrained and badly processed.

Das vorliegende Verfahren verwendet deshalb die Lumineszenzgläser nicht als Glasröhren selbst, sondern nach ihm werden diese Gläser zu Fasern oder Fäden verarbeitet und eine Schicht dieser Glasfäden oder Fasern an der Innenseite von Glasröhren beliebiger Zusammensetzung zum Anliegen gebracht. Auch Gläser, die sich zur Verarbeitung von Glasröhren schlecht oder gar nicht eignen, lassen sich zu Glasfäden oder Fasern sehr gut verarbeiten. Aus diesem Grunde erlaubt das vorliegende Verfahren die Benutzung einer großen Anzahl von bisher technisch nicht brauchbaren Lumineszenxgläsern: Auch ,an die hydrolytische Widerstandsfähigkeit des Glases für die Fäden oder Fasern. braucht, da sie sich nach Verarbeitung zu einer Entladungsröhre in deren Innerem befinden, keine besonderen Ansprüche gestellt zu werden.The present method therefore uses the luminescent glasses not as glass tubes themselves, but after him these glasses become fibers or Threads processed and a layer of these glass threads or fibers on the inside brought to concern by glass tubes of any composition. Even glasses that are poorly or not at all suitable for processing glass tubes, can be can be processed very well into glass threads or fibers. Because of this, the present Process the use of a large number of previously not technically useful Lumineszenx glasses: Also, of the hydrolytic resistance of the glass for the threads or fibers. needs, as it turns into a discharge tube after processing inside are not to be made any special claims.

Ein weiterer Vorteil des neuen Verfahrens ist darin zu sehen, daß es gestattet, auf einfache Weise verschieden lumineszierende Gläser gleichzeitig zur Wirkung zu bringen. Man braucht dazu nur entweder die Glasfaserschicht durch Mischen von Einzelfäden aus verschiedenem Lumineszenzglas herzustellen oder mehrere Glasfasernschichten im Innern des Glasrohres übereinander anzubringen.- fs ist selbstverständlich, daß das die eigentliche Hülle bildende Glasrohr beliebig gefärbt tte unter Umständen auch selbst Lumineszenzfähig, sein kann.Another advantage of the new method can be seen in the fact that it allows different luminescent glasses to be produced at the same time in a simple manner to bring to effect. Man only needs either the fiberglass layer by mixing single threads from different luminescent glass or to attach several layers of fiberglass inside the glass tube on top of each other. It goes without saying that the glass tube forming the actual envelope is arbitrary colored tte may also be capable of luminescence itself under certain circumstances.

Glasröhren nach der Erfindung lassen sich in einfacher Weise z. B. dadurch herstellen, daß man ein ein oder mehrere Millimeter dickes Glasfaservließ um einen Glasstab von geringerem Durchmesser als die lichte Weite des Glasrohres wickelt, das Ganze in das Glasrohr einführt und das Glasfaservließ mit Hilfe des Stabes an die äußere Wandung anpreßt. Durch Herausziehen dieses Stabes entsteht der Hohlraum, in dem sich die Gasentladung bei der Verarbeitung zu einer Entladungsrötere ausbilden kann. War die Innenfläche des Rohres vor dem Einbringen des Vließes in bekannter Weise mit einem '13i. demittel, z. B. Wasserglas oder sirupöser P.h:sphorsäure, in dünner Schicht überzogen, wird auf diese Weise eine besonders gute @HaftunL, des Vließes an der Glaswand erzielt:Glass tubes according to the invention can be easily z. B. manufacture by a one or several millimeters thick glass fiber fleece around a glass rod with a smaller diameter than the clear width of the glass tube wraps, introduces the whole thing into the glass tube and the glass fiber fleece with the help of the Rod pressed against the outer wall. Pulling out this rod creates the cavity in which the gas discharge becomes red when it is processed can train. Was the inner surface of the pipe before the fleece was placed in known way with a '13i. demittel, z. B. water glass or syrupy P.h: phosphoric acid, Covered in a thin layer, a particularly good @HaftunL, of the fleece on the glass wall achieved:
