Description

In Hochspannungsröhren, z. B. zur Erzeugung von Röntgenstrahlen, oder in Hochspannungsgleichrichtern muß sorgfältig jede Spur von abgesplitterter Materie vermieden werden, da sie Anlaß zu unerwünschten Entladungen (Überschlägen) geben kann. Aus diesem Grunde sieht man gewöhnlich davon ab, Gasfangstoffe, sogenannte Getter, einzubringen, von denen sich leicht kleinste Teilchen ablösen können, sei es, daß sie in der Form von Verdampfungsgettern (Barium, Magnesium) angewendet werden oder als Adsorptionsgetter, wie Zirkon. Gemäß der Erfindung wird die Anwendung eines an sich sehr erwünschten Getters auch in Hochspannungsröhren dadurch ermöglicht, daß der gasaufnehmende Stoff in ein poröses Material eingeschlossen ist, durch welches zwar die Gase, jedoch "keine feste Substanz dringen können. Die Hülle soll also völlig undurchlässig für auch noch so kleine Kristalle sein, aber doch das molekulare oder atomare Gas diffundieren lassen, so daß das innen vorhandene Getter seine gasaufzehrende Wirkung ausüben kann.In high voltage tubes, e.g. B. to generate X-rays, or in high-voltage rectifiers must be carefully every trace of splintered matter be avoided as they give rise to undesired discharges (flashovers) can. For this reason one usually refrains from using gas traps, so-called Getters, from which the smallest particles can easily detach, should be introduced it is that they are used in the form of evaporation getters (barium, magnesium) or as an adsorption getter, such as zirconium. According to the invention, the application of a Getters, which are very desirable in themselves, are also made possible in high-voltage tubes, that the gas-absorbing substance is enclosed in a porous material through which the gases can penetrate, but no solid substance. So the shell should be completely impermeable to even the smallest crystals, but the molecular one or diffuse atomic gas, so that the getter present inside its gas-consuming Can have an effect.

Die Figuren zeigen in zum Teil schematischer Darstellung Ausführungsbeispiele der Erfindung. In Fig. i ist i die poröse metallische Wandung eines Röhrchens, das an denEnden fest zusammengequetscht ist. Es enthält im Innern den Getterstoff 2 und ist zudem an den beiden Enden mit Zuführungen 3 versehen. Das Röhrchen kann durch einen Strom aufgeheizt werden, falls das Getter ein bei Wärme besonders gut aufnehmender Stoff ist. Gemäß Fig. :z wird als Wandung ein Keramikröhrchen geeigneter Porosität benutzt, das an den Enden durch Kappen verschlossen ist. i ist wiederum die Wandung, 2 die Getterfüllung, q. sind Verschlußkappen, z. B. aus Metall, die eng anliegend auf die Keramikhülle aufgebracht werden.The figures show exemplary embodiments in a partially schematic representation the invention. In Fig. I i is the porous metallic wall of a tube which firmly squeezed together at the ends. Inside it contains the getter substance 2 and is also provided with feeders 3 at both ends. The tube can be heated by a current, if the getter is particularly good when it is warm absorbent substance. According to FIG.: Z, a ceramic tube is more suitable as a wall Used porosity, which is closed at the ends by caps. i is turn the wall, 2 the getter filling, q. are closure caps, e.g. B. made of metal, the be applied tightly to the ceramic shell.
