Description

Gegenstand des Patents 754 656 ist eine Glimmentladungsröhre zur Gleichspannungsregelung, deren Kathode als ein die Innenwand des aus Isolierstoff bestehenden Entladungsgefäßes nahezu ganz überdeckender, elektrisch leibender Belag ausgebildet ist und das eine Einstülpun:g 'hat, auf der die Anode ebenfalls in Form eines elektrisch leitenden Belages aufgebracht ist. Diese Beläge werden vorzugsweise durch Aufdämpfen, Aufstäuben, Aufspritzen oder auf chemische Weise aufgebracht.The subject of patent 754 656 is a glow discharge tube for direct voltage regulation, its cathode as an inner wall of the discharge vessel made of insulating material almost completely covering, electrically living covering is formed and one Einülpun: g 'has on which the anode is also in the form of an electrically conductive one Covering is applied. These coverings are preferably applied by steaming, dusting, Spray on or applied chemically.

Verschiedene: der zur Herstellung des Belages geeigneten Materialien, z. B. :das auch im Hauptpatent erwähnte kolloidale Graphit, besitzen im Verhältnis zu reinen Metallen einen großen Kathodenfall. Sind Metallbeile vorhanden, die über die Oberfläche dieser Schicht hervorragen und mit ihm in leitender Verbindung stehen, so zieht sich aus diesem Grund die Entladung am Metall zusammen: Es treten dann örtliche Erwärmungen auf, die so groß sein können, daß der Kolben an dieser Stelle beschädigt wird, ja sogar schmilzt.Various: the materials suitable for the production of the covering, z. B.: The colloidal graphite also mentioned in the main patent, have a ratio to pure metals a large cathode fall. Are there metal hatchets that over the surface of this layer protrudes and is in conductive connection with it, so for this reason the discharge on the metal contracts: it then occurs local heating, which can be so great that the piston at this point is damaged, even melts.

Auf Grund dieser Feststellungen schlägt die Erfindung vor, bei Röhren nach dem Patent 754 656 die Zuführung, insbesondere die Kathodenzuführung, zu dem leitenden Belag so anzubringen, daß dieselbe durch den Belag abgedeckt wird, d. b. innerhalb oder unterhalb des leitenden Belages liegt.On the basis of these findings, the invention proposes for tubes according to the patent 754 656 the feed, in particular the cathode feed, to the to apply conductive covering so that it is covered by the covering, d. b. lies within or below the conductive covering.

In der Zeichnung ist eine beispielsweise Ausführungsform der Erfindung dargestellt. Die Wandung des Glaskolbens i ist nach innen gezogen, so daß zwei koaxiale Zylinder zueinander entstehen. Auf dem inneren und auf dem äußeren zylindrischen Teil ist je eine leitende Belegung 3 und 4 aufgebracht, z. B. aus kolloidalem Graphit. Die beiden leitenden Belegungen stehen miteinander nicht in Berührung-, sondern bilden die beiden Elektroden der Glimmentladungsstrecke. Der innere Raum des Glasgefäßes .ist mit einem geeigneten Gas gefüllt. Die Zuführungen 5 zu den leitenden Belägen sind, wie aus der Abbildung ersichtlich, so eingeschmolzen, daß der Zuführungsdraht unterhalb der leitenden Belegung liegt bzw. kann er etwas innerhalb liegen. Es ist jedoch oft notwendig, um die Glimmentladung :gleichmäßig zu verteilen, dafür zu sorgen, daß an der Zuführungsstelle der Abstand zwischen den beiden Elektroden derselbe ist wie an den übrigen Stellen. Wie oben schon angedeutet, ist diese Art der Zuführung notwendig im Hinblick auf den großen Kathodenfall gewisser Materialien. Es ist auch öfter zweckmäßig, an der Durchführungsstelle, z. B. dann, wenn es sich um ein Gefäß aus keramischem :Material bandelt, eine Einkerbung vorzusehen, in welche der Zuführungsdraht eingelegt wird, so daß im Innern die Wandung der Elektrode nicht verdickt wird.In the drawing is an exemplary embodiment of the invention shown. The wall of the glass bulb i is drawn inwards, so that two coaxial Cylinders to each other arise. On the inner and on the outer cylindrical Part is each a conductive assignment 3 and 4 applied, z. B. from colloidal graphite. The two conductive assignments are not in contact with one another, but rather form the two electrodes of the glow discharge path. The inner space of the glass vessel .is filled with a suitable gas. The leads 5 to the conductive coverings are, as can be seen from the figure, fused in such a way that the feed wire lies below the conductive occupancy or can be somewhat within. It is however often necessary to the glow discharge: to distribute it evenly, for it too ensure that the distance between the two electrodes is the same at the feed point is like in the other places. As already indicated above, this is the type of feed necessary in view of the large cathode drop of certain materials. It is also more often appropriate, at the implementation point, z. B. if it is a vessel made of ceramic: material tapes to provide a notch into which the lead wire is inserted so that the wall of the electrode is not thickened inside.
