Description

Verfahren zur Herstellung von G:limmentladungsröhren zur Spannungsregelung Zusatz zum Patent 754 656 Das Patent 75q.656 betrifft eine Glimmentladungsrähre zur Gleichspannungsregelung, deren Kathode als die Innenwand des aus Isolierstoff bestehenden Entladungsgefäßes nahezu ganz überdeckender, elektrisch leitender Belag ausgebildet ist. Die Anode andererseits ist ebenfalls in Form eines elektrisch leitenden Belages auf einer Einstülpung des Entladungsgefäßes aufgebracht. Diese Beläge werden vorzugsweise durch Aufdampfen, Aufstäuben, Aufspritzen oder auf chemische Weise aufgebracht.Process for the production of glow discharge tubes for voltage regulation Addendum to patent 754 656 The patent 75q.656 relates to a glow discharge tube for direct voltage regulation, the cathode of which is designed as an electrically conductive coating that almost completely covers the inner wall of the discharge vessel made of insulating material. The anode, on the other hand, is also applied in the form of an electrically conductive coating on an indentation of the discharge vessel. These coverings are preferably applied by vapor deposition, dusting, spraying or by chemical means.

Die Erfindung hat sich zur Aufgabe gestellt, die fabrikatorische Herstellung derartiger Entladungsröhren möglichst zu vereinfachen; sie löst sie dadurch, daß diejenigen Teile, die nicht durch Elektroden bedeckt sein sollen, zunächst mit einer Schutzschicht versehen werden, dann die Elektrodenschicht auf die Wandung aufgebracht und schließlich die Schutzschicht aufgelöst wird.The invention has set itself the task of manufacturing production to simplify such discharge tubes as possible; it solves them in that those parts that should not be covered by electrodes, first with a Protective layer are provided, then the electrode layer is applied to the wall and finally the protective layer is dissolved.

Die erwähnte Schutzschicht wird an den gewünschten Stellen, z. B. zwischen den einzelnen Elektroden oder am Einschmelzrand des Kolbens aufgebracht. Als Material kann vorteilhaft Paraffin verwandt werden, weil es von wäßrigen Lösungen, die unter Umständen zur Herstellung der Elektrodenschi,chten benötigt werden, nicht benetzt wird, oder eine andere verhältnismäßig leicht zu verflüchtigende Substanz oder auch ein leicht zu entfernender Lack dienen. Es ist auch möglich, Schichten zu verwenden, die in flüssigem Zustand aufgetragen werden und sich später als Häutchen abziehen lassen, wie z. B. Kollodium oder Gelatine. Nach dem Aufbringen der Schutzhäutchen werden die Elektrodenbeläge nach dem im Hauptpatent beschriebenen Verfahren zweckmäßig in einem Arbeitsgang aufgebracht. Auf die abgedeckten Stellen wird zunächst keine Rücksicht genommen. Nach Herstellung der Elektrodenschichten werden die abgedeckten Stellen durch Entfernen der Schutzschicht freigelegt. Die Entfernung der Schutzschichten kann z. B. während des Pumpprozesses durch entsprechende Erwärmung und Abpumpen der vergasten Substanzen erfolgen. Es ist aber auch möglich, vor dem Pumpen die Schutzschichten durch entsprechende chemische Mittel abzulösen.The mentioned protective layer is applied in the desired places, e.g. B. applied between the individual electrodes or on the melted edge of the piston. Paraffin can advantageously be used as a material because it depends on aqueous solutions, which may be required to produce the electrode layers, are not is wetted, or another relatively easily volatilized substance or an easy one too serving to remove varnish. It is also possible, Use layers that are applied in the liquid state and later can be peeled off as a skin, such. B. collodion or gelatin. After applying the protective membrane, the electrode pads are described in the main patent Method expediently applied in one operation. On the covered places initially no consideration is given. After making the electrode layers the covered areas are exposed by removing the protective layer. the Removal of the protective layers can, for. B. during the pumping process by appropriate The gasified substances are heated and pumped out. But it is also possible Remove the protective layers using appropriate chemical agents before pumping.

Das vorgeschlagene Verfahren läßt sich nicht nur bei den eigentlichen Elektroden der Röhren nach dem Hauptpatent anwenden, sondern bei allen Teilen dieser Röhren, die bei der Herstellung mit einer leitenden Schicht überzogen werden sollen bzw: von einem Überzug frei gehalten werden sollen.The proposed method can be applied not only to the actual Apply electrodes to the tubes according to the main patent, but to all parts of this Tubes that are to be coated with a conductive layer during manufacture or: should be kept free from a coating.
