Description
<Desc/Clms Page number 1>
Gitter für elektrische Entladungsröhren und Verfahren zu deren Herstellung.
EMI1.1
<Desc/Clms Page number 2>
Elektrode aufzubringen, dass Beschädigung dieser Schicht nicht mehr möglich ist. Ausserdem bildet das Zirkoniumoxyd mit der metallenen Unterlage eine emailleartige Verbindung mit sehr günstigen Eigenschaften.
Die Erfindung wird an Hand der Zeichnung näher erläutert, in der ein Gitter einer elektrischen Entladungsröhre gemäss der Erfindung beispielsweise schematisch dargestellt ist.
In dieser Figur ist ein um die Stützen 2 und 3 gewickelter Gitterdraht 1 dargestellt, der aus einem Kern 4 besteht, der mit einer Zirkoniumoxydschicht 5 überzogen ist. Das Aufbringen dieser Schicht kann in der Weise erfolgen, dass, nachdem der Gitterdraht um die Stützen gewickelt worden ist, das Gitter mit Zirkoniumoxyd bespritzt wird oder dass z. B. das ganze Gitter in ein Bad eingetaucht wird, in dem sich dieses Oxyd in Suspension befindet. Es ist einleuchtend, dass die Erfindung nicht auf das beschriebene Ausführungsbeispiel beschränkt ist, sondern dass verschiedene andere Ausführungsformen möglich sind.
PATENT-ANSPRÜCHE :
1. Gitter für elektrische Entladungsröhren, dadurch gekennzeichnet, dass wenigstens auf einem Teil der Oberfläche dieses Gitters Zirkoniumoxyd vorhanden ist.

Grids for electric discharge tubes and processes for their manufacture.
EMI1.1
<Desc / Clms Page number 2>
To apply electrode that damage to this layer is no longer possible. In addition, the zirconium oxide forms an enamel-like connection with the metal base with very favorable properties.
The invention is explained in more detail with reference to the drawing, in which a grid of an electrical discharge tube according to the invention is shown schematically, for example.
In this figure, a grid wire 1 wound around the supports 2 and 3 is shown, which consists of a core 4 which is covered with a zirconium oxide layer 5. This layer can be applied in such a way that, after the grid wire has been wrapped around the supports, the grid is sprayed with zirconium oxide or that, for. B. the whole grid is immersed in a bath in which this oxide is in suspension. It is obvious that the invention is not restricted to the exemplary embodiment described, but that various other embodiments are possible.
PATENT CLAIMS:
1. Grid for electrical discharge tubes, characterized in that zirconium oxide is present on at least part of the surface of this grid.
