Verfahren zur Entgasung von Elektronenröhren mittels Metallzerstäubung im
Wirbelstromofen.

<Desc/Clms Page number 2>
Abhilfe gegen diese Unregelmässigkeit wird laut vorliegender Erfindung (s. Fig. 2) dadurch geschaffen, dass der Anodenzylinder mit einem faazartigen Schlitz F versehen ist, in den das zu zerstäubende Metall P wie in eine Tasche eingeschoben wird ; Ein Herunterfallen des Materiales bei teilweiser Ver- dampfung ist dadurch unmöglich gemacht, denn dabei kann die abgemessene Metallmenge nur neuerlich an anderen Punkten mit der Anodenoberfläche in Berührung treten, bis sie vollständig zerstäubt ist.
Zweckmässigerweise kann dieser Schlitz im Anodenzylinder dadurch hergestellt werden, dass dieser Zylinder aus einem Blechstreifen so zusammengerollt wird, dass sich die Enden überlappen. Besonders einfach ist es, diesen Zylinder an den Enden der Überlappung durch Punktschweissung zusammenzuheften, hierauf in die Mitte des Schlitzes das Zerstäubungsmetall einzuführen und auch dieses durch
Schweissung im Innern dieser Tasche zu befestigen, wodurch ein besonders sicherer Wärmekontakt entsteht.

This irregularity is remedied according to the present invention (see FIG. 2) in that the anode cylinder is provided with a façade-like slot F, into which the metal P to be atomized is inserted like a pocket; This makes it impossible for the material to fall down during partial evaporation, because the measured amount of metal can only come into contact with the anode surface again at other points until it is completely atomized.
This slot can expediently be produced in the anode cylinder in that this cylinder is rolled up from a sheet metal strip in such a way that the ends overlap. It is particularly easy to tack this cylinder together at the ends of the overlap by spot welding, then to insert the atomizing metal into the center of the slot and then through this too
To fix welding inside this pocket, which creates a particularly safe thermal contact.

contact is wedged in a fold of the anode cylinder.
