Die im Hauptpatent beschriebene Erfindung beruht auf dem Gedanken, zwei Dichtungsarten in Gemeinschaft zu verwenden, nämlich die an sich bekannte und für Vakiiumgefäße unentbehrliche Quecksilberdichtung in Verbindung mit den an sich ebenfalls bekannten Dichtungen, wie sie beim Aufeinanderpassen von Maschinenteilen u. dgl. verwandt werden, also z. B. Asbest.The invention described in the main patent is based on the idea of using two types of seal in common, namely the mercury seal, which is known per se and is indispensable for vacium vessels with the seals, which are also known per se, as they fit together of machine parts and the like. B. Asbestos.
Es hat sich nun gezeigt, daß es sehr schwer ist, aus derartigen Dichtungen die sogenannten Restgase herauszubringen. Asbest, Glaswolle o. dgl. Dichtungsmittel bergen in ihren festen Teilen Luft und Feuchtigkeit, während Gummi und dessen äquivalente Dichtungsmittel noch kleine organische und anorganische Rückstände enthalten, welche geeignet sind, das Vakuum zu verunreinigen.It has now been shown that it is very difficult to make the so-called Bring out residual gases. Asbestos, glass wool or the like. Sealants are contained in their solid Share air and moisture, while rubber and its equivalent sealant still do Contain small organic and inorganic residues, which are suitable for the vacuum to contaminate.
Der Erfindung gemäß werden nun feste Metalle, z. B. Aluminium, als Dichtungsplatten verwendet, z. B. in Ringform. Solche Dichtungen sind an sich ebenfalls schon bekannt, jedoch ergeben sie in Verbindung mit Quecke, silber zu dem beanspruchten Zweck den besonderen Vorteil, daß die Restgase auf ein Minimum zurückgeführt werden.According to the invention are now solid metals, z. B. aluminum, used as sealing plates, e.g. B. in ring shape. Such seals are also already known per se, but in connection with couch grass, silver for the claimed purpose has the particular advantage that the residual gases on a Minimum.
Unter Umständen wird es sogar zweckmäßig sein, Metalle zu wählen, welche sich mit dem Quecksilber etwas amalgamieren.Under certain circumstances it will even be useful to choose metals which amalgamate somewhat with the mercury.
Als besonderen Vorteil der Verwendung von Metall gegenüber den Dichtungen aus nachgiebigem Material ist noch hervorzuheben, daß jene ihre Form weniger verändern als diese, und daß sie beim Auseinandernehmen der Elektrodenzuführungen weniger beschädigt werden als die Dichtungen aus weichem Material.As a particular advantage of using metal compared to the seals made of flexible Material should also be emphasized that the former change their form less than the latter, and that they do so when they are dismantled the electrode leads are less damaged than the seals made of soft material.
Unter Umständen erweist es sich aber als vorteilhaft, die Metalldichtungen mit den nicht metallischen Dichtungen zu vereinigen, wodurch letztere ebenfalls einen größeren Zusammenhalt erfahren.Under certain circumstances, however, it proves to be advantageous not to use the metal seals with the to unite metallic seals, whereby the latter also a greater cohesion Experienced.
