Description

Verfahren zur Herstellung von Elektroden für Bogenlampen, die zur Körperbestrahlung dienen Es ist bekannt, in Bogenlampen, die zur Bestrahlung des menschlichen Körpers dienen, kleine Elektroden zu verwenden, die im Trockenpreßverfahren aus nicht oder schwer oxydablen Stoffen, wie beispielsweise Metalloxyden, hergestellt sind.Process for the manufacture of electrodes for arc lamps used for Serve body irradiation It is known in arc lamps that are used to irradiate the human body are used to use small electrodes made in the dry pressing process made of non-oxidizable or poorly oxidizable substances, such as metal oxides are.

Elektroden dieser Art sind erfindungsgemäß dadurch verbessert worden, daß sie nach der Trockenpressung hoch gesintert werden. Die im bekannten Trockenpreßverfahren hergestellten Elektroden werden also in einem Ofen langsam auf sehr hohe Temperatur gebracht und eine Zeitlang dieser hohen Temperatur ausgesetzt. Electrodes of this type have been improved according to the invention by that they are highly sintered after dry pressing. The known dry pressing process The electrodes produced are slowly brought to a very high temperature in an oven brought and exposed to this high temperature for a while.

Der neue weitere Verfahrensschritt der Hochsinterung hat den großen Vorteil, daß eine sehr große Homogenität der Elektrode erreicht wird, die es beispielsweise ermöglicht, die Elektrode sowohl für Gleich- als auch für Wechselstrom zu verwenden, was hei den I,isher bekannten, nicht gesinterten Elektroden dieser Art immer große Schwierigkeiten verursachte. The new further process step of high sintering has the big one Advantage that a very high homogeneity of the electrode is achieved, which it for example enables the electrode to be used for both direct and alternating current, what is called the I, isher known, not sintered electrodes of this kind always large Caused trouble.

Außerdem ist durch das neue Verfahren weiterhin die mechanische Festigkeit der Elektrode erhöht worden; auch zeichnet sie sich durch einen verhältnismäßig langsamen Abbrand aus. In addition, the new process still increases the mechanical strength the electrode has been increased; it is also characterized by a proportionate slow burn off.
