Description
Verfahren zum Entfernen der Restgase aus dem 1Vletallmantel von Entladungsgefäßen. Gemäß der Erfindung werden die Restgase aus dem Metallmantel von Entladungsgefäßen dadurch entfernt, daß man den Metallmantel mit einem Gas oder einer Flüssigkeit umgibt, welche. die Restgase leichter aufnimmt als das Metall, aus welchem der Mantel hergestellt ist, z. B. flüssige bzw. gasförmige Alkalimetalle (Natrium, Kalium).Process for removing the residual gases from the 1-metal jacket of discharge vessels. According to the invention, the residual gases are removed from the metal jacket of discharge vessels by removing the metal jacket with a gas or a liquid surrounds which. absorbs the residual gases more easily than the metal from which the jacket is made, e.g. B. liquid or gaseous alkali metals (sodium, potassium).
Die im Metallmantel enthaltenen Restgase diffundieren unter dem Einfluß der höheren Temperatur an- der Innenwand des Entladungsgefäßes nach außen und können von dort leicht -entfernt werden. Die Diffusion der Restgase nach der Oberfläche des Mietallmantels kann gesteigert werden, wenn man für eine gute Kühlung der Oberfläche sorgt. Man benutzt daher weiter erfindungsgemäß die den Mantel umgebende Flüssigkeit oder das Gas als Kühlmittel, indem man sie an dem Metallmantel vorbeiführt. Um einen übertritt der Moleküle des Gases bzw. des Dampfes der Kühlflüssigkeit nach dem Innern des Entladungsgefäßes zu verhindern, ist es zweckmäßig, sie unter so geringen Druck zu setzen, daß die mittlere freie Weglänge der Moleküle so groß ist, daß für die Bewegung derselben nach dem Innern des Entladungsgefäßes nur noch die Molekularströmung in Frage kommt.The residual gases contained in the metal jacket diffuse under the influence the higher temperature on the inner wall of the discharge vessel to the outside and can can be easily removed from there. The diffusion of the residual gases towards the surface the rental jacket can be increased if you look for a good cooling of the surface cares. Therefore, according to the invention, the liquid surrounding the jacket is also used or the gas as a coolant by passing it past the metal jacket. To one the molecules of the gas or the vapor of the cooling liquid pass inside To prevent the discharge vessel, it is useful to keep it under such low pressure to put that the mean free path of the molecules is so large that for the Movement of the same towards the interior of the discharge vessel only results in the molecular flow can be considered.
