Method of diffusing gas into a sealed vessel and a device for carrying out the method

摘要: There is disclosed a method of diffusing gaseous medium such as tritium into vessel tube an overvoltage protector. According to the method, including wall portion made material permitting diffusion gas therethrough provided. This heated predetermined elevated temperature and sealed while at temperature. The thereupon evacuated exposed atmosphere be diffused maintaining this for period time less than sealing pressure higher within vessel, thereby causing filling same with gas. also device carrying out hereinbefore described method.
