Definitions

  • a cathode-ray device comprising a body portion defining an interior volume; a housing portion for a replaceable cathode fitted to said body, said housing having a pair of openings between which extends a space for receiving a cathode, one of said openings serving to allow insertion of said cathode into said space and the other of said openings allowing passage ofelectrons emitted by said cathode into said body portion, said body portion having a volume of the order of 10,000 times that of said cathode receiving space; and a vacuum lock for preventing airflow simultaneously through said openings, said vacuum lock comprising first and second closure means adjacent said one and said other opening and operable to close off said one and said other opening respectively and means interlocking said first and second closure means to prevent both closure means being simultaneously open, and said first closure means comprising a sealing ring disposed about said one opening, an apertured member cooperable with said sealing ring to close off said one opening, means mounting said member to have linear movement toward and away from said sealing ring to engage
