    Abstract: An electron discharge device has a hermetic pinch seal formed by an indium type pressure seal. A method and apparatus for the manufacture thereof are also described. The apparatus comprises a demountable vacuum system having a removable top with ports therein, in one of which is mounted the envelope of the device being manufactured and in the others of which are mounted other envelopes. A rotatable and reciprocable platform in the vacuum chamber carries an evaporator for forming a photoelectric layer in the envelope and an electron gun on a pinch for sealing into the envelope. The platform also carries a test electron gun the beam from which is scanned over the photoelectric layer to test it, and an oven for baking the lower part of the envelope of the device. The various devices mounted on the platform are raised so that they enter respective envelopes for the purpose of degassing them.

    Abstract: AN APPARATUS INCLUDING A ROTATABLE SUPPORT FOR HOLDING A CATHODE-RAY TUBE COMPONENT, FOR EXAMPLE, A FUNNEL COMPRISING A SEALING SURFACE HAVING A CLOSED CONFIGURATION IN CLUDING RADIUSED CORNERS, AN INNER BORDER, AND AN OUTER BORDER, A MEANS FOR ROTATING THE SUPPORT, A SEALING-MATERIAL CONTAINER HAVING A BOTTOM OUTLET, A MEANS FOR TRACKING THE SEALING SURFACE WITH THE CONTAINER ALONG A FIRST PATH ON THE SIDES OF THE SEALING SURFACE, AND A MEANS FOR TRACKING THE SEALING SURFACE WITH THE CONTAINER ALONG A SECOND PATH DISPLACED TOWARDS THE OUTER BORDER ON THE CORNERS OF THE SEALING SURFACE. METHOD INCLUDES POSITIONING SEALING SURFACE OF THE CATHODE-RAY TUBE; FOR EXAMPLE, A FUNNELSEALING SURFACE IN A HORIZONTAL PLANE, MOVABLY POSITIONING A CONTAINER HAVING A BOTTOM OUTLET OVER THE SEALING SURFACE, ROTATING THE SEALING SURFACE ABOUT THE CENTER OF THE CLOSED CONFIGURATION, TRACKING SAID ROTATING SEALING SURFACE WITH THE OUTLET ALONG THE FIRST PATH, APPROACHING THE BEGINNING OF THE CORNERS OF THE SEALING SURFACE GRADUALLY MOVING THE OUTLET FROM THE FIRST PATH TO THE SECOND PATH, TRACKING THE ROTATING SEALING SURFACE WITH THE OUTLET ON EACH OF THE CORNERS AT THE SECOND PATH, APPROACHING THE ENDING OF EACH OF THE SEALING SURFACE CORNERS GRADUALLY MOVING SAID OUTLET FROM THE SECOND PATH TO THE FIRST PATH, AND DURING ROTATION DISPENSING A BEAD OF SEALING MATERIAL AT A UNIFORM RATE ON THE SEALING SURFACE.

    Abstract: A method of sealing a metallic wire between two vitreous parts. The wire is positioned so that its ends extend outwardly from opposite sides of the enclosure formed by the parts. The adjacent side edges of the parts are formed with protuberent lips which surround the portion of the wire adjacent one end thereof. The parts are preheated, in a controlled atmosphere. A laser beam is then focused on the one end of the wire to fuse it and thereby also fuse, by contact heat transfer, the side portions of the vitreous parts which are adjacent the wire. The wire is thus welded in the enclosure with the fused protuberent lips forming an outwardly extending enclosure portion which reinforces the seal in the area adjacent to the fused wire.
