    Abstract: A seal is provided for sealing a quartz envelope to a glass stem in an electron tube. The seal includes an intermediate annular metallic stress relieving ring disposed between the quartz envelope and the glass stem. The annular metallic stress relieving ring has: a radial flange portion, plated with a noble metal and sealed to a silver plated surface of the quartz envelope by a silver chloride cement; a supporting thin narrow relieving portion connected and extending substantially perpendicular to the radial flange portion; and a stem sealing portion which is sealed to the glass stem by conventional sealing techniques and which is interconnected with the annular stress relieving portion.

    Abstract: An improved camera tube of the vidicon type has a field mesh accurately mounted between the target and the electron beam gun. The mesh is mounted in a manner to permit accurate spacing and parallel alignment with the target surface and to permit external electrical connections with the field mesh to be made without disturbing the electrical fields within the tube, providing a low inductance contact to the mesh particularly useful in high resolution tubes.

    Abstract: A hermetically sealed electrical connector capable of operation in temperatures from -55* to 225* C. As disclosed, it comprises an outer shell of light weight aluminum alloy, surrounding copper contacts extending through a glass insulator supported within the shell; the shell, the insulator, and the contacts being made from materials having specified coefficients of thermal expansion and yield strength effective to avoid destruction of the integrity of the seal by thermal expansion and contraction.
