Abstract: An improved fuse associated current conducting pin and sealing structure for a hermetic terminal assembly wall wherein the sealing member has a preselected coefficient of expansion compatible with that of the pin and wall and a softening point temperature in excess of the conducting temperature of the pin surface occasioned by fuse melting.

Abstract: A method for, and product of manufacturing vessel lid covers including electrically conductive pin assemblies for vessel container housings including pre-plating both the lid covers and pins in a first area and forming the pre-plated lid covers with their pin assemblies in a second area with selected portions of the lid covers being freed of plating during the process to enhance pin assembly fusing and the product formed.

Abstract: An electrical conductor pin assembly including at least one conductor pin having pin insulation, the conductor pin extending in sealed relation through a housing wall terminal assembly of a chamber and a lead wire connector block having an over-surface wall shield assembly extending from the outer face of the connector block configured to spacedly surround both the exposed pin assembly and pin insulation to provide tortuous passageways therebetween, the conductor pin of the assembly force fitting with a passageway in the connector block through a thin breakaway membrane with the wall shield assembly being in sealed relation wit the terminal assembly.

Abstract: An improved fuse associated current conducting pin and sealing structure for a hermetic terminal assembly wall wherein the sealing member has a preselected coefficient of expansion compatible with that of the pin and wall and a softening point temperature in excess of the conducting temperature of the pin surface occasioned by fuse melting.

Abstract: A conductive pin assembly arrangement for a wall opening of a machine housing including a removable plate in sealed relation to the wall opening, the plate having at least one opening extending therethrough, and a conductive sleeve and pin assembly extending longitudinally through the plate in sealed relation to the plate with one end of the pin in the housing and the opposite end outside the housing.

Abstract: A hermetic terminal assembly arrangement for an opening extending through a wall housing panel wherein the opening periphery is threaded to adjustably receive an externally threaded annular sleeve through which a current conducting pin extends, the terminal assembly arrangement including a first seal between the pin and annular sleeve and a second compressible seal between the sleeve and housing.
