Abstract: A method and apparatus for positioning an article having opposed ends at least one of which is flat and an irregular surfaced body portion between the ends so that the article can stably rest on the flat end including feeding one or more of such articles to a substantially horizontal support surface in random orientation and imparting a simultaneous back-and-forth and side-to-side motion on the surface with the resulting forces on each article created by such motion causing each article to seek a stable position bringing each article to rest on the flat end of the article.

Abstract: A method of making a safety vent in an hermetically sealed electro-chemical container device and a novel container portion including such safety vent comprising a unique series of steps including printing a preselected area of the container portion with a masking resist pattern having an uncovered planar area of preselected geometric configuration corresponding to a safety vent area for the container portion and etching the uncovered area to a preselected uniform material thickness to provide a safety vent in the container portion capable of withstanding a preselected pressure before profound and instantaneous rupture.

Abstract: A hermetic terminal assembly for a motor unit housing including a cup-shaped body, the bottom of which has a rim and at least one hole defining an annular sealing lip extending in the same direction therefrom through which hole an electrical connection pin extends in sealed relation thereto with the pin insulated by a protective insulating extension sleeve bonded to a sealing insulator, the extension sleeve being formed relative the sealing insulator member and lip extremity to contact the outer periphery of the lip to remove possible sealing insulator cracking to a position removed from the pin.

Abstract: An improved hermetic terminal pin for conducting electrical current including a stop flange and fuse-like and locking groove areas adjacent thereto and a method and apparatus for manufacturing the terminal pin including the steps of feeding a wire material of preselected composition from a storage area to a cutting area and then to a roll forming area, the apparatus including die means to accomplish the roll forming step.

Abstract: A modified terminal pin and end closure structure for the housing of a hermetic terminal assembly and method of manufacturing the same, the structure including an apertured end closure with a peripheral wall surrounding the aperture and extending into the housing with the free end of the wall cooperatively overlapped in aperture sealing relation by a terminal pin carrying eyelet.

Abstract: An improved terminal pin and end closure structure for an hermetic terminal assembly and method of making the same, the structure including an apertured end closure with a peripheral wall surrounding the aperture to extend at preselected angle from the end closure, the aperture being covered by a sealed terminal pin carrying sealing member which is sealed to the extended peripheral wall.

Abstract: A hermetic terminal assembly wherein a radially extending flange on a current conducting pin that extends through a hole defined by a cover member adapted to be secured to an opening in a motor housing is surrounded by an electrically insulating sleeve with the inner axial extremity of the sleeve extending at an axial location relative the pin substantially beyond the inner face of the radially extending flange to provide an extended tortuous path between the flange on the pin and the cover member, the pin having a reduced neck portion on the inner end thereof adjacent the inner face of the flange to provide a fuse-like area.

Abstract: In a glow plug igniter of the type used in internal combustion engines, having a hollow cylindrical casing and a central pin-terminal, a substantially flat-spiral-coiled, flexible resistance element, oriented perpendicularly to said pin-terminal with one end electrically connected to the casing and the other to the pin-terminal, is positioned at a nose end of the casing and spaced from but close to a backing seal of temperature and corrosion-resistant material. At least one seal hermetically closes the hollow casing. Preferably, spaced glass seals constitute the sole means for mounting the pin in the body.

Abstract: In a glow plug igniter of the type used in internal combustion engines, having a hollow cylindrical casing and a central pin-terminal, a substantially flat-spiral-coiled resistance element, flexible in a direction out of its plane, oriented perpendicularly to the pin-terminal with one end electrically connected to the casing and the other to the pin-terminal, is positioned at a nose end of the casing and spaced from a backing seal of temperature and corrosion-resistant, electrically insulating material hermetically closing the hollow casing. An idle bar of substantial width relative to the resistance element, bridges across the nose end of the casing, spaced from the resistance element. Preferably, the casing is crenellated, with opposed merlons, provided with weld projections, to which the ends of the idle bar are welded.
