In a conductor seal assembly, in which a conductor is sealed in place by a glass seal, a ceramic baffle plug is mounted on, and surrounds the conductor and is sealed at one end to the glass seal, preferably by fusion of the glass seal.

Conductor seal assembly

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.

Glow plug

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.
