  • Electrical resistance ignitor with spaced parallel filaments brazed in refractory block recesses
    Patent number: 5471032
    Abstract: An ignitor for fuel gas burners formed of a plurality of spaced parallel filaments of SiC coated Carbon (C) high temperature brazed with Chromium Silicide in grooves provided in a refractory base block of Aluminum Oxide and Silicon Oxide. Terminal posts of IVIoSi are embedded in the high temperature braze. Stainless steel lead attachment pads are nickel-chrome brazed to the posts at a lower temperature. Removable notched graphite bridges and graphite hold-down blocks position the filaments during the high temperature brazing.

  • Method of making a resistance ignitor for igniting gaseous fuel
    Patent number: 5218751
    Abstract: Filamentary material having a core of elemental carbon covered with a coating of silicon carbide material with a thin outer layer of elemental carbon is heated in air to cause the outer layer to oxidize. The filament is then cut to segments of a desired length, bundled and the ends metallized. A tubular metal connector is crimped over each of the metallized ends of the bundle with a conductive lead extending therefrom. The bundle assembly is then mounted onto a refractory holder.
