  • Patent number: 5856651
    Abstract: An ignitor assembly includes a hot surface ignitor of a resistance material and a super alloy shield surrounding the ignitor. The shield comprises a longitudinally extending cylindrically shaped super alloy sheet having a plurality of first and second alternating transverse strips. The strips are formed by making a plurality of transverse slits or cuts in a flat sheet of super alloy material. The first alternating strips are bowed outwardly in a first direction and the second alternating strips are bowed outwardly in an opposite direction to thereby form a cage like cylindrical structure which forms a part of the ignitor assembly. The ignitor generally includes a base portion and is inserted into the cage like structure.
