- 12. An apparatus as recited in claim 11, wherein said means for imparting rotational power comprises an electric motor.
- 13. An apparatus as recited in claim 11 wherein said elongate pushrod further comprises a dampening mechanism.
- 14. An apparatus as recited in claim 13, wherein said dampening mechanism comprises a spring.
- 15. An apparatus as recited in wherein said dampening mechanism comprises a sensor assembly, said sensor assembly regulating said means for imparting rotational power.
- 16. An apparatus as recited in claim 13, wherein said dampening mechanism comprises a spring in combination with a sensor assembly, said sensor assembly regulating said means for imparting rotational power.
- 17. An apparatus as recited in claim 10, wherein said control mechanism comprises a sensor and corresponding actuator.
- 18. An apparatus as recited in claim 10, wherein each said door further comprises at least one counterweight.
- 19. A warp resistant feed door apparatus for a high temperature combustion chamber, comprising:a pair of warp resistant feed doors; a door opening mechanism associated with said feed doors configured to allow the synchronous opening of said doors upon activation of the mechanism, said door opening mechanism comprising: a first lever arm mounted to a first end of a first pivot shaft which is rotatably mounted to a base; a second lever arm mounted to a second hinge shaft which is rotatably mounted to said base; an elongate push rod having first and second ends, said push rod operably connected at staid first end to said first lever arm and at said second end to said second lever arm; and means for imparting rotational power to said first pivot shaft; and a control mechanism coupled to said door opening mechanism configured to activate said door opening mechanism when said feed door apparatus is aligned with a fuel delivery platform.
- 20. An apparatus as recited in claim 19, wherein said means for imparting rotational power comprises an electric motor.
- 21. An apparatus as recited in claim 19, wherein said control mechanism comprises a sensor and corresponding actuator.
- 22. An apparatus as recited in claim 19, wherein said elongate pushrod further comprises a dampening mechanism.
- 23. An apparatus as recited in claim 22, wherein said dampening mechanism comprises a spring.
- 24. An apparatus as recited in claim 22, wherein said dampening mechanism comprises a sensor assembly, said sensor assembly regulating said means for imparting rotational power.
- 25. An apparatus as recited in claim 22, wherein said dampening mechanism comprises a spring in combination with a sensor assembly, said sensor assembly regulating said means for imparting rotational power.
- 26. An apparatus as recited in claim 19, wherein each feed door comprises:a shaft rotatably coupled to a base; a plurality of anchor arms mounted to said shaft; a door plate; and a plurality of fasteners coupling said door plate to said anchor arms.
- 27. An apparatus as recited in claim 26, wherein each said door further comprises at least one counterweight.
