  • Rabbet mounted combustor
    Publication number: 20040261419
    Abstract: A combustor includes an outer wall and an inner liner joined to an inner shell in turn mounted to an inner casing. The casing includes a first rabbet at an end flange in which is mounted a corresponding flange of the inner shell. The inner shell also includes a second rabbet which receives an end flange of the inner liner. The inner shell is trapped in the first rabbet by an inner retainer. And, the inner liner is trapped in the surrounding second rabbet for aft-mounting the liner and shell to the inner casing.

  • Sector staging combustor
    Publication number: 20040221582
    Abstract: A combustor includes outer and inner liners joined together by a dome to define a combustor chamber. A row of air swirlers is mounted in the dome and includes corresponding main fuel injectors for producing corresponding fuel and air mixtures. Pilot fuel injectors fewer in number than the main injectors are mounted in the dome between corresponding ones of the swirlers. Staged fuel injection from the pilot and main injectors is used for starting the combustor during operation.

  • Locking pliers with axial clamping action
    Patent number: 5456144
    Abstract: A pair of locking pliers includes a body having a fixed jaw that supports a fixed extension. A movable jaw is pivotably mounted to the body by a hinge pin, and the movable jaw includes a movable extension. An operating lever is pivotably mounted to the movable jaw to close the movable jaw, and the movable jaw is shaped such that the movable extension slides along the fixed extension as the movable jaw is pivoted closed with the operating lever in order to provide an axial clamping action.
