Abstract: A manual post puller mechanism having a lever extendable for increasing the amount of leverage applied for pulling the post from the ground, the lever being securable within a base and serving as a handle graspable by the operator for carrying the mechanism between locations. A chain extends downwardly from a chain engaging front portion of the lever which includes slots that allow the position of the chain to be adjusted so as to vary the amount of leverage applied to the post. A post holder mechanism carried at the bottom of the chain engages the post and defines an enclosed generally rectangular opening that receives the post. A pair of pivot plates coupled with the lever generally hinder an operator's fingers from being pinched during post pulling operations.

Abstract: A pressure-actuated valve of the type used in the fuel systems of gas turbine engines and the like combines the functions of check valve and metering valve in a housing forming a single assembly. A movable valve actuator is slidably movable along a central axis within the housing, The actuator has two spaced-apart valve faces that cooperate with two spaced apart valve seats mounted to the housing. One of the valve-seat/valve-face combinations controls flow through a primary outlet port from the housing, and the second combination controls fluid flow through a separate, secondary outlet. The second valve combination includes telescopically mating inner and outer wall surfaces having a metering passage in the outer wall characterized by a transverse cross-section that varies from a minimum to a maximum at its opposite ends. As the inner and outlet wall surfaces move relative to each other, the exposed cross-section of the metering passage increases to permit increased flow through the valve.
