    摘要： An improved adjustable relief valve is provided having a valve body with a valve body inlet and outlet disposed therein. A reciprocating plunger is disposed in said valve body, and is movable between a first closed position isolating said valve body inlet and outlet, and a second open position communicating said valve body inlet and outlet. A pilot valve means is operatively associated with said plunger to control the flow of fluid from said valve body inlet to said plunger. Both said plunger and said pilot valve means have adjustable spring means for urging them toward their respective closed positions. An auxiliary means is provided for opening said relief valve without varying the adjustments of said spring means, so that said relief valve may be purged with a cleansing fluid.

    摘要： A theater seat assembly includes a pair of opposed stanchions for attachment to a support surface, a generally horizontal seat portion disposed between and operatively connected to the stanchions, and a generally upright back portion disposed between and operatively connected to the stanchions. The theater seat assembly may include a lounge mechanism operatively connected to the back portion and the stanchions to allow the back portion to lounge rearward relative to the stanchion. The theater seat assembly may also include a cushion suspension system operatively connected to the seat portion and the stanchions to allow the seat portion to deflect downwardly relative to the stanchions. The theater seat assembly may further include each one of the seat portion and the back portion having a frame, a cushion disposed adjacent the frame and a trim cover covering the cushion and attached to the frame.
