Abstract: A swimming pool skimmer includes a float having skimming foil attached thereto. The skimming foil projects above the surface of the water to receive leaves and other debris thereover for deposit and retention in a receptacle. The receptacle may comprise a removable screen mounted below the float.

Abstract: A "load-plus" valve is oftentimes utilized in the servo-system for a variable displacement pump to maintain pump discharge pressure above a minimum pressure level and above a load pressure in a fluid actuator. Valves of this type normally employ a spring interconnected between a modulating spool and a piston which is responsive to load pressure to modulate a control pressure, controlling the displacement of the pump. Valves of this type thus provide a constant discharge pressure margin over load pressure while also providing the pump's minimum stand-by pressure. However, valves of this type further provide pump packages which are somewhat bulky in design. The improved load-plus valve (22) of this invention provides a spool (49) movable between a first position communicating a control pressure (P.sub.

Abstract: A control arrangement comprises a pivotal control member having a pair of arms and a pivotal lever disposed between the arms. The stop member is secured on the lever to engage a snubber upon relative pivoting between the control member and lever. The control arrangement is adapted for connection to a control valve to alert the operator when the control lever has over-travelled a "run" condition of operation when the stop member engages the snubber.

Abstract: This invention pertains to a control valve (14) having a double-acting kick-out member (36) attached to an end of a spool (33) thereof to return the spool (33) to a neutral position after actuation thereof. The invention is particularly useful in a fluid control circuit (10) wherein the control valve (14) is adapted to selectively communicate pressurized fluid to an actuator (13), such as a double-acting hydraulic cylinder.

Abstract: Fuel injection apparatus often uses valves which rapidly move in a start and stop motion for the purpose of starting and stopping injection. Undesirable inertial forces result from such start-stop movement of the valves. To limit such undesirable forces, a pair of valves (72,92) are provided for continuous rotation for starting and stopping injection.

Abstract: A laminated spacer plate (10) for engines, pumps and the like comprises a plurality of metallic sheets (11-14), each having openings (15,16,17,24,40) preformed therethrough and secured together. The preforming of the openings through the individual sheets facilitates intercommunication of certain of the openings with passages formed within the spacer plate and eliminates the need for costly machining and related manufacturing operations normally required for the fabrication of a one-piece spacer plate.

Abstract: A modular truck body comprises unitary first and second modules having bottom sections thereof secured together at a separation line which is substantially offset laterally from a longitudinal axis of the truck body. The width of the first module is thus substantially larger than the width of the second module. The modules are aligned and preassembled at a manufacturing plant by releasably securing them together at the separation line therebetween. The modules are then disassembled and shipped to a remote job site or the like for final reassembly and securance of the modules together.
