Abstract: A filter within a filter cartridge design is described that includes a sealing structure on an endplate of an outer filter element. Generally, the sealing structure includes an annular flange on the endplate that can directly seal against an interior surface of a housing when the filter cartridge is assembled for use. During filtration, the annular flange prevents a working fluid from bypassing the outer filter element. The sealing flange can seal with the housing in a press fit engagement.

Abstract: A fluid pumping system with energy recovery features may provide feed water to a reverse osmosis unit. The system includes an electronic controller unit that regulates the output of three hydraulic pumps. Each hydraulic pump drives the movement of a piston in a cylinder. The pistons collectively deliver a generally constant flow of high pressure feed water. Valve bodies direct reverse osmosis concentrate to the back sides of the pistons. The electronic controller coordinates the output of the hydraulic pumps with the actuation of the valve bodies. Movement of the pistons is controlled, in part, by a feed back loop to verify the desired hydraulic pump output. Valve bodies are designed to begin closing when an associated piston velocity decreases. The valve body moves after a dwell period when an associated piston should not be moving. The piston and cylinder are designed for exposure to high salt-content water.

Abstract: An agricultural implement is provided that includes a hitch assembly configured to couple the agricultural implement to a tow vehicle, and a carrier frame pivotally coupled to the hitch assembly.

Abstract: A system and method for providing a fuel cell stack purge to remove excess water during system shut-down. A compressor is operated at a shut-down speed to force water out of the cathode flow channels and draw water through the membrane from the anode flow channels so that a desired amount of water is removed from the fuel cell stack without over drying the membrane. The cathode shut-down purge flow can be introduced in the forward or reverse direction. Further, the flow of hydrogen fuel can be directed so that it flows through the anode flow channels in an opposite direction to push water out of an anode outlet manifold into the anode flow channels so that it will also be drawn through the membrane by the cathode airflow. Finally, a brief rehydration step is added after the shut-down purge to achieve the desired water content in the cells.
