A transmission filter includes two outlets. One outlet, adapted to feed an engine-driven pump, protrudes diagonally from the front of the filter. The first outlet is sealed to the inlet of the engine-driven pump by a radial seal. The second outlet is arranged in a rear extension and is sealed to the inlet of an electric pump by a compression seal. The differing types of seals and relative orientations of the outlets make the assembly less sensitive to dimension variation due to production and assembly tolerances. The relative locations of the outlets also mitigate any flow interactions between the pumps when both operate simultaneously.

A suction oil filter for a transmission or combustion engine including an oil filter housing made of plastic and having at least one suction channel that can be connected to a suction side of a suction pump and at least one return channel feeding into the suction channel for a pressurized oil flow returned by the suction pump. The return channel is provided with at least one nozzle in the region of the opening thereof into the suction channel, as well as at least one pressurized oil supply pipe which is linked to the return channel and can be connected to a pressure side of the suction pump, and which is connected to the oil filter housing via at least one contour connection.

A fuel filter device includes a filter cloth and a skeletal structural member including an inner flange portion positioned inside the filter cloth and a connecting member including an outer flange portion positioned outside the filter cloth, wherein a peripheral edge portion of an opening of the filter cloth is clamped between the inner flange portion and the outer flange portion, the inner flange portion and the outer flange portion jointly defining a center hole and a center bore serving as a communication passage communicating inside of the filter cloth with outside of the filter cloth, and the inner flange portion is provided with a sealing rib to compress the filter cloth to ensure a sealing performance thereof, a welding rib to join the skeletal structural member and the connecting member with each other by welding, and a shifting preventing rib configured to restrict shifting of the filter cloth.

The disclosed technology includes systems and methods for water filtration. In one implementation, a system includes a water receptacle to house unfiltered water, the receptacle including an aperture located in a sidewall, a valve component located on an exterior surface of the sidewall in alignment with a filter housing located on an interior surface of the sidewall filtrate the unfiltered water. In one implementation, a method includes filling a water receptacle with unfiltered water, filtrating the unfiltered water through a filter housing in the water receptacle to obtain filtered water, and moving the filtered water from the filter housing and out of a valve component connected to a first end of a filter housing.

Methods and apparatus providing for the isolation of an unknown mutation from a sample comprising wild type nucleic acids and mutated nucleic acids through the application of time-varying driving fields and periodically varying mobility-altering fields to the sample within in an affinity matrix.

A fluid filter includes a body portion and a filter membrane portion. The body portion includes at least one aperture formed therein, wherein the filter membrane portion is disposed in the at least one aperture to filter contaminants from a fluid (e.g., a lubricant). The fluid filter is installed in a fluid passage of scroll compressor, wherein an axial movement of the fluid filter is restrained.

Flow control elements (FCEs) and fluid apparatus including the same are described. In embodiments the flow control elements (FCE) include a body that includes a front side, a back side, a left side, and a right side. The body further includes a base region, an upper region, and an intermediate region between the base region and the upper region. The FCE is configured to move in response to a fluid flow (or, more specifically, a pressure differential across the FCE) to regulate a flow of fluid past the FCE. In embodiments the FCE is included in a fluid apparatus for a vehicle, such as but not limited to a suction filter for a vehicle transmission.

Systems and methods for filtering unpurified water using modular filtration units are disclosed. According some embodiments of the invention the modular filtration unit may include a modular removable filtration cartridge with pressed non-woven geotextile fabrics and a frame assembly, and a filtration container. The filtration container holds the modular removable filtration cartridges and has walls that form a basin. A first wall has an inlet for receiving water into the filtration container and a second wall has an outlet for draining water out of the filtration container. The water is filtered by the modular removable filtration cartridges as it flows across the basin from the inlet to the outlet. The modular filtration units may be combined together to form a zoned filtration assembly, which may be inserted into the hull of a floating swimming pool. The zoned filtration assemblies may filter natural water as it fills the swimming pool.
