Methods and apparatuses for screening are provided. Embodiments include a screen basket apparatus for screening material, comprising a grid frame having a plurality of openings arranged in a lattice and a plurality of screening cartridge assemblies affixed to the grid frame to cover the respective openings of the grid frame. The screening cartridge assembly includes a case and a screen assembly fitted into the case, and may be affixed to a set of transversal member of the grid frame. The case may be formed of a single injection molded piece integrally formed by injection molding one of a polyurethane or a thermoset polymer. The screening elements together form a generally continuous screening surface across the exterior of the grid frame, which reduces blinding and is resistant to wear and tear.

A receiver dryer includes a first body and a second body, one end of the second body away from the first body defining first and second connecting ports. The receiver dryer includes a filter cartridge including a first mating portion, a second mating portion, and a filter part at a middle portion; the first mating portion fits with an inner wall of the second body, one space allowing refrigerant to flow is formed between the filter part and the inner wall of the second body, the second mating portion is connected to the second connecting port, the space between the filter part and the inner wall of the second body communicates with the first connecting port, an inside of the filter part communicates with the second connecting port via the second mating portion, and refrigerant is filtered at least once when flowing between the first and second connecting ports.

A device (10) for transporting solids that comprises—a support frame (11), —an auger (15) connected to the support frame (11) rotatably about an axis of rotation, —a motor unit (30) configured to activate in rotation the auger (15) that comprises an output shaft (321) being rotatable about an axis of revolution (B), characterized in that the axis of revolution (B) of the output shaft (321) is parallel and eccentric to the axis of rotation (A) of the auger (15).

A fuel filter device for operation in a position under non-extreme conditions, when there is enough time for replacement of the clogged filter element, or in a reverse position in a fuel bypassing state for non-stop operation under extreme conditions, when there is no time for replacement of the clogged filter element. The device consists of cup-shaped members, which are interconnected through a threaded connection and form a cavity that contains a spring compressed between the bottom of an opening of one of the cup-shaped members and an abutment formed between two openings of another cup-shaped member. The compression force of the spring is applied to a seal ring placed into an annular groove formed in the abutment surface through a flange of the filter element. Another improved sealing feature is provided by a second seal ring, which seals the threaded connection, when the connection is tightened.

A flat filter for water treatment is provided. The flat filter for water treatment according to one embodiment of the present invention comprises: filtration members formed in the shape of a plate having a predetermined area; support frames, which are coupled to the rim sides of the filtration members so as to support the filtration members, and have channels into/in which filtered water produced through the filtration members flows and moves; and gap adjustment members coupled to the support frames so as to adjust the gap between the filtration members adjacent to one another.
