摘要： A filter mesh assembly (100) configured to control particulate material in a filter assembly (100) of a plastic extruder. The filter mesh assembly (100) includes a wire mesh filter having a square weave construction defining a predetermined pore size with the wire mesh filter having flattened surfaces of adjacent wires on the same plane and configured to allow a portion of the scraper (116) to move across the wire mesh filter assembly (100). The assembly (100) also includes a wire mesh supporter having a square weave construction and a characteristic of sufficient strength to support the wire mesh filter against a breaker plate (112). The wire mesh filter and the wire mesh supporter are diffusion bonded to each other as a unified structure and disposed in a housing between an inlet and breaker plate (112). The configuration allows passage of molten plastic through the breaker plate (112) and lateral movement of material, parallel to the breaker plate (112).

摘要： An extended area filter is provided. The extended area filter has sheets of a filter media configured for increased filter media surface area. A plurality of filter media tubes are position in a concentric arrangement about a longitudinal axis of the filter, defining annular inlet volumes and annular outlet volumes, the annular inlet volumes receiving an unfiltered fluid, and the outlet volumes receiving a filtrate passed through the tubes of filter media. Internal support elements suitable for placement within the outlet volumes are also provided. A filter apparatus configured for filtering a contaminated fluid and employing extended area filters of the invention is also provided.

摘要： A particle control screen assembly for a perforated pipe used in a well. The particle control screen assembly includes a screen with a first end and a second end. The screen includes a first and a second unsintered woven mesh layer, each layer having a first longitudinal edge and a second longitudinal edge. The cylindrical screen also includes openings sized to prevent passage of particulate material and a longitudinal metal weld adjacent the first and second longitudinal edges of the first and second unsintered woven mesh layers. The longitudinal metal weld secures the edges of the unsintered woven mesh layers together. The particle control screen assembly also includes a weld-compatible metal structure adjacent the first end of the cylindrical screen. A circumferential metal weld between the cylindrical screen and the metal structure bonds a portion of the metal structure and a portion of the cylindrical screen.

摘要： A particle control screen includes a support layer. A first filter layer is disposed around the support layer. A second filter layer is disposed around the first filter layer. A third filter layer is disposed around the second filter layer. Each of the filter layers has a pore size. The pore size of the third filter layer is greater than the pore size of the second filter layer. The pore size of the second filter layer is greater than the pore size of the first filter layer.
