Abstract: The present disclosure provides a seal bar. In an embodiment, the seal bar comprises a base member having a flat front surface and a flat recessed surface a distance (d) behind the front surface. The front surface defines an x-axis, X. The flat recessed surface has a first endpoint (A1), wherein an axis that is perpendicular to the flat recessed surface at the first endpoint (A1) defines a first y-axis (Y1). The seal bar has a concave surface extending the distance (d) between the first endpoint (A1) and a point (B1) on the flat front surface. The concave surface defines a quadrant arc segment of an ellipse between the first endpoint (A1) and the point (B1).

Abstract: The present disclosure provides a flexible container. In an embodiment, the flexible container includes a first multilayer film and a second multilayer film. Each multilayer film comprises a seal layer. The multilayer films are arranged such that the seal layers oppose each other and the second multilayer film is superimposed on the first multilayer film. The multilayer films are sealed along a common peripheral edge. The flexible container includes a fitment. The fitment comprises a base. The base comprises a polymeric blend of from 60 wt % to 90 wt % ethylene/?-olefin multi-block copolymer and from 40 wt % to 10 wt % high density polyethylene (HDPE). The flexible container includes a fitment seal comprising the base located between the multilayer films. The base is sealed to each multilayer film at a portion of the common peripheral edge.

Abstract: A cross-flow filter assembly (10) including: a cylindrical filter (12) having an inner periphery (14) enclosing filter region (26) extending along an axis (X) from an opposing feed end (16) and an effluent end (18); and a cleaning assembly (32) axially-aligned within the filter region (26) and comprising at least one radially extending cleaning member (34) biased against the inner periphery (14) of the filter (12), wherein the cleaning assembly (32) is adapted to rotate about the axis (X) to remove debris from the inner periphery (14) of the filter (12); and is characterized by a compressive member (40) providing a continuous radially outward force that biases the cleaning member (34) against the inner periphery (14) of the porous screen (24).

Abstract: A hydroclone comprising: a tank (12) including a fluid inlet (14), a filtered fluid outlet (16) and an inner peripheral wall (22) enclosing at least one chamber (24); a filter assembly (26) located within the chamber (24) and comprising a circular filter screen (27) centered about an axis (X); and a cleaning assembly (48) comprising at least one cleaning member (52) biased against and adapted to rotate about the periphery (29) of the filter screen (27); and at least one of: a) the filter screen (27) is reversibly deformable a radial distance (D) of from 0.1 to 10 times the average pore size by the cleaning member (52) biased against the periphery (29) of the filter screen (27); and b) a compressive member (58) providing a continuous radially inward force that biases the cleaning member (52) against the periphery (29) of the filter screen (27).
