Abstract: A continuous belt screen assembly and related methods of controlling flow through the continuous belt screen assembly. The continuous belt screen assembly has a base, opposed sides, an inlet and at least one outlet. The assembly, in use, is arranged in a channel having a pair of opposed walls and containing a liquid. A flow restrictor for the continuous belt screen assembly includes a body mountable to a downstream end of the assembly to restrict the liquid flowing out of the at least one outlet. The body defines at least a portion of at least one aperture configured to control a level of the liquid upstream of the body.

Abstract: A locking assembly is provided for a cover. The cover is a substantially rigid cover configured to close off an opening to a void, said void bounded by a side wall. The cover defines a top side and an opposed underside. The locking assembly includes a mounting arrangement mountable to the underside. A link is pivotally connected to the mounting arrangement. The link defines a first end and a second, free end. A locking member is carried by the second, free end of the link. The locking member frictionally engages the side wall of the void in a locking position, in use. An actuating member connects to the link and is accessible via the top side. The actuating member displaces the link relative to the mounting arrangement to cause the locking member to frictionally disengage from the side wall of the void to a disengaged position.

Abstract: A sieve bend can include a support structure supporting a screening arrangement. The screening arrangement can include a first screening segment having a first screening element configuration and at least one further screening segment having a second screening element configuration different from the first screening element configuration.

Abstract: A screen includes a support structure. A plurality of elongate screening elements are arranged in spaced relationship transversely on the support structure to define elongate screening apertures between adjacent screening elements. Each screening element has a screening head defining a screening surface, the screening surfaces all being at the same height relative to the support structure. Adjacent screening elements are of different widths relative to each other with a transverse dimension of the aperture being less than a width dimension of the wider screening element. The screening head of the wider screening element is shaped to maintain a substantially constant screening aperture between the screening elements during a predetermined amount of wear of the wider screening element.

Abstract: A separation panel includes a body member defining a separation surface and an opposed surface with a plurality of apertures extending through the body member and opening out into the separation surface and the opposed surface of the body member. The body member is made up of a plurality of discrete elements secured together to form substantially hexagonal apertures. A securing arrangement secures the discrete elements together.

Abstract: A screen includes a support structure. A plurality of screening elements is arranged in spaced relationship on the support structure to define screening apertures between adjacent screening elements. Each screening element defines a screening surface, respectively. The screening surface of each of at least some of the screening elements are spaced further from the support structure than the screening surface of each of the remaining screening elements so that, on opposed sides of each screening aperture associated with the at least some of the screening elements, the screening surfaces are at different heights.

Abstract: A screen assembly may include a frame defining an aperture, a screen panel disposed within the aperture, the screen panel having a plurality of slots formed therethrough that extend between top and bottom surfaces of the screen panel, and an RFID tag disposed within a recess formed in an edge of the screen panel, the edge being between the top and bottom surfaces.
