In-pipe inserts for piping systems and related methods are described herein. An example filter insert includes an end plate having a set of openings, a set of filter tubes extending from a first side of the end plate, and a set of support rods extending through respective ones of the channels of the filter tubes. The support rods extend through the openings in the end plate. The filter insert also includes a first retainer disposed on a second side of the end plate. The first retainer is coupled to the support rods at or near first ends of the support rods. The filter insert further includes a second retainer coupled to the support rods at or near second ends of the support rods opposite the first ends such that the filter tubes are clamped between the end plate and the second retainer.

A method for assembling a bezel unit with a base unit installed in an article includes inserting a foot of a first attachment leg extending from a first position on the bezel unit into a first receiving cavity including by movement of the bezel unit in a first direction and moving the bezel unit in a second direction normal to the first direction. Moving the bezel in the second direction causes mutual engagement between an exterior profile of the foot with an inside profile of the cavity, both the exterior profile of the foot and the inside profile of the cavity tapering inwardly in the second direction. The mutual engagement between the first exterior profile and the inside profile aligns the bezel unit with the base unit with respect to the first and second planes.

Equipment for sucking and extracting anodic sludge from cells for electro-refining or electro-winning of metals that allows the continuous and selective extraction of anodic sludge without interrupting electro-refining or electro-winning, preventing the anodic sludge from causing contamination in the copper cathodes and in the time in later stages of metal recovery, where the equipment comprises: a vacuum tank (2) that receives the extracted anode sludge, comprising an outlet valve (21) located in its lower part; a filter (25) resistant to acid (25) inside the vacuum tank (2) for the separation of the anode sludge from the sucked electrolyte so that the anode sludge remains in the filter (25) by a decantation process while the electrolyte passes to the lower part of the tank body; a vacuum system (3), connected to the vacuum tank (2), which generates a vacuum inside the vacuum tank (2) to generate the suction or vacuum aspiration of the equipment; and an anode sludge collector (1) comprising a transparent tube (11) where a first end (12) has a suction nozzle (14) connected, through which the anode sludge enters, and a second end (13) is connected to the vacuum tank (2); a regulating valve (15) mounted at or near said outlet end (13) of the transparent tube (11), which is in communication with the interior of the transparent tube (11) at one of its ends and at atmospheric pressure at the another end, where said regulating valve (15) allows the regulation of the suction pressure inside the anode mud collector (1) and the extraction generated in the suction nozzle (14).
