A dialyzer housing manufacturing system includes a molding device configured to mold a dialyzer housing, and a tool coupled to a robotic arm and configured to retrieve the dialyzer housing from the molding device after the dialyzer housing is molded. The tool includes a frame, a first suction cup connected to a first portion of the frame, and a second suction cup connected to a second portion of the frame, the second suction cup being oriented about 70 degrees to about 110 degrees relative to the first suction cup.

A piece of substrate material is formed under heat and pressure against a cavity into a shaped substrate sheet having one or more depressions. Two substrate sheets are bonded together to form a substrate wherein the one or more depressions form one or more interior channels. The substrate, if not formed with pre-coated substrate material, is coated with a dope and quenched to form a filtering membrane. A plurality of membranes may be placed side by side to form a bundle with permeating ends of the membrane, which are open to the one or more interior channels, separated by gaps or spacers. The bundle is connected to a header to produce a module. The module can be assembled into a cassette.

Embodiments relate to apparatus for manufacturing a carbon block filter and a method for manufacturing a carbon block filter. The apparatus for manufacturing a carbon block filter according to an embodiment may include a mold having an inner space, a heater coupled to the mold to heat the mold, a material injection unit injecting a material to the mold heated by the heater, a material pressing unit pressing the material, and a filter separation unit separating a thermally treated filter from the mold heated by the heater.

The present invention relates to polymer compositions comprising at least one basic additive, and processes comprising at least one process step to obtain the polymer composition or articles comprising the polymer composition. The polymer composition generally displays an enhanced biodegradability.

Equipment for forming a tubular rod from a bundle of fibrous material comprising a mandrel constructed to form a space within the bundle of fibres; the mandrel includes a passage for delivering a treatment fluid to facilitate the formation of the fibres into a tubular structure as the fibre bundle as the bundle passes over the mandrel.

Method and related equipment for the production of filtering panels (8) made up of a filtering fabric (5) locked and tensioned inside a frame (7) consisting of two mutually coupled half frames (7a, 7b), wherein the moulding of said frame (7) of said panel (8), the unwinding of said fabric (5) from a feeding roller (4) and the tensioning of the same fabric (5) in the frame (7) are carried out, the latter being performed automatically during said moulding step. Compared to the solutions employed in the prior art, the equipment and the method of the invention offer the advantage of automating every operation for assembling the filtering panel, locking the fabric in a centered position on the frame in the making, tensioning it and cutting it out around the frame already moulded on the panel.

A faceblank (5) for a respiratory protective device or face mask hygiene product (1), where the shape of the faceblank (5) defines a number of filter openings (2, 3, 4) and which further comprises a head harness (6) or fastening for a head harness (6) and is characterised in that the filter openings (2, 3, 4) have been implemented to comprise a tongue (7), most advantageously so that the edge of each opening (2, 3, 4) is composed of a tongue. The faceblank is used with a number of replaceable filters (10) adapted in the filter openings (2, 3, 4) of the faceblank (5), each filter (10) comprising a filter part (11) and a frame (12) that encircles the filter part (11), in which frame (12) the outer edge has been implemented to comprise a groove (13)most advantageously so that the outer edge of each frame (12) consists of a groove (13)so that the filters (10) are fastenable to the filter openings (2, 3, 4) of the faceblank (5) by means of a tongue-and-groove connection, in which case the tongue (7) and groove (13) form an air-tight tongue-and-groove connection. Further independent claims directed to filters and methods for the manufacture of reinforced textile part, nonwoven fabric part or their combination part.

A filtration element has one or more rigid inserts in a housing. The inserts are covered with membranes. The element is configured to provide open feed channels beside the inserts. The membranes and inserts are potted at an edge, optionally at only part of an edge such as a corner. Permeate flows between the membrane and the insert to the potted edge. The membranes may be potted in a centrifuge.
