Abstract: A modular filter element that has a first elongate hollow body and a second elongate hollow, where a female portion extends axially into a wall of one of the elongate hollow bodies and a male portion extends axially from the other elongate hollow body into the female portion to connect the first elongate hollow body to the second elongate hollow body is disclosed.

Abstract: The invention relates to a ceramic modular filter element comprising a first elongate hollow body, a second elongate body and a sleeve for coupling the first elongate body to the second elongate body, wherein the first elongate hollow body comprises a frustoconical section, the second elongate hollow body is configured to receive the frustoconical section of the first elongate hollow body and the sleeve comprises projections for engaging with a surface of the first elongate hollow body and/or the second elongate hollow body.

Abstract: The present invention relates to a modular ceramic filter element comprising two or more elongate hollow bodies, wherein the elongate hollow bodies are formed to define twist-lock connection means for joining adjacent elongate hollow bodies together.

Abstract: The present invention relates to a modular filter element comprising a first elongate hollow body, a second elongate hollow body and connection means for connecting the first elongate hollow body to the second elongate hollow body, wherein the connection means comprises a connection member that extends into a lower wall of the first elongate hollow body and into the upper wall of the second elongate hollow body to provide a gas-tight seal between the first elongate hollow body and the second elongate hollow body.

Abstract: A filter element comprises a pleated filter (10), one end of which is received in an end cap (11), which is made up of a unitary molding comprising an end part (21) of a harder plastics material, and a lower part (22) of a softer plastics material, the plastics being compatible or of the same composition, differing only in hardness. A groove (24) engages with a support plate (14), the groove being formed in the softer material abutting the harder material so that the latter forms one face of the groove. A perforated support sleeve (29) can be inserted by dropping into the filter, and an end cap (12) at the other end of the filter either closes the end or is adapted for connection to a further similar filter.

Abstract: A filter element comprises a top frame member, a bottom frame member and a pleated filter assembly received in respective channel sectioned formers comprised by said top and bottom frame members. The formers are integrally bonded with a polyurethane resin core formed in the formers. A mould may include a core member or projections which maintain air passages during moulding, and serve to locate the pleats of the filter element in relation to the air passages.

Abstract: A clipper seam for joining the ends of a belt, are connected by interdigitated staples which are looped about a pintle and provide barbs on their remote ends to penetrate into the material of the belt. Each end is covered by an edge strip of vinyl by radio frequency welding, and a flap is attached to one end on the low pressure side of the belt by a portion, and folded over to cover the seam on the low pressure side by means of a flap which extends beyond the seam area of the other end. A central area to each side of the seam is impregnated with polyurethane to resist abrasion which tends to concentrate in this area.

Abstract: A fluidised bed filter comprises a drying pan, and a filter assembly having a membrane over the pan, and a plurality of openings in the membrane. A filter bag is secured to each aperture by means of a clamping ring attached to the rim of the respective aperture, and cooperating with a clamping band within the cuff of the bag. The material of the bag is clamped between the ring and the band. The ring is covered in a cloth strip, which is folded over to produce a flap, which is stitched between the layers of a double fabric forming the membrane. The band is retained in a tunnel formed by a fold in a double fabric forming the filter bag by stitching.

Abstract: A ceramic filter element is formed from a flocculated slurry predominantly containing inorganic fibres, of 100-150 ?m length and 1-5 ?m thickness. The slurry also contains inorganic yarn in lengths of from 10 mm or greater, e.g. 10-150 mm and thickness 0.1-0.5 mm diameter. The slurry is formed in water with colloidal silica and starch added to flocculate the slurry. The flocculated slurry is then injected to a mould comprising an appropriately shaped mesh form, and water removed by vacuum, and the filter thus formed dried in an oven for 8-12 hours at 120° C. The addition of yarns, which may be glass or alumina mono or multifilament yarns, increases the shock resistance of the ceramic filter element produced.

Abstract: A scavenging filter includes a volume containing activated beads or fiber particles of a scavenging material housed in a removable housing in a cartridge filter body having an axial inlet extending to a space below a permeable false bottom, the fluid permeating upwards through the material, and cleaned liquor leaving via an annular space surrounding the chamber.

Abstract: A phase-separation member comprises a porous substrate (11) containing void spaces, a microporous polymer material (14) which at least partially impregnates the porous substrate by entering into the void spaces, and a layer of a fluoropolymer applied to the outer face of the coagulated polymer material so that the layer (16) of fluoropolymer material remains predominantly at the surface.

Abstract: A filtration apparatus comprises a plurality of filtration sections such as (12, 13), each covered on both opposed faces by a filter cloth (14). Each filter cloth (14) is formed with a compressible edge bead (26) which is received in a corresponding groove (22-25) in a member (20) which extends between the sections (12, 13). The grooves each have an orifice for reception of the edge beads which is less than the diameter of the groove. Member (20) has a hollow core (21) to receive a sector dividing stem (17) to pass along and reinforce the member (20).
