Abstract:
PROBLEM TO BE SOLVED: To provide a filter device which can do disassembly work, bear a relatively high pressure, and do efficient filtration work. SOLUTION: In the filter device having a pleated filter 1 and upper and lower lids 2 and 3 which protect the upper and lower sides of the filter and in which a suction port is formed in at least one of the lids, the upper and lower lids are bonded to the upper and lower end spots of the filter respectively through an isolation film 4 by a curable plate body 5 having a prescribed thickness, a plurality of bonding projections 6 are formed attachably/detachably in the upper and lower lids, and the bonding projections are embedded/bonded in/to the curable plate body.

Abstract:
An End Cap for an Assembly Used in the Preparation of Compressed Gas An end cap for attaching to one or more filter elements and respective filter bowls is disclosed. The end cap has a tubular body formed by extrusion and this body has a series of apertures formed therein. The apertures include an end aperture for attachment to a filter bowl and another end aperture for attachment to another filter bowl or to a sealing disc. The body also has a pair of sidewall apertures to act as inlet and outlet the filter assembly. The end cap also has a plastic insert for insertion into the body, the insert having a conduit portion for directing a stream of gas from the inlet to a filter element through one of the end apertures.
Abstract:
A filter element for positioning in a filter compartment of a spa includes a plastic mesh outer cylinder and a plastic mesh inner cylinder, the inner cylinder being positioned coaxially with respect to the outer cylinder to define an annular interior chamber with a filter element of annular cross-section disposed in the chamber and having keyed landings formed on the top and bottom thereof, which respectively mate and interlock with one or more keyed landings on top and bottom caps of the filter element. The apparatus may further include a plurality of vertically disposed mesh compartments interlinked in a ring and disposed within the filter element, the compartments being filled with a selected filter medium or filter media.
Abstract:
A filter module for fluids, comprising a pleated filtering membrane (6) the surface of which separates a pre-filtration volume, upstream of the filtering membrane (6), from a post-filtration volume, downstream of the filtering membrane (6), said pleated filtering membrane (6) presenting, on its surface, pleats bounded by contiguous crests (7), said filtering membrane comprising, on the pre-filtration volume side, a conveyor (10) for causing the filtrate to flow substantially between the pleats of the pleated filtering membrane (6).
Abstract:
A filter cartridge which comprises a filter pack (3) formed by a flat filtering medium, a tubular sheath (2) with a perforated wall, surrounding the filtering pack, and two respective end caps (5) having a first disc (16) and a second disc (17) placed one on top of the other, each made from thermoplastic, with a portion of the filtering pack (3) situated along one of its edges and a portion of the sheath (2) situated along one of its edges (33) which are embedded in the second disc (17), with the first disc (16) having a peripheral rim (19) which surrounds the relevant portion of the sheath (2) and with the sheath having a shoulder (34) opposite the edge of the rim (19) of the first disc (16).
Abstract:
A method of attaching an end cap to a filter member begins with a step of providing a first plastic end cap configured to fit on an end of a filter member. The next step in the method is heating the end cap to soften an inner surface thereof. The preferred method of heating the end cap involves applying infrared heat to the cap without contacting it. The next step in the method according to the invention is contacting the filter member with the heated surface of the end cap. Preferably the end cap is pressed into place against the filter member, using an appropriate machine, and applying enough force to partially embed the end of the filter member into the molten plastic. The next step in the method involves holding the end cap in place against the filter medium until the end cap cools sufficiently for the material thereof to stiffen, causing the filter member to adhere thereto.
