Abstract

An improved cartridge-type fluid processing apparatus having a tubular housing disposed about and supporting a tubular porous element. First and second end pieces are welded to and seal first and second ends of the housing and the tubular porous element.

Claims

AMENDED CLAIMS
[received by the International Bureau on 13 May 1996 (13.05.96); new claims 29-45 added; remaining claims unchanged (4 pages)]
29. An apparatus for use in processing fluids comprising: a tubular porous element having first and second ends and interior and exterior major surfaces extending between the first and second ends; a non-perforated housing having first and second ends and a tubular portion extending between the first and second ends and disposed about the tubular porous element; a first housing end piece sealed directly to the non-perforated housing and to the tubular porous element at the respective first ends and including a first opening communicating with the interior of the non-perforated housing; and a second housing end piece sealed directly to the non-perforated housing and to the tubular porous element at the respective second ends and including a second opening communicating with the interior of the non-perforated housing.
30. The apparatus of claim 29 wherein the first and second opening are in fluid communication with the interior of the tubular porous element.
31. The apparatus of claim 30 wherein the first and second housing end pieces respectively include a third and a fourth openings in fluid communication with the exterior of the tubular porous element
32. The apparatus of claim 29 wherein the first and second opening are in fluid communication with the exterior of the tubular porous element.
33. The apparatus of claim 29 wherein the first opening is in fluid communication with the interior of the tubular porous element and the second opening is in fluid communication with the exterior of the tubular porous element.
57 34. An apparatus for use in processing fluids comprising: a tubular porous element having interior and exterior major surfaces extending between first and second ends; a non-perforated housing having a tubular portion extending between first and second ends and disposed about the tubular porous element; a first end piece sealed directly to the housing and to the tubular porous element at the respective first ends; and a second end piece, identical to the first, sealed directly to the housing and to the tubular porous element at the respective second ends.
35. An apparatus for use in processing fluids comprising: a tubular porous element including first and second ends and a plurality of longitudinally extending pleats extending between the first and second ends, each of the pleats including a pair of legs having first and second surfaces and being in a laid- over state where the first surface of each leg is in intimate contact with the first surface of an adjoining leg and the second surface of each leg is in intimate contact with the second surface of an adjoining leg over substantially the entire height of each leg and over a continuous region extending substantially between the first and second end; a housing having a tubular portion extending between first and second ends and disposed about the tubular porous element; a plurality of fluid flow grooves extending between the first and second ends and being disposed between the housing and the tubular porous element; a first end piece sealed directly to the housing and to the tubular porous element at the respective first ends; and a second end piece sealed directly to the housing and to the tubular porous element at the respective second ends.
36. The apparatus of claim 35 wherein the tubular porous element includes a first drainage material disposed between the first surfaces and a second drainage material disposed between the second surfaces.
5 8 37. The apparatus of claim 35 wherein the housing supports the tubular porous element.
38. The apparatus of claim 37 including an inlet in fluid communication with an interior surface of the tubular porous element and an outlet in fluid communication with the fluid flow grooves whereby fluid flows through the inlet, through the porous element, through the fluid flow grooves and out the outlet.
39. The apparatus of claim 38 including an annular channel disposed at the second end of the housing in fluid communication with the outlet and the fluid flow grooves whereby fluid may flow from each of the fluid flow grooves into the annular channel and then through the outlet.
40. A filter assembly comprising: a housing having at least an inlet port and an outlet port; a cylindrical filter element including filter media wherein both end surfaces of the filter media are joined to the housing by an irreversible welded joint.
41. The filter assembly of claim 40 wherein the housing includes a cylindrical wall portion and first and second end portions and wherein the inlet is disposed in the cylindrical wall portion near the first end portion and the outlet is about centrally in the second end portion.
42. The filter assembly of claim 40 wherein the housing includes a core having first and second end portions respectively joined to the first and second end portions of the housing, the core being disposed about the outlet port.
43. The filter assembly of claim 40 wherein the housing includes a vent nozzle provided in the upper portion of the housing at the position corresponding to the area in which the downstream liquid is accommodated.
5 9 44. The filter assembly of claim 40 wherein the welded joint if formed through thermal fusion.
45. A filter assembly comprising: a housing having an inlet and an outlet; a cylindrical filter element having a filter media including first and second end surfaces, an end cap, and a cage disposed about the filter media, the first end surface being joined in a the end cap via an irreversible welded/thermally fused joint and the second end surface being joined to the housing via an irreversible welded/thermally fused joint.
