1,066,546. Filtering apparatus. UNION TANK CAR CO. May 11, 1964 [May 21, 1963], No. 19576/64. Headings B1D and BIT. In a filter housing (Fig. 1, not shown) which is divided by a tube plate 26 into an inlet space (22) and a filtrate space (24), a plurality of hollow filter elements 30 being supported in the inlet space, the lower end of each element seals on a short tubular seat 40, extending through plate 26 and a fastening means 52 extends through the element with its lower end engaging the lower edge of tube 40 and its upper end carrying a spring 58 which urges the element downwards. In Figs. 1-5 the fastening means comprises a sinuous rod with a hook 52c to engage tube 40. In Figs. 6-8 (not shown), the fastening means comprises a V sectioned channel (120b) which engages the interior of the element and a lower cross piece (124) which is pushed axially through an opening in the lower end of the tubular seat and rotated to hold the element in place. The fastening means include upper sealing rings 62, compressed by the springs, and spacing flanges 60. Flanges 60 of adjacent elements engage (Fig. 2, not shown) and additional spacing bars (100, 104) may connect the upper ends of means 52. The filter housing comprises a vent (36) and a manhole 34. Prior to fitting an element on a tube 40, as illustrated in Fig. 5, a positioning means 66 is fitted into the lower end of the element, means 66 being compressible by virtue of an axial slot and serving to locate within tube 40 to prevent lateral movement of the element. Filter element 30 may be of nylon thread, wound to form a multi-layer element.

1,000,263. Filters for liquids. BENDIX CORPORATION. June 19, 1962 [Nov. 24, 1961], No. 23616/62. Heading B1D. In filtering apparatus comprising a tank 10, Fig. 1, containing a plurality of filter units 22, each unit includes a perforated tube 32, Fig. 2, supporting an edge-type filter element 30 which is formed by a stack of annular discs, or edgewound ribbon, made of fibrous or non-fibrous material, e.g. paper or cellulose, the element being initially compressed by liquid pressure and a spring 34 acting upon a plate 36 which has resilient prongs 38 for engagement with projections 40 whereby it is subsequently retained in a permanent position, Fig. 3 (not shown), in accordance with the maximum rate of flow of liquid through the unit so as to compress the filter element by a corresponding constant amount. Projections 40 may be in the form of separate rings or a helix, Fig. 4 (not shown). The end 42 of tube 32 has a sealing ring 44 and engages with a hole in a partition 16 which is situated below an inlet port 12 in tank 10. Liquid discharged from the interior of each filter unit leaves the apparatus through a port 14. A plate 24 retains the units in their mounted positions. Specifications 648,466 and 922,322 are referred to.
Abstract:
A filter system includes a housing and a plurality of filter elements disposed in the housing. The plurality of filter elements includes one or more filter elements of a first filter element type and including one or more filter elements of a second filter element type. The system also includes a receptacle plate in the housing, the receptacle plate has at least two different mating elements for attaching filter elements thereto. The receptacle plate includes one or more first mating elements configured to mate with filter elements of the first type and one or more second mating elements configured to mate with filter elements of the second type.
Abstract:
The invention relates to a device (10) for separating a heterogeneous mixture of matter into at least one retentate and one filtrate, comprising a housing (12) which is subdivided into a chamber for the heterogeneous mixture (20) of matter having at least one feed (14) and a filtrate chamber (21) having at least one outlet (16), a filter unit (22) which comprises at least one filter element (24), wherein the filter unit (22) is arranged in the chamber for the heterogeneous mixture (20) of matter, and a rinsing system (46, 47, 50, 50′) for cleaning the filter unit (22), wherein the rinsing system (46, 47, 50, 50′) has at least one rinsing port (46, 47) which is constructed so as to introduce a stream, oriented tangentially to the shell surface (54), of a first washing medium into the chamber for the heterogeneous mixture (20) of matter. The invention further relates to a method for cleaning a filter unit.
Abstract:
A device for filtering ballast water which performs filtering by installing a filter element having a conical shape in a concentric circle direction inside the device for filtering ballast water that accommodates a filter portion, and introducing ballast water from a lower end of the device for filtering and passing same through the filter element inside the device for filtering, and for discharging backwash water containing foreign substances that are inside a filter by way of differential pressure, which is created by a driving portion communicating with a filter element by rotating a suction portion that is located on a lower end of the device for filtering. Particularly, the present invention relates to a high-efficiency candle-type device for filtering ballast water having a high-density filter structure, wherein the driving portion is positioned on a lower portion of a housing so that more filter elements can be accommodated inside the housing.
Abstract:
A housing (1) for the filtration of liquid media, comprising at least one filter candle (2), which has a fluid-tight transition region (10) of a lower annular end cap (6, 6′) with central outlet (7) to a fluid-permeable outer casing (9) and has a tubular adapter (8, 8′) connected to the end cap (6, 6′), and further comprising a housing top part (3) and a housing bottom part (4) having a housing bottom (5), which latter exhibits at least one cylindrical opening (11) for the reception of the adapter (8, 8′) and separates a non-filtrate chamber (14) surrounding the outer casing (9) of the filter candle (2) from a filtrate chamber (16) connected to the central outlet (7), at least a first seal (18) being provided between the cylindrical opening (11) and the filter candle (2), which seal forms a barrier to the filtrate chamber (16), characterized in that the fluid-tight transition region (10) is received in an end cap receiving region (12) of the cylindrical opening (11) and at least terminates with the base surface (13) of the housing bottom (5), which base surface (13) faces the non-filtrate chamber (14).
