    Abstract: A filter apparatus is provided comprising a number of cylindrical candle filters, each of which contains a displacement body forming a space of uniform width between itself and the candle filter. The filter material of the candle filter is supported by a cylindrical supporting body which has passages through which a plastic melt to be filtered can flow. A number of filter apparatuses can be arranged on concentric circles on a cylindrical filter housing so as to minimize the dwelling time of the plastic melt flow through the filters and to minimize the pressure loss over the length of the filters.

    Abstract: A filter system comprising a tank and a filter assembly removably mounted therein. The filter assembly includes a plurality of filter tubes in fluid communication with a plenum chamber on the bottom thereof. The plenum chamber is open on its bottom, and rests on the bottom of the filter tank. Suitable seals maintain the fluid integrity of the plenum chamber against the bottom of the tank. The filtrate leaves the plenum chamber through an outlet port in the bottom of the tank.The inlet port is also in the bottom of the tank, and the fluid to be filtered passes upwardly through a channel formed in the center of the plenum chamber. The top of the tank is sealed by a U-shaped gasket, with the cover of the tank resting on the gasket. No auxiliary flanges are needed to provide a top seal. The cover of the tank is raised by a lifting mechanism, and is rotatable away from the top of the tank to permit access to the tank. When the cover is to be returned to its closing position, a keying mechanism automatically seats the cover in the proper position.

    Abstract: Filtering equipment has an inlet chamber which houses removable filtering cylindrical cartridges. The circular end surfaces of each cartridge are seated by annular seats, one on a rigid divider which separates the inlet chamber from an oulet, and the other associated with a removable rigid cover which is spaced a predetermined distance from the divider when the cover is fixedly mounted to close the inlet chamber. These two seats serve as seals for the ends of the associated filter cartridge, and at least the latter annular seat is flexibly yieldable in the axial direction of the cartridge. The normal combined axial dimension of the cartridge and its two seats, when not under axial compression, is greater than the normal distance between the divider and the cover, so that, when the cover is clamped down, in its assembled position on the inlet chamber, the flexible annular seat member is distorted, to form a tight seal against the cartridge and the cover. Each cartridge is positioned by a pair of centering posts, one of which is fixed in the cover and passes through the middle of one annular seat, and projects into the central hollow of the cylindrical cartridge; and the other of which is secured in the rigid divider, passes through the associated annular seat, and extends into the central hollow of the cylindrical cartridge.

    Abstract: 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.

    Abstract: 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.
