Abstract: A filter product includes a filtration media combined with a multi-component frame assembly that can effectively support the filtration media in place proximal to its edges and in accordance with its desired orientation and wherein the assembly can be selectively taken apart to provide access to the filtration media by way of a releasable lock connection. Preferably, a snap-fit releasable locking system is incorporated within the frame design. The present invention is particularly applicable to filtration media comprising pleated filtration media. Such support features include rack-like media engagement elements, which elements are advantageously provided so as to preferably engage the filtration media proximal to its side and end edges from above and below to preferably compress and ensure an effective seal and support connection between the frame and the filtration media. Such a construction is further beneficial for supporting filtration media that includes a layer or other loading of particulate matter therein. The media engagement elements are spaced along the side of a support frame and a hold down frame and the side frame elements include sidewalls in combination. The sidewalls are spaced from the media engagement elements so as to support and preferable compress the filtration media inward from its side and end edges to support and effectively contain the filtration media and any particulate material therein.

Abstract: A method and apparatus are disclosed for providing a crimp seal pleated filter assembly having a two piece housing with a filter media disposed within the housing and having a plurality of alternating pleats. The apparatus includes a first and second jig for supporting the housing halves and an odd number of at least three or more movable pleat forming blades on one side of the apparatus. The odd number of blades are movable through one of the supporting jigs with blade edges opposing the other supporting jig. The odd number of blades includes an independently movable center blade and a first pair of outer blades with opposing surfaces of adjacent blades defining a first plurality of pleat forming spaces. An even number of pleat forming blades are positioned with blade edges opposing the first plurality of pleat forming spaces and are spaced apart from and in alignment with the opposing pleat forming blades. The even number of pleat forming blades includes at least a pair of center blades which project through the other supporting jig during pleat formation and define a pleat forming space in which a first center pleat is formed. The blades and the jigs are moved toward one another in a predetermined sequence for the blades to form desired pleats within a filter media and for the jigs to urge the filter housing around the pleated filter media to crimp seal and encapsulate the media within the housing.

Abstract: A filter element has a generally ring-like structure which basically comprises a plurality of generally radial sections circumferentially arranged to define a central space. Each radial section has a plurality of circumferentially zigzag pleats formed from a ribbon of a filtering sheet material. The radial sections are circumferentially connected such that radially inwardly open generally radial spaces and radially outwardly open generally radial spaces are defined. The radially inwardly open radial spaces are closed at the axially opposite ends by end walls. Fluid to be filtrated can enter the radially outwardly open radial spaces and then passes through the zigzag pleats into the radially inwardly open radial spaces and thus into the central space. The ring-like structure has many modifications.

Abstract: The filter element of the present has a plurality of wavy portions which are so arranged that a plurality of wavy portions make a generally ring like structure. In order to reduce the pressure drop when the fluid flows through the filter element, the present filter element has a special shaped radial gaps. Namely, the width of a first radial gaps, which is formed within adjacent wavy portions and which connects with an inner space formed at the center of the generally ring like structure, increases from the outer end thereof to the inner end thereof. The width of a second radial gap, which is connected with outer atmosphere, decreases from the outer end thereof to the inner end thereof. Both axial ends of the wavy portions are covered with the adhesive sheet on which adhesive layer is cladded.

Abstract: A method and apparatus for making axial-flow filters wherein a sectorial-shaped sheet of filter material having corrugations therein parallel to the curved ends thereof is made from a flat sheet of filter material in the first step, and thereafter the corrugated sheet is made into an annulus to obtain the final product. In the first step, an edge portion of a flat sheet of filter material is attached to a sectorial-shaped mold, having a mold surface defined by curved ridges and valleys parallel to the curved ends of the mold, so that the sheet is slanted up away from the mold surface from the smaller curved end of the mold. Thereafter a set of curved forming blades is moved down toward the mold to engage the sheet and to fold it successively and consecutively across the ridges of the mold and beneath the edges of the blades into the valleys of the mold to corrugate the sheet. In the second step, the corrugated sheet thus produced is made into an annulus by using a contouring belt which embraces the larger convexly curved ends of the sheet and constricts the sheet into an annulus.

Abstract: A filter assembly is provided for fitting to an aperture in the wall of an oil tank of a hydraulic system with a disposable filter canister positioned substantially within the tank. The canister comprises a shell having an end wall and a generally cylindrical side wall, an end plate attached to the shell, a tubular filter element fluid-tightly fitted between the end wall and the end plate to define an outer chamber and an inner chamber between which the only flow path is through the filter element. The end plate has a central aperture communicating with the inner chamber and surrounded by a ring of apertures communicating with the outer chamber. A filter head is fluid-tightly fitted to the outer face of the tank wall in register with the aperture. Locating means in or on the canister cooperate with support means in or on the filter head to support the canister in a predetermined axial position relative to the tank wall with its end wall and at least a major portion of its cylindrical side wall within the tank. A chamber within the filter head communicates with the ring of apertures in the end plate, and a port for connection of an oil inlet or return pipe also communicates with the filter head chamber. An opening through which the cartridge may be inserted or withdrawn is closed by means of a removable cap fluid-tightly fitted to the filter head, and the canister has an aperture in the end wall communicating with the inner chamber.

Abstract: Geometrical structures having alternate asymmetrical folds of drawable or extensible material forming two faces wherein the folds on each of the faces are substantially identical to the other folds on that face. The fold on one of the faces have a rounded profile in cross section which is somewhat wider than the profile on the other face of the structure. The structure may be produced by the rectilinear pleating of a flat sheet or of a longitudinally corrugated sheet or by the chevron pleating of a flat sheet. Such structures may be used as sandwich core materials, filtering screens, cylindrical insulating materials and filtering cartridges, by way of example.
