    Abstract: Filters having a high accuracy, small pressure loss, and long filtration life compared with conventional filters are provided. The filters are composed of non-woven fibrous agglomerates and are constructed in such a way that at least two layers of a non-woven fibrous agglomerate of a pre-filtration layer and a precision filtration layer are disposed therein; the pre-filtration layer is constructed in such a way that the diameter of the fibers in the pre-filtration layer becomes gradually smaller toward the direction of filtration; and at least 10% by weight of the fibers in the precision filtration layer are fibers having a diameter smaller than that of the fibers having a smallest diameter in the pre-filtration layer.

    Abstract: A new non-woven depth filter element is formed in a continuous process whereby a mass of very fine diameter polymer filaments overlaid by mass of larger diameter polymer filaments are continuously accumulated on a spinning mandrel and advanced along and off of the mandrel by a press roller. An inner cylindrical surface of the cumulative filament mass forming the depth filter element is calendered, which facilitates insertion of a core member.

    Abstract: A method for preventing damage to valve faces and valve seat faces and also for preventing partial gas escape, which is mainly caused by solid particles generated by the reaction between incomplete combustion materials produced during engine operation and additive agents included in lubricant oils as well as by adherence of metal dust on the faces by filtering out selected particles.The solid particles are produced by the reaction of carbon as an incomplete combustion material in an engine with calcium, zinc, phosphorus, magnesium and so on which are included in the additives of the lubricant oils as well as with solid impurities generated by incombustibles included in fuel, and also with metal dust. Particles and impurities bigger than 1 .mu.m are removed by filter device composed of many piled thin papers, while the same smaller than 1 .mu.m are retained in the lubricant oil. The valve face and the valve seat face surfaces are maintained clean and smooth.

    Abstract: This invention pertains to a fluid filter apparatus and more particularly to an improved fluid filter apparatus in which a plurality of disc-like filter elements or pads is preferably mounted on a perforated tubing, although, it can work without the tubing. Each filter element is a disc-like member having a hole cut in the center and is made of a filtering type material such as fiberglass, paper or felt. Each element is cut in a pattern such as a square, triangle or hexagon whose sides are straight or curvilinear which can be cut without waste. Adjacent stacked disc filter elements are orientated such that the configuration of two adjacent filter elements does not coincide. For example, in regard to a square type configuration filter element, adjacent elements are preferably rotated 45.degree. with respect to each other from their aligned position.

    Abstract: A fluid filter and method for its manufacture in which an air laid batt is formed consisting of a randomly arrayed mixture of thermoplastic fibers and fibers which are not thermoplastic. The batt is cut into sections and is formed into cup-shaped articles in a heated mold. Accordingly, depending upon the degree of heat and pressure applied, the articles can be made of varying densities, to thereby provide articles of larger or smaller permeability and stiffness. The articles are then nested together to form a fluid filter in which fluid flows through the article of lowest density to remove the larger particles entrained in the fluid first, and then flows through articles of progressively higher density to remove progressively smaller particles. At least some of the particles have been heated and/or compressed sufficiently to be structurally self-supporting, thereby providing a filter article which does not need metallic centertube supports, etc., for structural rigidity.

    Abstract: An elongated upstanding hollow casing is provided including an upper end water outlet and a lower end combined sand and water outlet. The casing includes a mid-height laterally outwardly opening water inlet and a central upstanding tube is disposed within the casing. The tube includes a capped lower end and its upper end is in sealed communication with the upper end water outlet. The central tube includes circumferentially and longitudinally spaced apertures formed therein intermediate the capped lower end and the upper water outlet and a thick-walled tubular body is disposed about the apertured tube. The thick-walled tubular body is constructed of porous filter material such as foam rubber and the lower end sand and water outlet includes a valve assembly operatively associated therewith for selectively opening and closing the sand and water outlet. The tubular body is fitted tightly about the apertured portions of the central tube and a protective bank extends at least substantially entirely about that portion of the tubular body with which the water inlet is registered.

    Abstract: Filters self-cleaning by hydrocyclonic action are described, in which one end of the filter housing is mounted at a higher elevation than its opposite end, the filter housing having at its lower end a chamber for accumulating dirt particles washed from the outer surface of the filter body and a discharge port for purging the chamber. Several described embodiments include an auxiliary dirt-sensing filter within the latter chamber to receive on one side dirt particles accumulated in the chamber, its opposite side being connected to a source of lower pressure to produce a fluid flow through the auxiliary filter which flow is sensed to automatically open a valve to discharge the dirt particles accumulated in the chamber. Also described is an embodiment including a pump having a rotor disposed in the filter housing such that the hydrocyclonicly flowing water also drives the pump.
