Abstract: A filter system in which a housing and an environmentally friendly filter cartridge are coordinated to provide ease of change of the filter cartridge and reliable operation. The cartridge contains no metal parts and is readily incinerateable. The housing is provided with a number of nulluniversalitynull features including a changeable bottom which allows the housing to operate as a fuel filter, a lubrication filter, or a hydraulic filter in different applications. The housing and cartridge are configured to provide support for the plastic elements of the cartridge to prevent crushing of the filter under normal and abnormal filter operating conditions. A key system associated with the cartridge and the housing provides assurance that the correct filter is installed for a particular application.

Abstract: An adjustable continuous filtration system; a continuous split-stream bypass filtration system; a method for controlling the proportion of a fluid recycled through a filtration system; a method for controlling the proportion of a fluid which is routed to the filter of a filtration system, and the proportion of the fluid which is discharged from the system without passing through the filter; and a method for controlling the quality of cooking fats and cooking oils. The mechanisms for controlling the proportion of fluid routed or recycled to a filter depend on the size or width of orifices in passageways conveying the fluid, including the restriction of one or more of the orifices. A needle valve beneficially provides a continuous range of variation of orifice size. If the quality of cooking fat or cooking oil discharged from the filtration system is below industry standards, the proportion of the cooking fat or cooking oil routed or recycled to the filter is increased. If the quality of the discharged cooking fat or cooking oil is appreciably above industry standards, the proportion of the cooking fat or cooking oil routed or recycled to the filter is decreased.

Abstract: A fuel pump module disposed within a vehicle fuel tank has a fuel pump therein to draw fuel from the fuel tank and deliver that fuel under pressure to the vehicle engine, and a jet pump driven by the fuel pump to lower the pressure within the module to draw fuel from the fuel tank through a filtered inlet of the module when the fuel pump is operating. When the fuel pump is not operating, such as when the vehicle is not in use, the jet pump ceases to operate and the pressure within the module returns to that of the fuel tank. When the level of fuel in the fuel tank is lower than that within the fuel pump module and the pump is turned off, a portion of the fuel within the module returns to the fuel tank, through the filtered inlet of the module thereby dislodging at least some of the contaminants trapped by the filter.

Abstract: A fluid filter assembly which is constructed and arranged to threadedly mount onto an engine block mounting base includes an enclosing outer shell, a filtering element positioned within the outer shell so as to define an annular clearance space between the outer shell and the filtering element. A nutplate is assembled to the outer shell so as to close the outer shell and provide an internally-threaded mounting portion for attachment to the engine block mounting base. The sidewall which defines the threaded mounting portion is free of any flow openings therethrough. A seal arrangement including an inner seal positioned between the nutplate and the filter element and an outer seal positioned between the engine block mounting base and the nutplate is provided as part of the fluid filter assembly. The nutplate and inner seal are designed to cooperate with each other so as to define a plurality of flow passageways extending between the nutplate and inner seal and providing a flow path from the engine block mounting base to the annular clearance space.

Abstract: A unitary nutplate for a fluid filter assembly provides a threaded mounting interface between an engine block mounting base and the remainder of the fluid filter assembly. The unitary nutplate is designed with an enlarged inside diameter in order to reduce the moment arm between the outer shell of the fluid filter assembly and the filtering element. With the enlarged inside diameter, the annular sidewall of the unitary nutplate does not include any flow passageways for the entering fluid and accordingly other flow passageways are created. In one arrangement, the nutplate has a generally cylindrical lower wall which cooperates with an inner seal which is designed with fluid flow passageways. In an alternate nutplate design, depending projections from the lower edge of the nutplate provide a series of flow passageways therebetween and the cooperating inner seal does not include flow passageways.

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.

Abstract: A method of operating a filter centrifuge or centrifugal filter in which a hydrostatic head is provided at the filtering surface so as to control liquid passage therethrough. The head may promote movement of the liquid through the filter layer or may induce reverse flow of liquid for backwashing or rinsing. In addition, a hydrostatic balance may be provided at this surface through control of the head to limit passage of the liquid through the filter layer. Preferably the head provides a suction augmenting centrifugal filtration.

Abstract: An aerobic waste material treatment system includes a hydraulic comminutor-reaction tank and a vacuum aeration tank connected by a siphon so that comminuted solids in liquid are siphoned into the vacuum tank. A recirculating pump and fluid connection are positioned between the vacuum tank and hydraulic comminutor to recirculate the mixed liquor from the vacuum tank and reaerate it by an aspirator in the recirculating line while, at the same time, discharging tangentially into the comminutor to aid in centrifugal movement for comminuting purposes. A venturi in the recirculating pump discharge line aspirates from the vacuum tank to draw the vacuum within the vacuum tank. The air for anchor in the vacuum tank is admitted from atmosphere under control of a regulating valve. An automatic back flushing filter is connected to the effluent outlet of the vacuum tank. The filter is periodically back flushed by pulsing air from the outlet side of the filter to flush accumulated material on the filter screen back into the vacuum tank. The vacuum tank may be blown down through a blow down valve in the discharge side of the recirculating pump. Automatic batch chlorination and effluent ejection units are connected to the outlet side of the automatic back flushing filter.
