Abstract: A pump apparatus includes a gear pump assembly interposed between top and bottom drive gear assemblies, and coupler assemblies interposed between a bottom of the top drive gear assembly and a top of the gear pump assembly, and between a top of the bottom drive gear assembly and a bottom of the gear pump assembly. The drive assemblies rotate a pre-feed auger. A cyclone screen located within a cyclone housing is positioned over a shaft of the pre-feed auger and interposed between a blade of the pre-feed auger and the bottom drive gear assembly. An intake housing is positioned over the blade of the pre-feed auger, and regulates fluid intake into the pump. As fluid is taken into the pump, it is caused to spin by the action of the auger. This causes solids to be separated from the fluid and to be expelled through exhaust ports in the pump apparatus. As a result, fewer solids are permitted to travel northward with the pumped fluid, thereby helping to protect the components of the pump.

Abstract: A garnet settling/filtration system for use with a plurality of machine tools such as a water jet cutting machine is described. The garnet settling/filtration system comprises a settling tank, which utilizes a removable, disposable settling weir, which is received therein. The settling weir drops into the settling tank and provides an over-under flow system through which the garnet slurry must travel. As the flow of the slurry travels over and under the incorporated series of baffles, the garnet particulate settles out on the bottom of the liner. Once the liner has reached its maximum holding capacity, a series of incorporated, reinforced removal loops located near the top of the liner allow for the easy and quick removal of the liner and the settled-out particulate from the settling tank. The liner can then be discarded and a new one replaced in a matter of minutes, thereby reducing downtime of the machine.

Abstract: The present invention relates to small vehicles such as lawn and garden tractors and more specifically to an oil filter assembly used with the transmissions of such vehicles. The filter assembly is housed within the transmission case to reduce mounting brackets outside the case and minimize the likelihood of insufficient oil supply to the filter, pump and hydraulic system functions. The replaceable oil filter assembly is comprised of a filtering element, a strainer element and a by-pass valve. The by-pass valve is housed within the strainer element and is adapted to direct oil flow through the strainer element, but not the filter element when the oil viscosity is high and only through the filter element when the oil viscosity is low. In this way, the parasitic horsepower loss caused by routing oil through the strainer element at all times is eliminated.

Abstract: Methods and apparatus for removing sediment from a liquid are provided. Pulses of pressurized air are directed into a conduit having an inlet disposed within a first liquid-containing vessel adjacent to (or within) the sediment to cause a slurry of liquid and sediment to flow through the conduit into a second vessel elevated above the first vessel. The slurry of liquid and sediment is allowed to drain from the second vessel into a third vessel that is positioned at an elevation lower than the second vessel. Liquid is drained from the third vessel (to another vessel or elsewhere) as sediment accumulates within the third vessel. The third vessel may be removed when accumulation of sediment therewithin reaches a predetermined amount. The accumulated sediment within the third vessel is removed and the third vessel is returned to service, or another empty vessel may be substituted therefor.

Preferably, the filter elements are cylindrical, pleated elements composed of a technical grade filter paper. In the preferred embodiment, a pressure-operated release valve is provided in conjunction with the inner filter, such that when a predetermined pressure is reached due to the entrapment of contaminants by the inner filter, the valve opens to allow the fluid to be filtered to flow through the outer filter.

Abstract: The invention relates to a multi-layer filter element. The invention provides a main filter layer which preferably consists of a melt-blown fleece and has an absolute filtration capability. A paper layer (2) on the clean side supports the filter element and does not contribute to the filtering of the fluid to be filtered. Said layer can therefore have a macropore structure, thereby allowing a low flow resistance. A layer (3)on the clean side which preferably also consists of paper serves to pre-filter the fluid and to protect and support the main filter layer. The inventive design of the multi-layer filter material provides a means for economically producing filter elements, especially filter cartridges which are folded in the shape of a star, since no trellis protective layers are necessary. The invention also facilitates an improved thermal disposability of the proposed filter cartridge.

Abstract: The automotive coolant filter was devised as a result of the inventor servicing an automotive cooling system and witnessing the evidence of contaminants depositing on cooling system surfaces. The inventor reasoned that other vital engine fluids such as motor oil and transmission fluid are filtered, wouldn't the coolant benefit also from filtration? Of course! By the simple filtration of circulating engine coolant through a paper or a fiber corrugated element, the majority of transient contaminants will be trapped. This in turn will extend the life of anti-freeze coolant as well as vital engine cooling system components.
