Abstract: A filter for filtering a fluid, such as lubricating oil for an engine, has a full flow filter element and a bypass filter element stacked on the full flow filter element. A flow-deflecting element is disposed between the full flow filter element and bypass filter element to provide a spinning motion to oil flowing from the bypass element as that oil joins oil which is passed through the full flow filter element. The spinning motion of the oil from the bypass filter element encourages mixing of the oil from the bypass filter element with the oil filtered by the full filter element. During operation of the engine this arrangement tends to provide cleaner lubricating oil and therefore reduces engine wear while increasing the time interval between scheduled maintenance.

Abstract: An improved fuel filter cartridge can be used with a header of a conventional fuel filter assembly. The cartridge has a water coalescing sock filter enclosed within a housing and a generally conically shaped water separating baffle with a spiralling rim and an outer barrier at the lower periphery of the baffle. As water droplets coalesce and fall off the bottom end of the sock filter, they are intercepted by the water baffle and coalesce on the radially inward side of the downwardly spiralling rim and the radially inward side of the outer barrier. As the water droplets spiral outwardly toward the outer barrier, they agglomerate. The water, thus separated and routed away from the fuel stream, exits the water baffle at an outlet of the outer barrier and falls to the bottom of the filter cartridge under the influence of gravity.

Abstract: A grease recovery system includes a basin with an inlet port to connect the system to a waste disposal network, e.g., a sink in a restaurant, and to an outlet port for draining substantially grease-free water into a sewer network. A grease outlet port provides for recovering grease from the system. The basin holds waste water to a level corresponding to the height of the outlet port above a floor of the basin. The inlet port is above that level so that incoming waste water drains into the basin. An inlet baffle is arranged within the basin and adjacent to the inlet port to force waste water entering the inlet port downwards toward the floor. A first blocking baffle, mounted to the floor, reduces waste water flow along the floor after the waste water passes through the inlet baffle, so that grease rises to the water level downstream of the inlet baffle. A motorized belt sub-system is mounted within the basin to rotate a belt which attracts grease to the belt's surface and along the water level.

Abstract: A system for removing particulates, formed as metal is machined, from coog and lubricating fluid. The system has a tank filled with fluid. The bottom of the tank slopes forward. The tank receives contaminated fluid at its top rear. The contaminants are swarf (chips removed from the workpiece) and fines (which come both from the workpiece and the grinder, borer, or drill). After the swarf is removed from the contaminated fluid by a magnetic filter, only fines remain. The fluid contaminated with fines flows from back to front in the tank, passing under a baffle projecting vertically downward from the top of the tank. A whoosh plate causes the fines to settle out into the tank, while uncontaminated fluid flows over the whoosh plate and is reused. The fines collect at the tank's bottom, from where they are pumped out and mixed with the magnetically-removed swarf for removal.

Abstract: A fuel/contaminant separator (10) designed to separate water and contaminants out of fuels used for products for combustion. The contaminated fuel (12) enters the fuel/contaminant separator (10) via the inlet pipe (14) located in the upper portion of the fuel/contaminant separator (10). A curved nozzle assembly (16) located at the periphery of the fuel/contaminant separator (10) cause a centrifugal effect to take place making separation similar to that achieved by elaborate mechanical centrifuges.

The lighter fuel particles remain in suspension and flow up the center of the fuel/contaminant separator (10) to the outlet pipe (30).
