  • Patent number: 9428405
    Abstract: A valve (16) comprising a housing (30), a valve filter media (34) and an actuator (48). The housing (30) defines a chamber (32) having an inlet (44) and outlet (48). The media (34) is positioned within the chamber (30) such that liquids flowing between the inlet (44) and outlet (48) pass through the media (34). The valve filter media (34) is formed of a material which can absorb hydrocarbons, causing the media (34) to change its material properties thereby restricting the flow of liquids through the valve (16) and increasing the pressure differential across the media (34). The actuator (48) has at least a portion positioned within the housing chamber (32). If the pressure differential across the media (34) exceeds a predetermined threshold, the media (34) bears against the actuator (48) causing the actuator (48) to restrict the flow of liquids through the valve (16).

  • Patent number: 8871101
    Abstract: First and second liquids are separated from mixtures thereof in a holding tank that holds quantities of the two liquids after they have been separated and a quantity of the mixture that has not been separated. A first transfer conduit receives a pressurized mixture of the first and second liquids which is discharged into the holding tank. A venturi passageway is located in the first transfer conduit. A liquid conductor has an entry opening positioned so that at least a portion of the entry opening is located within the quantity of the mixture that is held in the holding tank and an exit opening that is in fluid communication with the venturi passageway. The increase in the velocity of the pressurized mixture flowing through the venturi passageway and the accompanying reduced pressure causes the mixture held in the holding tank to flow through the liquid conductor into the venturi passageway.

    Abstract: A filter apparatus, particularly for filtering coolant/lubricant from a machining, including a filter tank having an inlet for the liquid to be filtered, an outlet for the filtered liquid and a belt of filter medium adapted to circulate within the filter tank and having a top side and a bottom side. The liquid to be filtered is introduced below the bottom side and is discharged between the top side and the bottom side. The filter material of the bottom side separates the unfiltered liquid from the filtered liquid and prevents floating particles in the liquid from reaching the outlet for the filtered liquid.

  • Patent number: 7740757
    Abstract: An exemplary apparatus (20), for removing pollutants atop a body of coolant, includes a filter (21), a pollutant removing structure (22), and a pump (23). The filter includes a housing (210), and a filtering unit (211) positioned in the housing for removing the pollutants from the coolant. The filtering unit is separated into a first cavity (2112) and a second cavity (2113) by a partition sheet (213). The partition sheet is spaced apart from a bottom surface of the housing to define a communicating gap (2131) for the first cavity and the second cavity to communicate with each other. The pollutant removing structure is positioned on the filter. The pollutant removing structure includes a removing member (221) for removing the pollutants out of the filter. The pump is configured for pumping the coolant into the first cavity of the filter.

  • Patent number: 7713425
    Abstract: An oil management system and oil filter utilized in association with an internal combustion engine. The oil filter comprises high-efficiency filtration media for filtering engine oil associated with the internal combustion engine. At least one type of time release additive can be impregnated into the filtration media, wherein the time release additives are automatically released into the engine oil filter from filtration media in order to replenish additives already present in the engine oil. Additionally, a sensor module can be provided that monitors oil quality and oil filter efficiency through detecting one or more attributes of the engine oil filtered through the filtration media of oil filter in order to efficiently conserve and manage the oil and reduce the interval of oil changes thereof by extending the life of the engine oil through the replenishment of the additives present in the engine oil and higher filtration effectiveness of the filter.

    Abstract: The portable and autonomous desalination system is an autonomous reverse osmosis (RO) desalination system utilizing power from a combination of electricity generation and storage sources that include a photovoltaic (PV) unit, a vertical-axis wind turbine (VAWT) unit, and an electricity storage unit. Electric power from PV, VAWT or storage units or a combination of these units is provided, depending upon the availability of sunlight or wind, or for night operation for water desalination using the reverse-osmosis process. The unit is portable, environmentally friendly, self-sufficient and self-sustaining in terms of supplying the electricity and fresh drinking water needs of the typical household. Multiple PV-VAWT-RO desalination units are combined together to provide fresh, clean water and electricity for communities of various sizes. A small-size, straight-bladed vertical axis wind turbine runs at very low wind speeds for urban operation.
