  • Patent number: 9795905
    Abstract: An apparatus for filtering water has an interface and a filtration/purification canister removably mountable thereon. Connecting the canister to the interface automatically opens a check valve in the interface to permit water to flow from the interface into and through the canister, and then back to and through the interface to an outlet port. Disconnecting the canister from the interface automatically closes the check valve, stopping the flow of water. An end cap may be substituted for the canister to permit fluid to flow through the interface when the canister is not mounted on the interface. The outlet port may be directly connected to an appliance that uses water, to eliminate possible contamination that may occur when water is brought indirectly form the outlet port to the appliance instead. A flapper valve is provided in the canister to prevent back flow of fluid from the inlet port of the canister when the canister is not mounted on the interface.

  • Patent number: 8318011
    Abstract: A portable water disinfecting and purification apparatus comprising a first chamber into which water to be purified may be drawn by suction or negative pressure, a second chamber into which the water from the first chamber can be forced by a pumping action or positive pressure, whereby the water is initially passed across a pre-filter secured over the inlet to the first chamber and having a very small pore size and an inner cavity in which a disinfecting agent is place to filters most contaminants before the water is drawn into said filtering device, and once in the first holding chamber the water is isolated and may be further treated with a disinfectant agent, and then is passed though at least additional filtering substance including an activated carbon or nano-filter.

  • Patent number: 8313656
    Abstract: A variable wash flow filter assembly includes guide that is operable to guide a wash velocity control cone between a minimal position and a maximum position. The guide defines at least one activation deltaP window downstream of a conical gap between the wash velocity control cone and a frusto-conical wash filter. The fuel flow through the conical gap and the activation deltaP window is operable to position the wash velocity control cone between the minimal position and maximum position to selectively split a fuel flow through an inlet into a burn flow through a thru flow port and a filtered flow thru the frusto-conical wash filter and filtered flow port.

  • Patent number: 8282789
    Abstract: Extraction apparatus and method for obtaining essential oils, essence, and pigments from odorous raw materials (e.g., plant materials and Chinese medicinal herbs) by microwave radiation heating have advantages of easy operation, higher extracting temperature and efficiency. The microwave chamber has a power level of 100 W to 1,500 W and its microwave radiation has a frequency at 915 MHz or 2,450 MHz. The extraction process can be performed without any preheating necessary. A condenser is operated at temperatures between ?20° C. and 15° C. for cooling the gas flowing out of the extraction cartridges. Because both volatile fragrant compounds and pigments of the odorous raw materials can be extracted successfully by the top-down extraction fashion, the extracted essence is colorful. Since the extraction process by microwave heating is free from adding any organic solvent and/or any artificial chemical compound, the extraction apparatus and method are environmentally friendly.

  • Patent number: 8282880
    Abstract: A bottle, a system and a method sterilize a liquid. The bottle has an interior to hold the liquid and an ultraviolet light emitting lamp that extends into the interior. A cord may be attached to the bottle so that pulling the cord may power the ultraviolet light emitting lamp and/or charge a battery used to power the ultraviolet light emitting lamp. The bottle may have a status light that indicates that the ultraviolet light emitting lamp may have an amount of power equal to or greater than a threshold value, such as, for example, an amount of power necessary for the ultraviolet light emitting lamp to operate for ninety seconds. The bottle may have a removable lid located opposite to the ultraviolet light emitting lamp.

  • Patent number: 8157987
    Abstract: A multiple filter controller for monitoring two or more filters to detect when any of the filters is malfunctioning and for polishing a fluid, wherein the multiple filter controller comprises a first filter; a second filter; an inlet valve, wherein the inlet valve provides the fluid to the first filter and to the second filter wherein the fluid originates from a supply station; an outlet valve, wherein the outlet valve provides an outlet source for the fluid from the first filter and from the second filter; a bleed valve located downstream of the outlet valve; and a first conduit in communication with the bleed valve and with the supply station, wherein the fluid passes into the multiple filter controller via the inlet valve, and wherein the fluid is returned to the supply station by feeding the fluid into the first conduit via the bleed valve.

  • Publication number: 20110315630
    Abstract: Simplified liquid-solid and liquid-liquid separations after centrifugal extraction are used to extract a target substance from a substance mixture into a solvent. An extraction container has a closed-end cylindrical shape, and is rotated around a central axis by an extractor rotor driven by a motor. The extraction container includes: an opening provided in a bottom portion thereof; and a valve (valve ball) provided at the opening, and opened or closed by a pressure difference between above and below the valve. In extraction, a substance mixture and a solvent are put into the extraction container. The extraction container is repeatedly subjected to normal rotation, pausing, reverse rotation, and pausing to thereby extract a target substance from the substance mixture into the solvent and to separate the liquids into upper and lower layers.

  • Patent number: 8021541
    Abstract: The present invention relates to an automotive engine cooling system and the ability to filter contaminates from the cooling system liquid thus slowing down metal erosion of internal cooling system components. The present invention also allows the user to visually see the condition of the filtering device and the condition of the cooling system liquid. If the filtering device should plug or clog, a by-pass system is in place to allow the cooling system liquid to continue circulation not affecting the vehicle's engine temperature.

  • Patent number: 7955500
    Abstract: An assembly is disclosed that includes a centerpost assembly and a fluid filter cartridge. The centerpost assembly includes a main body having an inlet flow opening, an open interior, and a radial flange. An interior shelf is positioned proximate the inlet flow opening of the main body. The interior shelf includes an interior flow opening. A check valve ball is movably positioned on the interior shelf to move between the inlet flow opening and the interior flow opening. A spring-loaded end cap is movably connected to an upper end of the main body and is configured to move between a compressed state and an uncompressed state. A blocking pin extends from a lower surface of the end cap. When the end cap is in the compressed state, the blocking pin prevents the check valve ball from blocking a flow of fluid from flowing through the interior flow opening.

  • Publication number: 20110042282
    Abstract: A pressure-controlled liquid supply system uses a pump control device to switch a pump on and off in response to a pressure level in the pumped liquid. The pump control device minimizes short cycling of the pump by preventing shut off of the pump while a flow is present through the pump control device and by delaying the shut off of the pump. The pump control device also avoids a significant drop in the output pressure by creating a reduced pressure zone, which provides the switch pressure used to switch the pump off.
