  • Patent number: 11897788
    Abstract: A water filter system that includes a base that receives water from a faucet, where the base includes a bottom support and a vertical support transversely extending from the bottom support. The vertical support includes a visual light display having visual indicators that indicate different parameters of the filter system. A filter cartridge is seated in the base, and defines a first chamber having at least one filter element, and a second chamber in fluid communication with the first chamber. An enhancement cartridge is removably inserted in the second chamber of the filter cartridge and includes an enhancement material for adding minerals to the water. A cover having an opening is configured to slidingly engage the vertical support of the base so that the visual light display is positioned within the opening of the cover and visible to a user.

  • Patent number: 8888998
    Abstract: A head for a water filter system having a filter element including a three-way valve member movable between a first position, a second position, and a third position. When the valve member is in the first position, incoming water is directed to the filter element to remove sediment and impurities from the water. When the valve member is in the second position, the incoming water is blocked from passing through the filter element and the valve member. Lastly, when the valve member is in the third position, the incoming water passes through the valve member and not the filter element so that the filter element can be removed and replaced without interrupting the incoming water flow.

  • Patent number: 7837876
    Abstract: A filter cartridge including a housing having a water inlet and outlet, a valve disposed in the housing and defining transversally aligned inlet and outlet passageways, and having a first key formation that vertically depends from the valve, a cartridge having transversely separated inlet and outlet ports transversely aligned relative to a longitudinal axis of the cartridge, each of the ports engageable in a corresponding one of the passageways, and a complementary key formation for engaging the first key formation for ensuring proper engagement of the ports in the passageways where the ports and the key formation project from a common plane. The valve is rotatable in the housing between an open position in which feed water passes through the inlet passageway and into the cartridge, and treated water flows to the outlet passageway, and a closed position in which water is prevented from flowing to and from the valve.

  • Publication number: 20070284296
    Abstract: A filter assembly includes a head housing having a water inlet and a water outlet, and a valve disposed in the housing and defining inlet and outlet passageways, and having a first key formation. A cartridge is provided having separate inlet and outlet ports each engageable in a corresponding one of the passageways, and a complementary key formation for engaging the first key formation for ensuring proper engagement of the ports in the passageways. The valve is rotatable in the housing between an open position in which feed water passes through the inlet passageway and into the cartridge, and treated water flows to the outlet passageway, and a closed position in which water is prevented from flowing to and from the valve. The inlet and outlet passageways and the first key formation are generally linearly aligned.

  • Publication number: 20070126284
    Abstract: A regenerative brake of the present invention presents a hydraulic device disposed in a front hub of a bicycle wheel. The device allows the bicycle to recapture part of the kinetic energy that would otherwise be lost when braking and make use of that power either by storing it for future use or feeding it back into a power system to be used. The hydraulic device may also be stored in a rear hub of the bicycle wheel.
