  • Patent number: 5316216
    Abstract: A showerhead is either wall mounted or provided with a handle connected through a flexible hose to an incoming water outlet. The showerhead has a turbine which may cause the delivery of pulses of circumferentially distributed groups of pulses of water so as to provide either fast or slow massage action. Also included is a pause mode in which flow is reduced without complete shutoff and a center spray mode which provides a concentrated spray pattern. Other modes possible are a needle spray, a combination pulse and needle spray, a combination needle spray with a body spray, just a body spray, and an oval shape spray pattern. Various water paths are defined from a flow selector through the unit to different ones of front-facing orifices as defined for the different modes. Selection is achieved by a combination of a flow director and a control plate. User access for mode selection is by way of an external circumferential control ring operatively coupled to the control plate through a control arm.

  • Patent number: 5131277
    Abstract: A reverse osmosis system includes a sediment filter which cleans feed water from a source and from which that feed water is fed to a reverse osmosis membrane filter. Permeate from the latter is fed to a bladder within a storage tank. Concentrate from the membrane filter is fed to and used within the storage tank as squeeze water for the bladder. When a faucet that delivers permeate to the user is open, squeeze water is used to cause permeate to flow out of the storage tank through an impurity filter to supply the faucet. A valve unit is included to control the amount of squeeze water fed to the storage tank and to regulate permeate flow so that the water outletted from the faucet remains at a constant pressure and provides relief as against overpressure in the system. A proportioning valve within the valve unit serves to maintain at all times a constant ratio of concentrate to permeate flow through the membrane filter for adequate cleansing of the membrane.

  • Patent number: 5114570
    Abstract: A water filter cartridge has a cylindrical shell. A conduit runs between closing end walls and is disposed within a filtration material. There are additional openings in the respective end walls for communicating the flow of water through the material. A water filtration element of a porous medium is shaped to nest within a portion of the shell encircling a corresponding portion of the filtration material and defining space between the medium and the inner side wall of the shell with that space being in the water flow path from one of the end walls and the material through the medium. A reference color is exhibited over a portion of the exterior side wall of the shell adjacent to the location of the medium inside the shell, and the medium exhibits a given color upon beginning of usage but changes color with continued usage in response to its entrapment of matter in the water. The shell is transparent over the medium to enable the user to compare the medium color to the reference color.
