  • Patent number: 11235268
    Abstract: A filter cartridge including catches for ejecting the filter cartridge from a filter housing as the filter cartridge and filter housing are removed from a filter base is provided. The catches are configured to engage corresponding catches of the filter base to limit axial motion of the filter cartridge as the filter cartridge and filter housing are threadedly removed from the filter base.
    Type: Grant

  • Patent number: 9737833
    Abstract: A filter assembly, a filter cartridge and method of filter fluid are provided. The filter assembly includes a filter base, a filter housing and a filter cartridge within the housing. The filter cartridge strips water from the dirty fluid flowing through the assembly. The filter cartridge defines a pair of fluid flow paths extending through a central cavity thereof. The fluid flow paths carry and keep separated a flow of cleaned fluid after it passes through filter media of the cartridge as well as the water that has been stripped from the dirty fluid flow.

  • Patent number: 9341355
    Abstract: A layered structure for use with a high power light emitting diode system comprises an electrically insulating intermediate layer interconnecting a top layer and a bottom layer. The top layer, the intermediate layer, and the bottom layer form an at least semi-flexible elongate member having a longitudinal axis and a plurality of positions spaced along the longitudinal axis. The at least semi-flexible elongate member is bendable laterally proximate the plurality of positions spaced along the longitudinal axis to a radius of at least 6 inches, twistable relative to its longitudinal axis up to 10 degrees per inch, and bendable to conform to localized heat sink surface flatness variations having a radius of at least 1 inch. The top layer is pre-populated with electrical components for high wattage, the electrical components including at least one high wattage light emitting diode at least 1.0 Watt per 0.8 inch squared.

  • Patent number: 8877055
    Abstract: A filter with a drain valve is provided. The drain valve mounts within an opening of a housing of the filter. The drain valve has a knob mounted to a valve member thereof. At least one locking structure is disposed between the knob and the valve member to mechanically lock the knob to the valve member. Such a configuration reduces the likelihood that the knob will become inadvertently dislodged during operation.
