Patent number: 9737833Abstract: 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.Type: GrantFiled: March 6, 2015Date of Patent: August 22, 2017Assignee: Baldwin Filters, Inc.Inventor: Stephen Schweitzer

Patent number: 9341355Abstract: 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.Type: GrantFiled: August 30, 2013Date of Patent: May 17, 2016Assignee: Metrospec Technology, L.L.C.Inventors: Wm. Todd Crandell, Anthony Mitchell Johnson, Tony Stephen Schweitzer, H. Vic Holec

Patent number: 8877055Abstract: 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.Type: GrantFiled: October 13, 2010Date of Patent: November 4, 2014Assignee: Baldwin Filters, Inc.Inventors: Stephen Schweitzer, Mitch Bendix
