Publication number: 20110220560Abstract: A process, system, and component configuration are described that discourages customer acceptance/use of will-fit, reconditioned, and counterfeit product components, by determining whether or not a serviceable product component is genuine. If a component is determined to not be genuine, then appropriate action may be taken to warn operators and document such findings. For example, one or more markers are disposed or otherwise put on the subject serviceable product component and serves as a targeted feature, and/or a particular characteristic of the filter itself is identified as the targeted feature. A sensor is used to detect the targeted feature and obtain information unique to the serviceable product component. The targeted feature(s) identifies the particular serviceable component as genuine and forms the basis for determining whether a genuine component has been installed. In some circumstances, a fluid filter product is the component that is the subject detection.Type: ApplicationFiled: March 9, 2011Publication date: September 15, 2011Applicant: CUMMINS FILTRATION IP, INC.Inventors: Barry M.

A septum is positioned within the vessel and defines a lower chamber and an upper chamber. The septum includes an aperture that provides fluid communication between the upper chamber and lower chamber. The bioreactor also includes means for releasing pressure buildup in the lower chamber. In one configuration, the septum includes a releasable portion having an open position and a closed position. The releasable portion is configured to move to the open position in response to pressure buildup in the lower chamber. In the open position fluid communication between the lower chamber and the upper chamber is increased. Alternatively the lower chamber can include a pressure release line that is selectively actuated by pressure buildup. The pressure release mechanism can prevent the bioreactor from plugging and/or prevent catastrophic damage to the bioreactor caused by high pressures.Type: GrantFiled: October 12, 2006Date of Patent: April 20, 2010Assignee: Utah State UniversityInventors: Conly L.

Patent number: RE41761Abstract: A gray-water recycling system for reclaiming gray-water for use in toilets and lawn care. The system includes a reservoir adapted to treat gray-water and includes an intake pipe, an outlet pipe and an overflow pipe. An inlet coupled to the intake pipe supplies gray-water to the reservoir. A filter is fluidly coupled to the outlet pipe for filtering gray-water to define processed gray-water. A pump is fluidly coupled to the by a pipe. A first valve (24) controls flow of the processed gray-water from the pump. The first valve is fluidly coupled to the pump, a fresh water inlet and a processed gray-water outlet. The first valve is adapted to open the fresh water if the water pressure from the processed gray-water falls. Also included is a pressure valve (52) adapted to manually adjust the pressure of the processed gray-water outlet and to allow a flow of fresh water in the event the solenoid of the first valve fails to operate.Type: GrantFiled: March 11, 2004Date of Patent: September 28, 2010Inventors: Cecil A.
