During a measurement period subsequent to the first instance, a respective pulse magnitude measure is calculated based on each of a number of received pulse shape parameters (Pps). It is further investigated, for each pulse magnitude measure in the measurement period, whether or not the measure fulfils a decision criterion relative to the initial pulse magnitude measure. An alarm triggering signal (?) is generated if the decision criterion is found to be fulfilled.Type: ApplicationFiled: June 4, 2007Publication date: November 5, 2009Applicant: GAMBRO LUNDIA ABInventors: Leif Sornmo, Kristian Solem, Bo Olde

A filter-sensor integration comprises a lubrication filter assembly and at least one lubrication sensing assembly, wherein the lubrication sensing assembly comprising at least one sensor array, and the sensor array comprises of at least one sensor. The lubrication filter assembly comprises a housing which defines a chamber, wherein lubricating material enters the chamber through a filter material. The lubrication sensing assembly is embedded into the chamber of the lubrication filter assembly, and the lubrication sensing device is positioned relative to the filter material so that the at least one sensor of the sensor array senses in situ different parameters of the lubricating fluid, analyzes measured parameters to determine health of the system, and generates a control signal to protect machinery and processes.Type: GrantFiled: April 9, 2003Date of Patent: October 28, 2008Assignee: Rockwell Automation Technologies, Inc.Inventors: Frederick M.

Patent number: 7442292Abstract: A display provides an indication of the remaining useful life of a filter element by providing a visible level of fluid in the display corresponding to the remaining useful life. The fluid level is adjusted by a valve responsive to a pressure differential across the filter element. An increasing pressure differential produces an increased fluid level in the display. The display may be provided with markings indicating that a particular fluid level in the display corresponds to the need to change a filter cartridge containing the filter element.Type: GrantFiled: September 8, 2006Date of Patent: October 28, 2008Assignee: Stanadyne CorporationInventors: Leon P. Janik, David Ferreira, Michael J. Williams

Patent number: 7435347Abstract: A filter device has a filter housing part (10) with a filter element (12) and can be detachably connected to another filter housing part (20). A valve (24) clears a fluid path in the interconnected state of the housing parts (10, 20) with the filter element, and in the separated state of the housing parts (10, 20) from one another or without the filter element at least partially blocks it. Instead of known quarter-turn fastener and stopper solutions, a blocking is devised which can be economically implemented and which requires decidedly less installation space. A process for operation of a filter device is also provided.Type: GrantFiled: September 6, 2006Date of Patent: October 14, 2008Assignee: Hydac Filtertechnik GmbH.Inventor: Volkmar Klein

Publication number: 20080237142Abstract: Concentrator systems include a circulating fluid pathway passing through a pump, a filter, and a retentate container. An effluent outlet line communicates with the circulating fluid pathway through a filtering element within a body of the filter. The systems further include a control system. In some embodiments, the pump, filter, and retentate container may be secured within a portable container. Methods for concentrating a foreign substance within a fluid sample include establishing circulation of fluid through a fluid circulation path passing through a fluid pump, a filter body, and a retentate container. Fluid is caused to exit the fluid circulation path through a filtering element within the filter body, and at least one foreign substance is prevented from passing through the filtering element. A control system may be used to control at least one of a speed of the pump and a quantity of retentate within the retentate container.Type: ApplicationFiled: April 2, 2007Publication date: October 2, 2008Applicant: Battelle Energy Alliance, LLCInventors: Michael V.

Publication number: 20080203025Abstract: An apparatus and methods for producing purified drinking water are disclosed. A hand pump is used in a closed system to generate pressure sufficient to pass the untreated water through a system of filters and a reverse osmosis membrane. The system preferably includes an ultrafiltration filter. The resulting water is substantially pure, being free of bacteria and having a significant amount of minerals and salts removed to make it safe for drinking. The system can produce enough potable water to supply the daily needs for a small village.Type: ApplicationFiled: November 16, 2007Publication date: August 28, 2008Applicant: 350 CAMBRIDGE PARTNERS, LLCInventors: Michael H. Francisco, Subhash Mehra, Sumeet Mehra

Patent number: 7410587Abstract: A method and system are provided for high-precision separation of pharmaceutical or biotechnology liquids. The separation can be in accordance with direct flow filtration, tangential flow filtration or preparative chromatography. Movement of the pharmaceutical or biotechnology liquid within a flow path is controlled according to a selected pattern. Selected patterns include automatically and progressively increasing the flow rate within the unit, automatically and progressively increasing the pressure within the unit or initially proceeding according to a relatively high constant flow rate and switching to a relatively high constant pressure at a time when a given parameter is attained.Type: GrantFiled: August 3, 2004Date of Patent: August 12, 2008Assignee: Scilog, Inc.Inventor: Karl G. Schick

Publication number: 20080135465Abstract: A load control system and apparatus to control the load to different elements is disclosed. The load control system is attached to both an air conditioner and a pool filter system. The pool filter system has a predetermined run time and is only operating when the air conditioner is not. When the air conditioner turns on, the load to the pool filter system is disconnected. When the air conditioner turns off, the load is returned to the pool filter which resumes running at the point in the run time where the pool filter had previously left off. The load control system provides a more efficient and better use of energy resources.Type: ApplicationFiled: December 8, 2006Publication date: June 12, 2008Inventor: SHAWN DAVIS
