Patent number: 7132047Abstract: The present invention provides a filter apparatus for use in removing impurities and acids contained in a fluid that includes a particulate filter and an acid-neutralizing filter. Preferably, the particulate filter and the acid-neutralizing filter are positioned within a housing. A conduit having a pressure reduction section is arranged to create a pressure differential across the acid-neutralizing filter such that a portion of the fluid to be filtered by the filter apparatus passes through the acid-neutralizing filter.Type: GrantFiled: August 31, 2005Date of Patent: November 7, 2006Assignees: Baldwin Filters, Inc., D-A Lubricant Company, Inc.Inventors: John H. Beard, Allan Roush

Patent number: 7001507Abstract: A system to restrict and remove debris and pollutants from runoff water received from surrounding areas. A receptacle receives the runoff water, and a grate detains the heavier part of its solids burden. A first screen within the receptacle detains solids of lesser size. Water passed by the first screen encounters a tubular second screen in the receptacle which passes water that was additionally screened by it and sends it to a downstream system. A weir at a sensitive level in the receptacle can by-pass the second screen. The second screen is preferably rotatable.Type: GrantFiled: May 22, 2003Date of Patent: February 21, 2006Assignee: Carson Industries LLCInventors: Michael M. Orozco, John K. Pickrell

Patent number: 6986428Abstract: The present invention includes a membrane construction for selectively transferring a constituent to or from a fluid. The membrane construction includes a multi-layer fluid impermeable support sheet having a plurality of supports on at least one side of the support sheet that form a plurality of flow channels. At least one layer of the multi-layer support sheet is a bonding layer. A fluid permeable layer extends over the flow channels and is bonded to the plurality of the supports by the bonding layer.Type: GrantFiled: May 14, 2003Date of Patent: January 17, 2006Assignee: 3M Innovative Properties CompanyInventors: Jonathan F. Hester, Brian E. Spiewak, Philip D. Radovanovic, Stefan R. Reimann, Robert S. Kody

Patent number: 6942796Abstract: A filter unit is disclosed suitable for use in a filter housing. The filter unit comprises superposed and spaced-apart inclined lamellar structures, preferably in the form of hollow truncated cones, each having a lower end side opposite an upper end side and a passage for a flow of liquid between each two of the lamellar structures. Each passage has an inlet for receiving an inflow of liquid to be filtered and an outlet for discharging an outflow of filtered liquid. In each of the passages, an overflow dam wall following a sinuous path is obstructing the flow of liquid and retains particulate matter contained in the liquid. The filter unit is mounted vertically in a filter housing. The invention also concerns a prefilter comprising a filter unit as described above mounted vertically in a filter housing.Type: GrantFiled: March 23, 2001Date of Patent: September 13, 2005Assignee: Premier TechInventors: Roger Lacasse, Pierre Talbot, Henri Ouellet, Bernard Juneau
