Patent number: 8206583Abstract: Fluid treatment elements substantially inhibit electrical charge imbalances and/or build-ups of electrical charges. A fluid treatment element may comprise a multilayer composite including an electrically conductive fibrous matrix, having an upstream side and a downstream side, disposed on a porous substrate, also having an upstream side and a downstream side, which supports the fibrous matrix. The fibrous matrix may include a combination of conductive and nonconductive fibers. The multilayer composite may also include a drainage layer positioned along one of the upstream side of the fibrous matrix and the downstream side of the porous substrate.Type: GrantFiled: August 26, 2008Date of Patent: June 26, 2012Assignee: Pall CorporationInventors: Ronald D. Hundley, Scott A. Whitney, Angela M. Griffin, Conrad J. Christel, Leonard E. Bensch, Kenneth M. Williamson, Joseph G. Adiletta

Patent number: 7455768Abstract: Fluid treatment elements substantially inhibit electrical charge imbalances and/or build-ups of electrical charges. A fluid treatment element may comprise a multilayer composite including an electrically conductive fibrous matrix, having an upstream side and a downstream side, disposed on a porous substrate, also having an upstream side and a downstream side, which supports the fibrous matrix. The fibrous matrix may include a combination of conductive and nonconductive fibers, wherein the conductive fibers include metal, carbon, or conductive polymer fibers and substantially inhibit an electrical charge and/or build-up of electrical charge. The conductive fibers of the electrically conductive fibrous matrix may comprise less than about 50% by weight of the conductive and nonconductive fibers and may have diameters in the range from about 1 ?m or less to about 10 ?m.Type: GrantFiled: September 6, 2006Date of Patent: November 25, 2008Assignee: Pall CorporationInventors: Ronald D.

Patent number: 7128835Abstract: A fluid treatment element for treating a fluid flowing through the element comprises a first conductive layer and a second conductive layer electrically connected to the first conductive layer. The element further comprises a nonconductive porous treatment medium between the first and second conductive layers. The first and second conductive layers are positioned to offset electrical imbalances caused by fluid flowing through the nonconductive porous treatment medium.Type: GrantFiled: November 22, 2000Date of Patent: October 31, 2006Assignee: Pall CorporationInventors: Ronald D. Hundley, Scott A. Whitney, Angela M. Griffin, Conrad J. Christel, Leonard E. Bensch, Kenneth M. Williamson, Joseph G. Adiletta

Patent number: 6332987Abstract: A coalescing element is provided which is capable of separating a continuous phase fluid from a discontinuous phase fluid. The coalescing element includes a wrap structure which facilitates the coalescing process by conglomerating smaller droplets of the discontinuous phase fluid into larger droplets which may be of a size that will prevent them from being re-entrained.Type: GrantFiled: June 18, 1999Date of Patent: December 25, 2001Assignee: Pall CorporationInventors: Scott A. Whitney, Kenneth M. Williamson, Michael A. Clendenning, James R. Hibbard, Angela M. Griffin

Publication number: 20010047967Abstract: A purification system for separating phases of a solid/liquid/liquid mixture includes at least one cylindrical filter element including a filter medium for removing solid particulate matter, the filter medium having a bubble point of at least about 200 inches of water, and at least one coalescing element in spaced relationship to the filter medium for coalescing into droplets a first liquid of a solid/liquid/liquid mixture, which first liquid is wholly or partly immiscible in and forms a discontinuous phase with a second continuous phase-forming liquid of the solid/liquid/liquid mixture. The filter element may be detachably mounted adjacent to the coalescer element.Type: ApplicationFiled: December 22, 1997Publication date: December 6, 2001Inventors: KENNETH M WILLIAMSON, SCOTT A.

Patent number: 6113784Abstract: A filter includes a cylindrical pleated filter element having a longitudinal axis, an inner and outer periphery, first and second end surfaces, and a plurality of longitudinal pleats. First and second end elements are sealingly arranged with the first and second end surfaces, wherein at least one of the end elements is an open end element. The filter element is a pleated composite that includes a filter medium, an upstream drainage medium and a downstream drainage medium. Each pleat includes a crown, a root, and a pair of legs. The legs of each pleat are joined to one another at the crown of the pleat and are joined to the legs of adjacent pleats at the root of the pleat. Each pleat leg abuts an adjacent pleat leg along the inner periphery of the filter element and the pleats extend from the inner periphery in a curved, an arcuate, an angled, or a straight nonradial direction to the outer periphery.Type: GrantFiled: August 3, 1998Date of Patent: September 5, 2000Assignee: Pall CorporationInventors: Richard C.
