Patent number: 8048315Abstract: Fluid treatment arrangements and methods involve a plurality of fluid treatment modules and a core assembly that extends through the plurality of fluid treatment modules. Each fluid treatment module has a feed region, a permeate region, and a fluid treatment medium separating the feed region from the permeate region. The feed region extends along a feed surface of the fluid treatment medium, and the permeate region extends along a permeate surface of the fluid treatment region. Feed fluid is directed along the feed region of each module, and a portion of the feed fluid passes as permeate through the fluid treatment medium, into the permeate region, and then into the core assembly. One or more control mechanisms are fluidly coupled to the permeate region of one or more fluid treatment modules to control a flow parameter in the permeate region of the module.Type: GrantFiled: July 28, 2008Date of Patent: November 1, 2011Assignee: Pall CorporationInventors: Thomas J. Fendya, Xianyao Shen, Tanweer ul Haq, Mark F. Hurwitz, Stephen A. Geibel

Publication number: 20080251442Abstract: Fluid treatment assemblies and elements may include a plurality of axially extending pleats and may be used to treat fluids, including gases, liquids, or mixtures of gases, and/or solids, in a crossflow mode of operation. For example, some fluid treatment assemblies and elements may be used to remove one or more substances from the fluid and may then function as separators, including filters and concentrators. Other fluid treatment assemblies and elements may be used to transfer substances between two fluid streams and may then function as mass transfer devices.Type: ApplicationFiled: September 26, 2006Publication date: October 16, 2008Applicant: PALL CORPORATIONInventors: Xianyao Shen, Thomas J. Fendya, Mark F. Hurwitz

Patent number: 4761000Abstract: A surgical table is provided which is capable of conventional surgical table functions and is provided with a radioluscent tabletop which may be horizontally displaced to allow radiographic procedures to be performed without requiring relocation of the patient. The surgical table includes a base member which may be locked to a floor mount pivot. The base member supports a table superstructure which may be raised and lowered and tilted relative to the longitudinal axis of the table as well as tilted relative to a lateral axis of the table. A carriage assembly is provided intermediate the tabletop and the superstructure which allows the translation of the tabletop both longitudinally and laterally. Locking means are provided to prevent the horizontal translation of the tabletop when the table is in the surgical mode.Type: GrantFiled: April 7, 1987Date of Patent: August 2, 1988Assignee: American Sterilizer CompanyInventors: Kenneth J. Fisher, Eric J. Schuldt, Thomas J. Fendya

Patent number: 4614015Abstract: A device for stabilizing/ejecting a lamp from a plug-in socket wherein the lamp is mountable in a frame. The device includes a spring member for stabilizing the lamp in the frame and an ejection member pivotally attached to the spring member. The ejection member includes an upper ejector, or cam formed therein for separating the socket from the lamp, an outwardly extending lower ejector for ejecting the lamp from the frame and a lever for sequentially actuating the upper ejector and the lower ejector in one stroke. The stroke moves the lever from a rest position in which the spring member is operative, through a transition position in which the upper ejector is operative to eject the socket from the lamp and to reinforce the spring member to stabilize the lamp during the socket separation. The lever moves from the transition position to a final position in which the lower ejector is operative to eject the lamp from the frame.Type: GrantFiled: October 2, 1985Date of Patent: September 30, 1986Assignee: American Sterilizer CompanyInventors: Arthur T. Nagare, Wolfgang Mueller, Thomas J. Fendya, Joseph T. Sestak
