Patent number: 7490870Abstract: A hydraulic flange connection having a formed tube in physical conjointness with a contoured sleeve member, the conjointness including the sleeve member having a cylindrical body bore, a cylindrical outer portion tapering at one axial end into a frustoconical portion abutting one bore end, the cylindrical outer portion also merging into an annular outer end surface having inner and outer edges defining a bowl-shaped recess with a raised annular inner end surface; the tube having a cylindrical portion extending into and through the sleeve member bore, a radial flange portion thereof including an axially outwardly-directed, openly curved, circumferential radial groove, with an inner surface of the flange portion conforming axially and radially with an abutting complementary surface of the bowl-shaped outer recess portion in a fully nesting retention relationship. Details of achieving the conjointness between the tube and the sleeve member are also set forth in product-by-process claim recitation.Type: GrantFiled: March 1, 2006Date of Patent: February 17, 2009Assignee: Parker-Hannifin CorporationInventors: Atul Shah, Daniel A. Waina

Patent number: 6015499Abstract: A filter media for physically separating agglomerations of abrasive particles from a chemical-mechanical polishing (CMP) process slurry stream. The media is provided as being formed of at least one fabric sheet having a first and second surface defining a first thickness dimension of the sheet therebetween, with the fabric being woven of polymeric monofilament fibers. In service, the slurry stream is supplied to the first side of the filter media, and is passed through the media to the second side thereof such that at least a substantial portion of the agglomerations of abrasive particles are retained on the first side of the media.Type: GrantFiled: April 17, 1998Date of Patent: January 18, 2000Assignee: Parker-Hannifin CorporationInventor: Daniel B. Hayden

Patent number: 5804762Abstract: An electromagnetic interference (EMI) shielding gasket for mounting on a substrate having a surface. The gasket is formed of a resilient, elongate core member extending along a central longitudinal axis and having an outer circumferential surface defininga cross-sectional profile, and an electrically-conductive outer member having an inner and an outer surface and extending from a first distal end to a sheathing portion. The sheathing portion of the outer member covers a portion of the circumferential surface of the core member and extends from a first proximal end to a second proximal end. The first distal end of the outer member and the first proximal end of the sheathing portion thereof define a first inner shear surface therebetween which is attachable to the substrate. The uncovered portion of the circumferential surface of the core member defines an interface surface for disposition on the surface of the substrate.Type: GrantFiled: September 27, 1996Date of Patent: September 8, 1998Assignee: Parker-Hannifin CorporationInventors: Peter M. Jones, Joseph C. Houle

Patent number: 5781412Abstract: Conductive cooling of a heat-generating electronic component disposable in spaced-apart adjacency with a surface of a thermal dissipation member to define a gap of predetermined width therebetween. A curable composition is provided as formed of an electrically-insulating polymeric binder having thermally-conductive, electrically-insulating filler particles dispersed therein. At least a portion of the filler particles is of a maximum average diameter about equal to the predetermined width of the gap. A layer of the composition is disposable in conductive heat transfer contact with the electronic component and the surface of the thermal dissipation member, and is cured to form an interlayer within the gap.Type: GrantFiled: November 22, 1996Date of Patent: July 14, 1998Assignee: Parker-Hannifin CorporationInventor: Miksa de Sorgo

Patent number: 5701758Abstract: An accumulating vessel for use in a refrigeration system wherein a partially vaporized refrigerant is circulated therethrough. The vessel is constructed as a generally cylindrical housing having first and second end portions, and a body portion with a generally continuous circumferential inner surface, the portions together defining an internal chamber. An inlet tube opens into fluid communication with the internal chamber at a first location defining an inlet port, with an outlet tube opening into fluid communication with the internal chamber at a second location defining an outlet port. A baffle is received within the chamber intermediate the inlet and outlet ports for deflecting refrigerant from the inlet port over the outlet port.Type: GrantFiled: August 21, 1996Date of Patent: December 30, 1997Inventors: Cary Haramoto, Tom C. Wilson

Patent number: 5683120Abstract: A fitting assembly for a releasable connection with a distal tubing end. The fitting includes a generally annular body formed as having an internal bore with a radial surface describing an internal gland having a forward end wall defining a contact edge with the radial surface of the bore. A collet is journalled coaxially within the bore for translational movement within the gland of the body as having a generally cylindrical wall portion expandable to receive the tubing end therethrough. The wall portion is divided longitudinally into at least a pair of arcuate, cantilevered segment extending resiliently between respective distal and proximal ends. Each of the segments has an inner projection disposed adjacent the distal end thereof, and an outer camming portion which extends from a first rearwardly-inclined ramp surface to a generally-contiguous second rearwardly-inclined ramp surface.Type: GrantFiled: June 3, 1996Date of Patent: November 4, 1997Assignee: Parker-Hannifin CorporationInventors: David J. Brock, Kimberly J. Gilbert, Lyle E. Parrish

Patent number: 5647398Abstract: A fluid coupler connectable with a fitting of a variety which extends from an externally-threaded forward coupling end to a rearward port end. The coupler includes a body having an internal fluid passageway and valve stem. A distal end of the valve stem has a forward surface defining a seating portion, and a rearward surface engageable with a poppet valve of the fitting. A valve sleeve is received coaxially over the valve stem to define a fluid flow path therebetween. A rearward second end of the valve sleeve defines an outer periphery and an inner periphery configured to be received within the seating portion of the valve stem, and has a rearward confrontation surface with a seal member rotatably received within a mounting groove thereof. The valve sleeve is biased in a rearward first position wherein the second end thereof is received within the seating portion of the valve stem closing the fluid flow path, and is movable to a forward second position opening the fluid flow path.Type: GrantFiled: August 9, 1996Date of Patent: July 15, 1997Assignee: Parker-Hannifin CorporationInventor: Dennis C. Giesler
