Patent number: 8397756Abstract: A fluid conduit coupling assembly has a depressible latch mechanism that secures a first fluid conduit to a second fluid conduit via a first coupler and a second coupler. The first coupler connects to the first fluid conduit and the second coupler connects to the second fluid conduit. The depressible latch mechanism is formed by a pair of cantilevered buttons disposed in symmetrically opposed positions on one of the couplers. The cantilevered buttons have engagement lips that extend distally with catches that extend radially outward to engage a ridge formed on an interior wall of the opposing coupler. Fluid ports within the couplers interface when the couplers connect to provide fluid flow between the first and second conduits. Valves may be disposed in each of the couplers to arrest fluid flow when the couplers are detached and automatically open to allow fluid to flow when the couplers are connected.Type: GrantFiled: September 29, 2010Date of Patent: March 19, 2013Assignee: Nordson CorporationInventors: Trent Turner Packham, Francis J. Lombardi, Leonard L. Hofheins, Gregg D. Niven, Robert J. Elshof, Raymond L. Townsend, Richard W. Cairns

Publication number: 20120299290Abstract: A latch assembly for connection of conduit, the assembly comprising a female portion and a male portion, wherein each of the female portion and the male portion have a shell and a connection device. The connection device of the female portion includes a connection assembly with a molded-in slot, a release button, and a raised rib or alternatively is a connection opening. The connection device of the male portion includes a cantilevered region with a ramped engagement feature or alternatively is a raised cantilevered release button. When connected the cantilevered region or button deflects to accommodate the female portion until the ramped engagement feature or button engages the molded-in slot or connection opening, thus releasing the deflection. Depressing the release button disengages the latch allowing separation of the assembly.Type: ApplicationFiled: August 6, 2012Publication date: November 29, 2012Applicant: Nordson CorporationInventors: James D. Pisula, JR., Bruce A. Williams, Ravikumar Narayanan, Francis J. Lombardi, III, Robert J. Elshof, Marc Lalouette

Publication number: 20120299296Abstract: A compression connector for flexible tubing has a clamp fitting and a compression collar that securely fastens to the clamp fitting. The clamp fitting has an inner sleeve defining a lumen and an outer tapered sealing surface, grip fingers, and male thread. The compression collar has female thread for mating with the male thread of the clamp fitting and a conical surface for mating with the grip fingers and clamping them against the fluid tubing inserted into the compression connector. The grip fingers retain tubing sealed against the tapered surface of the sleeve without impeding fluid flow. Elimination of the barb on the outer diameter of a connector for fluid tubing eliminates the potential for trapped fluid. The inner diameter of the inner sleeve is substantially the same as the inner diameter of the fluid tubing in order to reduce turbidity in fluid flow through the system.Type: ApplicationFiled: May 24, 2012Publication date: November 29, 2012Applicant: Nordson CorporationInventor: Francis J.

Publication number: 20120227221Abstract: A clamp for sanitary fittings includes a clamp body formed of a first arcuate member and a second arcuate member movable about a hinge assembly from an open configuration to a closed, latched configuration. The hinge assembly detachably couples the first arcuate member to the second arcuate member. The hinge assembly includes an arcuate finger extending from an end of the first arcuate member, a pin-receiving recess formed within the arcuate finger, and a post formed on an end of the second arcuate member. Upon assembly, the arcuate finger cradles around the post and the post fits within the pin-receiving recess.Type: ApplicationFiled: March 7, 2012Publication date: September 13, 2012Applicant: Nordson CorporationInventors: Carl T. Whitaker, Bruce Williams, Ravikumar Narayanan, Francis J. Lombardi, III, Kenneth R. Davis

Patent number: 7806139Abstract: The present invention is a fluid conduit coupling assembly for coupling a first fluid conduit to a second fluid conduit. The fluid conduit coupling assembly comprises a first coupler and a second coupler. The first coupler is for connecting to the first fluid conduit and comprises a first housing and a first valve. The first valve comprises a first lever arm. The second coupler is for connecting to the second fluid conduit and comprises a second housing and a second valve. The second valve comprises a second lever arm. When a force is applied to couple together the couplers, at least a portion of said force is communicated to each lever arm, thereby causing each valve to pivot from a closed position to an open position. The first valve and first lever arm are contained within the first housing, and the second valve and second lever arm are contained within the second housing.Type: GrantFiled: January 20, 2006Date of Patent: October 5, 2010Assignee: Value Plastics, Inc.Inventors: Trent Turner Packham, Francis J.
