Patent number: 9322811Abstract: A fluidic connection system may comprise a port which includes a capillary tube receptacle with an end seal face and a threaded wall. The fluidic connection system may also comprise a capillary tube that includes a front end face for sealingly abutting against the end seal face of the port. On the capillary tube, a flange may be affixed at a distance from the front end face of the capillary tube. The fluidic connection system may further comprise a fitting nut that includes an axial hole to allow the capillary tube to pass therethrough and a matching threaded wall corresponding to the threaded wall of the port. The fitting nut may be slidably coupled with the capillary tube behind the flange. The distance at which the flange is affixed may be predetermined such that when the flange is pushed forward by the fitting nut, the front end face of the capillary tube abuts directly against the end seal face of the port.Type: GrantFiled: November 12, 2012Date of Patent: April 26, 2016Assignee: DIONEX CORPORATIONInventors: Michael John McAdams, Milton Liu, George N.

Patent number: 8313476Abstract: A inert sampling needle is provided for piercing a septum of a vial containing a sample. The sampling needle includes a hollow rigid support member having an inner wall, an outer wall, and a septum-piercing end. The sampling needle also includes a sheath member affixed to the rigid support member. The sheath member covers the septum-piercing end of the support member, the inner wall, and at least a portion of the outer wall adjacent the septum-piercing end to isolate the support member from the sample. Preferably, the sheath member is formed of polyetheretherketone and is affixed to the rigid support member by heat fusing. A method of forming, and a method of using the inert sampling needle is also disclosed.Type: GrantFiled: June 14, 2006Date of Patent: November 20, 2012Assignee: Dionex CorporationInventors: Jeff Thompson, George N.

Patent number: 8037788Abstract: A tight-spot fitting includes an elongated body configured to be inserted into and extracted from an aperture of a device, a user-operable head configured to be manipulated by a user to rotate the elongated body with respect to the aperture of the device, a depression in the user-operable head dimensioned and configured to receive a corresponding driver, and a through-bore extending through the elongated body and the user-operable head into the depression. The through-bore is configured and dimensioned to receive a line therethrough such that when the elongated body portion is inserted into the aperture, the line spans the aperture and through-bore, and extends through the depression.Type: GrantFiled: July 24, 2008Date of Patent: October 18, 2011Assignee: Dionex CorporationInventor: George N. Proper

Patent number: 6918595Abstract: A high-pressure pumping system including an energizing seal component having an aperture extending therethrough and a seal jacket component having a base and a toroidally-shaped flared membrane extending from the base. The body and the flared membrane are monolithically formed of an inert polymeric seal material. The flared membrane extends through the aperture and encircles the energizing seal component to isolate the energizing seal component from fluid of the pumping system. The flared membrane may extend axially from the body and encircle the energizing seal component. The flared membrane may encircle the energizing seal component and overlaps a portion of the base. The seal jacket component may be formed around the energizing seal component. The seal jacket component may include a flange extending radially outwardly from the base.Type: GrantFiled: November 22, 2002Date of Patent: July 19, 2005Assignee: Dionex CorporationInventor: George N.

Publication number: 20040256811Abstract: A seal for a high-pressure pumping system includes an energizing component having an aperture extending therethrough, and a seal jacket component. The seal jacket component includes a base and a flared membrane extending from an inner perimeter of the base, the flared membrane extending through the aperture, encircling the energizing component and overlapping a portion of the base to isolate the energizing component from fluid of the pumping system. The flared membrane may include a forward face substantially perpendicular to the aperture and a circumferential frontal lip extending forwardly beyond the forward face. The forward face may include a thinned-wall section facilitating the transmission of an axial force therethrough and against the energizing component. The seal jacket further may include a support lip extending forwardly from an outer perimeter of the base to properly seat the energizing component against the base.Type: ApplicationFiled: May 18, 2004Publication date: December 23, 2004Inventor: George N. Proper

Patent number: 5285805Abstract: A stretch valve which achieves precise control of fluid flow rates through the use of a cylindrical elastomeric valve element. This elastomer element is installed within the cylindrical flow path of a valve body. The flow path has a diameter that is slightly smaller than that of the elastomer element, which is therefore constrained within the flow path. Longitudinal stretching of the elastomer element causes the diameter of the elastomer element to decrease. As a result, a flow path is opened. The further the elastomer element is stretched, the larger is the fluid path that is created. Therefore, precise control of the fluid flow rate is made possible.Type: GrantFiled: March 22, 1993Date of Patent: February 15, 1994Assignee: General Valve CorporationInventor: George N. Proper
