Patent number: 9903516Abstract: A press fitting includes a socket defining at one end an opening for insertion of an end of a tube, a sealing ring within the socket, and a gripping ring within the socket, arranged in front of the sealing ring in the direction of insertion of the tube, wherein the gripping ring is provided with at least two weakening features in the form of notches, being reducible in size by deforming the gripping ring when applying a pressing action on the socket such that an inner diameter D2 of the gripping ring is reduced. A joint assembly may include such a press fitting having a tube inserted therein.Type: GrantFiled: September 25, 2013Date of Patent: February 27, 2018Assignee: CONEX IPR LIMITEDInventors: Manouchehr Salehi-Bakhtiari, Steven Paul Webb

Patent number: 8432601Abstract: An electrochromic display module employing a unique combination of architecture and electrochromic composition to provide an extended life to the module. The architecture may involve the use of an extended seal about a perimeter of a display portion where the composition is located. In this manner, the rate of solvent leakage from the composition may be substantially reduced. Additionally, the electrochromic composition itself may make use of particular low volatility solvents and constituent combinations so as to discourage the amount particle generation therein. Ultimately, an electrochromic display module having a useful life of more than about 3 years may be provided.Type: GrantFiled: May 1, 2009Date of Patent: April 30, 2013Assignee: Gemalto, S.A.Inventors: Steven Paul Webb, Dennis Brestovansky, Craig Richard Berry, John Russell Kingery

Patent number: 8424179Abstract: A tool (20) for a pipe fitting arrangement in which a pipe is retainable arranged within a housing (1) by teeth (13) of a grip ring (12) placed within the housing, the tool comprising: first engagement means for engaging the pipe, said first engagement means having at least one part (12) adapted to enter the housing around the pipe in order to force the teeth of the grip ring out of engagement with the pipe, second engagement means for engaging the first engagement means as well as the housing in order to locate the housing relative to the tool, and a handle connected or connectable with the second engagement means. The first engagement means being connected to the second engagement means via at least one first joint being in form of a pivot (24f) and/or at least one first spring means (38) in order to be at least partly displaceable relative to the second engagement means, and a method using such a tool.Type: GrantFiled: January 31, 2008Date of Patent: April 23, 2013Assignee: Conex Universal LimitedInventors: Steven Paul Webb, Alan Richard Glaze

Patent number: 7823932Abstract: A press fitting arrangement includes a sealing ring to be housed within a bead of a press fitting into which a tube is to be inserted. There is at least one gap between the press fitting together with the sealing ring and the tube which is closed by pressing at least one portion of the press fitting. The sealing ring has at least one first portion along the majority of its circumference. Each first portion of the sealing ring has an outside diameter (SOD1) prior to fitment into the press fitting bead which is larger than the inside bead diameter (BID) and an inside diameter (SID1) prior to the insertion of the tube which is less than the tube outside diameter (TOD). Additionally, the sealing ring has at least one pair of diametrically opposing second portions, each second portion of the sealing ring comprising a recess between the two projections.Type: GrantFiled: April 19, 2007Date of Patent: November 2, 2010Assignee: IBP Conex LimitedInventors: Steven Paul Webb, Alan Richard Glaze

Publication number: 20100148495Abstract: A device for forming a press-fit connection with a tube, the device including a socket for insertion of an end section of the tube. The socket includes a wall having at least a first section extending in axial direction, the first section having at least one annular bead providing a housing for at least partially accommodating a sealing element within the socket, and two second sections. Each second section is located immediately adjacent to a bead and commences at a position along an axis of the socket at which a magnitude of a derivative of an outside radius of the wall with respect to the axial position has a local minimum. In addition, each second section has, for every azimuthal position, an inside radius with a minimum at an axial position where the first and second sections terminate and the minimum radius of each second section is smaller than the inside radius at the axial position where the second section commences.Type: ApplicationFiled: December 11, 2009Publication date: June 17, 2010Applicant: IBP IPR LimitedInventors: Alan Richard Glaze, Steven Paul Webb

Publication number: 20090001712Abstract: A pipe fitting arrangement in at least one embodiment comprises a pipe, a housing defining at one end an opening for insertion of an end of the pipe, a metallic grip ring and a sealing ring downstream the grip ring in the insertion direction of the pipe, the location of both the grip ring and the sealing ring between the housing and the pipe being defined by the housing, wherein the grip ring is provided with a first amount of first internal teeth directed toward the pipe in a first direction with a first inclination in the pipe insertion direction for engagement with the pipe, and with a second amount of second external teeth directed towards the housing in a second direction with a second inclination away from the pipe insertion direction for engagement with the housing. Further disclosed herein is a method for forming such a pipe fitting arrangement.Type: ApplicationFiled: February 1, 2008Publication date: January 1, 2009Applicant: IBP CONEX LIMITEDInventors: Steven Paul Webb, Alan Richard Glaze, Manouchehr Salehi-Bakhtiari

Publication number: 20080238088Abstract: A method for inserting a pipe into a socket and for removing the pipe out of the socket by making usage of a tool are provided herein. The pipe is retainable within the socket by teeth of a grip ring placed within the socket. In at least one embodiment, the method comprises (a) inserting the tool at least partly into the socket mouth into which the pipe is to be inserted, (b) extending the internal diameter of the socket mouth at least over a part of its circumference being smaller than the external pipe diameter when inserting the tool, (c) inserting the pipe into the socket mouth through a tool opening, (d) withdrawing the tool out of the socket, and (e) disengaging the tool from the pipe. Also disclosed herein are method elements for pipe withdrawal. The method elements in combination with the tool help avoid damage to the pipe.Type: ApplicationFiled: April 2, 2008Publication date: October 2, 2008Applicant: IBP CONEX LIMITEDInventor: Steven Paul Webb
