Publication number: 20080018104Abstract: A novel gasket includes at least one gripping element embedded in an annular member for forming a seal between two tubulars. For tubulars having socket and spigot ends, the gripping element includes teeth for gripping an outer surface of the spigot end and a blunt tooth for contacting a front wall of the socket end. The blunt tooth rolls along the front wall during relative movement between the tubulars and can include a contacting face of a specialized geometry to adjust contact dynamics and/or roughened surfaces to increase the frictional contact between the blunt tooth and the front wall. The embedded element can also include at least four teeth arranged such that no more than two teeth normally grip the outer surface of the spigot end. One or more teeth can also include a transverse groove to enhance penetration into the outer surface of the spigot end.Type: ApplicationFiled: October 1, 2007Publication date: January 24, 2008Applicant: STAR PIPE PRODUCTS LTD.Inventors: Van Walworth, David Hook

Publication number: 20070120365Abstract: A preferred joint restraint includes a dampening force and a restraining force to control relative movement between a pad and gland and between the gland and bolt, respectively. The preferred restraint includes a gland, pads, and bolts. Preferably, a flexible member disposed in the pad selectively provides the dampening and retaining force. A preferred joint restraint also includes a pad and a bolt that coact to provide a controlled wedging action. The wedging action supplies supplemental tooth penetration and/or enhanced clamping force that stabilizes a shifting tubular member (pipe). A preferred tooth arrangement for a restraint pad produces an intermittent penetration pattern in the pipe. A preferred spacing member for a restraint tunes a clamping force generated by the restraint to accommodate variations in pipe geometry and/or materials. A preferred restraint is arranged according to a method that uses pipe expansion to provide an enhanced gripping action.Type: ApplicationFiled: January 26, 2007Publication date: May 31, 2007Applicant: Star Pipe Products, Inc.Inventors: Van Walworth, David Hook, Mark Bowsher, Ashish Jain

Publication number: 20070113366Abstract: A windshield wiper blade assembly is disclosed which comprises a resilient wiper blade having an axial passage through which a flexible support beam is positioned to provide structure. A universal connector element for connecting the blade assembly to a plurality of different wiper arms crimps onto the blade and support beam assembly approximately midway along the wiper blade in a manner which does not puncture nor interfere with the resilient windshield wiper material, while at the same time preventing the relative axial translation of the support beam within the windshield wiper blade as well as translation between the blade and the connector itself.Type: ApplicationFiled: July 27, 2006Publication date: May 24, 2007Applicant: Tenneco Automotive Operating Company Inc.Inventors: Van Walworth, David Hook, Craig Whitaker, Joseph Bacarella, George Moser

Publication number: 20070022556Abstract: A resilient windshield wiper assembly is disclosed which comprises a resilient wind-deflector portion molded or extruded to provide a receiving hollow for insertion of a support beam. The resilient wind-deflector portion has a feature strategically positioned and structurally effective to prevent the resilient portion from being rotated or twisted around the support beam. The wind deflector is symmetrical with respect to the axial orientation of the support beam. The symmetry allows conversion of the wind force components from lifting forces to normal forces acting to press and/or hold the wiper against the wiper surface even when subjected to side gusts or reverse head-wind forces. The symmetry further provides a strength member acting directly over the top of the wiping lip surface avoiding introducing a twisting force into the support beam.Type: ApplicationFiled: July 27, 2006Publication date: February 1, 2007Inventors: Van Walworth, David Hook, Craig Whitaker, Mark Howell, William McGinn, Joseph Bacarella

Publication number: 20060265830Abstract: An improved windshield wiper blade assembly having a resilient windscreen wiping element and further comprising a longitudinal passage there through. A support beam having a predetermined curvature and shape is positioned there within the passage having a generally complementary cross section to the longitudinal passage, preventing the rotational twisting of the resilient element around the beam. A further embodiment comprises a longitudinal fluid passage along the support beam in fluid connection to a windshield fluid supply. A plurality of apertures through the resilient member in connection with the fluid passage provide for the selective discharge of the fluid upon the windscreen. A still further embodiment comprises a wind deflector portion running at least partially along the resilient member for enhanced prevention of any twisting of the resilient member around the beam and increased downward force of the wiper assembly against the windscreen.Type: ApplicationFiled: February 10, 2006Publication date: November 30, 2006Applicant: Tenneco Automotive Operating Company Inc.Inventors: Van Walworth, Mark Boyle, Joseph Bacarella, David Hook, William McGinn, George Moser

Publication number: 20050275217Abstract: A novel gasket includes at least one gripping element embedded in an annular member for forming a seal between two tubulars. For tubulars having socket and spigot ends, the gripping element includes teeth for gripping an outer surface of the spigot end and a blunt nose for contacting a front wall of a gland that compresses the gasket against surfaces of the socket and spigot ends. The blunt nose rolls along the front wall of the gland during relative movement between the tubulars and can include a contacting face of a specialized geometry to adjust contact dynamics and/or roughened surfaces to increase the frictional contact between the blunt nose and the front wall. The gripping elements can also include at least four teeth arranged such that no more than two teeth normally grip the outer surface of the spigot end. One or more teeth can also include a transverse groove to enhance penetration into the outer surface of the spigot end.Type: ApplicationFiled: May 17, 2005Publication date: December 15, 2005Inventors: Van Walworth, David Hook

Publication number: 20050145149Abstract: This invention comprises a means to control stitch length of household sewing machines when used on free-motion quilting frames. A sensor in the form of a computer mouse or a pair of sensors in the form of optical encoders is used to determine the translational speed of the set of carriages that hold the sewing machine. This information is sent to electronic circuitry that converts this information to an electrical resistance which is applied to the foot pedal control electrical connector on the sewing machine. When thusly applied, this resistance sets the rotational speed of the sewing machine. This invention achieves stitch length uniformity by maintaining the proper relationship between the input signal from the sensor or sensors caused by carriage translation and the output resistance to the sewing machine which controls its rotational speed.Type: ApplicationFiled: October 26, 2003Publication date: July 7, 2005Inventor: David Hooke
