Patent number: 7591059Abstract: Methods and apparatus for making a connection that can be rotationally locked by expansion are disclosed. Threaded tubular ends include a slot cut across a thread at a location along the circumference of the thread. Threading two tubular members that have the slot disposed in either or both of a pin or box end of the tubular members establishes the connection. The slots represent no impediment to the make-up or break-out of a box by pin connection prior to expansion. During expansion of the connection, the threads of either the box or pin end are forced via plastic flow into the slot in the corresponding thread. This results in locking the connection and preventing relative rotation between the two tubular members, which could otherwise loosen the connection.Type: GrantFiled: September 13, 2005Date of Patent: September 22, 2009Assignee: Weatherford/Lamb, Inc.Inventors: Iain C.

Publication number: 20090199390Abstract: The device prevents the loss of articles otherwise susceptible to falling behind furniture, appliances, fixtures or equipment or other large objects placed next to a wall which are not easy to move or reach under such as, but not exclusively, couches, wardrobes, desks, washers, dryers, refrigerators, filing cabinets and dressers. The compressible and flexible device is fitted from above into the crevice between the furniture and the wall. It is held in place by friction created by the pressure caused by the deformation of the device between the furniture and wall. The device, when flexed or compressed, creates a u-shaped channel which catches valuables such as jewelry, makeup, currency, papers, office supplies or other items which are left on top of furniture and which without such invention, may otherwise fall behind the furniture where it would be difficult or impossible to retrieve.Type: ApplicationFiled: January 15, 2009Publication date: August 13, 2009Inventor: Howard A. Dobelle

Publication number: 20090189434Abstract: A vehicle seat frame provides a tilting feature for tilting the seat cushion. The frame includes side brackets (20) with a torsion tube (60) laterally—extending through an aperture (100) of the side brackets. The torsion tube is fitted against the side bracket through an internal swaging procedure to allow smooth rotation of the torsion tube within the side brackets. The torsion tube includes an annular protrusion (200) which provides an axial locking feature that tightly secures the subcomponents placed onto the torsion tube during vehicle operation.Type: ApplicationFiled: June 2, 2006Publication date: July 30, 2009Inventors: Matthew C. Jones, Paul Brown

Publication number: 20090070984Abstract: A coupling between a device and a mating part includes an elastic material and perhaps a tensioner coupled to the elastic material. The elastic material is wrapped around at least part of the device. The tensioner or other method is used to stretch the elastic material, thereby reducing the thickness of the elastic material. With the thickness of the elastic material reduced by the stretching, the device is inserted into a hole in a mating part. Then the tension on the elastic material is removed, allowing the elastic material to increase in thickness, so as to fill at least part of the gap between the device and the mating part. The coupling may act as an effective heat transfer device for transmitting (by conduction) heat produced by the heat-producing device, to the mating part, which may act as, or be thermally coupled to, a heat sink.Type: ApplicationFiled: November 20, 2008Publication date: March 19, 2009Inventors: Alfred Sorvino, Hilario Tejeda, Randy Thompson

Publication number: 20080311998Abstract: A constant velocity joint, wherein all of those rolling elements excluding a plurality of rolling elements are divided into a plurality of rolling element groups and arranged along the inner diameter part of a roller member. The excluded plurality of rolling elements are dispersed in first to third cam grooves at intervals in the circumferential direction. When the rolling elements are pressed in the radial outer direction by the first to third pressing faces of a cam rotating in the arrow A direction, they are simultaneously press-fitted into first to third clearances between the rolling elements from the side of the inner diameter part of the roller member.Type: ApplicationFiled: May 17, 2005Publication date: December 18, 2008Inventors: Shouichi Nakao, Tsutomu Kawakatsu, Masanori Kosugi

Patent number: 7377021Abstract: Two components are held in at least partially overlapping relation to each other between a hold-down device and an essentially flat lower tool and then are joined together by pressing an auxiliary joining element into one of the components a sufficient distance to plastically deform the components in a manner that positively joins the two components together. A tool with an optional wobbling movement and/or an optional variable force is used to press the auxiliary joining element into the first component. The magnitude of force applied by the hold-down device affects the direction of plastic flow of the material of the components in relation to the flat lower tool.Type: GrantFiled: September 27, 2004Date of Patent: May 27, 2008Assignee: Fraunhofer-Gesellschaft zur Foerderung der Angewandten Forschung, e.V.Inventors: Reinhard Mauermann, Fred Jesche, Stephan Dietrich, Lutz Lachmann
