20080201969 | Orientation Sensing Apparatus and a Method For Determining an Orientation - An orientation sensing apparatus includes a rotatable first member, an orientation sensor device fixed with the first member for generating orientation data relating to an orientation sensor device orientation, and a rotation sensor device for generating rotation data relating to rotation of the first member. A method for determining an orientation includes assembling a set of sensor data including the orientation data and rotation data and processing the set of sensor data to generate a set of corrected orientation data. The set of corrected orientation data includes the orientation data which has been corrected using the rotation data to reduce the effects of rotation of the first member and misalignment of the gravity sensor device. One or more sets of corrected orientation data may be processed to determine an inclination orientation of the first member or a toolface orientation of a second member which is connected with the first member. | 08-28-2008 |
20110116887 | ALIGNED AND AXIALLY LOADED PIG INJECTOR VALVE, THREADED CONNECTION AND METHOD FOR CONNECTING THREADED MEMBERS - A threaded connection comprising a first threaded member threadably connected with a second threaded member and an axial loading member. The first threaded member defines an opening for passage of the axial loading member therethrough, wherein the axial loading member protrudes from the first threaded member when in an extended position. The second threaded member has a loading surface defining a recess therein for receipt of the axial loading member when in the extended position such that the axial loading member bears on the loading surface and imparts an axial tensile force between the first and second threaded members. A method for connecting the members includes threading together the first and second threaded members, and passing the axial loading member through the opening defined by the first threaded member, so as to bear on the second threaded member within the recess, imparting the axial tensile force between the threaded members. | 05-19-2011 |
20110146076 | ALIGNED AND AXIALLY LOADED PIG INJECTOR VALVE AND METHOD OF ATTACHING - A method of attaching a tubular member, having an attachment flange defining a plurality of bolt holes, to a valve fitting comprising a valve body having a loading surface and a valve flange. The valve flange includes a flange, defining a plurality of bolt holes, for engaging the attachment flange and a plurality of axial loading members movable between a first retracted position and a second extended position protruding to bear on the loading surface. The method includes threading a threaded end of the valve flange onto a threaded end of the valve body, rotating the valve flange until the bolt holes of the valve flange are geometrically aligned with the bolt holes of the tubular member and moving at least one of the axial loading members into its second extended position to bear on the loading surface to impart an axial tensile force between the valve body and valve flange. | 06-23-2011 |

20080277988 | RECLINER CHAIR SHIELDING ASSEMBLY - This invention is related to a shielding assembly comprising a cover plate, upper and lower paddle arms, a circular plate, and a back plate for covering an opening in an arm of a recliner chair. The opening provides clearance for a drive tube that moves independently from the arm. The paddle arms are rotatably coupled to the cover plate, wherein rotation is restrained by tension devices. The circular plate is slidably disposed between the paddle arms and the back plate. The back plate is fixedly attached to the cover plate by fasteners that limit rotation of the paddle arms. In operation, if the drive tube moves upward or downward, the circular plate, having a bore circumferentially engaged to the drive shaft, moves therewith vacating a portion of the opening. One of the paddle arms may be deflected by the drive tube movement while another continues to overlie the vacated portion. | 11-13-2008 |
20090051201 | Sleep Over Recliner Chair - This invention is related to a sleep over recliner chair having a footrest mechanism and a recliner mechanism that operate independently of one another. The sleep over recliner chair includes a footrest, a seat, back, and a pair of spaced apart armrests. Further, the sleep over recliner chair includes a base, a reverse tilt mechanism coupled with the base, and a linkage mechanism coupled with the reverse tilt mechanism. The linkage mechanism includes a recliner mechanism and a footrest mechanism. The footrest mechanism is adapted to move between a first, closed position and a second, open position. The recliner mechanism is adapted to move between a first, upright position and a second, fully reclined position. Further, the footrest and recliner mechanisms operate independently of one another. | 02-26-2009 |
20100084895 | WALL-AVOIDING CONVERTIBLE OTTOMAN - This invention is related to an ottoman convertible to a seating unit comprising a back-support assembly, a seat-support assembly, a base frame, and a pair of opposed armrests. Additionally, the ottoman includes a linkage system comprising a plurality of pivotably interconnected linkages, where the linkage system is configured to rotatably couple the seat-support assembly to the back-support assembly, and translatably couple the seat-support assembly and the base frame. In operation, this furniture piece is moveable between a closed position, resembling an ottoman, and an open position, wherein the back-support assembly forms the backrest of a seating unit accessible to a seated occupant. Specifically, the pivotably interconnected linkages operate such that rearward rotational movement of the back-support assembly induces forward translation of the seat-support assembly in relation to the base frame. This movement coincidentally induces the pair of opposed armrests to raise. | 04-08-2010 |
20120235449 | Linkage Mechanism for a High-Leg Seating Unit - Provided is a linkage mechanism for a recliner that includes a seat-mounting plate, a base plate vertically supported by high-legs, a footrest assembly adapted to extend ottoman(s) forward when the recliner is adjusted from a closed to an extended position, and a seat-adjustment assembly. The seat-adjustment assembly includes an ottoman drive link that has a front end pivotably coupled to the footrest assembly and a rear end pivotably coupled to a mid section of a connecting link. The connecting link further includes a front end rotatably coupled to a forward portion of the base plate and a rear end rotatably coupled to a lower end of a rear pivot link. The rear pivot link further includes an upper end that is pivotably coupled to a rearward portion of the seat-mounting plate. The combined operation of three links above locates the seat-adjustment assembly above the base plate's lower edge during adjustment. | 09-20-2012 |
20130257111 | FULL-FLAT RECLINE LINKAGE - A linkage that provides a fully flat reclined position is described. The linkage includes a full-flat lift link pivotally coupled to a seat support link. A backrest support link couples to the lift link through an oblong aperture to provide additional range of motion. The lift link includes a laterally extending flange, the perimeter of which acts as a cam surface for a cam pin that obstructs reclining of the backrest support link when the rocker-recliner is in an upright position. When fully reclined, the linkage configures a footrest, seat portion, and backrest portion in a generally equal plane to provide a fully flat seating surface. | 10-03-2013 |
