Title: Sidewall construction for rail road car
Inventor: FORBES JAMES W
IPC: B61F1/10
Filed: 1996-04-30
Abstract: A railroad freight car has longitudinally extending and spaced apart side beams. Each of the side beams has top and bottom longtudinally extending, spaced apart chord members. The bottom member is shorter in length than the top member. Each beam includes a planar sidewall extending between the top and bottom chord members. The side beams each have flanged bottom edges adjacent to the trucks. The bottom edge has an inboard straightedge portion, an intermediate curved portion and an outboard straightedge portion. The inboard portion is joined along its length to the bottom chord member. The curved portion extends upwardly from the inboard portion adjacent the terminal end portion of the bottom structural member and merges with the outboard portion of the bottom edge of the side beam. The curved portion defines a curved edge having a positive slope of constantly decreasing value when measured from the inboard portion to the outboard portion. The side beam has a one-piece curved flange connected to the terminal end of the bottom structural member and to the curved portion of the bottom edge of the sidewall along the entire length thereof. The continuous curvature of the flange is designed to reduce stress risers associated with geometric discontinuity, to enhance fatigue resistance of the flange itself and the end structure, and to facilitate access by an operator to a truck supporting the end structure.

Title: Arrangement in a gripper mechanism for a free pipe/rodlike end portion of a downhole tool
Inventor: BAKKE STIG
IPC: E21B31/18
Filed: 2001-09-26
Abstract: A gripper mechanism (22) suspended in a coiled tubing/wireline in a well serves to releasably hold a downhole tool or other piece of equipment positioned downstream, via a tubular connecting element (10). The gripper mechanism (12) comprises axially, two relative to each other, movable coaxial parts (18, 16), a gripping part (18) designed to grip said connecting element (10) and an actuating part (16) designed to exert a radial clamping effect on the gripping portion (18a) of the gripping part (18) when this is in engagement with said connecting element (10). The clamping effect is due to complimentary conical face on opposite sides of the two parts (16, 18) of the gripper mechanism (12) being forced against each other by the axial displacement of one part (16) relative to the other part (18) in one direction (the upstream/pull-up direction). In order to enable a small cone/coning angle to be used at these complimentary conical faces, while at the same time ensuring that the conical faces do not get wedged to each other across a longitudinal course in the axial direction, the conical faces of each part (18 and 16) have been divided, so that each conical face comprises annular conical part faces (32, 28) and intermediate annular cylindrical part faces (34, 30).  The conical part faces (32, 28) have a mutually equal amount of taper and the same axial extent. The intermediate cylindrical part faces (34, 30) have a mutually equal axial extent.

Inventor: ROCH OLIVIER
IPC: B07C1/04
Filed: 2003-07-10
Abstract: The method of detecting overlapping postal items in a postal sorting installation ( 1 ) consists in detecting variation in the length of each item by causing each item to go past a plurality of proximity detectors ( 4, 5, 6, 7 ). The proximity detectors are situated at different points of the sorting installation ( 1 ) and they are configured to evaluate the length of each item. As they pass through the sorting installation, overlapping items shift progressively relative to one another due, in particular, to friction. Thus, the total length of a set of overlapping items tends to vary, such that evaluating variation in the length of each potential item serves to provide information that is reliable for detecting overlaps. Since it is relatively easy to evaluate the length of an item, the performance of the installation is improved at low cost.
