| 20100161033 | GRADUALLY SELF-EXPANDING STENT - A gradually self-expanding stent includes a first plurality of stent cells including a first plurality of circumferentially adjacent structural members in mechanical communication with each other. The stent also includes a second plurality of stent cells including a second plurality of circumferentially adjacent structural members in mechanical communication with each other. The circumferentially adjacent structural members of the first and second plurality of stent cells have a compressed configuration and an expanded configuration. A restraining material is attached to each of the circumferentially adjacent structural members defining each of the second plurality of stent cells such that it substantially covers an entirety of each of the second plurality of stent cells in the compressed configuration. Over time, the restraining material releases the structural members defining each of the second plurality of stent cells, thereby allowing the second plurality of stent cells to assume the expanded configuration. | 06-24-2010 |

| 20110054925 | CLAIMS ANALYTICS ENGINE - Methods and systems for processing claims (e.g., healthcare insurance claims) are described. For example, prior to payment of an unpaid claim, a prediction is made as to whether or not an attribute specified in the claim is correct. Depending on the prediction results, the claim can be flagged for an audit. Feedback from the audit can be used to update the prediction models in order to refine the accuracy of those models. | 03-03-2011 |

| 20090279987 | PIPE HANDLING UNIT - A pipe handling unit particularly adaptable for use in association with slant wells includes a pipe manipulation mechanism mounted to a mobile pipe storage rack, which when sited adjacent to a drilling rig or service rig can transport pipe sections to or from the rig mast regardless of the angular orientation of the rig mast. The pipe manipulation mechanism includes a boom rotatably mounted to the storage rack, with two or more swivel arms mounted to the mast, with pipe grapple means connected to the outboard end of the swivel arms may be swivelled outward, about axes parallel to the boom, to a position in which the grapple means can grasp a pipe section held in the rig mast. The swivel arms may then be swivelled in the opposite rotation to rotate the pipe away from the mast. The boom and swivel arms are then manipulated in coordinated fashion to deposit the pipe section in the storage rack. | 11-12-2009 |
| 20100132520 | METHOD AND APPARATUS FOR SLOTTING TUBULAR STEEL - In a method for slotting a pipe, a sacrificial liner is inserted into the pipe and radially expanded into contact against the inner pipe wall surface, where-upon rotating blades are plunged through the pipe wall and partially into the sacrificial liner. The sacrificial liner prevents the formation of wickers, and prevents cuttings and cutting fluid from entering the interior of the pipe, thus facilitating production of wicker-free slotted pipe requiring reduced post-slotting cleaning. An apparatus for implementing the method incorporates a fixed seal sub-assembly and a movable seal sub-assembly, interconnectable to form an elongate assembly which is adjustable to suit different pipe lengths. A cylindrical re-usable liner is disposable around the assembled fixed and movable seal sub-assemblies, and sized for insertion into the sacrificial liner. The re-usable liner may be expanded by internal pressure, thereby expanding the sacrificial liner. Preferably, the slotting method uses slotting blades with curvilinear teeth thinner than the main blade body, to produce cuttings that are narrower than the finished slot width, and therefore easier to remove from the slots during slotting operations. | 06-03-2010 |

| 20110042979 | REMOTELY-OPERATED ROPE-THREADING TOOL - A tool for threading a rope through a distant eye or around an object out of reach, such as for elevating tarps into trees, or placing fall protection lines, or securing a distant object. The tool has two curved arms that extend out from the body in unison and converge at a point where the end of the rope is passed from one arm to the other. The arms are then retracted back into the body, pulling the rope through the eye or around the object. The arms are extended by pulling one control line and retracted by pulling a second control line. The tool is typically mounted on the end of a pole, although other mountings are possible. The shape of the tool enables ropes to be threaded through a large number of eye configurations and around objects of varying sizes, even if there are obstructions adjacent the eye. | 02-24-2011 |

| 20080202056 | Lightweight low profile floor structure - Longitudinal beams span between torque boxes located at each end. The beams attach to the torque boxes to prevent vertical movement or rotation about their horizontal axis, or a fixed end condition. The longitudinal beams cover the width of a platform used to support pallets, and the ends may have wheels for transport of the pallets. The torque box attaches to a moment beam to prevent rotation between the two members about the lateral axis. The torque box has a high strength to transmit all of the moment generated by the end condition through it and into the moment beam. This fixed end condition has the advantages of light weight, low deflection, and low beam depth. | 08-28-2008 |
