Patent CA-2328640-C (CA)
Title: Multiple trough coil car
Inventor: AL-KAABI MOHAMMED
IPC: B61D3/16
Filed: 2000-12-15
Granted: 2008-05-13
Abstract: A coil car has a pair of deep side sills and a trough structure mounted to, and suspended between, the deep side sills for carrying coils. The side sills extend between the rail car trucks and act as a pair of deep side beams for carryin g vertical loads. The deep side sills are arranged to extend above and below the center sill of the coil car to give vertical stiffness to the coil car. The top chord membe rs of the side sills are outwardly splayed relative to the bottom chord members of the side sills. Cross-bearers extend outwardly and away from the center sill to attach to th e side sills. The trough structure has three parallel, longitudinally extending troughs - a central trough lying between two laterally outboard outer troughs. Each trou gh is shaped to cradle steel coils, or other similar loads, between its inwardly a nd downwardly sloping shoulder plates. The shoulder plates are lined with cushioning to buffer coils during loading or travel. The outboard troughs are mounted abov e longitudinally extending stringers and are carried at a greater height relative to top of rail than the central trough. The car has coil stops to discourage longitudinal shifting of loaded coils. The coil stops have rollers to facilitate repositioning during loading, and a mid-span step and hand grabs to facilitate climbing over the coil stop by personnel walking along the trough structure.

Abstract: A wireless coiled tubing joint locator for locating joints or collars in a production tubing string. An electromagnetic coil assembly or giant magnetoresistive digital field sensor senses the increased mass of a pipe joint, and provides a signal to an electric circuit which generates a signal received by a pilot solenoid valve. The solenoid valve momentarily opens a pilot passageway which activates a piston to close a circulation port in the joint locator, resulting in an increase in a surface pressure reading observable by the operator. In one embodiment, a rupture disk is provided so that pressure cannot be applied to any downhole tool below the joint locator prematurely. A seat sleeve prevents premature communication of fluid to the rupture disk but can be opened by dropping a ball into the joint locator. A second embodiment may be used for either logging or washing operations or both. The electronic circuit can provide a selected one of a plurality of time delays. A fixed test period in the circuit delays activation of the time delay so that the joint locator may be tested before it is run into the well. The electric circuit and power supply are provided in a removable case.

Title: Embedded quadtree wavelets in image compression
Inventor: WANG MENG
IPC: H04N7/26
Filed: 1999-08-10
Granted: 2005-07-26
Abstract: The invention is a new effective and fast method and apparatus for still image compression. The present invention implements an embedded progressive sorting scheme in a quadtree-like structure. In contrast to zerotree-based methods for wavelet coding, the invented embedded quadtree wavelet (EQW) method exploits the inherent spatial self-similarity within individual layers of the multiresolution decomposition hierarchy. This self-similarity offers higher predictability of the data within the same resolution level, and therefore usually provides a higher performance in seeking a compact code. The computation involved in the EQW method is more efficient than in the zerotree wavelet coding, and the produced bitstream is more robust to channel noise. The present invention can be effectively used for object-oriented shape coding or region coding in image and video compression coding systems.

Title: Novel fluids and techniques for maximizing fracture fluid clean-up
Inventor: HINKEL JERALD J
IPC: E21B43/26
Filed: 1999-09-23
Granted: 2007-08-28
Abstract: The present invention relates to methods to stimulate the production of hydrocarbons from a subterranean formation (40). The present invention discloses methods to enhance the removal of fracturing fluid from a fracture (42) deliberately created in the formation (40), thereby increasing effective fracture (42) length, and thereby increasing hydrocarbon production. The methods of the present invention involve breaker schedules wherein the breakers are staged such that the fluid near the fracture (42) tip (46) breaks first creating a viscosity gradient which causes the fluid residdent in the tip (46) to move towards the wellbore (10) where it is more easily removed. Preferred embodiments of the invention involve the use of gas to foam the fluid in the early pumping stages to induce a density gradient, as well as the use of fibrous material in the latter pumping stages to stabiliz e the proppant pack as the energized fluid in the near-tip (46) squeezes through the near wellbore (10) region.

Title: Flexible stent and method of manufacture
Inventor: TOMONTO CHARLES V
IPC: A61F2/06
Filed: 2002-03-01
Granted: 2007-05-01
Abstract: A preferred embodiment of a stent provides a folded strut section that provides both structural rigidity and reduction in foreshortening of the stent mechanism. A flexible section provides flexibility for delivery of the stent mechanism. In a second embodiment, flexible section columns are angled with respect to each other, and to the longitudinal axis of the stent. These relatively flexible sections are oppositely phased in order to negate any torsion along their length. In yet another embodiment, the flexible connector can take on an undulating shape (like an "N"), but such that the longitudinal axis of the connector is not parallel with the longitudinal axis of the stent.   Finally, a new method is disclosed for making stents. The method consists of performing a standard photochemical machining process of cutting, cleaning and coating the tube with a photoresist. However, unlike former methods, the photoresist image is developed on the surface of the cylindrical metallic tube, which results in a controlled variable etching rate at selected sites on the cylindrical metallic tube during the etching process. Further embodiments provide living hinge connectors and connections along the length of the radial strut member.

Abstract: Damping of oscillations of the first bending mode of a wind turbine is performed means of one or more containers partly filled with a liquid for damping oscillations of the first natural bending frequency of the wind turbine. The damping means comprises a plurality of box shaped containers having a square cross section and being partly filled with liquid so as to provide a unidirectional damping with a logarithmic decrement of oscillations of the first natural bending frequency of the wind turbine of at least 4-8%.  For off-shore wind turbines, the combined excitation of the wind and sea waves requires more damping, the damping is preferably equivalent to a logarithmic decrement of 10-15%. Furthermore, the invention relates to damping of oscillation of the second bending mode of a wind turbine and to the combined damping of oscillations of the first as well as the second bending mode of the wind turbine.

Abstract: An apparatus (150) and method (300) for determining a density compensated fl ow rate of a material flowing through a vibrating conduit. Signals are received from sensors (105, 105') affixed t o the vibrating conduit (103A, 103B). An uncompensated flow rate of said material is then calculated from the signals. A density compensation factor is then determined from the uncom-pensated flow rate and non-linear information relating density to erro rs in flow rate. The density compensated flow rate is then determined by applying the density compensation factor to the uncompensated flow rate.
