Patent CA-2640372-A1 (CA)
Title: Article-rotating and centering conveyor
Inventor: DOWE ANDREW WILLIAM
IPC: B65G17/24
Filed: 2007-01-24
Abstract: A conveyor comprises two endless conveyor belts (1 , 2) arranged in parallel.  The upper surface of each conveyor belt (1 , 2) includes an array of belt rollers (3), each belt roller arranged to rotate with movement of the conveyor belts about an axis at an oblique angle to the longitudinal direction of the conveyor belts (1 , 2). The conveyor also includes a respective drive mechanism arranged to drive each conveyor belt (1 , 2). Each drive mechanism is arranged to drive the associated conveyor belt (1 , 2) selectively in a forward direction and a reverse direction independently of the direction of drive of the other conveyor belt (2, 1). The axes of the belt rollers (3) are aligned such that when each conveyor belt (1 , 2) is driven in the forward direction, the belt rollers (3) of the conveyor belt (1 , 2) rotate about their axes to urge an object on the upper surface of the conveyor belt (1 , 2) towards the other conveyor belt (1 , 2). The conveyor has the advantage that an object on the upper surface of the conveyor belts (1 , 2) can be re-orientating by moving the conveyor belts (1 , 2) in opposing direction and/or at different speeds, in order that the object will pass through a defined opening at the end of the conveyor.

Title: Latchable reaming bit
Inventor: MYHRE MORTEN
IPC: E21B7/20
Filed: 2006-08-11
Abstract: A drilling assembly supports a liner (34) for making a wellbore . The BHA (10) comprises a pilot bit (12) and a reamer (22) above it that is larger in diameter than the suspended liner. If the BHA (10) needs to be pulled out, the reamer (22) is brought into contact with the liner (34) and a latch mechanism (30) between the two engages as another latch (28) that had held the reamer (22) bit to the BHA (10) is released. The reamer bit (22) stays with the liner as the BHA (10) is pulled and later reinserted. On the way in the BHA (10) latches to the reamer bit (22) which then unlatches from the liner bottom (32) . Preferably, splines (24) and a shoulder (26) on the BHA (10) are used to drive the reamer bit as opposed to any power being transmitted through the latch between the BHA and the reamer bit. However, the latch mechanism between the BHA and the reamer bit could also provide torque and weight on bit for drilling operations. The process may be repeated.

Title: Endoscopic sleeve seal
Inventor: RUCKER BRIAN K
IPC: A61B1/018
Filed: 2007-05-24
Abstract: A medical sealing device (10) is provided that substantially seals around one or more medical devices (15, 16) that are placed into the working channel (17) of an endoscope; wherein the one or more medical devices have an irregular cross-sectional profile. When a sufficient back pressure or surface tension is present in the working channel, the sealing device collapses a portion of itself and conforms to a portion of the one or more medical devices present in the working channel, thus forming a seal around and between the one or more medical devices. The seal thereby substantially prevents the escape of fluids from the working channel.

Inventor: CARAZZONE JAMES J
IPC: G01V3/18
Filed: 2007-06-13
Abstract: Method for efficient inversion of controlled-source electromagnetic survey data to obtain a resistivity model of the subsurface of the survey area. The method extracts the dimensions and location of sub-surface structures as they may be revealed by existing seismic or other available high resolution survey data from the subsurface area (33). This structure geometry information is used to construct a discretization (grid, or mesh) for the inversion computation (34) that is different from the mesh used for the forward modeling calculations (32) in that (a) it has fewer and hence larger cells; and (b) the cells honor the assumed structural information. The inversion need only extract resistivity information (35), the geometry of the resistive structures being specified by the inversion mesh.

Patent CA-2666027-A1 (CA)
Inventor: MCCONAGHY TRENT
IPC: G06F17/50
Filed: 2009-05-15
Abstract: A system and method that does trustworthy multi-objective structural synthesis of analog circuits, and extracts expert analog circuit knowledge from the resulting tradeoffs. The system defines a space of thousands of possible topologies via a hierarchically organized combination of designer-trusted analog building blocks, the resulting topologies are guaranteed trustworthy. The system can perform a search based on a multi-objective evolutionary algorithm that uses an age-layered population structure to balance exploration vs. exploitation, with operators that make the search space a hybrid between vector-based and tree-based representations. A scheme employing average ranking on Pareto fronts is used to handle a high number of objectives. Good initial topology sizings are quickly generated via multi-gate constraint satisfaction. To explicitly capture expert analog design knowledge, data mining is employed on the sized circuits to: automatically generate a decision tree for navigating from performance specifications to topology choice, to do global nonlinear sensitivity analysis, and to generate analytical models of performance tradeoffs.
