Patent CA-2620196-A1 (CA)
Inventor: GLOSSOP NEIL DAVID
IPC: A61B5/05
Filed: 2006-08-24
Abstract: The invention provides a method and system for performing an image-guided endoscopic medical procedure. The invention may include registering image-space coordinates of a path of a medical instrument within the anatomy of a patient to patient-space coordinates of the path of the medical instrument within the anatomy of the patient. In some embodiments, the image space coordinates of the path of the medical instrument may be predicted coordinates such as, for example, a calculated centerline through a conduit-like organ, or a calculated "most likely path" of the medical instrument within the anatomy of the patient. In other embodiments, the path of the medical instrument may be an actual path determined using intra-operative images of the patient's anatomy with the medical instrument inserted therein. The registered instrument may then be navigated to one or more items of interest for performance of the endoscopic medical procedure.

Title: Horizontal-multi-needle quilting machine and method
Inventor: JAMES MICHAEL A
IPC: D05B11/00
Filed: 2006-09-08
Abstract: A multi-needle quilting machine (10) and method uses two separately moveable bridges (21, 22) having selectively operable chain-stitching element pairs.  Either the material (12) or the bridges (21, 22) or both may be moved relative to the frame (11). Control schemes are provided to quilt continuous patterns, discrete patterns, linked multiple patterns, 360 degree patterns, or closely spaced patterns, preferably using a single drive servo motor (35, 36, 45, 46) for each bridge (21, 22) with the needle and looper drives phased relative to each other through a differential transmission. The needles and loopers can be driven out of phase, which is particularly useful in starting stitching sequences reliably. The parameters that define different products are used by a machine controller as a basis for deriving different quilting process steps, such as tack stitch sequences, thread wipe cycles and paths, thread pull-off distances and tension, and the need to sew additional lines to stabilize the material layers. Operator selection between quality and speed modes is provided. Simultaneous sewing of continuous and discontinuous patterns is provided

Patent CA-2628190-A1 (CA)
Inventor: PERKINS JOHN L JR
IPC: F04B47/02
Filed: 2008-04-02
Abstract: A downhole pump has a barrel and a plunger. The barrel has a first one-way valve and the plunger has a second one-way valve. The plunger is of the box end type. The pump prevents or minimizes gas lock by achieving high compression in the compression chamber between the two valves. The second valve is located close to the bottom end of the plunger. In the second valve, the valve seat is in contact with the seat plug, which seat plug has a seal. Alternatively, the valve seat is incorporated into the seat plug, which seat plug also has a seal. The plunger lacks reliefs at the bottom end and thereby achieves tight tolerances with the barrel, further contributing to high compression.

Title: Depolymerization of fluoropolymers
Inventor: VAN DER WALT IZAK JACOBUS
IPC: C08J11/00
Filed: 2006-11-24
Abstract: A process for depolymerizing fluoropolymers includes continuously feeding a solid fluoropolymer, in particulate form, into a horizontal cylindrical first reaction zone. The fluoropolymer particles enter the first reaction zone at one end. Within the first reaction zone, a central axle from which protrudes at least one paddle, continuously rotates. The rotating paddle serves to advance the fluoropolymer particles along the reaction zone while agitating them. As the fluoropolymer particles pass along the reaction zone, they are subjected to an elevated temperature, thereby depolymerizing the fluoropolymer into a fluoro-containing compound-rich gas phase. A residual solids phase is withdrawn at the other end of the first reaction zone, as is the gas phase. Optionally, the gas phase is passed through a second reaction zone which is also at an elevated temperature. The gas phase is quenched, thereby to recover the fluoro-containing compounds as gaseous products.
