Title: A method for producing a fiberoptic waveguide with a phase shift segment
Inventor: GABUS PHILIPPE
IPC: G02B6/10
Filed: 2000-11-28
Abstract: A method is described for producing a fiberoptic waveguide with a basic segment (11) and a phase shift segment (12), the basic segment (11) and phase shift segment (12) having fiber cores (K) of the same form and the fiber cores being aligned at a defined angle (.alpha.) to one another. In the method, use is made of an optical fiber (1) having a fiber core (K) of the abovenamed form, which fiber is twisted at least approximately by the abovenamed defined angle (.alpha.) and held fixed in this torsional position. Subsequently, a stress-relief zone (13) is heated inside the twisted fiber (1) until the torsion is released inside the stress-relief zone (13) and the basic segment (11) is produced on one side of the stress-relief zone (13) and the phase shift segment (12) is produced on the other side. In this case, the fixing of the torsional position is maintained until after solidification of the stress-relief zone (13).

Patent CA-2340985-A1 (CA)
Inventor: KURJANOWICZ WLODEK
IPC: G11C11/4097
Filed: 2001-03-14
Abstract: A high-density folded bitline memory array architecture is disclosed. High memory cell packing density is achieved by dividing polysilicon wordlines into short individual segments in the folded bitline scheme. Each wordline segment forms the gate of one or two DRAM memory cell transistors, and each segment is connected to a metal wordline, or conductor having low resistivity. By eliminating spaces between the memory cells due to passing wordlines, a cell arrangement and density similar to open bitline schemes is achieved. Further packing is obtained by arranging two columns of memory cells parallel to each bitline, each column offset with the other by a predetermined pitch.  Therefore, by increasing the number of memory cells connected to each complementary bitline pair, each bitline pair can be cut in half and connected to its own bitline sense amplifier to reduce the bitline capacitance. Hence the memory cell architecture of the present invention occupies less area, and operates with faster speed than memory cell architectures of the prior art.

Patent CA-2342657-A1 (CA)
Inventor: GRAVES KYLE
IPC: E21B21/10
Filed: 2001-03-30
Abstract: The present invention is a method and apparatus for the completion of wells in which the production tube is run and cemented with only one downhole trip into the well. The completion tool string includes a pressure activated cementing valve, an external casing packer, a pressure activated production valve and a plug landing collar. This tool series is assembled near the end of a production tube string between a well production screen and a well production packer. With the production screen in place, an opening pump-down plug is delivered against the landing collar to seal the internal bore of the tube string below the pressure actuated production valve. Fluid pressure within the tube string is raised to inflate the external casing packer against the borehole wall or casing. Additional pressure increase opens the pressure actuated cementing valve. The desired quantity of cement is pumped down the tubing bore and through the cementing valve into the borehole annulus. Cement flow is forced toward the up-hole direction by the external casing packer which blocks the annulus below the cementing valve. A closing pump-down plug caps the cement volume and is driven down the tubing bore by water or other well working fluid. The closing plug engages a valve closing seat in the cementing valve. Increased fluid pressure behind the closing plug first closes the cementing valve and second, shears the seat retaining pins to drive the closing plug against the fluid column between the two plugs. The resulting fluid pressure increase opens the pressure actuated production valve to purge the residual cement between the plugs and open a well fluid flow path around the plugged landing collar into the production flow tube.

Title: Strand guide eye and method of winding a package using the same
Inventor: GALLOWAY EUGENE V
IPC: B65H57/28
Filed: 2000-01-25
Abstract: A guide eye (200) for use with a traverse mechanism (110) of a strand (44) package (300) winder (100) is positioned with respect to the surface of the package (300) during the package (300) build process so that the guide eye (200) contacts the package (300) surface in the larger diameter, end regions (304, 306) of the package (300). This positioning provides a minimal free length (150) between the point at which the strand (44)s leaves the guide and the point at which the strand (44) contacts the package (300) surface, giving better control over the placement of the strand (44) onto the package (300) surface, particularly in the end portions (305, 307) of the package (300).  Further, the guide eye (200) is pressed against the package (300) surface, slightly compressing the surface and pressing a portion of the preceding stand courses against the package (300). This pressure helps to fix the strand (44) in the position in which it was laid down to reduce displacement of the strand (44) course during the package (300) build process.
