Patent CA-2325105-A1 (CA)
Inventor: JORDAN GARY D
IPC: E21B33/12
Filed: 2000-11-03
Abstract: A packoff assembly 10 for use in a wellbore includes a packer body 42, 43, and a packoff element 12, and a mandrel 40 each supported on the packer body. The packoff element supports a rigid formation ring 15 thereon, and extends continuously from above the rigid ring to below the rigid ring and acts to minimize an axial force required to set the packer assembly in the wellbore. Both the upper surface and the lower surface of the rigid ring may be tapered relative to a centerline of the packer body. According to the method of the present invention, the packer assembly may be reliably set in the wellbore by applying a relatively low axial force to the mandrel. This reduced axial force required to set the packer contributes substantially to the benefits of the packer assembly.

Abstract: A feed system for a cellulose pulp treating vessel (such as a continuous digester) is not limited by the required L/W ratio of the pump feeding a wood chip slurry to a high pressure transfer device, the feed system may be kept at a low temperature to minimize flashing of liquid into steam, and a return conduit from the treatment vessel to the transfer device high pressure inlet may be eliminated. Some of the liquid is removed from the slurry just before the low pressure inlet to the transfer device, and/or just after the high pressure outlet, to reduce the L/W ratio of the slurry by at least 0.25, e.g.  from 3.0:1 to 2.25:1 just before the low pressure inlet, and from 7.0:1 to 5.0:1 substantially immediately after the high pressure outlet.
Patent CA-2345307-A1 (CA)
Title: An optical fiber having an expanded mode field diameter and method of expanding the mode field diameter of an optical fiber
Inventor: WU QI
IPC: G02B6/34
Filed: 1999-09-20
Abstract: The present invention is directed to a generally small mode field diameter ("MFD") optical fiber having a core bounded by a cladding, a cleaved end, and an expanded mode field diameter. The expanded MFD is formed by thermally diffusing one or more dopants in the core of the small MFD optical fiber using a highly localized heat source. The resulting adiabatic taper has an expanded MFD that is optimized for connection to another optical fiber having a larger MFD. The adiabatic taper is formed in the smaller MFD optical fiber by aligning and abutting the cleaved ends of two fibers having different MFDs to form a splice seam. The splice seam is offset a predetermined distance from the center of the region heated by a heat source to splice the fibers and expand the mode field diameters. As the mode field diameters expand, the splice loss across the splice is monitored. When the splice loss is at or sufficiently close to a target loss, heating is terminated, and the spliced optical fiber is cleaved where the MFD of the smaller MFD fiber portion of the spliced optical fiber is optically expanded to match the MFD of another optical fiber.

IPC: B01D1/22
Filed: 1999-11-08
Abstract: In the production of water vapor, particularly in the production of especially clean water vapor, dissolved gases, mainly atmospheric gases, are removed from feed water. The feed water is sprayed by a spray nozzle mounted in a hemispherical chamber in a spray pattern which matches an area of an upper end of an arrangement of vertical feed tubes of a falling film evaporator. The dissolved gases are liberated quickly from the sprayed droplets and removed through outlets in the hemispherical chamber. The sprayed droplets collect at the upper ends of the vertical evaporation channels and are distributed evenly thereamong before atmospheric gases can be redissolved.

IPC: A63G31/16
Filed: 1999-11-10
Abstract: Apparatus for simulating motion in the form primarily of a seat having arrangements for providing the user with cues which influence the users perception of apparent motion, particularly sustained movements. A fixed sea t frame has a moveable seat from which can tilt about orthogonal roll and pitc h axes and be displaced linearly in the heave, surge and sway directions: all movements are small and are accompanied preferably by synchronised variation s in the apparent hardness of regions of the contact surface so that a user experiences the small relative displacements and apparent tendency to slip i n relation to the seat in synchronisation with other cues which result in an interpretation of the experience to simulate the effects of real motions without actually involving movement. This may reinforce the effects of a convention motion simulator, for example for flight training.

Inventor: MARKEY JOHN J
IPC: B29C48/08
Filed: 1999-12-08
Abstract: A process for making a protective and decorative surfacing film comprises extrusion coating a solventless polymeric material from an extruder die to form an optically clear first layer on a polyester carrier sheet travelling past the extruder die opening. The extrusion coated first layer is immediately cooled on the carrier sheet to harden it, followed by applying a pigmented second layer to the first layer. The composite paint coat is transferred to a reinforcing backing sheet, after which the carrier sheet is separated from the paint coat to expose the outer surface of the first layer as a high gloss surface with a high distinctness-of-image, providing a transparent protective outer coat for the pigmented second layer. The pigmented second layer can be solvent cast and dried or extruded and hardened as a separate coating on the fist layer. The composite paint coat can be bonded to a coextruded size coat and semi-rigid plastic substrate panel to form a thermoformable laminate. Techniques are disclosed for producing extruded clear films of exceedingly high optical clarity using a closed air flow transport and HEPA filtration system that removes airborne particles from the resin handling and extrusion process, thereby preventing micron-sized contaminants naturally present from many sources from entering the process and degrading ultimate film quality.

Filed: 2000-07-24
Abstract: A lateral-emitter field emission device has a gate (30) that is separated by  an insulating layer (40) from a vacuum- or gas-filled environment containing  other elements of the device. For example, the gate may be disposed external  to a microchamber (110). The insulating layer is disposed such that there is  no vacuum- or gas-filled path to the gate for electrons that are emitted fro m a lateral emitter. The insulating layer disposed between the emitter and the  gate preferably comprises a material having a dielectric constant greater th an one. The insulating layer also preferably has a low secondary electron yield  over the device's operative range of electron energies. For display applications, the insulating layer is preferably transparent. Emitted electrons are confined to the microchamber containing their emitter. Thus, t he gate current component of the emitter current consists of displacement curre nt only, and direct electron current from the emitter to the gate is prevented.  An array of the devices comprises an array of microchamber, so that electron  current from each emitter can reach only the anode in the same microchamber,  even for diode devices lacking a gate electrode. A fabrication process is specially adapted for fabricating the device and arrays of such devices, including formation in situ of a vacuum microchamber.
