Patent CA-2224554-A1 (CA)
Title: Process and device for testing deformable containers for tightness
Inventor: HEUFT BERNHARD
IPC: G01M3/32
Filed: 1996-07-05
Abstract: For the purpose of testing deformable containers (2) for tightness, a negative pressure is generated in the container (2) and the internal pressure is then measured. The negative pressure is generated by deformation of the container (2). A  sealing strip (6) is set on the container opening (8) in order to maintain the negative pressure in the container (2). In non--tight containers, the pressure increases relatively rapidly again to the ambient pressure.

Patent CA-2235913-A1 (CA)
Title: Spool valve loading method and apparatus
Inventor: JOHNSON LANE M
IPC: B23P19/04
Filed: 1998-04-24
Abstract: A method and apparatus for assembling a spool valve into a valve bore of a body by providing compressed gas to the valve bore at a pressure below the pressure of compressed gas supplied to a passage within a carrier body containing a spool valve substantially concentrically aligned with the valve bore to advance the spool valve from the passage into the valve bore. The compressed gas in the passage provides a force acting generally uniformly on the spool valve substantially concentrically aligning the spool valve within the passage. The compressed gas supplied to the valve bore also acts substantially uniformly on the spool valve tending to substantially concentrically align the spool valve within the valve bore when the spool valve is advanced therein.  While the gas in the passage and the valve bore align the spool valve, the higher pressure of the gas in the passage advances the spool valve into the valve bore.

Title: Set-top electronics and network interface unit arrangement
Inventor: HUMPLEMAN RICHARD
IPC: H04L12/56
Filed: 1996-11-21
Abstract: A set-top electronics and network interface unit arrangement is connected to an internal digital network interconnecting devices in the home. Entertainment services are introduced into the network through network interface units that are coupled to an external network and to the internal network. The network interface units perform the necessary interfacing between the external and internal networks, and make the entertainment services available to all terminals connected to the internal network. Set-top electronics that are separate from the network interface units connect to the internal network and convert the information in the digital data stream for display, by a television, for example.

Patent CA-2240786-A1 (CA)
Title: Viscous oil recovery using steam in horizontal well
Inventor: LESAGE ROBERT P
IPC: E21B43/24
Filed: 1998-06-16
Abstract: A method for recovering viscous oil from a subterranean formation through a wellbore having a horizontal section into the formation. Steam is circulated through the horizontal section to initially heat the formation and to produce fluids to the surface.      After the initial heating is complete, production is ceased while the injection of steam is continued to accumulate a slug of steam within and around the horizontal section. The well is then shut-in and the formation is allowed to "soak". Production is then resumed and steam is again continuously injected into the well when oil appears in the produced fluids. This cycle is repeated until the production of oil drops belows an acceptable rate.

Patent CA-2254295-A1 (CA)
Title: Resin applicator
Inventor: KENNEDY MATTHEW GORDON CHARLES
IPC: B05C17/005
Filed: 1998-11-30
Abstract: The invention is an applicator used to fill in the edges of composite panels with resin or emulsions. The applicator is attached to a pressurized canister filled with resin that forces the resin through the applicator's channel, then through a slot in its base. The sidewalls of the applicator guide the applicator along the edge of the panel as it is drawn along to fill the edge and also prevent spill over.  The flat, aft-end of the base of the applicator acts as a spatula to smooth the resin flush with the panel's sidewalls. The applicator may also be used to apply adhesives to the edges of solid panels.
Patent CA-2258103-A1 (CA)
Inventor: BENHAM VICTOR
IPC: G02B6/30
Filed: 1999-01-11
Abstract: A method of attaching and aligning optical fibers to integrated optical waveguide circuits of different modules is disclosed. In accordance with the method, a layout of a certain number of parallel grooves along with a number of markers, with standard distances from each other, first are imprinted on the substrate; grooves with the desired depth are then fabricated by the suitable means and fibers are embedded and affixed by the suitable adhesive in the in end-to-end grooves, fabricated in a substrate, and annealed thereafter. In one preferred embodiment, the embedded fibers are buried in the grooves such that the outer surface of the fiber is slightly below the surface of the substrate. At least one strip from the at least one side of the substrate with embedded fiber therein protruding loosely beyond the edge of the strip is cut and the end face is polished for later re-attachment. The remaining area, with embedded fiber therein, is called the "Integrated Optical Board," (IOB). The area(s) allocated for the optical waveguide circuits on the IOB is carved out and polished at the same time with a dicing saw such that the cut surfaces of the formed input/output fibers are fully exposed. The created hollow space is next filled with layer or layers of a desired material to form the lower cladding and core area for the waveguide circuit. The surface level and thickness of the said layers will match the cladding and core section of the embedded fiber. Next is to imprint or fabricate the replicate of the integrated optical waveguide patterns on the formed new substrates in the carved areas with an associated method of fabricating waveguide on that particular material. If necessary, waveguides are fabricated using direct lithography to achieve high quality waveguides with perfect alignment of waveguides with embedded fibers by means of the said markers. The said cut at least one strip of the substrate, called connector, then will be re-attached to the said Integrated Optical Board to achieve a complete attachment of the loose fibers to the board. The method offers a precise alignment and connection of the outside world optical fibers with respect to the optical waveguide without using an expensive aligning device. The method also provide a solution for integration of fiber based devices with planar waveguides. Furthermore, it provide a method of interconnecting different integrated optic circuits made of different materials.
