Patent CA-2176316-A1 (CA)
Title: Apparatus for making graphic products having a platen drive with encoded sprockets
Inventor: GUCKIN MARK
IPC: B41J11/04
Filed: 1996-05-10
Abstract: A thermal printing apparatus for printing graphic images on sheet material, such as a vinyl sheet, utilizes a platen drive to move the sheet material between a roller platen and thermal print head. The thermal print head presses the sheet material into engagement with the roller platen along a linear zone of contact, and a drive motor is drivingly connected to the roller platen through a series of drive gears to rotatably drive the roller platen, and in turn move the sheet material between the platen and print head. A pair of registration sprockets are mounted on opposite ends of a common sprocket shaft, and engage corresponding feed holes formed in the marginal edges of the sheet material. The registration sprockets guide and steer the sheet material as it is driven between the roller platen and the print head, and substantially prevent buckling or like distortion of the sheet material. A sensor is coupled to the drive shaft, and generates signals indicative of the rotational position and direction of the registration sprockets, and thus indicative of the position of the sheet material relative to the print head. A controller is coupled to the sensor, and selectively energizes the heating elements of the thermal print head in response to the positional signals transmitted by the sensor and image data to accurately print graphic images on the sheet material.

Patent CA-2186691-A1 (CA)
Title: Articulated bit-selector coring tool
Inventor: HAESSLY JOHN
IPC: E21B49/06
Filed: 1996-09-27
Abstract: A multiple coring bit tool and method for taking multiple core samples of a formation traversed by a borehole in one well logging run. In this tool, multiple coring bits are used to cut the core samples. One bit is used to cut each sample. Once the core sample has been taken, the cutting bit containing the core sample is stored. For the next core, a new cutting bit is used and that cutting bit contains that core sample once the coring process is completed. Multiple cutting bits are held in two or more chambers prior to use in the coring process. The bits in one chamber are used to cut core samples from formation location above a certain hardness and the bits in the second chamber are used to cut cores in formations below a certain harness. Two other chambers are incorporated in the tool for storage of the cutting bits once the core sample has been obtained. The sequence of the sample is tracked thereby permitting the identification of any core sample and the location in the formation from which the core sample was taken.
Patent CA-2188343-A1 (CA)
Title: Horizontal inflation tool selective mandrel locking device
Inventor: BROOKS ROBERT T
IPC: E21B33/124
Filed: 1996-10-21
Abstract: A straddle tool is disclosed which ensures sequential setting of the packing elements through the use of lost motion mechanisms. Once the lower pack-off has been set, the upper one is set and an internal valve is opened to allow flow through the tool to actuate a downhole tool, such as an inflatable packer. An anchor prevents actuation of the pack-off tool unless it is extended into a profile for support of the tool. Inadvertent settings of the pack-off tool are prevented, such as in oversized casing where the anchors are already fully extended, by virtue of a distance-sensing mechanism on the tool. When a large distance is sensed by one or more sensors, the mandrel is locked to the setting collars, preventing relative movement which could set the pack-off elements.

Title: Slurrying oil sand for hydrotransport in a pipeline
Inventor: MCTURK JIM
IPC: B01F3/12
Filed: 1997-01-21
Abstract: A mixer circuit, in the form of a vertically oriented stack of components, functions to slurry oil sand with water in preparation for pumping through a pipeline. The oil sand is initially dropped from the end of a conveyor. It is contacted in mid-air with a stream of water to distribute the water through the oil sand and to wet the latter. The mixture drops into a downwardly slanted trough. The water and oil sand mix as they move turbulently through the open-ended trough. The slurry is deflected as it leaves the trough and is spread in the form of a thin sheet on an apron. It is then fed over screens to reject oversize lumps. The screened slurry drops into a pump box. The rejected lumps are comminuted in an impactor positioned at the end of the screens. The comminuted oil sand is screened to remove remaining oversize lumps and the screened comminuted oil sands are delivered into the pump box. The structure is compact and the oversize reject loss is relatively low.

Title: The treatment of autoimmune disease using 2-amino purine derivatives
Inventor: EXLEY RAY W
IPC: A61K31/52
Filed: 1995-12-15
Abstract: A method for treating autoimmune disease, or the pain and/or insomnia associated with autoimmune disease, in a mammalian subject, particularly a human, which method comprises administering a therapeutically effective amount of certain 2-amino purine compounds to the subject. The compounds particularly useful are antiviral compounds exemplified by acyclovir, valacyclovir, penciclovir and famciclovir.  The compounds are administered at doses significantly higher (4 to 12 times) than the dose level currently approved and used to treat currently recognized manifestations of viral infections. Currently approved doses result in blood levels of about 0.5-1.0 micrograms/ml.  This new technique results in blood levels of about 3-10 micrograms/ml with about 6 micrograms per ml being optimal.

Patent CA-2229657-A1 (CA)
Inventor: CAMPBELL KEITH HENRY STOCKMAN
IPC: A61K35/54
Filed: 1996-08-30
Abstract: A method of reconstituting an animal embryo involves transferring a diploid nucleus into an oocyte which is arrested in the metaphase of the second meiotic division. The oocyte is not activated at the time of transfer, so that the donor nucleus is kept exposed to the recipient cytoplasm for a period of time. The diploid nucleus can be donated by a cell in either the G0 or G1 phase of the cell cycle at the time of transfer. Subsequently, the reconstituted embryo is activated. Correct ploidy is maintained during activation, for example, by incubating the reconstituted embryo in the presence of a microtubule inhibitor such as nocodazole. The reconstituted embryo may then give rise to one or more live animal births. The invention is useful in the production of transgenic animals as well as non-transgenics of high genetic merit.
