Patent CA-2150061-A1 (CA)
Title: Method and means for processing images
Inventor: DICKINSON ALEXANDER GEORGE
IPC: H04N1/21
Filed: 1995-05-24
Abstract: An  image  of  an  object,  such as  message  for facsimile transmission,  is acquired optically by setting photosensitive  cells  along a multiplicity of  rows  and columns of a random access memory to a given value such as 1, exposing the plurality of cells to an image so the cells change electrical values to exposure values, and after a given time, ending the effective exposure by maintaining values in the cells corresponding to the exposure content of the cells.  The maintaining involves going in sequence from row to row, and in each row simultaneously reading the cells in the row and, on the basis of the reading, writing refresh values representative of the exposure values back into the read cells of the row, and repeating the row to row sequence cyclically to prevent changes in the cells due to further exposure.  The refreshed data is processed by sequentially reading the refresh values of the cells of a column serially from column to column until  all  the values have been processed.  Processing includes transmission, or compression and transmission.

Title: Improvements in automatic vehicle location systems
Inventor: PEARCE JOHN NICHOLAS
IPC: G08G1/123
Filed: 1994-05-06
Abstract: An automatic vehicle location centre comprises a control centre (2) and a plurality of mobile units (12). Each mobile unit is able to derive a current position signal from external radio signals. A prediction (22) is responsive to this current position signal and to predicted motion of the mobile unit to derive a predicted position signal. The predicted and current position signals are compared and the current position signal is transmitted to the control centre in dependence on the result of the comparison. The control centre (2) has a predictor (10), similar to that in each mobile unit, responsive to the current position signal and to predicted motion of the mobile unit to derive a predicted position. This position data is only transmitted from a mobile unit to the control centre if the predicted position signal differs significantly from the actual position.

Patent CA-2171178-A1 (CA)
Title: Tool for maintaining wellbore penetration
Inventor: LABONTE RAYMOND C
IPC: E21B19/08
Filed: 1994-10-12
Abstract: A tool for connection in a wellbore drill string for maintaining penetration of a drilling bit attached to the drill string when the drill string becomes stuck or hung up during drilling operations.  The tool has a telescoping outer member (20) and inner member (22) which form an annular chamber (64) between them which contains a plurality of springs (84) that are selected to provide a desired amount of contraction of the tool when a predetermined axial compressive load is applied through the tool to the drilling bit.  The tool also includes interlocking splines (81, 83) on the outer member and the inner member (20, 22) which inhibit rotational movement of the outer member and inner member relative to each other, and the chamber (64) is filled with hydraulic fluid which is pressurized to the hydrostatic pressure of the wellbore adjacent the tool by a floating piston (92) which is movably located in the chamber (64).  In operation, the tool contracts when an axial compressive load is applied through the tool during drilling operations.  If the axial compressive load is decreased due to sticking or hang up of the drilling string, the springs operate to extend the tool, thus maintaining a force on the drilling bit which causes the drilling bit to maintain an amount of penetration in the wellbore.

Patent CA-2172048-A1 (CA)
Inventor: BUISSON GERARD LAURENT
IPC: B05B11/00
Filed: 1994-09-20
Abstract: The present invention pertains to improved manually operated atom-ization systems which combine atomizing nozzles with high pressure, pre-compression type pump mechanisms in order to provide a consistent, high quality, finely-atomized spray of a comparatively higher viscosity fluid. The pre-compression pump mechanism ensures that the product will only be de-livered when sufficient pressure is available for atomization regardless of the speed or authority with which the pump mechanism is actuated. When the fluid is discharged from the nozzle in a swirling, conical film, the fluid is broken up into a finely-dispersed mist which may then be directed toward the surface to be coated. Pump mechanisms for use with the present invention incorporate specific design features which facilitate the flow of comparatively viscous fluids with reduced flow resistance and hence reduced pressure losses, as well as providing enhanced structural integrity to better withstand such op-erating pressures and forces while providing improved reliability. The com-bination of pre-compression and comparatively higher operating pressures ensures that the comparatively higher viscosity fluid will be delivered to the nozzle with a pressure (and hence a velocity) that is comparatively high and within a comparatively narrow range. This in turn ensures a finely-dispersed product spray with a comparatively narrow range of particle sizes, under a wide range of actuation circumstances.

Title: .alpha.-glucosidase inhibitor, composition principally comprising sugar and containing the same, sweetener, food and feed
Inventor: TSUKADA MASAYUKI
IPC: A23L27/30
Filed: 1996-04-19
Abstract: This invention relates an .alpha. -glucosidase inhibitor mildly inhibiting .alpha. -glucosidase locally present in the micro-villus of small intestine, a composition principally comprising sugar and containing the inhibitor, a food, a sweetener and a feed.  The inhibitor delays the digestion of starch, starch-derived oligosaccharides and sucrose, so that the inhibitor has an action of suppressing rapid increase in blood glucose level and an action of suppressing insulin secretion at a lower level.  Thus, the inhibitor is useful for the prophylaxis of obesity and diabetes mellitus. The .alpha. -glucosidase inhibitor of the present invention is composed of nucleotide, nucleoside, or base as the structural component of nucleic acid and one or two or more digestible sugars selected from sucrose, starch and starch-derived oligosaccharide.  The .alpha. -glucosidase inhibitor mildly inhibits the action of .alpha. -glucosidase as a digestive enzyme in small intestine, and has effects of suppressing rapid increase in blood glucose level and suppressing insulin secretion at a lower level.  In combination with digestible sugar, the .alpha. -glucosidase inhibitor is applicable as food, sweetener and feed.
