Patent CA-2133874-A1 (CA)
Title: Method and system for automatic formatting of user selected text
Inventor: MASON CHRISTOPHER A
IPC: G06F17/24
Filed: 1994-10-07
Abstract: A method and system for automatic formatting of user selected text in a word processing system. A number of format options are displayed to the user and a text format selection is then obtained from the user for a selected format option. An identifier identifying the selected text format is stored in a text format data structure. One or more portions of existing text are thereafter selected by the user. For each selected portion of existing text, the selected portion is formatted with the text format identified by the identifier stored in the data structure. These steps are repeated until canceled by the user or until the user enters new text. In a preferred embodiment, the word processing system provides a conventional mode for performing conventional text formatting in which a text format is specified only after a single portion of existing text is selected by the user to which to apply the specified text format. The word processing system also provides an automatic formatting mode for automatically formatting any number of selected portions of text with a selected text format, as described above. By selecting a text format without first selecting a portion of existing text to which to apply the selected text format, the user places the word processing system in automatic formatting mode. Canceling the selected text format or entering new text converts the word processing system back to the conventional mode.

Patent CA-2135538-A1 (CA)
Title: Powder Transfer from Supersack Containers and Dispersion Into a Homogeneous Slurry
Inventor: WALKER RICHARD C
IPC: B65B69/00
Filed: 1994-11-10
Abstract: Apparatus and with a horizontally stretched flexible membrane is used to sealingly support a lower, openable end portion of an air-permeable sack containing powder material.  A conical funnel-like sealable portion of the apparatus  immediately  beneath  the  membrane  may  be connected to a mechanism for applying a suction.  This suction uses inward air flow from the ambient atmosphere through the air-permeable wall of the sack and the powder material  contained therein,  to generate a  fluidized air/powder material outflow from the lower opening of the sack.   The funnel-like element guides this flow and enables transfer of the air-fluidized powder material flow.  To form a slurry, a conventional disperser/mixer mechanism dipped into a quantity of liquid in a tank may be connected to a suction duct to apply the desired suction.   Fluidized air/powder material flow then is intensely and rapidly stirred with the liquid to form a slurry.

Title: Method and system for fast microscanning
Inventor: CHEVRETTE PAUL
IPC: H04N5/225
Filed: 1994-12-28
Abstract: An imaging system for implementation of a microscan includes an array of sensing elements that define an image plane. A movable lensing system is adapted to focus an image on the image plane. Piezoelectric positioners are provided to move the lensing system a predetermined amount and on a predetermined plane parallel to the image plane so that the image focused by the lensing system on the array of sensing elements is displaced on the image plane by the movement of the lensing system. As the lens is moved by the positioners and thus the optical axis of the lens, the image passing through the lens is also moved on the image plane. Moving the lens back and forth or in a predetermined pattern provides dithering of the image so that microscanning can be employed.

Patent CA-2149132-A1 (CA)
Title: Specifically crosslinked hemoglobin with free functionality
Inventor: KLUGER RONALD
IPC: A61K47/48
Filed: 1993-11-12
Abstract: Hemoglobin is site-specifically crosslinked into its tetrameric form by reaction with a trifunctional reagent which combines electrostatic effects, steric effects and the presence of functional groups so that two of the functional groups react with specific sites on the hemoglobin whilst the third site is left free for reaction with endogenous nucleophilic compounds. A specific example of such a crosslinking reagent is trimesoyl tris(3,5-dibromosalicylate), TTDS, which effects specific crosslinking between the amino groups of lysine-82 on each respective .beta. sub-unit. While the crosslinking reagent TTDS has three available carboxyl groups for the crosslinking reaction, only two so react, leaving one free carboxyl for reaction with exogenous nucleophiles, e.g. to render the hemoglobin product useful as a carrier for nucleophilic compounds through the body's circulatory system.

Spaced longitudinal slits are formed in the seam zones, the slits permitting the fabric to envelope the tubes.
Patent CA-2155896-A1 (CA)
Inventor: LEE CHEUK YIN MARTIN
IPC: B60N2/02
Filed: 1995-08-11
Abstract: The present invention relates to a mechanism for more convenient seat adjustments on some automobiles. Both the manually operated type and the power-assisted type have drawbacks: the former does not provide memory functions and the latter leads to significant increases in production cost and vehicle weight. The present invention provides memory functions at a lower cost and with little weight increase, enabling the user to adjust the seat to his/her most comfortable configuration easily and quickly. The essence of the present invention is that the mechanism will not allow further adjustments of, for instance, the angle of the back of the seat if the angle is the same as that of the selected pre-set seat configuration.

Patent CA-2173256-A1 (CA)
Title: An expanding method and a tool therefor
Inventor: SOERBERG BENGT
IPC: B21D41/02
Filed: 1994-10-07
Abstract: When expanding a pipe-end (1), there is used a tool which includes a plurality of jaws (8) that can be moved radially in relation to a centre axis (11), between a retracted position and an outer expanding position.  The jaws are inserted to a given distance in the pipe-end (1) with the jaws in their retracted position.  The jaws have outer surfaces (12) which lie adjacent one another in the retracted positions of the jaws and have a circular-arcuate shape in cross section for engagement with the inner surface of the pipe-end.  The radial distance (22, 23) of the outer jaw surfaces (12) from the centre axis (11) increases from the insertion end (20) of the jaws to their opposite end (21).  The pipe-end is expanded successively in several stages with relatively small jaw movements, wherein the jaws (8) are retracted and inserted further into the pipe-end between each expansion stage.  The jaws (8) of the tool can be moved radially through a distance which is smaller than the ultimate radial expansion of the pipe-end (1).

Title: Mill warp controlling method and device in a metal band casting plant
Inventor: VENDEVILLE LUC
IPC: B22D11/10
Filed: 1996-04-03
Abstract: Casting device for a metal strip (9) where the solidification is effected by passing the molten metal between two counter rotating rolls (1,1') on horizontal axes. The rolls (1,1') are cooled by the internal circulation of a cooling fluid and the roll gap defines the casting space (2) for the molten metal. The outer surfaces (3,3') of the rolls have a specified roughness. The casting space (2) is rendered inert by blowing a given quantity of a gas or gas mixture across a cover (10) covering the casting space (2). The camber of the rolls (1,1') is regulated by changing the quantity of injected gas and/or the nature of the gas or the composition of the gas mixture, at least around the surface of each roll upstream of the contact zone with the molten metal. Also claimed is device (14,15,16) for blowing the gas and a system (7,18,19,20,21,22,22',23,23',24,24') for modulating the quantity of gas injected and/or the nature of the gas or the composition of the gas mixture. The gas mixture used may be a mixture of nitrogen and argon.
