Patent CA-2321741-A1 (CA)
Title: Method of particle formation
Inventor: HUMPHREYS GWYNFOR OWEN
IPC: B01D11/02
Filed: 1999-02-26
Abstract: A method for forming particles of a substance, comprising: (a) preparing a solution or suspension (6) of the substance in a vehicle; (b) introducing the solution or suspension into a particle formation vessel (1) via a fluid inlet means (5); and (c) introducing with the solution or suspension a primary supercritical fluid (8-10) capable of acting as an anti-solvent for the substance, under conditions which allow the supercritical fluid to extract the vehicle from the solution or suspension and hence cause the formation of particles of the substance; wherein a (preferably supercritical) secondary fluid (12) is introduced into the particle formation vessel with the solution or suspension and/or the primary supercritical fluid, upstream of or at the point at which particle formation occurs, the secondary fluid (12) having a lower capacity for extracting the vehicle than that of the primary supercritical fluid. The invention also provides the use of such a secondary fluid (12) for the purpose of eliminating, at least substantially, blocking of the fluid inlet means and/or of the fluid supply line(s) to the inlet means, in such a particle formation method, and/or for the purpose of reducing pressure fluctuations in the fluid inlet means and/or fluid supply line(s).

Title: Electronic commerce system and its method
Inventor: PARTOS JEROME
IPC: G06Q20/00
Filed: 2000-12-20
Abstract: To provide an electronic commerce ofsystem and a method of electronic transaction wherein personal data of each customer is protected from being collected or stored by a party otherparty than the customer himself, andalso capable of reliably a complaint or an inquiry from a customer can reliably be responded.      Means of Attaining the Object A sales information coordinating organization is positioned between customers' terminals and sellers' terminals. The sales information coordinating organization collectively manages the personal information of all the customers. The sales information coordinating organization separately arranges the two types of information, i.e. the personal information including the names and the address of the customers, and the order information into data, and stores these different types of data in separate databases. After a transaction is completed, the sales information coordinating organization removes the personal data of the customer. The sales information coordinating organization transmits to a seller or a service organization an ID number and a transaction code attached to each customer instead of the personal information, such as, the name, the address, etc. In the event of a complaint or an inquiry from a customer, too, the sales information coordinating organization comes between the customer and the seller or the service organization and conveys the customer's request to the seller or the service organization.

Abstract: An "immersive experience" motion picture theatre is provided either as a purpose-built structure or as a "retro-fit" of an existing domed theatre. The theatre of the invention has an audience seating deck (20) which slopes downwardly towards a screen (22) of part-cylindrical shape. The screen slopes upwardly and extends above the seating deck as well as wrapping around the sides of the seating deck. A projector (26) located within the seating deck (20) projects images onto the screen (22) about an upwardly oriented projection axis, through an orthographic fisheye lens which minimizes distortion of centre regions of the images. In this way, motion pictures that have been shot for showing on domed screens can be successfully projected onto the curved screen (22) of the invention.

Title: Method for evaluating measurement error in coordinate measuring machine and gauge for coordinate measuring machine
Inventor: SHIBATA MASANORI
IPC: G01B3/30
Filed: 2001-01-22
Abstract: A gauge for a coordinate measuring machine has a plurality of balls whose centers are located on at least one line inclined with respect to a reference axis in a virtual reference plane. The gauge is set on a measuring table of the coordinate measuring machine. Orthogonal coordinates in which one of the coordinate axes is identical to the reference axis are set in the virtual reference plane. The coordinates of the center of each ball are measured by the coordinate measuring machine.  Thereafter, the gauge is turned and inverted by 180 degrees about the reference axis and is set again on the measuring table. Orthogonal coordinates in which one of the coordinate axes is identical to the reference axis are set in the virtual reference plane.  The coordinates of the center of each ball are measured in the same way as above.  Thus, measurement errors of the straightness of the machine ares of the coordinate measuring machine and the orthogonality between the machine axes can be easily and precisely evaluated.

Abstract: A wiper assembly for cleaning a windshield while supplying cleaning fluid thereto, comprising the usual motor-driven reciprocating arm, and a wiper member in the form of an elongated hollow body having fluid passages therein extending from a inlet to an outlet. The hollow body has an inner side for contacting a windshield and which is open so that fluid within the passages can contact the windshield, while peripheral wiper blades restrict flow of fluid along the windshield and out of the body, beyond the blades. A supply conduit leads from a pumped supply of cleaning fluid to the hollow body inlet, and an outlet conduit leads from the outlet to a reservoir, so that fluid which has entered the hollow body through the inlet and has served to clean the windshield can pass through the outlet conduit back to the reservoir, without passing into the environment.

Abstract: A method for manufacturing a dimensionally stable composite cellulosic product having side and edge surfaces involves applying a sheet of thermoplastic material to at least one side surface of the composite product. Pressure and heat are applied for a pre-determined period via a heated press to melt the thermoplastic material to bond to and coat the at least one side surface of the product. The resulting product enjoys significantly improved dimensionally stability when exposed to water. Thickness swelling of the coated product is reduced by over 70% as compared to a conventional composite cellulosic product without the coating. In the case of oriented strand board (OSB) manufactured according to the method of the present invention, thickness swell of 2-5% after 24 hour water soaking is observed as compared to 10-15% swell with conventional OSB.
