IPC: H04N5/44
Filed: 1998-02-13
Abstract: Appareil de conversion d'un signal d'image servant à convertir un premier signal d'image en un deuxième signal d'image, les premier et deuxième signaux d'image comprenant plusieurs images de cadres différents. Un détecteur de mouvement est fonctionnel et sert à détecter le mouvement du premier signal d'image entre un premier cadre et un deuxième cadre. De plus, le circuit de traitement produit le deuxième signal d'image en se fondant sur une hypothèse d'un pixel à une position correspondant au mouvement détecté. L'appareil peut être utilisé pour produire un signal de sortie soit de la même résolution que le premier signal d'image, avec un repliement de spectre réduit ou éliminé, soit d'une résolution supérieure en direction verticale ou horizontale.

Title: Soaps produced from high laurate canola oil-based fatty acids
Inventor: DEL VECCHIO ANTHONY J
IPC: C11D13/00
Filed: 1997-01-17
Abstract: Soap compositions prepared by using saponified laurate canola oils (LC-oils);  these oils resemble conventional canola oil except LC-oils contain lauric acid levels and myristic acid levels in weight percents greater than the weight percents of these fatty acids found in conventional canola oil. The LC-oils are preferably produced in vivo by genetically engineered plants. Such plants produce seeds that preferentially accumulate oils with 12:0 fatty acids. The LC-oils are used as replacement or substitution oils for coconut oils in soap manufacture. The obtained soap compositions exhibit improved foaming and mildness characteristics as compared to soaps produced with coconut oil.

IPC: E04B7/10
Filed: 1998-08-24
Abstract: A self supporting, self reinforcing system for the assembly of precisely-cut, relatively thin sheets of material such as, polycarbonate plastic, fiberglass, stainless steel, aluminum, etc.  which have had their edges folded, sealed and finally fastened together to form a curving, geodesic-like, self supporting dome structure. Such structures are used for various purposes, including storage facilities, repair shops, housing, arenas, housing, and public buildings. The laminated, joined flanges become the supporting frame. This differs with many other dome-like structures which have a common difference with the invention applied for, in that they are usually composed of a skeletal frame of various types of members, joined at hubs, and then covered by sheet sheathing, or fabric material covering the frame structure. The object of the present invention is to provide a panel system for constructing curved, geodesic-like structures of various shapes and sizes that can achieve a higher strength with a much simpler and more cost-effective construction than heretofore known.
Patent CA-2244423-A1 (CA)
Inventor: ISHIKAWA EIJI
IPC: G01N33/543
Filed: 1998-07-30
Abstract: An assay method capable of efficiently trapping an analyte in a certain amount of a reaction liquid in a short reaction time, the method being characterized in that only a part of a solid phase coated with a substance that specifically binds to the substance to be assayed is immersed in a pool of the reaction liquid containing the analyte, and this part of the solid phase is exchanged during the reaction, so that any surface of the solid phase can be immersed in the reaction liquid once in a predetermined time, and an assay kit for the assay based on this principle. In comparison with the conventional assay methods wherein the entire area of a limited solid phase surface is brought intocontact with a certain amount of a reaction liquid, or wherein a test solution is diluted to bring the entirety of a certain surface area of the solid phase into contact therewith, the inventive method can increase reaction speed, which in turn results in trapping of the analyte on the solid phase efficiently in a short time. This reaction system can be used for the detection of an enzyme label in an enzyme immunoassay.

Patent CA-2261635-A1 (CA)
Title: Methods for communication using pcm codewords
Inventor: TOWNSHEND BRENT
IPC: H04Q3/42
Filed: 1998-02-19
Abstract: A new data communication system is described which enables data transmission over existing telephone lines at rates higher than possible with existing methods, including conventional modems. By using a novel asymmetric configuration of the two communicator endpoints, the currently-accepted maximum theoretical limits on the data rate are no longer applicable. One endpoint is connected directly to a digital telephone network, whereas the other endpoint uses a conventional telephone connection. This reduces the transmission problem to compensation for a single telephone line interface and a single analog local loop. Means of providing this compensation and the required clock synchronization were also created, enabling a practical implementation of the system. The new system can achieve rates up to 64,000 bits-per-second and has broad utility in several active areas including wide-band audio transmission, video transmission, networking, facsimile transmission, and remote computer access.

Abstract: A method of fluorinating an organic compound comprising reacting an organic compound with a fluorinating agent characterised in that a perfluorocarbon compound is present in the reaction medium. The perfluorocarbon compound may replace an amount of a solvent which would otherwise be required for the reaction to proceed efficiently. The perfluorocarbon compound is readily recoverable after reaction and may be re-used in subsequent reactions. Additives to the reaction medium, such as 18-crown-6, may increase the amoun of solvent which may be replaced. The method is beneficial where solvent consumption would otherwise be large, or where solvent recovery would otherwise be difficult.

Title: Mold for use in plastic injection molding system and venting pin assembly for use therein
Inventor: MURPHY JOHN F
IPC: B29C45/34
Filed: 1999-03-11
Abstract: A mold for use in a plastic injection molding system includes a venting pin assembly which can not only vent an article-defining cavity in the mold but can also eject a formed plastic article in an open position of the mold. A porous insert of the assembly permits air from the article-defining cavity to flow there-through while preventing the passage of molten plastic from the article-defining cavity in a closed position of the mold. A venting pin of the assembly in the form of a hollow ejector pin has an elongated aperture formed therethrough to permit the flow of air therethrough.      The porous insert is positioned in the aperture at a gas hole formed through an end surface of the ejector pin.      The insert and the gas hole are sized so that the insert and the end surface help to form a "Class A" surface on the article formed in the article-defining cavity.
