Patent CA-2338581-A1 (CA)
Inventor: KREUTZER KRISTINA ANN
IPC: C08F4/64
Filed: 1996-01-24
Abstract: Disclosed herein are processes for polymerizing ethylene, acyclic olefins, and/or selected cyclic olefins, and optionally selected olefinic esters or carboxylic acids, and other monomers. The polymerizations ate catalysed by selected transition metal compounds, and sometimes other co-catalysts. Since some of the polymerizations exhibit some characteristics of living polymerizations, block copolymers can be readily made. Many of the polymers produced are often novel, particularly in regard to their microstructure, which gives some of them unusual properties. Numerous novel catalysts are disclosed, as well as some novel processes for making them. The polymers made are useful as elastomers, molding resins, in adhesives, etc. Also described herein is the synthesis of linear .alpha.-olefins by the oligomerization of ethylene using as a catalyst system a combination of a nickel compound having a selected .alpha.-diimine ligand and a selected Lewis or Bronsted acid, or by contacting selected S(a)-diimine nickel complexes with ethylene.

Title: Image forming apparatus and method, and image applied article
Inventor: ANDOH TOMIO
IPC: B41J2/325
Filed: 1999-08-26
Abstract: An image forming apparatus uses an ink ribbon (7) having a plurality of ink layers (72) of different colors, and a long, film-like intermediate transfer medium (6). A platen (10) for holding the intermediate transfer medium (6) during transfer is driven by a motor (50) via a synchronous reduction gear (51 - 58) whose speed reducing ratio is an integer multiple.      The ink ribbon (7) is selectively heated by a thermal head (38) having substantially regular polygonal or substantially circular heat-generating portions (38a).      Under the control of a controller (C1), the thermal head (38) is driven on the basis of image information, and a record image containing an area gradation image is formed on the intermediate transfer medium (6).      This area gradation image has a color set by stacking dots having different colors in substantially the same spot. The intermediate transfer medium (6) on which the record image is formed is overlapped on a target body (1) and heated and pressed by a heat roller (40), thereby transferring the record image from the intermediate transfer medium (6) onto the target body (1).

Inventor: PETING ROBERT G
IPC: B22D29/00
Filed: 2001-04-10
Abstract: An apparatus and method are disclosed for extracting a cast iron pipe from a centrifugal casting machine and for also breaking the continuity of an annular sand core used to form the bell end of the pipe. The apparatus has a carrier member on which are mounted extractor carries jaw assemblies and core continuity breaking members.  The extractor jaw assemblies are movable between extended and retracted positions.  One end of the carrier member is inserted into the bell end of the pipe while the pipe is in the casting machine. The extractor jaw assemblies are retracted as the carrier member enters the pipe. As the carrier member enters the pipe, the core continuity breaking members plow through parts of the sand core to break the continuity of the sand core. The extractor jaw assemblies are then extended to contact the interior surface of the pipe wall and the apparatus is retracted, pulling the pipe out of the mold in the casting machine. The sand core is broken into pieces and the chunks of the sand core fall out of the pipe. The pipe may then be processed in the normal manner.

Title: El display apparatus
Inventor: KIYOHARA ATSUSHI
IPC: G09G3/30
Filed: 2001-04-27
Abstract: A data side driving IC incorporates pull-up elements and pull-down elements to be applied with modulating voltages of +1/2VM and -1/2VM, respectively. A scanning side driving IC incorporates pull-up elements to be applied with a positive write voltage of +VW from a positive voltage supply circuit, and pull-down elements to be applied with a negative write voltage of -VW from a negative voltage supply circuit. Each data electrode is driven by a positive voltage of +1/2VM or a negative voltage of -1/2VM. Each scanning electrode is controlled so that it is applied with a positive write voltage of +VW or a negative write voltage of -VW or it assumes a ground potential or a floating potential. Since the data electrodes and the scanning electrodes can be driven with high symmetry of positive and negative polarities, the long-term reliability can be enhanced, while at the same time the peripheral circuitry can be simplified.

Title: Procede et logiciel permettant de mettre en evidence une utilisation illicite d'un systeme informatique
Inventor: SHAW GILBERT B
IPC: G06V10/40
Filed: 1999-10-28
Abstract: L'invention se rapporte à un ordinateur (10) doté d'un logiciel qui recherche certaines activités qui peuvent être illicites (par exemple, le traitement d'un fichier graphique correspondant à un billet de banque). Lorsqu'une telle activité est détectée, des données de repérage détaillant ladite activité sont produites et sauvegardées secrètement dans un ordinateur (10). Si l'ordinateur fait ultérieurement l'objet d'une recherche ou d'une saisie, les données de repérage peuvent être récupérées et utilisées comme preuve de l'utilisation de l'ordinateur à des fins, par exemple, de contrefaçons. Il est possible de mettre en oeuvre deux types d'analyse pour détecter si des données d'images graphiques correspondent à un billet de banque. L'une de ces techniques est fondée sur la détection d'un motif visible caractéristique d'un document de sécurité. L'autre est fondée sur la détection d'un filigrane numérique stéganographique, caractéristique d'un document de sécurité. Si l'une ou l'autre de ces caractéristiques est détectée, l'image est étiquetée et les étapes appropriées de lutte contre les contrefaçons peuvent être entreprises. La détection du motif visible peut être exécutée à l'aide d'une série de tests de plus en plus rigoureux. Si l'image ne satisfait pas le premier test, les tests suivants peuvent être sautés, ce qui permet d'accélérer le processus. Dans certaines réalisations, il est possible d'utiliser des techniques de reconnaissance de motif basées sur une transformée de Hough. Le fait d'équiper un unique appareil à la fois d'un détecteur de motifs visibles et d'un détecteur de filigranes permet d'accroître la fiabilité et simultanément d'assurer l'efficacité dans diverses mises en oeuvre.
