Patent CA-2150907-A1 (CA)
Title: Immunoassay
Inventor: TRELOAR PAUL HOWARD
IPC: G01N33/58
Filed: 1993-12-03
Abstract: Electrochemical immunoassay methods are disclosed.  In one method, a membrane is provided between the sample and the detecting electrode.  The membrane is such that it will allow passage therethrough of unbound labelled analyte (but not its complex with antibody).  The unbound labelled analyte, which is electrochemically active, may then be detected at the electrode.  In a further method, the electrochemical immunoassay uses a labelled analyte which is both fluorescent and electrochemically active.  This allows optimisation of the electrochemical immunoassay.
Patent CA-2151329-A1 (CA)
Title: Method of seam closure for sheet transfer and other paper processing belts
Inventor: MILLER LAWRENCE G
IPC: D21F3/02
Filed: 1995-06-08
Abstract: Methods for closing a seam in a paper processing belt having a coating of polymeric resin material require the covering of the seam on the uncoated side of the belt with an encapsulating material, so that the seam will have compression properties substantially identical to those of use of the remainder of the belt. In one method, a viscous paste obtained by mixing a polymeric resin material with a blowing agent is used. Following installation of the fabric, or belt, on a paper machine by closing its pin seam with a pintle, the seam region on the non-paper side of the fabric or belt is impregnated with the viscous paste. The seam region is then heated to a temperature to activate the blowing agent and to create a foam from the paste. The foam fills voids in the seam region, and may pass out through the slit in the coating over the seam. Raising the temperature further cures the foam and may glue the slit closed. In other methods, a pre-foamed polymeric resin may be used to impregnate the seam region, or the seam region may be covered with a solid foam strip of a polymeric resin or a fibrous strip of fibrous batt material, either of which may be secured to the seam region by an adhesive. In each case, the belt so seamed may be used as a transfer belt or long nip press (LNP) belt, or in other paper processing applications.

Patent CA-2154451-A1 (CA)
Inventor: WISHNIE JEFFREY
IPC: G06F17/21
Filed: 1994-01-03
Abstract: An innovative system and method provide a cursor tool framework and tool server with support for multiple cursors on any given system, and supports the selection of a cursor tool utilizing a cursor. The framework and server facilitate the association of cursor tools to a cursor in a process independent space such that tools can be used cross-process and cross-document. The framework also provides default functionality for communication and negotiation among cursor tools and the canvas on which they are used. This negotiation allows any cursor tool and any document to function together such that the cursor tool can be written without the knowledge of the document developer. The framework provides implementation for the distribution of cursor tools across processes and documents in an efficient manner such that documents need not be aware of tools until such time as the tool has successfully negotiated with the document for the right to alter the documents data.

Title: Method and System for Managing Memory in a High Speed Network
Inventor: JOHNSTON CESAR AUGUSTO
IPC: H04L12/56
Filed: 1994-11-29
Abstract: A method and system are provided for managing memory to reassemble data packets received from different virtual channels in an ATM network. The method and system recognizes that both reliable and best effort traffic must be supported by a network interface. The system makes use of a virtual First-In-First-Out (FIFO) concept that partitions random access memory (RAM) space into multiple FIFO queues. The virtual FIFOs can have different sizes, and can be allocated to connections depending on quality of service requirements. A  dedicated embedded controller (721) to provide flexibility is used in the system, as well as Content Addressable Memory (CAM) devices (723, 724) and external logic. The method and system can also be applied at ATM transmitters in the implementation of congestion control algorithms.

Abstract: Un système de reproduction d'images animées par communications bidirectionnelles, dans lequel des personnages et des graphiques sont séparément codés de manière à reproduire des images de haute qualité. Un serveur vidéo transmet les codes cinématographiques de la vidéo désirée à un terminal en réponse à une demande du terminal. À ce moment, en vérifiant un fichier d'informations d'enregistrement de terminaux, il est décidé si oui ou non une matrice de pixels des personnages et des graphiques stockés dans la région de l'utilisateur des codes cinématographiques est enregistrée dans le terminal. Lorsque les données d'image matricielle ne sont pas enregistrées dans le terminal, les données d'image matricielle sont transmises au terminal par un encodeur d'image matricielle. Le terminal lit les codes d'image matricielle stockés dans la région de l'utilisateur des codes cinématographiques et reproduit les données d'image matricielle dans le décodeur d'image matricielle. Un codage optimal peut être effectué et une taille de code peut être compressée davantage.

Title: Tumor suppressor genes, proteins encoded thereby and use of said genes and proteins
Inventor: KIMCHI ADI
IPC: C12Q1/68
Filed: 1994-10-12
Abstract: The present invention is based on the pioneering finding that inhibition of expression of certain genes counteracts the cytokine-induced cell death. As long as these genes function normally, cytokine induces cell death; once the expression of said genes in inhibit, the cytokineinduced cell death is inhibited. It follows therefrom that the normal expression is cytokine-induced cell death. In HeLa cells IFN-y induces a biphasic process, which comprises an initial cytostatic phase and a subsequent cytotoxic phase (programmed cell death). The novel genes discovered in accordance with the present invention were found to affect only the later, cytotoxic phase. These genes, referred to as "DAP" (death-associated protein) genes, include DNA molecules which comprise a coding sequence encoding the expression products of the DAP genes or expression products having a similar biological activity, and are at times collectively referred to as "DAP DNA molecules". The expression products of the DAP DNA molecules will be referred to herein at times collectively as "DAP products".
