Patent CA-2422881-A1 (CA)
Title: Human anti-epidermal growth factor receptor single-chain antibodies
Inventor: BONNER JAMES ALAN
IPC: A61K45/00
Filed: 2001-10-12
Abstract: Human anti-epidermal growth factor receptor (EGFR) single-chain antibodies (scFvs) were isolated from a human IgM phage display library using purified epidermal growth factor receptor as antigen. Two isolates with different ami no acid sequences were identified by ELISA as epidermal growth factor receptor- specific. the scFvs bind to the full length epidermal growth factor receptor  and the truncated and/or mutated epidermal growth factor receptor on human cells. These anti-EGFR-scFvs are useful as therapeutic and/or diagnostic agents.

Title: Affichage 3d
Inventor: SLINGER CHRISTOPHER WILLIAM
IPC: G03H1/16
Filed: 2001-11-06
Abstract: L'invention concerne un procédé d'affichage d'hologrammes synthétiques à diffraction spécifique consiste à fournir une nouvelle table de diffraction modifiée de manière à stocker une frange décodée complète pour chaque point pouvant être projeté dans le volume d'image. Lors de la génération d'hologrammes synthétiques à diffraction spécifique, la table de diffraction contient des données en rapport avec l'image à projeter. L'art antérieur permet de stocker dans la table de diffraction un ensemble de vecteurs hogels (ensemble de pixels holographiques) utilisés afin de sélectionner un ensemble de franges de base en rapport avec chaque point à afficher sur l'hologramme synthétique. Ce qui signifie que chaque frange de base correspondant à un vecteur hogel particulier doit s'accumuler aux autres avant qu'une frange complète ne soit produite. Selon cette invention, le calcul préalable des franges réduit considérablement les exigences de traitement en ligne de production d'une image, étant donné que la nouvelle table de diffraction peut être produite hors ligne sans connaissance de l'image à afficher.

IPC: F16L19/02
Filed: 2003-10-17
Abstract: A metal ring gasket for a threaded union provides a high-pressure, fluid-tight, metal-to-metal seal between subcomponents of a fluid conduit. The metal ring gasket is made of carbon steel or stainless steel depending on a composition of the fluid to be conveyed through the conduit. The metal ring gasket has beveled corners and is received in a beveled annular groove on mating surfaces of the subcomponents of the threaded union. When compressed in the annular groove between the subcomponents, the metal ring gasket creates an energized, high-pressure, fluid-tight seal that is highly resistant to pressure and is capable of maintaining a seal even at elevated temperatures resulting from direct exposure of the fluid conduit to fire.

Abstract: A system and method for representing a very large dataset that enables a plan manager to define, based upon an organization modelling object, a delegation modelling object for a very large dataset. A very large dataset delegation of multiple subplans is created whose subplans can then be individually filtered for specific size restrictions. This enables a plan manager to filter the definition of each subplan prior to the execution of the delegation modelling object, precluding any need for higher-level subplans to contain a ll the data contained in their subordinate subplans. This allows subplans to contain increased levels of detail not included in their superior subplans, detail that will instead only be summarized in higher-level subplans. A subsequent consolidation process will then extract data not found at higher levels from each delegated subplan, and return that data to its original dataset.</SDOAB >
