Patent CA-2391420-A1 (CA)
Title: Implant delivery device
Inventor: DORN JUERGEN
IPC: A61F2/95
Filed: 2000-11-13
Abstract: Disclosed is a system for delivering self-expanding stents to stenting sites within the body, which minimises trauma to the affected tissue of the patient yet, at the same time, offers the medical practitioner a robust and simple system for stent placement.  These technical effects are achieved by providing a catheter which receives the stent at its proximal end and guides it to the stenting site. The catheter serves as a guide catheter and has a tapered distal tip from which the stent emerges at the site of stenting. A stent pusher can be used which abuts the proximal end of the stent inside the guide catheter. The tapered tip can be molded and cn be integral with the catheter shaft or bonded to it. The guide catheter can include a figurated portion towards its distal tip. The system has particular application to stenting the carotid artery.

Title: Sealing system for cyclone leg
Inventor: FURTADO RAMOS JOSE GERALDO
IPC: B04C5/26
Filed: 2000-12-08
Abstract: A system for sealing the leg of a cyclone for separating out solids in gas/solid suspension is described. More specifically, the present invention relates to a system for sealing the legs of two stages of cyclones in series used in fluid catalytic cracking (FCC) processes, comprising a terminal configuration which makes use of a long-radius curve (31) which is devoid of moving parts, which changes the flow direction of the descending mass flow of catalyst in dense phase into a plane orthogonal to the ascending gaseous flow, which prevents the entry of gaseous phase inside the leg (24), and which promotes efficient sealing and preventing the "packing-down" of the dense bed of particulates.

Title: Method and apparatus for producing foam
Inventor: BUREAUX JOHN
IPC: A62C35/02
Filed: 2001-05-11
Abstract: Foam carrying a decontaminating/oxidizing agent is produced by introducing air under pressure into a pair of tanks (10, 11) carrying a foam forming solution and a solution of the agent. The tanks (10, 11) are connected to an air passage (2) through a manifold (1) for introducing the foam solution and then the agent solution into the air passage (2) to produce foam bubbles coated with agent for discharge under pressure through a hose (19) connected to said air passage (2).

Title: Interface en langage naturel
Inventor: HSU CHENG
IPC: G06F17/30
Filed: 2001-05-21
Abstract: L'invention concerne une interface en langage naturel offrant une véritable fonction d'interrogation naturelle pour les utilisateurs de bases de données d'entreprise, grâce à son potentiel d'interprétation de chaque style d'expression et d'apprentissage auprès des utilisateurs pour améliorer l'efficacité. Le concept utilisé repose sur la recherche et l'apprentissage, reconnaissant le principe d'énumération-évaluation implicite comme paradigme de solution de base pour résoudre le problème des interrogations en langage naturel. Dans ces conditions, on utilise un dictionnaire de référence qui intègre les métadonnées d'entreprise (modèles d'information et connaissances contextuelles) aux raisonnements de cas particuliers. On affecte ainsi deux fonction vitales: (1) la production de toutes les interprétations possibles d'une interrogation naturelle appropriée à l'évaluation, et (2) la réduction de la complexité et de la croissance des mots clés. Selon un aspect, on utilise un dictionnaire de référence pour chercher une solution optimale, et le dictionnaire "apprend" avec l'expérience, atteignant un niveau naturel maximum avec une énumération minimum. Par rapport aux approches classiques, on débouche sur des solutions réalistes et complètes car le dictionnaire de référence et le potentiel d'apprentissage permettent de progresser dans ce sens. Plus largement, on s'aperçoit que le problème de ce type d'interface est essentiellement un problème de recherche, et on choisit comme terrain de résolution le vaste registre de l'optimisation contrainte (par exemple, problème du voyageur de commerce également chargé de l'ordonnancement). On peut donc résoudre ledit problème par le biais d'algorithmes limités, en évitant les permutations exponentielles de mots clés.

IPC: H04M15/00
Filed: 2001-05-23
Abstract: The invention relates to a method and a system implementing the method for arranging subscriber billing in a multi-provider environment wherein a subscriber desiring a service uses both a first network (A) and a second network (T). In order to bill the subscriber, either a tariff of the second network (T) is transmitted to the first network (A), a tariff of the first network is combined with the tariff of the second network and the subscriber is billed according to the combined tariff, or a billing identifier is generated in the first network (A) to be transmitted to the second network (T), the billing identifier is attached to billing information in both networks and the pieces of the billing information that comprise the same billing identifier are combined in order to bill the subscriber. The invention thus enables a subscriber in a multi-provider environment to be billed using a single bill.
