Abstract: A perforating gun assembly that includes at least one component that is constructed from a composite material and that is impermeable to wellbore fluids. The components may include the outer carrier and/or loading tube of a perforating gun, the connecting tubing of a gun release mechanism, and the gun connector used to attach adjacent perforating guns. The composite material is designed to be very brittle under dynamic impact. The component is made impermeable to wellbore fluids by including an impermeable liner therein. The impermeable liner can be bonded to the inner or outer surface of the component or can be embedded within the component. Since it is brittle under dynamic impact, the composite component shatters into small pieces upon detonation of the perforating gun.

Abstract: L'invention concerne un procédé et un dispositif de transformation de haut niveau permettant de convertir des formats de données, notamment dans le contexte des applications de réseau. Un mécanisme de transformation flexible facilite la génération en temps réel d'un code d'instructions de transcodage. Un transcodeur est généré de manière dynamique par une machine de compilation de transcodeur. Dans la présente invention, cette machine de compilation de transcodeur fait appel à deux descriptions formelles de formats lisibles par une machine (FMRFD) et à une mappe de données (DMAP) correspondante afin de générer un code d'instructions naturel exécutable par l'unité centrale de la plate-forme de transcodage. Lorsqu'un train de données d'entrée est introduit dans le transcodeur, ce dernier génère un train de sortie en exécutant le code objet naturel généré en temps réel par la machine de compilation de transcodeur. Le transcodeur peut en outre être configuré de manière à pouvoir exécuter un transcodage bidirectionnel entre deux trains de données ainsi qu'un transcodage entre deux séquences de protocole distinctes.

Abstract: L'invention concerne un procédé de numérotation de paquets de données dans un système de télécommunication à commutation par paquets. Ce système est pourvu d'un protocole de télécommunication comprenant une couche de protocole de convergence destinée à adapter des paquets de données utilisateur à des paquets de protocole de convergence, ainsi qu'une couche de liaison destinée à transmettre ces paquets de protocole de convergence en tant qu'unités de données et à confirmer cette transmission. Un compteur définit des numéros de paquets de données pour ces paquets de protocole de convergence, lesquels sont transférés vers la couche de liaison et transmis sans numéro de paquet de données. Un numéro de paquet de données est également défini pour les paquets de protocole de convergence reçus au moyen dudit compteur, la réception de ces paquets étant confirmée à l'émetteur. Si la couche de liaison ne peut pas assurer une transmission fiable des paquets de protocole de convergence, l'identification des paquets de protocole de convergence perdus est transmise vers le destinataire afin de mettre à jour de la contre-valeur du destinataire, d'où une correspondance avec la contre-valeur de l'émetteur.

Abstract: A novel, one-way nut fastener including a nut body with a side wall that is internally threaded and lobes that extend from the side wall of the nut body.  Each lobe has a flat portion that extends substantially radially away from the side wall and a curved portion that extends from the flat portion to the flat portion of an adjacent lobe. A special tool uses the leverage that is gained from the flat portions of the lobes to tighten the cap threads onto the threads of a stem portion. Since the leverage gained from the lobes, which is used to tighten the nut fastener, cannot be used to loosen the fastener, it is much more difficult to remove the nut fastener.

Abstract: The invention relates to the control of leakage from ducts, such as fluid-carrying pipework, without necessarily requiring direct access to the leakage site itself; since leakage sites are often difficult to locate with the necessary degree of precision to permit access to reliably be made thereto, and moreover, even if a site can be located, it is not always convenient or economically possible to secure access thereto. The invention provides an apparatus and methods for duct leakage control wherein a sealing element (1) is introduced into the duct and is automatically drawn or otherwise guided to the locality of a leak; the element being caused, by reason of a pressure differential attributable to the leak, to move into and stem or seal the leak. The sealing element may comprise a plurality of individual members of differing buoyancy, each capable of being carried along at a predetermined level in the duct by the flow of fluid therein. The sealing element may carry a tagging device which can be used to assist in locating the leakage site.

Granted: 2008-12-02
Abstract: A medical device for cryotreatment of bodily regions is disclosed. The device comprises an inflatable support structure coupled to the distal end portion of a catheter shaft, the support structure being further enveloped by an expandable membrane to define an expansion chamber between the support structure and the membrane. An inflation lumen is coupled to the support structure to inject an inert, insulating fluid in the support structure, thereby expanding the support structure and the expandable membrane, wherein the resultant expansion chamber formed therebetween is substantially conical in shape. Refrigerant is injected into the expansion chamber, thereby creating localized cooling of tissues adjacent to the expansion chamber, the cooling region being substantially conical in shape. Alternately, a second inflatable support structure is provided inside of the expandable membrane and distal to the first support structure, to define an expansion chamber therebetween that is substantially toroidal in shape, thereby enabling the creation of circumferential cooling regions when refrigerant is injected into said expansion chamber.
