Title: Mud flow back valve
Inventor: HENRIKSEN KNUT H
IPC: E21B43/14
Filed: 2004-09-27
Granted: 2010-06-01
Abstract: A valve for downhole use allows flow of mud or completion fluids but closes when subjected to produced hydrocarbons. The flow through the valve is through an annular passage that features a sleeve preferably made of rubber. The passage remains open during completion operations, but when hydrocarbons are produced the rubber swells and the passage is closed off. Applications include completions involving long horizontal runs and small inside diameter laterals where access to a sliding sleeve with coiled tubing or a wireline run tool is not practical.

Abstract: La présente invention concerne des dispositifs à rayons X portatifs et des procédés pour les utiliser. Ces dispositifs comprennent un tube à rayons X alimenté par un générateur intégré. Le tube à rayons X est protégé par un matériau isolant à faible densité contenant une substance à Z élevé. Ces dispositifs peuvent également comprendre un composant d'affichage intégré. Ces composants permettent de réduire la taille et le poids des dispositifs à rayons X, ce qui améliore leur portabilité. Les dispositifs à rayons X ont également un détecteur de rayons X qui ne leur est pas structurellement fixé et qui de ce fait s'avère autoporteur. En conséquence, les dispositifs à rayons X peuvent être également employés comme caméra numérique à rayons X. Ces dispositifs à rayons X portatifs sont particulièrement utiles pour des applications où la portabilité s'avère importante, par exemple, le travail sur le terrain, la télé-exploitation et d'autres activités mobiles telles que les services de santé ou d'enseignement. Cette portabilité accrue peut être particulièrement utile pour les cabinets dentaires et médicaux multispécialités dans lesquels un seul dispositif à rayons X peut servir dans plusieurs salles au lieu que chacune d'elles soit obligée de détenir son propre dispositif.

Abstract: L'invention concerne un assistant numérique (ou un ordinateur personnel) permettant à une personne chargée du lancement d'une assignation pour infraction de stationnement d'enregistrer l'identificateur (ID) d'étiquette RFID du sabot d'immobilisation d'un véhicule et de transmettre à cette étiquette et à une entité hôte des données d'infraction du type numéro d'assignation, numéro d'immatriculation, heure et date, ID de personne chargée de lancer l'assignation, lieu, données de violations répétées ayant entraîné des amendes non payées ou autres données présaisies dans l'assistant numérique, à l'initiative de ladite personne et via un réseau de communications préféré. On peut ainsi enregistrer électroniquement les données dans l'assistant numérique via un réseau de communications du type Internet ou réseau local, ou bien manuellement au clavier et par téléphone. L'entité hôte comporte une base de données téléchargée avec l'information considérée et fonctionne sur la base d'une corrélation entre les numéros d'étiquette RFID et un numéro de combinaison de déverrouillage pour chaque sabot. Lorsque le sabot est mis en place sur un véhicule détenu et conduit par un récidiviste n'ayant pas payé certaines amendes, les données de l'assistant numérique sont transmises à l'entité hôte dont le numéro de téléphone de contact est mis en évidence sur le véhicule fautif. Le conducteur se met en rapport avec l'entité pour payer l'amende et recevoir en retour la combinaison de déverrouillage. Un dépôt pour le sabot est également acquitté en échange de la combinaison. Lorsque le sabot est retourné, le dépôt est remboursé. Le conducteur peut ainsi libérer et retirer le sabot en quelques minutes à son retour au véhicule et il peut ensuite rapporter le sabot à sa convenance.
