Patent CA-2439369-A1 (CA)
Inventor: CHERNOPLEKOV ANATOLY NIKIFOROV
IPC: H04B10/11
Filed: 2002-02-13
Abstract: A wireless optical communication systems using two optical transceivers located at the opposite ends of an optical communication line. The optical communication system can be either two-element, when each of the said transceivers contains one optical transmitter (emitter) and one optical receiver, or it can be four-element, where each of the said transceivers contains two optical transmitters and two optical receivers. The output of each of the optical transmitters is a diverging beam of incoherent electromagnetic radiation arranged to have a cross sectional diameter which is larger than the cross sectional diameter of the respective optical receiver at that point on the communication line at which the respective optical receiver is situated. The invention reduces the probability of communication failure, higher noise resistance, and lowers operation and production costs.

Title: Estimation of localised corrosion penetration
Inventor: EDEN DAVID ANTHONY
IPC: G01N17/02
Filed: 2002-03-08
Abstract: The present invention provides a method and apparatus for estimation of general and localised corrosion penetration rates of metallic materials and objects. The invention can also be used to discriminate between general and localised corrosion. A one, two or three electrode probe having electrodes (101, 102, 103) made of the same material as the material being monitored is located in the same corrosive environment as the material being monitored. An electrochemical harmonic analysis is performed and electrochemical noise signals are monitored, and the resulting responses are analysed and compared to discriminate between general and localised corrosion attack and to determine a localised corrosion penetration rate. A law frequency sine wave is applied to the working electrode. Harmonic analysis of the electrode response provides information regarding the general corrosion rate and the stern-geary constant. Electrochemical noise analysis of the electrode response and comparison with harmonic data provides a means of determination of localised corrosion penetration rate.

Abstract: L'invention concerne un joint à bille amélioré destiné à être utilisé avec des articulateurs de modèles dentaires vertex. Ce joint comprend deux supports articulés à une extrémité et respectivement reliés, à l'autre extrémité par un joint à bille, à une plaque de pierre dentaire distincte portant la pièce dentaire coulée respective. Les joints à bille ont des moyens mécaniques amovibles permettant d'attacher la bille au siège à bille une fois que les plaques ont été alignées pour mordre et assurer un ajustement occlusal entre les pièces moulées dentaires. L'attachement de la bille au siège s'effectue par ajustement mécanique du diamètre du siège et de la bille pour créer une force de friction qui retient la bille dans le siège. Dans un mode de réalisation, le moyen mécanique comprend une pince C dotée d'une bande concave ayant un diamètre transversal sensiblement égal au diamètre de la bille et un interstice permettant à la bille d'être encliquetée dans la pince C. On utilise un boulon qui traverse les flasques aux extrémités de la pince C pour réduire l'interstice séparant les flasques, ce qui permet d'augmenter de façon illimitée la force de serrage frictionnelle sur la bille. Dans un autre mode de réalisation, la bille est insérée dans une cavité sphérique tronquée formée sur une tige réalisée en quatre parties avec des interstices entre ces parties. Les interstices de bille permettent à la bille d'être encliquetée dans la cavité sphérique servant de siège du joint. On insère un boulon fileté à travers la base de support et la tige portant la bille pour l'amener entre les quatre parties dans le siège, ce qui permet de séparer les quatre parties de la bille dans la cavité pour produire la force de friction nécessaire entre la bille et la paroi de cavité afin d'attacher la bille dans le siège.

Patent CA-2456107-A1 (CA)
Title: Fracture closure pressure determination
Inventor: WENG XIAOWEI
IPC: E21B/
Filed: 2002-07-19
Abstract: A method for assessing the fracture pressure closure is proposed. This method includes first injecting a fluid into the formation at a first generally constant rate Q to create a fracture, and then, dropping the pumping rate to significantly smaller feed rate q so that the volume of the fracture becomes constant, in other words. As the fracture volume becomes constant at equilibrium, the well is shut-in. The wellbore pressure is monitored and the closure pressure is determined from the analysis of the wellbore pressure using a time-function of the dimensionless "shut-in" time, defined as the ratio of time since shutting to pumping time. This method provides a way of estimating the friction component of the monitored wellbore pressure due to the fracture tortuosity and friction. It is applicable to the art of fracturing subterranean formations and more particularly to the process of designing and analyzing stimulation treatments.
