Patent CA-2493017-C (CA)
Inventor: SELINGER RICHARD
IPC: E21B43/12
Filed: 2003-07-18
Granted: 2011-04-26
Abstract: A method and apparatus for causing pressure variations in a wellbore. A valve mechanism and a sealing device are provided in the wellbore. The valve mechanism is part of a valve device actuatable between open and closed positions. Actuation to the closed position allows an increase in pressure below the sealing device. Actuation to the open position allows fluid to pass through the valve device up the wellbore. The valve device is alternately actuated between closed and open positions to cause cyclical pressure variations below the sealing device. The valve device includes the valve mechanism, a fluid passage, a control mechanism and a delay mechanism for delaying actuation. The increase in pressure in the wellbore below the sealing device is caused by either or both of a fluid entering the wellbore from an adjacent formation or the introduction of a pressurized fluid into the wellbore below the sealing device.

Abstract: A device for application of material to a surface, for example, biocompatible material to a tissue surface in a medical or clinical setting, is adapted to receive one or more biocompatible materials and one or more sources of pressurized medical gas, and to deliver these biocompatible materials via the medical gas(es) to a tissue surface or other surface. A regulation system controls flow of medical gas at a variety of pressures, and flow of biocompatible agent or agents, allowing agents to be sprayed or otherwise deployed onto a tissue surface. Switching apparatus operably connected to the regulation system directs a set of preset treatment positions allowing sequential application of biocompatible materials under various conditions in conjunction with an overall treatment protocol. The device can be used to apply a photoinitiating primer and polymeric sealant to a tissue surface, followed by light activation to form a polymer coating on the surface. The device can easily be operated in a variety of orientations by a user, with switching apparatus arranged for logical, stepwise progression through the protocol in any orientation.

Granted: 2013-11-12
Abstract: Dans des modes de réalisation, l'invention concerne des procédés d'attribution de largeur de bande permettant de détecter une interference avec d'autres systèmes et/ou un redéploiement dans une largeur de bande de remplacement. Des canaux à largeur de bande supérieure peuvent être déployés au niveau de limites de canaux (410) représentant un sous-ensemble des limites des canaux (310) à largeur de bande inférieure et peuvent être empêchés de se recouvrir. Une interférence peut être détectée (930) sur un canal primaire, un canal secondaire ou une combinaison de ces canaux en réponse à des mesures d'énergie (910) des différents canaux. Lorsqu'on détecte une interférence, un ensemble de services de base (BSS)(100) à largeur de bande supérieure peut être transféré dans un canal de remplacement ou peut comprendre une largeur de bande réduite afin d'éviter les interférences. Une interférence peut être mesurée en fonction de l'énergie mesurée sur un canal primaire ou secondaire, et/ou d'une différence entre les deux. On peut utiliser un FFT (1010) pour mesurer l'énergie dans l'un des canaux primaire et secondaire ou dans le deux. Des stations peuvent également surveiller des messages provenant du système de remplacement afin de prendre des décisions d'attribution de canal. L'invention concerne également d'autres aspects variés.

Title: Method and apparatus for flow control of nh3
Inventor: CESSAC KEVIN J
IPC: A01C23/00
Filed: 1998-05-29
Granted: 2012-08-14
Abstract: The present invention provides an apparatus and method for accurately controlling the amount of NH3 to be applied to a field by measuring the NH3 flow rate without condensing or cooling the NH3. The system includes a control station 12 on the vehicle with a tachometer 12A or a GPS system for providing a vehicle speed signal to a control panel 13. The control panel includes a toggle switch 17 for adjusting the opening or closing of a valve 52 in the flow line to regulate the flow through the system, although the control panel alternatively may automatically control the valve 52. The vehicle transports a tank 20 containing liquid NH3 and a tool bar 30 for distributing the NH3 to the soil. After flowing through the flow meter 40, 60, 130, the NH3 is conducted to the soil through a series of hoses, fittings, a distributor, and tubing. The flow meter transmits a signal to the control panel, which is converted to a corrected flow rate signal in response to a fixed value vaporization correction factor. The temperature of the NH3 is also measured to correct for density variations. An improved variable area meter 60,130 uses a hall effect sensor 72 and a magnet 68 mounted on a rotatable vane shaft 70 to overcome problems with prior flow meters. The improved meter 60, 130 is ideally suited for measuring the fluid flow of a low temperature vaporization liquid, such as anhydrous ammonia, propane and butane.

Title: Process for producing a polycrystalline silicon ingot
Inventor: KIMURA YOSHIMICHI
IPC: C01B33/02
Filed: 2005-11-30
Granted: 2011-05-10
Abstract: Provided is a process in which a polycrystalline silicon ingot improved in life time characteristics, which are correlated with the conversion efficiency of solar wafers, is inexpensively produced by the ordinary-pressure hydrogen-atmosphere melting method. In the process, the generation of oxygen and impurities in the silicon melt is inhibited and light-element impurities are removed through reaction or crystallization. Fine crystal grains can be grown at a high rate, and a high-purity polycrystalline silicon ingot having a crystal structure reduced in crystal defect can be grown. A silicon raw material is melted in an atmosphere of 100% hydrogen at ordinary pressure or an elevated pressure to prepare a silicon melt and simultaneously dissolve hydrogen in the silicon melt. The silicon melt containing hydrogen dissolved therein is solidified. Thereafter, the solid is held at a high temperature around the solidification temperature to grow silicon crystal grains in the solid phase and thereby obtain a polycrystalline silicon ingot.
