Title: Mecanisme de transmission de puissance, impacteur a entrainement hydraulique et ses utilisations
Inventor: ZENG YIJIN
IPC: E21B1/24
Filed: 2003-01-14
Abstract: La présente invention concerne le module de transmission d'énergie d'un impacteur et un impacteur à jet hydraulique. La corrosion qui s'attaquait au joint étanche en caoutchouc de l'impacteur à jet hydraulique, et à la fente d'écoulement du couvercle supérieur raccourcissait la durée de vie de service de l'impacteur. Le grand nombre de pièces diminuait l'efficacité du module de transmission. Pour y remédier, l'invention cherche à augmenter la vitesse de forage du puits et/ou la durée de vie de service de l'impacteur de forme allongée. A cet effet, on réalise dans une paroi latérale un passage en établissant une séparation entre d'une part de la paroi intérieure garnissant le manchon extérieur et d'autre part le joint étanche. On peut ainsi s'affranchir du joint étanche, ce qui fait le module de transmission d'énergie se combine à son articulation inférieure, réduisant ainsi d'autant la perte de puissance à l'impact pendant la transmission. En outre, on place dans la fente d'écoulement de la buse un matériau plus lubrifiant que celui de la fente d'écoulement. En l'espèce, la buse est prise parmi un jeu de buses de différents diamètres de façon à pouvoir remplacer la buse en fonction des différents écoulements, ce qui a pour résultat de soulager de façon efficace l'abrasion de la fente d'écoulement.

Patent CA-2471157-A1 (CA)
Inventor: STASZEWSKI WIESLAW JERZY
IPC: G01N29/04
Filed: 2002-12-18
Abstract: The present invention relates to testing structures or bodies to determine if they contain defects. The defects may be, for example, cracks, delamination etc. Conventional non-destructive testing exploits the non-linearities of such defects. The non-linearities produce intermodulation products in the form of side-bands of an excitation signal. The amplitudes of the side-bands are used to provide an indication of the structural health of the body. However, it has been found that such methods of testing bodies suffer from the vagaries of the environment, temperature and transducer manufacturing tolerances etc. This can lead to inaccurate test results. Suitably, embodiments of the present invention provide a method of determining the structural health of a body; the method comprising the steps of identifying at least one phase characteristic of a signal represented by first data, the first data being, or having been, derived from the body while bearing at least a guided wave, produced in response to application of a first excitation signal to the body, and a second excitation signal; and providing a measure of the structural health of the body using the at least one phase characteristic. More accurate testing can be performed that is independent of at least some of the above-mentioned vagaries by basing the assessment of the structural body on defect induced phase modulation.

Title: Pressure protection valve
Inventor: HUCKABY EDDIE D
IPC: F16K15/02
Filed: 2004-11-18
Abstract: A valve is provided having a housing with an inlet and an outlet. Within the confines of the housing is a fluid flow path that allows for fluid communication between the inlet and the outlet. The valve includes a valve element that is movable to and from a position where it blocks fluid communication along the fluid flow path, thereby closing the valve. The valve also includes a resilient member provided in a chamber of the valve that is fluidly sealed from the fluid flow path. The resilient member urges the valve element to move to the position for closing the valve. When the pressure of fluid entering the inlet exceeds a preselected amount, the pressure of the fluid overcomes the urging of the resilient member and the valve element moves towards a position that allows fluid communication along the fluid flow path, thereby opening the valve.

Abstract: Methods and apparatus for use in reestablishing a data connection with a wireless communication network are described. Initially, a wireless communication device maintains a data connection with a wireless communicati on network. During an out-of-coverage condition with the network, the wireless device is powered off. This causes the wireless device to reset its paramete rs associated with the data connection, but the wireless network will fail to disconnect since the wireless device is out-of-coverage. After being powered back (504) on and regaining network coverage (506), the wireless device transmits a message to the network which causes one or more network paramete rs associated with the data connection to be reset (508). Subsequently, the wireless device transmits one or more additional messages to the network for reestab~lishing the data connection (510). In the preferred embodiment, the data connection is a Packet Data Protocol (PDP) context with a General Packe t Radio Service (GPRS) attachment, the message is a disconnect frame, and the one or more additional messages include a General Packet Radio Service (GPRS ) attach request. Advantageously, a data connection is substantially seamlessl y maintained for the wireless device despite network connection complexities.< /SDOAB>
