Patent CA-2311473-A1 (CA)
Title: Method and system of communicating in a subterranean well
Inventor: BULMER JAMES H
IPC: E21B47/12
Filed: 2000-06-12
Abstract: Communicating relative to a subterranean well includes encoding information in an amplitude and a duration for a pulse.      A detectable change in response to both the amplitude and duration communicates the information. Two distinct items of information can be encoded wherein the information encoded in the amplitude is distinct from the information encoded in the duration. A single, more highly resolved, item of information can be defined in that the amplitude and the duration can together represent one aspect of the information to be communicated. Particular application is found in a subterranean well having three-phase power conductors connected to a three-phase motor in the well with the amplitude and duration being communicated through the power conductors. A system for communicating in a subterranean well includes an information source, to provide a signal representing a numerical value to be communicated in a subterranean well; it also includes an encoder, connected to the information source, to encode the numerical value into an amplitude and a duration for an analog pulse wherein the amplitude and duration together define the numerical value.

Patent CA-2317596-A1 (CA)
Inventor: DE NORA VITTORIO
IPC: C25C7/02
Filed: 1999-01-19
Abstract: A non-carbon, metal-based high temperature resistant anode of a cell for the production of aluminium has a highly conductive metal-based substrate coated with one or more electrically conductive adherent intermediate protective layers and an outer layer which is electrically conductive and electrochemically active. The electrochemically active layer contains one or more electrocatalysts fostering the oxidation of oxygen ions as well as fostering the formation of biatomic molecular gaseous oxygen from the monoatomicnascent oxygen obtained by the oxidation of the oxygen ions present at the surface of the anode in order to inhibit ionic and/or monoatomic oxygen penetration. The intermediate layer(s) constitute(s) a substantially impermeable barrier to ionic, monoatomic and/or biatomic gaseous oxygen to prevent attack of the metal-based substrate. The electrocatalyst can be iridium, palladium, platinum, rhodium, ruthenium, silicon, tin, zinc, Mischmetal oxides and metals of the Lanthanide series. The applied layer usually comprises electrochemically active constituents selected from oxides, oxyfluorides, phosphides, carbides, in particular spinels such as ferrites.

Abstract: Un dispositif médical implantable selon la présente invention comprend un corps, tel qu'un stent ou un fil, et un isotope présentant une grande section transversale d'activation neutronique, tel que des isotopes ?168¿Yb ou ?124¿Xe, implantés par implantation ionique sur la surface du corps. L'utilisation d'isotopes présentant de grandes sections transversales d'activation neutronique permet d'utiliser un choix plus étendu de substrats, y compris des substrats en acier inoxydable, en nickel, en titane et en alliages de ces métaux, étant donné que le temps nécessaire à l'activation neutronique du dispositif est réduit. Un revêtement de matière à haute densité peut être employé pour servir plusieurs objectifs utiles, tels que le confinement de particules bête indésirables provenant d'espèces radioactives à période longue, la création d'une surface biologiquement inerte et l'augmentation de la radio-opacité pour améliorer la visibilité d'un dispositif médical implanté. Les dispositifs médicaux de cette invention comprennent également des dispositifs médicaux radioactifs contenant des radio-isotopes tels que ?169¿Yb et ?125¿I.

Title: Detection of sequence variation of nucleic acid by shifted termination analysis
Inventor: WANG XIAO BING
IPC: C12Q1/68
Filed: 2000-09-28
Abstract: The invention relates to a method for detecting any mutation at a predetermined site occurring in a known nucleic acid sequence. The method uses primer extension analysis to detect the mutation. Unlabeled terminator is supplied along with labeled non-terminator in the primer extension reaction to detect whether the first nucleic acid base on the template strand that is directly opposite the nucleic acid base immediately 3' to a primer is a mutant. In the primer extension reaction, the terminator is complementary to the wild-type base on the template strand that is directly opposite the nucleic acid base immediately 3' to the primer. Non-terminators are the other nucleotides and are labeled. When the terminator is incorporated into the primer extension strand, primer extension reaction terminates. Incorporation of a labeled non-terminator in the primer extension strand indicates that a mutation has occurred at the predetermined nucleic acid base site.

Patent CA-2335407-A1 (CA)
Title: The rotary vane engine
Inventor: BOUCHER RONALD
IPC: F01C1/46
Filed: 2001-02-12
Abstract: This invention comprises a rotary vane engine that can be used in any application in which a piston driven engine is currently being used. Most currently available engines are complicated and have many moving parts dependent upon one another.   The transference of energy from the combustion chamber to the drive shaft is usually not a direct one and often energy is lost.      The Boucher Rotary Vane Engine has very few moving parts and energy is transferred directly from the combustion chamber to the drive shaft resulting in very little energy loss. This means less fuel is used and more useable energy is available. The simplicity and uniqueness of its design is due mainly to the placement of eccentric rotors and 2 vanes. The engine is made up of 2 halves, a compression half and an expansion half, with similar structure and sharing a single output shaft.

Title: Axle filter for internally vented wheel assembly
Inventor: JONES RONALD LEE II
IPC: F01M13/04
Filed: 1999-09-08
Abstract: A filter (10) is disposed in the interior cavity of each of the axle spindle (Il) sections of a non-drive axle for a heavy duty tractor-trailer, which utilizes internally vented wheel end assemblies. Each filter (10) provides for sufficient air flow from the wheel end assembly cavity into the axle cavity to enable internal venting of any expanding gas from the wheel end assembly cavity into the axle cavity, thereby preventing excessive pressure build-up in the wheel end assembly and possible reduction of the life expectancy of the wheel end assembly main seal. Depending on the filter (10) embodiment employed, the filter prevents or at least lessens the likelihood of migration of contaminates such as oxide scale from the axle cavity into the wheel end assembly cavity, thereby preventing or lessening the likelihood that such contaminates will cause premature wear of the wheel end assembly bearings or main seal.
