Patent CA-2419766-C (CA)
Inventor: LONG DAVID CHESTER

Abstract: L'invention concerne un système et un procédé améliorés pour l'hydrogénation catalytique de monoxyde de carbone, visant à former un mélange d'hydrocarbures par le biais d'une pluralité de réacteurs en série. Un gaz de synthèse pénétrant dans le système sous pression est partiellement converti dans au moins un réacteur de phase initiale, et les effluents sont ensuite injectés dans un réacteur de phase finale. Dans le ou les réacteurs de phase initiale, on extrait continuellement ou périodiquement une partie du catalyseur avec un certain nombre d'hydrocarbures, que l'on soumet à un traitement aux fins de renouvellement, ou de renouvellement et d'amélioration, et que l'on réintroduit ensuite. Le traitement comprend les étapes suivantes: réduction du contexte d'hydrocarbures du mélange extrait, échauffement à une température dépassant au moins celle de l'un des métaux du catalyseur, pour former un produit fondu, élimination de toute scorie formée sur le produit fondu, refroidissement du produit fondu et réduction de la taille des particules du produit solide résultant, sous la forme d'une fine poudre de catalyseur renouvelé. Ce catalyseur peut être traité plus avant (amélioration plus poussée des propriétés) par oxydation en suspension à basse température ou par passivation avant réinjection dans le ou les réacteurs de phase initiale. Le réacteur de phase finale, qui comporte un catalyseur identique ou différent de celui du ou des réacteurs de phase initiale, reçoit de la part de ce ou ces réacteurs une charge à teneur sensiblement réduite en impuretés, ce qui permet d'améliorer l'efficacité et la longévité du catalyseur. Le système peut également faire appel à au moins un réacteur de phase intermédiaire, dans une configuration faisant que toutes les phases sont reliées opérationnelles en série et que tous les réacteurs d'une phase donnée sont reliés en parallèle.

Granted: 2010-03-23
Abstract: A method and apparatus for enabling a local area network wiring structure to simultaneously carry digital data and analog telephone signals on the same transmission medium. It is particularly applicable to a network in star topology, in which remote data units (e.g. personal computers) are each connected to a hub through a cable comprising at least two pairs of conductors, providing a data communication path in each direction. Modules at each end of the cable provide a phantom path for telephony (voice band) signals between a telephone near the data set and a PBX, through both conductor pairs in a phantom circuit arrangement. All such communication paths function simultaneously and without mutual interference. The modules comprise simple and inexpensive passive circuit components.

Abstract: A material and method for treating timber. The material comprises a preservative and a carrier. The carrier is selected such that it remains mobile within the wood and provides for migration of the preservative within the treated wood. By providing a carrier which is mobile within the wood, the timber has a 'self healing' effect wherein the carrier/preservative migrates to any freshly cut or exposed surface of the wood to thereby redistribute and treat such a surface within the preservative and hence maintain integrity of a treatment envelope surrounding the wood.

Title: Data referencing system
Inventor: COLAS NOBLECOURT CHRISTOPHE
IPC: H04N7/16
Filed: 2002-03-21
Granted: 2012-05-29
Abstract: This application describes a method of referencing content in an application.  The method comprises, for a content element, creating a reference to the content element and associating that reference with the content element. This enables the content (for example, text or images) to be dissociated from other features related to content; for example, its presentation on the screen. In this way, control over presentation may be achieved separately from control of the content itself. In an example, a Content Provider 402 provides referenced content to an Operator 404. A Programme Provider 400 sends referenced scenarios to the Operator 404. The Operator 404 resolves the reference and sends data for broadcast by the Broadcaster 406.

Filed: 2003-10-15
Granted: 2008-09-09
Abstract: The invention concerns a method for detecting an underdosage of an analytical test element and optionally for compensating the underdosage. The invention also concerns an analytical system and a test element which are suitable for detecting an underdosage. An underdosage of the test element can be reliably detected and optionally calculated by irradiating the analytical test element in a control wavelength range. For this purpose the test element contains a control substance which interacts with the radiation in the control wavelength range as a function of the contact with the applied amount of sample.

Title: Automatic color correction for sequences of images
Inventor: GONSALVES ROBERT
IPC: H04N9/68
Filed: 2004-03-30
Granted: 2010-12-21
Abstract: Automatic color correction is applied to a scene or clip, including a sequence of images, in a motion picture by selecting a representative image of the scene, analyzing the image and adjusting parameters of a color correction operation that is performed on the sequence of images included in the scene. This operation can be repeated automatically for all scenes or for selected scenes in the motion picture. The parameters may be adjusted to automatically color balance the image while maintaining substantially constant contrast. Analysis of the representative image may include identifying an offset of a peak in a two-dimensional histogram of the colors in the representative image from a white point. Parameters of a color correction operation are adjusted according to this offset. Separate histograms and offsets may be determined for shadows, midtones and highlight regions of the representative image. Analysis of the representative image may include determining a one-dimensional histogram of the luminance information in the representative image. The darkest level and the brightest level in the image are used to balance the image. In particular, the histograms for color channels in the image, such as red, green and blue, are adjusted to match the darkest level and brightest level identified by the luminance histogram.

Inventor: SHEA ARTHUR W
IPC: G05D9/12
Filed: 1996-06-11
Granted: 2007-11-20
Abstract: A fail-safe fluid transfer control apparatus has full redundancy in the response to various inputs such as overfill probe signals, ground detection signals, and the like. Independent microprocessor controllers independently evaluate the inputs and each output control signals to close a respective relay when the inputs indicate that fluid transfer may commence. The relays are arranged in series such that both must be closed for a fluid transfer to commence. The control signals from each controller include a static signal and an alternating signal, both of which must be properly output to close its respective relay. Each controller monitors the state of each relay, and discontinues its control signals if either relay appears to be malfunctioning. Each controller runs an different, independently written firmware program to process the detected inputs to prevent a common firmware error. An optical bypass key replaces conventional mechanical keys and transmits an optically encoded signal to the controller for establishing a bypass condition. A preheating circuit is also provided for providing a dynamic voltage supply to standard thermistor probes which may be encountered.

Granted: 2007-10-02
Abstract: A method for creating a three-dimensional engraving including the steps of providing a three-dimensional solid having a specified shape and size and which is secured within a numerically controlled and processor driven machining center, Additional steps include scanning, into the machining center, data corresponding to a three-dimensional illustration and subsequently projecting, into the solid, the three-dimensional illustration according to individual depths of cut. Yet additional steps include machining, in three-dimensional fashion, a three-dimensional surface within the solid and which corresponds to the individual depths of cut associated with the projected illustration, as well as shading the three-dimensional surface of the solid according to selected depths of machining, this typically occurring following the immersing of the machined solid into an oxide bath and the subsequent abrading removal of a darkened coating formed thereby and which is removed according to depth of cut. The method further includes the step of powder coating the machined solid with a thermoset plastic, followed by baking the solid within an oven to thermoset cure and render transparent the coating.
