Inventor: BRANSON JERREL DALE
IPC: C05F17/00
Filed: 2002-12-17
Granted: 2011-10-25
Abstract: L'invention concerne un procédé et un appareil de traitement des déchets agricoles qui permettent de fabriquer de l'alcool et/ou du biodiésel. Les déchets agricoles sont soumis à une digestion anaérobie qui engendre un flux de biogaz contenant du méthane, lequel est reformé par la suite en gaz de synthèse chargé de monoxyde de carbone et d'hydrogène. Le gaz synthétique est converti en un type d'alcool qui peut être stocké, vendu, utilisé ou introduit directement dans un réacteur pour produire du diesel. Les effluents solides provenant du digesteur anaérobie peuvent servir d'engrais organiques à libération lente autorisés. De plus, les eaux d'égout du processus peuvent être immédiatement réutilisées dans des processus agricoles.

Abstract: L'invention concerne un système de verrouillage de sécurité destiné à un soudage à l'arc. Ce système de verrouillage de sécurité est couplé au soudage à l'arc et tourne autour de celui-ci lorsqu'un utilisateur appuie sur un bouton (15). Il peut y avoir un délai éventuel entre le moment où l'utilisateur appuie sur le bouton et le moment où le soudage à l'arc est mis en fonctionnement. Le système de verrouillage de sécurité maintient le soudage à l'arc en fonctionnement pendant une période prédéterminée où un arc doit être démonté. Le système de verrouillage de sécurité présente un circuit de verrouillage (29) qui réagit à un paramètre qui indique qu'une exécution des soudures est en cours, et qui maintient le soudage à l'arc en fonctionnement jusqu'à ce que le paramètre cesse. Une fois le paramètre a cessé ou si un arc n'est pas démonté dans la période prédéterminée, le système de verrouillage de sécurité arrête le soudage à l'arc.
Patent CA-2475936-C (CA)
Title: Linear motor
Inventor: BOYD JOHN HENRY
IPC: F04B17/04
Filed: 2000-06-21
Granted: 2005-08-02
Abstract: The present invention provides an improved design of linear motor as well as an improved control strategy. The design allows for a shorted stator, where the armature magnets are controlled to reciprocate to a greater maximum displacement than for an equivalent conventional linear motor. The control strategy is such that a minimum of external sensors are required. The linear motor is driven at its resonant frequency ensuring optionally efficient operation. A determination of the maximum current is made based on a relationship with the resonant frequency and the evaporating temperature/pressure of the vapour entering the compressor. The current is then limited to control the maximum displacement to avoid damage.

Abstract: La présente invention concerne une lentille de contact qui a une structure fusionnée et se caractérise par un confort amélioré, des distorsions optiques, telles que les halos, réduites, des discontinuités réduites, une stabilité mécanique améliorée. La lentille présente une partie interne qui s'étend depuis la périphérie de la lentille sur la côté concave de la lentille, et une seconde partie externe centrale fusionnée avec la première partie. Une zone centrale fournit une première puissance optique et une première bande concentrique fournit une seconde puissance optique. Une interface centrale entre la première et la seconde partie a une courbure sensiblement identique à une courbure du côté concave. La seconde partie forme une jonction avec la première partie sur un côté convexe de la lentille sensiblement à l'extérieur du champ de vision de l'oeil d'un utilisateur. Un profil de transition entre la jonction et l'interface centrale détermine, avec le premier et le second indice de réfraction, la seconde puissance optique.
Patent CA-2484769-C (CA)
Inventor: BATEMAN ROBERT HAROLD
IPC: G01N27/62
Filed: 2004-10-14
Granted: 2013-06-04
Abstract: A mass spectrometer is disclosed comprising an ion source 4, a field free or drift region 5 and an ion mirror 7 comprising a reflectron. Metastable parent ions which spontaneously fragment by Post Source Decay whilst passing through the field free or drift region 5 are arranged to enter the ion mirror 7 and be reflected by the reflectron towards an ion detector 8 when the reflectron is maintained at a certain voltage. The process is then repeated with the reflectron being maintained at a slightly lower voltage. Two related sets of time of flight or mass spectral data are obtained for the two different voltage settings of the reflectron. From the two data sets the different times of flight for the same species of fragment ion can be determined. The mass to charge ratio of the parent ion which fragmented to produce the particular species of fragment ion can then be determined from the times of flight of the fragment ions.

Granted: 2008-10-14
Abstract: An information management system is described comprising one or more workstations running applications which allow a user of the workstation to connect to a network, such as the Internet. Each application has an analyser, which monitors transmission data that the application is about to transmit to the network or has just received from the network, and which determines an appropriate action to take regarding that data. The analyser may consult policy data containing a supervisor-defined policy to govern the workstation in order to determine what action to take. Such actions may be extracting data from the transmission data, such as passwords and usernames, digital certificates or eCommerce transaction details for storage and record keeping; ensuring that the transmission data is transmitted at an encryption strength appropriate to the contents of the transmission data; determining whether a check needs to be made as to whether a digital certificate received in transmission is valid; determining whether a transaction about to be made by a user of one of the workstations needs third party approval before it is made; and controlling the transmission of messages, such as e-mails according to a policy.
