Patent CA-2305286-C (CA)
Inventor: MODI AL
IPC: B65H7/12
Filed: 1998-11-19
Granted: 2005-03-08
Abstract: L'invention concerne un guichet (10) automatique de banque qui identifie et stocke des documents tels que des billets de banque déposés par un utilisateur et distribue de tels documents à l'utilisateur. Les guichets automatiques conventionnels utilisent des détecteurs d'épaisseur permettant de détecter la présence de doubles documents par la détection de la transmittivité de la lumière à travers une zone réduite du billet. Des défauts tels que le marquage, les taches ou la décoloration des notes peut rendre cette détection peu fiable. La présente invention résout ce problème grâce à l'utilisation d'un détecteur (810) d'épaisseur de feuille qui détecte la transmittivité de la lumière sur une largeur relativement importante du billet. Ce détecteur d'épaisseur comprend une source (822) de rayonnement. Le rayonnement émis par cette source est dirigé par un guide (824) de rayonnement vers d'une sortie (826) allongée sensiblement linéaire, transversale à la trajectoire de la feuille. Un récepteur (814) comprend un élément (830) sensible au rayonnement qui présente également un allongement transverse à la trajectoire des feuilles. Les feuilles passant entre l'émetteur et le récepteur induisent des variations dans la quantité de rayonnement atteignant le récepteur.

Title: Generateur de son et machine de jeu video l'utilisant
Inventor: KONDO KOJI
IPC: G10H1/043

Granted: 2006-04-25
Abstract: Lorsque l'on appuie sur n'importe quel interrupteur à bouton-poussoir d'une unité de commande (40), dans un état dans lequel un mode d'entrée de son est sélectionné, le corps (10) d'une machine de jeu vidéo génère des données de fréquences d'une gamme musicale correspondant à l'interrupteur utilisé et il la stocke temporairement. Lorsque l'on incline une manette de jeu (45) de l'unité de commande (40) dans un sens spécifié, le corps (10) de la machine de jeu vidéo modifie les données de fréquences générées selon le degré d'inclinaison de la manette de jeu (45). Ainsi, il est possible d'entrer des sons de diverses gammes musicales à l'aide d'un certain nombre de boutons-poussoirs. On peut ensuite extraire les données de fréquences stockées dans le corps (10) de la machine de jeu vidéo et les convertir en un signal vocal lequel est ensuite retransmis en sortie par un haut-parleur intégré dans un écran cathodique (30). Lorsqu'une musique basée sur le son entré correspond à une musique préétablie, le corps (10) de la machine de jeu vidéo modifie de manière variée le déroulement d'un jeu. Par exemple, un héros est placé dans une position différente de la position courante ou divers articles lui sont attribués.

Abstract: A disclosed gaming machine has a plurality of "gaming peripherals," each communicating with a master gaming controller via a standard peripheral interface such as the USB (Universal Serial Bus). Further, the gaming peripherals employ a standard peripheral controller and one or more specialized "peripheral devices" (e.g., the actual lights, bill validators, ticket printers, etc. that perform the specific functions of the gaming peripherals). Much of the hardware associated with the peripheral controller is identical from one gaming peripheral to the next. Only a portion of the peripheral controller hardware is specific to the different types of gaming peripherals.

Title: Electrical connector system
Inventor: EDWARDS JEFFREY CHARLES
IPC: H01R13/523
Filed: 1999-10-28
Granted: 2006-01-10
Abstract: An electrical connector system is described for use in subsea environments for~ providing electrical connection through the wellhead into a tubular element with apertures for carrying electrical cables downhole. The system includes a circumferential electrically conductor ring which is coupled to, and insulated from, a tubular subsea element such as a tubing hanger, by an elastomeric electrically insulating sealing element, surrounding the conductor ring. The conductor ring is coupled to an electrical annular connector and is adapted to receive an electrical connector of a horizontally mounted electrical connector assembly which is hydraulically actuated to penetrate the elastomeric element in the direction transverse to the longitudinal axis of the tubular element to make electrical contact with the conductor ring. This completes an electrical connection from the electrical connector assembly through the conductor ring to the annular connector which, in turn, is coupled to a cable connected to downhole transducers or electrical equipment. The tubular element and conductor ring fit within a wellhead or tubular casing which has an aligned aperture for receiving the horizontally mounted electrical connector assembly.

Abstract: The invention relates to a process for producing a circumferentially closed hollow profile, which is of frustoconical form in sections, from a sheet-bar blank.      To produce hollow profiles of this type in as simple a manner as possible and with a reliable process, it is proposed that the sheet bar is cut to size in such a manner that a blank with a rectangular section and a ring segment, the summit of which adjoins the centre of one side of the rectangle, while its outer arc, which faces the rectangle, is of approximately the same length as the length of the side of the rectangle, is formed, sheet-bar material also being left on the blank outside the summit, between the ring segment and the side of the rectangle, this material joining the ring segment with the side of the rectangle integrally at all locations and also joining the corners of ring segment and rectangle which are closest together, so as to form a rounded edge contour. Then the side edges of the blank are bent into abutment with one another about the longitudinal centre axis of the blank. After the bending operation, the edges of the sheet-bar blank are joined together by means of a longitudinal seam weld, so as to form a preform of the hollow profile, which is then deformed into the final form by means of internal high-pressure fluid.

Granted: 2009-12-22
Abstract: A process for the preparation of LH-RH derivatives, characterized by subjecting a solution of an LH-RH derivative to both treatment with a synthetic methacrylic resin adsorbent and that with a synthetic aromatic resin adsorbent. According to this process, the formation of by-product impurities including racemates of LH-RH derivatives can be suppressed and such impurities can be effectively removed, which enables the production of LH--RH derivatives having extremely high quality. Further, the process attains satisfactory purification effectively through the two treatment steps and can give LH-RH derivatives efficiently in high yields by easy operations not involving troublesome solid-liquid separation.

Abstract: An arc-fault detecting circuit-breaker system includes a normally closed line circuit breaker in series with a protected electrical circuit element whose current flow is to be interrupted upon the occurrence of an arc fault. A detector senses the rate of change with time of the current flow in the protected electrical circuit element. A silicon-controlled rectifier has a gate of the silicon-controlled rectifier in electrical communication with a detector output signal of the detector. The silicon-controlled rectifier shorts the current flow in the protected electrical circuit element in the event that the detector output signals that the rate of change of current with time in the protected electrical circuit element is in excess of a permitted maximum rate-of-change value, thereby activating the line circuit breaker.
