Patent EP-0336477-A1 (EP)
Inventor: STUART JARDINE
IPC: G05B19/4065
Filed: 1989-03-23
Abstract: A method is provided for determining the state of wear of a multicone drill bit. Vibrations generated by the working drill bit are detected and converted into a time oscillatory signal from which a frequency spectrum is derived. The periodicity of the frequency spectrum is extracted. The rate of rotation of at least on cone is determined from said periodicity and the state of wear of the drill bit is derived from said rate of cone rotation. The oscillatory signal represents the variation in amplitude of the vertical or torsional force applied to the drill bit. 
     To extract periodicity, a set of harmonics in the frequency spectrum is given prominence by computing the cepstrum of the frequency spectrum or by obtaining an harmonic-enhanced spectrum. The fundamental frequency in the set of harmonics is determined and the rate of cone rotation is derived from said fundamental frequency.

Dans une première phase, on oxyde partiellement une quantité connue d'échantillon d'huile par exposition à un gaz oxydant tout en diminuant graduellement la température. Dans une seconde phase on procède à une post-oxydation au CO2 et à l'eau, un détecteur contrôlant en continu la quantité de CO2 produite en fonction de la température. On calcule par ordinateur l'indice de cétane de l'huile à partir des données analytiques à l'aide d'un modèle statistique basé sur l'analyse des principaux constituants de la variable aléatoire multiple.

Abstract: L'appareil de chargement automatique de cassettes empilées à bande magnétique comprend une fente de chargement (100) qui reçoit une pile de cassettes à bande magnétique (701). Cette fente est supportée sur le fond par un mécanisme d'indexation qui communique à la pile de cassettes à bande magnétique un mouvement de translation dans une direction descendante de sorte que la cassette à bande magnétique se trouvant tout au bas de la pile se trouve dans une position en regard avec le point d'accès du système d'entraînement à bande magnétique, et elle est supportée par un mécanisme de chargement pour être introduite dans le système d'entraînement de bande magnétique. Une paire de plaques de préhension (101, 102) de la pile, situées de chaque côté de la fente de chargement fonctionnent simultanément pour serrer la pile de cassettes à bande magnétique, à l'exception de la cassette se trouvant tout en bas, lorsque la pile effectue un mouvement de translation vers le bas. Dès que la cassette à bande magnétique se trouvant au bas de la pile est positionnée sur le mécanisme de chargement, le mécanisme de chute est actionné pour être repositionné sous la pile de cassettes à bande magnétique tenue par les plaques de saisie de la pile. Un mécanisme tracteur (126) est ensuite activé pour charger la casette à bande magnétique du mécanisme de chargement dans le système d'entraînement à bande magnétique. Lorsque la casssette à bande magnétique est éjectée de l'appareil à bande magnétique, le mécanisme tracteur la charge sur le mécanisme de chargement où elle est placée sur un mécanisme élévateur (112) qui supporte une pile de cassettes à bande magnétique éjectées.

Abstract: On a mis au point un procédé et un appareil (10, 40) permettant de produire des jets de matière à vitesse élevée. Un générateur (14, 42) d'impulsions de courant électrique est fixé à une extrémité d'une ligne de transmission (16, 44) à deux conducteurs coaxiaux comportant un conducteur cylindrique extérieur (18), un conducteur cylindrique intérieur (20) entre lesquels se trouve un isolant plastique ou céramique solide (21). On assemble de manière conductrice une structure métallique à minces parois coaxiales (22, 30), aux deux conducteurs (18, 20) de la ligne de transmission (16, 44). Une impulsion de courant électrique applique une pression magnétique à la structure métallique (22) et éventuellement la vaporise par explosion, la faisant ainsi infléchir et forçant l'éjection extrudée d'un jet de matière à vitesse élevée. Le jet se compose du métal de la structure (22), ainsi que de la matière comprenant d'éventuelles couches de revêtement (32, 34) disposées sur la structure. On peut avantageusement employer un générateur d'impulsions de courant électrique du type ou du genre (42) à compression de flux magnétique entraîné par explosion, dans la mise en pratique de cette invention.

Le deuxième signal auxiliaire (S2) comprend des informations de fidélité relativement réduite mais a une largeur de bande plus grande. Selon la densité (304) des informations auxiliaires, les premier et deuxième signaux sont sélectionnés (310) de façon à produire un signal auxiliaire de sortie qui est combiné (316) avec les signaux vidéo codés à des fins de transmission.
