Patent EP-0597898-B1 (EP)
Inventor: COUTTS GRAEME FORBES
IPC: E21B47/10

Abstract: A tubing test valve (34, 34a) is described for use with a drill string (20) for pressure testing tubulars and downhole equipment, particularly in a cased hole (12) which has a permanent packer (16) fitted. The valve (34) permits self-filling during running-in, but allows pressure testing when stationary in the well (1). The valve (34) also permits multiple entry of the string to, and retrieval from, permanent packers without committing the tool to the locked open position. This is achieved by providing an apertured ball valve (50, 50a) in the tool housing (42, 42a) which can be moved axially and rotated with the bore (70A, 71A) of the housing (42, 42a). The ball valve has side orifices (54, 54a) and a top orifice (52a) which controls flow through the valve (34, 34a). In one embodiment the ball element (50) is suspended by coil spring (64) above the lower valve seat (56) during running-in and is closed for pressure testing by pressuring with fluid from above. In another embodiment the ball element (50a) is biased by a spring (66a) into engagement with the valve seat (56a) when stationary to allow pressure testing during running as the flow of fluid lifts the ball (50a) off its seat (56a) to allow self-filling. In both embodiments the ball element (50, 50a) contains slots (58, 58a) mounted on pins (62, 62a) which allow the ball to be rotated when the tool is in the packer (16) when engaging the valve seat (56, 56a) to break the seal and allow pressure in the bore above (71A) and below (70A) the ball element (50, 50a) to equalise. This allows the tool to be withdrawn from the packer (16).

Abstract: L'invention se rapporte à un système, dans lequel la longueur du chemin de propagation allant d'un oscillateur laser (6) à un organe condenseur (a6) d'une tête de traitement (5) d'une machine de traitement laser (1), c'est-à-dire la longueur du parcours optique, peut être fixée selon les besoins sur une valeur préétablie. Dans la machine de traitement laser du type à commande multiaxe (1) dans laquelle la tête de traitement (5) est commandée dans ses déplacements dans plusieurs directions axiales (axes des X, des Y et des Z), respectivement, par rapport au corps principal de la machine de traitement par un organe d'entraînement de la tête, on prévoit un mécanisme d'extension/contraction de la longueur du parcours optique, qui sert à étendre ou à contracter la longueur du parcours optique allant de l'oscillateur laser (6) à l'organe condenseur (a6) indépendamment du mouvement de la tête de traitement (5), ce mécanisme étant inséré dans la partie intermédiaire du chemin de propagation. Dans le mécanisme d'extension/contraction de la longueur du parcours optique, on combine entre eux un organe de commande de la longueur du parcours optique et un organe de fixation de la longueur du parcours optique. Le mécanisme d'extension/contraction est pourvu d'un organe de calcul de la valeur du mouvement axial, qui sert à calculer une somme totale de valeurs de mouvement des axes respectifs pour l'entraînement de la tête de traitement (5), et une valeur égale à la moitié de la valeur calculée par l'organe de calcul de la valeur de mouvement axial est introduite dans l'organe de commande de la longueur du parcours optique, afin d'assurer l'entraînement du mécanisme d'extension/contraction de la longueur du parcours optique et afin de compenser les variations de la longueur du parcours optique dues au mouvement de la tête de traitement.

Abstract: A continuous motion cylindrical can decorator is provided with mandrels that receive undecorated cans and a deco chain that carries decorated cans through a curing oven. The mandrels are mounted along the periphery of a continuously rotating carrier. Chain speed is much slower than linear mandrel speed and spacing between pins on the chain is much less than spacing between mandrels. Interposed between the chain and the mandrel carrier is a continuously rotating transfer carrier having a plurality of suction holding devices thereto. As the holding devices move through a transfer region they are in single file and receive cans that are blown from the mandrels. In the transfer region mandrel linear speed is substantially greater than linear speed of the holding devices, and spacing between the latter is much less than spacing between mandrels As the loaded suction holding devices move downstream through a pickup region cans thereon are loaded on two rows of pins carried by the deco chain. Linear speed of the holding devices while moving through the transfer region exceeds chain speed, and in this region the holding devices are spaced apart by a distance that exceeds pin spacing. By the time the holding devices reach the pickup region they are arranged in two rows, are spaced apart and are moving at a speed such that they essentially track the moving pins while the latter are being loaded.

Abstract: An agent for the desulphurization, dephosphorization, desilicization and denitrification of molten iron, ferrochrome and ferromanganese consists of at least one of the following mineral raw materials: alkali-containing plagioclases, alkali-containing orthoclases, montmorillonites (perlite), bentonite, vermiculite, muscovite or zeolite as well as calcium carbide and/or calcium oxide. In combination with calcium carbide, lime, iron ore or scale, mineral constituents lead at the treatment temperatures to effective reduction in undesired accompanying elements such as sulphur, phosphorus, silicon and nitrogen in the molten metals. The resulting slags can very readily be tapped and contain less iron granules than in the case of a treatment with conventional agents. If appropriate, suitable minerals can be concentrated by sintering or in the molten state with alkali metal oxides. The process for treating molten iron, ferrochrome and ferromanganese is characterized by the introduction of the agent by blowing in, stirring in, mixing by shaking of the melt, in a premixed form or by separate addition of the individual components.

Abstract: Procédé de poursuite d'un objet dans la dimension Doppler offrant une meilleure imagerie. Le procédé poursuit le centre du Doppler de l'objet et filtre les estimations brouillées de son historique de phase. La poursuite et le filtrage se combinent pour améliorer le rendement de poursuite et la qualité des images. Des signaux Doppler sont générés par un suiveur Doppler éliminant le mouvement de translation de l'objet. Un traitement par paires d'impulsions produit une estimation du centre Doppler de l'objet. Pour chaque paire d'impulsions adjacentes, un traitemet de paires d'impulsions est appliqué à des cellules de distance individuelles, et les sorties sont combinées afin d'estimer le centre Doppler de l'objet à un temps donné. On utilise un filtre passe-bas après le traitement des paires d'impulsions afin de filtrer des incréments de phase. Le filtrage des incréments de phases filtre ensuite les signaux de sortie provenant du filtre à l'aide d'une courbe de filtrage, telle qu'un polynome de second degré. La récurrence des phases produit alors un historique de phases. L'historique de phases récurrentes est différentiée à l'aide de phases mises à jour retardées de manière appropriée. Les phases de différences sont compensées à l'aide des informations radar provenant du suiveur Doppler brut. Un traitement par transformation rapide de Fourier produit alors une image ayant subi une transformation de Fourier. La sortie du filtre est également traitée afin de mettre à jour la phase et les signaux mis à jour de phases sont renvoyés au suiveur Doppler brut. La mise à jour des phases intègre la sortie du filtre afin de mettre à jour l'historique de phases de l'objet sur la base d'incréments de phases dérivés du filtre. La mise à jour des phases est également retardée afin d'apparier ces phases en synchronisation avec celles de l'étape de récurrence de phases.
