Title: Procede pour realiser des coupleurs pour des fibres optiques
Inventor: BERKEY GEORGE E
IPC: G02B6/28
Filed: 1996-11-26
Abstract: On réalise un coupleur pour fibres optiques, formant une gaine, en insérant des portions dénudées d'une pluralité de fibres optiques dans le trou traversant (14) d'un tube en verre, en provoquant l'affaissement de la région médiane (15) de ce tube sur les fibres et en étirant la portion centrale de la région médiane du tube. Le procédé fait appel à un tube en verre (10) dont le trou traversant comprend une portion circulaire et un creux. Plusieurs fibres optiques (21, 22) sont insérées successivement dans le tube par glissement de l'extrémité gainée dans la portion centrale du trou traversant jusqu'à ce que la portion dénudée (23, 24) de la fibre soit centrée dans le tube. La portion dénudée de la fibre est ensuite transférée latéralement dans le creux du trou traversant (14). Après avoir introduit toutes les fibres dans la portion circulaire du trou traversant et les avoir transférées vers le creux, une fibre de remplissage (28) est insérée dans la portion circulaire du trou traversant. Le coupleur résultant présente une perte d'excédent faible.

Inventor: GLOWA MICHAEL P
IPC: A61B17/34
Filed: 1998-05-28
Abstract: An elongated arthroscopic cannula having proximal and distal elastomeric sealing means through which elongated surgical instruments may be inserted.   The cannula seals maintain their effectiveness with and without instruments present within the cannula.   The distal sealing means is a transverse linear slit supported around its perimeter by a racetrack-shaped reinforcing member to engage instruments inserted therethrough and to seal the proximal side of the linear slit from the distal side when no instrument is used.   The proximal sealing means is a floating, circular aperture capable of being laterally moved  and tilted in order to provide a sealing function around an instrument shaft whether or not the shaft is aligned with the axis of the cannula.

Title: Procede et appareil de production de fer metallique
Inventor: MATSUMURA TOSHIHIDE
IPC: C21B13/10
Filed: 1997-03-13
Abstract: L'invention porte sur un procédé de production de fer métallique dans lequel on utilise comme matériaux de départ une briquette contenant de l'oxyde de fer tel que du minerai de fer ou analogue et un réducteur carboné que du charbon ou analogue, l'oxyde étant réduit par la chaleur pour donner l'oxyde métallique. Au cours de la réduction, il se crée une coquille de fer métallique qui grossit à la surface de la briquette tandis que du laitier forme un agrégat à l'intérieur de la coquille. La réduction se poursuit jusqu'à ce qu'il ne reste pratiquement plus d'oxyde de fer dans la coquille de fer métallique. On procède ensuite à un nouveau chauffage pour fondre le fer métallique et le laitier. Le fer métallique et le laitier fondus sont séparés l'un de l'autre de manière à obtenir du fer métallique à taux de métallisation relativement élevé. Le susdit procédé peut être mis en oeuvre efficacement à l'aide de l'appareil de production de fer métallique objet de la présente invention qui permet de produire en continu du fer métallique très pur et cela non seulement à partir d'oxyde de fer à haute teneur en fer, mais également à partir d'oxyde de fer à faible teneur en fer.

Title: 3-d geologic modelling
Inventor: HELWICK STERLING J JR
IPC: G01V1/28
Filed: 1997-03-13
Abstract: Features of subsurface earth reservoirs of interest are made available for analysis by forming three-dimensional, geologic block models (Fig. 4) based on field data. The field data include geological observations, such as lithofacies and porosity values (204) obtained from well data and other sources, as well as geophysical data, usually from seismic surveys. The geologic models representative of subsurface reservoirs so obtained are optimized to match as closely as feasible geologic constraints (116) known or derived from observed geologic data. The models also conform to geophysically based constraints indicated by seismic survey data. The modeled geologic lithofacies and porosity are converted into acoustic velocity and bulk density values, which are then formulated as a seismic response which is then compared with actual seismic data. A perturbation process (246) on lithofacies and porosity can be iteratively repeated until a representation of the reservoir is obtained which is within limits of accuracy or acceptability.

Filed: 1997-04-23
Abstract: L'invention concerne un dispositif de détection du profil de vitesses du béton s'écoulant dans une conduite de symétrie radiale. Ce dispositif comprend d'une part une sonde acoustique, apte à envoyer dans la conduite et le béton, une émission supersonique inclinée par rapport à l'axe principal, et à recevoir en réponse l'émission supersonique perturbée; d'autre part une logique électronique apte à analyser les signaux envoyés par la sonde et à obtenir un diagramme indiquant le profil de vitesses du béton. Selon cette invention, la sonde peut mettre en oeuvre une émission supersonique d'une fréquence comprise entre 20 et 500 KHz. Cette logique électronique traite également les signaux envoyés par la sonde, pour donner une indication de la vitesse, à une fréquence de rafraîchissement allant de 10 à 70 fois par seconde, et prive les signaux de leurs composantes dérivées de la vitesse de propagation afin d'obtenir une mesure de la vitesse selon l'axe acoustique, laquelle mesure n'est pas relative et possède son propre signe.

Title: Ink-jet printing apparatus
Inventor: KOITABASHI NORIBUMI
IPC: B41M5/00
Filed: 1998-12-23
Abstract: Upon performing printing using a dye ink and a pigment ink and in addition a treatment liquid making those inks insoluble, two kinds of inks consisted of the pigment ink and the dye ink are used.  After applying the pigment ink on a printing medium, the dye ink is applied overlaying with the pigment ink.  After mixing these inks on the printing medium, the treatment liquid which makes the inks insoluble, is applied.  In the alternative, a mixed ink in which a pigment ink not requiring a dispersant and the dye, is used.  After application of this mixed ink on the printing medium, the treatment liquid which makes the ink insoluble, is applied. Therefore, problem of "crack", "soaking out", "overflow" or lowering of OD value which can be caused upon reaction of the pigment ink and the dye ink or the mixed ink with the treatment liquid, can be solved to achieve high quality printing.
Patent CA-2259177-A1 (CA)
Inventor: GRIESBACH HENRY LOUIS III
IPC: D01F8/16
Filed: 1997-06-19
Abstract: Side-by-side conjugate filaments made from thermoplastic elastomers and spunbond-type polypropylenes exhibit an extremely high propensity to self-crimp. At appropriate polymer ratios and processing conditions (with mechanical or aerodynamical drawing) the crimp develops spontaneously after relaxation of the attenuation force. The amount of crimp and the degree of elastic properties depend on the elastomer content and the processing conditions. The resulting crimp is typically in the range of 25-200 crimps per inch. This combination of exceptionally high crimp and an elastomer component imparts stretch and recovery properties. The filaments can be wrapped around a cylindrical supporting structure to create a continuous, seamless elastic band, useful for body-fit articles.

Inventor: KITCHING WAYNE WILLIAM
IPC: E21F1/10
Filed: 1999-01-15
Abstract: A safety and energy savings device which will control underground mine ventilation air systems. These Balanced Ventilation Doors will shut down, isolate, and control zones or levels of a mine; either in or out of service.   These Balanced Ventilation Door Systems relate generally to the control of underground mine air ventilation systems. In mine workings; the obvious first concern is the safey of workers underground. Primary in this concern is the control of breathing air. This control of breathing air must be done safely and reliably. The actual operation of existing mine ventilation doors is in itself a safety concern. The reason for this is that ventilation doors in past have worked in direct opposition to the ventilation air flow from the fans. Ventilation air flows can produce as much as 10 or 12 thousand pounds of thrust over the full surface of the doors. Existing ventilation doors are designed to work in direct opposition to this thrust, and therefore require large actuators with extremely high power and force.  These high power actuators in themselves create a multitude of dangerous conditions for workers, just by the very nature of their size and force.
