Abstract: On présente aux cliniciens une nouvelle utilisation de ligands spécifiques d'antigènes de classe I du complexe majeur d'histocompatiblité (CMA) et, en particulier, d'antigènes HLA-ABC, utilisation consistant à détecter et diagnostiquer l'endométriose. On présente aussi un procédé et une trousse d'essai permettant le diagnostic de l'endométriose, de préférence par immunohistochimie, à l'aide d'un anticorps monoclonal anti-HLA-ABC en guise de ligand ou de réactif de diagnostic préféré. Ce nouveau procédé est non invasif et permet un dépistage plus fiable que la coelioscopie utilisée conventionnellement. Quand l'endomètre d'une femme donne des résultats négatifs avec le procédé décrit, ceci évite le recours à la coelioscopie qui constitue un procédé invasif de détection de l'endométriose. Ce procédé peut s'utiliser avec un spécimen obtenu à partir de l'endomètre d'une patiente mais n'exige pas de spécimen échantillonné directement à partir des foyers d'endométriose.

Title: Apparatus for monitoring opening of sealed containers
Inventor: GAGNON ANDRE
IPC: G08B13/14
Filed: 1997-06-09
Abstract: Apparatus for monitoring opening of sealed enclosures, especially, but not exclusively, sealed containers containing goods-in-transit, such as goods vehicles, maritime containers or transport containers of the kind carried by tractor-trailers, ships, trains or aeroplanes comprises a radio receiver unit having at least one antenna for reception of radio signals. The receiver unit is housed within the enclosure and operates to scan a predetermined band of radio frequencies, periodically or continuously, and detect a sudden change in signal level. When it detects such a change in radio signal level, the receiver generates an alarm signal. Alternatively, the receiver may detect the difference between internal and external radio signal levels and determine the container to have been opened if the difference is less than a preset threshold.

Inventor: ERLAND JONATHAN
IPC: G03B15/00
Filed: 1997-09-15
Abstract: A floating segmented conglomerate backing screen for use in underwater composite photography. A plurality of buoyant pads of an essentially hexagonal shape have surfaces exhibiting specific chrominance and luminance properties as required for a traveling mate process. The individual segments are deployed onto a liquid surface of a finite area in a quantity sufficient to substantially cover the liquid surface in its entirety, in an edge-to-edge, floating, conglomerate relationship. The floating raft created by the segments permits egress and ingress for people and equipment directly through the raft and likewise permits the escape of air rising from below the surface. When appropriately illuminated from either below or above the surface, or both, the chrominance and luminance of the raft is such that an essentially monochromatic backing field is provided for traveling matte processes. The individual segments are constructed of an inert plastic such as polypropylene, polystyrene, polyurethane or similar plastic which has inclusions of inert gas and is compounded with dyes and pigments, which may include fluorescence, to achieve either black or white or any of a variety of specific spectral loci and luminances, for the purpose of providing a precise chromatic actinic stimulus response for a silver halide photographic film, or similar response for electronic imaging devices. Foreground subject matter interposed between the camera and the segmented conglomerate backing will therefore be readily distinguished and "matted" for compositing by methods well known to the art.

Patent CA-2219203-A1 (CA)
Inventor: KNELLER GLENN R
IPC: F41B5/10
Filed: 1997-10-23
Abstract: The invention provides an accessory for a compound bow having a center section including an arrow support, upper and lower resilient power limbs extending upwardly and downwardly respectively from the center section, a tension compensating cam mechanism at the free end of each of the limbs, first and second tension cables extending between said cam mechanisms, and a drawstring extending between said cam mechanisms. The accessory involves a spreader that fits within an existing tension cable, dividing or separating it into a pair of cable strand portions that are generally parallel and are located symmetrically on each side of the vertical centerline of the bow. The use of the accessory means that the guide rod and slider of a conventional compound bow are no longer required as all forces imposed on and created by the bow during the launch of an arrow are symmetrical with respect to the vertical centerline. The accuracy of the archer is improved since he does no have to compensate for offset forces imposed by conventional tension cable arrangements.

Abstract: La présente invention se rapporte à un procédé et à un appareil pour purifier de l'acide téréphtalique brut à partir d'une dispersion de liquide de celui-ci contenant également des impuretés choisies parmi des produits de départ n'ayant pas réagis, des solvants, des produits de réactions secondaires et/ou d'autres matériaux indésirables. Le procédé comprend les étapes de filtrage de la dispersion afin de former un gâteau de filtrage d'acide téréphtalique brut (F-1), de dissolution du gâteau de filtrage dans un solvant de cristallisation sélective à une température élevée afin d'obtenir une solution (T-3, T-4), de cristallisation de l'acide téréphtalique purifié provenant de la solution dans le solvant de cristallisation en diminuant la température de la solution (S-1), et de séparation de l'acide téréphtalique purifié cristallisé de la solution (F-2). Selon l'invention, le solvant de cristallisation sélective est non aqueux, non corrosif et essentiellement non réactif avec l'acide téréphtalique. De préférence, le solvant de cristallisation sélective est une N-méthyle pyrrolidone. Le procédé et l'appareil produisent un acide téréphtalique purifié présentant une pureté souhaitable pour être utilisé dans la formation de résine de polyester et d'autres produits à un coût attractif économiquement et à des conditions de fonctionnement de sévérité réduite exigeant un investissement de capital moindre et un traitement simplifié.

Title: Procede de detachement de films
Inventor: BARON DAVID T
IPC: H05K3/26
Filed: 1996-08-21
Abstract: L'invention concerne un procédé et un dispositif de détachement uniforme, par voie chimique, sous la forme de fines particules facilement filtrables, de couches de résist recouvrant des plaques galvanisées. Ce procédé est particulièrement adapté aux installations horizontales de production en continu de cartes imprimées. Selon la technique antérieure, on utilise des procédés d'aspersion et de projection pour détacher le résist. Mais ces procédés présentent notamment l'inconvénient de la courte durée de vie du bain dans la mesure où l'on ne peut pas extraire complètement par filtrage le résist de la solution en raison de sa dilution. Selon l'invention, on détache le résist de la surface de la carte imprimée à l'aide d'un flux modéré de liquides de traitement. Lors d'une première étape du procédé, on projette une importante quantité de liquide de traitement sur la surface des cartes imprimées au moyen d'ajutages allongés pour provoquer un gonflement. Pour détacher le film lors d'une deuxième étape, on utilise de préférence des ajutages présentant une zone de pression et une zone d'aspiration. Le traitement ultérieur est réalisé par arrosage à l'aide de flux intenses. Grâce à un rinçage multiple en cascade, le procédé évite toute production d'eau et la durée de vie du décapant est allongée. Le résist détaché des surfaces est acheminé par le plus court chemin vers un filtre à matières solides et est séparé du solvant avant sa dilution. Le film est extrait par filtrage dans sa quasi totalité et à l'état pratiquement sec.
