Patent CA-2396435-C (CA)
Inventor: DU PLESSIS FRANCOIS EBERHARDT
IPC: B03D1/14
Filed: 2000-11-23
Granted: 2012-04-03
Abstract: The invention uses machine-vision to improve the performance of a flotation operation to provide a substitute for conventional human vision and problem-solving abilities. The invention redirects the conventional approach of "characterising the froth" to "measuring the froth characteristics". The invention provides a method of monitoring and controlling a mineral mixture flow in a froth flotation cell of a flotation plant which includes the steps of obtaining a series of digital images extracted of froth characteristics from a flotation cell. The digital images are transmitted to a computer for processing thereof into parameter signals of digital parameter froth characteristics. Control signals are produced in response to parameter signals received for causing required variations in froth characteristics in a flotation cell; and the froth characteristics in the flotation cell are controlled in response to the control signals so as to cause required variations in the froth characteristics in the cell.

Abstract: L'invention concerne un télescope à réflexion compact, comprenant un réflecteur primaire sphérique, un réflecteur secondaire et une lentille négative interposée, en alignement axial, entre les deux réflecteurs. La lumière réfléchie par le réflecteur primaire est dirigée à travers la lentille négative et déviée par le réflecteur secondaire vers une lentille positive sur un côté du tube du télescope. La lentille positive dirige les rayons de lumière sur un oculaire, sur une émulsion photographique ou encore sur un détecteur électronique. Le télescope réduit ou élimine pratiquement l'aberration sphérique et peut être configuré de façon à présenter une ouverture numérique utile sensiblement supérieure à celle du réflecteur primaire. Ledit télescope fournit un champ de vision plat et une image à diffraction sensiblement limitée.

Abstract: A tamp pad for a label applicator permits use of a single, reconfigurable pad for use with labels of different sizes. Such a pad is used in a label applicator of the type for separating labels from a continuous carrier strip and carrying the labels to and applying the labels to an object positioned at the applicator. The tamp pad includes a first surface configured to receive a label and secure the label thereto by a vacuum. The first surface has a plurality of vacuum openings arranged in at least two series of openings. Each of the openings in a series is aligned with one another and the openings of each series are spaced from the openings of each other series. A  second surface has a vacuum channel and at least two depending sub-channels formed therein.  The vacuum and sub-channels are configured for receipt of a blocking element to prevent communication of the vacuum through a selected one of the series of openings.

Title: Prothese d'articulation implantable
Inventor: BRYAN VINCENT
IPC: A61B19/00
Filed: 2001-08-07
Granted: 2011-06-07
Abstract: La présente invention concerne un implant chirurgical qui permet de mettre en place une articulation artificielle de type diarthroïde, pouvant être utilisée pour remplacer toute articulation, et pouvant être utilisée en particulier en tant qu'endoprothèse discale. L'invention comprend deux coques rigides opposées ayant chacune une surface extérieure conçue pour s'accoupler avec les surfaces osseuses d'une articulation de sorte que les coques se trouvent immobilisées par frottement entre leur surfaces extérieures et les surfaces osseuses. Ces surfaces extérieures sont suffisamment rugueuses pour permettre à des forces de frottement importantes d'empêcher fortement tout glissement entre les surfaces extérieures et les surfaces osseuses de l'articulation. Elles peuvent être convexes, et, lorsqu'elles sont insérées dans une concavité meulée, elles sont immédiatement mécaniquement stables. Comme souhaité, les surfaces extérieures des coques sont conçues pour permettre l'interposition osseuse, ce qui permet de rendre les coques encore plus stables à leur emplacement. Les surfaces intérieures des coques sont relativement lisses, et sont conçues pour glisser assez facilement contre une partie de la surface extérieure d'un corps central disposé entre les coques. Le corps central a une forme qui coopère avec la forme de la surface intérieure d'une coque de manière à permettre une gamme de mouvements similaires à ceux réalisés avec une articulation saine. Une gaine flexible s'étend entre les bords des coques opposées. La surface intérieure de cette gaine, avec les surfaces intérieures des coques rigides, définit une cavité qui englobe le corps central. Au moins une partie de cette cavité est remplie d'un liquide lubrifiant permettant de réduire encore les forces de frottement entre les surfaces intérieures de la coquille et la surface du corps central.

Abstract: This invention is to automatically extract noteworthy information from a large amount of information. First, a disclosure unit of an individual opinion such as a statement in a personal web page or a bulletin board is extracted from collected contents information, and information (URL and/or statement number) to specify the disclosure unit of the individual opinion is registered.  Next, an object (company name and/or industry type) of the individual opinion is specified. Then, the disclosed contents of the individual opinion are analyzed, so that an evaluation as to the object (good evaluation / bad evaluation) is specified. Besides, the reliability is determined based on referenced degree ranking and based on whether information to indicate the basis of the opinion and/or the identity of the speaker is included. Thus, the evaluation as to the object as characteristics of the individual opinion can be presented to requesters. Besides, for example, only a bad evaluation can be extracted from evaluations as to the object of the individual opinion.  Furthermore, the opinion, which has a high influence degree and is noteworthy, can also be found based on the referenced degree ranking and/or the reliability.
