Granted: 2010-02-23
Abstract: A continuous belt press has upper and lower platens defining a horizontal gap. Upper and lower upstream drums and downstream drums are rotatable on the frame about respective horizontal drum axes at the upstream and downstream ends of the gap. Upper and lower endless steel belts spanned over the respective upper and lower drums each have a working stretch supported by respective upper and lower sets of rollers on the respective platens. Each belt has a pair of edges projecting transversely past the respective rollers and at least one of the drums of each of the belts has a substantially cylindrical central region of a predetermined central diameter bearing through the respective rollers on the working stretch of the respective belt and a pair of edge formations of smaller diameter than the central-region diameter lying outside the central region and in engagement with the edges of the respective belt. The reduced diameter of the drums prevents uneven tensioning of the belts in transverse direction.

Abstract: A latch-type tile mounting system for mounting a tile to the frame of a wall panel. An outwardly extending hook is engaged with the wall panel frame, and includes an outer hook portion. The tile includes a receiver within which the outer hook portion of the hook member is received, and blocking structure that prevents engagement with the outer hook portion. A latch member is movably mounted to the tile over the receiver, and is movable between an open or unlocked position for enabling the outer hook portion to be moved into and out of engagement with the receiver, and a closed or locked position in which the latch member engages the outer hook portion to secure the tile to the frame. The latch member is pivotably movable between its locked and unlocked positions, preferably via a fastener that secures the latch member to the tile. The latch member includes a specially configured opening which receives the outer hook portion of the hook member when the latch member is in its unlocked position, and which defines an engagement edge or surface that is operable to maintain the outer hook portion of the hook member within the receiver when the latch member is in its locked position. The latch member includes an inner stop member and an outer manually engageable tab. The inner stop member engages a surface of the tile to position the latch member in its unlocked position, and the tab engages an outer surface defined by the tile to position the latch member in its locked position.

Abstract: L'invention concerne une caméra de prise de vues électro-optique avec balayage (36) autour de l'axe de roulis, dans laquelle des clichés de scènes, successifs et se chevauchant, sont produits par un ensemble d'imagerie électro-optique. La compensation du déplacement d'image est réalisée électroniquement pour arrêter ou figer le déplacement d'image provoqué par le roulis. L'ensemble d'imagerie réalise cette compensation du déplacement d'image pendant la production des clichés d'imagerie. Ces clichés successifs sont réalisés au moment où la totalité de la caméra (y compris l'ensemble d'imagerie) exécute un mouvement de roulis continu. Le déplacement d'image dû au roulis est arrêté ou figé sans arrêt mécanique du roulis, à la différence des caméras à échelons de la technique antérieure. Les cycles de prises de vue de la caméra avec balayage autour de l'axe de roulis assurent la couverture par balayage du terrain à étudier. Le taux de roulis pour un ensemble électro-optique donné est fonction de la taille du cliché et de la cadence de prise de vues, et peut être régulé par un ordinateur pilote assurant la commande de la caméra. L'invention concerne également un nouveau système optique catoptrique Cassegrain qui assure une compensation du filé.

Abstract: The present invention relates to a method and an apparatus for determining the optical properties of a multi-layered tissue, which is a stratified structure with optical properties that may vary from one layer to the next. More specifically, the invention relates to a method for early detection and characterization of tumours in a multi-layered tissue. "Optical properties" refer to absorption and scattering coefficients, and the asymmetry factor describing the angular dependence of the scattered light. A radiative transfer model pertaining to a coupled air/tissue system is used to provide algorithms for retrieving tissue optical properties and determining the location of tumours embedded in a multi-layered tissue. The tissue is illuminated by collimated light, successively from several directions and with several wavelengths, and light backscattered from the tissue in several directions is measured and used as input to the radiative transfer model to determine tissue optical properties and possible tumour locations.
