Patent CA-2178296-A1 (CA)
Inventor: POLANIEC JAMES P
IPC: G01N35/04
Filed: 1996-06-05
Abstract: A magnetic conveyor system for transporting test samples in tubes disposed in a sample rack having a magnetic or magnetically attractive region is described. The magnetic conveyor system includes a drive system, a magnet coupled to the drive system and movable in response to the drive system and a tray having a first surface adapted to receive the sample rack. The magnet is spaced a predetermined distance from the first surface of the tray such that the magnet provides a magnetic force at the surface of the tray. The magnetic force engages the magnetically attractive region of the sample rack disposed on the tray to thereby move the sample rack along the first surface of the tray in response to movement of the drive system. When the tray reaches the end of the rack it is moved onto a processing queue tray where it is available for test purposes. A barcode reader reads a bar code on each test sample as it is placed on the process queue to identify one or more tests to perform . When all samples have received the individual tests the rack exits to an output queue for disposal. When a test must be made on an immediate basis out of normal processing order a sample rack can be inserted into the process queue via a priority rack feed. In the indicated manner, testing can continue without interruption as new racks are added and completed racks removed.

Patent CA-2193135-A1 (CA)
Title: Rack angle and pinion block for wipper blades
Inventor: OLIVEIRA CESAR B
IPC: B60S1/38
Filed: 1996-12-17
Abstract: A pivot block for use in a windshield wiper apparatus is described. The pivot block comprises a first member for attachment to a windshield wiper arm and a second member for attachment to a windshield wiper blade. The first member and the second member are connected by a pivot arm arranged such that the second member pivots relative to the first member. The second member includes shoulders that contact the first member, thereby limiting the range of pivoting motion. In operation, the pivot block promotes tilting of the windshield wiper blade when the windshield wiper arm completes movement in one direction. This in turn orients the windshield wiper blade to clean the windshield as the windshield wiper arm moves in the opposite direction. As a consequence, the windshield wiper blade runs smoothly across the windshield during the windshield wiping process without skipping or jumping regardless of the direction in which the windshield wiper arm is moving.

Title: Preparation of multivesicular liposomes for controlled release of active agents
Inventor: SANKARAM MANTRIPRAGADA B
IPC: B01J13/12
Filed: 1995-09-13
Abstract: Disclosed are multivesicular liposomes (MVL's) containing biologically active substances, the multivesicular liposomes having defined size distribution, adjustable average size, adjustable internal chamber size and number, and a controlled and variable release rate of the biologically active substance. The process involves encapsulating at least one biologically active substance and optionally an osmotic spacer in a first aqueous component encapsulated within the liposomes. The rate of release of the active substance into the surrounding environment in which the liposomes are introduced can be decreased by increasing the osmolarity of the first aqueous component or increased by decreasing the osmolarity.

Abstract: Le système et la technique proposés de représentation d'une image multicolore en demi-teinte sur un dispositif de tirage d'épreuves multicolore à ton continu peuvent être configurés de manière à permettre une technique d'approximation pour déterminer les zones de chevauchement créées par les points lumineux de dispositifs de tirage voisins sur une image imprimée en demi-teinte d'un modèle en demi-teinte. La technique d'approximation permet de tenir compte des effets de toute une série de caratéristiques du dispositif de tirage en demi-teintes - capacité d'adressage, taille du point lumineux dudit dispositif et valeurs chromatiques - sur l'apparence d'une image imprimée en demi-teintes. Ce système et cette technique peuvent être configurés de manière à permettre la prise en compte de l'effet d'enregistrement erroné entre les séparations de couleurs sur l'apparence d'une image imprimée en demi-teinte. Autre variante: le système et la technique peuvent être configurés de manière à utiliser un abstrait géométrique qui centre efficacement le point lumineux circulaire des dispositifs de tirage sur les coins des unités addressables rectangulaires. L'adressage "centré sur coin" permet à l'ordinateur de calculer plus rapidement les chevauchements lorsqu'on utilise une méthode d'approximation ou une technique analytique fondée sur les rapports géométriques, notamment pour déterminer le diamètre du point lumineux des dispositifs de tirage, compris entre un facteur de ?2 et de 2 de la capacité d'adressage du dispositif de tirage en demi-teintes. Enfin, le système et la méthode selon l'invention peuvent incorporer une technique de réduction d'échelle de la capacité d'adressage des valeurs chromatiques représentatives de l'image imprimée en demi-teinte, sans introduction d'artefacts importants.
