Title: Systeme de roues retractables pour motoneige
Inventor: MORIN MARIUS
IPC: B62M27/00
Filed: 1999-11-16
Abstract: Un système de roulettes rétractables pouvant s'adapter aux skis de différent s types de motoneige est la solution idéale pour un ou une motoneigiste qui se doit de circuler de temps à autres sur des surfaces abrasives tel que les routes publiques asphaltées et de gravier, voies ferrées, ponts, cours de station services , d'hôtels ou encor e de résidences, planchers de ciment, pavées unies, etc. Cette invention s'inspire d'un systè me de roues, utilisant un cam pivotant, préalablement évoqué dans d'autres demandes de brevet faites par le même inventeur que celle-ci : 2256846 - 2264374. Un cam pivotant, sur  lequel est attaché une roue, est fixé à chacun des skis de la motoneige. Ce cam sert à faire pivoter la roue d'une position à une autre. L'une de ces positions consiste à ce que la  roue se trouve plus basse que la lisse du véhicule tout en étant au centre de gravité du sk i, de sorte à ne pas abîmer le dessous du ski et ses composantes lors d'un déplacement sur un e surface abrasive. Une autre, consiste à positionner le système et la roue de façon à  ce qu'il n'encombre pas la conduite usuelle de la motoneige lorsqu'elle circule dans les sentiers conçus à cet effet ou toutes autres surfaces tel que celles qui sont enneigé es ou encore glacées. Différentes méthodes peuvent être utilisées afin de maintenir le ca m dans la position voulue.

Title: Medical device for in vivo nitric oxide release
Inventor: PAPANDREOU GEORGE
IPC: A61L33/02
Filed: 1998-06-08
Abstract: The preparation and use of medical devices are described. A thiol group agent is loaded onto a medical device such as a stent or a catheter. Preferably, the loading is accomplished onto a polymeric surface (22) that had been activated by water vapor RF plasma treatment. The thiol group agent is structured to exhibit sulfhydryl groups. These sulfhydryl groups are available for interaction with nitric oxide (NO) carriers such as nitrovasodilators. This interaction can take place in situ at an in vivo location within a vascular system, for example, in which the sulfhydryl groups would be delivered by the medical device while the NO carrier will be delivered by suitable pharmaceutical administration means. Alternatively, the NO carrier can be loaded onto the treated medical device surface at a suitable time prior to insertion of the medical device into the body, such as immediately before the initiation of a medical procedure such as stent delivery and implantation.

Patent CA-2297543-A1 (CA)
Inventor: LOCH MICHAEL PAUL WILLY
IPC: B01J37/02
Filed: 2000-02-01
Abstract: The method relates to the production of a coated structure (1) which is suitable for carrying out heterogeneous catalyses. This structure is a catalyst body comprising layers (2, 3) of film-like sheet metal lamina (10) which are arranged one above the other as well as flow channels which are integrated in or between the layers. Some or all of the sheet metal lamina can be reshaped so that the flow channels are formed as a result of a shaping of the sheet metal lamina. Coatings (11) are applied in a container (101) to the individual sheet metal lamina (10) ~ preferably prior to a reshaping ~ with a plasma spray method, namely an LPPS method, using a plasma flame (212) which acts defocusingly on an injected powder jet. These coatings contain catalytically active substances; they are porous or have a high roughness. A value between about 15 and 1500 Pa, preferably between 100 and 500 Pa is set for the pressure in the container. After the coating and where appropriate a reshaping the sheet metal lamina are fitted together into a stack or a winding body. Instead of sheet metal lamina other surface-like structures can also be used.

Title: Receiver calibration technique for global orbiting navigation satellite system (glonass)
Inventor: BALODIS MIROSLAW
IPC: G01S1/00
Filed: 2000-02-07
Abstract: A GLONASS receiver and a corresponding method for its calibration for more precise carrier phase measurements. The receiver includes a conventional receiver channel (36), having a bandpass filter (40) for establishing the sampling bandwidth prior to digitizing a plurality of received satellite signals, each having a different frequency. The receiver also includes a calibration channel (50) in which multiple satellite signals are bandbass filtered (in filter 58) at a single intermediate frequency, to avoid errors resulting from group delay variation introduced by passing multiple satellite signals through a common bandpass filter. The calibration channel (50) downconverts (56) to the intermediate frequency, bandpass filters (58), and then upconverts (60) again. Each satellite signal in turn is processed in this manner by selecting appropriate difference frequencies for downconversion and upconversion. The calibration channel (50) produces a set of reference carrier phase measurements that can be applied to correct errors in carrier phase measurements generated by the conventional receiver channels (36).

Patent CA-2304642-A1 (CA)
Inventor: HARRINGTON JOHN J
IPC: C12N1/19
Filed: 1998-09-25
Abstract: The present invention relates generally to activating gene expression or causing over-expression of a gene by recombination methods in situ. The invention also relates generally to methods for expressing an endogenous gene in a cell at levels higher than those normally found in the cell. In one embodiment of the invention, expression of an endogenous gene is activated or increased following integration into the cell, by non-homologous or illegitimate recombination, of a regulatory sequence that activates expression of the gene. In another embodiment, the expression of the endogenous gene may be further increased by co-integration of one or more amplifiable markers, and selecting for increased copies of the one or more amplifiable markers located on the integrated vector. The invention also provides methods for the identification and expression of genes undiscoverable by current methods since no target sequence is necessary for integration. The invention also provides methods for isolation of nucleic acid molecules (particularly cDNA molecules) encoding transmembrane proteins, and for isolation of cells expressing such transmembrane proteins which may be heterologous transmembrane proteins. The invention also relates to isolated genes, gene products, nucleic acid molecules, and compositions comprising such genes, gene products and nucleic acid molecules, that may be used in a variety of therapeutic and diagnostic applications. Thus, by the present invention, endogenous genes, including those associated with human disease and development, may be activated and isolated without prior knowledge of the sequence, structure, function, or expression profile of the genes.
