Abstract: This invention is an adaptor (80) for coupling rapid exchange-type catheters (10) to a catheter re-sterilizing system. Specifically, the adaptor (80) fluidly couples the guide wire lumen of a rapid exchange-type catheter (10) to a source of sterilant so that the sterilant may be positively directed to and through the guide wire lumen, thereby allowing the catheter to be properly "reprocessed" or sterilized for reuse.

Patent CA-2176117-C (CA)
Title: Generation of high titers of recombinant aav vectors
Inventor: GUGGINO WILLIAM B
IPC: A61K35/76
Filed: 1994-11-03
Granted: 2006-01-03
Abstract: AAV vectors may have utility for gene therapy but heretofore a significant obstacle has been the in- ability to generate sufficient quantities of such recom- binant vectors in amounts that would be clinically useful for human gene therapy application. Stable, helper-free AAV packaging cell lines have been elusive, mainly due to the activities of Rep protein, which down-regulates its own expression and reverses cellular immortaliza- tion. This invention provides packaging systems and processes for packaging AAV vectors that effectively circumvent these problems by replacing the AAV p5 promoter with a heterologous promoter (as depicted in the figure) and that allow for substantially increased packaging efficiency.
Patent CA-2179762-C (CA)
Inventor: DEHN GUNTHER
IPC: B01D46/24
Filed: 1996-06-21
Granted: 2004-06-01
Abstract: A filter for the cleaning of dust laden possibly hot gas includes ceramic filter candles which are closed at one end and positioned in multiple levels one above the other and are connected to laterally spaced apart candle supporting clean gas collectors. The collectors and the filter candles within one level form a filter module which is divided into several mutually separate filter segments in the shape of a circular sector. The collectors of each filter segment are connected to a clean gas collecting channel located on the same level.    A collector free space remains at the center of each module.      A cleaning lance protrudes into each clean gas collecting channel either directly or indirectly for the supply of pressurized, pulsed cleaning gas. This allows the groupwise cleaning of the filter candles and substantially reduces the amount of cleaning gas required for the cleaning of the whole filter unit.

Abstract: A self-sealing framing system is disclosed for curtainwalls, storefronts, and other framing systems for buildings in which frame members are erected in a grid and infill panels set within the openings of the grid. An elastomeric weathering gasket is mounted to a first frame member such that a portion of the weathering gasket overlies a recess formed in a side wall of the frame member. In an undeformed condition the elastomeric weathering gasket normally extends through a plane defined by the side wall of the first frame member. A second frame member oriented substantially perpendicular to the first frame member has an end abutting the side wall of the first frame member. The end of the second frame member contacts the elastomeric weathering gasket and displaces it onto one side of the plane by the contact with the end of the second frame member. A portion of the weathering gasket is displaced into the recess in the side wall of the first frame member. The weathering gasket thus forms a continuous seal between the first and second frame members along the line of contact with the second frame member.

Abstract: The proposed method of determining dew point involves directing the gas under investigation onto a cooled section of an optically transparent body through which a luminous flux is allowed to pass and recording fluctuations in the intensity of the luminous flux, the flow-rate of the gas thus directed onto the cooled section being reduced down to zero while its molecular diffusion is preserved. To limit the flow-rate of the gas impinging on the cooled section (1) and reduce contamination of the optically transparent element, the dew point gauge is provided with a sampling tube (10).
