Patent CA-2269149-A1 (CA)
Title: Operating and mooring facility for tethered gas balloon
Inventor: DAVIDSON JOHN SCOTT
IPC: B64B1/50
Filed: 1999-04-16
Abstract: A mooring facility for a tethered gas balloon comprises a bowl structure capable of receiving the lower portion of an inflated lighter-than-air gas balloon for mooring the balloon. The surface of the bowl structure is complementary to the surface contour of the lower portion of the balloon. A gondola is suspended beneath the balloon and occupies a central recess in the bowl structure when the balloon is moored. The balloon is tethered by a cable and can be raised and lowered between an elevated operating position and a lowered moored position. The facility avoids the need for a large space requirement and can be erected or installed in a built-up area in or adjacent to a town or city.

Title: Method for treating a product and leak-detection installation
Inventor: HURME EERO
IPC: G01M3/22
Filed: 1997-04-15
Abstract: The invention relates to a method and an installation for detecting a leak in a resilient, semi-hard and hard package (1). In the method, a test gas is supplied into the package to subject the content of the package to a first pressure Pp, whereafter the package is maintained for a holding time (T) in a chamber (7) having a gas pressure Pk, and the presence of gas is detected in a measuring space (11) that is in gas flow relationship with the chamber, with a detection apparatus (12, 13). In order for the method to be rapid enough to be suitable for detecting very small holes in packages and for use in production plants without any need to change their operating rate, in accordance with the invention a hydrogen gas having a hydrogen gas content of 0.0001 - 6 % by volume is employed as the test gas supplied into the package (1), the hydrogen gas content of the gas within the chamber (7) being maintained below a reference concentration that is lower than the hydrogen gas content in the package immediately after the addition of hydrogen gas into the package, whereafter the hydrogen gas that has possibly leaked outside the package into the chamber is detected and the package is considered defective if the detected hydrogen gas content is found to be higher by the given limit value than the reference content after the holding time (T). The invention also relates to a method for improving the shelf like of the quality of a product in the form of a foodstuff.

Patent CA-2280024-A1 (CA)
Inventor: EVALDSSON PATRIK
IPC: H01L21/8252
Filed: 1998-02-06
Abstract: A heterobipolar transistor HBT and a laser diode LD are manufactured from a common epitaxial structure comprising a plurality of semiconducting layers (1-9). The transistor can be manufactured directly from the material as it is after finishing the epitaxial steps. For manufacturing the laser diode the structure is changed by diffusing (21) zinc into the material, so that the topmost material layers change their dopant type from n-type to p-type. This is made on selected areas of a wafer, so that transistors and laser diodes thereby can be monolithically integrated. The active region (5) of the laser is located in the collector (3-5) of the transistor, what gives a freedom in designing the components and results in that an individual optimization of the two components can be made. The laser and the HBT can thus be given substantially the same structures, as if they had been individually optimized.  The laser will for example be the type vertical injection and can therefore get the same performance as discrete lasers.

Patent CA-2292277-A1 (CA)
Inventor: CAMPBELL MICHAEL CLARK
IPC: B41J2/515
Filed: 1999-12-16
Abstract: The specification describes a printer containing an angled printer cartridge and a method for printing using the cartridge. The printer is an ink jet printer which includes a print media movement device for moving a print media having through the printer along a print media path and a printer cartridge attached to the printer at an angle between 0°  and 90° relative to an axis perpendicular to an axis along the direction of the media path through the printer. The printer cartridge has a length sufficient to print substantially the entire width of the printed width across the print media and contains a plurality of printheads along at least a portion of the length thereof, each printhead having one or more nozzle arrays. During a printing operation, only a portion of the printheads along the length of the cartridge are activated thus, reducing power consumption during printing.   Angling the printer cartridge also has the advantage of increasing the print quality without increasing the density of nozzles in the nozzle array of the printhead.
Patent CA-2292840-A1 (CA)
Title: Mitofusin genes and their uses
Inventor: HALES KAREN G
IPC: A61K39/00
Filed: 1998-06-05
Abstract: Mitofusin genes and encoded polypeptides are provided, including the Drosophila Fzo protein and its homologs from insects, other invertebrates, yeast, and vertebrates including mouse and humans. Mitofusins are large predicted GTPases with a predicted trans-membrane domain, coiled-coil regions, and a C-terminal region showing a high pl characteristic of mitochondrial matrix proteins. The mitofusins are the first known protein mediator of mitochondrial fusion, and mediate developmentally regulated post-meiotic fusion of mitochondria. Missense mutations that alter conserved residues required for GTP binding in other GTPases inhibit the in vivo fusogenic activity of Fzo but do not affect its localization.

IPC: G02B6/26
Filed: 1998-06-01
Abstract: L'invention concerne une forme améliorée de surface terminale d'une fibre, destinée à améliorer la transmission de puissance optique d'une source à une fibre, ainsi que le procédé de fabrication de cette surface. Selon cette invention, l'extrémité de cette fibre présente une surface terminale clivée, de préférence sensiblement orthogonale par rapport à l'axe de la fibre, ainsi qu'une première et une seconde surfaces angulaires polies, qui croisent ladite surface terminale. Des lignes de rupture, situées entre ces surfaces angulaires et cette surface, s'interrompent à proximité de l'un des bords d'une interface à gainage, et de préférence à l'extérieur de cette interface, lorsque ladite fibre et la lumière transmise sont telles qu'une grande partie de la lumière est transmise dans ladite gaine. On détecte un profil d'intensité spatial de la lumière sortant de l'extrémité de la fibre au cours du processus de fabrication, puis on utilise ce profil pour contrôler le polissage des surface angulaires. Des essais ont démontré qu'une telle extrémité permet d'obtenir le rendement de couplage atteint grâce aux extrémités de fibres cunéiforme à surface plate et angle double, tout en conservant l'essentiel de la facilité de fabrication des extrémités cunéiformes à angle simple.

Patent CA-2299755-A1 (CA)
Title: Natural gas composition transport system and method
Inventor: CAMPBELL STEVE
IPC: F17C1/16
Filed: 2000-02-28
Abstract: A compressed natural gas (CNG) transportation system designed to operate at or just below ambient temperatures, that is either ship-based, truck-mounted, or modular for container transportation. The system is an alternative to LNG, pipeline, or conventional CNG transportation systems, where the foregoing modes of transportation are not practical or feasible. The use of composite pressure vessels provides a critical advantage over conventional CNG concepts that use steel or steel lined pressure vessels. The rupture characteristics of composite pressure vessels exceed those of conventional steel or steel lined pressure vessels. The substantial weight reduction of pressure- equivalent composite pressure vessels overcomes the weight-related problems associated with steel or steel lined pressure vessel concepts. The corrosion resistance of composite pressure vessels allows for the transportation of raw CNG and or compressed natural gas liquids (CNGL) which are most often corrosive. The use of composite vessels with corrosion resistant liners removes the requirement to process the gas and or liquids at or near the source of supply.
