Patent CA-2204496-A1 (CA)
Title: Optical multilayer information carrier
Inventor: VOS GERARDUS JOHANNES JOSEPHUS
IPC: G11B7/24041
Filed: 1996-08-29
Abstract: A record carrier is described, which has standard and high-density information layers. The standard density layer (2), e.g. in a standard CD format, is positioned at the bottom of a substrate, and is read out through the substrate with a laser beam. The thickness of the substrate is within the CD specification, e.g. 1.2 mm. At least one high-density layer (3) is formed by a material which is (nearly) transparent for the laser wavelength of standard CD players (.lambda. = 780 nm), but is (at least partially) reflective for shorter wavelengths used for high-density discs (.lambda. = 635 nm). To achieve a high density, a smaller track pitch and smaller pits are used in the high-density layer(s).  To achieve better reading signals from both layers, the high-density layer is positioned closer to the side of entrance of the laser beam in the substrate. This enables a higher numeric aperture of the focusing lens and, therefore, a smaller spot for the shorter wavelength. The high-density layer is preferably positioned midway in the substrate e.g. at 0.6 mm, because in that case the high-density layer configuration will be compatible with two-sided high density discs which have a total thickness of 1.2 mm. The information content of the standard layer may be duplicated on the high-density layer, or it may be represented by a different coding scheme.

Inventor: LAVIGNE PIERRE
IPC: G01B7/14
Filed: 1995-11-08
Abstract: Une méthode est décrite, qui permet d'évaluer de façon quantitative le calage d'un alternateur sans avoir à retirer ou démonter le rotor de l'alternateur, et ce même lorsque l'entrefer de cet alternateur est aussi mince que 10 mm. Cette méthode utilise un capteur plat et mince dont une des faces est pourvue d'un retrait dans lequel un piston est monté. Ce capteur est inséré dans l'entrefer et positionné devant la cale où une évaluation est requise de façon à ce que le piston fasse face à cette cale. Un fluide est alors injecté dans le capteur pour amener le piston à contacter la cale puis presser sur celle-ci tandis que le capteur se trouve adossé au rotor. La pression du fluide ainsi injecté, qui est proportionnelle à la force appliquée sur le ressort se trouvant en arrière de la cale, est mesurée. Le déplacement de la cale lorsque la pression est exercée est également mesuré à l'aide d'une jauge de contrainte extensiométrique fixée à une lame flexible en contact avec le piston. Le calage peut alors être déduit de la force et du déplacement ainsi mesurés. Un appareil pour la mise en oeuvre de cette méthode est également décrit.

Abstract: An electric power generation system has a regulated vacuum ejector for recirculating the fluid fuel stream. The system includes a fuel cell stack (100), a pressurized fuel supply (120) having a pressure control valve (122) for regulating the pressure of the fuel supply, a vacuum ejector (124) interposed between the fuel supply (120) and the stack fuel stream inlet (110), a pressure transducer (132) interposed between the ejector discharge outlet (130) and the stack fuel stream inlet (110), and a pressurized oxidant supply (150) with a pressure transducer (156). The ejector suction inlet (128) is fluidly connected to the fuel stream outlet (112) of the fuel cell stack.  The fuel stream pressure transducer transmits a signal to the pressure control valve to adjust the pressure of the fuel supply when the detected pressure of the fuel stream deviates from a predetermined value. The oxidant stream pressure transducer transmits a signal to the pressure control valve to adjust the pressure of the fuel supply when the detected pressure of the oxidant stream changes. The system is load-following to maintain uniform fuel stream pressure and recirculation ratio over a broad range of operating conditions.  The system also maintains a balance between the pressure of the fuel stream and the pressure of the oxidant stream.

Title: Bulk formation of monolithic polysaccharide-based hydrogels
Inventor: COMBES CRYSTELLE
IPC: C08B37/08
Filed: 1997-10-24
Abstract: The present invention relates to compositions and methods for building monolithic massive hydrogels made of ionic polysaccharides such as Chitin, Chitosan, Alginate, Pectin, Hyaluronic Acid by specific in situ uniform pH changes. Low- to high-molecular weight polybase polysaccharide are dissolved at room temperature in acidic aqueous solutions (2% w/v, pH 4-6). An amide such the urea or ureid is added to the acidic polysaccharide solution and the mixture is homogenized and heated to 80-90°C for initiating the hydrolysis of the amide and the in situ delivery of basic products. The resulting products basify uniformly and continuously the mixture allowing a pH-controlled gelation of the polybase (pH increase from 3-6 to 7-8).  Optical signs of the polybase Chitosan gelation at 37°C appear at pH 6.2-6.5. In a similar way, polyacid polysaccharides such as Alginate or Hyaluronan can be gelled from alkaline solutions by hydrolyzing ester or acid anhydride products such the maleic or acetic anhydride, or the beta-esters and liberating acids in situ.  In both cases, the resulting materials are hydrogen-bond based monolithic massive hydrogels with good physico-mechanical properties, are easily moulded into complex shaped materials and present limited shrinkages.  Polybase or polyacid-based monolithic hydrogels can be obtained with incorporated organic or inorganic components (second polymer or additive). Ionic polysaccharide may be applied to drug and cell delivery systems, implantable devices or encapsulating materials.
