Patent CA-2198333-A1 (CA)
Title: Method of and apparatus for reforming fuel and fuel cell system with fuel-reforming apparatus incorporated therein
Inventor: NEGISHI YOSHIMASA
IPC: B01B1/00
Filed: 1997-02-24
Abstract: Methanol supplied as a raw fuel is mixed with water, vaporized in an evaporator 24, and supplied to a reformer 22 as a raw fuel gas.          The reformer 22 also receives a supply of the compressed air from an air tank 36.  The raw fuel gas is mixed with the compressed air in the reformer 22.  An oxidation reaction of methanol supplied as the raw fuel proceeds in the reformer 22 to generate hydrogen and carbon dioxide,  while a steam reforming reaction of methanol simultaneously proceeds in the reformer 22 to generate hydrogen and carbon dioxide.  The amount of heat required for the endothermic reforming reaction can be supplied by the oxidation reaction of methanol.  No external heat source is accordingly required in the reformer 22 to supply the heat required for the reforming reaction.

Title: Advanced intelligent network trigger item and method
Inventor: GAWARGY MICHAEL MUMTAZ
IPC: H04Q3/00
Filed: 1997-10-23
Abstract: An advanced intelligent network trigger item and method provides a way to prevent a query being sent to a service control point on the receipt of predetermined digits. The trigger item instance, called and escape item, includes an action, escape, that is predefined to stop further activity based on the received digits. The benefits of having negative logic available in the form of an escape item may simplify certain service scenarios. For instance it will take many fewer definitions to turn on or off a small subset of a digit range using escape items than just with trigger items.

Title: Optical data storage medium and methods for its writing and reading
Inventor: NORDAL PER-ERIK
IPC: G11B7/24
Filed: 1996-06-24
Abstract: In an optical data storage medium with a storage area formed from a tranparent, homogeneous base material and with a number of optically active structures at one side of the storage area, the optically active structures are diffractive optical elements which can focus a beam of light incident on the storage area on to one or more points in the storage area and/or a redirected beam of light or emitted light radiation from this or these points on to a point outside the optical storage medium. During writing/reading of data in the storage medium, the diffractive optical elements are used for focusing the write/read beam in order to generate a data carrying structure or read data stored in such a data carrying structure, respectively. By exploiting the special optical properties of diffractive optical elements, it is possible to achieve parallel writing/reading of data, possibly in several parallel storage layers in the optical storage medium or randomly distributed therein, the optical storage medium thus providing a genuine volumetric storage and a corresponding genuine volumetric accessing of the stored data.

Patent CA-2226472-A1 (CA)
Inventor: LOCKWOOD FRANCES E
IPC: C09K5/20
Filed: 1998-01-08
Abstract: The present invention provides corrosion inhibition formulations and compositions for inhibiting mineral scale and the corrosion of metals particularly the cavitation corrosion of aluminum in the presence of aqueous liquids. The combination of a mixture of polymeric polycarboxylates, azoles, nitrate salts, phosphates, stabilized silicates and transition metal compounds provide a synergistic protective effect against the cavitation corrosion of aluminum in aqueous liquids reducing the corrosion rate and is effective at relatively low concentrations and varying pH ranges. The addition of selected polymeric polycarboxylates not only significantly reduces glycol based coolant cavitation erosion-corrosion, heat rejecting aluminum corrosion, and hard water precipitates and scale, it has been discovered that polymeric polycarboxylates in combination with siloxane stabilized silicates enhance secondary silicate stabilization leading to improvement in aluminum corrosion protection and coolant life when utilized with selected amounts of the above-identified additives. The formulations are particularly suitable for automotive applications.
Patent CA-2228240-A1 (CA)
Inventor: CHEN BRIAN
IPC: H04J9/00
Filed: 1998-01-30
Abstract: Dans un système de radiodiffusion simultanée de signaux FM analogiques et à modulation numérique dans la même bande de fréquences, l'effet du signal FM analogique sur le signal à modulation numérique lors de la radiodiffusion simultanée est calculé et supprimé de ce dernier signal avant sa transmission. Par conséquent, la transmission numérique est libre de tout brouillage dû au signal FM analogique. En outre, la transmission numérique est réalisée par insertion adaptative, dans la bande FM, d'un nombre variable dans le temps de porteuses modulées par des données numériques. Les porteuses sont sélectionnées trame par trame de façon à contrôler leur interférence avec le signal FM analogique. Conformément à l'invention, les porteuses sont sélectionnées selon un ordre prédéterminé. Dans une version préférée, elles sont regroupées de façon contiguë dans la bande FM. Par conséquent, le taux de données de commande à transmettre à un récepteur pour l'identification des porteuses insérées est avantageusement faible.
