Inventor: NISHIKAWA TAICHIRO
IPC: H01B7/28
Filed: 1996-01-26
Abstract: Provided is an overhead transmission line comprising a steel core and energization metal stranded wires which are provided on its outer periphery in a plurality of layers.  The outermost layer of the energization metal stranded wires is formed by a stranded wire which is mixedly stranded by an energization aluminum strand and at least one snow melting magnetic metal strand, so that an outer diameter formed by the snow melting magnetic metal strand mixedly stranding the outermost layer is larger than an outer diameter formed by the energization aluminum strand.  According to this ice/snow accretion resistant overhead transmission line, accretive ice/snow can be more effectively melted than the prior art.

Patent CA-2173320-A1 (CA)
Inventor: VAN BUSKIRK RICHARD GLENN
IPC: E21B33/127
Filed: 1993-10-04
Abstract: A wellbore (1) is at least partially obstructed with a partition or obstruction member (5). A fluid slurry of an aggregate mixture of particulate matter is pumped into the wellbore adjacent the partition or obstruction member. The aggregate mixture of particulate material contains at least one component of particulate material, and each of the at least one particulate material components has an average discreteparticle dimension different from that of the other particulate material components. Fluid pressure then is applied to the aggregate material, and fluid is drained from the aggregate material through a fluid drainage passage in the partition or obstruction member. The fluid pressure and drainage of fluid from the aggregate mixture combined to compact the aggregate mixture into a substantially solid, load-bearing, force-transferring, substantially fluid-impermeable plug member (11), which seals a first wellbore region from fluid flow communication with a second wellbore region. Theplug member is easily removed from the wellbore by directing a high-pressure fluid stream toward the plug member, thereby dissolving or disintegrating the particulate material of the plug member into a fluid slurry, which may be circulated out of or suctioned from the wellbore.

Patent CA-2176177-A1 (CA)
Title: Method for consolidation of multiple data sources
Inventor: SZLAM ALEKSANDER
IPC: H04M3/51
Filed: 1996-05-09
Abstract: A method for consolidating the information from multiple information sources so as to provide a uniform set of screens for an agent. All of the information sources are automatically linked in a coherent manner, which is defined by the user. The provision of an information item into a field automatically accesses user-specified information items from the various information sources. The user may combine and present the information from the various information sources in a uniform manner so that a given item of information always appears at the same location on the screen, and in the form desired, regardless of the original display format that is used by the information source. The station (10) receives (501) the initial information item and then sends (503) this information item to the sources specified by the information field, receives additional information items from these sources, and displays or presents the information items received in any desired media type. The station determines (505) whether any of the information item that it received from a source is necessary to access another source. If so then the steps (503 and 505) are repeated with the new information items until all of the information items have been obtained from all of the sources. The station also transfers (507) information items input by the agent to the source specified by the information field into which the agent is entering the information. In this manner, changes to the records of a customer are automatically and instantly made in all of the sources. Thus, the agent need not switch between, be familiar with the details of operation of, or know how to access, a source, screen, or application, because these details are automatically tended to by the station 10. The agent can therefore devote his or her time to speedily and effectively servicing the customer.
Patent CA-2176944-A1 (CA)
Inventor: ERIKSSON TIMO
IPC: B04C5/081
Filed: 1994-12-09
Abstract: A pressurized fluidized bed reactor is provided utilizing a centrifugal separator having a gas space that is distinctly noncircular, preferably having a circularity of greater than or equal to 1.15. Most desirably the cyclone has a quadrate (e.g. square) cross section, and is disposed inside the pressure vessel along With the reactor chamber containing the fluidized bed. A number of ceramiccandle or honeycomb filters may be provided connected to the gas outlet from thecyclone separator, within the pressure vessel, to filter the gas. This construction provides a minimized diameter of the pressure vessel because the reactor chamberwith square cyclones is more compact than if conventional circular cross sectioncyclones are employed. Also a second pressure vessel is not needed for the candle or honeycomb filters since there is sufficient room within the pressure vessel to accommodate them.

Abstract: Un régime thérapeutique destiné à traiter des troubles liés aux stéroïdes gonadiques chez les mammifères consiste à diminuer l'apport en oestrogène, grâce à l'administration d'un antagoniste de la gonadolibérine en une quantité suffisante pour inhiber la prolifération du tissu endométrial sans interrompre d'une manière substantielle la production de l'oestrogène endogène. L'invention concerne également un procédé pour déterminer si la diminution de l'apport en oestrogène par l'administration à un certain rythme d'un antagoniste de la gonadolibérine à un individu est suffisante pour diminuer la concentration en oestradiol à un niveau optimum pour le traitement de troubles liés aux stéroïdes gonadiques, tels que l'endométriose. Ce procédé consiste à effectuer des tests d'hypersensibilité à la progestérone, et à utiliser des schémas posologiques optimaux de l'antagoniste de la gonadolibérine.
Patent CA-2196055-A1 (CA)
Inventor: KAY BRIAN
IPC: C12N11/08
Filed: 1995-04-20
Abstract: The initial action of an enzyme (for instance a catalase) on a substrate (for instance hydrogen peroxide) can be retarded by distributing a solution of the substrate across a primary and a secondary chamber and by immobilizing the enzyme on a surface in the secondary chamber. The subsequent decomposition of the substrate by the enzyme is not retarded. This method can be used in the disinfection of contact lenses by hydrogen peroxide. The surface on which the enzyme is immobilized can be formed from a nylon sheet. High levels of enzyme can be bound to a nylon sheet in which the nylon molecules have been subject to a shear during the formation of the sheet, in order to orientate the molecules within the sheet.
