Patent CA-2180078-A1 (CA)
Title: Discharging fire and explosion suppressants
Inventor: SEARS RICHARD FRANCIS
IPC: A62C35/02
Filed: 1996-06-27
Abstract: A nozzle unit (4) for discharging and atomising a fire or explosion suppressant, comprises a rigid-walled cylindrical container (5) having a nozzle portion (20) at one end with radially directed discharge orifices (22). A barrier having rupturable discs (100,102) normally blocks the nozzle portion (20) from the interior (56) of the container. At the other end of the container, a piston (106) is positioned so as to be sealingly slidable along the container in response to pressure generated by a gas pressure generator (6). The moving piston (106) pressurises the suppressant agent within the hollow interior (56) until the rupturable discs (100, 102) burst. The suppressant agent is accelerated substantially instantaneously and discharged in atomised form through the discharge orifices (22). The gas pressure generator (6) may be a pyrotechnic gas generator. Some of the heated gas is diverted into direct contact with the suppressant immediately before it is discharged via a bore (104), so as to heat and vaporize the discharging suppressant.

Abstract: In a method for treating a combustion exhaust gas from a waste burning facility, the exhaust gas has its temperature lowered to 180 - 230°C, in a temperature lowering unit, is freed of dust in a dry dust collector, passed through a dioxin and NOx removing unit using a vanadium oxide-based catalyst and, thereafter, the exhaust gas at 180 - 230°C is further passed through a heat exchanger to effect heat recovery.  The vanadium oxide-based catalyst is a vanadium oxide alone or the combination thereof either with an oxide of at least one element selected from the group consisting of molybdenum, tin, yttrium, boron and lead or with gold.  In addition, a tungsten oxide may be used.  These catalysts are preferably carried on titania for use.  The method and an apparatus for implementing it require a simple system configuration and yet assure high thermal efficiency while achieving efficient removal of dioxins and nitrogen oxides.

Title: Method and apparatus for currency discrimination
Inventor: GRAVES BRADFORD T
IPC: G06Q20/00
Filed: 1995-03-08
Abstract: An apparatus for currency discriminating comprising first and second stationary scanheads, disposed on opposite sides of a bill transport path, for scanning respective first and second opposing surfaces of a bill traveling along the bill transport path and for producing respective output signals. The bill travels along the transport path in the direction of a predetermined dimension of the bill. A memory stores master characteristic patterns corresponding to associated predetermined surfaces of a plurality of denominations of genuine bills. Sampling circuitry samples the output signals associated with the respective first and second opposing surfaces of the scanned bill. A signal processor is programmed to determine which one of the first and second opposing surfaces corresponds to the associated predetermined surfaces of the plurality of denominations of genuine bills. The processor then correlates the output signal associated with one of the first and second opposing surfaces corresponding to the associated predetermined surfaces with the master characteristic patterns to identify the denomination of the scanned bill.

Title: Optical waveguide method for detecting specific binding events by light scattering
Inventor: STIMPSON DONALD I
IPC: C12Q1/6837
Filed: 1995-09-20
Abstract: A waveguide binding assay method involves detecting the scattering of light directed into the waveguide, the scattering being the result of scattering labels specifically bound to the waveguide within the penetration depth of an evanescent wave. The waveguide may be transparent plastic or glass and the binding is typically by oligonucleotide hybridization or immunological capture. Light scattering labels include colloidal metals or non-metals, including gold, selenium and latex. A  light absorbing member consisting of dye or concentrated particles may also be employed to enhance signal. Real-time binding and dissociation can be monitored visually or by video imaging, such as with a CCD camera and frame grabber software. Hybridization mismatches of as few as one base can be distinguished by real-time melting curves.

Title: Dynamic reconfiguration of network servers
Inventor: NEPUSTIL VLADIMIR
IPC: G06F13/00
Filed: 1997-06-30
Abstract: One or more portions (221) of a database (220) which a primary server (106) uses to process client requests are duplicated (211) on one or more supplemental servers (105). As the clients demand for service increases and the processing load on the primary server becomes excessive (400), the primary server automatically off-loads the processing of those portions of the client requests that require one or more of the duplicated portions onto the supplemental servers by substituting (402) a secondary page (253) or a secondary object in its database that points to the one or more duplicated portions in the supplemental servers for a corresponding primary page (252) or a primary object in its database that points to the one or more duplicated portions in its database. The supplemental servers then serve the portions of the client requests that require the one or more of the duplicated portions. As demand for service decreases and the primary server becomes underloaded (404), it automatically restores (406) the primary page or the primary object in its database and resumes serving the entire client requests.
