Patent CA-2255816-A1 (CA)
Inventor: SEDERQUIST RICHARD A
IPC: B01J8/02
Filed: 1997-05-16
Abstract: A fuel cell power plant, generally, has a fuel cell stack for electrochemically converting a hydrocarbon fuel into electricity. In order for the hydrocarbon fuel to be used by the fuel cell stack, it must be steam reformed into a hydrogen-rich process gas. This process gas has a carbon monoxide level that would be detrimental to the fuel cell stack, so the process gas is passed through a shift converter to decrease the carbon monoxide level therein prior to feeding the process gas to the fuel cell stack. In order to decrease the level of carbon monoxide without the need to increase the size of the shift converter catalyst bed, or lower the temperature of the process gas as it enters the shift converter to an undesirably low temperature, the shift converter design utilizes an upstream adiabatic zone and a downstream actively cooled zone. The actively cooled zone is cooled by a pressurized water coolant which boils as it cools the process gas stream. The coolant entering the shift converter is essentially a single phase water-stream, and the coolant exiting the shift converter is a two phase water-stream mixture.

Title: Microencapsulated compositions
Inventor: CHEN JIN LING
IPC: A01N25/28
Filed: 1997-05-19
Abstract: Polyurea microcapsules particularly suitable for foliar application are prepared by an interfacial polymerization process in which the polyurea is formed from an aromatic diisocyanate and optionally an aromatic polyisocyanate having 3 or more isocyanate groups, in a weight ratio (when both types of isocyanate are present) of polyisocyanate:diisocyanate of from about 1:100 to about 1:15, and in which the microcapsules are produced having an average particle size of from about 1 to about 5 microns.

Patent CA-2263354-A1 (CA)
Inventor: BARTON WILLIAM M JR
IPC: A63H30/04
Filed: 1997-08-07
Abstract: When closed, switches in pads select toy vehicles and the operation of motors for moving the vehicles in any desired direction and for moving a receptacle for holding transportable elements (e.g. marbles). When sequentially and cyclically interrogated by a central station in one embodiment, each pad sends through wires to the station signals indicating the switch closures in such pad. Such station produces first binary signals addressing the vehicle selected by such pad and second binary signals identifying the motor control operations in such vehicle. The first and second signals for each vehicle are transmitted by the central station by wireless to all of the vehicles at a common carrier frequency modulated by the first and second binary signals. The vehicle identified by the transmitted address demodulates the modulating signals and operates its motors in accordance with such demodulation. When the station fails to receive signals from a pad for a particular period of time, the vehicle selected by such pad becomes available for selection by another pad and such pad can select that vehicle or another vehicle. Stationary accessories (e.g. elevator) connected by wires to the central station become operative when selected by the pads. In another embodiment, individual ones of the pads control the operation of individual ones of the vehicles without the inclusion of a central station.

Title: Method and apparatus for flowing sterile fluid membranes
Inventor: LEA PETER
IPC: A61L2/10
Filed: 1999-06-18
Abstract: A method is provided for sterilizing fluids using bolus dosing of a fluid, stretching of the bolus of fluid into a membrane, such as a thin or ultra-thin film, and subsequent irradiation of the individual fluid membranes which are then recollected after sterilization. A system is provided whereby a fluid moves along a defined pathway in traditional bolus flow where each bolus of fluid is interspersed with a bolus of gas. The bolus of fluid, for example from a patient or other sample, moves along the flow path and the width of the flow path is gradually increased until the fluid bolus is stretched (without breaking) to form a thin fluid membrane which can be completely panned using irradiation (such as ultraviolet irradiation) to sterilize the each bolus which has been stretched into a membrane. After sterilization the width of the flow path is gradually narrowed to a sufficient sized such that the bolus returns to a sufficient size to be collected, typically when it forms a small droplet. The collected portions are recombined thereby rendering the original fluid sample completely sterilized for subsequent reintroduction into a patient or other use.

Title: Method and apparatus for superimposing additional information with image signal
Inventor: OGINO AKIRA
IPC: H04N1/387
Filed: 1999-06-16
Abstract: A method and apparatus for superimposing additional information onto image information in a manner such that the additional information is inconspicuous on the displayed image. The additional information is spread throughout the image signal via logical operation with a pseudo-random code sequence. A dithering process is performed on the spread additional information in which masking patterns are randomly applied to mask some pixels from superimposition, thereby reducing the effective level of the additional information signal. High frequency random noise is added to the dithered additional information to further reduce the perceptible effect of the additional information on the image. The dithered and noise-added additional information signal is superimposed with the image signal, and recorded on a storage medium.
