Title: Retort of oil shale, oil sands bitumen, coal and hydrocarbon containing soils using steam as heat carrier in fluidized bed reactors
Inventor: RATHBORNE PRESCOTT H
IPC: C10G1/02
Filed: 2000-06-28
Abstract: A fluidized bed retort process is invented for retorting hydrocarbon containing materials such as oil shale, tar sands, coal and hydrocarbon containing soils. having particle diameter of about 7 mm and smaller. A mixture of steam, off-gas and carbon dioxide is used as the heat source and the fluidizing lift gas, and recycled in the process. Hot steam, off-gas and carbon dioxide mixture rapidly increases the temperature of raw particles in the fluidized bed retort, liberates the hydrocarbons with minimal uncontrolled thermal cracking reactions. which increases the recovery efficiency and quality of condensable hydrocarbons. The effluent of the fluidized bed retort, which is composed of steam, off-gas, carbon dioxide, liberated hydrocarbons and solid particles, is dedusted using a cyclone. The cyclone overflow is cooled using a series of heat exchangers, compressed if needed to increase the condensable hydrocarbons yield. The condensed hydrocarbons are separated by using a coalescer followed by an electrostatic precipitator, and, the mixture of steam, off-gas and carbon dioxide is heated using a series of heat exchangers and recycled to the retort as the heat source and fluidizing lift gas. The condensed hydrocarbons are upgraded to synthetic crude oil or marketable products using fractionation. catalytic hydrotreating, catalytic hydrocracking, two step non-catalytic and/or catalytic hydrotreating or coking followed by catalytic hydrogenation processes. A fraction of the steam, off-gas and carbon dioxide mixture is fed to a catalytic fixed bed combustor, at elevated pressures if the cyclone overflow is compressed, to generate heat by combusting its off-gas content using air or pure oxygen as the oxidant. The cyclone underflow, which is the spent ore containing coke and residual hydrocarbons, is fed to a fluidized bed combustor to generate heat by combusting its carbon content using air as the oxidant. The latent heats of the hot combusted spent ore and combustion flue gas generated by the combustion of the spent ore are recovered using a series of heat exchangers and using quench water. Cooled combusted spent ore is transported in the form of a paste, using a pipe-line transportation system, back to the mine site for land reclamation.

Title: Light responsive semiconductor switch with shorted load protection
Inventor: TOMII KAZUSHI
IPC: H03K17/785
Filed: 2000-09-26
Abstract: An improved light responsive semiconductor switch with shorted load protection capable of successfully interrupting a load overcurrent. The switch is includes an output transistor which is triggered by a photovoltaic element to connect a load to a power source thereof, and an overcurrent sensor which provides an overcurrent signal upon seeing an overcurrent condition in the load. A shunt transistor is connected in series with a current limiting resistive element across the photovoltaic element to define a shunt path of flowing the current from the photovoltaic element through the current limiting resistive element away from the output transistor. A latch circuit is included to be energized by the photovoltaic element and to provide an interruption signal once the overcurrent signal is received and hold the interruption signal. The interruption signal turns on the shunt transistor so as to flow the current from the photovoltaic element through the shunt path, thereby turning off the output transistor for interruption of the overcurrent. The current limiting resistive element is connected in series with the shunt transistor to limit the current from the photovoltaic element when the shunt transistor is turned on, thereby providing a supply voltage from the photovoltaic element to the latch circuit. Thus, the latch circuit is enabled to keep providing the interruption signal for reliable interruption of the overcurrent.

Title: Methods, products and apparatus for providing machine unintelligible, human understandable information on a communications network
Inventor: DINKIN SAMUEL
IPC: G06F17/21
Filed: 2001-02-28
Abstract: Methods for processing information to be substantially unintelligible by a machine but understandable by a person include disguising information in the form of text and creating a graphical image file of the text. The text may be disguised before, during or after the creation of the graphical image file. The text may be disguised by manipulating the characters of the text, such as by replacing characters of the text by other characters having a similar appearance or by words corresponding to the characters, or by adding obviously superfluous characters or words to the text, for example. The text may also be disguised by processing the graphical image file to provide a background to the text which has low contrast with respect to the text. An alpha-numeric or textured background may be provided, for example. The graphical image file may be part of a Java Applet. Text may also be disguised through direct encoding in a Java Applet. It would be difficult or impossible for a machine to accurately capture the disguised information with a harvesting program, even if the program used optical character recognition. Information may also be disguised in the form of a dynamic media, such as audio or video. Creation of the audio or video file may be sufficient disguise; the information may be further disguised, as well. The audio or video file may also be part of a Java Applet. Once again, it would be difficult or impossible for a machine to accurately capture such information. The invention is particularly suited for disguising personal information on a communications network, such as an e-mail address on a web page stored on the World Wide Web. Computer readable media storing the media file, software executable to disguise the information, web sites including the disguised information and servers storing the disguised information, are also disclosed.
Patent CA-2339260-A1 (CA)
Inventor: YOSHIDA HIROYUKI
IPC: F02B61/04
Filed: 1999-08-03
Abstract: In an engine intake A/F ratio control system in an outboard engine system, a secondary air passage (P) for supplying secondary air for regulating the A/F ratio of an air-fuel mixture is connected to a carburetor (33) in an intake system of an engine (E), and a duty control valve (68) is connected to the secondary air passage (P). A duty control unit (92) is connected to the duty control valve (68) for controlling the duty ratio of a pulse applied to a coil (76) of the duty control valve (68) , and an LAF sensor (94) is mounted to an exhaust system for detecting an A/F ratio of an exhaust gas to input a detection signal proportional to the A/F ratio of the exhaust gas to the duty control unit (92). Thus, in any of a case when the tolerance of the purifying rate of the catalytic converter is set relatively widely with an engine output taken into consideration to a certain extent, and a case when the set range is shifted to a rich side of the A/R ratio with the engine output taken into serious consideration, the A/F ratio of the exhaust gas can be controlled properly to a desired target value.
