Patent CA-2238531-C (CA)
Title: Method of and apparatus for producing power in solvent deasphalting units
Inventor: HOOD RICHARD L
IPC: C10G21/00
Filed: 1996-12-12
Granted: 2003-11-11
Abstract: Power is generated in an organic Rankine cycle turbine (115) by expanding a stream of solvent vapor (112) produced by a flash drum in a deasphalting unit to produce a stream of expanded solvent vapor (118) that is combined with a stream of solvent vapor and steam from a stripper (122) of the deasphalting unit. Heat is extracted from the combined stream by an organic fluid that is vaporized and supplied to a Rankine cycle organic vapor turbine (155) that produces power and expanded organic vapor. The solvent is recovered from the cooled, combined stream and re-used in the deasphalting unit. Heat extracted from products of the deasphalting unit vaporizes an organic fluid that is expanded in an organic vapor turbine (175) that generates power.

Title: Energy efficient liquefaction of biomaterials by thermolysis
Inventor: RADLEIN DESMOND
IPC: C10B47/24
Filed: 1997-04-04
Granted: 2009-07-07
Abstract: A thermolysis process for the production of volatiles for an external combustor (203) or liquefaction of biomass solids in which specific and previously unrecognized conditions are employed. The thermolysis is carried out in a single deep fluidized bed (211) of inert material operating at near atmospheric pressure, relatively low temperature, long solids and gas residence times and moderate heating rates.  The distribution of the thermolysis products among solid (char) and gases under these conditions is unique. The product effluent can be either quenched to produce a high liquid yield in addition to a low char yield or the volatile effluent can be used in either the same combustor (203) or a second combustor (310) to produce heat energy a particularly high efficiency system. In using a quencher (403), the quenched liquid is of similar composition to those obtained by so called fast pyrolysis procees of the prior art. The specified conditions are such as to allow production of liquids in high yields in an energy efficient nianner.  The low severity of the conditions in comparison with previous approaches allows simplified process design and scale-up leading to lower capital and operating costs as well as easier control.

Title: Method and apparatus for decoding bar code symbols using ratio analysis of module size
Inventor: LEI MING
IPC: G06K7/14
Filed: 1997-10-01
Granted: 2002-09-10
Abstract: An improved method and apparatus for decoding bar code sym-bols using an analysis of the ratios of the module size for the bars and spaces of the bar code. The invention is applicable to any bar code having one or more nominal widths in the bars and spaces, and is par-ticularly useful in bar codes having multiples widths in the specification for the bar code and in situations where the bar code signal has a low signal-to-noise ratio, or is degraded because of a damaged, smudged, or dirty bar code, or where the bar code is read at less than the opti-mum angle. The invention identifies misdecoded characters and uses adaptive techniques to decode characters previously non-decodable or misdecoded by standard methods, thereby improving the decode rate as compared to prior techniques. The decoding rate is improved with-out having to re-scan the bar code for a new signal, thereby making the invention particularly useful for high-speed or one-pass decoding operations.

Granted: 2003-09-16
Abstract: An audio signal coded by successive frames is represented by a binary stream (F) received with data (BFI) signalling possible erased frames. For each frame, the method consists in filtering the excitation signal (E<k>(n)), formed on the basis of excitation parameters (EX(n)) recovered in the binary stream (valid frame) or estimated otherwise (erased frame), using a synthesis filter (22) to obtain a decoded signal ( SIGMA n(t)). A linear prediction of the decoded signal is carried out up to the preceding frame to estimate a synthesis filter relative to the current frame. The synthesis filters used as long as no frame is erased are in conformity with the estimated synthesis filters. If one frame n0 is erased, the synthesis filter used for a subsequent frame n0+i is determined by a weighted combination of the estimated filter relative to the frame n0+i with at least one synthesis filter used since the frame n0.

Title: User interface for transferring items between displayed windows
Inventor: RICH CHRISTOPHER JACOB
IPC: G06F3/0482
Filed: 1999-12-10
Granted: 2003-03-25
Abstract: A computer implemented method is described for enabling a user to transfer, via a graphical user interface, an item from one displayed window to another displayed window. Initially, a first window is displayed with an item to be moved and a second window is displayed with one or more destinations to which the item can be moved.  Thereafter, the user selects the item to be moved, causing a further window to be displayed which includes one or more commands, one of which manifests a movement action. Upon selection of the movement command, the graphical interface displays a list of destinations with which the item to be moved can be associated by actuating the movement command.  Thereafter, responding to a selection of one of the displayed destinations, the computer which operates the graphical view user interface associates the item being moved with the selected destination and alters the display so that at least one of the displayed windows manifests the movement action.

Abstract: A toilet bowl rim block dispenser comprises a body (1) for receiving a block of material (14) to be dispensed and a hook (2) by which the dispenser may be attached to the rim of a toilet bowl. The body (1) is provided with apertures (3) by which water may enter or leave the body (1) when the toilet is flushed. The body comprises a thermoplastic moulding, having a first part which comprises the hook (2) and a first body part (4) which is linked to a second body part (5) by a hinge (6) moulded into the body. Body part (4) carries a single projecting lug terminating in a barb (7). When the first and second body parts are brought together by rotation about hinge (6), the lug and barb (7) engage an aperture (8) in the second body part (5). The body is opened by manually depressing barb (7) so as to disengage it from aperture (8), which is normally prevented by locking means (9), connected to body part (5) by pairs of ribs (10, 11). When no block (14) is present in the dispenser, pressing the lower end (13) of the locking means (9) causes it to move inward, while the upper end (12) moves outward relative to the dispenser, so that downward movement of the barb (7) is no longer restrained, and the barb may be depressed, permitting opening of the body. When a block (14) is present in the dispenser, pressing the lower end (13) of the locking means (9) is inhibited by the presence of the block, and the body may not be opened.
