Patent CA-2315513-A1 (CA)
Inventor: SHEA JOHN JOSEPH
IPC: H02H1/00
Filed: 2000-08-11
Abstract: Arcing faults in electric power systems, such as switchgear, are detected by gathering light from components in the system and splitting the gathered light into two beams. The first beam is passed through a first narrow band filter to extract a wavelength characteristic of arcing in the material of the selected component, such as the copper in the switchgear conductors. The second beam is passed through a second filter having a narrow bandwidth, not including the characteristic wavelength. The extracted light signals are converted to a sensed light electrical signal and a background light electrical signal, respectively, by photodiodes and compared. If the sensed light electrical signal exceeds the background light electrical signal by a selected threshold, an output device such as a trip solenoid is actuated.

Title: Method and apparatus for monitoring and control of laser emission wavelength
Inventor: DUNN PAUL E
IPC: H01S5/0687
Filed: 1999-02-18
Abstract: An apparatus for monitoring and controlling the wavelength of laser radiation includes at least one optical filter for receiving laser radiation and for transmitting and reflecting first and second filtered beams, respectively.  Alternatively, the first and second beams may be transmitted by separate filters (32, 34). The beams are filtered according to respective first and second spectral filter functions that cross at least one crossing wavelength.  A beam comparison element (20) compares the first and second filtered beams (36,38) and produces an error signal (22) representative of the deviation of the wavelength of the laser radiation from a set-point wavelength. The beam comparison element (20) can include first and second optical detectors (40, 42) and error signal (22) by taking a ratio or the difference of the signals detected by the detectors. Varying the angle of incidence of the laser radiation upon at least one optical filter varies the spectral filter function of that filter for selecting or varying the operating wavelength of the laser (12). A laser wavelength controller (24) can receive the error signal (22) for stabilizing or tuning the wavelength of the laser radiation. Several embodiments of the invention are disclosed.

Title: Method for cacheing configuration data of data flow processors and modules with a two- or multidimensional programmable cell structure (fpgas, dpgas or similar) according to a hierarchy
Inventor: MUNCH ROBERT
IPC: G06F12/0813
Filed: 1999-02-25
Abstract: Up until now, a central and global unit have been integrated into one module which processes all of the configuration requests. The invention provides for a plurality of active units which can take over this task. These units are arranged in a hierarchy. A request from the lowest level is only transferred to the next highest level if the request cannot be processed. The highest level is connected to an internal or external higher-order configuration memory which contains all the configuration data ever required for this programme run. The tree structure of the configuration units enables a kind of cacheing of the configuration data. The configurations are mainly accessed locally. In the worst case scenario, a configuration has to be loaded from the higher-order configuration memory in case the relative data are not available in any of the CTs (configuration tables) in the hierarchy.
Patent CA-2322419-A1 (CA)
Inventor: RICHTER PETER
IPC: G01S17/931
Filed: 1999-03-09
Abstract: The invention relates to a special light source which produces a horizontal strip of light. Said strip of light is reflected by objects in the vicinity of the sensor system and conducted to a photoelectric converter by a special imaging device. Said imaging device is configured in such a way that objects situated further away are represented as being somewhat further apart so that an ordinary objective with linear resolution can obtain better position resolution of objects situated further away from the sensor system over the entire imaging area. Advantageously, light-emitting diodes are provided on the optical axis of a cylindrical mirror as the light-emitting elements. The electrical signals emitted by the photoelectric converter are evaluated by an evaluation unit in relation to their position. Using triangulation, said evaluation unit then determines how far away the objects which reflected the light are situated.

Patent CA-2330214-A1 (CA)
Title: Portable ground thawing apparatus
Inventor: OLSON LAWRENCE BERNARD
IPC: E01H5/10
Filed: 2001-01-04
Abstract: The invention is a portable ground thawing device using a shallow rectangularly shaped box-like apparatus (or thaw body) that is open-ended on the side that  would normally form the floor of the thaw body. This open-ended box is constructed  with a high degree of insulating value and is designed to trap heat against the surface of frozen ground while also including a reflective inner surface. The heating requirements are supplied by the use of an externally mounted radiant propane heater that  is commonly available in the marketplace today. This attachment is built into o ne of the short vertical walls on the end of the thaw body by placing the burner eleme nt of the radiant heater in the most outward opening of a vented heat transfer tube. T he vented heat transfer tube is a cylindrical opening that passes from the outside of the thaw body so as to leave an air gap to allow for the free flow of air from inside the thaw body to the outside by the burner. This free flow of air to the heater enhances the efficiency of the radiant heater and therefore increases the operational effectiveness of the invention.

Title: Time-wavelength multiple access optical communication systems and methods
Inventor: GRUNNET-JEPSEN ANDERS
IPC: H04B10/12
Filed: 1999-08-10
Abstract: Methods and apparatus for optical communication are disclosed. An optical data stream (220) is encoded (201) to produce an optical data stream having a predetermined time-wavelength spectrum. Two or more encoded (201) data streams are combined in a transmission medium (e.g., optical fiber) and the combined data stream is decoded with decoders corresponding to the encoding of the data streams, producing decoded outputs. The decoded outputs include a portion corresponding to a selected data stream as well as a portion corresponding to unselected data streams (crosstalk). A nonlinear detector receives the decoded outputs and rejects crosstalk. Coders produce temporal delays and phase shifts specified by a time-wavelength code for the spectral components of an input optical signal. Some coders convert optical signals encoded with a first time-wavelength code into an output corresponding to a second time-wavelength code. Temporal delays and phase shifts can be selected to compensate for dispersion in a transmission medium. Coherent coders are, provided in which the phase shifts produced on the spectral components of an optical signal are controlled within about one half of the wavelength of the spectral component.
Patent CA-2342136-A1 (CA)
Inventor: WATSON RICHARD WILLIAM
IPC: C01B17/04
Filed: 2001-03-27
Abstract: A feed gas stream containing hydrogen sulphide is subjected in a furnace 6 to reactions in which part of the hydrogen sulphide is burned to form sulphur dioxide, and is which the sulphur dioxide reacts with residual hydrogen sulphide to form sulphur vapour. The sulphur vapour is condensed from the gas stream exiting the furnace 6 in a sulphur condenser 16. Residual sulphur dioxide is reduced back to hydrogen sulphide by hydrogen in a reactor 22. Water vapour is removed from the reduced gas in a quench tower 28 to form a water vapour-depleted gas stream.  One part of the water vapour-depleted gas stream is sent to an adsorber vessel 30 in which hydrogen sulphide is absorbed in an absorbent. The resulting hydrogen sulphide - depleted gas stream is vented from the vessel 30 as a purge stream. Another part of the water vapour - depleted gas stream and a hydrogen sulphide -rich gas formed by desorbing hydrogen sulphide from the absorbent in a vessel are returned as recycle streams to the furnace 6.

Methods of crossing or displacing a vascular occlusion are further provided that include the positioning of a vascular catheter having at least one hinged spreading member positioned at the distal region of the catheter that is responsive to directed force along the longitudinal axis of the catheter. A directed force is applied to the actuator in order to deploy the spreading member and displace a vascular occlusion creating a path to permit the passage of a guidewire or device therethrough.
Patent CA-2345990-A1 (CA)
Title: Process for the preparation of ethyl acetate
Inventor: COLLEY STEPHEN WILLIAM
IPC: C07C67/44
Filed: 1999-09-29
Abstract: Ethanol is dehydrogenated in the presence of hydrogen over a dehydrogenation catalyst, for example, a copper on silica catalyst. The liquefiable products present in the resulting intermediate reaction product mixture are selectively hydrogenated over a suitable catalyst, such as 5% ruthenium on carbon, so as selectively to hydrogenate reactive carbonyl-containing by-products to the corresponding alcohols.  Butan-2-one and n-butyraldehyde, which would otherwise cause difficulties in purification of the ethyl acetate product, due to the proximity of their boiling points to that of ethyl acetate, are thereby hydrogenated to 2-butanol and n-butanol respectively. A two stage distillation procedure is then used to purify the selectively hydrogenated product. The first distillation zone is typically operated at less than about 4 bar (4 × 10 5 Pa) absolute, while the second distillation zone is typically operated at a pressure of from about 4 bar (4 × 10 5 Pa) absolute to about 25 bar (2.5 × 10 6 Pa). A first distillate of ethyl acetate, ethanol and water produced in the first distillation zone is redistilled in the second distillation zone, thereby producing a bottom product comprising, typically, from about 99.8 mol % to about 99.95 mol % ethyl acetate and an overhead second distillate, which has a different composition from that produced in the first distillation zone and which is returned to the first distillation zone, preferably at a point above the feed point for the liquefiable products of the selectively hydrogenated reaction product mixture.
