Patent CA-2283899-A1 (CA)
Inventor: FARLEY PETER
IPC: H01F37/00
Filed: 1998-03-18
Abstract: An electrical choke comprises a magnetic amorphous metal core having, in combination, a distributed gap and a discrete gap. The amorphous metal is an iron based, rapidly solidified alloy. The distributed gap configuration is achieved by subjecting the magnetic core to a heat treatment, causing partial crystallization of the amorphous alloy. Such partial volume crystallization reduces the permeability of the magnetic core from several thousands to a value ranging from 200 to 800. The discrete gap is introduced by cutting the core and inserting a spacer. Depending on the width of the gap and the value of the annealed permeability, effective permeabilities in the range of 200 to 40 can be achieved. Advantageously, the reduced permeability magnetic core maintains its initial permeability under DC bias field excitation and exhibits low core loss, making it especially suited for use in power factor correction applications.

Patent CA-2290342-A1 (CA)
Inventor: BACKMAN JOHAN
IPC: H03M13/45
Filed: 1998-05-15
Abstract: The present invention relates generally to the detection of bits which are protected by repetition, and which, along with their repetitions, have associated soft values available which give a measurement of the reliability of their received values. In particular, the present invention may be used in speech encoding in the GSM mobile communications system, and more particularly to the detection of those class 2 bits called pulse5 bits which are not protected with channel coding. In enhanced full rate (EFS) transmission in GSM  there are 4 bits called pulse5 bits. These pulse5 bits are duplicated twice, giving three bits for each original bit, for a total of twelve pulse5 bits.  These bits have associated soft values, a probability measure of their reliability, that are produced by the equaliser. These associated soft values are then used in the present invention to improve detection of these pulse5 bits over the state of the art which detects the pulse5 bits only using a majority decision among the 3 bits generated, without using their associated soft values.

Title: Device for identification of need to replace synthetic fiber ropes
Inventor: DE ANGELIS CLAUDIO
IPC: D06H1/00
Filed: 1999-12-06
Abstract: To identify the need for replacement of stranded synthetic fiber ropes (1), preferably ropes of aramide fiber, a torsionally neutral rope construction of load-bearing fiber strands (2, 3, 4, 5) is obtained by having at least two layers of strands (7, 14) laid together in opposite directions so that the torsions in the layers of strands (7, 14) due to their lay compensate each other. If the layers of strands (7, 14) become weakened by unequal amounts due to wear or external influences, when the rope (1) is under load and running operationally it begins to twist about its longitudinal axis (20). The twisting of the rope (1) can be made visible by means of various measures.      In one embodiment a mark (11) along the length of the rope indicates twisting of the rope and thereby serves to provide visual identification of the need for its replacement.

Title: Multiple resistive sensors for a coriolis effect mass flowmeter
Inventor: ZOLOCK MICHAEL J
IPC: G01F1/84
Filed: 1998-06-02
Abstract: A circuit for utilizing multiple resistive sensors (109, 110) and in particular resistive temperature sensors while minimizing the number of conductors (308, 309, 310) necessary to measure the multiple sensors. The multiple sensors are connected in series and the voltage is measured at each node in the series connection of sensors. A switching device (F0) then opens to remove one of the sensors from the voltage supply (5v) allowing a measurement to be made of the resistance of the conductor between the temperature sensors and a remote transmitter (20). The measured sensor resistances are then compensated with the measured conductor resistance to obtain a conductor-length compensated resistance for each of the multiple resistive sensors.

Title: Process for upgrading heavy crude oil production
Inventor: OHSOL ERNEST O
IPC: C10G33/04
Filed: 1998-10-08
Abstract: A process for upgrading heavy crude oil production is described which involves adding a diluent, or solvent, which is a light hydrocarbon to reduce the viscosity and specific gravity of the crude oil being processed. After dilution, the emulsions in the crude are broken and the separation of the crude into the components follows, aided by a second injection of diluent. This upgrades the crude and enhances the amount recovered for processing at a refinery. A high asphalt content of a heavy crude can also be tolerated in the practice of this invention resulting in environmentally-benign solids and water exiting a process which due to the modularization of equipment can be practiced at the well-head itself.

Title: Automated send to embedded fax/e-mail address
Inventor: UBOWSKI RICHARD M
IPC: H04M1/2755
Filed: 2000-11-22
Abstract: Embedded writing or typing in a fax document or white board presentation are detected in a predetermined region of the document, recognized and converted into textual data corresponding to the fax telephone number or e-mail of the recipient of the document. The fax telephone number is automatically dialed without requiring the user to input the telephone number or even select a speed dial telephone number, although the use of confirmation of the scanned and textually converted fax telephone number or e-mail is within the principles of the present invention. In a first embodiment, the present invention adds the capability to a fax machine to scan the first page of the outgoing fax (e.g., the cover page) for detection and recognition (e.g., optical character recognition (OCR)) of the recipient's fax number and automatically dials it if found. Moreover, the sender's identification (e.g., telephone number and/or name) can also or alternatively be automatically scanned and determined to replace, add to, or otherwise overwrite the default header information programmed into the sending fax machine. In this way, the fax machine can automatically dial the sender's fax number, and/or imprint the customized header on the outgoing faxed pages with the sender's telephone number and/or name. A look-up table may be maintained to correlate specific names of individuals or businesses with specific fax telephone numbers or e-mail addresses. In another embodiment, a scanning white board allows a destination telephone number or e-mail address to be written in a predetermined area, and either periodically or upon demand the white board is scanned, and the image automatically faxed or e-mailed to the designated destination.
