Title: Method and device for entropy transfer with a thermodynamic cyclic process
Inventor: ERTLE THOMAS
IPC: F02G1/04
Filed: 1998-09-23
Abstract: The invention relates to a method and device for entropy transfer, whereby a periodic cyclic process is created inside a pressurized container by periodically exchanging working substance(s) using valves at different pressures and by periodically modifying partial volumes defined by regenerators with or without the use of a compression device. The transformation of mechanical energy by exchanging a working substance at different pressures makes it easier to integrate other partial systems and to substantially modify the temperature of at least one working substance flow by coupling a thermodynamic cyclic process to heat energy transport, heat energy storage or the construction of a simple effective solar collector system wherein optical concentration, translucent insulation and translucent insulation cross-flow are combined in an effective manner. The invention can be used for solar energy or heat sources or to supply local pumping capacity requirements and provide mechanical actuation, electrical energy, heat, cold, cleaning or separation and chemical or physical modification of at least one substance.

Patent CA-2308825-A1 (CA)
Inventor: GOLDSTEIN YURI
IPC: H04J3/12
Filed: 2000-05-18
Abstract: The receiver of a PCM modem utilizes the V.90 TRN1d training signal for detecting whether any of the six slots of the received signal may be subject to alternating robbed bit signaling (ARBS), and what the alternating robbed bit signaling pattern may be.      This is accomplished by accumulating the received level over a plurality of frames for each slot and by comparing the received levels for each slot to an average level for that slot. If the difference between the received levels and the average levels exceeds a threshold, the slot is determined to be subject to ARBS.      Where a slot is subject to ARBS, DIL sequence signals for frames of the alternating robbed bit signaling slot having LSB=0 and LSB=1 are accumulated separately (if available) in order to generate two translation tables (TRT0, TRT1) for that slot. Where the DIL sequence is found only in the frames having the alternating robbed bit signaling slot having LSB=0 or having LSB=1, only one translation table can be generated. Different algorithms are provided for designing a constellation for the alternating robbed bit signaling slot depending on (a) whether two translation tables were generated for the slot, (b) whether the frame-to-TRT correspondence is known, and (c) where only one translation table is generated, whether the translation table generated was TRT0 or TRT1.

Title: Edge cut to increase effective width of insulation sheet and method of forming the same
Inventor: CUNNINGHAM RICHARD NAPOLEON
IPC: E04D13/16
Filed: 2000-08-17
Abstract: An insulation sheet for insulating a wall, floor, ceiling or roof cavity is flexible, compressible and resilient and has lateral edges extending the length of the sheet. The lateral edges of the sheet are formed with contours along the lengths of the lateral edges, which with the flexibility, compressibility and resilience of the insulation sheet, increase the effective width of the sheet, relative to a conventional insulation sheet of the same length, width, thickness and density with straight lateral edges extending perpendicular between the major surfaces of the conventional sheet, with no or substantially no increase in the amount of insulation material forming the sheet relative to the insulation material used in the conventional insulation sheet. The contours of the lateral edges are formed by reciprocally oscillating cutting blades in a direction transverse to the feed of a sheet past the cutting blades and/or by placing the cutting blades at an angle other than perpendicular to the major surfaces of the sheet being fed past the cutting blades or by synchronously moving the cutting blades back and forth between a negative and a positive angle as the insulation sheet is fed past the cutting blades.

Patent CA-2319416-A1 (CA)
Title: Natural resin formulations
Inventor: FREEL BARRY
IPC: C08H8/00
Filed: 1999-01-29
Abstract: This invention is directed to a method of preparing a natural resin by liquefying wood, bark, forest residues, wood industry residues, or other biomass using fast pyrolysis in order to produce product vapours and char.  Following removal of the char from the product vapours, a first set of compounds are removed from the product vapours by rapid quenching in order to obtain a remaining selected product vapour from which a natural resin is obtained. The natural resin comprises a total phenolic content from about 30 %  to about 80 % (w/w), and is further characterized as having a pleasant smoky odour. The natural resin has surprisingly been found to be suitable for use within adhesive formulations without requiring any further extraction or fractionation procedures. Adhesives comprising up to 60 % natural resin have been prepared and tested in board production and found to exhibit similar properties associated with commercially available resins. The natural resin may substitute for phenol, or for both phenol and formaldehyde within phenol-containing resins. Similarly, the natural resin can replace a substantial part of the components within urea-containing resins.

Filed: 1998-12-11
Abstract: It has been found possible to separate catalytically-active aminophosphonium catalysts from mixtures composed predominately of aminophosphonium catalyst residue(s) and heavy ends form a halogen exchange reaction conducted in an aprotic solvent/diluent by extracting such mixtures with a neutral or acidic aqueous extraction solvent medium. Various ways of isolating form the halogen exchange reaction product mixture a mixture composed predominately of aminophosphonium catalyst residue(s) and heavy ends are described. Halogen exchange processes in which the catalytically-active aminophosphonium catalysts are separated for reuse are also described. Since aminophosphonium catalysts are expensive, the present process technology fulfills a need which has existed for an effective way of recovering such catalysts in catalytically active form enabling reuse of such materials, especially as halogen exchange catalysts.

IPC: G01V3/30
Filed: 2000-11-30
Abstract: Methods and apparatus for making directional measurements of earth formations surrounding a borehole. New antenna coil shield designs are utilized to provide selective attenuation of at least one electromagnetic energy field component as the component interacts with the shield. The new shields are implemented in several downhole tool configurations to provide azimuthally focused formation measurements. In effect, the new shield filters interacting electromagnetic energy field components to pass those components corresponding to a magnetic dipole oriented at an angle from the tool axis. The shields thereby alter a coil's envelope of influence to electromagnetic energy. The new shields also form part of a system for making directional measurements while drilling.

Title: Rf ablation apparatus having high output impedance drivers
Inventor: SHERMAN MARSHALL L
IPC: A61B18/12
Filed: 1999-04-28
Abstract: An apparatus for delivering energy to a biological site includes a catheter having a plurality of electrodes positioned proximal the biological site. A power control system supplies power to each electrode. Where an electrode or group of electrodes is turned off, the power control system provides a high impedance to the turned off electrodes so that substantially no current flows to those electrodes from other electrodes that may remain on. This permits the electrodes turned off to cool. The power control system may permit control over the phase and duty cycle of the power applied to the electrodes and may permit individual control over the power provided to each electrode. A backplate is also positioned proximal the biological site so that the biological site is interposed between the electrodes and the backplate. Where a unipolar/bipolar approach is used with the backplate, the power control system controls the phase angle of the power applied to the electrodes so that the current flows between the electrodes and between the electrodes and the backplate.
