Patent CA-2240885-C (CA)
Inventor: JABAJI ISSAM
IPC: H02J7/16
Filed: 1998-06-17
Granted: 2001-01-16
Abstract: A microprocessor-based voltage regulator for an alternator reduces battery drain by removing current from the field coil during times when the alternator is not rotating, as indicated by an AC Sense signal responsive to one of the windings of the alternator prior to rectification. The field coil switch is controlled by the microprocessor to one of four duty cycles to provide effective voltage regulation with a minimum of additional hardware. The microprocessor generates a warning signal in the event of a non-standard operating condition such as drifting voltage regulation, disconnected batteries, or thermal limits that approach shut down.

Title: Optical filter fabrication method and apparatus, optical filter, fiber holder with spiral groove, and phase mask
Inventor: NOMOTO TSUTOMU
IPC: G02B6/36
Filed: 1998-07-06
Granted: 2003-06-24
Abstract: An optical filter is manufactured by placing a photosensitive optical fiber in a spiral arrangement on a fiber holder, preferably having a spiral groove for holding the fiber, and exposing the fiber to ultraviolet light through a phase mask having a spiral diffraction grating, forming an in-fiber Bragg grating.  The fiber can be conveniently scanned by an ultraviolet beam as the fiber holder and phase mask turn on a rotating stage.  The fiber can be compactly packaged between the fiber holder and a cover.  The fiber holder and cover can be formed by coating a substrate with layers of polymer material, the spiral groove being formed by photolithographic patterning of one of the layers.

Abstract: A coarse particle kaolin clay is provided having an average Stokes equivalent particle diameter of about 4.5 - 6.0 microns, a BET surface area of about 8 - 11 m2/g, and preferably having a median Malvern particle size of about 9.0- 10.5 microns as determined by laser light-scattering measurement and a high aspect ratio preferably of about 12-14 as determined by Sphericity Model calculations. The coarse particle kaolin clay provides low viscosity build, good reinforcement properties and excellent surface finish qualities as a filler in thermoset composite materials, such as polyester molding compounds, and also provides excellent pigmenting properties in paints and industrial coatings. Preparation of the coarse particle clay involves blunging and degritting a crude kaolin clay, conducting three separate centrifugation steps with the desired product stream being, in sequence, the coarse underflow clay from the primary centrifuge, the coarse underflow from the secondary centrifuge, and then the fine overflow from the tertiary centrifuge, followed by magnetic separation, screening, chemical leaching, drying and milling to produce a kaolin clay product having the above-described physical properties and performance characteristics.

Title: Apparatus for measuring a gas value
Inventor: THURSTON ROBERT RICHARD
IPC: G01K11/24
Filed: 1997-04-21
Granted: 2003-02-11
Abstract: An energy meter (2) comprises a combustible fuel gas inlet (48) and a fuel gas outlet (50) and a central tube (12) along which the gas flows in travelling from inlet to outlet. Ultra-sound transducers (52 and 54) and a control (56) comprising computer means form a system whereby the speed of ultra-sound signals travelling through the gas between the transducers can be measured and utilised in the control to calculate the volumetric amount of gas which has passed through the meter. The ultra-sound signals pass through apertures (33 and 38) in the walls (24, 26) of chambers (32, 34) containing the transducers.  Another ultra-sound transducer (66) in the chamber (32) and connected to the control (56) acts as an emitter and receiver of ultra-sound signals reflected by reflectors (68 and 70). These signals travel through the fuel gas in chamber (32) and their attenuation is observed and measured by the control when they are received by transducer (66). The measured attenuation is used by control (56) to derive the calorific value and/or Wobbe index of the gas, and the control uses the volumetric amount of gas and the calorific value and/or Wobbe index to derive the amount of energy provided by the supply of the gas.

Title: Method and device for configuring a link
Inventor: LUDWIG REINER
IPC: H04L12/28
Filed: 1999-01-11
Granted: 2005-06-28
Abstract: The invention relates to method and device for improving the link configuration speed of high-latency links, such as circuit switched links or satellite links, that use chatty protocols, which require sequential configuration phases, such as standard PPP in accordance with RfC 1661. In the initial link configuration phase, a standard LCP packet is sent out, followed by at least one masked packet that will be discarded silently by a peer operating in accordance with the standard protocol, but whose contents will be processed by a peer operating in accordance with the invention. The initial standard LCP packet produces compatibility with the standard protocol, whereas the sending of masked packets containing configuration information (PAP, CHAP, ICPC, etc.) allows two peers operating in accordance with the invention to accomplish the configuration phases in parallel, such that a link can be configured and ready to transmit network level packets, such as 1P packets, much more quickly than with the standard protocol, such as PPP.

Abstract: Procédé de production et d'amplification d'ADN circulaire fermé à séquence spécifique in vitro dans un système acellulaire. Avant le procédé selon la présente invention, l'ADN circulaire fermé pouvait être amplifié seulement in vivo dans des cellules hôtes appropriées. Le principe du présent procédé est l'inclusion d'une ligase thermostable dans la réaction de PCR. Ce procédé est qualifié de ligature pendant l'amplification (LDA), lors duquel les brins d'ADN complètement étendus sont ligaturés par la ligase et utilisés comme matrices pour l'amplification ultérieure. De l'ADN circulaire fermé ayant une séquence spécifique peut être sélectivement amplifié de manière exponentielle par l'utilisation de deux amorces spécifiques à des séquences dans la réaction de LDA. De plus, une ou plusieurs mutations spécifiques à des sites peuvent être introduites dans un ADN circulaire fermé par l'utilisation d'une ou plusieurs amorces mutagènes dans la réaction de LDA. Diverses ADN polymérases et ligases thermostables peuvent être utilisées pour l'amplification LDA. Toute orientation et position d'amorce, tant vers l'intérieur que vers l'extérieur, peut être utilisée dans l'amplification LDA, pour autant qu'il existe au moins une amorce complémentaire pour chaque brin de l'ADN circulaire. Ledit procédé trouve des applications dans les domaines de la mutagenèse, du clonage, de la détection d'ADN, de la modification d'ADN, de la recherche de gènes, de la thérapie génique et de la production acellulaire d'ADN.
