Title: Ignition System for Internal Combustion Engines
Inventor: SAKAI KATSUHIRO
IPC: F02P3/08
Filed: 1997-01-22
Abstract: An ignition system for an internal combustion engine is disclosed.  The ignition system includes an ignition capacitor having one end terminal connected to an anode of a thyristor of which a cathode is connected to an ignition coil, and an opposite end terminal of the ignition capacitor is connected to ground.  Further, the cathode of a diode is connected to the anode of the thyristor, and the anode of the diode is connected to the cathode of the thyristor.  With this configuration, charge and discharge of the capacitor for ignition are repeated with repeated inversion in polarity of an electric charge accumulated in the ignition capacitor.  As a result, a spark discharge can be repeatedly achieved across the ignition plug and it is therefore possible to achieve a stable AC arc in accordance with the DC-CDI method.

Patent CA-2198959-A1 (CA)
Inventor: SOMMER RONALD G
IPC: G01N33/53
Filed: 1997-03-03
Abstract: Disclosed is a method for determining the concentration of an analyte in a liquid test sample. The method involves the use of colloidal sized metal particles, which exhibit a spectral response in the agglomerated state which is detectably different than in their unagglomerated state, which bear specific binding partners for the analyte in question on their surface. The specific binding partner treated colloidal particles are combined in a buffered, aqueous medium with a destabilizer material capable of destabilizing the specific binding partner-colloidal particle conjugates thereby permitting the particles to agglomerate. Also included in the liquid medium is a polymer bearing multiple analyte or analyte analog molecules along its surface which serves to protect the specific binding partner coated metal particles from dissociation by the destabilizing agent. Analyte added to the medium, typically in the form of a fluid test sample, competes for the specific binding partner and thereby decreases the amount of protection afforded by the analyte or analyte analog bearing polymer which permits unprotected colloidal particles to agglomerate and provide a detectable spectral response. The magnitude of the change in spectral response is directly proportional to the concentration of analyte in the fluid test sample.

Title: Cyclodextrin glycosyl transferases for producing .gamma.-cyclodextrin
Inventor: SCHULZ GEORGE E
IPC: C12N1/21
Filed: 1997-03-13
Abstract: CGTases, which, when converting starch or starch-like substrates to CD, produce .gamma.-CD to an increased extent and still exhibit at least 60% of the specific total CGTase activity of the starting CGTase which was used for preparing the enzyme concerned.  The amino acid sequences differ from the amino acid sequences of known CGTases by the deletion of at least one amino acid from the region from amino acid position 155 up to and including amino acid position 195, where position 1 of the protein sequence is the beginning of the signal peptide of the CGTase and the deletion brings about the increase in the .gamma.-CGTase activity of the protein.

Abstract: L'invention est constituée par des méthodes et des appareils servant à déterminer la position d'une station mobile dans un système de communication sans fil. Les stations mobiles de ce système sans fil sont dotées d'un circuit générateur d'échos inaudibles qui reçoit un signal horodateur d'émission transmis sur un canal de synchronisation par une station de base et qui traite ce signal pour produire un signal horodateur de réception. Le circuit générateur d'échos inaudibles transmet ce signal horodateur de réception à la station de base sur une porteuse d'échos parasites décalée par rapport à l'une des porteuses de données du système. La station de base traite les signaux horodateurs d'émission et de réception pour calculer une première distance, reçoit une deuxième et une troisième distances correspondantes calculées par deux autres stations de base du système qui reçoivent la porteuse d'échos et son signal horodateur et qui traitent la première, la deuxième et la troisième distances pour déterminer le vecteur indiquant la position de la station mobile. La station de base traite ensuite ce vecteur pour en déterminer le relèvement et convertit le résultat en coordonnées de latitude et de longitude de la position de la station mobile. Le circuit générateur d'échos inaudibles de l'invention permet de déterminer la position d'une station mobile dans le système de communication sans fil sans accroître le coût, les dimensions, le poids et la consommation d'énergie de cette station de façon significative, sans nécessiter d'interface utilisateur multicouche et sans dégrader la qualité des signaux vocaux.
Patent CA-2226688-A1 (CA)
Title: Apparatus and method for dual-zone well production
Inventor: MILLS ROBERT A R
IPC: E21B43/12
Filed: 1998-02-16
Abstract: A method and an apparatus for producing fluid hydrocarbons through a single production tubing string from first and second zones which communicate with a hydrocarbon wellbore is disclosed. The apparatus includes a packer positioned in the wellbore for selectively preventing a flow of fluids through the wellbore from the first zone to the second zone, a production tubing string that extends through the wellbore and is in fluid communication through the packer with the second zone, and first and second pumps for displacing fluid through the production tubing string. The second pump displaces fluid from the lower zone into the production tubing string. A perforated joint is placed in the production tubing string between the second and the first pump. The second pump has a given displacement capacity at a given speed and is of a type that inhibits a flow of fluid in either direction through the pump when it is not pumping fluids from the second zone. The first pump is positioned in the production tubing above the second pump and has a predetermined displacement capacity at the pumping speed which is greater than the capacity of the second pump by the capacity desired to be produced from the first zone. The lower pump meters fluid from the lower zone and the upper pump produces fluids from the well so that both zones are produced simultaneously without fluid loss from either zone regardless of which zone has lower pressure. The means for controlling fluid communication through the packer depends on which zone has higher pressure. The advantage is a simple inexpensive apparatus for efficiently producing hydrocarbons from two production zones with pressure differentials without loss of fluid to either zone. Hydrocarbon production from the well is thereby maximized, stabilized and potentially prolonged.
