Patent CA-2246404-A1 (CA)
Inventor: SHIMADA KOICHI
IPC: H04N3/15
Filed: 1998-08-26
Abstract: Two plane parallel plates, orthogonally intersecting each other, are provided in front of a CCD device.  The plane parallel plate is supported by its two ends which are deviated from an optical path.  Each end of the plane parallel plate includes an armature made of soft electromagnetic iron, and two electromagnets are provided in the optical axis direction, while sandwiching each armature.  By the on/off state of the two electromagnets, the armature can control the optical device in three angled positions, thus the optical device can have three shift positions with respect to the optical axis.  Therefore, by virtue of the optical devices, an optical path can be determined by selecting a shift position of said optical device from nine shift positions (3 x 3).

Patent CA-2254828-A1 (CA)
Inventor: ZHANG YING
IPC: C12Q1/68
Filed: 1997-05-23
Abstract: Disclosed are methods, probes, primers and kits for identifying pyrazinamide-resistant mycobacteria. These methods can be used to distinguish M. bovis from M. tuberculosis, as well as to identify additional pyrazinamide-resistant mycobacteria. Also disclosed are methods for treating mycobacterial infections by expressing a pncA gene in mycobacteria that infect a mammal, and treating the mammal with pyrazinamide. The invention derives from the discovery of that the molecular basis for pyrazinamide resistance is an alteration in the pncA  gene of mycobacteria. The detection of such an alteration is an indicator of PZA-resistant mycobacteria.

Title: Avalanche transceiver
Inventor: KAMPEL GERALD
IPC: A63B29/02
Filed: 1998-11-30
Abstract: An improved rescue device for locating persons buried by avalanches operates in either a transmit mode or a receive mode. A first belt terminator is lockably engagable with a first belt terminator receptor on a case, and is associated with a power switch. The power switch switches between a power on position and a power off position in response to the engagement and disengagement of the first belt terminator with the first belt terminator receptor, and preferably is also independently manually operable. A second belt terminator is lockably engagable with a second belt terminator receptor on the case, and is associated with a mode switch. The mode switch toggles between a transmit mode position and a receive mode position, and preferably is also independently manually operable. A signal processing system generates a visual display which provides graphic information to expedite searching.      Prompt icons are displayed when a coarse search or a pinpoint search should be conducted, when the stage of a multistage amplifier should be changed, or when the rescue device needs to be reoriented to obtain maximum signal strength. Preferably, the signal processing system also displays the signal strength as a bar graph and displays an estimated distance to the buried transmitter.

Title: Gas turbine combustor
Inventor: MANDAI SHIGEMI
IPC: F23D14/02
Filed: 1999-02-04
Abstract: A combustor enabled to prevent a hot premixed flame from flowing back into a main swirler zone.      The combustor comprises a pilot nozzle 02 arranged at the central portion of an inner cylinder 01 opened at its end into a combustion chamber 018 and including a plurality of main nozzles 03 arranged around its outer circumference. Along the outer circumference of a flame holding cone 014 for igniting a fuel F injected from the main nozzles 03, there are disposed elliptical extension pipes 016 of an elliptical section shape which are extended from the fronts of the main nozzles 03 to have openings at the axial position of the opening of the flame holding cone 014.      As a result, the hot premixed flame 013 does not flow back to the main swirler zone 015 of the circumferential edges of the openings of the main nozzles 03, so that the mixing between the fuel F and an air flow A can be improved to reduce the NOx emission while eliminating the burning of a base plate 04 and the main nozzles 03.

Patent CA-2268577-A1 (CA)
Title: Tubular container with heat seal having an inner and outer bead and method of manufacturing said container
Inventor: WILLIAMS ALAN D
IPC: B31B50/64
Filed: 1999-04-12
Abstract: A method of manufacturing multi-ply tubular containers for food products is provided including the steps of applying an aqueous adhesive to a surface of a paperboard body ply and then heating the aqueous adhesive to evaporate part of the water content and render the adhesive substantially tacky. The body ply and a polymeric liner ply having a moisture barrier layer are then either fed to a shaping mandrel from opposite sides and bonded together as the container is formed on the mandrel or are first passed through a nip to adhere the liner ply to the body ply and then wrapped around the mandrel as a laminate to create the tubular container. Accordingly, an advantageous tubular container can be manufactured having a body ply formed of paperboard which is wrapped into a tubular shape to define an inner surface. The body ply defines a predetermined circumferential length before being wrapped which corresponds to one revolution of the body ply when wrapped in a tubular shape. A polymeric liner ply is adhered to the inner surface of the body ply and defines a circumferential length equal to that of the body ply prior to being wrapped. Accordingly, the liner ply is circumferentially compressed when the body ply is wrapped into the tubular shape and advantageously has a wrinkled surface finish after being wrapped which is caused by the circumferential compression of the liner ply. Another feature of the invention is a sealed composite container having an end seal formed by a pair of inner and outer beads of a heat flowable polymer forming a part of the liner and membrane-type lid.

Abstract: This newest invention is a way of developing the greatest amount of torque or forces known to man. It works on a principle of one force acting in two different directions to produce them into one huge force acting like a double fulcrum at the same speed or revolutions per minute (RPM). The increased torque will avoid pollution and fuel expenses. It is possible to use the excess energy in all fields by transforming its form.      This means we have perpetual motion.
