Patent CA-2226744-A1 (CA)
Inventor: MARTYAK NICHOLAS M
IPC: C23C18/36
Filed: 1998-02-16
Abstract: This invention relates to aqueous solutions containing Ni cation and hypophosphite anion which have a Ni cation concentration greater than 36 grams /liter.  Such solutions have utility in electroless nickel plating baths and processes as make-up solutions and replenishing solutions.  The increased concentration of Ni cation results from the addition of the nickel salt of an alkyl sulfonic acid to the solution.

IPC: H02K7/18
Filed: 1996-08-19
Abstract: A permanent magnet rotor alternator is disclosed having a one-piece, rotor hub/flywheel/starting gear. Three high permanence ceramic permanent magnets provide a rotor having a contiguous ring of twelve alternating poles which allows for higher alternator efficiency. The magnets are ceramic and are adhesively bound to the rotor hub, which is driven by an extended cran shaft. The rotor rotates within a wound stator assembly of which the laminated stator core is a part of the alternator's frame assembly, and thus, serves as a shield should a rotor magnet come loose.

Abstract: This  invention attaches to  a  sawmill carriage,  enabling an operator to turn a log carried by the sawmill carriage without having to return the sawmill carriage to a fixed location. The invention includes a  log turning hook with positioning guide bar that slides vertically with respect to, and pivots with,  a cylinder.  As the  turning hook with positioning guide bar  is lifting the log, the weight of the log is forcing the hook with positioning guide bar to pivot,  which rotates the log ninety degrees into position for the next saw cut.

Patent CA-2244019-A1 (CA)
Title: Viscous material dispenser and method for dispensing
Inventor: TOPPER ROBERT T
IPC: A23G9/28
Filed: 1994-11-23
Abstract: A reciprocating piston with an integral valve moves in a first direction within a cylinder to pressurize viscous material contained therein, such as ice cream or the like, thereby pushing it out of a dispensing nozzle located at one end of the cylinder while simultaneously extracting viscous material from a collapsible container into the other end of the cylinder by suctioning the material from the container.  When the piston moves in a second direction, the integral valve opens to allow the piston to pass through the previously suctioned viscous material then within the cylinder.  The dispensing nozzle includes a normally closed, spring-biased valve opened by the force of the pressurized material, closing of the valve being assisted by a transient suction force occurring as the valved piston begins to move in the second direction through the material.  Suctioning the material from the collapsible container, as opposed to compressing the container to expel the material, is preferable when the material contains entrapped gas, as is the case with ice cream, since repeated compression of such containerized material can diminish its quality.

Title: System and method for a multiresolution transform of digital image information
Inventor: BONNEAU ROBERT J
IPC: G06T9/00
Filed: 1997-04-03
Abstract: Digital image data is compressed by a technique combining the advantages of both wavelet and fractal encoding. The technique produces an encoded image which can be efficiently matched to other compressed images in order to identify the image being processed. The encoding technique spatially decimates the images (201) at numerous frequency scales produced by wavelet transformations and forms blocks comprising of groups of pixels at each frequency scale (270, 272, 274). The average modulus and angle values of the data in each block are compared to the next higher scale (109). Each frequency scale is then encoded for the blocks which have corresponding matching blocks in the adjacent scale (111). The technique provides the edge retention benefits of wavelet and the compression benefits of fractal encoding and also accelerates the matching process between the scales. A decoding technique which includes a synthetic edge procedure is used to reconstruct the image.

Patent CA-2261525-A1 (CA)
Inventor: TESSIER LYNN P
IPC: E21B23/04
Filed: 1999-02-12
Abstract: Apparatus is provided for stabilizing a PC pump suspended from production tubing. The stabilizing apparatus is connected to the pump and comprises a tubular body having a cylindrical wall, a longitudinal bore contiguous with the production tubing and three or more circumferentially-spaced linkages are disposed in longitudinal slots formed in the exterior of the tubular body. Each linkage comprises at least a passive and an active link pivotally connected end-to-end in series, the passive link being pivoted from the body. An annulus is formed within the cylindrical wall and contains a longitudinally movable annular piston pivotally connected to the active link.      The annulus is connected to the bore so that the piston is pressurized dynamically with fluid from the bore. Fluid pressure drives the piston, actuating the active link, thereby causing the linkage to expand radially outwards, the radial force being proportional with the fluid pressure. Under production pressures, a very high stabilizing force is produced. Accordingly, at non-flowing conditions, the pressure diminishes and the linkages are only spring-loaded, permitting movement of the pump and tubing while maintaining tool and apparatus centralization.

Inventor: MICHAELS GREGORY A
IPC: B01D53/04
Filed: 1998-06-05
Abstract: An acoustic oxygen sensor can be used in the output lines leading from the sieve beds. This sensor can communicate with a microprocessor to control the production and evacuation cycles of the sieve beds, i.e., for example to determine the period for which a bed is supplied with compressed air and communicates with the reservoir and to determine the pressure of the compressed air and to determine the amount of time that the product gas is fed through the flow equalization path to supply an aliquot of purging gas to a used bed. In the feedback loop, the microprocessor utilizes the measured oxygen concentration and flow rate to optimize the settings necessary to achieve maximum oxygen concentration and flow rate efficiency. Since the microprocessor has the ability to make incremental changes and compare relative values, the optimum values can be determined empirically eliminating the need to perform complex theoretical calculations.

Abstract: An inexpensive, PCMCIA-based radio transceiver is provided that interfaces to a separate baseband modem, which may itself be PCMCIA-based or may be an internal modem of a notebook computer. Together, the PCMCIA-based radio transceiver and the baseband modem realize a wireless modem. In order to minimize cost and increase versatility of the resulting wireless modem, the radio transceiver is a relatively unintelligent, protocol-agnostic, slave device that is controlled by commands issued by the baseband modem. The baseband modem may be a hardware modem or a software modem. In either case, the character of the baseband modem may be changed by downloading new software. The radio transceiver may also be exchanged for another within a family of radio transceivers, each of which customized for a particular radio standard. The result is an extremely flexible, extremely low-cost wireless modem solution.
