Patent CA-2482340-C (CA)
Inventor: CASCONE PAUL J
IPC: A61K6/04
Filed: 2004-09-21
Granted: 2009-12-15
Abstract: Dental prostheses are machined from a metallic body instead of being made by lost wax casting. Suitable gold base alloys have only base metal alloying additions which are more readily oxidized than gold and when combined with the gold can be age hardened. Exemplary metals include titanium, zirconium, yttrium and chromium. Scrap from the machining of a dental prosthesis is melted in air so that the base metals are all oxidized and substantially pure gold is reclaimed for reuse in new alloys.

Patent CA-2488296-C (CA)
Title: Urine collection apparatus
Inventor: VERMAAK JAN CHRISTIAAN
IPC: A61G9/00
Filed: 2004-11-23
Granted: 2012-04-17
Abstract: Urine collection apparatus is provided which can be used to assist bedridden and/or incontinent patients, particularly female patients. The apparatus includes a urine collector which is shaped for location against the perineal region of a patient adjacent the urethra. The urine collector comprises a hollow body having opposed ends in which an inlet for air and an outlet for air and urine are formed, respectively. The body has a central region between the end regions with a reduced cross-sectional area. This effectively creates a venturi adjacent the patient's urethra when air passes through the collector. The apparatus includes a urine receptacle with an inlet for receiving air and urine from the collector, and an outlet for air which is connectable to a source of low pressure. The source of low pressure will typically be an impeller driven by an electric motor, which creates a sufficiently strong air flow through the apparatus to entrain urine and transport it to the receptacle.

Abstract: A handheld electronic device includes a reduced QWERTY keyboard and is enabled with disambiguation software. The device provides output in the form of a default output and a number of variants. The output is based largely upon the frequency, i.e., the likelihood that a user intended a particular output, but various features of the device provide additional variants that are not based solely on frequency and rather are provided by various logic structures resident on the device. The device enables editing during text entry and also provides a learning function that allows the disambiguation function to adapt to provide a customized experience for the user. The disambiguation function can be selectively disabled and an alternate keystroke interpretation system provided. Additionally, the device can facilitate the selection of variants by displaying a graphic of a special <NEXT> key of the keypad that enables a user to progressively select variants generally without changing the position of the user's hands on the device.

Title: Gfci receptacle having blocking means
Inventor: GERMAIN FRANTZ
IPC: H01H83/04
Filed: 2004-01-30
Granted: 2011-12-20
Abstract: Located within a GFCI device (10) having receptacle openings (20, 21) in its face (16) is a movable contact bearing arm (50) held in either a closed or open position by a latching member (100) connected to a spring loaded reset button (30). The reset button (30) assumes a first depressed position when the GFCI (10) is in a conducting state, and a second extended position when the GFCI (10) is in a non conducting state. A blocking member (300) located within the body of the GFCI (10) is adapted to be moved to a first position to blocks at least one opening of each receptacle (20, 21), or to a second position to allow the prongs of a plug to enter the receptacle openings (20, 21). When the GFCI (10) is in the conducting state, the reset button (30) is in its first position and holds the blocking member (300) in its first position to permit the prongs of a plug to be inserted into the receptacle openings (20, 21).  When the GFCI (10) is in a non-conducting state or is defective, the reset button (30) and the blocking member (300) are in their second positions and the prongs of a plug are prevented from entering the receptacles (20, 21).

Abstract: A novel and improved method and apparatus provide for controlling an operation of an access terminal while processing a signal from an access point in a communication system. Various aspects of the invention provide for an access terminal to disable a handoff process when its demodulator or decoder is operating to demodulate or decode a control message received from an access point. The operation of the access terminal is controlled in a manner that prevents terminating prematurely the demodulation and decoding process of a control signal by a handoff process. As a result, the access terminal may continue operating in a normal wake up/ sleep cycle period while conserving its battery power.

Granted: 2012-04-24
Abstract: A method and a system to provide allocation of mixed flows back to individual sources in an oil and/or gas production system. The method is independent of sub sea on-line measurements. Instead the method uses comparably inexpensive topside equipment for compositional allocation of the flows. The method comprises the use of an on-line allocation algorithm. The method is suitable where improved reliability of flow allocation back to wells and reservoirs is needed. The allocated flow may be used to calculate and estimate the remaining volumes in a reservoir.

Title: Improved elevated rail transportation system

IPC: B61B13/10
Filed: 2004-06-04
Granted: 2012-01-10
Abstract: A system for propelling a vehicle along an elevated, pneumatic power tube carried by exterior support structure above ground. First and second angles define tracks for the vehicle and extend parallel to the power tube.  Undercarriages secured to the vehicle including vehicle support and guidance wheels which are rotatable about axes inclined relative to legs of the angle tracks have a periphery that engages the legs of the angle tracks so that the weight of the vehicle is supported by the tracks and the support structure only. A pneumatic propulsion unit is movably disposed inside the power tube and is guided along rails on the inside of the power tube. A magnetic coupler having first and second cooperating magnetic elements is attached to the vehicle and the propulsion unit in operative alignment with each other. A  portion of the power tube located between the magnetic elements is constructed of a non-magnetic and non-conductive material and extends over the length of the power tube. The propulsion unit has a thrust carriage with a thrust valve that forms a collapsible, frusto-conically shaped wall formed by a multiplicity of overlapping, angularly inclined blades that are concentrically disposed in the power tube. An actuator is coupled to the blades for selectively increasing an angle of the blades until free ends thereof contact an interior surface of the power tube, to thereby prevent the flow of air through the tube past the wall, and for retracting the blades so that the free ends thereof are spaced apart from the interior surface of the power tube, the valve generating a force acting in the longitudinal direction of the power tube when the free ends of the valve blades engage the interior surface.

Abstract: Disclosed is an anode material comprising a metal or metalloid core layer capable of repetitive lithium intercalation/deintercalation; an amorphous carbon layer coated on the surface of the metal or metalloid core layer;  and a crystalline carbon layer coated on the amorphous carbon layer. The anode material not only maintains a high charge/discharge capacity, which is an advantage of a metal or metalloid-based anode material, but also inhibits changes in the volume of a metal or metalloid core layer caused by repetitive lithium intercalation/deintercalation in virtue of an amorphous carbon layer and a crystalline carbon layer, thereby improving the cycle life characteristics of cells.
