Patent CA-2556381-A1 (CA)
Inventor: SCHWEMBERGER RICHARD F
IPC: A61B17/072
Filed: 2006-08-17
Abstract: A linear surgical stapler adapted for applying a plurality of surgical fasteners to body tissue includes an anvil structure and a cartridge housing containing a plurality of surgical fasteners and a knife. The cartridge housing and anvil structure are relatively movable between a first spaced apart position and a second position in close approximation with one another. A firing mechanism is associated with the cartridge housing for ejecting the surgical fasteners from the cartridge housing to be driven against the anvil structure. The firing mechanism includes a slide bar at its distal end adjacent the cartridge housing. A lockout mechanism interacts with the cartridge housing for selective activation and deactivation. The lockout mechanism includes a lock tab that interferes with the slide bar of the firing mechanism moving the slide bar rotationally such that tabs on the slide bar move out of alignment with tabs on the knife during firing of the linear surgical stapler to prevent subsequent firing of the linear surgical stapler.

Abstract: A method of detecting leaks in the filter bags (106) of a baghouse filter chamber (101) that includes determining when the filter bags (106) have been cleaned and, during a post-cleaning period after the cleaning of the filter bags (106), determining whether the opacity level of the exhaust of the baghouse filter chamber (101) exceeds a predefined opacity limit. The determining whether the opacity level of the exhaust of the baghouse filter chamber (101) exceeds a predefined opacity limit may include monitoring the opacity level of the exhaust of the baghouse filter chamber (101) with an opacity sensor (112) during the post-cleaning period and comparing the opacity readings during the post-cleaning period with the value of the predefined opacity limit.
Patent CA-2562274-A1 (CA)
Inventor: CARTER NICK
IPC: B29C48/05
Filed: 2005-04-12
Abstract: The electro-conductive substrate of the present invention may comprise filaments extruded from a die orifice and at least one metal powder dispensed from a second orifice of the same die unit by way of a gas or liquid carrier.  As the polymeric filament is extruded from the die, one or more metal powders may be simultaneously dispensed to coat the surface of the filament. As the polymeric melt and metal powder is extruded, air pressure is impinged upon the metal powder directing the powder toward the extruded filament. The metal powder adheres to the molten polymer as it is extruded for the die, coating the surface of the filament. The metal power may also be incorporated into the polymeric melt prior to extrusion.

Title: Variable focal length lens
Inventor: BAEK SANG HYUNE
IPC: G02B26/00
Filed: 2005-05-27
Abstract: A micromirror array lens consists of many micromirrors (13) with two degrees of freedom rotation and one degree of freedom translation and actuating components. The array of micromirrors makes all lights scattered from one point of an object have the same periodic phase and converge at one point of image plane. The actuating components control the positions of micromirrors electrostatically and/or electromagnetically. The optical efficiency of the micromirror array lens is increased by locating a mechanical structure upholding micromirrors and the actuating components under micromirrors.  Semiconductor microelectronics technologies can remove the loss in effective reflective area due to electrode pads and wires. The lens can correct aberration by controlling each micromirror independently. Independent control of each micromirror is possible by known semiconductor microelectronics technologies. The micromirror array can also form a lens with desired arbitrary shape and/or size.
Patent CA-2571147-A1 (CA)
Inventor: ANTHONY MICHAEL P
IPC: H03M1/12
Filed: 2005-06-03
Abstract: A pipelined analog-to-digital converter in which signal value samples are represented differentially by pairs of charges and which uses charge-coupled-devices (CCDs) for delay and arithmetic operations on the charges is presented. In the pipeline, each successive stage resolves an equal or smaller charge difference. After a certain number of pipeline stages, the common-mode component of the signal-charge pair is reduced. The pipeline stages following this common-mode-charge reduction stage have a reduced charge capacity and size, allowing more sensitive charge comparison. The result is improved A/D  converter resolution and reduced power consumption.

Title: Preparation for use of aspartate and vitamin b12 or biotin for regulating ketone bodies
Inventor: HAGEMAN ROBERT JOHAN JOSEPH
IPC: A23L13/60
Filed: 2005-07-18
Abstract: It has been found that high amounts of aspartate equivalents in combination with vitamin B12 and/or biotin, especially in relative absence of glutamate equivalents, improve the metabolism of ketobodies and/or lactate in a mammal's body, especially in diseased or traumatic conditions. As a result, levels of ketobodies and lactate can be decreased and unphysicologically high acidity normalised. Thus, it is an object of the invention to provide an enteral nutritional or a pharmaceutical composition for the treatment and/or prevention of disturbed ketone and lactate metabolism, i.e. elevated concentrations of ketone bodies, lactate and/or other organic acids and/or insufficient pH homeostasis, especially elevated concentrations of ketone bodies and/or lactate, in a mammal's blood, wherein the composition comprises high amounts of aspartate equivalents in combination with vitamin B12 and/or biotin, preferably in relative absence of glutamate equivalents.

Title: Supercritical fluid-assisted deposition of materials on semiconductor substrates
Inventor: KORZENSKI MICHAEL B
IPC: C23C30/00
Filed: 2004-07-28
Abstract: Supercritical fluid-assisted deposition of materials on substrates, such as semiconductor substrates for integrated circuit device manufacture. The deposition is effected using a supercritical fluid-based composition containing the precursor(s) of the material to be deposited on the substrate surface. Such approach permits use of precursors that otherwise would be wholly unsuitable for deposition applications, as lacking requisite volatility and transport characteristics for vapor phase deposition processes.

Title: Method and installation for the production of secondary steel based on scrap
Inventor: MEYN MATTHIAS
IPC: C21C5/56
Filed: 2005-12-02
Abstract: The invention relates to the production of secondary steel based on scrap.  According to the invention, the scrap (10) is fed into a scrap preheater (2) via a charging device (1), is preheated therein, is then transferred into a melting unit (3), and is fused exclusively with the aid of primary energy. The invention is characterized in that the process gases (19) that are discharged from the melting unit (3) are used indirectly by heating a gaseous preheating medium, e.g. air (18) or inert gas, rather than being used for directly preheating the scrap (10), thus making it possible to energetically, fluidically, and spatially disconnect the preheating and melting process as well as the post-combustion and preheating process.
