Abstract: L'invention concerne un procédé relatif à l'extraction de sulfure d'hydrogène et d'ammoniaque dans un gaz (12), du type gaz de colonne de désulfuration à la vapeur. Le gaz qui contient les deux substances considérées est injecté dans un premier réacteur (38) où seule une partie de ces substances est sorbée dans une solution de nettoyage à base de sulfite d'ammonium et d'hydrogénosulfite d'ammonium (40). Les substances sorbées réagissent avec les sulfites de la solution pour donner du thiosulfate d'ammonium. Les résidus non sorbés des substances en question sont injectés dans un épurateur à eau (74): l'eau, l'ammoniaque et le sulfure d'hydrogène y réagissent pour donner de l'hydrogénosulfite d'ammonium et un gaz renfermant du sulfure d'hydrogène résiduel n'ayant pas réagi (78), lequel peut être transformé en dioxyde de soufre par combustion. Ce dioxyde de soufre (ou le dioxyde de soufre provenant d'une autre origine) (84) est mélangé avec la solution de nettoyage (58) dans un second réacteur (82) où il réagit avec l'ammoniaque pour donner le sulfite d'ammonium et l'hydrogénosulfite d'ammonium nécessaires à l'élaboration de thiosulfate d'ammonium.
Patent CA-2446691-A1 (CA)
Inventor: SENDELBACH LEE ANTON
IPC: G06F13/10
Filed: 2002-05-31
Abstract: A method and system for transmitting and receiving data from a host computer system to an Ethernet adapter are provided. The method comprises establishing a connection between the host system and the Ethernet adapter pushing a transmit or receive request message from a host system device driver to the Ethernet adapter's request queue. Access to host memory is transferred to the Ethernet adapter. If data is being transmitted to the Ethernet adapter, the adapter reads the data from a location in host memory specified in the transmit request message, and then transmits the data onto transmission media (e.g. wire, fiber). If the request message is a receive request, the adapter reads the data from the media and then sends the data into host memory at the location specified in the receive request message. When the data transfer is complete, the adapter sends a response message back to the host. The response message includes a transaction ID which is used by the host device driver to associate the response message to the original request message.

Title: Down-stroke dispenser
Inventor: SEDLAR NANCY J
IPC: E03D9/02
Filed: 2002-05-10
Abstract: A dispenser is provided for dispensing cleaning chemicals such as toilet bowl cleaners. It has a dosing chamber containing therein a floating shuttle that seals a lower opening in the dosing chamber and floats up there from as an aliquot of chemical is prepared for release during the next cycle. There is also a float controlled external valve pin at a lower end of the dispenser for alternately opening and closing a lower opening in the dosing chamber. The level of water in the tank controls the movement of the valve pin, and dispensing of the cleaner chemical controls movement of the floating shuttle.  A grommet provides a valve seat for both the floating shuttle and valve pin.

Title: Longitudinally flexible stent
Inventor: RICHTER JACOB
IPC: A61F2/915
Filed: 2002-09-06
Abstract: An intravascular stent (fig. 10) especially suited for implanting in curved arterial portions. The stent (fig. 10) is formed of intertwined meander patterns forming triangular cells (804). The triangular cells (804) are adapted to provide radial support, and longitudinal flexibility after expansion. The triangular cells (804) provide increased coverage of a vessel wall. The stent (fig. 10) can have different portions adapted to optimize radial support or to optimize longitudinal flexibility. The stent (fig. 10) is curved and cells on the outside of the curve open in length, but narrow in width whereas cells on the inside of the curve shorten in length but thicken in width to maintain a density of stent element area which much more constan t than otherwise between the inside and the outside of the curve. As a result, when the stent is coated with a medicine the more constant density of stent elements results in an even dose being applied to the inside wall of the lumen, avoiding the possibility that a toxic dose be supplied at one area while a less than effective dose is applied to another area.

Title: Fuel cell fluid flow field plates
Inventor: HOOD PETER DAVID
IPC: H01M8/02
Filed: 2002-10-03
Abstract: A bipolar fluid flow flied plate for a fuel cell delivers fuel to a porous anode electrode and oxidant to an adjacent porous cathode electrode. The flow field plate comprises an electrically conductive, non-porous sheet into which fluid flow conduits are formed. A first fluid flow channel is patterned into a first face of the sheet and a second fluid flow channel patterned into the opposite face of the sheet. The pattern of the first channel comprises an interdigitated comb that co-operates with a pattern of the second channel comprising a continous serpentine path, so that no portion of the first channel directly overlies the pattern of the second channel over a substantial active area of the sheet. This allows the channels to be formed with combined depths that exceed the total plate thickness, thereby increasing fluid flow volumes.

Abstract: A method of controlling the dump position of a dragline (1) of the type where inclination of the bucket (4) is controlled by differential control of the front hoist rope (7) and the rear hoist rope (8), in order to control dumping too close to the dragline house (2) in a position where the bucket will not release all the load and where slackness in the front hoist rope can cause fouling and serious damage. The complex locus of rear hitch positions (14) that will result in an acceptable dump angle at the bucket when dumped, is empirically transposed to a locus of rear hitch positions (15) at a typical carry angle before dumping, which is in turn approximated by a vertical cylindrical envelope (16). Calculation of when the rear hitch position (13) reaches the envelope (16) may be easily performed by a computer in real time using available parameters such as rear rope inclination and payout values.

IPC: B21G1/00
Filed: 2004-08-16
Abstract: A method for manufacturing a surgical needle devoid of a grinding process includes the steps of swaging a needle blank to define a substantially tapered or conical needle end, pressing the tapered needle to form a plurality of intersecting surfaces and forming cutting edges along the lines of intersection of the intersecting sides. The needle may be subjected to an etching process (e.g., an acid bath) to sharpen the cutting edges and/or provide a matte finish on the needle. The needle produced by the novel process is extremely sharp and durable, and exhibits an enhanced retention of sharpness relative to conventional ground needles over periods of prolonged use.
