Patent CA-2624670-A1 (CA)
Inventor: ERRINGTON WILLIAM JOHN
IPC: C22B5/10
Filed: 2006-10-05
Abstract: A method for producing lead involves feeding lead concentrate, flux and solid fuel passing to a feed preparation unit (10). The prepared, mixed feed is then passed to a lead smelting furnace (14), such as an ISASMELT furnace or other top entry, submerged lance furnace. Air or oxygen (16), is injected into the molten charge in the ISASMELT furnace (14) via the submerged lance. In furnace (14), the feed mixture is converted into lead bullion and a lead-containing slag. The lead bullion is removed via a taphole or weir (18). The slag is removed via a taphole or weir (20). The slag (20) removed from the furnace (14) is formed into lumps having a desirable size range. The slag lumps (20), together with coke and flux (26) are fed into a blast furnace (28). In the blast furnace (28), the slag is converted into lead bullion that is removed via a taphole or weir (30) and discard slag that is removed via a taphole (32). The lead bullion removed at (18 and 30) may be subsequently fed to a lead refinery (34) for further treatment.

IPC: H04B1/707

Abstract: A method and a telecommunications device for selecting a number of code channels and an associated spreading factor for a CDMA transmission is proposed. According to the invention a set of permissible parameter pairs with the parameters being a number of code channels and an associated spreading factor is determined according to at least one first selection criterion. Then a parameter pair from the set of permissible parameter pairs for the CDMA transmission is selected according to at least one second selection criterion. In this selection process, the spreading factor is used as a second selection criterion with a higher value being preferred over a lower value if both spreading factors are below or equal to a threshold spreading factor value. The invention accounts for the fact that in a certain regime low spreading factors involve a prohibitively high processing load and lead to increases inter symbol interference.
Patent CA-2633616-A1 (CA)
Inventor: CALLEY DAVID
IPC: H02P9/04
Filed: 2006-07-17
Abstract: Control features for a wind turbine that control the turbine over a range of wind speeds and under triggering conditions with reduced noise, cost, and reliability issues associated with other such controls. Control is accomplished via control electronics, which adjust the torque produced by the electrical output generation device (e.g., alternator) within the wind turbine.  During normal operation, torque is adjusted for optimum aerodynamic performance and maximum output of power. In winds above rated power, the control circuit regulates torque to lower aerodynamic performance, as necessary to maintain desired power level output. In triggering conditions, such as during simultaneous control circuit failure and loss of some portion of the electrical output generation device in extreme winds, wind turbine control is accomplished by increasing torque (e.g., via a separate controller) from the electrical output generation device via shorting of windings, so as to cause retardation of blade rotation.

IPC: G01M13/023
Filed: 2007-03-28
Abstract: An apparatus and method with the capability to monitor endless belts and related belt drive systems by non-contact sensors for wear or an anomalous function, determining the state of belt drive system and detecting early stages of belt and system failure. A sensing unit featuring one or several independent sensor elements is placed adjacent to or in proximity of the belt, thereby monitoring several simultaneously occurring normal modes of operation of the belt. The sensor can determine soundness of the whole timing drive continuously by processing the collected signal and detecting structural damage. The collected data is processed by a microcontroller integrated with the sensor. The apparatus and method for monitoring endless belts for wear or anomalous function uses a non- contacting capacitor array comprised of one or several sensing elements placed adjacent to or in proximity of the belt and connected to electronic circuitry that is particularly adapted to sense the dynamic capacitance change coupled with electrocapacitive and piezoelectric effects exhibited by the belt. The apparatus is further capable of monitoring drive components related to the belt by detecting if the belt is affected by the anomalous function of the related components. The sensor continuously monitors the belt during normal operation of the belt drive. The sensor is particularly adapted to sense the belts currently used in workshop, industrial and automotive applications and feature a polymer matrix with a fiber cord load bearing core.

Title: Modified vird2 protein and its use in improved gene transfer
Inventor: REAVY BRIAN
IPC: C12N15/82
Filed: 2007-05-10
Abstract: There is provided a method for Agrobacterium-mediated gene transformation of a host cell. The method uses an Agrobacterium which expresses a VirD2 protein resistant to cleavage by a caspase. The VirD2 protein is modified by replacement of an aspartic acid residue with an alternative amino acid at one or more of the caspase cleavage sites within the protein amino acid sequence. This method improves the low efficiency of Agrobacterium-mediated gene transfer in certain plant cells and in animal cells caused by caspase cleavage of the VirD2 protein. The modified VirD2 protein, a gene for its expression and a method of producing a protein of interest by Agrobacterium-mediated transformation of a host cell are also described.
