    摘要： A process for demineralizing coal includes the steps of forming a slurry of coal particles in an alkali solution, the slurry containing 10-30% by weight coal, maintaining the slurry at a temperature of 150-250° C. under a pressure sufficient to prevent boiling, separating the slurry into an alkalized coal and a spent alkali leachant, forming an acidified slurry of the alkalized coal, the acidified slurry having a pH of 0.5-1.5, separating the acidified slurry into a coal-containing fraction and a substantially liquid fraction, subjecting the coal-containing fraction to a washing step, particularly a hydrothermal washing step, in which the coal-containing fraction is mixed with water and a polar organic solvent or water and an organic acid to form a mixture and separating the coal from the mixture. The demineralized coal has an ash content of from 0.01-0.2% by weight and can be used a feed to a gas turbine.

    摘要： A wire feeder including a motor driving a set of feed rolls to force a welding wire from a spool through a welding torch to a welding operation. The wire feeder has an input lead to be connected to the output terminal of a remotely located power source having an on condition and an off condition where a welding current is directed to the output terminal only when the source is in the on condition. A weld starting trigger with a weld start position located adjacent the torch closes a switch when the trigger is shifted to the weld position, a circuit senses when the switch is closed, and a transmitter on the wire feeder transmits a start signal to the power source when the trigger switch is closed whereby the power source is shifted to its on condition when the trigger is in the weld position.

    摘要： A method and apparatus for providing an access door within a sectional garage door. The access door allows access to the interior of a building through the sectional garage door without having to open the sectional garage door. The access door is capable of opening by pivoting about a substantially horizontal axis when the sectional garage door is closed. Further, the access door is adapted to pivot with the sectional garage door as the sectional garage door moves to and from the closed position to the open position.

    摘要： A process and system is provided for briquetting particulate matter such as moisture-containing bituminous and sub-bituminous coal. This process includes partially drying the particulate matter and feeding, the partially dried particulate matter to a briquetting apparatus under conditions such that water vapour is released from the particulate matter during feeding. The particulate matter is passed through briquette forming rollers to form briquettes. The released water vapour substantially displaces or prevents the ingress of a large proportion of other gaseous components from the atmosphere surrounding an/or intermixed with the particulate matter. The particulate matter that is fed to the briquetting apparatus is surrounded by and intermixed with a gaseous component containing 70 to 100% by volume of water vapour at the point where it enters the briquette-forming part of the briquetting apparatus, such that when the particulate matter is compressed during briquette formation, the water vapour liquefies and the pressure buildup of gaseous material in the thus-formed briquettes is minimised. This reduction in the pressure buildup of gaseous components also acts to reduce blow-back of gases as the coal fines are being formed into briquettes.
