20130041520 | METHOD AND SYSTEM FOR FACILITATING DESIGN OF A HIGH VOLTAGE (HVDC) CONTROL SYSTEM, AN HVDC SYSTEM AND A METHOD FOR OPTIMISING AN HVDC SYSTEM - THIS invention relates to a method of and a system for facilitating design of a classic High Voltage Direct Current (HVDC) control system, a method for optimising a classic High Voltage Direct Current (HVDC) control system, and a HVDC control system. In particular, the invention comprises the steps of determining at least a current control plant transfer function for a rectifier and/or inverter of the classic HVDC control system by using a time domain current equation; determining at least a voltage control plant transfer function for at least a rectifier of the classic HVDC control system by using a time domain voltage equation; using the determined current control plant transfer function for the rectifier and/or inverter, and/or the determined voltage control plant transfer function for at least the rectifier to facilitate design of the HVDC control system. | 02-14-2013 |
20100258660 | Method of Grinding a Mineral Containing Ore - A method of grinding a mineral-containing ore, which includes grinding the mineral-containing ore in a primary milling process and thereafter fine grinding the mineral-containing ore in a secondary ball-mill. A composite grinding medium comprising a mixture of steel balls and pebbles is used in the secondary ball-mill. The pebbles have an average size which is relatively smaller than the average size of the balls. The grinding medium includes an optimum mixture of approximately 25% pebbles and 75% steel balls by volume. The pebbles have a hardness which is substantially equivalent to or relatively harder than the hardness of the mineral-containing ore. The use of the composite grinding medium including the optimum mixture of steel balls and pebbles results in significant savings in energy consumption together with a reduction in ball consumption. | 10-14-2010 |
20100105932 | RECOVERY OF COMPONENTS MAKING UP A LIQUID MIXTURE - A process for recovering hexafluoropropylene and hexafluoropropylene oxide from a liquid mixture of these components is provided. The process includes, in a stripping stage, contacting the mixture with a gaseous stripping agent, thereby to strip hexafluoropropylene from the mixture. A gaseous product comprising hexafluoropropylene and gaseous stripping agent is withdrawn from the stripping stage, as is a liquid product comprising hexafluoropropylene oxide. | 04-29-2010 |
