摘要： A process and reactor for removing impurities from a carbon material, involving providing a carbon feed into the electrothermal reactor; providing a gas into the reactor; passing the carbon feed through the reactor in a direction; heating the carbon feed using one or more electrodes; volatizing non-carbon material of the feed with the heat; and discharging the purified carbon material at the second location. So purified, the carbon material may be battery-grade. The feed may be passed through the reactor in a generally horizontal direction. The velocity of the feed in the reactor may be controlled to achieve a select resident time sufficient to volatize a desired amount of impurity. The process and reactor may be configured to inhibit back-mixing of the feed.

摘要： A treatment process for crystallizing a metal sulfate involving pre-treating a feedstock comprising calcium, magnesium, and/or lithium impurities, the pre-treating involving pre-leaching the feedstock in the presence of a lixiviant, selectively extracting a first portion of any of the impurities from the feedstock, and forming a leached solution comprising an uncrystallized metal sulfate and any remaining impurities; and/or refining the leached solution and removing a second portion of any of the remaining impurities; and crystallizing the uncrystallized metal sulfate from the leached solution to form a crystallized metal sulfate. So processed, the crystallized metal sulfate may be battery-grade or electroplating-grade.

摘要： A machine and method for making underground excavations in rock, The machine comprises hydraulic percussion hammers which drive drill bits into the rock face to be bored. A hydraulic power unit (HPU) is located on the machine. The HPU powers the hydraulic percussion hammers. The HPU and percussion hammers form a hydraulic power distribution circuit. The percussions hammers may be moved during operation. The method comprises providing a hydraulic pressure to drill bits using a hydraulic pressure means, pulsing the drill bits against the rock face using the hydraulic pressure to form an excavation, and advancing the hydraulic pressure means into the excavation.

摘要： A configuration of switches added to a line control circuit allows for switching back and forth between a configuration featuring a series-connected thyristor switch and reactor and a configuration featuring a parallel-connected thyristor switch and reactor. Connecting the reactor in series with the thyristor switch allows a controlled high-impedance circuit configuration that is particularly well adapted for cold furnace start-ups and furnace idling. In this manner, there is reduced need for such equipment as extra startup transformers, alternate low-voltage power supply configurations and temporary specialty electrical apparatus for cold furnace start-ups.

摘要： A method for determining a length parameter of an electrode during operation of an electric arc furnace. An internal duct extends through the length of the electrode and is open at its lower end. A waveguide having a solid core is received in the internal duct and comprises a material having a low dielectric constant and high temperature resistance. The solid core of the waveguide includes at least one target. An electromagnetic radiation signal is emitted from a source and transmitted through the waveguide and the signal is diffracted and/or reflected from at least one target to produce at least one return signal which is transmitted back through the waveguide. A time or frequency difference between the emitted signal and the return signal is measured and the length parameter is calculated based on this difference.
