摘要： A coal extract hydrocracking catalyst having particular utility in a two stage coal extracting process which has a first liquid hydrogen donor solvent oil extraction stage and a second stage comprising catalytic hydrocracking of the extract. Desired levels of hydrocracking and hydrogenation of the extract, with an acceptable level of naphthene formation, are achieved by using on the coal extract hydrocracking catalyst a mixture of a promoted W or Mo catalyst with an unpromoted W or Mo catalyst.

摘要： The trailing drum of a double-ended ranging drum shearer is steered in a seam by producing an algorithm which determines, as a result of information derived from signals from the machine dependant on its tilt, direction and amount of movement along a face being cut. The height of the leading drum is used as a reference from which to determine the optimum position of the trailing drum in order that a constant quality of desired mined material is obtained.

摘要： A directional antenna for an electromagnetic sensing system comprises a generally cylindrical tube of electrically-conductive material a portion of the tube being cut away to define a transversally-facing window. The non-cut away portion of the tube provides a backing shield for a pair of antenna elements mounted on a generally `V`-shaped support. A cover of dielectric material is arranged over the antenna elements.

摘要： A leaky-feeder or other form of guided radiocommunication system serving a linear route or track is equipped at intervals with static marker devices which successively modify a radio signal passing those points between a fixed base station and a personal or mobile station travelling the route. By reference to the resulting overall modification to the signal as received at the mobile or fixed station the position of the mobile station may be determined or delimited.

摘要： A combustor for burning a feedstock includes a cylindrical body having a tangential feedstock inlet and an exhaust outlet. A catchment chamber of hollow cylindrical form intersects the wall of the body and opens into the cavity to provide a common boundary. Swirling or vortical flow is created in the cavity and a secondary vortex is generated and driven within the chamber by the main flow. In operation contaminant matter is sheared off from the flow in the body into the chamber and is entrapped by the secondary vortex from which it is precipitated, there being no net gas flow across the boundary.

摘要： The present invention relates to a process for hydrocracking SGE of carbonaceous material to produce light distillate, including chemical feedstocks and transport fuels.A mixture of crushed coal and a solvent is fed to an extractor 1 wherein the solvent is heated and pressurized to form a supercritical gas. Carbonaceous material is extracted from the coal into the gas. The unextracted coal, including ash and some carbonaceous material, is separated from the SGE in solution in the supercritical solvent in a separation stage 2. The SGE in the solvent is maintained in the supercritical state and fed to a hydrocracking stage 3 wherein it is mixed with excess hydrogen. After hydrocracking, the SGE in supercritical solution is passed through a pressure let-down valve 4 to a distillation stage 5 wherein the product of the hydrocracking stage 3 is separated into gases, solvent for recycling, light distillate and material boiling above 350.degree. C. The light distillate may be further treated to produce transport fuels.
