Abstract: A hydraulic actuator has a housing, a piston drive chamber in the housing, a fluid inlet into the chamber, and a piston reciprocable in the drive chamber. The piston has diametrical steps exposed to fluid under pressure to cycle the piston. A sleeve spaced from and surrounds over a length of the piston to define a return chamber therebetween. The housing has first and second seats. The first seat and a first surface of the sleeve define an exhaust valve, which has an exhaust port, for the return chamber. The exhaust port is opened and closed by reciprocating the sleeve. The second seat and a second surface of the sleeve an inlet valve for the return chamber. Reciprocating the sleeve opens and closes the return chamber to the drive chamber. The housing also has a bore through which a portion of the sleeve reciprocates to close the exhaust valve and seal the drive chamber. The piston and the sleeve are configured so that they interact hydraulically during cycling to generate hydraulic pressure changes in the return chamber. This reciprocates the sleeve between the exhaust valve and the return chamber inlet valve to cycle the piston. The piston/sleeve configuration also hydraulically cushions the piston as it travels toward the exhaust valve.

Abstract: A percussion piston for use in a drilling apparatus includes a drill bit and at least three tubular parts which increase in diameter in a direction extending from the drill bit toward a rear end of the piston. The piston further includes flanges positioned between the tubular parts and a first corresponding delivery space at the rear end of the piston. At least two additional corresponding delivery spaces are positioned between the first corresponding delivery space and the drill bit. Channels allow the transport of pressurized hydraulic fluid to and from the first and additional corresponding delivery spaces such that an energy pulse produced by impact of the piston on the drill bit is almost completely absorbed by the drilled object.

Abstract: In a process according to the present invention pre-reduced lateritic ores containing iron and nickel are leached with an aqueous sulphuric acid leach liquor containing or into which is introduced in the presence of the ore a peroxidant selected from hydrogen peroxide and peroxymonosulphuric acid. By so doing, the liquor is obtained with a lower concentration of iron than if the peroxidant had not been employed.In preferred embodiments the leaching is carried out at from 40.degree. to 70.degree. C. for a period of 1 to 5 hours; when hydrogen peroxide is used, it is preferably introduced continuously or progressively throughout the reaction period and when peroxymonosulphuric acid is used it is preferably introduced initially. The acidity of the liquor can be reduced at the end of the reaction to pH3 to 4 to further lower the content of iron in solution.

Abstract: The invention relates to a hydraulically operated impact device, such as a percussion hammer or some other breaking apparatus, comprising a control valve (6) for controlling pressure fluid supplied to and from the percussion piston (1) so that the direction of motion of the piston (1) can be changed in accordance with the cycle of operation of the impact device. According to the inventive idea, when the control valve (6) is in the impact position, the impact device is provided with a closed space that is partly bordered by the control valve and the percussion piston. The percussion piston (1) comprises a section which communicates with said space and which has a larger diameter than the upper end of the piston. The control valve and the percussion piston are thus able to move in the same direction until a connection is opened from this closed space to the upper end of the percussion piston (1).

Abstract: Coal is extracted in a longwall working with two subsidiary galleries disposed respectively at the ends of the longwall coal-face. The coal is obtained at the longwall face, is loaded and removed with the aid of a continuous conveyor acting as a longwall-heading conveyor which delivers into one of the subsidiary galleries. In order to extract the coal a plurality of long drill-holes, respectively spaced from the coal-face and from each other by a spacing which corresponds to the effective force of an explosive charge provided with a fuse-cord, are bored in the coal starting from one of the subsidiary galleries. Each of the drill-holes extends the full effective length of the coal face and is loaded with such an explosive charge, and then filled with water under pressure. The charges are exploded in succession, starting with the drill-hole adjacent the coal-face, whereupon the coal so acquired is loaded and removed by the continuous conveyor. The conveyor is operative at all points along the coal-face simultaneously, and is a worm conveyor with a worm associated with a channel open along its length to the coal-face.
