A mobile water station is mounted in the service tunnel and is connected to the mid-carrier which conveys the water to the mining machine at the end which is effective.

Abstract: A device for multiplying the effective pulsations on a column of liquid which operates an underground pump. The pulsations are created by a pulse generator at the ground surface and are transmitted through the column of liquid being pumped to operate the underground pump. The pulse multiplier is interposed in the single tube at the ground surface and is effective to partially divert the flow of liquid from the tube to a receiving tank when gas pockets in the column of liquid reach a predetermined degree and relieve the column of the gas pockets by by-passing the liquid under pulsations from the pulse generator back to the receiving tank.

Abstract: A method of strip mining in which a plurality of vertical shafts of square cross section are formed closely adjacent to one another with each shaft extending through overburden and a layer of valuable material such as coal. As spoil is removed in forming one shaft it is conveyed to a previously formed shaft and deposited therein. The apparatus includes a casing of square cross section, a cylindrical auger casing within the square casing, an auger rotatable in the auger casing and a square cutter at the lower end of the square casing. The latter is slidably mounted on a vertical track and is power driven vertically to force the cutter into the earth formation being worked. The auger is rotated under power to cut into the earth formation and remove spoil and coal therefrom. The upper end portions of both casings are formed with two sets of aligned discharge ports. A movable closure is provided for each set and a rake for each set.

Abstract: A ball mill including the usual drum and a trommel screen rotatable therewith together with mechanism for returning damaged balls and large pieces of aggregate directly from the trommel screen to the drum. This mechanism comprises a plurality of blades mounted on the inner surface of the cylindrical screen which pick up material in the trommel screen as an incident to rotation thereof and dump it onto a trough which extends from the screen to the drum. A jet of water is introduced into the trough at its outer end and passes the materials back into the drum.

Abstract: A portable roof winch comprising a collapsible frame that is adjustable to accommodate the slant of a roof, an extensible beam consisting of two telescoping parts one of which is pivotally mounted on the frame on a vertical axis and the other part being moveable with respect to the pivot and having a manually operable winch mounted thereon at a location adjacent to and spaced from the free end of the moveable part, together with a seat for an operator on the moveable part beyond the winch. A cable is taken up on the winch, extends along the beam and is passed over a pulley at the free end of the fixed beam part. A load engaging hook is attached to the end of this cable.

Abstract: An internal combustion engine in which heat is derived from the engine cooling system and/or the exhaust to heat a working fluid in a closed circulatory system. This heat transforms the working fluid into a gas which is delivered to a turbine which drives a generator. The generator delivers DC current to an electrolysis cell in which water is decomposed. The water is decomposed by the electric current into its oxygen and hydrogen components. The oxygen is passed to the air intake of the engine carburetors, while the hydrogen is conveyed to a carburetor therefor. Also included is a carburetor for conventional hydrocarbon fuels. The two carburetors are connected by linkage which may be operated either manually or by pressure to vary the ratio of the carbureted fuels which are delivered to the engine.
