A coal shaver which includes cutter fronts also includes shearing blades and bottom blades at both ends of the coal shaver, for extraction work in both shaver cutting directions; the coal shaver having shearing blades attached to the shaver body and bottom blades attached to the shanks, which are arranged to be adjustable and locked in guides at the shaver body. The coal shaver is designed such that the shearing blades are attached to the cutter strips, which are arranged to be pivoted at the shaver body around its longitudinal axis, and the bottom blades are attached to the shanks, arranged to pivot around the swivel bolt, which is attached across the mining direction, and is guided such that it is movable in the longitudinal direction in the coulisse guides at the shaver body.

A truck having a truck body with lift track and a battery electrically connected to the body and a platform for moving along the lift track. A box holding a hydraulic unit with solenoid valves for moving the platform is attached to the truck body. A movable wireless switch having an internal power source is on the platform. When a user operates a switch the movable wireless switch emits a movement signal from a movable antenna electrically connected to the truck body. A fixed wireless switch is on the truck body. When a user operates a switch the fixed wireless switch emits a movement signal from an antenna electrically connected to the body. A wireless receiver receives the movement signal and then applies control signals to the hydraulic unit. The wireless receiver also receives a sensor signal and emits an alert if the hydraulic unit has a problem.

The invention relates to a gate turn-off thyristor which includes, per unit cell, a cathode-side emitter strip and two anode-side spaced emitter strips which overlap in position with the edge of the cathode-side emitter strip. In such a GTO thyristor, the maximum disconnectable anode current greatly decreases during turn-off with increasing voltage rise rate, since the electrical fields developing in the non-regenerative transistor region centered underneath the cathode-side emitter strip are too high. Reduction of the field intensity occurring in the non-regenerative transistor region and thus reduction in the decrease of the maximum disconnectable anode current is realized, according to the invention, in that a p-type zone is disposed between the two anode-side emitter strips to dynamically limit the electrical field, with this p-type zone injecting holes to a lesser degree than the adjacent emitter strips and essentially only during turn-off of high currents.

A lubricating arrangement attached end face at the engine housing of a reciprocating piston engine is surrounded by an oil pump housing which is composed of two housing parts cast of magnesium. The oil pumps are preassemblable in the oil pump housing. The couplings of the oil pumps and the lubricating connections are so constructed that the oil pump housing is easily assemblable at the engine housing as a structural unit.

A method for variably adjusting a compression ratio of combustion chamber of an internal combustion engine employs a device of a piston associated with the combustion chamber. The device is coupled via respective coupling areas to a piston pin for connecting the piston to a connecting rod of the internal combustion engine. To adjust the compression ratio the piston pin, which is associated with the device, is rotated relative to the piston. The piston pin includes at least one eccentric element arranged eccentrically with regard to the coupling area of the piston pin for connecting the piston pin to the connecting rod.
