Patent DE-3582486-D1 (DE)
IPC: G05D17/02
Filed: 1985-12-20
Granted: 1991-05-16
Abstract: The invention relates to a power screwdriver (1) having a gearbox (2) and an electric motor (3). The invention is based on the knowledge that the electric motor (3) gives a maximum and predetermined torque under load during standstill or near standstill, said torque being dependent on the available voltage or the load current corresponding to the respective characteristic curve of the motor. For limiting the torque, a control element (triac 10) for controlling a preselectable voltage present on the electric motor (3) or a preselectable load current is provided in the load circuitry (5) of the electric motor (3). This voltage or the load current can be adjusted on a set potentiometer (19) connected to the control element, whereby the maximum torque at standstill of the motor or the turn-off torque at low motor speeds can be varied and adjusted accordingly. In a further embodiment in connection with the use of an AC motor, a mains compensation circuit (22) is provided for equalising mains voltage fluctuations, said mains compensation circuit (22) comparing a constant voltage with the mains voltage and, in the case of deviations, adjusting the voltage supplied by the set potentiometer (19) such that mains fluctuations with respect to the maximum torque are equalised. <IMAGE>

Abstract: The present invention relates to a regenerative pump having a casing with a casing inlet and casing outlet, an impeller disposed on a shaft and containing at least one bucket ring with axially and radially open bucket compartments on the first and second side of the impeller, and mutually separated side channels having an entrance port, an exit port and an interrupter. The arrangement herein is such that the conveying streams on the two sides of the impeller are separated from each other. The entrance ports of the side channels on the two impeller sides are in communication with the casing inlet, and the exit ports are in communication with the casing outlet, so that the conveying streams are first subdivided and then recombined. The entrance port, the exit port, and the interrupter in opposition to the first impeller side are arranged to be offset in the direction of rotation of the impeller by such an angular amount with respect to the corresponding elements on the second impeller side that the radial forces on the first impeller side, resulting from the pressure differences in the conveying streams between the inlets and the outlets, are counterbalanced by radial forces on the second impeller side that are the same with respect to amount but are effective in the opposite direction. In this way, compensation of the radial forces acting on the pump shaft is attained.

Abstract: An instruction processor suitable for use in a reduced instruction-set computer employing an instruction pipeline which performs conditional branching in a single processor cycle. The processor treats a branch condition as a normal instruction operand rather than a special case within a separate condition code register. The condition bit and the branch target address determine which instruction is to be fetched, the branch not taking effect until the next-following instruction is executed. In this manner, no replacement of the instruction which physically follows the branch instruction in the pipeline need be made, and the branch occurs within the single cycle of the pipeline allocated to it. A simple circuit implements this delayed-branch method. A computer incorporating the processor readily executes special-handling techniques for calls on subroutines, interrupts and traps.

Abstract: The machine removes burrs from slabs (1) issuing from a continuous casting plant and cut to length by an oxygen cutting. The machine is of the type having a rotor mounted horizontally in a frame and carrying on its periphery means for removing the burrs. The burr removing means are self-retractable hammers (8) whose head (10) describes an envelope which is rendered substantially tangent to the lower side of the slab (1) by means (40, 36) for moving the rotor (4) vertically in translation carried by the frame (21, 22). The rotor (4) is driven by a driving shaft (51) whose rotation is controlled in one direction or the other by a control device as a function of the detection (C1, C2, C3) of the passage of the head end or foot end of the slab.

Abstract: A hit-scoring target for shooting practise having several mutually bonded layers, a first layer (2) at least the outside surface of which is electrically conductive, a second, electrically nonconductive, at least semi-rigid layer (4) imparting mechanical strength to the first layer and made of a material tolerant of the heat of a freshly fired projectile, a third, electrically nonconductive layer made of an elastically resilient material (6), a fourth layer (10) of which at least the surface contacting the third layer is electrically conductive, and a fifth layer (12) serving as a backing and imparting relative rigidity to said target.
