Abstract: The machine includes a motor (1) with an output shaft for driving a first roll (10) for driving an endless grinding belt (60). A second guide roll (20) and a third guide roll (50) extending parallel to the first roll are mounted in a support structure (20, 25). The second roll can be moved outwards using a spring device (46) into an end position at a radial distance from a midpoint of a triangle defined by the three rolls. The second or third roll can be moved to a given distance from the triangle to allow the machine to be adapted to different circumference grinding belts. The motor is supported by an undercarriage (2) which keeps the motor shaft horizontal when resting on the ground. The support structure can be pivoted relative to the motor so that the angle relative to the vertical plane for grinding part of the part between the second and third rolls can be altered by changing the angle of the support structure relative to the horizontal plane.

Abstract: A thyristor 1, 2, 3, 4 has a plurality of field effect transistors, for example, 41, 75, 2, 76, 73, 74 of depletion type or enrichment type, distributed over the cathode surface, for short-circuiting of the thyristor's cathode emitter junction 4, 2. A conducting pattern 73, 83, insulated from the cathode contact 6 and the semiconductor body constitutes the grid of the field effect transistors and connects the grids to each other. In order to eliminate the influence of possible defects in one or more of the transistors and increase the manufacturing yield, one first locates possible defects and determines their type, after which, in the case of defects due to short circuiting of the conducting pattern 73, 83, or in the case of transistors of depletion type, the conducting pattern is cut out from a region c with defective short-circuiting function of the transistors in such a way b that the pattern within a region for each defect is isolated from the rest of the pattern. For transistors of enrichment type, at the defects d due to faulty short-circuit function of the transistors, a region e around the defect is doped in such a way that within the doped region the transistors are converted to transistors of depletion type.

Abstract: An actuating device for a vehicle hydraulic brake system of the type having electromagnetically operated valves in the hydraulic circuits to each wheel brake for providing slip control wherein the device includes a master cylinder having a brake pedal force responsive hydraulic booster piston for actuating a master cylinder piston slidably mounted within a slidable positioning sleeve within the bore of the master cylinder. The positioning sleeve is adapted to be mechanically coupled to the booster piston in the brake actuation direction. A stationary projection on the interior end of the master cylinder protrudes into the positioning sleeve and cooperates with the sleeve and master cylinder piston to vary the master cylinder volume. A hydraulic change-over valve directs pressurized fluid during operation of the slip-control valves to the positioningsleeve in opposition to the actuating force to reset the brake pedal and supply pressurized fluid to the wheel brake lines to replenish fluid depleted during operation of the slip control cycle.

Abstract: A piston sealed by a rolling membrane is arranged in a cylindrical housing comprising two components and this piston translates against the force of a return spring. A vibrating armature pump driven via two wires by a variable alternating voltage serves for operating the positioning drive. The vibrating armature pump draws hydraulic fluid from a reservoir chamber through an inlet opening and transports the hydraulic fluid through a return valve and through a first orifice into a pressure chamber. The piston is displaced downwardly conjointly with a piston rod. The pressure generated by the vibrating armature pump is dependent upon the applied voltage. A state of equilibrium between this pressure and the counterpressure of the spring arises such that the positioning drive is suitable for continuous control or regulation operations. The return valve comprises a membrane valve which decisively influences the intended working characteristics of the positioning drive, since it responds to small differences in pressure.
