Dimpling of a workpiece by rebounding of a magnetic repulsion punch mechanism, when operated at high punching rates, is avoided by application of a damping pulse at a point at or subsequent to a mid-point of a return stroke of the punch from the workpiece and preferably within the last 10% of the return stroke. This damping pulse is preferably a fraction of the pulse width and of approximately the...

The invention concerns a method and device for separating the components of mixtures or suspensions in the centrifugal acceleration field of a centrifuge, flow-through centrifuge or ultra-centrifuge. During centrifugation, mixtures or suspensions are continuously or discontinuously fed into a centrifuge rotor system (5, 6, 12, 13) pre-filled with a fluid medium, and excess fluid and/or separated c...

The device has two serpentine grooves (3,4) in the tapered end of a drum (2) for guidance of a supporting cable and a safety cable which grips it in the event of breakage. Two coiled spring steel strips (7,8) within the drum are held together by flanges (9). The coils and cables are provided with separate automatic safety devices (15,25) to prevent fall of the load. A catch (26) is coupled to a p...

A sheet feeder 1 with closed frame side walls 10 comprises a main pile lifting unit 2, and an auxiliary pile lifting unit 5 for interruption-free sheet feeding to a sheet processing machine. The main pile S is supported on a lifting plate 6 driven by the lifting device 2, which includes lifting chains 7 and guide rails 8 installed on the interior of the side walls 10.
