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...

A scanning electron beam CT system generates an electron beam along a beam source axis offset from the scanner axis, or axis of symmetry, thereby permitting the X-ray subject to pass completely through the stationary gantry. The electron beam is produced with the first drift tube region of an evacuated housing chamber, and is directed downstream toward a second region that includes a gantry. A sca...

The rubber curing bag for vulcanising tyres or air springs is made from at least two separate rubber layers(A',B'). In the mfr. of. the curing bag, a preform(5) is constructed of two or more layers of different rubber cpds., placed as a ring in a vulcanising mould(1) and on closure of the mould halves(2,3) is pressed against a metal core(4) and/or the tool halves before vulcanisation. During mould...
