    摘要： The likelihoood of successful transfer of a blind rivet (12) from a loading device (16) to the nose (20) of a blind rivet setting tool is substantially improved by conforming the end surface (38) of the nose (20) which receives the blind rivet (12) to the convex surface (40) of the blind rivet flange (30) which is received and by making the inner diameter of the nose bore (18) correspond to the inner diameter of the convex rivet surface (40).

    摘要： Process for welding a weld stud onto a workpiece by means of a drawn arc, in which the weld stud is placed onto the workpiece and, with performance of a welding stroke, is removed from the workpiece in a return stroke, igniting a pilot arc, and is advanced toward the workpiece again in a forward stroke during the combustion of a connected welding arc. The welding arc is divided by pulse-wise current reduction to a minimum value into a sequence of current pulses and the last of these current pulses is extended in time by at least about 1.5 times relative to the preceding current pulses. This extended current pulse lasts substantially to the end of the forward stroke.

    摘要： A printed circuit board 10 is clamped to the rail of an X-Y table 17 by a pair of clamping assemblies 22 which each have a support rail 16 carrying a number of pivotally displaceable clamping elements 26. These clamping elements 26 are spring biassed to the clamping position and will be simultaneously released by displacement of a control bar 32 carrying pins 34 which will engage the clamping elements 26 to displace them to a release position.
