Apparatus for immobilizing a working shaft at a predetermined angular position

A positioning drive with an electronic regulator for controlling the r.p.m. of a working shaft has a regeneratively coupled amplifier with variable negative feedback adjustable from a normally high value to a minimum value for the final braking action, whereby the shaft is abruptly brought to rest a...
