An electric control apparatus for machinery, especially for the control of the shearing flight of metal from laminators

摘要

An apparatus for controlling a computer according to the movement by linear or angular example of a body or associated member with equipment comprising a tachogenerator which is arranged to be rotated according to the movement and to give an output proportional to the value instantaneous velocity displacement means for integrating the output and means responsive to the magnitude of the integrated action to effect desired control over the computer when the integrated output and thus the displacement output reaches a predetermined value.
