  • Patent number: 5089759
    Abstract: A position controller controls the direction and degrees of rotation of an electrical motor output shaft in response to a stored control program. The stored control program contains a plurality of profiles, each including a plurality of successively executed steps defining the operation sequence of the motor. Each step includes programmed instructions defining a predetermined amount of rotation of the motor output shaft and a predetermined event which must occur before the step is executed. In one embodiment, the controller selectively controls the speed of the motor in each step. The controller supplies a signal, programmed in each step, to a variable frequency A.C. drive which correspondingly varies the frequency of A.C. power supplied to the motor to vary the operating speed of the motor.

  • Patent number: 4460966
    Abstract: Transfer machine apparatus is provided, which includes a load station for receiving parts during at least some of the part reception periods in a succession of part reception periods, and which further includes a number of selectively located work units for performing prespecified work tasks upon received parts. A transfer mechanism is provided for moving a given one of the received parts from the load station to each of the work units in a prespecified sequence, the given received part being moved from one work unit to another during a part transfer cycle in a succession of part transfer cycles. A digital code storage device receives a digital code during each of the part reception periods, a first digital code being received if a part is received by the load station during a part reception period, and a second digital code otherwise being received.

  • Patent number: 4055386
    Abstract: A control system for adjusting the cutter of a boring machine or the like to compensate for cutter wear and other cutting dimensional changes such as those due to temperature variations which is specially adapted for use with a gage for measuring a dimension of a part machined by the tool and which is responsive to a signal from the gage indicating the magnitude and the sense of the variation of the dimension of the machined part relative to a nominal dimension for adjusting the tool the entire amount needed to compensate for the variation in a single adjusting operation.
