  • Patent number: 5609659
    Abstract: A cyclical machine for forming at least one glass container each machine cycle comprising a plurality of controllers for controlling regulators and/or profiled motion actuators, at least one displaceable structure, controllers controlling the operation of all the other controllers, each of the controllers including repetitive sequencer and operable in any of a plurality of states, the one controller determines the critical time when each of the states should begin, and instructs each of the other controllers to begin any of the states at the associated determined critical time.
    Type: Grant
    Filed: June 21, 1995
    Date of Patent: March 11, 1997
    Assignee: Emhart Glass Machinery Investments Inc.
    Inventors: George T. Peterson, Timothy J. Liska, Can Nguyen, John W. McDevitt, Kevin N. O'Connor, George J. Collins
  • Patent number: 5562751
    Abstract: An I.S. machine system has a number of mechanisms which are driven by an inverter drive and a number of machine and section mechanisms which are driven by profiled motion actuators which are controlled by repetitive sequencers associated with each actuator. These repetitive sequencers are synchronized by taking the reference signal from a master clock which supplies the reference signal to the inverters and converts it to a once/cut sync signal for the machine mechanisms operated by profiled motion actuators and to a once/cycle sync signal for the section mechanisms and controllers.

  • Patent number: 5271756
    Abstract: An I.S. machine is made up of a plurality of independent individual sections for receiving gobs of molten glass and for forming the gobs into glass containers. A gob distributor delivers gobs to the sections. The controller of these sections and the gob distributor are synchronized by means for generating a once per cut signal, a divide by N circuit where N is the number of sections which are to have gobs distributed to them, means for defining N, means for applying N to the divide by N circuit, means for supplying the once per cut signal to the divide by N circuit, and means for distributing the output signal of the divide by N circuit to each of the section and gob distributor controllers.
