  • Selectible transport-servo velocity profile for document transport
    Patent number: 5274242
    Abstract: Disclosed are Power Encoder means for imprinting MICR characters on checks, with optical check-sensing means disposed along a check-transport path, including optical skew-sensor means and a transport control arrangement for advancing checks past processing stations according to one or several "velocity-profiles", depending upon the type and/or condition of the check.
    Type: Grant
    Filed: January 3, 1992
    Date of Patent: December 28, 1993

  • Document transport control including document velocity profiles
    Patent number: 5120977
    Abstract: Disclosed are Power Encoder means for imprinting MICR characters on checks, with optical check-sensing means disposed along a check-transport path, including optical skew-sensor means.
    Type: Grant
    Filed: February 19, 1991
    Date of Patent: June 9, 1992
    Assignee: Unisys Corporation (Formerly Burroughs Corp.)
    Inventors: Thomas Dragon, John Hylan, Robert Reynolds, Paul Merchant, Kenneth Berkoben
  • Servo means for document-transport
    Patent number: 5105363
    Abstract: Servo methods and apparatus whereby unit-record documents are transported past a process-station according to one of several "velocity-profiles", depending upon document type and/or condition, the methods involving: using a microprocessor whereby the documents are transported past one or more process-stations according to one of several "velocity-profiles", depending upon document type and/or condition.The methods involve arranging the microprocessor to store at least two different velocity-profiles and to store prescribed characteristics of each contemplated document and deploying passage-sensors along the path in prescribed spaced-relation with the process stations, whereby a given velocity-profile is automatically selected, in real time, and on-the-fly, by the microprocessor for each said document transported.
    Type: Grant
    Filed: October 10, 1989
    Date of Patent: April 14, 1992
    Assignee: Unisys Corporation
    Inventors: Thomas Dragon, Robert Reynolds, John Hylan
  • Servo for controlling document transport
    Patent number: 5084626
    Abstract: Disclosed are "anti-wander" web-transport arrangements wherein web-means are intermittently advanced, while being monitored for misalignment along the transport-path, and also being automatically urged back into proper alignment along this path.
    Type: Grant
    Filed: February 4, 1991
    Date of Patent: January 28, 1992
    Assignee: Unisys Corporation
    Inventors: Thomas Dragon, John Hylan, Kenneth Berkoben
  • Document-skew detection with photosensors
    Patent number: 5021676
    Abstract: Disclosed are Power Encoder means for imprinting MICR characters on checks, with optical check-sensing means disposed along a check-transport path, including optical skew-sensor means including a pair of area-photo-sensor means, one on each side of the check whereby the differential output thereof indicates "degree of skew".
    Type: Grant
    Filed: October 10, 1989
    Date of Patent: June 4, 1991
    Assignee: Unisys Corp.
    Inventors: Thomas Dragon, John Hylan, Robert Reynolds, Paul McCarthy, Paul Merchant, Kenneth Berkoben
  • Web transport with anti-skew arrangement
    Patent number: 5021673
    Abstract: "Anti-wander" web-transport arrangements wherein web-means are intermittently advanced, while being monitored for misalignment along the transport-path, and also being automatically urged back into proper alignment along this path. Preferably, this is done with left and right roll means, one of which is selectively urged more tightly against the web to impart superior advance-thrust and so urge the web back into proper alignment.
