  • Heddle transfer stop motion in a triaxial weaving machine
    Patent number: 3998250
    Abstract: In a triaxial weaving machine heddles arranged in opposing rows are shifted in opposite weftwise direction with the leading heddle in each row being transferred to the trailing position in the opposite row. This invention provides means for stopping the weaving process if a heddle being transferred is not, at the end of the transfer operation, aligned with a slot to guide the heddle during a heddle shedding operation.

  • Sequence controller
    Patent number: 3984699
    Abstract: A sequence controller, employing digital techniques, employs clock pulses to energize and deenergize incremental loads sequentially at spaced intervals to correct the deviation of a sensed condition from a setpoint. The clock is inhibited from producing pulses when no deviation requiring correction exists. A feedback provides anticipation for the effect of the energization and deenergization of condition changing loads. Hunting is substantially eliminated.

  • Method employing a lead holder to retain a lead connection on an electrical coil
    Patent number: 3936931
    Abstract: A method employing a wire holder to retain side-by-side lead and magnet wires, joined together at adjacent ends, in a fixed position with respect to and insulated from a magnet coil on which it is mounted. It relieves strain on the magnet wire.

  • Control of heating and cooling available from central sources to a multi-zone temperature controlled space
    Patent number: 3933197
    Abstract: Incremental heating and cooling sources are energized and deenergized as required to meet the maximum heating and cooling demands of any of the zones in a temperature controlled space. Common references and comparators are employed for both heating and cooling controls.

  • Injection molding control
    Patent number: 3932083
    Abstract: The control system for an injection molding machine providing successive fill, compaction, hold, cure and mold open times. The ram position and mold pressure are monitored at predetermined times respectively after the molding cycle has begun. If the ram position is out of tolerance, the fill pressure is adjusted to compensate for the deviation. If the mold pressure is out of tolerance, the compaction pressure is adjusted to compensate for the deviation in mold pressure.
