Abstract: A mixed size product end of arm tooling is used in conjunction with a robot to pick mixed size product and place the product onto a pallet or layers resting on top of a pallet. The end of arm tooling includes two center rails/forks mounted to a base. Two outer rails/forks are mounted to linear bearings that guide the outer rails/forks when moving inwardly or outwardly from the center rails for pre-sizing to the product. Pusher arms are formed of two outer pusher arms and one center pusher arm. These pusher arms are attached to linear bushings that guide the pusher arms forward and backward. The pusher arms push off the product simultaneously as the robot is withdrawing the rails.

Abstract: An auxiliary air supply system which is utilized in association with an engine including at least one exhaust gas driven turbocharger for compression of ambient air. The system further includes low and high pressure auxiliary air compressor for further compression of the compressed air discharged from the turbocharger. The amount of power supplied to each compressor is regulated by a control system responsive to an engine parameter and the auxiliary air pressure.

Abstract: A conveyor system is disclosed in which a plurality of free-wheeling conveyor rollers are rotated by means of a driven belt which intermittently contacts the conveyor rollers when driven motion is desired. The rollers may also be braked by means of a second belt member which may contact the conveyor rollers at those times when the driven belt is out of contact with the rollers.

Abstract: A hydraulic system for motion amplification is disclosed. The system provides hydraulic fluid on both sides of a pair of hydraulic cylinders, creating a pressurized closed loop which provides precision control during both forward and reverse strokes of each hydraulic piston.

Abstract: An apparatus is disclosed for intermittently dispensing sheet material from a roll to an operating apparatus. The apparatus includes means for accumulating sheet material from the roll which does not require the roll to be motor driven and means for preventing pull back of the sheet material through the dispensing apparatus and permitting low force advancement of the sheet material.

Abstract: An adjustable sealing mechanism for heat sealing packages in plastic film is disclosed. The sealing apparatus includes means for vertically adjusting the position of the heat seal to accommodate objects of varying heights while maintaining a vertically controlled heat seal at the ends of the object.
