  "abstract": "A zoned vacuum gripping tool comprising one mounting flange, four suction cups, one ejector, one manifold, four zone branches and one vent valve. When the suction cups reach the workpiece, the suction cups are evacuated by the ejector. After the workpiece has reached the set-down position, the vacuum circuit is vented by the vent valve. The arrangement is a proposed configuration composed from a typed library of mechanism blocks derived from published patents; it has not been constructed.",
