Abstract: Systems and methods are provided for compacting objects onto tools. One embodiment is a method for compacting an object onto a rigid tool. The method includes placing an object onto a surface of a rigid tool, disposing an end effector over the object, spreading linkages of the end effector, causing a scroll of material between the linkages to be disposed atop the object while surrounding the object, and applying a negative pressure to the scroll that offsets air leaks between the scroll and the object, thereby forming a suction hold that compacts the object onto the rigid tool.

Abstract: An electrical receptacle having at least one plug-receiving receptacle socket comprising a two-piece housing having contact fingers which are spring biased against a center post of the housing by a coil spring. The coil spring is interposed between the ends of a flexible shunt member which electrically interconnects the contact finger with the bus-bar member, the bus-bar member having suitable wire-connecting screws. Thus, the load force on the contact fingers prevents accidental removal of a typical two-prong electrical plug when positioned in the receptacle socket.
