Abstract: A guided vehicle relocation device has a frame. The frame has an opening to allow one or more wheels of a vehicle to enter an interior area of the frame. At least one drive mechanism is coupled to the frame. The drive mechanism engages the wheel of the vehicle, rotating the wheel of the vehicle to move the vehicle. A control panel is coupled to the frame and to the at least one drive mechanism. The control panel is used for controlling operation of the guided vehicle relocation device.

Abstract: A measuring instrument for measuring the distance from a hole, drilled at the intersection of a rib and a stringer, to the adjacent flange of the rib includes two arms projecting laterally out from the side of the instrument and forward to engage the flange. The arms are geared together at their inner ends within the body of the instrument to insure that the angles of both arms relative to the longitudinal axis of the body are equal to each other so that the longitudinal axis of the instrument in use remains perpendicular to the face of the flange. A spring loaded conical hole-centering probe protruding from the bottom face of the instrument fits into and centers itself in the hole and establishes a reference from which the flange is measured. A stylus, slidably mounted in the instrument and protruding from the front end thereof, contacts the face of the flange.
