Abstract: A linear motor is movable along a substantially flat stator. Electrical, mechanical and pneumatic drive sources are coupled to the linear motor through an umbilical cord. A strain relief member, normally linked to the linear motor, is towed by the linear motor to the desired position along the platen. The strain relief member is then decoupled from the linear motor, and is magnetically (or vacuum) attracted and temporarily "locked" to the platen. A portion of the umbilical cord is clamped to the strain relief member at a point intermediate the ends thereof. The length of umbilical cord between the clamp and the linear motor hangs loosely to provide sufficient "play" between the strain relief member and the linear motor. The strain relief member, being "locked" to the platen isolates any pulling or pushing forces of the umbilical cord from being exerted upon the linear motor thereby enabling the linear motor to retain its precise position.

Abstract: An electrical safety disconnect device inserted in overhead power wires to prevent live broken wires from contacting the ground or persons in their vicinity. The device takes the form of a male-female plug combination that automatically separates when the wire experiences a predetermined force generally less than that required to break the wire itself.
