Abstract: An aircraft control surface actuator assembly 12 is provided, including a flight control surface 14. A mechanical drive mechanism 18 is in communication with the flight control surface 14. An actuator rod assembly 24 is mounted to the mechanical drive mechanism 18 and includes a first segment 26 having a first segment outer diameter 34 with a plurality of first segment outer threads 36. A second segment 38 has a split sleeve passage 50, a second segment inner diameter 40 with plurality of second segment inner threads 42, and a second segment outer diameter 44 a plurality of second segment outer threads 46. The second segment inner threads 42 engage the first segment outer threads 36. A third segment 52 includes a third segment split sleeve passage 60 as well as a plurality of third segment inner threads 58 engaging the second segment outer threads 46. Rotation of the second segment 38 causes the first segment 26 and third segment 52 to move in opposing lateral directions.

Abstract: An automatic safety shut-off system for installation in a gas line or other fluid line which automatically shuts off the flow of fluid in response to an emergency situation. The system is characterized by three valves, each responsive to a different emergency situation. The first valve includes a sealing piston which is controlled by a pressure responsive locking mechanism which responds to above normal gas line pressure. The second valve responds to lower than normal pressure downstream of the shut-off system. The third valve responds to the interruption of electrical power supplied to machinery using fluid from the gas line. The pressure responsive locking mechanism of the first valve includes two locking toggle joints movable between a locked and an unlocked position. When in the locked position, the toggle joints retain the sealing piston in the open position, thereby allowing fluid flow through the valve.
