  • Actuator mechanism
    Patent number: 4092874
    Abstract: An actuator mechanism having a frame, a shaft rotatably supported in the frame, a positioning mechanism coupled to the shaft for rotating the shaft in two rotary positions disposed approximately 180.degree. apart, and a pair of plungers coupled to the shaft each of which is responsive to a control signal for applying bi-directional rotation to the shaft respectively.

  • Cyclical bi-directional rotary actuator
    Patent number: 4010455
    Abstract: A thermally powered rotary actuator is disclosed which is used for positioning a shaft in first and second positions which are disposed 180.degree. apart. A pair of heat extensible springs are attached to the shaft and to the frame of the rotary actuator for selectively rotating the shaft from one of its two positions to the other position upon the application of heat to one of the heat extensible springs. The heat extensible springs are preferably constructed from the alloy 55-Nitinol. In the preferred embodiment, a detent mechanism is provided for locking the rotatable shaft in its two rotary positions.
