Abstract
A fast-acting, self-resetting hydride actuator comprising an enclosure containing hydrogen, and an actuating means communicating with the interior of the enclosure responsive to changes in pressure of the hydrogen gas and adapted to provide an actuating force based upon a change in pressure of the hydrogen gas. The actuator also comprises an electric resistance means inside the enclosure which includes a resistor element made in whole or in part of a hydridable electric conductor and means for passing electric current through said resistor element.
