Abstract
A thermally controlled servo system in which a member supporting the drive for a device to be accurately positioned is moved relative to a stationary support member in response to changes in temperature of an elongated, tensioned member. Changes in temperature of the tensioned member are achieved by regulating the current flow through the tensioned member in accordance with a control signal derived from an error signal generated by the device to be positioned.
