An engine turning clock work motor including two shape memory alloy (SMA) torque tube actuators, ratcheting mechanisms, and gearing. The gearing communicates the SMA torque tube actuators with a common gear that applies torque to a shaft, so that while one torque tube is heated and applying torque, the other torque tube is relaxed (using a cooling mechanism). The ratchet prevents the relaxing torque tube from applying torque in the incorrect direction.

A variable speed ratio transmission comprises a support structure, an input member, an output member and a plurality of planet wheels which are supported rotatably on the support structure and which receive the movement from the input member. Each of the planet wheels comprises a connecting rod which is rotatably connected thereto in the region of a first end thereof and which supports at an opposite end thereof a unidirectional connection wheel which entrains in rotation the output member. The transmission further comprises a variation device for the spacing between the pivot axis of the connecting rods and a respective rotation axis of the planet wheels.

A device for displaying at least one time-related magnitude including a timepiece movement including at least one time base and at least one energy source which extend in a first same plane, and at least one roller pivotably mounted about an axis of rotation A and which extends in a second plane parallel to the first plane, at least one roller including a display strip arranged on an outer periphery and on which at least one indication of the time-related magnitude is inscribed, the timepiece movement driving at least one roller in rotation about axis A via drive device which extend in the same second plane as at least one roller, at least one roller and the timepiece movement being centred on axis A.

A material mover assembly, comprising a chamber having an inlet and an outlet; a first paddle; and a second paddle, wherein the first paddle is positioned in and configured to rotate circumferentially in the chamber, the second paddle is positioned in and configured to rotate circumferentially in the chamber, or is configured to be inserted into and retracted out of the chamber, and wherein relative motion of the first paddle and the second paddle causes material to be pulled into the chamber via the inlet and pushed out of the chamber via the outlet in a forward direction. A material mover assembly may be reversible in pumping direction and further may be used as an energy generator in either direction.

A window blind includes an input mechanism adapted to change a location of a bottom rail, an adjustment output mechanism adapted to be motivated when the bottom rail is located at a low position, whereby to tilt slats between two positions, and an output clutch mechanism, which is adapted to be driven by the input mechanism to move the bottom rail toward a high position, and is adapted to be driven by the input mechanism to move the bottom rail toward the low position when it is at the high position. A stroke delay mechanism is provided on a transmission path from the adjustment output mechanism to the output clutch mechanism, which is adapted to delay an affected time for transmission. Whereby, only one single control module is required to adjust the inclination angle of the slats and to collect and expand the covering material.

A window blind includes a fixed rail and a plurality of slats hang below the fixed rail through a ladder tape. The slats are controlled by an output adjustment mechanism to change between a first state and a second state. In addition, an output clutch mechanism is provided to collect or to expand the window blind. Said output adjustment mechanism and said output clutch mechanism are both controlled by an input mechanism. Whereby, it requires only one single control module to adjust shielding of the slat assembly composed of the slats, and to expand or collect the slat assembly.
