Abstract: A locking clutch to selectively transmit torque from a stator of a downhole tool to a rotor of the downhole tool includes at least one locking pawl disposed upon the rotor, wherein the at least one locking pawl comprises a load path, at least one pivot axis, and a mass center, wherein the at least one locking pawl is biased into an engaged position by a biasing mechanism, wherein the at least one locking pawl transmits force from the stator to the rotor along the load path when in the engaged position, and wherein centrifugal force urges the at least one locking pawl into a disengaged position when the rotor is rotated above a disengagement speed.

Abstract: A motor drive unit assembly for a motorized drapery system having a drapery fabric can include a motor having a drive shaft, an output member rotatable about a drive axis, such that rotation of the output member about the drive axis causes the drapery fabric to move, and a clutch member operatively coupled between the drive shaft of the motor and the output member. The clutch member is configured to automatically couple the output member to the drive shaft such that rotation of the motor drive shaft causes the output member to rotate about the drive axis when the motor drives the drive shaft. The clutch member is further configured to automatically decouple the output member from the motor drive shaft so that the output member rotates about the drive axis relative to the motor drive shaft when the output member is manually driven.

Abstract: A clutch assembly having a driver, an output member, a clutch spring, an armature and an actuator. The clutch spring includes a plurality of coils that are configured to be drivingly engaged with the driver. The clutch spring further includes first and second ends. The first end is configured to drivingly engage the output member to facilitate the transmission of rotary power from the driver, through the clutch spring and into the output member. The second end is engaged to the armature. The actuator is selectively operable for rotating the armature relative to the driver in a rotational direction opposite a predetermined rotational direction in which the driver is driven to thereby initiate at least partial disengagement of the coils of the clutch spring from the driver.
