Abstract: A pneumatic clutch actuator includes an actuator housing, a piston assembly, a bearing carrier, and a locking element. The piston assembly is disposed within the actuator housing and is movable between a first position and a second position. The piston assembly has a piston head, an elongate member extending from the piston head, and a lock ring coupled to the elongate member. The bearing carrier supports a bearing and is slidably disposed on a portion of the actuator housing. The locking element is operatively connected to the piston assembly and engages the bearing carrier to adjust a total length of the piston assembly as the piston assembly moves from the second position towards the first position to compensate for wear of the clutch assembly.

Abstract: A clutch actuator assembly includes a drive member, a threaded rod including a first end operatively connected to the drive member, a second end, and an intermediate portion including a plurality of threads extending therebetween. A member is threadably engaged with the plurality of threads of the threaded rod, a clutch actuator member is arranged at the second end of the threaded rod, and a velocity brake is operatively coupled to the threaded rod. The velocity brake decelerates rotation of the threaded rod.

Abstract: A spring scale, in particular for weighing loads in the ?g-mg range, comprises a load platform suspended by at least three flexural springs in a surrounding frame, and has bridge-connected strain gauges arranged for measuring strain on one side of the flexural springs. The flexural springs extend in succession along substantially the whole periphery of the load platform in a gap between the load platform and the inner edge of the frame, and an attachment spot on the load platform for every flexural spring is arranged substantially directly opposite or past an attachment spot on the inner edge of the frame for a next flexural spring in the succession of springs. Preferably, the spring scale is made in one piece, and manufactured by means of semiconductor process technology.
