A drive assembly for driving an implement is provided. The drive assembly includes a gear drive mechanism comprising a first drive gear rotatable about a first axis of rotation; a second drive gear rotatable about a second axis of rotation and engaged to the first drive gear; a driven member driven by the second drive gear, engaged to the implement, and rotatable about a third axis of rotation; a lobe; and a flexible link engaged to the first drive gear and the lobe, the flexible link comprising a first loop engaged to the lobe and a second loop engaged to the first drive gear. The drive assembly also includes a handle member engaged to the gear drive mechanism and configured to drive the lobe. The implement is rotated about the third axis of rotation as the handle member is moved from an unfired position to a fired position.

A throttle body having an integrated sector gear which includes a sector gear component, a bushing integrally formed with the sector gear component such that the bushing and sector gear component are a single part, and an insert, where the bushing and the sector gear formed around the insert. The insert includes a first arm and a second arm, and the insert is configurable to be formed with the sector gear and the bushing to be suitable for use with one or more packaging requirements of the throttle body.

The invention relates to a spring controller for high- or medium-voltage electric switchgear, the controller having a free-wheel coupling device between a crank handle or a motor and the drive shaft (1) for driving a switch contact of the switchgear and respectively providing coupling while the spring(s) (11) is/are being loaded and decoupling while the spring(s) is/are being released. The free-wheel mechanical device is incorporated in a toothed wheel (2) of the controller and includes at least one pawl (7, 70) meshing or not meshing with an inner set of teeth (4) of the toothed wheel (2).
