Abstract
A system for stopping rotation of a first gear and a second gear on a shaft, The first gear and second gear are concentric and rotatable about said shaft. The first gear and the second gear are driven by the same input system and the first gear and the second gear are configured to rotate at differential speeds and independently to each other. The first gear comprises a first end stop and the second gear comprises a second end stop and the first end stop and the second end stop are configured to engage each other when the first gear and the second gear have each rotated a predetermined number of turns. Engagement of the first end stop with the second end stop is configured to prevent rotation of the first gear and the second gear and cause a stall in the system.
