Usborne Accelerating Gear was equipment designed by Cecil Vivian Usborne that was fitted to an F.T.P. range receiver to allow it to indicate ranges when the range dial was not uniformly scaled.
Although some cam worked sights had different range cam dials for use with firing with full charge, reduced charge and sub-caliber weapons, not all did, and the accelerating gear permitted their existing dial to be appropriated by mapping the range being sent into a synthetic one that would be equivalent on the dial mounted on the sight.[1]
