Abstract:
1. A positioning system comprising: a rotor rotatable about a central axis in a first rotary direction, said rotor having a generally annular radial portion disposed coaxially with said central axis, said radial portion having a diametric extent defined by a locus of diametral axes; and a rotary indexing assembly disposed within the diametral extent of the rotor radial portion, the assembly comprising: whereby with said follower being positioned in alignment with said first one of said diametral axes and with said biasing member biasing said follower in said second position, said first actuator in said de-actuated position, and said second pawl in said locking position, said first actuator is actuable from said de-actuated position to said actuated position effecting the movement of said follower from said second position to said first position and the movement of said second pawl from said locking position to said release position, and engaging said first pawl with the radial portion of said rotor effecting the rotation thereof in said first rotary direction by said indexing increment responsive to the rotation of said follower in said first rotary direction and into alignment with said second one of said diametral axes, and
