Number: 464/1
Name: Rotary shafts, gudgeons, housings, and flexible couplings for rotary shafts > Speed responsive device for adjusting relative rotational position of coupled members
Description: Flexible coupling structure wherein a shaft and another member are mounted for relative rotation about a common axis and wherein means is provided to sense velocity or change of velocity of the shaft or other member and responsive to such sensed velocity or change of velocity, said means acts directly or indirectly to alter the relative rotational position of the shaft and other member between predetermined relative rotational positions.
