Claims

1. AN APPARATUS FOR MEASURING ANGULAR ACCELERATION, SAID APPARATUS COMPRISING:

A RING MEMBER;

SUPPORT MEANS FOR SUPPORTING SAID RING MEMBER AT DIAMETRICALLY OPPOSED POINTS ON SAID RING MEMBER, SAID SUPPORT MEANS BEING RIGIDLY CONNECTABLE TO A BODY ADAPTED TO BE SUBJECT TO ANGULAR ACCELERATION;

A PAIR OF MASSES SUPPORTED ON SAID RING MEMBER AND MOUNTED THEREON AT DIAMETRICALLY OPPOSED LOCATIONS WHICH ARE EQUIANGULARLY DISPOSED RELATIVE TO SAID SUPPORT POINTS;

A RIGID MEMBER INTERCONNECTING SAID MASSES;

A PLURALITY OF STRESS SENSING MEANS MOUNTED ON SAID RING MEMBER FOR SENSING STRAINS INDUCED IN SAID RING MEMBER BY INERTIA OF SAID MASSES WHEN SAID APPARATUS IS SUBJECTED TO ANGULAR ACCELERATION, AT LEAST ONE OF SAID STRESS SENSING MEANS BEING LOCATED BETWEEN EACH SAID MASS AND SUPPORT POINT;

AND INDICATING MEANS RESPONSIVE TO SAID PLURALITY OF STRESS SENSING MEANS FOR INDICATING MAGNITUDE AND DIRECTION OF ANGULAR ACCELERATION OF SAID APPARATUS.
