7285. Wimperis, H. E., and Elphinstone, G. K. B. March 23. Gyroscopic apparatus.-An instrument for indicating the rate of angular movements, for instance the rate of roll of a ship, by gyrostatic precession, consists of a gyrostat a mounted in a ring b the turning movement of which is controlled by a torsion spring or wire c. The movement of the ring b about its axis is a measure of the rate of angular movement of that axis in the plane of the ring, and is transmitted through the quadrant b<2> to the pointer e.
