Abstract
Gyroscopic apparatus in which the rotor is elastically-connected to its drive, whereby deflection of the rotor bends the connection and thus sets up a deflection torque which acts upon the rotor. The connection of the rotor to the drive also includes masses carried by springs. When the rotor deflects, these masses oscillate in directions parallel to the driving axis, and when the rotor is spinning at a certain (tuning) speed the sum of the oscillating forces exerted upon the rotor by the individual moving masses will be a steady quantity which may be made equal and opposite to the deflection torque. The apparatus may thus behave like a "free rotor" gyroscope.
