Claim 1
Independent Claim
136 words
A GYROSCOPE COMPRISING A SEALED CHAMBER ROTATABLE ABOUT AN AXIS, POWER MEANS FOR RAPIDLY ROTATING THE CHAMBER ABOUT SUCH AXIS, A GYRO-ROTOR MOUNTED IN THE CHAMBER AND COMPRISING AN ANNULAR PORTION OF SUBSTANTIAL WEIGHT, A FAIRING PORTION SECURED TO AND ENCLOSING EACH SIDE OF THE ANNULAR ROTOR PORTION, THE ANNULAR PORTION AND ITS FAIRING PORTIONS BEING SMALLER IN DIAMETER THAN THE CHAMBER SO AS TO BE SPACED INWARDLY THEREFROM WHEN THE AXIS OF THE ANNULAR ROTOR PORTION IS CO-INCIDENT WITH THE AXIS OF CHAMBER ROTATION, A QUANTITY OF LIQUID OF GREATER SPECIFIC GRAVITY THAN THE GYRO-ROTOR COMPLETELY FILLING THE SPACE BETWEEN THE GYRO-ROTOR AND THE CHAMBER, AND A RESILIENTLY COMPRESSIBLE MEMBER EXPOSED TO THE LIQUID FOR COMPRESSION THEREBY UPON AN INCREASE OF PRESSURE ON THE LIQUID FOR ABSORING PRESSURE CHANGES CAUSED BY THERMAL EXPANSION AND CONTRACTION.
