GENERAL KNOWLEDGE

Detailed explanation-1: -Elmer Ambrose Sperry, (baptized Oct. 12, 1860, Cortland, N.Y., U.S.-died June 16, 1930, Brooklyn, N.Y.), versatile American inventor and industrialist, best known for his gyroscopic compasses and stabilizers.

Detailed explanation-2: -The first seaworthy gyrocompass was produced in 1908 by the firm of Hermann Anschütz-Kaempfe in Germany. It was largely made possible through the efforts of Max Schuler, who developed the principles on which a practical shipborne gyrocompass depends. This compass was a marvel of mechanical ingenuity.

Detailed explanation-3: -The Sperry Gyroscope Company was incorporated on April 14, 1910. It was reincorporated in New York as the Sperry Gyroscope Company, Inc., on January 21, 1929. In April 1933 it became a wholly-owned subsidiary of the Sperry Corporation and was merged into it as a division in December 1947.

Detailed explanation-4: -Gyrocompass is working with the high speed gyro rotor (gyroscope) to accurately seek the direction of true north. It operates by seeking an equilibrium direction under the combined effects of the force of gravity and the rotation of earth.
