Abstract
A gyrocompass having a capsule, mounted to float in an air-tight fashion, for at least one electrically driven gyro. The capsule is produced from two mutually adapted shells which are sealed with respect to one another and consist of a high-strength, corrosion-resistant material which is a good electrical conductor. A steel alloy, titanium alloy, or a high-strength conducting plastic material is suitable. The device avoids electrically insulated bushings on the bottom and edge sides, substantially simplifying the configuration of an equatorial azimuthal tap. The mechanical stability of the capsule is conspicuously improved, and the official HSC requirements for fast ships are readily met.
Claims8
A gyrocompass comprising, in combination:
- a) at least one electrically driven gyro;
- b) said gyro being mounted in a gas-tight capsule and supplied from an external current source through a capsule wall;
- c) said capsule being mounted to float in an electrically conducting liquid inside a compass casing;
- d) said capsule comprising two mutually adapted shells which are sealed with respect to one another;
- and
- e) each of said shells consisting of a high-strength, corrosion-resistant electrically-conductive material.
