Abstract
The present invention is directed to a gyroscopic instrument comprising concentric containers, the inner container enclosing a rotating electric gyro rotor, magnetic fluid enclosed between the inner and outer concentric containers, and magnetic flux producing means mounted on at least one of the two concentric containers, so that magnetic fluxes reach the magnetic fluid to support the inner container without contacting the outer container. The magnetic flux producing means are preferably mounted and oriented on a line drawn on at least one of the concentric containers at predetermined distances so that magnetic fluxes transmitted from the pole of one flux means reach the opposite pole of an adjacent means by passing through the magnetic fluid.
Claims26
A gyroscopic instrument, comprising:
- a. a magnetic fluid,
- b. an outer container encompassing said magnetic fluid,
- c. an inner container enclosing at least one high speed rotating gyro rotor, being supplied with electric power from the outer container side and being positioned within said container, and
- d. magnetic flux producing means adjustably mounted on the outer container so that magnetic fluxes produced thereby reach said magnetic fluid to support said inner container free of contact with said outer container, said magnetic flux producing means comprising a pair of magnets which are oriented adjacent to one another with the north pole of one magnet facing the south pole of an adjacent magnet.
A gyroscopic instrument, comprising:
- a. a magnetic fluid,
- b. an outer container emcompassing said magnetic fluid,
- c. an inner container enclosing at least one high speed rotating gyro rotor being supplied with electric power from the outer container side and being positioned within said container, and
- d. magnetic flux producing means adjustably mounted on the outer container on a line drawn on said outer container at a predetermined distance between the adjacent magnetic flux producing means so that magnetic fluxes transmitted from the north pole of a magnetic flux producing means reach the south pole of at least one adjacent magnetic flux producing means through said magnetic fluid, thereby supporting said inner container to float free of contact with said outer container.
