Abstract
1,219,890. Pumps operating by electromagnetic interaction with fluids. H. H. HERMAN JR. 8 Jan., 1968, No. 38480/70. Divided out of 1,219,415. Heading H2A. [Also in Division G1] In a gyroscope having a conductive fluid as its inertia mass, the fluid is contained in a hollow sphere 1 and is caused to rotate by a rotating magnetic field in a broad equatorial band of the sphere, there being a plurality of pairs of diametrically spaced contacts 5 penetrating the sphere and being connected to a source of electrical power 9 and to a respective current sensing device 8 so that as the sphere tilts, different pairs of contacts engage the fluid and the respective current sensing device indicates the angle of tilt of the sphere. The rotating field is produced by coils 4, the current sensing device may be a lamp or relay and the fluid may be a gas or vapour or liquid, e.g. mercury, or a non-conductive liquid containing particles of conductive solids. In a modification, Fig. 2 (not shown), a plurality of coils are placed around the sphere so that as the sphere tilts, different pairs of contacts 5 operate relays (e.g. 16, 18) to energize different coils and so maintain the fluid in its initial plane of rotation.
