Abstract
Abstract A propulsion device comprises two symmetrical wheels mounted in the same plane for rotation about parallel axes at right angles to the plane and driven synchronously in opposite directions. Each wheel carries a pair of gearwheels which rotate around the axis of the wheel with the wheel and support eccentrically a pair of planet masses. The masses are arranged such that their distance from the axis of rotation of the wheel increases and decreases under control of the gearwheels. At a position immediately prior to the maximum distance of the planet from the axis, an electromagnetic device restrains outward movement of the planet mass so that when released the planet mass provides whip-like action inducing a resultant force in a direction at right angles to the plane containing the axes of the wheels.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
206 words
Apparatus for developing a propulsion force comprising two symmetrical bodies, support means mounting the bodies for rotation about parallel spaced first axes and driving means for synchronously rotating the symmetrical bodies about the respective axes in opposite directions, each body including a pair of planet masses, means mounting each planet mass on the respective body, said mounting means being arranged such that the respective mass can freely rotate eccentrically about a second axis parallel to the first and such that the second axis rotates with the body about the first and moves radially relative to the first in timed relation to the rotation of the body so as to move during each cycle of rotation of the body from a position of minimum spacing to a position of maximum spacing and back to the position of minimum spacing from the first, and means for cyclically inhibiting and releasing rotation of the planet mass about the respective second axis so as to cause the planet mass to pivot inwardly relative to the first axis whereby said releasing causing a force outwardly of the first axis with the bodies arranged such that a resultant force from said forces lies at right angles to a plane adjoining the axes.
