.~> Working member actuated by the rise and fall of a surface of a body of fluid {9}
DEFINITION
Classification: 60/495
(under the class definition) Apparatus having a working member which may be made buoyant or which is buoyant in a fluid and which may be caused to be moved by the fluid, because of the difference in specific gravity between the member and the fluid, to have a vertical component of motion and thereby adapted to do work, through a mechanical output means, either (1) because of a means which may make said buoyant member more or less buoyant so that it may be moved either against or by the pull of gravity in said fluid, or (2) though its specific gravity remains constant, the buoyant member may be given a vertical component of motion as a result of the rise and fall of the surface of said fluid.
(1) Note. The rise and fall of the surface of the buoying fluid may be the result of a natural phenomenon or under the control of other means.
(2) Note. The buoying fluid may exist in nature as a stream or ocean, or it may be confined wholly within a container wherein the flow to or from the container from any source of supply may be controlled, or it may be partially confined in a means which permits constant or controlled communication with a naturally existing body of fluid.
