DEFINITION
Classification: 60/501
(under subclass 497) Apparatus having a unitary buoyant member having means actuated in response to the relative movement between said member and a means supported entirely by said member.
(1) Note. The device may be in the form of a free hanging weight carried within the buoyant member, or it may be a means in the form of a sea anchor, or other means, which is suspended from the member outside the member or in the fluid (not in engagement with the earth) to dampen the movement of the means given it by the member so that work may be produced as a result of the relative movement between the member and the means when the member is caused to change its vertical position responsive to the vertical movement of the free surface of the fluid.
