Abstract: A gravity-assisted rotational mechanism and a generator device cooperating therewith. The gravity-assisted rotational mechanism includes multiple concentric rotational members having different sizes and rotatable about the same rotational center, several link members having equal weights for driving the same, and at least one connection member for pivotally connecting the rotational members with the link members. The rotational members can symmetrically push/pull each other. The link members and connection member are respectively mounted on interference sections of at least some of the rotational members to absorb gravitational energy. The energy of the link members is transmitted via the interference sections to the rotational members to form a cycle of energy storage and transmission, whereby the gravity-assisted rotational mechanism can lastingly continuously self-rotate as an ornamental device.

The energy of the link members is transmitted via the interference sections to the rotational members to form a cycle of energy storage and transmission. In condition of low energy loss, the gravity-assisted rotational mechanism forms a continuously swinging self-revolving device for lasting watching.

Abstract: The present invention discloses an apparatus and a method for breaking up air bubbles in a liquid flow which is conveyed in a fluid conduit by providing sharp protuberances on the inside wall of the conduit. The sharp protuberances break up large air bubbles into small air bubbles or micro-bubbles such that they can be easier disposed of after passing through a liquid dispensing nozzle. Various designs on the inner wall of the present invention fluid conduit can be provided as long as sharp protuberances exist for dividing the bubbles.
