One end of the attachment may be a clip connector means for fastening the attachment means to the floatable object and may also be attached to the rod. Alternatively, if the decoy has a receiver aperture above the keel, the anchor-weight attachment means comprises an adapter to provide for such attachment.

Abstract: An energy generation and storage system that uses a buoyant balloon suspended in a fluid and connected by a tether to a reel. The tether is taut and keeps the balloon from rising due to the buoyant force. A motor can do work to wind the reel in such a way that the balloon is pulled down against the buoyant force. Energy can be extracted from the system by allowing the balloon to rise, pulling on the tether and turning the reel that is connected to a generator. The generator and the motor can be the same unit, or they can be independent units which both connect to the reel.

Abstract: The present invention comprises a deepwater anchor that combines the high holding capacity of a plate anchor with the simple installation procedures associated with torpedo anchors. The complex embedding procedure typical for plate anchors is avoided. Instead, the anchor is installed by allowing it to free-fall through the water and then impact into the seabed. After penetrating the seabed, a pull on the anchor line causes the deployment of initially folded flukes. In their deployed positions, one or more flukes or plate-like structures extend perpendicularly toward the anchor shank, and function similar to conventional plate anchors. As a result of the fluke deployment, the holding capacity of the anchor against uplift loads is significantly greater than with a conventional torpedo anchor. Another aspect of the invention relates to the modular construction of a torpedo anchor, wherein the properties of an anchor can be adapted to the specific conditions determined at the deployment site.

Abstract: Ground anchors, in particular tent stakes (100), comprise one or more inherently flexible tines (110), a ground compression plate (160), and various tie points (420, etc.) for attaching a guy rope or the like to the top of anchor. The compression plate extends perpendicularly or at a large angle to the tine so that when the guy rope pulls on the anchor, the tine will tend to rotate about an underground fulcrum so that the compression plate will press against the ground and help the anchor resist pullout. The anchors are driven into the ground with a hammer or mallet. The tie points include hooks (420), closed holes (520), and swivel types comprising vertical members (810) with restraining, bulbous tops (820). An additional spring tie point (1600) can be inserted into optional lugs (1094, 1096) in the compression plate. The stakes can be driven into the ground vertically, or at an angle for additional holding force in some situations. They can also incorporate angled compression plates (160H, 160I).

Abstract: A hand-held tool for a diver has a hollow tube to vent pressurized gas from an interconnected source through an opening in the tube. The vented pressurized gas aerates material of a seabed, and an anchoring system disposed adjacent to the tube is effortlessly inserted in the aerated material by a single diver.

Different sources of pressurized gas for aerating the material may include a portable gas cylinder, diver's air tank, or hose from a remote source, such as a compressor. Quick-change connectors can be used to quickly and easily connect and disconnect components to supply more gas or add different components that will help insert different anchoring systems.
