Abstract: A floating wind farm includes a plurality of floating rafts connected with one another and being disposed in a body of water below the water by a predetermined distance; a plurality of wind turbines connected to the floating rafts respectively and being configured to be driven by wind and thereby generate power; a power generator connected to the floating rafts; a plurality of anchors connected to the floating rafts respectively and disposed in the body of water for confining the location of the floating rafts. Each of the floating rafts includes at least three pipes and a plurality of ballast blocks attached to the pipes. The pipes are configured to store air compressed by the power generated by the wind turbines. The power generator is configured to generate and output electricity from the compressed air stored in the pipes.

Abstract: A shoring device that utilizes an accessory assembly mounted to a vertical tubular member of a tubular scaffold assembly to receive a shoring member therethrough. With an adjustable threaded ring mounted over the threaded portion of said accessory assembly, a supporting surface or edge is provided to a locking pin that passes through cooperating slots in the accessory assembly and radial through holes in the shoring post member to keep the post member and the accessory assembly at a fixed position with respect to each other. The lower most end of the threaded portion comes in abutting contact with the upper end of the scaffold vertical member thus transmitting the bearing load therethrough. A user can selectively adjust the effective length of the scaffold and shoring assemblies by rotating the ring assembly.

Abstract: A new method for more rapidly renourishing a beach. A mobile accretion unit is set on the bottom a considerable distance out from the beach, yet still within the region where sand is deposited by wave action. This accretion unit collects sand over time. It is gradually raised to keep it from burying itself. The unit eventually creates a small sand “island,” which is typically located one hundred feet or more from the beach. A chain of such small sand islands are preferably created along the shore. Radiating sets of linear fences are then placed on each island. These fences radiate out into the surrounding water. The linear fences trap additional sand and serve to increase the size of the islands. Linear fences extending from the islands to the beach may be used, as well as linear fences extending between adjacent islands. Eventually the islands grow together and merge with the prior beach, thereby creating a new beach along the position of the islands.

Abstract: A portable barrier including an elongate hollow container providing a chamber for holding fluent material to increase its weight has a stabilizing toe projecting outwardly from one of its sidewalls with the upper surface of the toe disposed at an angle relative to the horizontal and angling downwardly on progressing away from sidewall. Hinged connectors are provide at opposite ends of the barrier for connecting to adjacent barriers, and angled endwalls accommodate angular orientation of adjacent connected barriers relative to each other. A plurality of bores permit fluid to flow pass the barrier as desired, or to be stopped by the insertion of plugs. A removable flexible cover is placed over the hinged interconnection between adjacent barriers. The cover may be of a water-proof or filtering medium as desired.

Abstract: The object of the present invention to provide a method for thawing frozen ground for laying concrete primarily at a construction site by use of a continuous length of circulating hose placed on the frozen ground inside and/or adjacent a concrete form where the concrete will be laid, covering the circulating hose with a layer of aggregate material for insulation from cold air caving the ends of the circulating hose protruding from the aggregate connecting the ends of the hose to a source of heated liquid to circulate warm liquid through the circulating hose to thaw the frozen ground, laying the concrete in the concrete form while continuing to circulate heated liquid in the circulating hose to prevent the concrete from freezing, leaving the portion of the hose in the form under the concrete by cutting the ends protruding from the aggregate, removing the remaining portions of the hose.
