Abstract: A marine barrier gate includes a pleated row of buoyant panels movable between an expanded position and a retracted position, where the panels are substantially parallel. A first buoy is attached to a first end of the panel row, and a second buoy is remote from the panels when the panels are in the retracted position. The second buoy has a tow winch and cable attached to a second end opposite the first end, for moving the panels from the retracted position to the expanded position. The first buoy comprises a catenary winch and cable movably engagable with the panels and attached to the second buoy. When the panels are in the retracted position, the catenary winch sets a length or tension of the catenary cable such that it absorbs catenary loads on the barrier when the panels are moved to the expanded position by the tow winch.

Abstract: A security barrier system includes a security barrier unit including a first panel group, a second panel group, a connecting member for connecting the first panel group and the second panel group. The first and second panel groups are disposed substantially in parallel and face each other. Each of the first and second panel groups includes one or more sub-panel groups, each of which includes barrier panels arranged in line, intermediate members each disposed between adjacent barrier panels, rope tubes and ropes. Each barrier panel has a front face, a rear face and side faces and has channels passing through from one side face to another side face. The rope tubes are disposed in the channels, respectively, so that the rope tubes pass through the barrier panels and the intermediate members. The barrier panels and the intermediate members are connected by the ropes disposed in the rope tubes.

Abstract: Embodiments of this invention describe a float for use with a running gear entanglement system (RGES) deployed on water, in addition to an improved system and method for using an RGES deployed in water. The floats lock securely onto the RGES mainline rope. The floats may be stacked for additional buoyancy or to allow for multiple RGES ropes in the same deployment. The floats are designed to permit the RGES to be retrieved/stored on and deployed from a reel. The floats may be constructed of any color and may also be luminescent. The floats may be ballasted to assist in anchoring the RGES.

Abstract: A module for a wave attenuation system formed by connecting a plurality of panels in a structure positioned in a body of water, causes the dissipation of wave energy. Different configurations of panel, having different flow characteristics, used in the structure, and different types of connector used to connect panels, create different patterns of water flow within the structure, and contribute to wave energy dissipation. Units deployed in harbors, rivers, marinas and the like, help to prevent beach erosion and can facilitate beach nourishment. Embodiments can be utilized as a security barrier, preventing intrusion by trespassers, divers or various sized boats. A variety of sensors can be mounted to the structures, enabling detection of movement, chemical and biological agents, explosives or radiation. A submersible gate, comprising panels and a buoyancy control mechanism, allows for passage of boats and can be controlled remotely.

Abstract: A floating breakwater system comprises a plurality of modules that are flexibly affixed together. The modules are affixed together to make up a plurality of vertical panels made up of the modules and the vertical panels themselves are flexibly affixed together in generally parallel relationship. Each individual module has a front face that faces the oncoming wave. There are at least two inlets in the front surface and corresponding outlets in the rear surface and passageways between the inlets and the outlets such that the water propelled by the wave passes through the at least two passageways. Each passageway is tapered inwardly in the direction of the flow of the water and each passageway has a main longitudinal axis. The respective axes are angled inwardly toward each other and converge at a point displaced rearwardly from the outlets so that the water that passes through the passageways intersect at the point and the energy of the wave is dissipated.

Abstract: Embodiments of this invention include describe an improved apparatus and method for using ropes with security units/barriers deployed in water or on land. The ropes are preferrably deployed with hollow plastic tubes which protect the ropes from abrasion, UV light, and damage from animals. A rope contained within a tube is under no stress until an intruding object impacts the security barrier and the security barrier reaches its elastic limit.

Abstract: The Cu.sup.+.sup.+ cations of highly siliceous zeolites are found to undergo spontaneous reduction to Cu.sup.+ cations upon dehydration and to produce oxygen by oxidation of water.

Abstract: Dehydration of hydrated crystalline zeolites containing trivalent metal cations results in the concurrent reduction of the trivalent cation to the bivalent state and the evolution of oxygen. Rehydration of the zeolite produces free hydrogen and oxidizes the bivalent metal cations to their initial trivalent state. A cyclic operation of the two procedures is advantageously employed.
