Abstract: A drying rack used primarily for air-drying wet glassware, which utilizes modular pegs that are installed on drying racks of differing materials of construction.

Abstract: Integration or application of an energy producing wind turbine to an exhaust system. The wind turbine is rotated by the exhaust system discharge air to produce energy. The wind turbine does not disperse potentially hazardous discharge air in an unsafe manner.

Abstract: A device for holding advertising media in a frame, usually constructed of aluminum extrusion which houses glass that protects and covers the advertising poster. Wherein the poster is changed periodically to promote different types of products or services.

Abstract: An undersea optical repeater is provided. The repeater includes at least first and second pressure vessels for use in an undersea environment. Each of the pressure vessels includes a pressure housing and at least two cable receiving elements disposed on opposing ends of the pressure housing for respectively receiving ends of optical cables that each include an electrical conductor therein. The cable receiving elements are adapted to be in electrical contact with the respective electrical conductors in the optical cables. The pressure housing is adapted to provide electrical isolation between the respective cable receiving elements attached thereto. At least one optical amplifier is located in each of the pressure vessels. Each of the optical amplifiers includes at least one electrical component adapted to receive electrical power from the electrical conductors in the optical cables.

Abstract: The flow of air through a fume hood is optimized by producing a bi-stable vortex within the vortex chamber of the fume hood regardless of sash movement. A bi-stable fume hood optimizes capture face velocity to minimize backflow of fume laden air through the hood sash opening. This bi-stable vortex fume hood reduces the energy consumption up to sixty percent versus the present day mono-stable vortex fume hoods. The bi-stable vortex fume hood utilizes a vortex pressure control system to reposition top, center, and bottom slot openings of a baffle in the hood. This baffle moves the bi-stable vortex away from the fact when the sash is fully opened and creates a clearing action near the work surface as the sash is closed. The fume hood's airfoil is placed inside the fume hood chamber and the airfoil has multiple entry pattern, one of which turns the vortex up and away from the open sash window. The other creates flow which washes the work surface of the hood.

Abstract: A novel concrete core support structure for nuclear reactors is described.

Abstract: A liquid metal circulation system is disclosed which is suitable for use in connection with a nuclear reactor. The circulation system of the invention includes an electromagnetic pump having a central core body featuring a helically configured, six pole magnet, optionally directing flow to one or a series of flow couplers, which generates sufficient liquid metal flow to be used as the primary circulation means for the nuclear reactor. The increased safety, design simplicity, and efficiency of such circulation system overcomes many of the drawbacks of conventional circulation systems.

Abstract: A double tube modular coil steam generator is provided in which a multiplicity of inner tubes conducting water are individually surrounded by outer tubes containing liquid metal as a heat transfer agent. The double tubes form into coils, providing a large surface area while conserving space. Immersion of the double tube coil in hot liquid metal, e.g., from the core of a nuclear reactor, causes efficient transfer of heat across the liquid metal in the outer tube to the water in the inner tube, creating superheated steam, which can be cycled to a turbine and converted to electrical power.The efficiency, reliability and safety of the multiple double tube design of the steam generator obviates the necessity of many secondary heat removal and emergency components in addition to conserving space and material. The modular design allows ease of operation, fabrication and repair.

Abstract: A nuclear reactor is provided characterized by a circulating liquid metal cooling system comprising a heat exchanger having a closed intermediate heat transfer fluid circuit in the form of a helical coil juxtaposed with the liquid metal coolant system, which effectively transfers heat through the intermediate circuit to a secondary fluid circuit. The intermediate heat transfer fluid circuit, which completely separates the liquid metal cooling system from the secondary fluid circuit, prevents potentially dangerous reactions between the primary liquid metal coolant and the secondary fluid (e.g., water).The efficiency, reliability and safety of the heat exchanger features eliminates the need for many secondary heat removal and emergency components in the design of the nuclear reactor.

Abstract: Disclosed is a nuclear reactor employing a liquid metal and containing a reactor vessel, and at least one satellite vessel, and a hot and a cold leg connecting means which combine to form a continuous pathway for the flow of the liquid metal between the reactor vessel and the at least one satellite vessel. Each of the hot leg and cold leg connecting means contain a bellows assembly which are readily accessible for repair or replacement without draining the reactor vessel of the liquid metal.
