A high concentration central receiver system and method provides improved reflectors and a unique heat removal system. The central receiver has a plurality of interconnected reflectors coupled to a tower structure at a predetermined height above ground for reflecting solar radiation. A plurality of concentrators are disposed between the reflectors and the ground such that the concentrators receive reflective solar radiation from the reflectors. The central receiver system further includes a heat removal system for removing heat from the reflectors and an area immediately adjacent the concentrators. Each reflector includes a mirror, a facet, and an adhesive compound. The adhesive compound is disposed between the mirror and the facet such that the mirror is fixed to the facet under a compressive stress.

A geodome tower reflector for a beam down optics solar power system has three equidistantly spaced tower assemblies. A geodome reflector assembly is movably mounted to the plurality of tower assemblies for vertical movement along the plurality of tower assemblies. The geodome reflector assembly has a facet support structure. The facet support has a plurality of rigid frames to which facets are mounted. Each facet has a downwardly facing mirror for reflecting light from a heliostat to a receiver of the beam down optics solar power system.

A clip for securing lobster trapping equipment to a buoy. The clip has an elongate tubular body through which a rope attached to a lobster trap is threaded. The rope is then threaded through a buoy loop and clipped to the outer wall of the elongate tubular body by a pair of hooks. The clipped rope extends through a slot formed between the pair of hooks. The slot has oppositely facing sets of teeth which grab the rope and prevent its release under normal rope tensions, ie rope tensions caused by the motion of the sea. However, under certain extreme rope tensions, such as a whale entangled in the rope, the teeth are specifically designed to be unable to hold the rope under the extreme tension and will allow the rope to slip back through the teeth, slot and hooks to become disengaged with the outer wall of the clip and from the buoy.

A valve assembly for transferring fluid from a fluid supply tank to a fluid holding tank. The valve assembly includes a housing having a first port for communication with the fluid supply tank and a second port for communication with the fluid holding tank. A drum is rotatably mounted in the housing and has a passageway therein. The passageway has an opening located at each end thereof positioned on an outer surface of the drum for alignment with one of the ports in the housing. The drum is rotatable between a flow position in which the openings are aligned with the ports to permit fluid flow from the fluid supply tank to the fluid holding tank and a shut-off position in which one of the openings is not aligned with the ports to prevent flow from the supply tank to the holding tank. The valve assembly further comprises an actuator for rotating the drum within the housing between the fluid flow and shut-off positions. The housing is sealingly engageable with the fluid supply tank around a periphery of an aperture in the tank for sealingly closing the aperture in the tank.

A power system provides various levels of electrical power at various radio frequencies to specific input locations of a neutral particle beam accelerator system. Both the power system and the accelerator system are mounted on a space platform. The power system includes separate modules mounted on two hinged members of the platform. The modules utilize turbines, generators and fuel cells to provide the needed electrical power which is amplified to the desired levels required by the accelerator system. In addition, a fuel cell is utilized to power a pulse drive motor to drive the generators during turbine start up in order to provide high voltage output power during the start up. A regenerator produces hydrogen and oxygen from the water effluent produced by the fuel cells and the combustors which powers the turbines thereby recycling the fuel and working fluid and consequently making the power system generally non-contaminating and fuel efficient. A thermal management subsystem circulates hydrogen through both the accelerator and power systems, and the hydrogen is utilized as both a coolant and a fuel/working fluid for power production thereby enhancing the energy efficiency of the power system.

Modular, hybrid power system

A photovoltaic electric power system for use in space. A self contained sun powered electric power generating system comprising a fresnel mirror array made up of a plurality of quadrilateral mirrors individually mounted on a generally flat supporting structure with the mirrors aimed at a common point above the structure, a photovoltaic array positioned at the common point by a movable strut mechanism, heat exchanger means at the PV array to draw excess heat therefrom, coolant lines from the heat exchanger means running through the struts to transfer heat to heat pipes configured as flat panels at the edges of and perpendicular to the supporting structure, and positioning means attached to a separate structure to enable the system to track the sun. The system is designed to fold into itself in the form of an elongate box for launch, maneuvering and protection.

A heat pipe radiator coating of a fibrous material provides protection for the radiator, such as a heat pipe, pumped loop, etc., while allowing good emissivity and heat rejection. Fibers are constructed from fiberglass, glass, quartz, saphire, diamond, carbon carbon, tantalum, stainless steel, aluminum, beryllium, and copper, and may be coated with a variety of metallic materials.

A process and resulting structure for a window typically used on weapons with infrared sensors. The window has a plurality of transparent blocks connected in a mosaic pattern. Between the blocks are slots, that allow a coolant to flow through and cool the window, such that the window does not have a thermal signature.

A rolled belt heat exchanger utilizes the increased heat transfer due to a large, extended surface belt. Heat is transferred from a heated roller to the belt, and then allowed to radiate to space as the belt follows a generally flattened oval path away from the heated roller.

Apparatus for providing automatic alignment of beam devices having an associated structure for directing, collimating, focusing, reflecting, or otherwise modifying the main beam. A reference laser is attached to the structure enclosing the main beam producing apparatus and produces a reference beam substantially parallel to the main beam. Detector modules containing optical switching devices and optical detectors are positioned in the path of the reference beam and are effective to produce an electrical output indicative of the alignment of the main beam. This electrical output drives servomotor operated adjustment screws to adjust the position of elements of the structure associated with the main beam to maintain alignment of the main beam.

Precision alignment device

A sonic flow plate assembly for controlling the mass flow rate of gases by use of the sonic choking phenomenon. Identical gas flow control plate portions, each containing a plurality of nozzles formed by the smooth internal surface of vertical passageways in the plates, are connected end-to-end to form a unified gas flow control plate. Each of the nozzle passageways is in the shape of a hollow inverted truncated cone with bases in communication with hollow cylinders. Each plate portion, including the passageways therein, are molded from a fiberglass composite. The connected plate portions are secured in place by transversely positioned tension rods.
