A floating wind turbine platform includes a floatation frame (105) that includes three columns (102, 103) that are coupled to each other with horizontal main beams (115). A wind turbine tower (111) is mounted above a tower support column (102) to simplify the system construction and improve the structural strength. The turbine blades (101) are coupled to a nacelle (125) that rotates on top of the tower (111). The turbine's gearbox generator and other electrical gear can be mounted either traditionally in the nacelle, or lower in the tower (111) or in the top of the tower-supporting column (102). The floatation frame (105) includes a water ballasting system that pumps water between the columns (102, 103) to keep the tower (111) in a 10 vertical alignment regardless of the wind speed. Water-entrapment plates (107) are mounted to the bottoms of the columns (102, 103) to minimize the rotational movement of the floatation frame (105) due to waves.

Carbon Dioxide capture processes utilizing ammonia, or ammonia in water as the capture fluid for carbon dioxide generate concentrated solutions of ammonium carbonate species in water, which are subsequently decomposed to capture the carbon dioxide and recycle the ammonia. Forward osmosis processes utilize ammonium carbonate species as draw solutions to pull water from saline solutions such as seawater in the ammonium carbonate solution. The ammonium carbonate solution is then heated to decompose the ammonium carbonate to ammonia and CO2 which are both reused, while a portion of the aqueous stream is recovered as pure water. Combination of carbon capture process with an integrated forward osmosis process provide great economies over standalone operations. Furthermore, the very high concentrations of ammonium carbonate provide a further opportunity to include osmotic power recovery cycles with the integrated forward osmosis and carbon capture process.

A floating fish production system for placement within a body of water and being structured and disposed for containing fish and other aquatic animal, plant and algal species, the system including at least one primary containment tank having an arrangement of individual solid wall sections and an arrangement of individual solid floor sections. Flexible membranes span between and connect to adjacently positioned solid wall and floor sections to define flexible connecting joints that allow the individual solid wall and floor sections to move relative to one another in an articulating action. The flexible membranes allow the tank configuration to temporarily deform from a relaxed state in response to externally applied forces exerted on the tank (e.g., waves, wind, current) to thereby absorb the externally applied forces and reduce stress on the structural integrity on the tank. An air lift system including a high volume, low pressure blower and a spaced arrangement of vertically extending air lift pipes delivers water and oxygen from the exterior body of water and into the tank interior. A flexible main drain in a central area at the bottom of the tank connects to a waste recovery system for removing waste produced by the fish and other aquatic species.

A printing system is linearized automatically using measurements made with a simple optical sensor, such as a line sensor, that is onboard the system. The printing system itself is for forming images on plural printing media. Because the optical sensor is not a calorimeter or even a true densitometer, the sensor requires calibration, preferably based upon measurements using real inks. In the past it has been considered a requirement that such calibration be performed separately using each of the print media that was to be used for printing images. Linearization according to the invention, however, refers to a single calibration of the sensor, that calibration being used in common for essentially all media—even though the single calibration is performed with respect to exclusively a single one of the plural media.

A fixed-bed catalytic reformer unit is converted to moving bed reactor/cyclic regenerator operation by re-using the fixed bed reactors of the original unit as regenerator vessels operated in cyclic regeneration mode in a new catalyst regeneration section. A flow connection, suitably a liftpipe, is provided to convey spent catalyst from the spent catalyst outlet of a new moving bed reactor section to the converted regenerator section, together with a flow connection for regenerated catalyst from the regenerator section to the regenerated catalyst inlet of the new moving bed reactor section. A flow control distributor directs spent catalyst sequentially to each of the regenerator vessels to carry out the regeneration with regeneration gas. Each regenerator vessel is cycled through a fill, regeneration, discharge sequence to maintain a continuous flow of catalyst to and from the reactor section.

The invention relates to a method and an arrangement implementing the method for testing a transmitter part and receiver part in a transceiver. A signal in the transmitter part is mixed with a mixing signal for generating a signal to be connected to the receiver part, which generated signal is connected to the receiver part and the connected signal is compared with the transmitter part signal to test the transceiver. The mixing signal is generated by connecting a signal generated by means of a signal generator used in the operation of the transmitter part and/or receiver part to at least two signal branches, dividing the signal in the signal branches into at least two signals of different frequencies in the different signal branches, and generating a mixing signal from the signals of different frequencies.

A system and method of reducing the net carbon dioxide footprint of an industrial process that generates power from the combustion of hydrocarbon fuels in which ambient air is admixed with up to 50% by volume of an effluent gas from the power generator of the industrial process, in order to substantially increase the CO₂ concentration in the air prior to treatment. The treatment comprises adsorbing CO₂ from the admixed ambient air utilizing a cooled, porous substrate-supported amine adsorbent, wherein the porous substrate initially contacts the mixed ambient air containing condensed water in its pores, which act as an intrinsic coolant with respect to the exothermic heat generated by the adsorption process. In addition, prior to regenerating the supported adsorbent, air pressure is substantially reduced in the sealed regeneration chamber and the low pressure chamber is placed in fluid connection with a higher pressure regeneration chamber containing steam and carbon dioxide, to preheat the sorbent to be regenerated and to quickly cool the regenerated sorbent prior to use for further CO₂ adsorption.

A method of recovering carbon dioxide from a synthesis gas stream generated within a facility having a synthesis gas reactor, a water-gas shift reactor and a steam generation system for generating steam for the synthesis gas reactor and for export. After the synthesis gas stream is passed through at least one process heat exchanger of the steam generation system located downstream of the water-gas shift reactor, the temperature of the synthesis gas stream is increased while simultaneously adding steam to the synthesis gas stream. Thereafter, the synthesis gas stream is added to an absorption system having an absorption zone utilizing a solvent to absorb the carbon dioxide and a regeneration zone to disengage the carbon dioxide from the solvent and thereby regenerate the solvent. Heat is transferred from the synthesis gas stream to the regeneration zone to promote disengagement of the carbon dioxide from the steam and such that between about 40 percent and about 90 percent of the carbon dioxide originally present in the synthesis gas stream is recovered. The temperature of the synthesis gas stream can be increased and steam can be added thereto by mixing superheated steam with the synthesis gas stream. Alternatively, a synthesis gas stream can be introduced into a saturator utilizing a water stream that undergoes indirect heat exchange with a low pressure steam stream.

Disclosed is a method for annealing a silicon thin film in a substrate in which an insulation layer and the silicon thin film are subsequently formed. The method includes heating or preheating the silicon thin film within a temperature range at which the substrate is not transformed during the process so as to generate an intrinsic carrier therein, thereby lowering a resistance to a value at which Joule heating is possible; and applying an electric field to the preheated silicon thin film so as to induce Joule heating by means of movement of the carrier, thereby conducting crystallization, eliminating crystal defects, and ensuring crystal growth. When using the method, Joule heating is selectively induced to a-Si thin film, a-Si/Poly-Si thin film or a Poly-Si thin film according to the preheating condition, thereby making a Poly-Si thin film of good quality within a very short time without damaging the substrate.

A novel method to develop highly conductive functional materials which can effectively shield various electromagnetic effects (EMEs) and harmful radiations. Metallized nanotube polymer composites (MNPC) are composed of a lightweight polymer matrix, superstrong nanotubes (NT), and functional nanoparticle inclusions. MNPC is prepared by supercritical fluid infusion of various metal precursors (Au, Pt, Fe, and Ni salts), incorporated simultaneously or sequentially, into a solid NT-polymer composite followed by thermal reduction. The infused metal precursor tends to diffuse toward the nanotube surface preferentially as well as the surfaces of the NT-polymer matrix, and is reduced to form nanometer-scale metal particles or metal coatings. The conductivity of the MNPC increases with the metallization, which provides better shielding capabilities against various EMEs and radiations by reflecting and absorbing EM waves more efficiently. Furthermore, the supercritical fluid infusion process aids to improve the toughness of the composite films significantly regardless of the existence of metal.
