摘要： Methods and apparatus are provided for the generation of hydrogen peroxide from an electrochemical (EC) cell arrangement. One embodiment of the apparatus comprises an EC cell having anode and cathode electrodes with a cation exchange membrane disposed between them to form anode and cathode compartments. An aqueous salt solution is supplied to the anode compartment and water and oxygen are supplied to the cathode compartment. An electric potential applied across the anode and cathode electrodes initiates an electrochemical process that results in the formation of an acid anolyte solution in the anode compartment and an alkaline catholyte solution in the cathode compartment. The anolyte solution and the catholyte solution are combined in a neutralizing chamber to form a neutral aqueous solution comprising hydrogen peroxide, salt, and water. The hydrogen peroxide is separated from the neutral aqueous solution by conventional means.

摘要： A method and apparatus for removing BHP contaminants (alkali hydroxide and H2O2) from a recycled aqueous alkali chloride solution stream before the stream is fed to a chloralkali cell so that the contaminants do not impair the operation of a chloralkali cell. Unwanted alkali hydroxide within the recycled alkali chloride brine solution is reacted with chlorine gas and converted into an alkali chloride, which is useful in the operation of the chloralkali cell, and oxygen gas, which is outgassed from the system. Any H2O2 remaining in the recycled stream after elimination of the alkali hydroxide is reacted with chlorine to form HCl and oxygen gas. The HCl raises the pH of the brine solution, after which the pH may be adjusted by the addition of supplemental alkali hydroxide.

摘要： A method of generating basic hydrogen peroxide (BHP) fuel for a chemical oxygen-iodine laser (COIL) using stored alkali chloride, typically potassium chloride, and water. The alkali chloride and water are mixed to form a saturated or nearly saturated aqueous salt solution for use as an anolyte feed to a chlor-alkali cell. The chlor-alkali cell generates alkali hydroxide, hydrogen, and chlorine. Water and oxygen are reacted to form peroxide which is combined with the alkali hydroxide from the chlor-alkali cell to form a dilute solution of BHP, a mixture of hydrogen peroxide and alkali hydroxide, which dissociates into O2H− and −OH. The BHP is concentrated and the molar ratio of hydrogen peroxide to alkali hydroxide is adjusted to 1:1 before the BHP is supplied to a COIL apparatus as fuel for the lasing process.

摘要： Methods and apparatus are provided to control flow separation of an ambient flow along a surface and about a turret, such as by reducing flow separation aft of the turret. By reducing flow separation, the resulting turbulence may be similarly reduced such that the performance of a system, such as a laser system, housed by the turret may be improved. To reduce flow separation, a motive flow may be provided by ejector nozzles that open through the surface and are positioned proximate to and aft of the turret relative to the ambient flow. The motive flow has a greater velocity than the ambient flow to thereby create a region aft of the turret of reduced pressure relative to an ambient pressure. Within this region of reduced pressure aft of the turret, a portion of the ambient flow mixes with the motive flow, thereby reducing or eliminating flow separation.

摘要： A system and methods for broad area visual obscuration around a platform. In one embodiment the system comprises a source of visible light, shaping optics and projecting optics. The system projects a light beam onto an illumination area in a sweeping pattern to repetitively illuminate all portions of the illumination area, such that a stationary observer within the illumination area receives repeating pulses of the light at a power, intensity, frequency and duration sufficient to visually impair the observer so as to substantially prevent the observer from discerning the platform between pulses. The light pulses are capable of temporarily blinding human eyes but incapable of causing permanent vision loss.

摘要： An apparatus and method for vaporizing liquid are provided which employ a plurality of rods disposed within a storage vessel that serve as the heat transfer element. While the plurality of rods are generally submerged by the liquid fuel to facilitate heat transfer and vaporization of the liquid fuel, the rods may be packed closely together such that the liquid inventory required to maintain the rods in a submerged state is substantially less than required by conventional fuel supply systems, thereby permitting the weight of a fuel supply system that incorporates the apparatus and method to be reduced while still permitting effective vaporization of the fuel.
