Patent number: 7158554Abstract: A solid generator laser provides device simplicity and fuel regeneration without relying upon highly-corrosive or unstable fuels. The laser system includes a fuel supply system that provides a solid fuel to a laser. The laser processes the fuel products to produce at least a solid waste product and a gaseous waste product. A fuels regeneration system receives the solid and gaseous wastes at a reagent production system to replenish the fuel products in the fuel supply system. Rather than relying upon corrosive fuels such as BHP, then, the laser suitably processes solid peroxide (e.g. Na2O2) and a halide (e.g. hydrogen or deuterium halide) to form a salt, water and singlet delta oxygen that may be used to induce a lasing effect. The processes and structures described herein may be used, for example, with chemical oxygen iodine lasers and the like.Type: GrantFiled: August 1, 2003Date of Patent: January 2, 2007Assignee: The Boeing CompanyInventors: Alan Zachary Ullman, David Stelman

Patent number: 7106777Abstract: A phase-change heat exchanger is provided for thermally conditioning a fluid. The phase-change heat exchanger includes, but is not limited to, conduits configured to convey the fluid through the phase-change heat exchanger and a foam structure in thermal contact with at least one of the conduits. The foam structure has ligaments interconnected to form a three-dimensional reticulated structure of open cells. A phase-change material is contained within the open cells and the phase-change material is configured to receive thermal energy of the fluid from the ligaments of the foam structure.Type: GrantFiled: December 8, 2003Date of Patent: September 12, 2006Assignee: The Boeing CompanyInventors: Adon Delgado, Jr., Randall Gene Leonard, Alan Zachary Ullman

Patent number: 7025868Abstract: An electrolytic cell for producing chlorine and basic hydrogen peroxide suitably includes an anode partition and a cathode partition separated by a membrane. The cathode partition is divided into a catholyte compartment and a gas plenum by a gas diffusion cathode. The anode partition electrolyzes alkali chloride received from the laser to produce free chlorine and alkali ions. The catholyte partition reduces oxygen received from the gas plenum through the cathode, and produces alkaline peroxide from the oxidized components combined with alkali ions received through the membrane from the anode partition. The cell is particularly useful in a fuel regeneration system (FRS) for a chemical oxygen iodine laser (COIL).Type: GrantFiled: January 7, 2003Date of Patent: April 11, 2006Assignee: The Boeing CompanyInventors: Thomas L. Bunn, Alan Zachary Ullman

Patent number: 6674781Abstract: A method of utilizing lithium hypochlorite and hydrogen peroxide to generate singlet delta oxygen, which is used as fuel for a COIL device. The invention also comprises a method of regenerating lithium hypochlorite from the side products of singlet delta oxygen production. Singlet delta oxygen is produced by reacting LiOCl with H2O2 to form LiCl, H2O, and O2(1&Dgr;). The singlet delta oxygen is used to power a COIL apparatus, and the remaining aqueous LiOCl/LiCl solution is considered a byproduct stream. The reactant hydrogen peroxide (H2O2) is preferably supplied as a vapor and the reactant LiOCl is supplied as a LiOCl-rich LiOCl/LiCl aqueous solution. Water is removed from the LiCl-rich LiOCl/LiCl aqueous byproduct stream and the LiCl in the byproduct stream is regenerated under basic conditions into LiOCl and water. The water that is removed from the byproduct stream is converted into hydrogen peroxide through a catalytic, electrochemical, or chemical process.Type: GrantFiled: August 19, 2002Date of Patent: January 6, 2004Assignee: The Boeing CompanyInventors: Robert Allen Dickerson, Alan Zachary Ullman

Patent number: 6650681Abstract: A sealed exhaust chemical oxygen-iodine laser (SECOIL) employing a sealed exhaust system (SES) is described. The SES is capable of selectively condensing and cryosorbing various chemical species contained in the laser-exhaust gas. Additionally, a condensable diluent is employed. The SES is configured so that the diluent and other condensables can be removed in a first stage with a high temperature condensing bed, while the oxygen can then be removed in a second stage in a low temperature sorbing bed. The result is a reduction in the weight, volume, and power consumption of the SECOIL system, especially the SES component thereof.Type: GrantFiled: April 25, 2000Date of Patent: November 18, 2003Assignee: The Boeing CompanyInventors: Alan Zachary Ullman, Jan Vetrovec, Arthur H. Bauer, William E. McDermott

Patent number: 6366594Abstract: A wavelength selective laser system and associated method are provided that produce laser beams having wavelengths that are only slightly different, but that permit a composite return signal to be selectively processed in accordance with the wavelengths of the signals that comprise the composite return signal. The wavelength selective laser system includes first and second lasers for producing respective laser beams. Each of the first and second lasers define a nominal gain spectrum. However, the wavelength selective laser system also includes a magnetic field generator disposed about the second laser for altering the gain spectrum of the second laser such that the wavelengths of the laser beams produced by the first and second lasers differ by at least one part per million. As such, the first laser will emit signals having a first wavelength and the second laser will emit signals having a second wavelength.Type: GrantFiled: September 28, 1999Date of Patent: April 2, 2002Assignee: The Boeing CompanyInventors: Arthur Henry Bauer, Alan Zachary Ullman
