Patent number: 10844507Abstract: The present disclosure relates to an apparatus for electroplating an element. The apparatus may comprise a cathode cage assembly. The cathode cage assembly may include a cage member and at least one electrically conductive wire extending along at least a portion of the cage member. The wire may be arranged to form at least one volume within the cage member for retaining an element within the cage member. The cage member and the wire permit a degree of movement of the element during an electroplating process while retaining the element within the volume.Type: GrantFiled: April 27, 2018Date of Patent: November 24, 2020Assignee: Lawrence Livermore National Security, LLCInventors: Thomas L. Bunn, Corie Horwood

Patent number: 8485741Abstract: A method and apparatus for generating an image. Light is passed though an opening of a housing. The light has an intensity. At least a portion of the light received through the opening is increased using an intensifier unit to form intensified light. The intensified light is converted into a number of signals for the image using an image detection system located inside of the housing.Type: GrantFiled: June 17, 2010Date of Patent: July 16, 2013Assignee: The Boeing CompanyInventors: Thomas L. Bunn, Lynne C. Eigler

Patent number: 8405322Abstract: A method and apparatus are present for increasing an intensity of light. Light is sent into an input of a housing in which a vacuum is substantially provided in the housing. The light sent into the input of the housing is converted into initial electrons. Movement of the initial electrons is caused to diverge from an axis through the housing to form diverged electrons. Additional electrons are generated to form an increased number of electrons in response to receiving at least a portion of the diverged electrons. The increased number of electrons is converted into output light that exits an output of the housing.Type: GrantFiled: June 17, 2010Date of Patent: March 26, 2013Assignee: The Boeing CompanyInventor: Thomas L. Bunn

Patent number: 8377384Abstract: 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.Type: GrantFiled: April 8, 2005Date of Patent: February 19, 2013Assignee: The Boeing CompanyInventors: Thomas L. Bunn, Alan Z. Ullman, David Stelman

Patent number: 7195740Abstract: 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.Type: GrantFiled: March 29, 2004Date of Patent: March 27, 2007Assignee: The Boeing CompanyInventors: Thomas L. Bunn, Stephen C. Hurlock, Alan Z. 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: 6884337Abstract: 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.Type: GrantFiled: May 20, 2002Date of Patent: April 26, 2005Assignee: The Boeing CompanyInventors: Peter D. Amdisen, Thomas L. Bunn, Alan Z. Ullman
