Publication number: 20200277185Abstract: Methods and apparatus for improving the loading ratio of a hydrogen gas in a transition metal are disclosed. Blocking desorption sites on the surface of a metallic structure increases the partial hydrogen/deuterium pressure when the absorption and desorption processes reach an equilibrium. The higher the number of desorption sites that are blocked, the higher the equilibrium pressure can be reached for attaining a higher hydrogen loading ratio. Moreover, since hydrogen desorption occurs at grain boundaries, reducing grain boundaries is conducive to reducing the hydrogen desorption rate. Methods and apparatus for increasing grain sizes to reduce grain boundaries are also disclosed.Type: ApplicationFiled: January 23, 2017Publication date: September 3, 2020Inventors: Darren R. Burgess, Michael Raymond Greenwald, Brent W. Barbee

Publication number: 20200017962Abstract: Methods and apparatus for increasing vacancies in a metallic structure are disclosed and for improving a hydrogen loading ratio in the metallic structure. The metallic structure comprises one or more transition metals or metal alloys. The metallic structure is prepared by forming a metal organic precursor and reducing the precursor to a metallic structure, in which a coordination number of the metal atoms is reduced and the vacancies in the metallic structure are increased.Type: ApplicationFiled: March 28, 2018Publication date: January 16, 2020Inventors: Darren R.

Publication number: 20190077657Abstract: A gas-loading and packaging system is provided for loading a material used in a hydrogen fuel cell with gas and packaging the material in a sealed container. The gas may comprise a hydrogen gas or other gas. The material may, for example, comprise zeolite. The material is loaded with gas by exposing the material to the gas under high pressure and a cryogenic temperature of about 93 Kelvin or lower. When the material is exposed to gas under pressure and at cryogenic temperature, the gas absorbs into or adsorbs onto the material. The mass of the material is continuously monitored and used to determine when the material is loaded with the desired amount of gas. After the material is loaded with gas, high pressure and cryogenic temperature is maintained while the material is packaged and sealed in a cryogenically cooled container.Type: ApplicationFiled: November 2, 2018Publication date: March 14, 2019Inventors: Darren R. Burgess, Michael Raymond Greenwald, Brent W. Barbee

Publication number: 20180330831Abstract: Reaction processes occurring within an exothermic reaction reactor are investigated by comparing changes to at least one material in the reaction to a non-reacted sample of the material. Prior to the reaction, a sample or “coupon” of the material is removed and retained. The coupon of material is withheld from the reactor. The material is placed in the reactor and at least one exothermic reaction is triggered and sustained. Following the exothermic reaction, the material is removed from the reactor. Both the material and the coupon are then analyzed to ascertain changes to the material that did not occur to the sample. These changes are indicative of processes that occurred in the reactor.Type: ApplicationFiled: December 22, 2016Publication date: November 15, 2018Inventors: Darren R. Burgess, Michael Raymond Greenwald, Brent W. Barbee

Patent number: 10053362Abstract: A gas-loading and packaging system is provided for loading a solid material used in a hydrogen fuel cell with gas and packaging the solid material in a sealed container. The gas may comprise a hydrogen gas or other gas. The solid material may, for example, comprise palladium, a nickel alloy, platinum, or other metal. The solid material is loaded with gas by exposing the solid material to the gas under high pressure. When the solid material is exposed to gas under pressure, the gas absorbs into or adsorbs onto the solid material. The mass of the solid material is continuously monitored and used to determine when the solid material is loaded with the desired amount of gas. After the solid material is loaded with gas, high pressure is maintained while the solid material is packaged in a sealed container that is capable of retaining the high pressure gas.Type: GrantFiled: June 6, 2017Date of Patent: August 21, 2018Assignee: IH IP Holdings LimitedInventors: Darren R.

Patent number: 8322775Abstract: A transparent laminated structure having multiple peel-away laminated film layers for protecting windscreens, particularly windscreens of rotary aircraft, from environmental conditions. The laminated structure includes at least one laminated layer wherein each layer includes a film, a bonding layer on a first major side of the film for releaseably attaching the film to either the windscreen or to an adjacent laminated film layer, a conductive material on a second major side of the film for dissipating electrostatic charging in the laminated structure that may occur due to accumulated precipitation static during aircraft fight, and a hard coat layer for protecting the relatively softer film against abrasion. As the outermost film layer becomes degraded below acceptable levels, that film may be easily removed, exposing a subsequent unblemished film layer.Type: GrantFiled: May 12, 2008Date of Patent: December 4, 2012Assignee: VTOL, LLCInventors: Brent W. Barbee, E. Andrew Hough

The laminated structure includes at least one laminated layer wherein each layer includes a film, a bonding layer on a first major side of the film for releaseably attaching the film to either the windscreen or to an adjacent laminated film layer, optionally a conductive material on a second major side of the film for dissipating electrostatic charging in the laminated structure that may occur due to accumulated precipitation static during aircraft fight, and a hard coat layer for protecting the relatively softer film against abrasion. A keyed removal system is provided simplify determining the number of film layers remaining on the windscreen and to aid in the sequential removal of film layers which become degraded below acceptable levels, thereby exposing a subsequent unblemished film layer.Type: GrantFiled: October 13, 2010Date of Patent: October 23, 2012Assignee: VTOL, LLCInventors: Reginald J.

Publication number: 20100008788Abstract: A protector for the leading edge of a rotor blade to provide enhanced erosion protection thereof. In an embodiment, the protector includes an energy absorption member attached to the rotor blade by a first adhesive bond layer and an erosion resistant member attached to the energy absorption member by a second adhesive bond layer. The erosion resistant member is operative to protect the leading edge of the rotor blade from erosion due to impacts from particulate matter, such as sand and rain. The energy absorption member is operative to absorb and disburse energy from impacts to the erosion protection member so that forces from the impacts are diminished or not transferred to the rotor blade. In another embodiment, the erosion resistant member is coated with a diamond film. As the diamond film is harder than sand, excellent resistance to wear from particulate matter and impacts rain is obtained.Type: ApplicationFiled: July 14, 2009Publication date: January 14, 2010Inventors: Brent W.

Patent number: 6835045Abstract: A protector for protecting aircraft, particularly helicopter rotor blades, from absorbing the sun's infrared rays and the accompanying heat build-up in order to keep adhesive material between spar connections from debonding and to avoid delamination from the rotor blade's composite skin. The rotor blade protector includes a cover configured to encircle the length of the rotor blade and a guide form for installing and removing the cover. The inner surface of the cover is coated, by vacuum deposition technology, with aluminum, titanium, or other metals or alloys. The coating thickness will be in the order of 9-30 billionths of a meter thick. A stripper rod is attached to the guide so that aircraft personnel can install and remove the protector from the helicopter rotor blade while standing on the ground. Optionally, a series of ribs can be provided along the cover to provide increased air insulation around the rotor blade.Type: GrantFiled: May 9, 2003Date of Patent: December 28, 2004Inventors: Brent W.
