Patent number: 11904349Abstract: A spray application system and a method of its operation are provided for applying a spray treatment onto a surface of an airframe of an aircraft. The spray application system includes a set of multiple modular hood units that are combinable to form a combined enclosure that defines a shared interior volume. Each modular hood unit of the set includes one or more enclosure walls. At least two airframe-interfacing edges of each modular hood unit define a portion of a spray treatment region of the airframe. At least one inter-unit-interfacing edge of each modular hood unit is configured to interface with another inter-unit-interfacing edge of a neighboring modular hood unit of the set to form at least a portion of the combined enclosure. A spray access port is defined within an enclosure wall of each modular hood unit.Type: GrantFiled: November 12, 2022Date of Patent: February 20, 2024Assignee: The Boeing CompanyInventors: Yu-Chin Jou, Brian R. Conlan, Thi Q. Nguyen, Jeffrey T. Tan, Ryan Walter Throckmorton, Eli Samuel Horden, Arturo Trejo

Patent number: 11896954Abstract: The present invention relates to a process for the manufacture of microporous carbon materials to perform selective separations of nitrogen in gas mixtures such as hydrogen sulfide, carbon dioxide, methane and C2, C3 and C4+ hydrocarbons, with high efficiency, shaped of microspheres or cylinders from copolymers of poly (vinylidene chloride-co-methyl acrylate) with density of 1.3 to 1.85 g/cm3 or poly (vinylidene chloride-co-vinyl chloride) with density of 1.3 to 1.85 g/cm3, using two stages. The first stage consists of a surface passivation of the material by chemical attack in a highly alkaline alcohol solution, with the aim of effecting a precarbonization on the surface of the copolymer that during the pyrolysis process is not deformed and gradually develops microporosity. The material of the first stage presents, in the layer, percentages between 55% to 85% carbon, between 5% to 20% oxygen, and between 10% to 40% chlorine.Type: GrantFiled: June 17, 2021Date of Patent: February 13, 2024Assignee: INSTITUTO MEXICANO DEL PETROLEOInventors: Federico Jesus Jimenez Cruz, Jose Luis Garcia Gutierrez, Jose Francisco Gaspar Silva Sanchez, Liliana Alejandra Astudillo Lopez Lena, Fidencio Hernandez Perez, Alberto Cabrales Torres, Maria Del Carmen Martinez Guerrero, Marco Antonio Dominguez Aguilar, Arturo Trejo Rodriguez, Florentino Rafael Murrieta Guevara

Publication number: 20110041600Abstract: A fuel level sensor includes a wiper support with metal wiper contacts. A rotatable shaft holds the wiper support and a seal assembly is provided in which the wiper support is disposed. The seal assembly includes a frame and a cover that are sealed together along respective peripheries with the wiper support being sandwiched therebetween. The shaft extends into and through an opening formed in the cover and is rotatable therein with a holder covering an end of the shaft and sealing the opening in cooperation with the cover. The frame is formed with a diaphragm above the wiper shaft that is deflectable to facilitate assembly and allow the sensor to compensate for pressure changes in a fluid tank in which the sensor can be disposed.Type: ApplicationFiled: August 19, 2009Publication date: February 24, 2011Applicant: DELPHI TECHNOLOGIES, INC.Inventors: Luis M.
