Patent number: 10076895Abstract: A multifunctional fully integral panel system design, a unique material configuration, and a process for fabricating a net shape (or nearly net shape) panel in one production cycle. The panel may comprise a base facing with an outer perimeter, a decorative film applied to the exterior of the base facing, an aft facing having an outer perimeter fused to the base facing, and a reinforcement core disposed between the unfused portions of the base and aft facings, which reinforcement core also acts as acoustic insulation (i.e., a noise attenuator). Alternatively or additionally, a foam core or blanket having thermal and/or acoustic insulation properties is attached to the external surface of the aft facing. The fabrication process involves the application of different heat treatments to panel components having different forming temperature or rubbery/elastic plateaus.Type: GrantFiled: March 4, 2015Date of Patent: September 18, 2018Assignee: The Boeing CompanyInventors: Jayant Dahyabhai Patel, John N. Harris, Sergio H. Sanchez, James A. Fullerton

Patent number: 8061477Abstract: Apparatus and methods described herein provide for the management of noise associated with a duct. A sound-dampening apparatus is provided consisting of a duct through which a fluid flows, such as an air duct. A flexuous cord is helically wound around the inner or outer surface of the duct at a pitch corresponding to a selected acoustical frequency range associated with the fluid flow through the duct.Type: GrantFiled: August 20, 2008Date of Patent: November 22, 2011Assignee: The Boeing CompanyInventors: Jayant Dahyabhai Patel, W. Forrest Frantz, Douglas Dean Maben, Clifford John Petersen, David V. Algas

Patent number: 7083147Abstract: Modularized insulation blanket for thermal and/or acoustical insulation. The modularized insulation blanket has a cover formed of a distal layer and proximal layer in sealed mated relationship. The distal and proximal layers are sealed along longitudinal and latitudinal heat-sealed seams that define a plurality of modules. The heat-sealed seam may be creased so as to be foldable and/or perforated to provide a tear line. Within the modules are batting blocks. The blankets may be attached to surface structures such as the interior skin surface of an aircraft fuselage, pipes or other structures with retention systems. The blankets may be formed in an apparatus including a platen, heat seal rollers or heating sealing mechanisms, and edge sealers.Type: GrantFiled: March 11, 2004Date of Patent: August 1, 2006Assignee: The Boeing CompanyInventors: Sami Movsesian, Jayant Dahyabhai Patel, Ted Workman, Marc A.

Patent number: 6145895Abstract: A sleeve for coupling together two fluid-handling conduits includes a compressible and resilient tubular core and a protective fabric cover which covers at least portions of the outer surface of the core and is substantially inexpansible in the radial and circumferential directions so as to resist radial and circumferential expansion of the core. The core is preferably a cellular elastomeric foam and the fabric cover advantageously is integrally molded into the core. The core is sized slightly smaller in diameter than the conduits to be joined so that it is expanded radially when installed onto a conduit. Expansion of the core is resisted by the fabric cover, and thus the core is radially compressed and provides a continuous restoring force urging the sleeve against the conduit.Type: GrantFiled: December 30, 1998Date of Patent: November 14, 2000Assignee: The Boeing CompanyInventors: Jayant Dahyabhai Patel, Clifford John Petersen, Ronald Joseph Talamantez

Patent number: 5836048Abstract: The larger of the two flanges in a grommet contains a tip portion that extends back toward the other tapered flange and overlies the circumferential slot between the two flanges to define a grommet having application to panels of a variety of thicknesses. The tip portion elastically bends, upon installing the grommet in a panel, responsive to force exerted by a side wall of the panel. It exerts an elastic reaction force pressing on a side of the panel. Concurrently it pulls the other tapered flange into contact with the opposed surface of the panel through elastic force exerted through the grommets midsection. This seals the flanges against the panel's sides, notwithstanding a circumferential slot width greater than the panel's thickness and notwithstanding a panel mounting hole having a greater diameter than the bottom surface of that slot. A fire resistant layer is integrally formed or applied in that outer surface of the grommet containing the larger flange.Type: GrantFiled: August 9, 1996Date of Patent: November 17, 1998Assignee: McDonnell Douglas CorporationInventors: John Alfred Rossman, Jayant Dahyabhai Patel
