Patent number: 8511970Abstract: A plug assembly is disclosed herein for a borescope inspection path defined through apertures in spaced walls. The plug assembly includes a first plug operable to at least partially close a first aperture in an inner wall. The plug assembly also includes a second plug operable to at least partially close a second aperture in an outer wall. The plug assembly also includes a member extending along an axis and connecting the first and second plugs together in spaced relation to one another along the axis. The member is operable to elastically buckle.Type: GrantFiled: September 30, 2009Date of Patent: August 20, 2013Assignee: Rolls-Royce CorporationInventors: Nathan Wesley Ottow, Vance A. Mahan, Denise C. Tommasone

Patent number: 7784528Abstract: A heat exchanger system includes a duct having a duct wall with a duct wall outer surface and a duct wall inner surface; and a heat exchanger partial shell hermetically joined to the duct wall inner surface. The heat exchanger partial shell and a shell portion of the duct wall inner surface constitute a heat exchanger. A heat exchanger inlet manifold is defined by a nonplanar inlet sheet of material hermetically joined to the duct wall outer surface. A heat exchanger outlet manifold is defined by a nonplanar outlet sheet of material hermetically joined to the duct wall outer surface. A heat exchanger inlet opening extends through the duct wall between the inlet manifold and the heat exchanger, and a heat exchanger outlet opening extends through the duct wall between the outlet manifold and the heat exchanger.Type: GrantFiled: December 27, 2006Date of Patent: August 31, 2010Assignee: General Electric CompanyInventors: Nathan Wesley Ottow, Scott Richard Zearbaugh, Phillip Michael Lariviere
