Patent number: 9869412Abstract: A pipe including an inner layer, an outer layer, a jacket layer, and an anisotropic layer positioned between the jacket and outer layers is provided. The anisotropic layer is formed from weaving a number of more rigid, monofilament fill strands and a number of less rigid multifilament warp strands. The fill strands may be formed from single, six hundred-ten (610) denier polyester filament while the warp strands may be formed from a series of two hundred-twenty (220) denier polyester threads. The anisotropic layer permits limited rotation of the inner and outer pipe layers without inserting into the gaps formed by the jacket layer when exposed to intense heat and pressure and is not subjected to significant creep during use.Type: GrantFiled: April 27, 2017Date of Patent: January 16, 2018Assignee: HIGHLAND INDUSTRIES, INC.Inventor: James Rollings Newsome

Patent number: 9849405Abstract: Methods of making thermal insulation products that may be usable to provide insulation in high temperature applications. One method includes sealing a support material (e.g., a nanoporous core such as fumed silica, an aerogel powder, etc.) and at least one vapor within an interior portion of a substantially gas-impermeable envelope (e.g., a metallic and/or polymeric film), and then condensing at least a portion of the vapor after the sealing step to reduce the pressure within the gas-impermeable envelope from a first pressure before the condensing to a lower second pressure after the condensing. The disclosed methods limit or eliminate the need for pumping mechanisms to draw the vacuum within the products, drying of the core before the sealing, and the like.Type: GrantFiled: January 14, 2014Date of Patent: December 26, 2017Assignee: Nanopore, Inc.Inventor: Douglas M.

Patent number: 9851126Abstract: A cooling apparatus having a closed cooling circuit for cooling objects to semi-cryogenic or cryogenic temperatures includes a compressor to compress a gaseous coolant, and from which the coolant exits in a compressed gaseous state, an after-cooler connected downstream from the compressor, whereby the coolant exits largely in gaseous form, a counterflow heat exchanger having a feed line and return line arranged in such a way that the compressed coolant is liquefied in the feed line as the relieved coolant flowing through the return line is being heated. A cooling head that is connected with the feed line and return line. A coolant can flow through the cooling head whereby the coolant evaporates. The cooling head is arranged in a vacuum chamber, which can be joined with a low-pressure source, and is joined by flexible connecting lines with the feed line and return line of the counterflow heat exchanger.Type: GrantFiled: July 12, 2011Date of Patent: December 26, 2017Assignee: Johannes WildInventor: Johannes Wild

Patent number: 9845727Abstract: A non-metallic tailcone (202) in a tip turbine engine includes a tapered wall structure disposed (208) about a central axis. The non-metallic tailcone is fastened to a structural frame (44) in the aft portion of the tip turbine engine. The tip turbine engine produces a first temperature gas stream from a first output source and a second temperature gas stream from a second output source. The second temperature gas stream is a lower temperature than the first temperature gas stream. The second temperature gas stream is discharged at an inner diameter of the tip turbine engine over an outer surface of the tailcone. Discharging the cooler second temperature gas stream at the inner diameter allows a non-metallic to be used to form the tailcone.Type: GrantFiled: December 1, 2004Date of Patent: December 19, 2017Assignee: United Technologies CorporationInventors: Gabriel L. Suciu, James W. Norris, Brian Merry

Patent number: 9776693Abstract: Systems and methods for adding buoyancy to an object are described herein. A buoyant material may be enclosed inside a flexible container, heated, and inserted into a free flooded cavity inside the object. The flexible container may then be formed to the shape of the cavity. After the flexible container is formed to the shape of the cavity, the flexible container may be cooled. The flexible container may hold a pre-determined amount of the syntactic material that provides a fixed amount of buoyancy. According to another aspect, systems and methods for packing a vehicle are described herein. In some embodiments, a buoyant material may be molded into the shape of a hull of a vehicle, and a plurality of cutouts may be extracted from the buoyant material which are specifically designed to incorporate one or more instruments.Type: GrantFiled: March 13, 2014Date of Patent: October 3, 2017Assignee: HADAL, INC.Inventors: Richard J.
