Patent number: 11035501Abstract: A flexible air duct contains a uniformly-spaced reflective insulation system, with or without bulk insulation, a liner, and an outer jacket that would allow a reduced amount or no amount of bulk insulation to be used to obtain a desired R-value insulation. The flexible air duct can be used to move conditioned air to one or more desired locations.Type: GrantFiled: June 4, 2019Date of Patent: June 15, 2021Assignee: FLEXIBLE TECHNOLOGIES, INC.Inventors: Ronald L. Carlay, II, John Cullen Schlageter, Donald B. Campbell

Patent number: 10767892Abstract: A flexible duct for handling conditioned air comprises an inner core, a vapor barrier, and a compressible core spacer positioned between the inner core and vapor barrier. The compressible core spacer is made of a film material with a helical support integrated therewith. The compressible core spacer is made of a length longer that the inner core and other duct components so that when the compressible core spacer is compressed when assembling the inner core and vapor barrier, the film material between adjacent sections of the helical support folds to create a spacer-liker construction that creates air gaps between an outer surface of the inner core and an inner surface of the compressible core spacer and outer surface of the inner core and vapor barrier. With a pair of low-e surfaces associated with the compressible core spacer or the compressible core spacer and inner core, reflective insulation systems are created to improve the insulating value of the insulated flexible duct.Type: GrantFiled: November 27, 2018Date of Patent: September 8, 2020Assignee: FLEXIBLE TECHNOLOGIES, INC.Inventors: Donald B. Campbell, Ronald L. Carlay, II

Patent number: 10295218Abstract: An insulated duct comprises a free floating liner, an optional bulk insulation layer, a vapor barrier, and a reflective insulation system. The reflective insulation system includes an air gap and a low-e surface. The gap is positioned between the bulk insulation layer and the low-e surface or the outer member and the low-e surface if no insulation is used to gain additional insulating value for the duct. With the free floating liner and the reflective insulation system, a duct can be made to an industry standard R-value while using bulk insulation with a lower R-value.Type: GrantFiled: August 8, 2016Date of Patent: May 21, 2019Assignee: FLEXIBLE TECHNOLOGIES, INC.Inventors: Donald B. Campbell, Ronald L. Carlay, II

Patent number: 5111872Abstract: A novel cover (10) for one end of the casing within which a vehicular transmission is housed and a unique method for making the cover. The cover (10) has a metallic body portion (12) within which a unitary manifold (40) has been cast in situ. The manifold (40) incorporates a plurality of conduits having artight mechanically crimped ends (A-E) which have been preformed and conjoined into the unitary manifold (40) that is precisely disposed within a mold. Molten metal is admitted into the mold to encapsulate the manifold (40) within the metallic body portion (12) of the cover (10). After the cover (10) has been cast, with the manifold (40) encapsulated therein, the cover (10) is removed from the mold, and only a relatively modest amount of machining operations are required to complete the cover (10).Type: GrantFiled: July 8, 1991Date of Patent: May 12, 1992Assignee: Saturn CorporationInventors: Rodney A. Diehl, Robert L. Uhrman, Jr., Robert G. Bishop, Donald B. Campbell
