Patent number: 8851125Abstract: An intermediate insulating product (20) is disclosed comprising a planar insulating layer (11) having a top side in to which is formed a plurality of parallel channels (14) having cross-sections with tapered sides. A vapor proof layer (18) is applied to the top surface after the channels (14) have been formed such that the vapor proof layer (18) bridges the plurality of parallel channels (14). The intermediate insulating product (20) is then bent with mechanical manipulation in regions adjacent the bottom of the channels (14) thereby causing the channels (14) to close to form a non-planar, derivative insulated ductwork product (30) and the vapor proof layer (18) forms a vapor proof inner lining to the derivative insulated ductwork product (30).Type: GrantFiled: September 28, 2007Date of Patent: October 7, 2014Assignee: Spiralite Holdings LimitedInventors: Peter Dudley, Peter Merrien, Kevin Sewell

Publication number: 20140290783Abstract: An HVAC duct is provided. The duct includes an outer tube having a fully continuous external perimeter. The duct further includes an inner tube capable of conveying forced air. The inner tube extends within the outer tube longitudinally. The duct also includes a plurality of support elements spanning between the outer tube and the inner tube. The elements extends along the outer tube and the inner tube longitudinally. The elements define a plurality of channels between the outer tube and the inner tube. The outer tube, the inner tube, and the elements are fully unitary.Type: ApplicationFiled: January 13, 2014Publication date: October 2, 2014Inventor: Carl Fanelli

Publication number: 20140283941Abstract: A seamless self-insulated foam duct made from a single continuous homogenous member of polymeric foam and an apparatus and methods for making such ducts. The homogenous foam member may be transformed to include a plurality of layers such as a densified inner foam layer surrounded by an outer insulating foam layer. The outer insulating foam layer may be partially densified to form a densified outer foam layer. In one embodiment the foam member may be wrapped and bonded to an external layer coating that provides additional protection to the duct. In one embodiment the foam duct is modified to have nestable ends whereby one end of a first foam duct is sized and shape to fit within and snugly engage a compatible end of a second foam duct. The duct may be manufactured by an apparatus capable of implementing a series of cutting and densifying steps that result in custom-sized foam ducts having one or more densified foam layers.Type: ApplicationFiled: March 25, 2013Publication date: September 25, 2014Applicant: Evonik Foams, Inc.Inventors: Steven R. Bailey, Sharon White Ferguson

Patent number: 8789562Abstract: Provided is a flexible tube which is used to load fluid from a floating facility on the sea onto a tanker, which is suitable for transport of cryogenic fluid such as LNG, and which is capable of quickly and reliably detecting leakage of the fluid in the tube. Also provided is a structure for detecting leakage of fluid in a tube. A water impermeable and heat insulating layer is provided on the outer periphery of a heat insulating layer. The water impermeable and heat insulating layer, together with the heat insulating layer, thermally insulates LNG flowing through a corrugated tube from the outside of a flexible tube. Unlike the heat insulating layer, the water impermeable and heat insulating layer is poor in liquid permeability, and fluid such as LNG hardly permeates the water impermeable and heat insulating layer. That is, the water impermeable and heat insulating layer serves as a water impermeable layer between the inside and outside of the water impermeable and heat insulating layer.Type: GrantFiled: March 9, 2009Date of Patent: July 29, 2014Assignees: Furukawa Electric Co., Ltd, Japan Oil, Gas and Metals National CorporationInventor: Toru Kagoura
