Patent number: 9784404Abstract: A method of making a lightweight thermal shield that includes obtaining a mold having a shaped support screen with a molding surface configured to allow the passage of air and moisture therethrough, and with the mold being adapted for drawing a vacuum from behind the support screen. The method also includes applying a wet insulation material onto the molding surface of the support screen and drawing a vacuum to withdraw moisture through the support screen and consolidate a layer of insulation material on top the molding surface. The method further includes removing the consolidated layer of insulation material from off the molding surface, installing the consolidated layer of insulation material into an outer shell layer, and drying the consolidated layer of insulation material within the outer shell layer to form a lightweight core insulation layer.Type: GrantFiled: January 7, 2016Date of Patent: October 10, 2017Assignee: Interface Performance Materials, Inc.Inventors: Brian C.

Patent number: 7278639Abstract: An edge coated gasket includes a base sheet made of compressible gasket material and having opposed faces and an interior edge surrounding and defining an aperture. An edge coating of polymer or other material is disposed on and seals the interior edge of the base sheet and may project beyond the facial planes of the base sheet to define protruding rims extending around the aperture. Face coatings may also be applied to one or more of the faces extending in relatively narrow strips around the aperture of the base sheet. When clamped between flange surfaces, the edge coating engages, conforms to, and seals against the flange surfaces to provide a seal against both interfacial and intersticial migration of fluid past the gasket. At the same time, the inherently good compression failure resistance of the compressible gasket material of the base sheet is preserved. Thus, a gasket with enhanced sealability and compression failure resistance is provided.Type: GrantFiled: March 19, 2003Date of Patent: October 9, 2007Assignee: Interface Solutions, Inc.Inventors: John S. Forry, Brian C. Lehr, Dennis M. Dempsey, Jeffery L. Barrall, Linda L. Sload, Christopher L. Morris

Patent number: 6403180Abstract: An insulating system for pipes is provided which includes at least two different types of pipe insulation, wherein each pipe insulation is a pipe jacket formed by two mating sections, a first section and a second section with each section having a mating surface, wherein further when the two mating sections are put together with the mating surface of the first section exactly abutting the mating surface of the second section, they form a tubular structure having a bore which is a suitable size to receive a pipe. Of the three possible types of pipe insulation available, insulation A, insulation B, and insulation C, each pipe insulation type is formulated to insulate pipes having a different surface temperature, and yet pipe insulations A, B, and C each have identical outer diameters.Type: GrantFiled: May 28, 1998Date of Patent: June 11, 2002Assignee: Armacell Enterprises GmbHInventor: Jeffery L.

Patent number: 5415824Abstract: A pipe cladding composition which is a phosphate ceramic permeating a non-woven fibrous network. The overall thickness of the sheet is between about 5 and about 20 mils. The phosphate ceramic permeates the fibrous network and extends beyond the fibrous network only up to a maximum thickness of about 3 mils across each side of the sheet. The sheets are prepared using wet reaction mixtures which produce phosphate ceramics. These reaction mixtures are mixed and pressed into the non-woven fibrous network which forms a wet sheet that is then cured to provide the cladding material.Type: GrantFiled: January 27, 1994Date of Patent: May 16, 1995Assignee: Armstrong World Industries, Inc.Inventors: Jeffery L.

Patent number: 5225380Abstract: Calcium aluminum magnesium phosphate ceramic hard tiles and processes for them are described. The tiles have a density in excess of about 110 pounds per cubic foot, a curl value less than about 20 mils and a flexural strength of at least about 2500 pounds per square inch. To prepare the hard tiles 100 parts (by wt.) of an aluminum phosphate-phosphoric acid solution is mixed with at least 5 parts magnesium oxide and 50-110 parts wollastonite. If the acid has more than 15% by weight water, then mica or vermiculite is added.Type: GrantFiled: December 23, 1991Date of Patent: July 6, 1993Assignee: Armstrong World Industries, Inc.Inventors: Jeffery L.
