Sintered shaped body, whose surface comprises a porous layer and a method for the production thereof
Patent number: 7074479Abstract: Porous coatings on high-performance ceramics attempt to combine the mechanical and thermal characteristics, which fulfil stringent demands, of the substrate material with the advantageous properties of coating materials. The subsequent application of layers of this type to the pre-sintered substrate produces unsatisfactory results in several areas of use with regard to possible layer thickness, porosity and adhesion. According to the invention, a shaped body consisting of a sintered, inorganic material, whose surface comprises a porous layer is produced in such a way that the base body is first formed as a green body. A layer in the form of a suspension, also containing an inorganic material, is then applied to the surface or to one section of the surface of the base body. A predetermined fraction of a pore-forming substance is mixed with at least the material of said layer and the green body with its applied layer is subjected to the thermal treatments required for producing a monolithic sintered body.Type: GrantFiled: March 14, 2001Date of Patent: July 11, 2006Assignee: Ceramtec AG Innovative Ceramic EngineeringInventors: Dirk Rogowski, Hans-Georg Pfaff, Alwin Nagel -

Patent number: 7008691Abstract: The present invention relates to a process of forming a multi-layer pad of a non-woven fiber batt and a foam layer having conforming convoluted surfaces and to a multi-layer pad incorporating a non-woven fiber batt and foam layer. The process of forming a non-woven batt layer and a foam layer having conforming convoluted surfaces comprises transporting each layer along its longitudinal dimension while compressing each layer along its lateral dimension. Concomitantly with compression, each layer is cut transversely along its lateral dimension to separate each layer into an upper segment and a lower segment and to provide conforming convoluted surfaces on the segments of each layer, the convoluted surfaces comprised of upstanding projections and depressions.Type: GrantFiled: May 27, 2003Date of Patent: March 7, 2006Assignee: L&P Property Management CompanyInventor: Steven Eugene Ogle

Patent number: 7001656Abstract: The invention relates to a rigid multilayer material for thermal insulation, in particular in a vacuum, the material comprising at least one insulating plate of honeycomb material sandwiched between two aluminum- or gold-coated skins of low emissivity. In order to optimize thermal insulation, the diameter of the cells is at least twice their height. The multilayer material may have as many layers as needed. The cells of adjacent layers may be offset in order to further minimize paths for heat conduction through the structure. Holes may be pierced in the side walls of the cells in order to allow them to empty out when the material is put into a vacuum. The invention also provides a method of making such a material.Type: GrantFiled: April 23, 2003Date of Patent: February 21, 2006Assignee: AlcatelInventors: Michel Maignan, Thierry Youssefi, Bertrand Brevart

Patent number: 6991847Abstract: The invention relates to processes for the synthesis of 2-D and 3-D periodic porous silicon structures and composites with improved properties having the advantages of porous silicon and photonic bandgap materials. Photonic crystals comprise a two dimensionally periodic or three dimensionally periodic microporous structural matrix of interconnecting, crystallographically oriented, monodispersed members having voids between adjacent members, and said members additionally having randomly nanoporous surface porosity. The silicon nanofoam material shows enhanced and spectrally controlled/tunable photoluminescence and electroluminesce and finds use as transparent electrodes, high-lumonosity light emitting diodes (LEDs), wavelength division multiplexors, high-active-area catalyst supports, photonic bandgap lasers, silicon-based UV detectors, displays, gas sensors, and the like.Type: GrantFiled: February 7, 2002Date of Patent: January 31, 2006Assignee: Honeywell International Inc.Inventors: Aravind Padmanabhan, Ray H. Baughman, Anvar A. Zakhidov, Guenadiy Lazarov

Patent number: RE39761Abstract: A laminate wall structure which can be used as an exterior wall in manufactured housing and site built construction is made up of a low density layer having a density of from about one-half pound to three pounds per cubic foot, a second, reinforcing layer laminated to the low density layer and, optionally, a cellulosic layer laminated to the second, reinforcing layer. The low density layer is preferably a foamed polymer layer, the second, reinforcing layer is a polymer fabric, a biaxially oriented polymeric film or a fiberglass reinforced material and the cellulosic layer can be impregnated with an adhesive and/or resin in order to strengthen the laminate structure. This laminate wall structure has a low weight and yet is strong enough to meet wind zone wall diaphragm requirements for housing construction.Type: GrantFiled: July 23, 2004Date of Patent: August 7, 2007Assignee: National Shelter Products, Inc.Inventor: John Cahill
