Patent number: 6342280Abstract: The present invention relates to a method for improving both adhesion between substrate and polymer layers and the durability of such composite structures; while maintaining the malleability and preferred characteristics of the original substrate. Quite unexpectedly, the application of a layer or film upon an uncured, encapsulated base substrate which has been encapsulated by the shear thinning methods of the present invention, results in superior adhesion of multiple layers when compared to conventional layering, coating or composite manufacturing methods. Moreover, the uncured or at most, semi-cured, polymer composition applied to the base substrate ensures that the substrate maintains maximum flexibility for subsequent shaping into composite articles prior to curing. The methods described herein produce multiple layer composite articles that are lighter, stronger, more flexible and utilize less material, than composite articles produced by conventional techniques.Type: GrantFiled: June 23, 1998Date of Patent: January 29, 2002Assignee: Nextec Applications, Inc.Inventors: Rodney Lane Patrick, James Michael Caldwell, Peter Uwe Mekailian

Patent number: 6335065Abstract: A process for centrifugal slip casting a textured hollow tube. A slip made up of a carrier fluid and a suspended powder is introduced into a porous mold which is rotated at a speed sufficient to create a centrifugal force that forces the slip radially outward toward the inner surface of the mold. The suspended powder, which is formed of particles having large dimensional aspect ratios such as particles of superconductive BSCCO, settles in a textured fashion radially outward toward the mold surface. The carrier fluid of the slip passes by capillary action radially outward around the settled particles and into the absorbent mold. A layer of mold release material is preferably centrifugally slip cast to cover the mold inner surface prior to the introduction of the BSCCO slip, and the mold release layer facilitates removal of the BSCCO greenbody from the mold without fracturing.Type: GrantFiled: November 10, 1999Date of Patent: January 1, 2002Assignee: Purdue Research FoundationInventors: Greg A. Steinlage, Kevin P. Trumble, Keith J. Bowman

Publication number: 20010048985Abstract: Fire and heat protective containers having two matable portions, the outer walls of which are formed as hollow shells filled with a ceramic gel material containing at least water glass and a polyvalent metal salt, preferably calcium chloride. For ensuring that stored articles are not exposed to temperatures greater than 125 degrees F., a layer of low-density, expended or foamed plastic insulation and a layer of phase change material are provided within the gel layer. A preferred phase change material is a mixture of water glass and a hydrated salt, preferably sodium phosphate, having a melting point around 120 degrees F. and a heat of fusion of at least 250 joules per gram. The phase change material is also contained in hollow shells, the walls of both the outer and inner shells being molded plastic parts.Type: ApplicationFiled: May 21, 2001Publication date: December 6, 2001Applicant: Fireking International, Inc.Inventor: David J.

Publication number: 20010048984Abstract: The present invention contemplates water-bearing silicate materials for fire protection which are essentially dry when cured. The dryness property is achieved by modifying the basic method of essentially reacting water glass with calcium chloride in such a way as to bind the free water into solid form without adversely affecting the basic chemical and physical structure of the original product. The invention further contemplates the incorporation of these materials into one or more fire protection container configurations such as a multilayered structure in which the insulation forms the outermost wall of the container, an intermediate layer comprising a light weight porous, thermal insulator such as urethane foam, and an innermost layer comprising a phase change material with a melting point of around 70 degrees F. to 125 degrees F., depending on the heat bearing characteristics of the objects to be protected.Type: ApplicationFiled: January 12, 2001Publication date: December 6, 2001Inventor: David J.

Patent number: 6316383Abstract: Moldings based on silica having a hollow cylindrical configuration with internal reinforcing stays or spokes leading from an inner wall of a hollow cylinder to the center of the molding or in the form of miniliths having passageway channels therethrough, are produced by homogenizing silica with methyl hydroxyethyl cellulose, wax and/or polyethylene glycol. Water and optionally aqueous alkaline ammonia solution are added, and the mixture is subjected to kneading and forming, extruding, optionally cutting the extrudate to the desired length by means of a cutting device, drying at a temperature from 20 to 150° C., and annealing for a period from 30 minutes to 10 hours at a temperature of 400 to 1200° C. The moldings can be used as catalyst supports for the production of unsaturated esters from olefins, organic acids and oxygen in the gas phase and and can be used in particular for the production of vinyl acetate monomer.Type: GrantFiled: June 25, 1999Date of Patent: November 13, 2001Assignee: Degussa AGInventors: Thomas Tacke, Peter Schinke, Hermanus Lansink Rotgerink, Helmfried Kraus
