Publication number: 20120248661Abstract: A polymeric composition composed of a polymeric material and at least one additive. The polymeric material is at least one of a polymeric precursor material or a melt processible polymeric material. The additive is complexed with the polymeric material and is an inorganic or organo-inorganic complex that is integrated into at least a portion of the polymeric chains in the polymeric composition. The additive may be at least one of oxide glass compounds or halogenated post-transition metal compounds and is present in an amount sufficient to increase the material weight without unduly compromising optical qualities such as transparency to visible light. The polymeric composition can be provided in melt processible form to be used to produce articles such as drinking glasses and the like. The composition can be produced by processes such as dispersion by polymerization of the monomers producing the desired polymeric material in the presence of the additive.Type: ApplicationFiled: April 4, 2012Publication date: October 4, 2012Applicant: WASBBB, INC.Inventor: Ralph Locke

Patent number: 8231824Abstract: A method and an apparatus for producing an endless double-walled pipe having corrugated pipe sections and sleeve pipe sections are described. The production is effected by extrusion of an outer tube (Sa), forming the outer pipe of the double-walled pipe, and of an inner tube (Si), forming the inner tube of the double-walled pipe, in a molding passage (10) having sections with a corrugated molding surface and a smooth cylindrical sleeve molding surface. To shape the sleeve section, the outer tube is extruded into the sleeve molding surface and is brought into contact with the sleeve molding surface. The inner tube (Si) is then extruded into the outer tube (Sa), already in contact over the entire axial length of the sleeve molding surface, and is brought in the process into contact with the inner side of said outer tube (Sa) that is in contact.Type: GrantFiled: October 18, 2008Date of Patent: July 31, 2012Assignee: Unicor GmbHInventor: Hubert Kossner
