Publication number: 20080134884Abstract: A gas separator, a method for producing the gas separator, and a method for separating gases based on a property of inelasticity of the gases. The inventive gas separator is a permeable porous material for separating a mixture of gases by selectable pore size exclusion, comprising pores formed with at least one nanostructured compound. In other words, the inventive porous material can be used to separate a mixture of gases based upon the different working diameter of each of the gases. By selecting specific nanostructured compounds, the porous material can be tailored to contain pores of a predetermined size which allow gases having a working diameter smaller than the size of the pores to pass through the material while preventing the passage of gases having a working diameter greater than the size of the pores.Type: ApplicationFiled: October 31, 2007Publication date: June 12, 2008Inventors: Jack Sammons, David M. Goddard

Patent number: 4831707Abstract: Glass or ceramic fibers or other fibers such as graphite properly protected by a suitable adherent ceramic or metal coating are immersed in a liquid metallo-organic solution containing a noble metal compound as a primary ingredient, then dried and fired in air or in a slightly oxidizing atmosphere so as to produce a noble metal coating on the fibers. Fibers may be in the form of individual filaments, as a multifilament tow or yarn or as a woven fabric. The fibers coated with a nobel metal are then incorporated into a metal matrix composite material by immersion in a molten bath of the desired matrix metal, placing the fibers in a suitable mold and casting the molten matrix metal around them or placing the fibers between solid sheets of matrix metal and effecting consolidation by diffusion bonding. The coating thickness on the fibers should be at least 0.30 microns and should not exceed 0.50 microns.Type: GrantFiled: January 13, 1984Date of Patent: May 23, 1989Assignee: Fiber Materials, Inc.Inventors: David M. Goddard, Richard W. Sexton

Patent number: 4341823Abstract: The present invention comprises a process of preparing metal matrix composites which are reinforced by ceramic or graphite fibers, wherein the fibers are pretreated; first by a nickel coating, then by a second coating which is sacrificed when the fibers are ultimately immersed in a liquid metallic bath which becomes the matrix of the composite material formed. Usually the second coating is copper.In addition, a third coating on the fibers comprising a noble metal such as silver may also be used for certain matrix metal materials. Preferably the thickness of the nickel coating is a minimum of 0.5 micrometers and the second sacrificial coating is a minimum of 0.5 micrometers. After the fibers have been coated with the two or more successive coatings, they are incorporated into a metal matrix composite material by immersion in a molten bath of the desired matrix metal, or by placing the fibers in a suitable mold and casting the molten metal matrix around them, or by other suitable means.Type: GrantFiled: January 14, 1981Date of Patent: July 27, 1982Assignee: Material Concepts, Inc.Inventors: Richard W.
