Patent number: 8066852Abstract: Light hydrocarbon enrichment is accomplished using a vertically oriented distillation column having a plurality of vertically oriented, nonselective micro/mesoporous hollow fibers. Vapor having, for example, both propylene and propane is sent upward through the distillation column in between the hollow fibers. Vapor exits neat the top of the column and is condensed to form a liquid phase that is directed back downward through the lumen of the hollow fibers. As vapor continues to ascend and liquid continues to countercurrently descend, the liquid at the bottom of the column becomes enriched in a higher boiling point, light hydrocarbon (propane, for example) and the vapor at the top becomes enriched in a lower boiling point light hydrocarbon (propylene, for example). The hollow fiber becomes wetted with liquid during the process.Type: GrantFiled: June 30, 2010Date of Patent: November 29, 2011Assignee: Los Alamos National Security, LLCInventors: Dali Yang, David Devlin, Robert S. Barbero, Martin E. Carrera, Craig W. Colling

Patent number: 7022165Abstract: A tubular hydrogen permeable metal membrane and fabrication process comprises obtaining a metal alloy foil having two surfaces, coating the surfaces with a metal or metal alloy catalytic layer to produce a hydrogen permeable metal membrane, sizing the membrane into a sheet with two long edges, wrapping the membrane around an elongated expandable rod with the two long edges aligned and overlapping to facilitate welding of the two together, placing the foil wrapped rod into a surrounding fixture housing with the two aligned and overlapping foil edges accessible through an elongated aperture in the surrounding fixture housing, expanding the elongated expandable rod within the surrounding fixture housing to tighten the foil about the expanded rod, welding the two long overlapping foil edges to one another generating a tubular membrane, and removing the tubular membrane from within the surrounding fixture housing and the expandable rod from with the tubular membrane.Type: GrantFiled: August 29, 2003Date of Patent: April 4, 2006Assignee: The Regents of the University of CaliforniaInventors: Stephen N. Paglieri, Stephen A. Birdsell, Robert S. Barbero, Ronny C. Snow, Frank M. Smith

Patent number: 5981827Abstract: A composite article is disclosed including a porous structural member formed of carbon fiber, the porous structural member containing a multiplicity of pores of dimensions greater than about 200 microns in diameter, the porous structural member further including carbon fill material within a portion of the pores such that the pores are essentially less than about 200 microns in diameter, the porous structural member including carbon fill material defining a composite carbon/carbon intermediate article including an outer surface and a thin coating of diamond-like carbon upon the outer surface of the composite carbon/carbon intermediate article. The composite article may serve as a prosthetic device for replacement joints, bone structures and the like.Type: GrantFiled: November 12, 1997Date of Patent: November 9, 1999Assignee: Regents of the University of CaliforniaInventors: David J. Devlin, David W. Carroll, John G. Cowie, Robert S. Barbero
