Patent number: 8440302Abstract: A reinforced carbon foam material is formed from carbon fibers incorporated within a carbon foam's structure. First, carbon fiber bundles are combined with a liquid resol resin. The carbon fiber bundles separate into individual carbon fiber filaments and disperse throughout the liquid resol resin. Second, the carbon fiber resin mixture is foamed thus fixing the carbon fibers in a permanent spatial arrangement within the phenolic foam. The foam is then carbonized to create a carbon fiber reinforced foam with improved graphitic characteristics as well as increased strength. Optionally, various additives can be introduced simultaneously with the addition of the carbon fiber bundles into the liquid resol, which can improve the graphitic nature of the final carbon foam material and/or increase the foam's resistance to oxidation.Type: GrantFiled: June 8, 2010Date of Patent: May 14, 2013Assignee: GrafTech International Holdings Inc.Inventors: Douglas J. Miller, Irwin C. Lewis, Richard L. Shao, Mehmet Suha Yazici

Patent number: 6607586Abstract: An apparatus for removing particles from air, including an inlet for receiving a flow of air, a first chamber in flow communication with the inlet, wherein a charged spray of semi-conducting fluid droplets having a first polarity is introduced to the air flow so that the particles are electrostatically attracted to and retained by the spray droplets, and an outlet in flow communication with the first chamber, wherein the air flow exits the apparatus substantially free of the particles. The first chamber of the apparatus further includes a collecting surface for attracting the spray droplets, a power supply, and a spray nozzle connected to the power supply for receiving fluid and producing the spray droplets therefrom. The apparatus may also include a second chamber in flow communication with the inlet at a first end and the first chamber at a second end, wherein particles entrained in the air flow are charged with a second polarity opposite the first polarity prior to the air flow entering the first chamber.Type: GrantFiled: October 29, 2001Date of Patent: August 19, 2003Assignee: The Procter & Gamble CompanyInventors: Alan David Willey, Vladimir Gartstein, Marta Lea Verhoff, Mehmet Suha Yazici
