  • Patent number: 6833011
    Abstract: An ablation resistant, monolithic, activated, carbon foam produced by the activation of a coal-based carbon foam through the action of carbon dioxide, ozone or some similar oxidative agent that pits and/or partially oxidizes the carbon foam skeleton, thereby significantly increasing its overall surface area and concurrently increasing its filtering ability. Such activated carbon foams are suitable for application in virtually all areas where particulate or gel form activated carbon materials have been used. Such an activated carbon foam can be fabricated, i.e. sawed, machined and otherwise shaped to fit virtually any required filtering location by simple insertion and without the need for handling the “dirty” and friable particulate activated carbon foam materials of the prior art.

  • Patent number: 6734244
    Abstract: The present invention relates to a coating composition for fibrous substances containing 25 to 75 percent by weight of pigment, and 0.5 to 25 weight percent of a polymer comprising 1 to 15 percent by weight of one or more monomers having sterically hindered secondary amine groups and 10 to 40 weight percent of a carboxylic acid monomer. The coating is useful on fibrous and non-fibrous substrates on which liquid inks will be fixed. The non-ionic polymer becomes cationic when contacted by anionic inks, and the cationic nature of the coating provides the substrate with an excellent point of attachment for inks and dyes, resulting in bright, crisp printed images. The coating is especially useful for ink-jet printing on paper, paperboard, textiles, non-wovens, wood, and films.
