Patent number: 6716885Abstract: A storage-stable aerated gel composition comprising 30 to 97% by weight of water, 0.2 to 5% by weight of a gelling agent selected from xanthan gum, sodium alginate and neutralized carboxyvinyl polymer and 2 to 5% by weight of a fine particulate hydrophobic silicone-treated silica having a surface area of from 80 to 300 m2/g. The composition is in the form of fine particles of an aqueous gel containing the water and the gelling agent, the surface of which particles are coated with a coating of the finely divided particulate hydrophobic silica. The gel composition is prepared by mixing, under high shear conditions, the water and the fine particulate silica, and then adding to the resulting mixture, the gelling agent and mixing under high shear conditions.Type: GrantFiled: September 10, 2002Date of Patent: April 6, 2004Assignee: Sorex LimitedInventors: Roland Twydell, Lesley Le Quesne

Patent number: 6680066Abstract: The present invention relates to a composite material with an improved structure in which is dispersed an active organic compound, and a method for treating effluents, in particular a method for treating photographic effluents. The composite material takes the form of a structured gel comprising an aluminosilicate polymer matrix in the form of fibers in which at least two distinct fibers are interconnected by at least two covalent bonds to form an irreversible chemical gel and, dispersed in the matrix, an active organic compound. The choice of the degree of cross-linking of the matrix makes it possible to control the diffusion of a hydrophilic active organic compound. The invention further concerns a method for preparing such a composite material.Type: GrantFiled: February 5, 2002Date of Patent: January 20, 2004Assignee: Eastman Kodak CompanyInventors: Olivier J. Poncelet, Danielle M. Wettling
