Patent number: 6395245Abstract: A method for preparing a carbon-containing composition is disclosed which comprises the steps of introducing, into a hot gas, a dispersion obtained by dispersing, in a decomposable carbon compound, a metal oxide and/or a metal compound which can be converted into the metal oxide by heating, to form a carbon-containing composition containing simple carbon and the corresponding metal oxide; and then collecting the formed carbon-containing composition. This carbon-containing composition is useful for the manufacture of a ceramic powder for sintering.Type: GrantFiled: March 17, 1995Date of Patent: May 28, 2002Assignee: Mitsui Chemicals, Inc.Inventors: Tsuyoshi Yasutake, Hideaki Miyashita, Sadaichi Komohara, Hiroshi Masuda, Tadashi Yoshino, Fumio Nakamura, Nobuyuki Sutoh

Patent number: 6387500Abstract: A multi-layered coating for use preferably on paperboard or paper is disclosed wherein the coating contains at least two layers. The first layer contains at least one dark colorant, at least one white or near white pigment, and at least one binder, and the second layer contains at least one pigment other than a dark colorant, such as a white or near white pigment, and at least one binder. Slurries and dry mixtures containing these ingredients are also disclosed. A multi-layered coated paperboard or paper comprising paperboard or paper and the multi-layered coating is also disclosed. A method to reduce the amount of a white or near white pigment like titania is also disclosed which involves using one or more of the above-described multi-layered coatings on paperboard or paper.Type: GrantFiled: November 6, 1997Date of Patent: May 14, 2002Assignee: Cabot CorporationInventor: Sanjay Behl

Patent number: 6387498Abstract: A flake-based pigment is provided having improved specular reflectance characteristics in the visible wavelength range. The flake-based pigment has a plurality of core flake sections each formed of a central reflector layer and dielectric support layers on opposing sides of the reflector layer. The resulting core flake section is a very thin three-layered structure that exhibits a uniaxial compressive strength much greater than a corresponding uniaxial tensile strength. This structure provides the benefits of rigidity and brittle fracture during manufacturing and application processes, which ultimately provides favorable planar and specular reflectance characteristics for the pigment in the visible wavelength range. A variety of outer coating layers can be formed around the core flake sections, such as various dielectric and absorber layers having thicknesses dependent upon the desired optical characteristics of the pigment.Type: GrantFiled: April 7, 2000Date of Patent: May 14, 2002Assignee: Flex Products, Inc.Inventors: Kent E. Coulter, Thomas Mayer, Roger W. Phillips, John S. Matteucci
