Publication number: 20040081827Abstract: A synthetic microsphere having a low alkali metal oxide content and methods of forming the microsphere and its components are provided. The synthetic microsphere is substantially chemically inert and thus a suitable replacement for natural cenospheres, particularly in caustic environments such as cementitious mixtures. The synthetic microsphere can be made from an agglomerate precursor that includes an aluminosilicate material, such as fly ash, a blowing agent such as sugar, carbon black, and silicon carbide, and a binding agent. The synthetic microsphere is produced when the precursor is fired at a pre-determined temperature profile so as to form either solid or hollow synthetic microspheres depending on the processing conditions and/or components used.Type: ApplicationFiled: August 25, 2003Publication date: April 29, 2004Inventors: Amlan Datta, Hamid Hojaji, David L. Melmeth, James A. McFarlane, Thinh Pham, Noel E. Thompson, Huagang Zhang

Patent number: 6670291Abstract: A laminate sheet material comprising a first layer comprised of polymeric material and a second layer comprised of non-metallic fibers. The first and second layers at least collectively contribute to the laminate having at least one of a passing Flammability Value, Flame Propagation Value or Burnthrough Value. The laminate sheet material is useful, for example, in vehicles (e.g., aircraft), insulation blankets, insulation systems, and systems for limiting exposure of flammable insulation to an ignition source.Type: GrantFiled: October 18, 2000Date of Patent: December 30, 2003Assignee: 3M Innovative Properties CompanyInventors: Thomas L. Tompkins, Margaret M. Vogel-Martin

Patent number: 6630226Abstract: A cutting line intended to trim and cut vegetation which can be used in rotary-head implements such as brush cutters and edge trimmers. The cutting line consists of a core of the monofilament type, which is coated with a granular coating, especially in the form of inorganic particles. The line thus has an uneven and/or rough surface appearance. The composite cutting line of this kind has a lower operating noise, a better cutting effect, and eliminates the problems of sticking and breaking at the eyelet in the rotary head.Type: GrantFiled: March 10, 1998Date of Patent: October 7, 2003Assignee: Speed FranceInventor: Emmanuel Legrand

Publication number: 20030180535Abstract: A composite powder containing a powdery base and aluminum hydroxide adhered to at least a portion of the surface of the base, wherein said adhered aluminum hydroxide in the form of a spherical and net structure is comprised preferably in a large amount. In case of using in powdery cosmetics, this composite powder hides wrinkles, pore openings and hard texture of the skin, and thus maintains the correcting effect of the troubled morphology of the skin. Thus, it exerts excellent effects of imparting natural gloss and color tone to the makeup coating without darkness, being superior in a feeling of “elasticity” and transparency, and the like, compared to the conventional products.Type: ApplicationFiled: February 25, 2003Publication date: September 25, 2003Inventors: Masaakira Horino, Miwa Ohara, Katsuki Ogawa, Sadaki Takata

Patent number: 6617013Abstract: A ceramic matrix composite material (10) having a plurality of interlaminar stitches (16) as shown in FIG. 1. The stitches are formed by directing laser energy into the material to melt and recast zones of the material in a direction transverse to the layers of reinforcing fibers(12). The stitches not only improve the interlaminar strength of the material, but they also increase the through-thickness thermal conductivity of the material, thereby reducing thermal-induced stresses. The zones of recast material (18) may define holes (20) extending at least partially through the thickness of the material. The holes may be filled with a filler material (24), thereby mitigating any adverse loss-of-area effect created by the holes.Type: GrantFiled: May 10, 2001Date of Patent: September 9, 2003Assignee: Siemens Westinghouse Power CorporationInventors: Jay A. Morrison, Gary Brian Merrill

Publication number: 20030118841Abstract: Nanoscale particles, particle coatings/particle arrays and corresponding consolidated materials are described based on an ability to vary the composition involving a wide range of metal and/or metalloid elements and corresponding compositions. In particular, metalloid oxides and metal-metalloid compositions are described in the form of improved nanoscale particles and coatings formed from the nanoscale particles. Compositions comprising rare earth metals and dopants/additives with rare earth metals are described. Complex compositions with a range of host compositions and dopants/additives can be formed using the approaches described herein. The particle coating can take the form of particle arrays that range from collections of disbursable primary particles to fused networks of primary particles forming channels that reflect the nanoscale of the primary particles. Suitable materials for optical applications are described along with some optical devices of interest.Type: ApplicationFiled: March 15, 2002Publication date: June 26, 2003Inventors: Craig R.

Publication number: 20030087119Abstract: A transparent conductive film has a polymer film 4 and a transparent conductive layer 5 formed on the polymer film 4. The transparent conductive layer consists of indium oxide, a zinc oxide system and a tin oxide system. A covering layer 9, made of material different from that of the transparent conductive layer 5, is formed on the transparent conductive layer 5. A touch panel is provided with the transparent conductive film as its upper electrode 6A or lower electrode. The surface of the transparent conductive layer is covered with the covering layer, so that physical or chemical stresses generated during the input to the touch panel do not affect transparent conductive layer directly, thus preventing damages and delamination of the transparent conductive layer. Furthermore, the covering layer formed on the transparent conductive layer improves the strength of the transparent conductive film, thereby enhancing a resistance to wear.Type: ApplicationFiled: July 15, 2002Publication date: May 8, 2003Applicant: BRIDGESTONE CORPORATIONInventors: Yoshinori Iwabuchi, Taichi Kobayashi, Shingo Ohno, Yukihiro Kusano, Masato Yoshikawa
