.alpha.-Al.sub.2 O.sub.3 abrasive material and method of preparing the same: Patented by Peter Janz and Georg Gottschamel on September 1, 1987. Abstract: A sintered, microcrystalline abrasive material consists of at least 99.5%, by weight, of .alpha.-Al.sub.2 O.sub.3 crystallites having a size of less than 2 .mu. and the material having a density of at least 97% of the theoretical density. This abrasive material has a very high abrasive property and can be used in grinding bands or discs.
Antiperspirant-deodorant cosmetic products: Patented by Richard T. Murphy and M. Stephen LaJoie on April 7, 1993. Abstract: This invention provides a homogeneous antiperspirant cosmetic stick or roll-on product containing a deodorant ingredient which consists of particles that contain multiple fine crystallites of a bicarbonate compound encapsulated with a hydrophilic polymer coating that lowers the relative density of the particles and improves the dimensional stability of the cosmetic product.
Boehmitic Aluminas, and High-Temperature Stabile and Highly Porous Aluminum Oxides in a Pure Phase Which Are Obtained Therefrom: Patented by Klaus Noweck, Arnold Meyer, Reiner Glöckler, Frank M. Bohnen, Jens Juhl and Jürgen Schimanski on August 5, 1999. Abstract: The invention relates to crystalline boehmitic aluminas whose crystallites comprise exceptional differences of dimensions in the directions of space 020 and 120. The invention also relates to a method for producing the boehmitic aluminas and to resultant products obtained therefrom by calcination.
Carbon fibers and process for their production: Patented by Iwao Yamamoto and Hiroyuki Aikyo on October 3, 1994. Abstract: A carbon fiber which, when baked at a temperature of at least 3,000.degree. C., will have a spread La of graphite crystallites in the layer plane direction of more than 1,000.ANG., an electrical specific resistance of less than 1.1 .mu.OMEGA.m and a thermal conductivity of more than 1,100 W/m.multidot.K.
Carbon material for electric double layer capacitor, method of producing same, electric double layer capacitor and method of fabricating same: Patented by Michio Okamura and Makoto Takeuchi on August 3, 2001. Abstract: There is disclosed a carbon material from which an electric double layer capacitor (EDLC) having a large capacitance can be fabricated. First, a carbon material is activated to produce crystallites of graphite-like carbon having interlayer distances of 0.365 to 0.385 nm. Positive and negative plates are fabricated using the crystallites.
Catalytic Dewaxing Process: Patented by Guy Barre, Jean–paul Darnanville and Laurent G. Huve on November 16, 1999. Abstract: Process for the catalytic dewaxing of a hydrocarbon oil feed including waxy molecules and more than 500 ppmw of sulphur or sulphur containing compounds by contacting the oil feed under catalytic dewaxing conditions with a catalyst composition comprising at least a hydrogenation component, dealuminated aluminosilicate zeolite crystallites and a low acidity refractory oxide binder material which is essentially free of alumina.
CATHODE FOR AN ELECTRIC DISCHARGE TUBE: Patented by Petrus J.A.M. Derks on March 1, 1990. Abstract: Cathode for an electric discharge tube having a short warm-up time and a long lifetime. The cathode comprises a metal (particularly nickel) support base coated with a layer of potentially electron-emissive material, which support base has a thickness ranging between 20 and 150 .mu.m, and metal crystallites having a size which does not permit of any further crystallite growth or recrystallization. Preferably, the crystallites of the support base have a size which corresponds to the thickness of the support base.
Cathodoluminescent display apparatus and method for realization using diamond crystallites: Patented by James E. Jaskie, Lawrence Dworsky and Robert C. Kane on June 1, 1992. Abstract: Cathodoluminescent display apparatus employing an electron source including a plurality of diamond crystallites. Image display apparatus employing an array of picture elements, each picture element having associated therewith an electron source including electron emitting diamond crystallites, is realized as a preferred embodiment.
Chloroprene type rubber composition: Patented by Yasushi Abe, Mitsuyuki Nakada, Isao Yamagishi and Kazuomi Aoki on December 8, 2000. Abstract: A chloroprene type rubber composition which comprises a chloroprene type rubber, a carbon black having an average stacking height Lc of at least 2 nm in a C axis direction of the layer planes in the crystallites, and a zinc powder.
COMPACT POLYMER/METAL COMPOSITE PARTICLES, AQUEOUS DISPERSIONS THEREOF, PREPARATION AND USE IN BIOLOGICAL APPLICATIONS: Patented by Dominique Charmot on April 1, 1988. Abstract: Compact polymer/metal composite particles, sized or unsized, in which the metal is in the form of crystallites encapsulated in a polymer matrix. The composite particles may be prepared by introducing a metal complex into a swollen polymer in an organic liquid which is a solvent for the metal complex, followed by thermal decomposition of the metal complex and removal of the swelling organic liquid. The composite particles may be used in biological applications.
