Abstract: A stable fluid polymer suspension is composed of at least one water soluble polysaccharide polymer in an aqueous carrier fluid in which the polysaccharide polymer does not significantly swell or dissolve where the polysaccharide polymer in the aqueous carrier fluid has the measured properties of:i) rendering the polymer(s) insoluble, resulting in a cloudy dispersion,ii) limiting the swelling of insolubilized polymer(s), leading to a polymer sediment volume of a 1 weight percent polymer dispersion to less than 1%, andiii) preventing phase separation for at least one week.This invention also Includes a method of preparing the stable fluid polymer suspension having the above mentioned measured properties. The stable aqueous fluid suspension of this invention is a clear, odorless, and stable formulation and is used in cosmetics, personal care, and household products.

Abstract: This invention relates to new crystalline organic compositions having unique combinations of framework-confined uniform mesopores and textural mesopores and to a method for their preparation. The compositions typically possess a framework wall thickness of at least about 17.ANG., small elementary particle size of less than about 400.ANG., and ratio of textural to framework-confined mesoporosity of greater than about 0.2. The formation of the mesoporous structure is accomplished by a novel self-assembly mechanism involving hydrogen bonding between neutral amine surfactant (S.degree.) and neutral inorganic oxide precursor (I.degree.). This S.degree.I.degree. templating approach allows for facile and environmentally benign recycling of the cost-intensive template by simple solvent extraction methods.

Abstract: A method which enables economical and highly effective preparation of refined kaolin clay products having preselected particle size distributions and brightnesses, by means of separate, efficient and economical processing of at least two crude components. A fine particle size kaolin crude having a PSD such that at least 85% by weight of the particles are of less than 2 micrometers ESD is wet beneficiated to provide a first product component having a PSD of at least 95% by weight less than 2 micrometers and a brightness of at least 89 on the G.E. scale. This wet beneficiation is conducted without use of a froth flotation step. A coarse particle size kaolin crude having a PSD such that less than 85% by weight of particles are of less than 2 micrometers ESD, is separately wet beneficiated to produce a second product component having a PSD of no more than 85% by weight less than 2 micrometers and a brightness of at least 89 on the G.E. scale.

Abstract: Fine and homogeneous oxide particles for superconductors which can be sintered at a low temperature are prepared in a liquid phase by the sol-gel method using alkoxides as starting materials. By forming a buffer layer between a substrate and a superconducting film, good-quality and oriented superconducting film can be fabricated. Highly c-axis-oriented superconducting film and bulk products can be prepared from particular starting compositions in Ln-Ae-Cu-O and Bi-Ae-Cu-O systems. The oriented film can be produced by painting a paste of such starting compositions on a substrate followed by sintering, and the bulk form can be produced by pressing the pre-sintered powder of such starting compositions.

Abstract: A high discharge rate electrochemical battery structure is disclosed as having a perforated disc electrode stack comprising pluralities of disc electrodes respectively connected to a pair of busbars. Each disc electrode has a tab with two fins which are bent at 90 degrees to the disc electrode. Each fin is inserted between two parts of the corresponding busbar and welded thereto. The design of the busbars and disc electrodes provides for redundancy of electrical contact, high thermal and electrical conductivity and improved resistance to mechanical shock.
