Abstract: A moving bed filtration process for the production of sphere based crystals is disclosed. Sphere based crystals having an opal-like structure or an inverse opal-like structure can be produced in accordance with the invention.

Abstract: The invention relates to particles with opalescent effect—especially 3-D structural color pigments-based on solid colloidal crystals of monodispersed spheres and the manufacturing processes suitable for large-scale production of such solid colloidal crystal products. The particles with opalescent effect contain a sphere based crystal structure (or super-lattice) built up by monodisperse spheres and one or more secondary types of much smaller colloidal particles occupying partially or completely the empty spaces between the monodisperse spheres.

Abstract: A package for at least one bottle comprises a carton, a honeycomb core within the carton for surrounding the bottle, as well as bottom and top honeycomb pads abutting the honeycomb core. The honeycomb core is severed from its outer skin through the honeycomb material to its inner skin so that it may be folded to form an enclosure about the bottle. The bottle has the same height as the honeycomb core and when covered at its ends by the honeycomb pads positioned beneath and on top of the honeycomb core provides an assembly which completely fills the carton. In one embodiment of the invention, four bottles are contained within a square carton and are held in place by two G-shaped honeycomb core portions which cooperate to form four compartments for holding the bottles. In another embodiment, six bottles are packaged in a rectangular carton with the honeycomb core substantially formed by a continuous honeycomb panel severed to allow folding into six compartments.

Abstract: Stable, low viscosity, thixotropic, broad spectrum, sprayable sunscreen compositions suitable for topical application to human skin and hair are provided, along with a method for their preparation. The compositions comprise oil-in-water suspoemulsions containing dispersing agents to disperse inorganic sunscreen. The compositions are easy to apply to the skin and are practically non-whitening when applied on skin.

Abstract: A dual particle immunoassay method and kit for detecting analyte in a sample in which the sample to be analyzed, a binding molecule specific for the analyte, and a particle coated with the analyte to be detected or coated with a second binding molecule are reacted and applied to a porous membrane. The competitive immunoassay utilizes an analyte-coated particle, whereas the sandwich immunoassay employs a second binding molecule-coated particle. All of the reagents except for the coated particle are able to pass through the porous membrane. Detectable particles coated with a binding substance that binds to the binding molecule, such as protein A protein G, second antibody reactive to the binding molecule, or a small synthetic affinity ligand, are reacted with coated particles retained on the membrane surface. The detectable particles will pass through the membrane if not complexed with the coated particle.

Abstract: A preparative chromatographic cyclical process utilizing a single column comprising, at steady state: (a) establishing and maintaining a circulating chromatographic profile through said column and through one solvent pump; (b) discontinuously and periodically injecting a sample comprising at least two components, into the interior of said maintained circulating profile; and (c) collecting, discontinuously and periodically, at least two enriched fractions from said circulating profile.

Abstract: Disclosed herein is a method of producing pearlescent pigments comprised of a platelet substrate and a TiO.sub.2 coating, which has a rutile structure and which does not contain foreign metal species. The method entails the deposition of Ti(III), followed by the deposition of a Ti(IV), onto the platelet substrate.

Abstract: Reagents, immunoassay methods, and kits for detecting the presence or amount of trichloroethylene or perchloroethylene in a sample. Reagents include antibodies, immunogens for preparing antibodies, and assay conjugates. The immunogens elicit high affinity antibodies to trichloroethylene. The antibodies have minimal crossreactivity to other halogenated and aromatic hydrocarbons. The assay conjugates provide for sufficient binding of the antibody to the conjugate with maximum inhibition of that binding by free trichloroethylene and perchloroethylene in the sample. The reagents are useful in immunoassays to detect trichloroethylene and perchloroethylene, especially in environmental samples. Kits contain antibodies specific for trichloroethylene and perchloroethylene and assay conjugates.
