Abstract: Drying sodium borohydride dihydrate particles in a flowing stream of a chemically inert drying gas results in novel nearly odor-free, dust-free sodium borohydride particles which are free flowing without the need for anti-caking or flow additives. The dihydrate particles are preferably dried in a fluidized bed formed with a flowing stream of nitrogen.

Abstract: Disclosed are compositions containing biologically active compounds that slowly release the biologically active compound. These compositions may be directly incorporated into the locus to be protected or may be applied to a structure in a coating.

Abstract: Matrix-dyed textiles of cellulose acetate, cellulose triacetate, silk, wool, flax, nylon, acrylic, polyethylene terephthalate, cotton, and rayon are stripped of their dyes in a dye stripping system comprising a reducing agent in an aqueous bath produced by the reaction of a bisulfite with about 0.35% or less of a borohydride by weight of the textile. The borohydride may be added to an aqueous bath already containing the bisulfite and the textile or the borohydride and bisulfite may be mixed in an add tank and the mixture added to the aqueous bath. Chelating agents, sequestering agents, fire retardants, and odor scavengers are not needed. Reclaimed textiles having superior receptivity of a new dye are provided.

Abstract: Fluorescent dyes which fluoresce a variety of colors are prepared from substituted isoviolanthrone and substituted isoviolanthrone by reductive alkylation with alkyl halides in the presence of zinc.

Abstract: Disclosed is an improved method for the preparation of highly pure haloformimine compounds in high yields by reacting a formimine compound in a solvent with a halogenating agent while maintaining the pH of the halogenation reaction in the range of 2 to 5. The pH of the reaction may be maintained by a variety of means, such as by the addition of a base.

Abstract: A new method for the preparation of aminopropyl terminated or internal functionalized polyalkyl or aryl siloxanes is described. The method involves readily available commercial starting materials and proceeds under mild conditions in high yield. Purification is facilitated over present commercial procedures and a wider variety of internal functionalized siloxanes may be prepared. The method involves hydrosilation of commercially availably alkyl or aryl functional hydrosilicones with allyl amine or other alkenyl or arenyl amine in the presence of platinum (0) divinyltetramethylsiloxane or platinum (0) cyclovinyl complexes.

Abstract: An amorphous silicate pigment having a pore volume of at least about 4.0 ml/g as measured by mercury intrusion, a BET surface area of at least about 300 m2/g, and an Al2O3 content of about 2.0-10.0 wt % is provided. The invention can be successfully used in recording media coatings, particularly coatings for recording media used in ink jet printing systems.

Abstract: A method for predicting an intrinsic property of a mixture comprising at least two components by: (a) selecting components and an equation; wherein the equation relates amounts of the components to the intrinsic property of the mixture; (b) selecting experimental compositions, each of which comprises at least one of the components; (c) measuring a correlational property of each of the experimental compositions by a correlational technique; and (d) determining a set of coefficients for the equation; wherein in the equation, each of the coefficients is multiplied by a concentration of a component or a product of concentrations of two or more components.

Abstract: In an apparatus used for perfusion-treating objects within a defined treatment area of a liquid bath, the apparatus having a ring having a lower edge which is sealingly placeable on the bottom of the liquid bath and an interior for connection to a liquid conveying device. The ring includes a holding member for receiving an inlet member of the liquid conveying device, or a wall having at least one wall chamber which communicates with the holding member on the ring and with the interior of the ring.
