Abstract: The present invention comprises a computer-implemented visualization model of similarity relationships between documents. It comprises performing a similarity search based on at least one attribute of a reference document to find at least one target document with similar attributes; creating a visual representation of the reference database document and the at least one target document; creating a visual representation of the similarities between the reference document and the at least one target document; and displaying the visual representations of the database documents and their similarities on a graphical user interface. The target documents that are similarity searched may reside in a plurality of databases. The similarity search returns a result set of target documents that are used by the visualization model to create the visual representation of the documents and the similarities between the documents.

Abstract: Process for the production of solid ammonium polyphosphate in which ammonium phosphate melt is prepared in a pipe reactor and is solidified by controlled cooling to form crystals of a size and in quantity suitable to yield a hard, nontacky, and friable solid. Wet-process phosphoric acid is ammoniated in a pipe reactor to an NH.sub.3 :H.sub.3 PO.sub.4 mole ratio of about 1.0, and the resulting melt is agitated and simultaneously partially cooled by application of recycled pulverized product or air or a water jacket. The partially cooled melt is then solidified continuously into nontacky sheets on a water-cooled metal surface using warm water to slowly remove sensible heat and heat of crystallization. Up to about 55 percent or higher of the P.sub.2 O.sub.5 in the product may be polyphosphate. Without controlled cooling, a supersaturated solution or a microcrystalline texture results and the product is rather like a gel.

Abstract: Process for the production of granular mixed fertilizer in which ammonium phosphate melt is prepared in a pipe reactor and dispersed through a plurality of apertures in the wall of the pipe to bind small particles of fertilizer materials into granules. Wet-process phosphoric acid is ammoniated to an NH.sub.3 :H.sub.3 PO.sub.4 mole ratio of about 1.0 and the steam formed by the heat of reaction atomizes the ammonium phosphate melt resulting in proper distribution of the melt for granulation. Up to about 30 percent of the P.sub.2 O.sub.5 in the melt may be polyphosphate. The ammonium phosphate is essentially anhydrous and the granules of mixed fertilizers do not require drying. Elimination of drying greatly decreases investment, dust and fume evolution, and fuel requirement.
