    Abstract: a process for the removal and recovery of sulfur oxides from gas streams by contacting the gas stream with an aqueous suspension of melamine containing an oxidation inhibitor such as para-phenylenediamine whereupon a mixture of solid, hydrated melamine sulfites and solid, hydrated melamine sulfate is formed. The solids are then separated from the reaction product and the clarified liquid recycled. The solids are then heated to temperatures up to 200.degree. C to decompose the hydrated melamine sulfites into free melamine, gaseous water, and sulfur dioxide, and the gaseous water and sulfur dioxide withdrawn as product. The hot solids are cooled and split into two portions. One portion is recycled and the other portion is treated with an aqueous inorganic base stronger than melamine such as ammonia or potassium hydroxide to decompose the contained melamine sulfate into free melamine and a basic sulfate salt solution. The basic sulfate salt solution is separated from the melamine and withdrawn as product and the melamine is recycled to the process.

    Abstract: A panel for absorbing mechanical impact energy includes a substrate and a multiplicity of fibers attached, by one of their ends, to the substrate with their other ends extending away from the substrate. The panel may include a thin, porous covering layer that overlies the free ends of the fibers. The porosity of the cover and the fiber density of the fibers may allow for breathability of the panel. The panels may be flexible and may be used in body protection devices such as helmets, body armor as well as in other environments. Panels may be configured in a variety of energy absorbing arrangements for differing applications.

    Abstract: A direct charging electrostatic flocking method is provided for the fabrication of a fibrous structure. Fibers are deposited directly on a first electrically conductive surface while a second electrically conductive surface with an adhesive thereon is disposed over the first surface. A vacuum is created in the space between the first electrically conductive surface and the second electrically conductive surface. The vacuum is then filled with sulfur hexafluoride gas. An electric field is generated between the first and second electrically conductive surfaces. The fibers leave the first electrically conductive surface, accelerate through the electric field and sulfur hexafluoride gas, and are coupled on one end thereof to the adhesive. As a result of using sulfur hexafluoride rather than air there is an increase in fiber density of the fibrous structure.

    Abstract: The present invention relates to the reaction of phosphate rock with nitric acid and urea to produce nitrogen-phosphorus containing slurries, which slurries, in turn, may be granulated and dried to produce solid N-P fertilizer products with agronomically advantageous low pHs (1.0-4.0). The products have excellent storage characteristics. The improved properties of these products result partially from the formation of a new compound, Ca(H.sub.2 PO.sub.4)(NO.sub.3).CO(NH.sub.2).sub.2, which was discovered during the course of the investigation that led to the instant invention.
