Compositions comprising ammonium nitrate double salts
Patent No. 8,721,760
Preferred aspects of the present invention provide ammonium nitrate compositions comprising ammonium nitrate and at least a second compound, said second compound being present under conditions and in amounts effective to substantially reduce the detonation sensitivity of the composition and/or to otherwise improve a desired property of the composition. In certain embodiments, the second compound is selected from the group consisting of ammonium sulfate, ammonium phosphate, calcium nitrate, potassium nitrate, magnesium nitrate, ammonium molybdenate, ammonium hexaflouralsilicate, neodymium hydroxynitrate, and combinations of two or more of these. In preferred embodiments, at least a substantial portion of the ammonium nitrate in the composition is in the form of a double salt with one or more of said second compounds. In highly preferred embodiments, the present compositions consist essentially of one or more double salts of ammonium nitrate and a second compound as described herein.

Method and apparatus for the continous production of low concentrations of chlorine dioxide from low concentrations of aqueous chlorite
Patent No. 8,721,899
Provided are methods and systems for continuously producing low concentrations of chlorine dioxide from dilute solutions of sodium chlorite. The low concentrations of chlorine dioxide produced allow for reduced exposure risk with direct application of the chlorine dioxide stream. The incorporation of a suitable chlorine dioxide detector permits continuous monitoring and control of chlorine dioxide production ensuring that the process stays within regulatory guidelines. Pretreatment of reaction water is preferred for achieving suitable conversion rates of the low concentrations of chlorite to chlorine dioxide.

Air curtain system for an open-front refrigerated case with dual temperature zones
Patent No. 8,713,954
An open-front refrigerated display case is provided having a medium temperature zone disposed above a low temperature zone in a generally vertically-stacked arrangement. A spillover airflow-diverting device is disposed between the medium temperature zone and the low temperature zone and is configured to direct spillover air from the medium temperature zone air curtain (and ambient air entrained therewith) in a direction away from the open front of the low temperature zone. The spillover airflow-diverting device may include louvers configured to direct a gravity-induced flow of the spillover air in an outward direction away from the open front of the low temperature zone, or may include fans to collect spillover air and forcibly direct it in an outward direction away from the open front of the low temperature zone. The outwardly directed spillover air may be discharged in the form of an `outer layer` for an air curtain on the low temperature zone.

Process for forming an aramid copolymer
Patent No. 8,716,432
The invention concerns processes for forming a polymer comprising residues of 2-(4-amino phenyl)-5(6) amino benzimidazole (DAPBI), paraphenylene diamine (PPD), and terephthaloyl dichloride, comprising the steps of: (a) forming a slurry of DAPBI in a solvent system comprising an organic solvent and an inorganic salt; (b) adding terephthaloyl dichloride to the slurry terephthaloyl dichloride in the amount of up to one-half mole for every mole of DAPBI in the slurry; (c) agitating the slurry to react the DAPBI and terephthaloyl dichloride to form an oligomeric solution; (d) adding PPD to the oligomeric solution and agitating until substantially all of the PPD is dissolved, (e) adding terephthaloyl dichloride in an amount of greater than one mole for every mole of PPD in the solution to form a prepolymer solution; and (e) agitating the prepolymer solution to form a polymer.
