Abstract: A system for treating water for use in aquatics or recreational facilities is disclosed. The system includes a media filter vessel, a pressure sensor, and a monochromatic light source. A method of treating water for use in aquatics or recreational facilities is also disclosed. The method includes fluidly connecting a media filter vessel to a source of water for use in aquatics or recreational facilities, illuminating a media inside the media filter vessel, observing a monochromatic light source display a first indicator and observing a monochromatic light source display a second indicator. A method of retrofitting a media filter vessel is also disclosed. The method includes installing a pressure sensor on the media filter vessel, installing a monochromatic light source and operably connecting the monochromatic light source to a manual control and to the pressure sensor.

Abstract: A method of processing an explosive molding powder. The method comprises providing a nonaqueous slurry comprising at least one nitrate compound, an inert fluorocarbon medium, and, optionally, a water-reactive additive. The at least one nitrate compound comprises at least one nitramine, at least one nitrate ester, at least one nitrated aromatic, or mixtures thereof. A lacquer system comprising at least two organic solvents, at least one binder, and, optionally, at least one plasticizer is also provided. The organic solvents in the lacquer system may comprise at least one binder-soluble organic solvent and at least one binder-insoluble organic solvent. The nonaqueous slurry and the lacquer system are combined to form granules of the explosive molding powder. A lacquer system and solutions used in processing the explosive molding powder are also disclosed.

Abstract: Apparatus for machining workpiece made of an explosive material, the apparatus including: a drive system and a cutting tool assembly for cutting a workpiece made of an explosive material; an elongate member carried by, and projecting along an axis from, the drive system for holding the workpiece at a machining location while being rotated about the axis by the drive system; and a first shield element interposed between the machining location and the drive system for protecting the drive system against damage in the event of explosion of the workpiece.

Abstract: An improved process of making a highly impact insensitive form of HMX cal Alpha HMX has been accomplished. Test results of insensitive impact from drop heights of 5 to 10 times greater than Beta HMX, the conventional explosive, has been successfully achieved. This accomplishment has been achieved without the addition of any additives, and is attributed to the attainment of small particle size, whole crystals, narrow size distribution, and sample purity.

Abstract: 1,3,5-TRINITROHEXAHYDRO-1,3,5-TRIAZINE (RDX) is prepared in a new simplif and efficient manner which provides near quantitative yield. Our process is based upon the nitration of 3,7-DIACETYL 1,3,5,7 TETRAAZA[3.3.1.]BICYCLONONANE (DAPT).

Abstract: An improvement when 1,3,5,7-tetranitro-1,3,5,7-tetraazacyclooctane is preed by nitrolysis of 1,3,5,7-tetraacyl-1,3,5,7-tetraazaceyloctane with a solution of nitric acid and nitrogen pentoxide or phosphorous pentoxide. This improved process herein before set forth produces 99% yield and purity of product.

Abstract: 1-(n)-acetyl-3,5,7-trinitrocyclotetramethylenetetramine is prepared by nilysis of 1,3,5,7-tetracyl-1,3,5,7-tetraazacyclooctane with a solution of nitric acid and nitrogen pentoxide or phosphorous pentoxide.
