Abstract: A system and method for treating ballast water within an ocean going vessel by generating hypochlorite for treating the ballast water. The system comprises one or more hypochlorite electrolytic cells in fluid communication with a stream of ballast water. A chlorine analyzer is positioned downstream from the electrolytic cells to determine the chlorine concentration of the treated ballast water. A hydrogen separator is connected to the hypochlorite electrolytic cells for venting hydrogen. In the method of this invention, water is taken aboard the ship for ballast in one port. A treatment stream is separated from the ballast water stream and piped to hypochlorite electrolytic cells. Hypochlorite is generated into the treatment stream and the hydrogen byproduct is separated by the hydrogen separators. The treatment stream is then reintroduced to the ballast water to eliminate marine species and pathogenic bacteria from ballast water.

Abstract: A calcium supplement for animals comprising one or more coatings over a calcium-containing core. The coatings provide additional nutrients as well as providing a moisture-resistant outer coating to reduce the hygroscopic effects of the calcium-containing core. The supplement comprises calcium-containing core particles, calcium chloride for example, each particle having an animal nutrient coating over an outer surface of the core particles. The supplement further comprises a second coating, urea, deposited over the nutrient coating, and a final outer coating comprising one or more fatty acids or paraffinic hydrocarbons that are agreeable to animals. The method for making a calcium supplement for animals comprises coating calcium-containing granules with a layer of nutrients and then spraying molten soluble urea onto the previously coated calcium-containing granules which are sufficiently cool to solidify the molten material into second coating on the granules.

Abstract: A biologically active reactor system for the treatment of wastewater comprises one or more submerged denitrification reactors having coarse media particles and a fixed biological film comprising biologically anoxic active microorganisms. One or more submerged aerated filters are in fluid communication with the one or more submerged denitrification reactor, the submerged aerated filter comprising coarse media particles and a fixed biological film comprising biologically aerobic microorganisms for oxidation of organic matter. One or more deep bed denitrification filters for removal of suspended solids and denitrification of oxidized nitrogens are in fluid communication with the one or more submerged aerated filters, the deep bed denitrification filter comprising fine media particles of less than 6 mm. Effluent from the submerged aerated filter is recycled to the submerged denitrification reactor for pre-denitrification prior to being piped to the deep bed denitrification filter.

Abstract: A punctum plug includes a distal tip, a proximal cap and a body connecting the tip to the cap. The cap has a proximal surface which remains exposed in the eye upon implantation of the punctum plug. A passage for an insertion tool extends distally in the punctum plug from an opening along the proximal surface. One or more recesses in the proximal surface collect tear fluid by surface tension, and each recess is laterally offset in its entirety from the opening and does not overlap or align with the opening. The number of recesses is indicative of the size of the punctum plug. A method of punctal occlusion involves collecting tear fluid in the one or more recesses and adhering the tear fluid in the one or more recesses by surface tension.

Abstract: An epoxy composition for application to the surface of a marine vessel. The epoxy composition comprises an epoxy resin and an iron particulate combined with one or more materials, preferably dry materials, which are piped into a feeder and then into a mixer. The dry materials are selected from a group of one or more additives comprising a ceramic material, an amorphous fumed silica such as Cab-O-Sil®, a silicone and a color pigment. The combined mixture is then submitted to a polarizing process so that the iron particulate is magnetized to create a polarized, electromagnetic field. A second mixture comprising an epoxy hardener, a ceramic material and an amorphous fumed silica is produced for ultimately combining with the epoxy resin mixture at the point of application to the marine vessel.

Abstract: A polo training apparatus comprises a dummy horse and conveyor belts arranged one each side of the dummy horse. A ball located on one of the conveyor belts will be displaced relative to the dummy horse, thereby simulating the movement of the horse relative to the ground and the ball. The dummy horse may also be movable to simulate the movement of a horse and the speed of movement of the dummy horse may be linked to the speed of the conveyor belts to simulate the riding of a horse more closely.

Abstract: A system, method, and apparatus for managing a water supply in a water tank are presented herein. A submersible pump is placed inside the water tank. The thrust of the pump causes a considerable increase in water circulation about the water tank, thereby resulting in a more consistent water supply. Chemical disinfectants are added directly in front of the pump, thereby resulting in better mixing. Additionally an outlet from the pump provides a testable sample for measurement of the concentration of the chemical disinfectant. The measurements of the concentration of the chemical disinfectant are provided to a programmable logic controller which makes real time adjustments to the chemical disinfectants that are added.

Abstract: A method of installing a formed-in-situ repair in a pipe 40 comprising locating a sleeve of reinforcement material impregnated with a settable resin within a tube 36 of soft, impervious sheet material; everting the tube into said pipe such that the sleeve is carried into a desired zone and brought into intimate contact with its inner surface; guiding the point of eversion 43 of said tube through directional changes in the pipe with guiding means 21; maintaining the inflation of the everted tube while passing a heated fluid medium through its interior to accelerate curing of the settable resin; and, when the settable resin is cured, de-everting the tube with withdrawal means 19 and withdrawing it from the pipe, leaving the sleeve of reinforcement material in place within it.

Abstract: A fabric towel holder for hand towels comprises a fabric sheet that is twice-folded along its longitudinal axis to form a first panel, a third panel and a second panel positioned between the first panel and the third panel. The first panel comprises a first longitudinal end and the third panel comprises a second longitudinal end securely attached to the first longitudinal end. The longitudinally folded fabric sheet is also folded along its transverse axis to form a first segment having a first front side and a first back side, and a second segment having a second front side and a second back side. A fabric member is attached to the first front side so that the fabric member and first front side of the second panel define a pocket adapted for holding hand towels. A hook fastener is attached to the first back side and a loop fastener is attached to the second back side so that the loop fastener adheres to the hook fastener when the fabric sheet is folded along its transverse axis.
