Abstract:
An animal behavior modification system including a collar, a receiver device and a transponder. The receiver device is attached to the collar, the receiver device having a receiver circuit and a stimulation circuit. The transponder is in communication with the receiver device. The transponder is positioned proximate to the receiver device. The transponder includes a signal transmitter; and an antenna intermittently electrically connectable to the signal transmitter. The signal transmitter wirelessly communicating to the receiver circuit of the receiver device.
Abstract:
A signal transmitter system for an animal training system including an electrical impedance loop, a signal generator and a power supply. The signal generator is connected to the electrical impedance loop. The signal generator provides a current signal to the electrical impedance loop. The power supply provides a voltage level to the signal generator. The voltage level is dependent upon a measured characteristic of a voltage signal that results from an interaction of the current signal with the electrical impedance loop.
Abstract:
Described is an animal containment system for containing an animal within a boundary, for maximizing the animal's usable area within the boundary, for not discouraging the animal from returning to within the boundary in the event the animal moves beyond the boundary, and for doing so without utilizing an independent polarity indicator. The animal containment system determines whether the animal is within the boundary or beyond the boundary by considering the polarity of an activation signal the animal containment system transmits from the boundary and receives at the location of the animal. The animal containment system determines the polarity of the activation signal by modulating the signal such that the modulation indicates the polarity of the activation signal. The animal containment system achieves the above-discussed features by delivering a stimulus to the animal only when it traverses the boundary from within the boundary.

Abstract:
A two step method for solid state polymerization of dry crystalline thermoplastic polymers to form polymers with superior mechanical properties, first by mechanically fluidizing dry crystalline thermoplastic polymer particles in the absence of oxygen by means of blades moving through the fluidized polymer particles at velocities sufficient to heat the particles to an incipient melt temperature and maintain the temperature until solid state polymerization provides the desired molecular weight and before chemical degradation of the polymer occurs; and second by immediately quenching by application of liquefied cryogenic gases directly to the surfaces of the polymer particles in amounts sufficient to cool the particles to temperatures lower than the glass transition temperature of the polymer before crystals in the polymer aggregate into large spherulites.
Abstract:
A four step method of preparing palatable anionic mineral feed concentrate granules which form storage stable blends with feed rations to prevent parturient paresis in commercial breeding animals, with the four steps comprising: metathetically reacting ammonium sulfate with a molecular excess of magnesium chloride in acidic water to form an ammonium chloride, magnesium sulfate, magnesium chloride anionic salt solution; mixing the anionic solution with comestible proteinaceous feed particles to form damp concentrate particles; mixing the damp concentrate particles with a palatability enhancing molasses binder to form damp concentrate granules; and, drying the granules to form dry palatable anionic feed mineral concentrate granules which exhibit an excess of the strong anions, chloride and sulfate, over the strong cations, sodium and potassium. The attrition resistant granular concentrate composition may be effectively blended with animal feeds to form storage stable feed rations for commercial breeding animals for preventing parturient paresis.
Abstract:
A method preparing controlled release nitrogen in particulate fertilizers which exhibit single growing season availabilities to plants of about 80 percent or higher. The method utilizes relatively low urea and ammonia to formaldehyde mol ratios of about 1.7 urea to 0.1 ammonia to 1 formaldehyde to assure high conversions to controlled release nitrogen with low free ureas, and carefully controlled elevated temperatures, acid dehydration condensation catalyst concentrations and short dehydration reaction times of about 2-4 minutes to provide effective conversion of hydroxymethyl nitrogen compounds by dehydration condensation reaction to controlled release methylene nitrogen compounds. Quick neutralization of the dehydration catalyst in a turbulent mixing reactor minimizes the formation of undesirable methylene nitrogen polymers which are hot water insoluble and unavailable to plants in a single growing season.
Abstract:
A method of preparing liquid nonpolymeric controlled release nitrogen plant food composition by the condensation reaction of about one molecule ammonia, about two molecules of urea, and about three molecules of formaldehyde in base buffered aqueous solution at a minimum pH of 7 and a temperature of about 100.degree. C. and concentrating by evaporation until nitrogen concentration is between 20 and 30 percent before formation of polymers containing more than 3 urea moieties occurs. The new nonpolymeric aqueous liquid controlled release nitrogen plant food composition prepared exhibits high storage stability, low phytotoxicity, high nitrogen availability to plants, and contains less than 6 percent unreacted urea nitrogen, less than 1 percent unreacted ammonia nitrogen, and contains large amounts of 5-methyleneuriedo-2-oxohexahydro-s-triazine.
Abstract:
A method of preparing fire retardant concentrates wherein a base soluble cyanurate is dissolved in base and mixed with a fluid thermoplastic polymer. An amino-s-triazine is then reacted in-situ with the solubulized cyanurate to precipitate very fine insoluble cyanurate-amino-s-triazine adduct evenly distributed in the polymer. The mixture is cooled below its solidification point, binding the film particles of the insoluble adduct together by a matrix of solid thermoplastic polymer. The solidified matrix bound adduct is comminuted to form particulate thermoplastic fire retardant concentrate. The fluid thermplastic polymer may be a melt or an aqueous dispersion of a stable polymer such as nylon, polyolefin, polycarbonate, polyester, polystyrene, and polybutadiene. The particulate granules may contain concentrations as high as 65 to 95 percent of the adducts produced from soluble cyanurates such as sodium isocyanurate, and base solubulized isocyanuric acid and chlorocyanuric acid. Effective amino-s-triazines include melamine, melamine phosphate, and methylol melamine.
Abstract:
A one-step method of preparing coated particulate plant nutrients wherein a polyfunctional coupling agent is applied to a mobile mass of plant nutrient particles containing functional groups which are chemically reactive with the functional groups of the coupling agent, while simultaneously applying a second reactive material containing functional groups also reactive with the functional groups of the coupling agent, maintaining the mobile mass at a temperature between 30.degree. C. and 300.degree. C. until a strong, water-insoluble particle. The product of the one-step method is a controlled-release plant nutrient having excellent attrition resistance.
