  • Patent number: 5698210
    Abstract: Controlled release compositions of matter are disclosed comprising complexes for treating a population of one or more aquatic organisms in a column of water. The complexes comprise at least one system wherein the system comprises at least one bioactive agent as a component selected for treating a population of aquatic organisms, at least one carrier component, and at least one coating component for regulating the controlled release rate and release profile of the bioactive agent in water or at least one bioactive agent and one joint-function component that can serve as both a carrier and coating to regulate the controlled release rate and release profile of the bioactive agent in water, with or without optional binder components and/or additional formulation materials. The components are selected to sink or float so that the complexes will permeate and/or remain in any planar or volumetric segment of a water column for a period of time that is sufficient to effectively treat a population of aquatic organisms.

  • Patent number: 5679364
    Abstract: The invention provides contaminant-reducing agent delivery compositions that are useful for the control of organic or inorganic contaminants in aquatic or terrestrial environments. The compositions comprise one or more superabsorbent solid organic polymers and at least one contaminant-reducing agent. These superabsorbent polymers act as the primary carriers of one or more contaminant-reducing agents effective for the control of organic or inorganic contaminants in aquatic or terrestrial environments. Contaminant-reducing agents include film-forming agents, microbial agents, nutrient agents, and mixtures thereof. The invention also provides a method to entrap and accumulate organic and inorganic contaminants in one or more superabsorbent polymer compositions containing no contaminant-reducing agent. The invention also provides a method to entrap water in superabsorbent polymers to activate natural and applied microbial and nutrient contaminant-reducing agents in terrestrial environments.

  • Patent number: 5567430
    Abstract: Superabsorbent solid organic polymers which absorb over 100 times their weight in water are used in aquatic environment insect population control compositions. Methods for using the superabsorbent polymer insecticidal delivery agents for the control of aquatic environment insect populations, including mosquito population control methods, in an area needing aquatic environment insect population control treatment or in a dry area that is expected to need aquatic environment insect population control, are described.

  • Patent number: 5410327
    Abstract: A stabilized antenna mount system is described which includes an antenna subassembly, a means for allowing the subassembly to rotate in three dimensional planes, and a means for stabilizing the subassembly. The subassembly rotates by means of a multi-axis bearing and is stabilized with an inertia mass attached to its lower portion. The inertia mass has a weight approximately six times the combined weight of the subassembly and the multi-axis bearing.

  • Patent number: 5357429
    Abstract: Three-dimensional models are constructed from two-dimensional tomographic data collected from contiguous, substantially parallel, cross-sectional tomographic slices through an imaged object. The scan angle of each cross-sectional tomographic slice is variably disposed at a predetermined, non-perpendicular angle with respect to a longitudinal axis through the scanner/imaged object to better depict certain structures and/or shapes of the scanner/imaged object. Optimum scan angle generated two-dimensional tomographic data is selected to reconstruct three-dimensional images depicting the surface and/or interior structure of the imaged object. The optimum two-dimensional data set is supplied to a three-dimensional model generator to form a three-dimensional model of the imaged object.

The subassembly rotates by means of a multi-axis bearing and is stabilized with an inertia mass attached to its lower portion. The inertia mass has a weight approximately six times the combined weight of the subassembly and the multi-axis bearing. Optionally, to counter the effects of the wind, a set of fins, with or without an aerodynamic upper housing, or a protective shield may be attached.

  • Patent number: 4985251
    Abstract: Superabsorbent solid organic polymers which absorb over 100 times their weight in water are used in flowable, aquatic environment insect population control compositions of varying viscosities. Methods for using the superabsorbent polymer insecticidal delivery agents for the control of aquatic environment insect populations, including mosquito population control methods, in an area needing aquatic environment insect population control treatment, or in a dry area that is expected to need aquatic environment insect population control, are described.

  • Patent number: 4983390
    Abstract: Superabsorbent solid organic polymers (such as acrylamide and acrylate polymers, co-polymers and ter-polymers, optionally grafted) which absorb over 100 times their weight in water are used in natural or artificial, terrestrial environment insect (such as fire ants) or pest population control compositions. Methods for using the solid or flowable superabsorbent polymer insecticidal/pesticidal delivery agents for the control of terrestrial insect or pest populations or for the simultaneous or concurrent control of both terrestrial insect and habitat-associated/related pest populations, in an area needing terrestrial environment insect and/or pest control treatment are described.

  • Patent number: 4451379
    Abstract: A method for removing leaves, pieces of bark, surface scum and debris from a swimming pool, fountain or other impounded body of water comprises forming on the surface of the water in the pool an approximately monomolecular film of a nonionic autophobic liquid organic material having an HLB number of 10 of less, a boiling point of 170.degree. C. or higher and a bulk viscosity less than 1000 centistokes under conditions of use, which film pushes leaves, solids, semisolids, surface scum and debris to a preselected region of the pool, fountain or impounded body of water and compacts the foreign matter for easy removal.
