  • Patent number: 7141605
    Abstract: A method of treating plant and animal systems and inanimate surfaces for the purposes of controlling plant pests, introducing pesticides and nutrients into plants, mitigating frost damage to plants, increasing crop yields, controlling certain plant diseases, controlling arthropod, bacterial, fungal, mycoplasma, rickettsia, and viral pests of animals and humans, and disinfecting inanimate surfaces. The method utilizes the unique multi-directional dispersion property of the tannate complex of picro ammonium formate and the tannate complex of picro cupric ammonium formate, in aqueous solution, combined with a minor amount of a surfactant sufficient to prevent formation of ammonium picrate, to penetrate plant and animal systems and inanimate surfaces and travelling multidirectionally therein. The method is carried out by introducing a small but effective amount of the tannate complex to the plant or animal system or inanimate surface.

  • Patent number: 6858649
    Abstract: The selective potentiation and/or inhibition of the 5-HT2A and/or 5-HT1A response to serotonin (5-HT) is achieved using analogs of oleamide. Selective potentiation and/or inhibition of the 5-HT2A and/or 5-HT1A leads to a modulation of serotonergic signal transduction of cells having various receptor subtypes. A subset of analogs is identified that inhibits rather than potentiates the 5-HT2A, but not the 5-HT1A, receptor response. These analogs enable the selective modulation of serotonin receptor subtypes and even have opposing effects on the different subtypes. An analysis of the activity of the oleamide analogs discloses that the structural features required for activity are highly selective. In particular, the presence, position, and stereochemistry of the 9-cis double bond is required and even subtle structural variations reduce or eliminate activity.

  • Patent number: 6620441
    Abstract: In producing aqueous microbiocidal solutions by oxidation of a water-soluble alkali metal bromide, an intolerable loss of active halogen species has been found to occur during a 10-day period immediately after the product solution has been formed. Surprisingly, this loss has been found to result from an alcohol impurity in the alkali metal bromide used in the process. By eliminating or at least sharply reducing the amount of alcohol impurity in the reaction mixture, products are formed which do not undergo the intolerable loss of active halogen content during the 10-day period.

  • Patent number: 5010069
    Abstract: An aqueous solution of 5-aminosalicylic acid (5-ASA) and a nontoxic alkali, alkali metal or alkaline earth metal salt of 5-aminosalicylic acid having a pH of 3-5 is disclosed. The sole buffer in the solution is that intrinsically formed by 5-aminosalicylic acid and its alkali, alkali metal or alkaline earth metal salt. The solutions preferably also contain an antioxidant and a metal complexing agent. In preferrred practice, the 5-ASA salt is formed in situ by addition of an alkali, alkali metal or alkaline earth metal hydroxide to a solution of 5-ASA. The solution is stable and does not significantly discolor due to 5-ASA decomposition for extended periods of time.

  • Patent number: 4908215
    Abstract: A one step process providing timed exposure to a substantially constant concentration of hypochlorite disinfectant is described, said process being completed when the hypochlorite is destroyed in an autocatalytic reaction with thiosulfate. The hypochlorite lifetime is precisely controlled by adjusting the initial pH of an alkaline disinfection solution of thiosulfate and hypochlorite, said solution containing a molar ratio of between 0.25 and 0.75 moles of thiosulfate to 1.00 mole of hypochlorite. Subsequently, with gradual evolution of acid and decreasing pH, the acid-dependent autocatalytic oxidation of thiosulfate is accelerated. This consumes the hypochlorite in a brief time interval, terminating the disinfection process. Also included in said alkaline disinfection solution is an appropriate concentration of Na.sub.2 HPO.sub.
