  • Publication number: 20140141443
    Abstract: The invention is directed towards methods and compositions for identifying the specific microorganisms present in a particular potion of a papermaking processes. The method involves obtaining a sample from the process which is such that little or no live examples of the microorganism remain. However because DNA from the organisms is still present, an analysis which identifies portions of DNA specific to the particular organism will correctly identify the microorganism present. This allows for analysis of infestations present on felts or paper sheets which typically no longer have many live microorganisms on them when samples are taken for analysis.

  • Publication number: 20140124451
    Abstract: The invention provides methods and compositions for inhibiting the accumulation of DSP scale in the liquor circuit of Bayer process equipment. The method includes adding one or more GPS-surfactant based small molecules to the liquor fluid circuit. These scale inhibitors reduce DSP scale formation and thereby increase fluid throughput, increase the amount of time Bayer process equipment can be operational and reduce the need for expensive and dangerous acid washes of Bayer process equipment. As a result, the invention provides a significant reduction in the total cost of operating a Bayer process.

  • Patent number: 8716028
    Abstract: The invention is directed towards methods and compositions for identifying the amount of hydrofluoric acid in a buffered oxide etching composition. In buffered oxide etching compositions it is very difficult to measure the amount of hydrofluoric acid because it has varying equilibriums and it is toxic so it hard to handle and sample. When used to manufacture microchips however, incorrect amounts of hydrofluoric acid will ruin those chips. The invention utilizes a unique method of spectrographically measuring the hydrofluoric acid when in contact with added chromogenic agents to obtain exact measurements that are accurate, immediate, and safe.

  • Patent number: 8691994
    Abstract: The invention provides a composition and a method of using the composition for inhibiting the unwanted polymerization of ethylenically unsaturated monomers. The composition is prepared by reducing a nitroxide stable free radical to its corresponding hydroxylamine through reaction with a dialkyl/aryl hydroxylamine and subsequent addition of a polymerization prevention component selected from phenolic antioxidants, phenylenediamine and phenylenediamine derivatives, or phenothiazine and phenothiazine derivatives targeted towards ethylenically unsaturated monomers. The conversion of the nitroxide by the dialkyl/aryl hydroxylamine is to prevent it or the polymerization prevention component from being “spent”by reaction with each other, impurities or any other incompatible components. This allows previously incompatible combinations to now work effectively. In fact, the combination is more efficacious as the combination exerts a synergy due to the presence of various polymerization prevention reagents.

  • Patent number: 8668779
    Abstract: A method of simultaneously cleaning and disinfecting an industrial water system is described and claimed. The method involves the addition to the water of the industrial water system of a Compound selected from the group consisting of the alkali salts of chlorite and chlorate and mixtures thereof; and an acid, followed by allowing the water in the industrial water system to circulate for several hours. The reaction of the alkali salts of chlorite and chlorate and acid produces chlorine dioxide in-situ in the water of the industrial water system. The chlorine dioxide kills microorganisms and the acid acts to remove deposits upon the water-contact surfaces of the equipment. This cleaning and disinfecting method works in a variety of industrial water systems including cooling water systems.
