20150279596 | Insulated Thermal Cut-Off Device - A thermal cut-off device includes a plastic base, two electrodes, a temperature sensing element, and a plastic cover that fits over the base. The temperature sensing element is curved downward, and may be a bimetal or a trimetal. When the device is subject to an over-temperature condition, the orientation of the curve flips such that the temperature sensing element is then curved upward. When the temperature sensing element is curved upward, it lifts an arm of one of the electrodes, which severs the electrical connection between the electrodes. In this manner the device shuts off during an over-temperature condition in order to protect the circuit in which the device is installed. To prevent corrosion of the temperature sensing element, a first moisture insulation layer is applied to the outer surface of the thermal cut-off device. The moisture insulation layer may be an epoxy adhesive or a UV/visible light-cured adhesive or light/heat cured adhesive. In some embodiments, a second moisture insulation layer is formed on the surface of the temperature sensing element. | 10-01-2015 |

20090326211 | Process for concentrating and processing fluid samples - A method of treating a liquid sample having microbiological target species therein to concentrate the species and collect lysate is disclosed. The liquid sample comprises non-target microbiological particles, inorganic particles, and microbiological target species. The liquid is passed through a prefilter medium to allow the target species to pass through as filtrate and retain non-target microbiological products and inorganic particles thereon. The filtrate is contacted with a main filtration medium adapted to retain the target species thereon as retentate. The retentate is lysed to form a lysate containing target material that was enveloped within the microbiological target species. The microbiological species may comprise cell containing or viral material. Target materials comprise intracellular nucleic acids, or in the case of viral sampling, nucleic acids encased within the protein sheath or coating of the virus. | 12-31-2009 |

20130248443 | SELENIUM RECOVERY FROM BIOREACTOR SLUDGE - Wastewater, for example flue gas desulphurization blowdown water, containing soluble selenium is treated in a bioreactor. Microorganisms in the reactor reduce the selenium to elemental selenium, which is insoluble. The elemental selenium is discharged from the reactor in waste sludge also comprising biomass and other suspended solids. Non-microbial suspended solids are removed by way of acid dissolution followed by de-watering. The remaining sludge is burned at a temperature below the selenium oxidation temperature to remove biomass while leaving selenium particles behind. | 09-26-2013 |
