20120039792 | METHOD FOR GROUND WATER AND WASTEWATER TREATMENT - Described is a method of water treatment including the steps of: a) Stripping water or dissolved gas by an inert gas b) Subjecting water to oxidation treatment to precipitate metals; and c) Removing precipitates from water. Oxidation treatment is a multi-stage oxidation treatment including the stages of: (1) contacting water with oxidant under pressure to precipitate metals from water; and (2) catalytic oxidation of water with oxidant, oxidation being catalysed by a catalyst, such as a zeolite catalyst, in a bed reactor or filter. Inert gas stripping is aimed at preventing growth of iron bacteria in the treatment system. Pressurised oxidation reduces the amount of oxidant injection required for catalytic oxidation. The method is particularly suited to removal of contaminants such as iron, manganese and arsenic from ground water. | 02-16-2012 |

20100290857 | ELASTIC JOINT ELEMENT AND FASTENER ASSEMBLY INCORPORATING THE SAME - A fastener assembly for use in a joint in a work-piece comprises a first fastener component for extending through a hole in the work-piece, a second fastener component and a resilient element. The first component has a first contact portion for engaging the work-piece. The second fastener component has a second contact portion for cooperating with the first fastener component to compressively load the work-piece thereby forming the joint. The resilient element is located between the first and second contact portions so that it is it is compressed under load. The resilient element has a first stiffness characteristic when subjected to loading less than a predefined amount and has a higher stiffness characteristic when subjected to loading more than the predefined amount. | 11-18-2010 |

20140238149 | CORIOLIS FREQUENCY TRACKING - Motion is induced in a conduit such that the conduit vibrates in a major mode of vibration having a major amplitude and a minor mode of vibration having a minor amplitude. The major amplitude is larger than the minor amplitude, the major mode of vibration has a first frequency of vibration and the minor mode of vibration has a second frequency of vibration, and the minor mode of vibration interferes with the major mode of vibration to cause a beat signal having a frequency related to the first frequency of vibration and the second frequency of vibration. The frequency of the beat signal is determined, and the second frequency of vibration is determined based on the determined frequency of the beat signal. | 08-28-2014 |

20080294366 | SENSOR FUSION USING SELF EVALUATING PROCESS SENSORS - A measurement processing system is disclosed for fusing measurement data from a set of independent self-validating (SEVA™) process sensors monitoring the same real-time measurand in order to generate a combined best estimate for the value, uncertainty and measurement status of the measurand. The system also provides consistency checking between the measurements. The measurement processing system includes a first process sensor and a second process sensor. Each of the first and second process sensors receive a measurement signal from a transducer and generate independent process metrics. A measurement fusion block is connected to the first and second process sensors, the measurement fusion block is operable to receive the independent process metrics and execute a measurement analysis process to analyze the independent process metrics and generate the combined best estimate of the independent process metrics. | 11-27-2008 |

20100023331 | Speech recognition semantic classification training - An automated method is described for developing an automated speech input semantic classification system such as a call routing system. A set of semantic classifications is defined for classification of input speech utterances, where each semantic classification represents a specific semantic classification of the speech input. The semantic classification system is trained from training data having little or no in-domain manually transcribed training data, and then operated to assign input speech utterances to the defined semantic classifications. Adaptation training data based on input speech utterances is collected with manually assigned semantic labels. When the adaptation training data satisfies a pre-determined adaptation criteria, the semantic classification system is automatically retrained based on the adaptation training data. | 01-28-2010 |

20140163959 | Multi-Domain Natural Language Processing Architecture - An arrangement and corresponding method are described for multi-domain natural language processing. Multiple parallel domain pipelines are used for processing a natural language input. Each domain pipeline represents a different specific subject domain of related concepts. Each domain pipeline includes a mention module that processes the natural language input using natural language understanding (NLU) to determine a corresponding list of mentions, and an interpretation generator that receives the list of mentions and produces a rank-ordered domain output set of sentence-level interpretation candidates. A global evidence ranker receives the domain output sets from the domain pipelines and produces an overall rank-ordered final output set of sentence-level interpretations. | 06-12-2014 |
