20080227666 | RECONDITIONING PROCESS FOR USED HYDROCARBON BASED STIMULATION FLUID - A process treats a fluid stream of used fracturing fluid containing contaminants and forms a reconditioned fluid stream. Contaminants are removed by the combination of distillation, electrostatic agglomeration, decanting, and filtration or by distillation and optional filtering. Optionally, in each case, the filtered fluid stream is treated in a clay tower to remove residual contaminants. | 09-18-2008 |

20110005999 | RECYCLING AND TREATMENT PROCESS FOR PRODUCED AND USED FLOWBACK FRACTURING WATER - A portable water recycling and treatment system and process for used and produced flowback frac water pumps the water from a collection tank through a series of dedicated hydration, retention and filtering tanks and vessels that provide treatment for the removal of chemicals, sediments and other containments. The system, which is enclosed, can be readily assembled on-site by interconnecting the dedicated tanks, vessels and pumps. The tanks and vessels may be situated in a plurality of trailers/units that are transported separately to the site. | 01-13-2011 |

20140067391 | Method and System for Predicting Speech Recognition Performance Using Accuracy Scores - A system and method are presented for predicting speech recognition performance using accuracy scores in speech recognition systems within the speech analytics field. A keyword set is selected. Figure of Merit (FOM) is computed for the keyword set. Relevant features that describe the word individually and in relation to other words in the language are computed. A mapping from these features to FOM is learned. This mapping can be generalized via a suitable machine learning algorithm and be used to predict FOM for a new keyword. In at least embodiment, the predicted FOM may be used to adjust internals of speech recognition engine to achieve a consistent behavior for all inputs for various settings of confidence values. | 03-06-2014 |

20090322452 | HANDLE ARM AND UNDERVOLTAGE RELEASE AND CIRCUIT INTERRUPTER INCORPORATING THE SAME - A handle arm assembly is for a circuit interrupter including an undervoltage release mechanism having a reset mechanism. The handle arm assembly includes a body portion rotatable through an arc between an on position, an off position, and a reset position beyond the off position and an arm portion projecting laterally from the body portion out of the plane of the arc through which the body portion rotates. The body portion and the arm portion are formed from a single piece of material wherein the body portion and the arm portion are different portions of the single piece of material. The arm portion is structured to engage the reset mechanism in a manner such that arcuate movement of the arm portion as the body portion moves to the off position is translated into actuation of the reset mechanism. | 12-31-2009 |

20110309052 | MOVING SEAL WITH ARC CREEPAGE SURFACE FOR AN AIR CIRCUIT BREAKER - A moving seal for an air circuit breaker provides an arc creepage surface that is positioned between a pair of separable contact assemblies when the moving seal is fit into an inlet of the arc chamber. The arc creepage surface has a surface contour that increases a length of an arc travel path between the separable contact assemblies, relative to a straight line distance between of separable contact assemblies. | 12-22-2011 |

20100170875 | ARC RUNNER ASSEMBLY AND ELECTRICAL SWITCHING APPARATUS AND METHOD INCORPORATING SAME - A circuit breaker includes a conductor, a fixed contact connected to the conductor, and an arc runner disposed on the conductor adjacent the fixed contact. The arc runner includes a first portion abutting the fixed contact and a second portion disposed in a recess of the circuit breaker housing. The arc runner is adapted to draw an arc from the fixed contact. A circuit breaker operating mechanism cooperates with a movable contact for opening and closing the fixed contact and the movable contact. An arc chute is adjacent the arc runner. A trip unit cooperates with the operating mechanism to trip open the fixed and movable contacts. | 07-08-2010 |
