Abstract: A method for shutting off a wet interval of a wellbore includes producing hydrocarbons from a hydrocarbon bearing subterranean formation through a production string installed in the wellbore, identifying the wet interval of the wellbore, perforating the production string in the wet interval using an explosive-free punch tool to produce a plurality of openings in the production string, isolating the production string in the wet interval, treating the wet interval with a sealing composition injected through the plurality of openings into an annulus of the wellbore in the wet interval, and restoring a fluid flow path through the production string in the wet interval. The restored fluid flow path through the wet interval enables continued production of hydrocarbons from downhole intervals, while the sealing composition cured in the annulus provides a barrier to prevent fluid flow from the wet interval into the production string.

Abstract: A method and apparatus for managing a managed device on a network. An agent is run on the managed device. During runtime of the agent on the managed device, the agent receives dynamic trap parameter update values from network management station software running on a manager computer. The agent uses the dynamic trap parameter update values to set dynamic trap parameter values including trigger parameter values defining conditions for sending a dynamic trap. After setting the dynamic trap parameter values, the agent monitors the managed device to identify occurrence of an event that satisfies the conditions defined by the trigger parameter values. In response to identifying the occurrence of the event, the agent sends the dynamic trap to the network management station software running on the manager computer.

Abstract: The invention is a sliding latch with a bolt sliding in and out of a primary housing from a closed condition to an open condition on a sled that also slides in the housing. A spring biases the bolt to extend out of the housing to the closed condition. The bolt can be moved to an open condition by an electric motor mounted on the sled that rotates a threaded member to move a nut in a cavity in the bolt that pulls the bolt against the spring bias. The bolt can also be moved to an open condition by a force directly on the bolt against the spring bias. The bolt can also be moved to an open condition by a force pulling on the sled to move the sled and nut so the nut pulls the bolt against the spring bias to an open condition.

Abstract: Multiple groups of sensors are circumferentially spaced apart at each cross-directional position along a sensing roll of a nip press to measure and cancel or nearly cancel the effects of rotational variability which may be acting on the sensing roll. The strategically-placed sensors are designed to measure the pressure being placed against the web that is being advanced through the nip press. The average of the measurements of multiple sensors spaced circumferential apart provides a good cancellation of any rotational variability that might be found at a cross-directional position on the sensing roll. In this manner, a more true measurement of the nip pressure profile can be obtained and better adjustments made to reduce nip pressure profile variability. In addition, the nip variability profile may be used as a predictor of cover or bearing failures, resonant frequencies and other roll anomalies.
