摘要:
A power station includes a wedge-shaped body including first and second surfaces extending between respective first and second ends. The respective first ends meet with the respective second ends being spaced apart in a rest position. The first and second surfaces are biased apart from each other such that an outward force is generated thereby when urged together from the rest position. At least one power socket is located on the wedge-shaped body and configured for connection to an electrical power source.

The method and system quantify the impact of various design and operational solutions for equipment modules of a structure and the overall structure based upon economic factors. In particular, the method and system provide cost evaluation of various maintenance approaches for at least one equipment module that is part of an overall structure. In addition, a baseline and alternate equipment module may be specified for each equipment module. The costs associated with each of the maintenance approaches for each baseline and alternate equipment module then may be compared and the costs associated with the overall structure having a chosen maintenance approach for each baseline and alternate equipment module may be evaluated. The sensitivity of the costs associated with the overall structure to changes in one or more of the parameter values also may be calculated.

This invention relates to a turbine for extracting energy from an oscillating working fluid. The turbine includes a housing defining a flow passage for the working fluid. An energy conversion unit is disposed in the housing. Flow control means is selectively movable to occlude a predetermined portion of the flow passage such that the working fluid is directed to act on a certain section of the energy conversion unit.

Embodiments of machines, systems, computer-implemented methods, and computer program products certify oil and gas well equipment. Embodiments identify a selected well equipment device, a device test specification, and testing sequences to be performed by a corresponding testing apparatus. Embodiments select a testing sequence responsive to the selected device. Embodiments control the testing apparatus for the selected testing sequence so that the corresponding testing apparatus performs the sequence responsive to the device test specification. Embodiments generate testing data for the selected testing sequence and link the testing data for the selected testing sequence to the device identifier for the device so that a certificate can be generated. Embodiments generate a certificate for the selected device responsive to the testing sequences having been performed upon the selected device and link the certificate for the selected device to the device identifier so that the certificate can be readily recalled.
摘要:
A method and system for controlling fuel in a gas turbine engine including a fuel supply system channeling fuel to a combustor are provided. The system includes a first heat exchanger configured to transfer heat between a working fluid and a first cooling medium. The system also includes a second heat exchanger in series flow communication with the first heat exchanger wherein the second heat exchanger is configured to transfer heat between the working fluid and a second cooling medium. The system further includes a modulating valve configured to control the flow of at least one of the first and the second cooling media to maintain a temperature of the first or second cooling medium substantially equal to a predetermined limit.
摘要:
Aqueous textile treating compositions containing both nitrogen-functional organopolysiloxanes and oligomeric polyisobutylene polymers are as effective as conventional textile treating compositions containing only nitrogen-functional organopolysiloxane, and have improved resistance to yellowing, improved washfastness, and are more cost effective. Stable concentrates containing amino-functional organopolysiloxane, polyisobutylene, and a blend-stabilizing surfactant may be used to form aqueous emulsion and microemulsion fabric softener compositions.

An improved ocean wave energy extraction system is disclosed. The system includes at least one duct for receiving an oscillating water column. The duct has a first segment, a second segment arranged transversely to the first segment and a flow control segment intermediate the first and second segments. The flow control segment is configured to inhibit turbulent flow of the oscillating water column flowing within the duct. A turbine is in fluid communication with the second segment of the duct such that the turbine is driven by the fluid flow which is generated by the oscillations of the oscillating water column within the duct. The turbine rotates an electric generator to thereby generate electrical energy.

A tape containing an unbalanced woven fabric and an adhesive. The woven fabric has a warp dominant face and a filling dominant face, a plurality of warp yarns in a warp direction, and a plurality of filling yarns in a filling direction perpendicular to the warp direction crossing with the warp yarns at a plurality of intersections. At least 55% by number of the intersections have the warp yarn crossing with the filling yarn such that the warp yarn is on the warp dominant face of the fabric. At least 55% by number of the intersections have the warp yarn crossing with the filling yarn such that the filling yarn is on the filling dominant face of the fabric. The warp yarns have a linear mass density of between about 30 and 100 denier and the filling yarns have a linear mass density of between about 70 and 600 denier.
