  • Publication number: 20240068344
    Abstract: A blender power unit (BPU) for use in fracturing jobs. The BPU comprises a transformer having an input and an output and configured to receive electrical power via the input at a first voltage to output electrical power via the output at a second voltage; a motor power bus coupled to the output of the transformer; a motor starter bus; at least one motor soft starter having an input coupled to the motor power bus and having an coupled to the motor starter bus; a plurality of electric power relays coupled to the motor power bus and configured to supply electric power from the motor power bus to a load when in a closed state; and a plurality of start electric power relays coupled to the motor starter bus and configured to supply electric power from the motor starter bus to a load when in a closed state.

  • Patent number: 6131087
    Abstract: A computer implemented method for market participants for automatically identifying and matching offer data with solicitation data, the solicitation data stored in a solicitations data base, the method comprising the steps of: receiving offer data consisting of numerical linear ranges defining a lower point, an upper point, and a preferred point for each dimension of the offer data storing the received offer data in a database; comparing points for each dimension of the stored offer data to corresponding dimensions of the solicitation data to: identify solicitations with matching preferred points, identify solicitations with preferred points having a near match with the offer data when the upper point and the preferred point of the offer data are between the upper point and the preferred point of the solicitation data, and identify solicitations with preferred points within corresponding ranges to the offer data when at least one of the lower point, the upper point, and the preferred point of the offer data i

  • Patent number: 4332979
    Abstract: Systems analysis approach to measure and to reconstruct the sound energy flux distribution characteristic of "live" situations. The present invention relates to a method of measurement of acoustical fields and the functional relationships in audio systems for enhancing the reproduction of sound. The environmental acoustic simulator is a system which generates at least two signals having different combinations of time delays from each of a stereo input signal pair and for deriving therefrom a set of not less than four output channels. At least forty five time delays at nonuniform intervals spanning a time period of not less than two seconds with different frequency equalizations are derived. Diffuse sound fields are created through electronic mixing and by the employment of not less than four loudspeaker groups.
