    Abstract: Embodiments described herein include an acoustic telemetry system for use with an apparatus configured to rotate. The acoustic telemetry system includes one or more sensor nodes and at least one receiver node. In at least one embodiment, the telemetry system also includes at least one hub node positioned on the apparatus. Each sensor node is attached to or embedded in the apparatus. Each sensor node obtains data related to one or more operating conditions of the apparatus and the environment surrounding the apparatus. The one or more sensor nodes encode and transmit the data to the hub node or the receiver node using ultrasonic acoustic waves. In at least one embodiment, the hub node transmits the data to the receiver node. The receiver node decodes the data and monitors the one or more operating conditions of the apparatus.

    Abstract: A method of assigning an octane number to a sample fuel based on the knock intensities obtained from a plurality of reference fuels each having a different assigned octane number while operating an engine at an established compression ratio. The knock intensities obtained from the plurality of reference fuels are plotted relative to the assigned octane numbers of the fuels. A line is fit to the plotted knock intensities. The octane number for a sample fuel is assigned based on the knock intensity obtained for the sample fuel, the knock intensity obtained from a prototype fuel having an assigned octane number, and the fitted line. In embodiments, an R squared value is obtained for the fitted line and compared with a minimum acceptable R squared value and the fitted line is validated if the R squared value is at least the minimum acceptable R squared value.

    Abstract: A system for preparing a dry process material includes a sealed container that holds and seals the dry process material therein and prevents airborne dust or particles from the dry process material from escaping the sealed container. Sealed processing equipment receives the dry process material from the sealed container and prevents the airborne dust or particles from escaping the sealed processing equipment. A sealed connection sealingly couples the sealed container to the sealed processing equipment and prevents the airborne dust or particles from escaping while transferring the dry process material. A sealed transfer conduit is sealingly coupled to and extends from the sealed processing equipment.

    Abstract: A method and apparatus for identifying non-elastic indicators for a subsurface region, the method including obtaining seismic data for the subsurface region; generating a best-fit elastic model from the seismic data; and identifying non-elastic indicators from the seismic data and the best-fit elastic model. The method and apparatus may also include estimating reservoir flow properties from the non-elastic indicators based on a poroelastic interpretation of the seismic response. The method and apparatus may also include subdividing the seismic data into a plurality of subdivisions, wherein: generating the best-fit elastic model from the seismic data includes generating an individual best-fit elastic model for each subdivision; identifying non-elastic indicators from the seismic data and the best-fit elastic model includes identifying individual non-elastic indicators from each subdivision and its respective individual best-fit elastic model; and estimating the reservoir flow properties from the non-elastic indicators comprises analyzing the individual non-elastic indicators based on the subdivisions.
