Abstract: A system for transporting a proppant for fracking may include a transport vehicle, a proppant container, a container clutch part, and a floating clutch part. The transport vehicle may include a carriage having forks for engaging fork pockets of the proppant container. The proppant container may house proppant releasable using a release gate and actuator. The container clutch part may be connected to the proppant container and configured to transfer rotational movement to the actuator. The floating clutch part may be connected to the carriage of the transport vehicle and configured to engage and selectively rotate the container clutch part when the forks engage the fork pockets. The forks and fork pockets vary in size which leads to a potential for misalignment between the container and floating clutch parts. The floating clutch part is vertically and laterally positionable to compensate for misalignments between the container and floating clutch parts.

Abstract: A method for loading a plurality of dynamically linked assemblies during the execution of an application program is disclosed. The application program reads a configuration file that includes a load sequence for the plurality of dynamically linked assemblies and a class associated with each dynamically linked assembly. The plurality of dynamically linked assemblies are loaded in accordance with the load sequence read from the configuration file. Each class has a common dataset and each of the plurality of dynamically linked assemblies is independent from the other of the plurality of dynamically linked assemblies. A process request defined by the associated class is sent to at least a first of the plurality of dynamically linked assemblies.

Abstract: A method of partitioning and archiving electrical data received from a power monitoring system in a database including a plurality of tables organized by at least group and date. Data in the database is queried by first searching an electrical data catalog to determine whether the data exists in the database before searching the database. The data is targeted by group and by date, yielding faster response times and enhanced database scalability. An electrical data retention table includes a set of rules governing, for each group, the maximum age of the data that can be stored in the table in the database. A data table associated with a particular group whose age exceeds the maximum age provided in the set of rules is removed from the database and from the electrical data catalog. If desired, the entire data table can be imported back into the database.
