Abstract: An automated gate actuator system is provided for use in selectively opening and closing a gate that dispenses proppant from a proppant container during the course of a hydraulic fracturing operation. A lever arm is pivotally mounted for movement to place a drive gear in contact with a driven gear to open and close the gate. The gate may be remotely or autonomously actuated in this manner utilizing an electronic control triggered by human and/or sensor input.

Abstract: Data account management systems and methods are described. A server is in communication with one or more information source systems, at least one user device associated with at least one user and one or more electronic data accounts associated with the user. The server links the electronic data accounts, monitors data among the information source systems and the linked accounts for any changes in activity associated with the user, predicts a behavioral activity of the user via machine learning based on at least one of the monitored data and historical data associated with the user, identifies at least one notification instruction specific to the user based on the predicted behavioral activity, and generates an interactive graphical user interface (GUI) for display on the user device. The interactive GUI presents one or more of the notification instruction and a user profile of the at least one user among the linked accounts.

Abstract: An Antenna Positioning System for missile seeker and system development and test comprises an antenna module, and a plurality of tethers, wherein the antenna module is suspended in a position by the tethers and the position is capable of being changed and the antenna module manoeuvred by pulling at least one tether and simultaneously releasing at least one tether. The system is useful for testing and developing Radio Frequency (RF) missile technology in a controlled, simulated environment rather than by live missile firings.

Abstract: A proppant container facilitates the transportation of wet sand for use in a hydraulic fracturing operation. The container is mounted in a cradle that tips downward in arcuate motion for discharge or proppant through a top opening The tipping mechanism may be driven by a system of gears or a hydraulic ram.

The container is mounted in a cradle that tips downward in arcuate motion for discharge or proppant through a top opening The tipping mechanism may be driven by a system of gears or a hydraulic ram.

Abstract: A proppant container facilitates the transportation of wet sand for use in a hydraulic fracturing operation. The proppant container is provided with a system for dislodging the wet sand for subsequent use. This may be done by use of a vibrator or an umbrella valve. In another aspect, the proppant container may be used in combination with a rack having a wash system that slurries the proppant for delivery to a blender tub without necessarily resorting to use of a conveyor belt.

Abstract: A proppant container facilitates the transportation of wet sand for use in a hydraulic fracturing operation. A metering conveyor is positioned between a blender tub and a proppant motive mechanism, such as a conveyor or wash system that receives discharge direct from proppant containers of the type normally used to transport sand in support of a hydraulic fracturing operation. The metering conveyor is fitted with equipment including an intermediate surge hopper with a vibration system and a knife-edge gate that may be used to facilitate the operational movement of sand.

Abstract: A conveyor sled assembly is utilized to supply proppant in support of oilfield hydraulic fracturing operations. The conveyor sled assembly includes precisely positioned components where tolerances between components are so small as to prevent significant spillage at component junction boundaries. This manner of fitting proppant pods onto the conveyor sled assembly increases predictability of which pods will discharge their proppant load first. This enhances reliability of the overall proppant delivery system.
