Abstract: A dielectric assembly solid dielectric elements within a liquid or solid matrix material. The dielectric assembly may be manufactured by pressing a dielectric powder to form pressed dielectric elements, sintering the pressed dielectric elements to form the solid dielectric elements, and assembling the solid dielectric elements within the matrix material to form the dielectric assembly. The solid dielectric elements can be specifically oriented (e.g., in one or more tiled layers) or randomly oriented, and the dielectric assemblies can be molded and/or machined into desired 3D geometries. The dielectric assemblies can be relatively large (e.g., >1 mm3) while having bulk dielectric constants higher than conventional slurries and composites formed of dielectric powder in a liquid or solid matrix.

Abstract: A system for mixing acid and water can include a tank for holding acid, an acid pump for pumping acid out of the tank, an acid flow meter, an acid control valve, a water pump for pumping water, a water flow meter, a water control valve, a flush valve to selectively flush the system with water, and a controller to monitor the flow meters and control the pumps and the valves. The acid control valve and/or the water control valve can be an electronically controlled valve. The flush valve can be an electronically controlled valve to selectively permit water to flow from downstream of the water pump to upstream of the acid pump. The acid control valve, the water control valve, the flush valve, or any combination thereof can be throttled by the controller to control flow therethrough.

Abstract: Implementations are directed to aspect(s) of a fast feedback control system that actively stabilizes a geographically dispersed power grid by e.g., providing capabilities to match supply and demand at a high update rate. Implementations enable fast measurements of properties of the power grid and fast control parameter(s) back to controllable resource(s) in the power grid, such as control parameter(s) back to battery storage units, solar generation curtailment, wind generation curtailment, EV charging systems, and/or HVAC systems. In various implementations, the fast measurements and/or the fast control parameters can continuously occur at an update rate that is faster than once per second, such as at an update rate greater than 10, 20, 30, 40, 50, or 60 Hz. For example, measurements from a controllable resource can be transmitted to a geographically remote parent controller at 60 Hz and responsive control parameters can be received at the controllable resource at 60 Hz.

Abstract: Using real or estimated power measurements to detect one or more anomalies in an AC electric network. In some implementations, one or more actions can be automatically performed in response to detection of the anomaly. Such action(s) can include causing automatic control of electrical resource(s) of the AC electric network to mitigate the detected anomaly/anomalies. For example, such action(s) can include automatically isolating the AC electric network in response to detecting the AC electric network has one or more anomalies, and optionally restoring the AC electric network after the abnormal conditions are no longer detected. For instance, this can include a main AC electric network isolating an AC electric subnetwork in response to detecting abnormal conditions in the AC electric sub-network or an AC electric sub-network isolating and islanding itself from the main AC electric network in response to detecting abnormal conditions in the main AC electric network.

Abstract: Methods, systems, and controllers for detecting and mitigating well screen outs may include a controller configured to operate a fracturing pump to supply fluid at a discharge rate to a wellhead at a fracturing well site. The controller may also operate a blender positioned to deliver a blend of proppant and fluid to the fracturing pump. The controller may compare a fluid pressure increase rate to a preselected increase rate indicative of a potential well screen out. The controller may incrementally decrease the discharge rate of the fracturing pump and a flow rate of a blender when the fluid pressure increase rate of the wellhead exceeds the preselected increase rate and the fluid pressure is within a preselected percentage of a maximum wellhead pressure until the fluid pressure of the fluid supplied to the wellhead is stabilized.

Abstract: A fluid flow turbine blade assembly for a turbine rotor includes a blade and a deflector extending spanwise along at least a portion of the blade. At least a portion of an upstream surface of the deflector, along at least a portion of a span of the deflector, has a concave shape in a chordwise direction such that at least a portion of a chord line between leading and trailing edges of the deflector is disposed outside a profile defined between the upstream surface and a downstream surface of the deflector. The deflector has a substantially uniform thickness or a chord-wise varying thickness between the upstream surface and the downstream surface. The deflector alters fluid flow over the blade so as to increase the blade's contribution to global torque generated by the assembly so that, with the deflector's torque contribution, the global torque of the assembly is greater than the global torque that would be generated by the blade alone without the benefit of the deflector.

Abstract: A flexible coupling for a drive train, the coupling having a drive yoke, a driven yoke, and a connector for transferring rotational torque between the yokes. The drive and driven yokes are manually inserted into slots in the connector. The drive yoke connects to a drive shaft and the driven yoke connects to a driven shaft. Rotating the drive shaft rotates the drive yoke against the connector causing it to rotate; which in turn transfers torque to and rotates the driven yoke. Surfaces on the yokes and connector that contact one another during rotation define contact surfaces. Portions of the yokes and/or connector having the contact surfaces are obliquely profiled so that contact surfaces on the yokes are complementary to corresponding contact surfaces on the connector, which increases the areas of force transfer between the yokes and connectors.

Abstract: The data transformation method operates discrete input data sources DF-in each having df-in data fields carrying to-be-converted data (tbc-data). Initial steps identify tbc-data field and characteristics; output discrete output (df-out) with predefined df-out data fields for converted data (conv-data); and maps or look-up tables for relationships between df-in data fields and df-out data fields. Process activates: SFTP App in the presence df-in and transfers df-in to unstructured data blob; and App copying the df-in from blob to file share archive; first orchestrating sequence App to validate df-in data based upon conversion rules. If INVALID, App generates error entry. If VALID, App converts tbc-data into conv-data with conversion rules and mapping orchestrating App populates df-out data fields with conv-data resulting converted df-out in the blob. A second orchestrating App transfers converted df-out to destination store.
