A liquid extractor may include an extraction chamber containing a bed deck configured to support a solid material as the solid material is conveyed through the extraction chamber. To introduce solvent into the solid material being processed, the extractor may include a solvent injection orifice extending through the bed deck and a solvent injector. The solvent injector can receive solvent from a source and cause the solvent to rotate within the solvent injector before discharging the solvent through an outlet in fluid communication with the solvent injection orifice. The rotational flow motion imparted by the injector can create a vortex that functions to scout out any particles that may be present in the injector.

A protection circuit is disclosed. The protection circuit includes a direct current (DC) blocking component electrically connected between a neutral of the transformer and a ground, and an overvoltage protection device electrically connected in parallel with the DC blocking component. The overvoltage protection device is constructed to repeatably and reliably provide overvoltage protection in response to a voltage at the transformer neutral above a threshold. The DC blocking component has an impedance below a predetermined value, thereby effectively grounding the neutral of the transformer. The DC blocking component is persistently maintained in connection to the transformer neutral.

A desolventizer for processing solvent-wet solid material may include a thermal recirculation loop to increase thermal performance. In some examples, the desolventizer includes a housing, an ejector, and a vent. The housing contains a first tray and a second tray vertically elevated above the first tray to define a processing space. The ejector has an inlet located between the first tray and the second tray and an outlet also located between the first tray and the second tray. The vent has an inlet located between the first tray and the second tray. In operation, the ejector can draw gas from the processing space via the inlet and discharge the gas through the outlet back into the processing space, creating a recirculation loop.

The present disclosure relates generally to an overvoltage protection assembly, and an electrode useable in pairs in such an overvoltage protection device. In various aspects, at least one electrode is made from a single piece of conductive source material to ensure its strength, reliability, and ease of manufacture. Still further, the electrode has a specific geometry selected to enhance electromagnetic effects experienced during high voltage, high current overvoltage events in a way that quickly relocates and dissipates an arc formed at a gap between an electrode pair, to ensure repeatable, reliable performance of the overvoltage protection device.

Overvoltage protection assembly

Electrical protection devices, such as for use with power systems for overvoltage protection, are disclosed. One electrical protection device includes a first electrical connection, a second electrical connection, a first electrical discharge device, and a second electrical discharge device. The first electrical discharge device includes a first conductive bus connected to the first electrical connection and a second conductive bus connected to the second electrical connection. The first electrical discharge device has a first breakdown voltage. The second electrical discharge device includes a third conductive bus connected to the first electrical connection and a fourth conductive bus connected to the second electrical connection. The second electrical discharge device has a second breakdown voltage.

Overvoltage protection for power systems

An extraction system may include a primary extractor that is configured to process a main feedstock undergoing extraction and a secondary extractor configured to process particulate matter separated from miscella produced on the primary extractor. In some configurations, the secondary extractor is an immersion extractor that has a solvent stream flowing in a counter current direction to a direction which the particulate matter flows through the extractor. In operation, the primary extractor can generate a miscella stream containing solvent and components extracted from the feedstock being processed by the extractor. Following separation in which the miscella stream is processed to remove particulate matter, the particulate matter may be charged to the secondary extractor as a feedstock for the secondary extractor. In some examples, the miscella from the primary and secondary extractors are combined and/or the discharged feedstock from the primary and secondary extractors are combined for subsequent processing.

Methods and systems for ensuring operation of one or more circuit breakers electrically connected on a phase of a multi-phase power line on a transformer electrically connected within a power grid at a substation are disclosed. The method includes detecting, at the transformer, a direct current component of a multi-phase power signal received at the transformer, the direct current component comprising a direct current received at a transformer neutral, the transformer neutral being electrically connected to a ground. The method further includes determining whether the direct current is above a predetermined threshold, the predetermined threshold being based on a determination that, above the predetermined threshold, at least one of the one or more circuit breakers is incapable of reliable operation. The method includes, in response to a determination that the direct current component is above the predetermined threshold, blocking the direct current between the transformer neutral and a ground.

An immersion extractor may have a housing that maintains a solvent pool in which solids material being processed is immersed during operation. One or more bed decks can be positioned inside of the housing to provide multiple extraction stages. In some examples, a final bed deck extends from below a solvent level maintained in the housing to above the solvent level such that solids material is conveyed out of the solvent pool and toward a feed outlet at the end of extraction. The bed deck may include a drainage section positioned between the top of the solvent level in the extractor and the feed outlet, allowing solvent to drain out of the solids material before being discharged through the feed outlet, thereby increasing the efficiency of the extraction process.

Extractor having a solvent drainage zone

An extractor may have a housing that maintains a solvent pool in which solids material being processed is immersed during operation. One or more bed decks can be positioned inside of the housing to provide multiple extraction stages. In some examples, the bed decks are arranged to provide one bed deck positioned at a vertically elevated position relative to another bed deck, thereby providing a drop zone where the solids material passing through the machine drops from the vertically elevated bed deck to a lower bed deck. To reduce the amount of solids material passing through the drop zone that becomes entrained in the solvent, the exactor can be configured with a settling zone. In some examples, the settling zone is formed by truncating the length of the vertically elevated bed deck, providing increased space and residence time for the solids material to fall out of suspension.

Extractor with settling zone near solvent discharge

An extractor can be used to extract solvent-soluble molecules, such as aqueous or organic-soluble molecules, from solid material feedstock for downstream processing and recovery. In one configuration, the extractor is a percolation extractor having one or more extraction chambers each containing a screen supporting the solid materials as it is conveyed through the chamber, a fluid supply system delivering extraction fluid disposed above the solid material, and a fluid recovery system disposed below the solid materials for receiving the extraction fluid and solvent-soluble molecules contained therein. The extractor further includes a screen washing system disposed under the screen and supported against movement. The screen washing system includes a washing fluid intake and a plurality of outlet nozzles directed upward towards the screen. The screen washing system can keep the screen from plugging during operation, improving the extraction efficiency of the extractor.

Methods and devices for shielding electronic equipment within an enclosure are disclosed. One method includes positioning electronic equipment within an interior volume of a shielding enclosure having an opening providing access to the interior volume, the opening surrounded by an enclosure frame. The method further includes closing a door to the shielding enclosure, thereby closing off the opening, and engaging one or more latches to affix the door in a closed position, the door including a shielding curtain positioned across the opening. The method also includes inflating an inflatable member positioned along a perimeter of the door frame, thereby applying a uniform pressure to the shielding curtain toward the enclosure frame to form a seal therebetween.

A gearbox comprises a gearbox housing containing a gear train whose shafts are supported by the housing. The housing is fastened to a mounting plate at exactly three attachment points. This three point attachment reduces distortion of the housing that may cause misalignment of individual meshing gears in the gear train, leading to premature failure of those gears transmitting high torque.

A bearing assembly can be used in liquid service applications where the bearing assembly is intermittently or continuously exposed to liquid, such as below the liquid level of a solid-liquid extractor. In some examples, the bearing assembly includes an annular sleeve and an annular bearing. The annular sleeve is designed to be installed over the end of a rotatable shaft and positioned inside of a housing through which the rotatable shaft at least partially protrudes. The annular sleeve has an outer surface and length parallel to the rotational axis of the rotatable shaft. The outer surface of the annular sleeve may taper radially inwardly along at least a portion of the length of the sleeve. As a result, the bearing assembly and rotatable shaft positioned therein may pivot within housing about the taper of the annular sleeve.
