Abstract: Systems and techniques are provided for processing a high oil concentration feedstock, particularly a hemp feedstock, to extract oil from the feedstock. In some examples, the feedstock is processed by flaking the hemp feedstock followed by solvent extraction. The hemp material may be introduced between rotating flaking rolls to flake the hemp heart feedstock. According to some examples, the speed and/or spacing of the flaking rolls may be controlled to control the characteristics of the resulting flaked hemp material for subsequent solvent extraction. Extraction performance of the hemp feedstock can vary based on the characteristics of the flake properties dictated by controlling the flaking rolls.

Abstract: A liner for a folding knife includes a curved elongated spring to bias a blade of the knife to an open or closed position. The spring may extend in an arc from an origination point to a free end, within a cutout region of a body of the liner. The spring may be J-shaped in one approach. The spring may be integrally formed with the liner or formed as a separate piece which is attached to the liner. The free end may include a shoe to contact a lock stud in a handle of the knife. The origination point may be below and frontward of the shoe. The spring biases the lock stud frontward to lock the blade in the open position. To close the blade, the user moves the lock stud rearward, against a spring force of the spring, allowing the blade to rotate to the closed position.

Abstract: An oil extraction process may be performed on an oleaginous feedstock using an alcohol-based solvent, such as ethanol. In some examples, an extraction process involves conveying a material in countercurrent direction with an alcohol-based solvent to generate an extracted material and a miscella. The miscella stream is cooled to form a first solvent-rich layer phase separated from a first oil-rich layer, which is then separated to form a first separated oil-rich stream and a first separated solvent-rich stream. In some examples, the first separated solvent-rich stream is recycled back to the extractor and introduced into the extractor at a location different than a location where fresh solvent is introduced into the extractor. Additionally or alternatively, water may be introduced into the separated first oil-rich stream to form a second solvent-rich layer phase separated from a second oil-rich layer, which is then separated to form a second separated oil-rich stream.

Abstract: The present disclosure is directed to systems, apparatuses, and methods for controlling an electrical system using setpoints. Some embodiments include systems that receive a meter read schedule comprising anticipated meter read occurrences. The systems may set a demand setpoint representing a desired upper limit of demand of the electrical power system and adjust the demand setpoint during a billing period. The system may also reset the demand setpoint multiple times at different reset points around each of the anticipated meter read occurrences.

Abstract: Devices, systems, and techniques can be provided for processing an oil-containing material with an alcohol-based solvent to extract oil from the material. In some examples, a system includes an extractor configured to process an oil-containing feedstock. The extractor receives the oil-containing feedstock and conveys the material from an inlet to an outlet through the extractor. The extractor also receives an alcohol-based solvent at a solvent inlet and conveys the solvent through the extractor to a solvent outlet. The alcohol-based solvent may be ethanol. A concentration of oil in the feedstock may decrease as the feedstock moves through the extractor from the inlet to the outlet while the concentration of the oil in the solvent increases.

In some examples, an extraction process involves conveying a material in countercurrent direction with an alcohol-based solvent to generate an extracted material and a miscella. The miscella stream is cooled (14) to form a first solvent-rich layer phase separated from a first oil-rich layer, which is then separated (18) to form a first separated oil-rich stream (100) and a first separated solvent-rich stream (102). In some examples, the first separated solvent-rich stream is recycled back to the extractor and introduced into the extractor at a location (38) different than a location (30) where fresh solvent is introduced into the extractor.
