A method for extracting resins and oils from a plant includes: 1) tumbling, inside a container at a temperature of at most 50 degrees Fahrenheit with a tumbler, plant fibers having one or more portions that contain resins and/or oils; 2) colliding the tumbler with the plant fibers to release the one or more portions that contain resins and/or oils from the remainder of the plant fibers; and 3) segregating the one or more portions that contain resins and/or oils from the remainder of the plant fibers.

An easily assembled blender with an internal frame holding a cupholder elevator assembly, a mix motor assembly, a food preparation chamber, a water heater assembly and a steamer assembly. The water heater and steamer assemblies are preferably on modular trays that slide into the internal frame. The water heater preferably also serves as a hot water reservoir and, to avoid overheating, has its heating coil located near its bottom. To resist scale deposits, polytetrafluoroethylene (PTFE) tubing is preferably used to transport steam from the steamer to the food preparation chamber. To expedite manufacture, a spring-biased idler assembly with a drive belt for the cupholder elevator assembly preferably snaps into a lower receiving port on the internal frame. Crisscrossing infrared light beams are preferably placed at the entrance of the food preparation chamber to detect whether the cup entering the chamber is the correct size and detect whether any foreign object is below the food preparation chamber.

A MEMS multiplexing system including: first and second fluid inputs; and a mixing network. The mixing network including: a first channel to receive the first fluid input; a second channel to receive the second fluid input; a multiplexing valve communicating with the first channel and the second channel, the multiplexing valve to cause the transport of the first fluid into the second channel so as to form a first interleaved fluid downstream from the multiplexing valve in the second channel and to cause the transport of the second fluid into the first channel so as to form a second interleaved fluid downstream from the multiplexing valve in the first channel; and the first channel and the second channel intersecting downstream from the valve so as to force mixing of the first interleaved fluid and the second interleaved fluid.

A method includes, under control of control circuitry implementing a mixing protocol, aspirating reagents from multiple different reagent reservoirs into a cache channel. Designated amounts of the reagents are automatically aspirated from the corresponding reagent reservoirs by corresponding sippers based on the mixing protocol implemented by the control circuitry. The method also includes discharging the reagents from the cache channel into a mixing reservoir, and mixing the reagents within the mixing reservoir to form a reagent mixture.

A mixing device includes a mixing container rotatable about a first axis of rotation for receiving mixing material, which has a mixer opening and a mixer cover which can be reciprocated between an opened position and a closed position. The mixer cover in the closed position closes the mixer opening and in the opened position exposes the mixer opening. The mixing container is rotatably mounted to a machine stand. The mixer cover is so fixed to the machine stand that the mixing container in the closed position of the mixer cover is rotatable relative to the mixer cover about the first axis of rotation. The machine stand has a stationary element and a pivotal element, wherein the pivotal element is mounted pivotably about a pivot axis relative to the stationary element. The mixing container is mounted rotatably to the pivotal element and the mixer cover is fixed to the pivotal element.

Various methods and systems are provided for mixing and dispensing viscous materials for the creation of additive structures. As one example, during a mixing and dispensing operation with a mixing and dispensing head of a multi-dimensional printing apparatus, linear movement of a mixing rod positioned within a mixing chamber of the mixing and dispensing head, at least along a central axis of the mixing chamber, is adjusted based on an operating condition of the printing apparatus and dispensing of mixed liquids from the mixing and dispensing head is stopped by stopping one or more pumps fluidly coupled to the mixing chamber and linearly moving the mixing rod upward and away from a dispensing nozzle of the mixing and dispensing head.

Various methods and systems are provided for mixing and dispensing viscous materials for the creation of additive structures. As one example, in a multi-dimensional printing apparatus, one or more materials flow into a mixing chamber via one or more corresponding inlet channels, a rotational speed of a mixing rod positioned within a mixing chamber is adjusted based on a volume of the mixing chamber and a flow rate of the one or more materials into the mixing chamber, the mixing rod including a set of straight cutaways extending along a length of a bottom portion of the mixing rod and forming flat side surfaces of the mixing rod; and a mixture of the one or more materials is dispensed from the mixing chamber via a dispensing nozzle of a mixing and dispensing head.

A carbonated beverage apparatus includes a freezing cylinder for receiving a mixture, and a stirring pusher disposed inside the freezing cylinder for pushing and mixing the mixture from an inlet of the freezing cylinder to an outlet thereof in a spiral manner, wherein the mixture is removed from the inner wall of the freezing cylinder radially back into a center portion of the freezing cylinder by the stirring pusher.

Mixers for adhesives and sealants that include automatic stroke length adjustment for different sizes and configurations of adhesive and sealant cartridges are disclosed. The mixers include a sensor for detecting when a mixing impeller reaches the top of a cartridge and the bottom of a cartridge, which sends a signal to a main pressure cylinder to reverse direction. The stroke length of the mixer is automatically adjusted without the necessity of manual selection based upon a particular cartridge size.

The present invention provides a method and system for providing on-site electrical power to a fracturing operation, and an electrically powered fracturing system. Natural gas can be used to drive a turbine generator in the production of electrical power. A scalable, electrically powered fracturing fleet is provided to pump fluids for the fracturing operation, obviating the need for a constant supply of diesel fuel to the site and reducing the site footprint and infrastructure required for the fracturing operation, when compared with conventional systems.
