The embodied invention is a low humidity generator which encapsulates essential piping, pressure regulator, flow regulator, and saturator in a sealed vacuum chamber. Additionally, a Stirling piston type cooler is used to cool the saturator. This eliminates atmospheric water vapor permeation and the need for thermal insulation surrounding the piping and control units. Also, the humidity generator has improved cool down characteristics, improved thermal control, and better maintenance access.

The aerator system incorporates a land-based or water-based floating solar activated water aeration system with integrated linear diaphragm air compressor and controller to provide improved oxygen addition into water. The system uses low voltage and an advanced controller with max power point tracking (MPPT) technique, which converts the solar panel photovoltaic low voltage DC to low voltage AC and allows power generated from each solar panel to be fully utilized.

An inline buffer dilution system is provided that includes a first flow control valve fluidly connected to a supply of diluent liquid, second and third flow control valves fluidly connected to supplies of a first buffer and a second buffer, respectively, and a mixing pump fluidly connected to the first, second, and third flow control valves and configured to mix an amount of the diluent liquid, the first buffer, and the second buffer to produce a diluted buffer solution. The system further includes a backpressure control valve configured to generate a backpressure that promotes mixing within the mixing pump, and a controller configured to control the backpressure based on the amount of the diluent liquid, the first buffer, and the second buffer being mixed in the mixing pump, such that the mixing pump yields a minimum mixing threshold across a range of fluid flows.

A beverage container has a body with an open top, an interior volume and a closed bottom. A lid assembly is removably coupled to the open top of the body. A storage compartment is removably coupled to the closed bottom of the body. A mixer is coupled to the lid assembly. The mixer can mix contents located inside the body. The mixer can be silent when a user of the beverage container shakes contents located inside the body.

Embodiments include systems and methods of in-line mixing of hydrocarbon liquids and/or renewable liquids from a plurality of tanks into a single pipeline based on density or gravity. According to an embodiment, a method of admixing hydrocarbon liquids from a plurality of tanks into a single pipeline to provide in-line mixing thereof includes initiating a blending process. The blending process including continuously blending two or more liquids over a period of time, each of the two or more liquids stored in corresponding tanks, each of the corresponding tanks connected, via pipeline, to a blend pipe thereby blending the two or more liquids into a blended liquid. The method further includes determining a density of each of the two or more liquids to be blended during the blending process. The method includes, in response to a determination that the blend process has not finished and after the passage of a specified time interval, determining an actual blend density of the blended liquid, via a blend sensor connected to the blend pipe, the blended liquid flowing through the blend pipe and in contact with the blend sensor, and the specified time interval less than a total duration of the blending process. The method includes determining an actual blend density of the blended liquid, via a blend sensor connected to the blend pipe, the blended liquid flowing through the blend pipe and in contact with the blend sensor, and the specified time interval less than a total duration of the blending process; comparing the actual blend density with a target blend density; and in response to a difference, based on the comparison, of the actual blend density and target blend density determining a corrected ratio based on each density of the two or more liquids, the actual blend density, and the target blend density and adjusting, via one or more flow control devices, flow of one or more of the two or more liquids, based on the corrected ratio.

An agitator device for mixing materials, including a containment vessel defining an interior volume, a hollow shaft having an upper end, a lower end, and a central bore along its length, the lower end extending downwardly into the interior volume of the containment vessel, the hollow shaft being rotatable with respect to the containment vessel, and a takeout tube having an upper end and a lower end, wherein the takeout tube is disposed within the central bore of the hollow shaft so that the lower end of the takeout tube is in fluid communication with the interior volume of the containment vessel.

The electric drill tool is attached to the drive shaft housing assembly. The gearbox transmission assembly is attached to the drive shaft housing assembly. The pair of mixing blades are attached to opposing shafts extending from the gearbox transmission assembly. The splash guard attached to the exterior the drive shaft housing assembly. The handle assembly is attached to the drive shaft housing assembly. The resulting tool can be used by a person to mix wet cement within a wheelbarrow or other similar open topped container.

The sealing performance of a stirring device and the abrasion resistance of a seal are improved. A stirring device includes a stirring tank that defines a stirring chamber; a plurality of stirring blades that are disposed in the stirring chamber; a shear blade drive shaft that extends from a lower side of the stirring tank to the stirring chamber and rotationally drives at least one shear blade among the plurality of stirring blades; and a fixed ring and a rotating ring that is disposed radially outside the shear blade drive shaft and seals between the stirring tank and the shear blade drive shaft. A sealing surface of the mechanical seal structure is formed at the same height as or above a lowermost portion of the stirring chamber.
