Embodiments include systems and methods of in-line mixing of hydrocarbon liquids from a plurality of tanks into a single pipeline. 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 determining a ratio of a second fluid flow to a first fluid flow based on signals received from a tank flow meter in fluid communication with the second fluid flow and a booster flow meter in fluid communication with a blended fluid flow. The blended fluid flow includes a blended flow of the first fluid flow and the second fluid flow. The method further includes comparing the determined ratio to a pre-selected set point ratio thereby to determine a modified flow of the second fluid flow to drive the ratio toward the pre-selected set point ratio. The method further includes controlling a variable speed drive connected to a pump thereby to control the second fluid flow through the pump based on the determined modified flow, the pump being in fluid communication with the second fluid flow.

The present invention relates to a dispensing system (10) comprising an assembly having a dispenser (11) of at least one cosmetic product, in particular makeup, and having at least two outlet interfaces (110), each of which can be mounted removably on the dispenser, the dispenser having at least two different base products and allowing these to be delivered in variable proportions, the outlet interfaces being able to receive the one or more products delivered by the dispenser.

A solenoid valve includes a main valve, a first auxiliary valve, a second auxiliary valve, a main valve body, and an auxiliary valve body. The main and auxiliary valve bodies are axially parallel and detachably connected. The main valve is mounted on the main valve body, the first and second auxiliary valves are mounted on the auxiliary valve body, which is provided with an air inlet, a cylinder port and an air discharging port. The air inlet communicates with the main valve through a first air passage. The cylinder port is sequentially in communication with the first and second auxiliary valves and the main valve through a second air passage. The air discharging port sequentially communicates with the first and second auxiliary valves and the main valve through a third air passage. The main and second auxiliary valves are solenoid valves. The first auxiliary valve is a hand-operated valve.

Glycine is an organic compound that can be used in the making of a synthetic acid that obviates all the drawbacks of strong acids such as hydrochloric acid. The new compound is made by dissolving glycine in water, in a weight ratio of approximately 1:1 to 1:1.5. The solution is mixed until the glycine is essentially fully dissolved in the water. Once dissolution is complete, hydrogen chloride gas is dissolved in the solution to produce the new compound, which can be referred to as hydrogen glycine. Also disclosed is a method for adjusting the pH of a fluid, the method comprising adding an effective amount of a solution to the fluid for adjusting the pH thereof to a desired level, wherein the solution is prepared by mixing glycine in water to form a glycine solution; and adding hydrogen chloride to the glycine solution.
