A fuel pump for a liquid fuel water injection system of a motor vehicle is provided. The fuel pump includes a low-pressure pump that mixes water from a water tank of the motor vehicle with liquid fuel from a fuel tank of the motor vehicle to a liquid fuel water emulsion and provides the liquid fuel water emulsion at a low pressure. A high-pressure pump is in fluid communication with the low-pressure pump and compresses the liquid fuel water emulsion from the low pressure to a high pressure for injecting the liquid fuel water emulsion into an internal combustion engine of the motor vehicle via an injection rail of the motor vehicle. A pump drive drives the low-pressure pump and the high-pressure pump synchronously with a pump frequency independently from an engine speed of the internal combustion engine of the motor vehicle.

A novel canister storage system, mixing system, canister assembly, dispensing system, and tracking system. In one or more embodiments, the systems are used for storing, mixing and dispensing fluids. In one application, the fluid includes one or more paint toners.

This in-line active and reverse calculating mass balance blending system can maintain a chemical at desired control points, such as with respect to concentration, temperature, and/or pressure, while the output flow rate is changing dynamically to a point of use. A blending unit is configured to receive and blend at least two species and deliver a mixture at selected concentrations to points of use. A controller can be configured to determine a mass balance to maintain the concentrations in the mixture using information from metrology systems and a flow in an output to the at least one point of use. The controller also can be configured to maintain a concentration in the mixture within a concentration range by controlling flow rates to the blending unit.

In at least one embodiment, a system for a blender tub overflow catch is disclosed for fracturing operations using a fracturing fluid blender. In at least one embodiment, the system includes a first tub that may be a blender tub and a second tub forming a blender tub overflow catch that is adapted to circumvent an outside diameter of the first tub to catch overflow fluid from the first tub so that it can be directed back into the first tub upon a determination that the first tub has a capacity to handle the overflow fluid.

The invention provides a multi-compartment container for storing and dispensing separately a plurality of consumable liquids that can be mixed in an accurate and repeatable manner. Each storage compartment within the container encloses a predetermined quantity of a consumable liquid, wherein the first compartment is filled with a first liquid and the other compartments are filled with second and third liquids. The individual storage compartments are structurally merged to form elongated dispensing compartments each with a first end and a second end, wherein a one-way outlet positioned at the first end and a one-way outlet located at the second end permits passage of liquid from the storage compartments into the corresponding dispensing compartments. Upon fully inverting the container, the designated outlet of each dispensing compartment is opened, wherein precise amounts of liquids in the first, second, and third compartments are dispensed at constant volume ratio using gravity.

The present disclosure relates to use of specialized vessels for formulating and dispensing pharmaceutical formulations. The vessels are optionally able to maintain homeostatic conditions and a homogeneous constitution of pharmaceutical suspensions, while simultaneously dispensing them into single-use containers.
