An apparatus and method for manufacturing an electricity storage material are provided which allow easily measuring the dissolution rate to solubility of a solution of a powder thickener dissolved in a liquid solvent. An apparatus for manufacturing an electricity storage material includes: a dissolving device that dissolves in a liquid solvent a thickener as powder that is ionized when dissolved; and a dissolution-rate-to-solubility determining device that measures conductivity of the solution produced by the dissolving device and determines a dissolution rate to solubility of the solution based on the measured conductivity. The dissolution rate to solubility can thus be determined without the need to stop the dissolving device during dissolution of the thickener in the liquid solvent. This can significantly improve production efficiency. Since excessive operation of the dissolving device can be prevented, energy saving can be achieved.

A system and method of wellbore operations that uses an eductor unit for introducing additives into a moving fluid stream to form a mixture. The mixture is used as a completion drilling fluid for drilling through plugs installed in a wellbore. Example additives include polymers, such as friction reducers, viscosifiers, potassium chloride, polysaccharide, polyacrylamide, biocides, lubricants, long chain polymer molecules, and the like. The fluid is primarily fresh water and/or brine water, and acts as a motive fluid in the eductor unit for drawing the additive into the eductor unit. Forming the mixture in the eductor unit which is injected into the wellbore.

A method is provided for monitoring a flow behavior of mixed components without requiring additional instrumentation or sampling. The method is carried out by determining ratios of the power required to rotate a mixing impeller at different rotational speeds and then comparing the ratios. Characteristics about the mixed components are determined based on differences between the ratios.

Viscosity and other properties are determined at desired temperatures in drilling mud and other fluids by using a versatile cavitation device which, operating in the cavitation mode, mixes and heats the fluid to a specified temperature, and, operating in the shear mode, acts as a spindle for application of Couette principles to determine viscosity as a function of shear stress and shear rate. The invention obviates the practice of adjusting rheology of a drilling fluid by passing it through the drill bit. Drilling fluid may be managed by a “straight-through” method to the well, or by placing the cavitation device in a loop which isolates an aliquot of known volume and circulating the fluid through the loop including the cavitation device. A controller may be programmed to manage the viscosity and other properties at various temperatures by controlling the power input and angular rotation of the “spindle” (which has cavities on its cylindrical surface), and feeding viscosity-adjusting agents and other additives to the fluid. Data may be collected from the loop and used in the “straight-through” mode until it is determined that conditions require a new set of data, or the loop may be used continuously. The system may be used with a supplemental viscometer, density meter, and other instruments.

Assembly for dispensing a liquid, in particular a colorant for paint, comprising a container for holding a liquid, a pump, a valve, at least one dispense opening, and comprising or associated with a controller arranged to operate the pump and the valve to withdraw liquid from the container and to dispense liquid via the opening and to operate the pump and the valve to purge liquid from the pump to the container via the dispense opening.

A closed-loop drilling fluid condition system for drilling fluid mixing and recycling process is described. The closed-loop drilling fluid condition system improves drilling fluid quality, repeatability, utilization efficiency, and health, safety and environment (HSE) issues. In particular, the closed-loop drilling fluid condition system automates a water-based drilling fluid workflow or an oil-based drilling fluid workflow where individual stages are monitored and adjusted in real-time. Specifically, the individual stages are monitored in real-time using sensors and adjusted in real-time based on commands from a monitoring device to achieve specific drilling fluid parameters.

A preparation apparatus includes a first tank, a second tank, a preparation tank, and a computer having a hardware processor. The first tank contains a first liquid. The second tank contains a second liquid having a lower viscosity than the first liquid. The preparation tank stirs the first liquid supplied from the first tank and the second liquid supplied from the second tank to prepare a preparation liquid. The hardware processor measures a viscosity of the first liquid based on a supply time required to supply a specified amount of the first liquid at a constant pressure from the first tank to the preparation tank, and supplies an amount of the second liquid to the preparation tank based on the measured viscosity of the first liquid so as to cause the preparation liquid to have a target viscosity.

The disclosure relates to a labelling machine for applying labels onto containers using cold glue, comprising a glue supply device. The glue supply device is configured to produce the cold glue from several components, in particular at least one liquid and one solid component, so that the cold glue required for applying the labels can be produced by processing the components, in particular mixing them together.

A computer-implemented method and a computer-based product and monitoring system for contactless assessment of rheological properties of a fluid cement-based product, the method performing a first analysis which obtains the rotation speed of the mixing blades (31) of a truck-mounted concrete mixer drum (30) and detects the variation of the speed constituting a first parameter, performing a second analysis which obtains at least a sequence of images of the fluid product contained within the mixer drum (30), identifies particles, shapes, groups of particles, contours, and/or slope of the fluid product within the collection of sequential images, detects variations of speed and displacement direction of the particles and shapes, constituting a second parameter, performing a third analysis that detects a correlation between each first and second parameters from which the system calculates at least one parameter of rheological properties of the fluid product.

A system features an acoustic sensor configured to mount on a wall of a mixing drum, sense an acoustic characteristic of a mixture of a slurry, including concrete, contained in a mixing drum when rotating, and provide acoustic sensor signaling containing information about the acoustic characteristic sensed; and a signal processor configured to receive the acoustic sensor signaling, and determine corresponding signaling containing information about a slump characteristic of the mixture of concrete contained in the mixing drum, based upon the signaling received.
