Systems and methods for blending fluids are provided. A blended fluid may be obtained by mixing a first fluid from a first fluid source with a second fluid from a second fluid source. The blended fluid may be pumped by a pump arranged downstream of a point at which the first and second fluids are mixed, wherein no other pumps are upstream of the pump. First and second flow control valves that control the flow rate of the first and second fluids, respectively, are adjusted so as to reach a target flow rate of the blended fluid, the blended fluid having a target blend of the first fluid and the second fluid.

A device and a method for mixing a fluid in a specimen bag is provided herein. In one embodiment, the device includes a mechanism for creating a first vortex and a second vortex. The first vortex is on a first side of a bag containing the fluid, and the second vortex is on a second side of the bag. The mechanism includes a first inflatable airbag and a second inflatable airbag. The first inflatable airbag is configured to create the first vortex when inflated and the second inflatable airbag is deflated. The second inflatable airbag is configured to create the second vortex when inflated and the first inflatable airbag is deflated.

The present invention relates to a device (60) for manufacturing pharmaceutical compositions, comprising: a support (62); a mixing container (16); a plurality of reservoirs (18, 20) containing starting materials for the composition of a medicament; at least one dispensing device (64, 66) that is designed to dispense an amount of a starting material into the mixing container, wherein the dispensing device is assembled, or is designed to be assembled, with a reservoir; a stirring device (68) that is able to stir the mixing container and/or the contents of the mixing container; and an electronic module (74) for controlling the at least one dispensing device.

The present invention relates to an apparatus for producing a fuel made by mixing water with oil in a vacuum state. The apparatus includes: a vacuum tank adapted to seal an internal space thereof to allow the internal space to be maintained to a vacuum state; a vacuum pump located on one side of the vacuum tank to suck the air from the interior of the vacuum tank, so that the vacuum tank is kept in the vacuum state; a stirring vessel located inside the vacuum tank in such a manner as to communicate with the vacuum tank through a bypass pipe, the water and oil being supplied thereto; and stirrers rotating by the drive of motors to stirringly mix the water with the oil.

The present disclosure provides a fracturing fluid mixing equipment including a clear water supply system, at least two mixing systems, at least one powder tank, at least two powder conveying systems, a mixing tank, a feeding system and a power system. The clear water supply system has two parallel water supply paths which are connected to the mixing system and the mixing tank respectively. The powder conveying system is connected to the powder tank. There are same number of powder conveying systems and mixing systems which are connected in one-to-one correspondence. The mixing system is connected into the mixing tank. The feeding system adds powder by pneumatic conveying. The power system provides driving force by pure electric power and/or electro-hydraulic power. According to present disclosure, the power system can reduce fuel consumption and exhaust emissions. The feeding system can be compatible with various adding conditions of powders in different packaging, which can reduce the possibility of dust pollution, thereby reducing labor costs and occupational injuries and being more efficient and environmentally friendly.

Systems and methods for processing one or more waste fluids by measuring one or more properties of a waste fluid and adjusting the flow and/or flowability of the waste fluid based on the measurement are disclosed. The one or more properties of the waste fluid can include a viscosity of the waste fluid, a pressure of the waste fluid, and/or or a difference in pressure of the waste fluid. Adjusting the flow and/or flowability of the waste fluid can include adjusting the one or more properties of the waste fluid and/or affecting the direction of flow of the waste fluid in a manner which changes the destination of the waste fluid.

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.

An open-topped drinking cup and a lid comprising a lid cover and a mixing device for holding and mixing a condiment into a beverage held in the dinking cup. The lid cover defines a circular mounting aperture within which the mixing device is displaceably located. The mixing device includes at least two mixing elements which are connected to another so as to be telescopically displaceable relative to one another between a retracted condition and an extended condition wherein the mixing device extends into the beverage. The mixing device includes a condiment chamber which is defined within a mixing element for holding a condiment such as sugar. The mixing device further includes a mixing element which has a number of circumferentially-spaced slots through which the condiment is discharged into the beverage.

Method of performing a droplet-based assay. The method may include obtaining droplets encapsulated by an immiscible liquid and packed closely together in a monolayer, performing a reaction in the droplets while packed closely together in the monolayer; and collecting data related to an analyte from a plurality of the droplets while the droplets remain closely packed together in the monolayer.

The present application is directed towards systems for adding components to materials being fluidized in a vibratory mixer by use of atomizers or sprayers. A mechanical system can fluidizes, mix, coat, dry, combine, or segregate materials. The system may comprise a vibratory mixer, mixing vessel containing a first material and a sprayer to introduce a second material. The vibratory mixer may generate a fluidized bed of a first material and the sprayer, coupled to the mixing vessel, may introduce a second material onto the fluidized bed to mix the materials in a uniform and even fashion.
