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. The treatmenr fluid can comprise a water-based fracturing fluid or a waterless liquified petroleum gas (LPG) fracturing fluid.

A vane for an impeller of an agitator for mixing or agitating a process fluid includes a socket for mounting the vane to an impeller and a blade for mixing or agitating the process fluid, the blade being connected to the socket, the blade having a leading edge, a trailing edge, and a blade tip extending from the leading edge to the trailing edge at the end of the blade facing away from the socket, and the blade having a height and a width. The height is the maximum distance of the blade tip from the socket and the width is the distance of the leading edge from the trailing edge. The blade has a maximum width that is at least 55 percent.

A bioreactor system and packaging is provided. The bioreactor system includes a vessel for housing biomaterials for processing and a support structure. The vessel includes a flexible material defining a chamber and a mixing system positioned within the chamber. The mixing system includes an agitator for imparting motion and mixing to the contents of the vessel and includes a base affixed to the flexible material at a base section of the chamber, a shaft moveably mounted in the base and extending from the base into the chamber and at least one mixing element mounted to the shaft, the shaft configured to be driven by a motor magnetically coupled to the shaft and external to the lower portion of the chamber. The support structure is connected to the mixing system such that the shaft is moveable therein and configured to cooperate with an external structure to provide support for the shaft.

A mixing device and methods of utilizing the same. More specifically, embodiments of the present disclosure relate to a mixing device that may be used to make medications and specialized pharmaceuticals for administration via intrathecal infusion therapy, or the like. A mixing device may comprise an upper chamber, a lower chamber having four compartments for accepting an amount of medication, wherein the upper chamber and the lower chamber may be coupled and may be used to mix and make medication accessible via a Luer Lock adapter, termination, or the like, wherein the device is in compliance with USP 797 standards.

Embodiments of the present invention include a method and system for controlling the flow rate of materials into and out of the blender. The system includes the control and management of an on-site storage system for each component of a mixture, regulating the delivery rate of a blend mixture into a blender hopper, regulating the exit rate of the blended mixture from the blender hopper, and coordinating the flow of materials into and out of the blender.

A method includes the step of receiving a first weight value from a sensor associated with a feed mixer. A first rotation speed associated with the first weight value is monitored. A second weight value is received from the sensor associated with the feed mixer and a second rotation speed associated with the second weight value is monitored. A mixing profile is generated based on the first weight value, the second weight value, the first rotation speed, and the second rotation speed. In one embodiment, a first feed ingredient is associated with the first weight value and a second feed ingredient is associated with the second weight value.

There is provided an arrangement (100) which allows for mixing a first fluid with a second fluid at a predetermined volume mixing ratio in a capillary driven fluidic system. The arrangement (100) allows filling an initially empty mixing chamber (110) with the first fluid. The arrangement then allows emptying a predetermined fraction of the first fluid from the mixing chamber (110) such as to form an empty space in the mixing chamber (110). The arrangement then allows filling the empty space of the mixing chamber (110) with the second fluid, thereby allowing a predetermined volume of the first fluid to mix with a predetermined volume of the second fluid over time.

A stirring unit of a machine for making liquid or semi-liquid food products, including: a first base element rotatable about a first axis and having a plurality of first mixing vanes and a plurality of scraping appendages connected to the mixing vanes; a first actuator, connected to the base element to set it in rotation about the first axis, a second base element rotatable about a second axis and having a second mixing vane; a processing container forming a processing chamber for processing a base product and in which the first base element and the second base element are mounted; a second actuator, connected to the second base element to rotate it, the first base element and the second base element being configured to rotate independently of each other and the first actuator and the second actuator being configured to be activated independently of each other.

A functional water producing apparatus in an embodiment includes: a water pressure regulator configured to regulate the water pressure of the ultrapure water, the water pressure regulator having a pressure regulating valve configured to regulate a water pressure of the ultrapure water to an almost constant pressure and a feed water pump configured to pressurize the ultrapure water; a dissolving device configured to dissolve functional gas imparting a specific function in the ultrapure water regulated the water pressure by the water pressure regulator; and a control device configured to control the feed water pump to regulate the water pressure of the functional water to a predetermined constant pressure based on a water pressure or a flow rate of the functional water flowing out of the dissolving device.

Improvements in an agitator is disclosed. The agitator has a central body with sides that have blades that flex or bend inward upon insertion and then expand once the pass through the neck of the bottle. The side are elongated and allows the mixer to have an orientation within the bottle. The orientation allows for a buoyancy of the mixer to break-up powder or fruit that typically floats on the surface of the liquid. The side elements can cut into fruit and pulverize power to blend the ingredient(s). A carrier or case for the mixer provides a container for the mixer to dry and further collects and water from the mixer. A removal hook allows a user to snag one of the ends or a side element. The side flexing elements of the mixer will bend inward to pass the mixer out the neck of the bottle.
