A combination unit for vacuuming, cleaning and conditioning fluids. The unit may comprise a vacuum pump circuit and tank, a mixing tank and a centrifuge system. The invention also includes a combination tank comprising a vacuum tank partially incorporated into a mixing tank. A mixing tank may comprise a system of mixing conduits and mixing apparatuses to shear drilling fluids and additives, the mixing tank including a rounded base and a drain to cycle the fluid back through to the mixing tank.

A fluid container and dispenser have an associated source of power to energize a light source coupled in optical communication with portion of the container to energize the luminescent fluid contents before they are dispensed.

A single-pass flow-through dry chemical mixing trailer for use with a well has a trailer, a refillable liquid storage tank, a main liquid storage tank valve, a liquid storage tank inlet valve, an onboard power supply, a motor with a fuel supply, a transmission, a fluid circulation loop, a self-priming bidirectional flow alternating centrifuge pump, an automated mixer assembly, and a discharge tank. The refillable liquid storage tank prevents backflow to the self-priming bidirectional flow alternating centrifuge pump while flowing the homogenized slurry to the well and the dry chemicals introduced at the automated mixer are subjected to high shear forces, incorporating the dry chemicals into the liquid with increased dispersion and reduced agglomeration.

In accordance with presently disclosed embodiments, systems and methods for managing bulk material efficiently at a well site are provided. The disclosure is directed to a container support frame that is integrated into a blender unit. The support frame is used to receive one or more portable containers of bulk material, and the blender unit may include a gravity feed outlet for outputting bulk material from the containers directly into a mixer of the blender unit. The blender unit with integrated support frame may eliminate the need for any subsequent mechanical conveyance of the bulk material (e.g., via a separate mechanical conveying system or on-blender sand screws) from the containers to the mixer. As such, the integrated blender unit may be lighter weight, take up less space, and have a lower cost and complexity than existing blenders.

An object of the present invention is to provide a novel solid phase peptide synthesis method for synthesizing a large amount of a peptide. Another object of the present invention is to provide a novel solid phase peptide synthesis method for synthesizing a high-purity long-chain peptide. Still another object of the present invention is to provide a novel solid phase peptide synthesis method causing fewer side reactions. The present invention relates to a method for producing a peptide, and the method comprises solid-phase synthesis of a peptide under stirring with a centrifugal stirrer having no impeller.

Provided are a system for manufacturing dispersion liquid of carbon nanotubes and a method of manufacturing a dispersion liquid of carbon nanotubes using the same. The system includes; a mixing device supplied with solvent and carbon nanotubes, and storing a admixture of the solvent and the carbon nanotubes; a first dispersion device connected to the mixing device, performing a primary dispersion of the carbon nanotubes by an operation of a rotor and a stator, and then performing a secondary dispersion to form bent portions in the carbon nanotubes while discharging the carbon nanotubes through penetration holes of the stator; and a second dispersion device performing a tertiary dispersion of the carbon nanotubes to selectively cut the bent portions of the carbon nanotubes by irradiating a laser when the secondarily dispersed admixture recirculates to the mixing device.

Provided are blender systems and methods that selectively control fan operation within the blender systems. For example, a blender system includes at least a fan, a blade assembly, and a motor used to operatively drive the blade assembly for blending. Operation of the fan may be independent of the operation of the motor. One or more operating parameters of the fan may be adjusted to selectively control the operation of the fan when one or more conditions are met. Adjusting the one or more operating parameters of the fan may include increasing or decreasing a speed of the fan. Further, adjusting the one or more operating parameters of the fan may include powering on or powering off the fan.
