A module includes a housing, a sealing feature, a locking feature, and an agitator. The housing has an opening separating inner and outer surfaces and a boss that extends through the housing such that part of the outer surface forms an inner bore of the boss having a terminus pointing toward the opening. The agitator has a base, a shaft, and a mixing element coupled to the base such that the base, in cooperation with the sealing feature, circumferentially seals the opening of the housing to form a cavity defined by the inner surface. The shaft passes through the inner bore. The locking feature when engaged permits independent or simultaneous translational and rotational movement of the shaft while an area between the terminus of the boss and the shaft remains mechanically sealed during the movement against liquid or powder encroachment into a clean area of the inner bore.

Systems and methods for using one or more pre-filled, portable containers, instead of pneumatic transfer, to move bulk material from a transportation unit to a blender receptacle of a blender are provided. A transportation unit may deliver one or more containers of bulk material to the well site, where the containers may be disposed in an elevated position around the blender receptacle. A gravity feed outlet may extend from one or more containers to route bulk material from the one or more containers directly into the blender receptacle. Since the transportation unit is able to unload the portable containers of bulk material without pneumatic transfer, the stackable containers may enable a cleaner and more efficient bulk material transfer at the site.

The present invention relates to a method of dispersing fine particles in an aqueous or polar solvent. The dispersant comprises a compound of general formula (I): In general formula (I), AO is an alkylene oxide group selected from ethylene oxide and propylene oxide, R.sup.1 is selected from a methyl group, an ethyl group, a propyl group, a butyl group, and a pentyl group, R.sup.2 is a carboxylic acid terminated group comprising 1 to 5 carbon atoms between the carboxylic acid and the polyalkylene glycol group (-(AO).sub.n—O—), and n is 2 to 100. A dispersion of nanoparticles comprising the dispersant, use of the dispersant, and a method for dispersing nanoparticles is also disclosed.

Provided is an ultra-dispersion mixer, for stirring a mixed material for producing a high-quality slurry for an electrode of a secondary battery within a short time by disposing a low-speed blade and a high-speed blade for stirring a mixed material in a chamber so as to easily and effectively disperse elements of the slurry of a secondary battery, supplied to a mixer during a procedure of preparing the slurry of a secondary battery produced by performing mixing procedures multiple times, and disposing blade parts having a plurality of stirring characteristics so as to realize various stirring characteristics in the mixed material on the high-speed blade to increase the dispersion of the mixed material while the mixed material circulates in a high-shear disperser of the chamber and to simultaneously increase the temperature of a supplied solution at the beginning of stirring of the mixed material in the chamber.

The systems and methods described herein assist a user in executing a recipe by recording and associating a blend sequence of blend steps with the recipe upon a first execution of the recipe. The systems and methods described herein further assist the user in modifying and executing the recorded blend sequence upon a second and subsequent execution of the recipe.

A mixing and dispensing container for mixing and dispensing dental materials. The mixing and dispensing container includes: a plunger; an open-ended liquid receptacle adapted to receive the plunger; and a main body with a proximal end, a distal end, a chamber open at the proximal end and an aperture in the distal end. The chamber is adapted to receive the liquid receptacle. The dental capsule mixes various components of the dental materials and forms a dental paste for dispensing. The container is especially envisaged for use in mixing of components to provide a paste for dental use.

A method of hydrating a dry powdered viscosifier such as a powdered polymer is disclosed. The method includes mixing the powdered viscosifier with a solvent such as water to form a mixture; moving the mixture through a cavitation zone; inducing energetic shock waves and pressure fluctuations in the mixture by mechanically inducing cavitation events within the mixture, the shock waves and pressure fluctuations untangling, separating, and straightening polymer molecule chains and distributing the chains throughout the mixture, and extracting the resulting hydrated viscosifier from the cavitation zone.

One aspect relates to a device for mixing a polymethyl methacrylate bone cement formed of two starting components and for storing the starting components of the bone cement. The device has a tubular cartridge with a cylindrical interior. A powder is contained in a front of the cartridge and a container containing a monomer liquid is arranged in a rear of the cartridge. A discharge piston is arranged between the container and the powder, and a conveying piston is on the side of the container opposite the discharge piston. The discharge piston and the conveying piston are arranged in the interior of the cartridge movably in the longitudinal direction. A conduit is provided that connects the front part and the rear part of the interior of the cartridge to one another in a manner permeable for the monomer liquid and for gases and which is impermeable for the powder.

A mixing paddle that is configured to rotate about a horizontal rotation axis and includes at least one eccentric arm which includes a first portion inclined with respect to a plane containing the rotation axis, so as to cause the ingredients contained in the mixing chamber to move in a first axial direction when the mixing paddle rotates in a first direction of rotation, a second portion having a cross section oriented radially with respect to the rotation axis in order, when the mixing paddle rotates in a second direction of rotation, to bring about a radial movement of the ingredients towards the outside of the mixing chamber.

The invention relates to a system for producing and/or preparing confectionery compounds from at least one liquid raw material and granular and/or powder raw materials. The system includes at least one first mixing container and at least one other product-processing device. The first mixing container has at least one raw material inlet, a product outlet, and a mixing device for mixing the raw materials in an at least largely homogenous manner. According to the invention, at least the mixing container includes at least one spray device in an upper container region for introducing the at least one liquid raw material, wherein at least one exit cone of the spray device is oriented in the direction of an inner wall surface of the first mixing container at least in some regions. The invention further relates to a method for cleaning a system for producing and/or preparing confectionery compounds.
