A process of the type for producing chlorinated propanes by reacting carbon tetrachloride with ethylene within a tank reactor that includes a liquid reaction mixture and a headspace above the reaction mixture wherein ethylene gas diffuses from the liquid reaction mixture into the headspace while agitating the reaction mixture, the improvement comprising transferring ethylene within the headspace back into the reaction mixture through a conduit within the mixing device that agitates the reaction mixture.

Method and apparatus for continuous processing to perform chemical or physical reactions comprises a tube in which internal axial stirrer blades mounted at the periphery of the tube are driven by a drive system. This generates tangential flow of material at the perimeter. Stationary axial baffles mounted inside the swept path of the stirrer blades convert tangential flow into turbulence and radial mixing.

A system and method for introducing a slurry mixture for making gypsum board is disclosed. The system includes, for example, a mixer, a foam injector, and a canister for mixing and moving a slurry mixture of foam and gypsum slurry. Also included in the system is an apparatus having a funnel body constructed and arranged to further mix the slurry mixture. The funnel body includes a number of baffles projecting from its inner wall towards a center and that are spaced around the inner wall. The baffles induce turbulence into the slurry mixture as the slurry mixture moves towards its outlet, thus further mixing the mixture and reducing the flow rate of the slurry mixture before its exits from the outlet for depositing onto paper to form the gypsum board.

A container, such as a disposable or single use bioreactor, optionally having one or more inlets and one or more outlets and a mixer associated with the container to cause mixing, dispersing, homogenizing and/or circulation of one or more ingredients contained or added to the container. The container includes a flexible baffle shaped and positioned within the container to improve mixing, particularly to improve low shear mixing. The baffle is positioned within the container so as to disrupt the vortex formed by the mixer, or prevent formation of a vortex. The baffle is shaped with both horizontal and vertical elements to enhance disruption of the vortex across the entire vessel height and provide homogeneous mixing throughout all operating volumes. In certain embodiments, the baffle is X-shaped.

A carbonated beverage apparatus includes a freezing cylinder for receiving a mixture, a beater device disposed inside the freezing cylinder for pushing the mixture in a spiral manner from an inlet of the freezing cylinder to an outlet thereof, and a baffle supporting arrangement positioned surrounded by the beater device, wherein the beater device is rotatable to remove the mixture from an inner wall of the freezing cylinder radially back into the freezing cylinder and to stir the mixture via the baffle supporting arrangement before flowing out of the outlet.

A food mixer is presented having mixing tool detection capability. The food mixer has a base unit with a tool attachment portion, a mixing bowl attached to the base unit, and a motor attached to the base unit. The motor has operational settings and is configured to apply a torque to the tool attachment portion. A mixing tool is removably attached to the tool attachment portion, and a controller unit of the mixer is configured to detect the mixing tool attached to the tool attachment portion and to automatically control the operational settings of the drive motor based on the mixing tool detected. A magnet carrier may be used to detect a magnetic portion of the mixing tool as it moves with respect to a magnetically-sensitive sensor in the base unit.

Disclosed are systems and methods for mixing a plurality of materials for fused deposition modeling printing. The systems and methods can both mix and extrude FDM printer filaments. The mixing can be accomplished via a mixing element rotating in a heated chamber of the extruder's hot-end in order to achieve the shear forces to induce mixing of the molten plastics. Further, the mixing element can provide a secondary driving mechanism to assist with extruding the extrudate.

An apparatus to prevent formation of a vortex has a ring-shaped gasket having a bottom surface and a top surface; and a blade assembly mounted on the top surface and comprising a center portion and plural blades of a defined height. Each of the blades extend from the center portion to the top surface, with each pair of the plural blades defining a filter based at least in part on spacing between the pair of plural blades.

In a method of producing nanoconcrete according the bottom-up approach of nano technology with the High-Energy Mixing of composition including cement, water, sand, additives and superplasticizers, the mixing is performed with flow of mixture characterized by Reynolds number and Power number in the range of 20-800 and 0.1-4.0 respectively with installation a disk horizontally into mixing assembly on the top layer of activated mixture coaxially with vertical axis of assembly and with the axis of impeller rotation on the adjustable level to avoid destroying created gel as a result of interruptions of process, to increase laminarity of the mixture flow, energy absorption by the mixture, and shear stress for creation additional quantity of the nanostructured Calcium Silicate Hydrate (CSH) gel necessary for making nanoconcrete.
