A paddle mixer for evenly and efficiently mixing a volume of aggregate with minimal spillage is described. The paddle mixer includes a first portion, a second portion, a first paddle, and a second paddle. The paddle mixer may include a means for adjustably fixing the first portion to the second portion. The first paddle and the second paddle are arranged on the first portion and the second portion, respectively, such that the first paddle and the second paddle are perpendicular to each other, promoting mixing of the volume of aggregate with a whirlpool effect allowing mixing with minimal spillage. The first paddle and the second paddle may also be arranged perpendicular to each other by the means for adjustably fixing the first portion and the second portion.

A mixing machine includes a mixing head and at least one connection means for connecting a mixing container containing material to be mixed to said mixing head for forming a closed mixing container. The mixing head, as part of a pivotable assembly, is pivotably mounted with respect to a frame such that the closed mixing container formed from the mixing head and the mixing container can be pivoted relative to the frame for performing the mixing process. The mixing head carries at least one rotationally-driven mixing tool. The mixing head comprises a head plate having a connecting flange molded thereon which is configured as an annular disc and comprises a planar contact surface. At least two ring seals of differing diameters are arranged in said contact surface of the connecting flange at a spacing between each other, such that mixing containers with different connection diameters of their mixing head side can be connected to said mixing head. The at least one connection means is configured for gripping mixing containers which differ in the diameter of their connection sides.

Described herein is a container suitable for pneumatic metering of a component situated therein into another container, wherein the container includes a container body, a container base, and a removable cover suitable for closing the container. The container has at least one valve head, at least one compressed air connection for the pneumatic driving of the valve head and at least one further compressed air connection that are integrated into the cover of the container, and a stirrer that is also integrated into the cover. Also described herein are the use of the container, a metering system including at least one container, a method for pneumatic metering using the container, and a method for producing a coating composition or a precursor thereof that can be used in the automotive industry, which method makes use of the container.

A dosing machine for dosing fluid products includes: containers having vertical longitudinal axes and configured to contain fluid products, rotary stirring elements located inside respective containers and operable in rotation by electric motors, and a dispensing head having nozzles connected to respective containers, where each container is associated with a level measuring device having: a floater containing a permanent magnet and free to move inside the container, a magnetic detector arranged outside the container, and having magnetic sensors spaced apart from each other in a vertical direction and each of which is configured to detect a variation in a magnetic field caused by passage in its proximity of said floater, and a control unit which analyzes signals provided by the magnetic sensors to detect a fluid level inside the container and passage of the floater in a vicinity of one or more of said magnetic sensors.

A method of producing a granular aggregate in which wet granulated substances including active material particles, conductive material particles, a binding agent for binding the active material particles and the conductive material particles, and a solvent are aggregated includes adding a binding agent solution in which the binding agent is dissolved in the solvent to the active material particles having a solvent absorbing property, mixing the binding agent solution and the active material particles such that a primary granular aggregate in which granulated primary granulated substances are aggregated is produced, and mixing the conductive material particles into the primary granular aggregate and producing a granulated granular aggregate.

A system and process for removing solids from raw, untreated liquid that combines mechanical techniques, such as via shakers, hydrocyclones and/or centrifuges, with an additive technique for removal of smaller solids. The additive is selected according to the application. In drilling mud applications, preferred additive embodiments are polyaluminum chloride or polyacrylamide flocculants. Preferably, liquid additive precursors are pre-mixed separately and are then blended before injection into the solids removal process. Some embodiments provide an externally-actuated rack and pinion mud screen lock for simplified screen lockdown on shakers. Some embodiments provide a separate preliminary processing and feed system for pretreatment of the raw, untreated liquid.

A single-use bioreactor is provided.
