The present disclosure relates to a mixing assembly for a fluid mixing system. The mixing assembly includes a first rotational assembly having a first casing and a first hub rotatably mounted to the first casing, a second rotational assembly having a second casing and a second hub rotatably mounted to the second casing, an elongated member having a first end coupled with the first hub and an opposing second end coupled with the second hub, and one or more impellers secured to the elongated member.

A liquid mixing system includes a support housing at least partially bounding a compartment. A mount is secured to the support housing. A drive motor assembly is configured to engage a drive shaft for moving the drive shaft within the compartment of the support housing. A four bar linkage system extends between the mount and the drive motor assembly, the four bar linkage system being movable between a first position wherein the drive motor assembly is disposed at a first elevation and a second position wherein the drive motor assembly is disposed at a second elevation that is different from the first elevation.

A mixing machine 1 comprising a mixing head 3 having element(s) for connecting to a receptacle to form a mixing container. The mixing head 3 is pivotably supported in a frame 2 such that the mixing container can pivot for the mixing process. The mixing head 3 has at least one rotationally driven mixing tool whose drive shaft 23 extends through the wall of the mixing head 3. The mixing head 3 has a double wall with a perforated inner wall 8. The perforations form a fluid path from the chamber surrounded by the inner wall 8 to the intermediate wall chamber 10. The intermediate wall chamber 10 is connected to a pressure adjustment device for adjusting the pressure. A flexible liner 15 is arranged in the mixing head 3 on its inner surface, which liner 15 can be fixed to the inner wall 8 of the mixing head by applying a vacuum.

A stirring staff arrangement (29) for being connected to a stirring machine that can be combined with a container (20) for receiving liquids, wherein the container, in an upper bottom wall (26), has a filling opening being closable with the help of a lid (28) for filling the container, wherein the stirring staff arrangement has a bar-shaped stirrer element carrier (30) embodied as a hollow shaft for receiving a stirring machine shaft, and stirrer elements (32) coupled to the stirrer element carrier so as to be pivotable, in such a manner that the stirrer elements have been pivoted, in a mounting configuration, with a free stirrer element end, against an axis of rotation of the stirrer element carrier, wherein a spring means is arranged between the stirrer elements and the stirrer element carrier, in such a manner that the stirrer elements, in an operating configuration, are charged with centrifugal force as a consequence of a rotation of the stirrer element carrier and take a pivoted position that depends on the rotational speed of the stirrer element carrier, a stirring angle being realized with respect to the axis of rotation, wherein the free stirrer element ends are arranged at a stirring distance r from the axis of rotation and the spring force, which increases as the stirring angle grows, opposes the centrifugal force.

This disclosure relates to equipment utilized to manufacture chemical agents, particularly biopharmaceuticals. In some embodiments, reactor systems comprising a mobile carriage assembly; a disposable reaction container removably attached to the carriage assembly; and, a carriage holder into which the mobile carriage assembly may be removably inserted are provided.

An apparatus for disintegration (or mixing) of a solid in a vessel containing liquid, has a control unit and an ultrasound transducer for generating ultrasonic energy under control of the control unit. A coupling medium in communication with the ultrasound transducer is adapted to receive the vessel. Ultrasonic energy is transferred to the contents of the vessel such that in use the ultrasonic energy causes disintegration of the solid into the liquid contained in the vessel. An agitating mechanism is adapted to agitate the disintegrated solid in the liquid contained in the vessel. The agitating mechanism may include a paddle having a coating of flavouring material. A method for disintegration of a solid in a vessel is also disclosed.

A universal driven shaft retaining system includes a collet chuck holder that circumferentially engages a collet chuck with substantially inward compression during inward co-linear movement of a drawing bar creating a clamping (locking) effect on an inserted driven shaft.

A chopping system generally includes a container having a bottom wall and a sidewall together defining a cavity. The sidewall has a rim, and the bottom wall has an upper surface with a central area having an entirely smooth contour. The system also includes a drive assembly configured for mounting on the rim to cover the cavity, and the system further includes a working assembly comprising at least one working member configured for operative attachment to the drive assembly such that, when the drive assembly is mounted on the rim, the working member is disposed within the cavity. The system further includes a base attached to the working assembly such that the working member is rotatable relative to the base. The base has a bottom surface that substantially mirrors the contour of the upper surface within the central area so as to be seated substantially flush thereagainst.

Systems and methods for preparing construction material mixtures. A container can include a flexible body having an interior for receiving and holding construction material mixture components to be mixed. The construction material mixture components can be mixed in the interior by rotating a mixing tool. The flexible body is collapsible for forcing the construction material mixture out of a mouth of the container. The flexible body can be everted to facilitate cleaning the interior of the flexible body. The system can also include a stand, a mixing tool, a funnel, and/or a measuring cup.

Methods and apparatus for the treatment of animal waste are disclosed, together with a treated animal waste and fertilizer and growth media products derived therefrom.
