A fluid mixing system includes a flexible bag having a first end, an opposing second end, and an interior surface bounding a compartment; a retainer coupled to the second end of the flexible bag, the retainer having a retention cavity formed thereon that communicates with the compartment of the flexible bag; and an elongated member having a first end rotatably coupled to the first end of the flexible bag and an opposing second end freely disposed within the retention cavity of the retainer so that the second end of the elongated member can rotate within the retention cavity relative to the retainer.

An assembly for supporting a member in a vessel comprises a clip comprising an arm with a first end attached to a panel and a second end opposed to the panel. The panel is secured in the vessel. The assembly also comprises a plate slidably disposed between the second end of the arm and the panel. The subject matter also pertains to the clip itself and the method of use.

A fluid mixing system includes a flexible bag having a first end, an opposing second end, and an interior surface bounding a compartment. A first rotational assembly includes a first casing mounted to the first end of the flexible bag and a first hub rotatably mounted to the first casing. A second rotational assembly includes a second casing mounted to the second end of the flexible bag and a second hub rotatably mounted to the second casing. An elongated member has a first end coupled with the first hub and an opposing second end coupled with the second hub, the connector being flexible and having a uniform flexibility along its entire length. A first impeller is mounted to the connector.

An efficient automatic liquid-liquid extracting machine includes a body. At least one set of stirring extractor is arranged on the body, the stirring extractor includes a cylindrical separating funnel and a stirring motor that are fixed on the body, a bottom funnel opening of the cylindrical separating funnel is connected to a three-way liquid separating device, the stirring motor is arranged opposite to the opening of the cylindrical separating funnel, a motor shaft of the stirring motor is connected to a stirring device, and a stirring end of the stirring device penetrates into the cylindrical separating funnel. Since multiple mechanical stirring devices are used in the analysis of semi-volatile organics, the extraction process for multiple samples can be performed synchronously at the same time, and the solvent and the solute are brought into full contact due to the rotary mechanical stirring up and down.

A mixing vessel for accommodating components to be mixed has a container with at least one mounting depression in a side wall of the container. The mounting depression is adapted so that a mixing impeller housing of a mixing impeller is at least partly insertable, in which at least one magnet is housed for being magnetically connectable to a drive device to be driven. A locking assembly is attachable to the mounting depression from outside for locking the mixing impeller in a storage position, in which the mixing impeller is not rotatable. The locking assembly has a magnetically active element that is adapted to interact with the magnet of the mixing impeller.

The disclosure relates to a preferably automated change system for changing a mixer, comprising a mixing device, having a mixer, for mixing at least two different components for a multi-component application agent for application onto a workpiece, and a handling device for moving the mixing device, wherein the change system comprises a change station for depositing a mixing device with a mixer to be changed and preferably for receiving a mixing device with a new mixer. The disclosure relates also to a corresponding changing method.

An apparatus is described for reducing formation of ice in an ice fishing hole. The apparatus includes low voltage variable speed motor contained within a housing that draws water into and up through the housing and out of the housing through a matrix of multiple rows and columns of holes that form the water outlet.

A two component adhesive system pumps a first adhesive component and a second adhesive component into a replaceable mixing unit that can be periodically replaced when the adhesive has cured in the mixing unit. The adhesive system has a robotic arm coupled to a gripper unit which has an open position and a closed position. In the open position, the gripper unit releases the mixing unit allowing the mixing unit to be replaced. The robotic arm moves the gripper unit to install a replacement mixing unit. The gripper unit can be moved to the closed position and the adhesive can be pumped through the mixing unit.
