An implement attachment holder for a hand mixer includes a body defining opposed first and second surfaces and first and second mounting projections coupled with the body and extending away from the first surface of the body at respective first and second locations spaced apart at a first distance along a first direction. The attachment holder further includes a device retention projection extending away from the second surface of the body and partially along the first surface to at least partially overlie the first and second locations from which the first and second mounting projections extend. The device retention projection further defines at least three attachment channels extending in a second direction normal to the first direction at spaced-apart locations along the device retention projection.

A fluid holding structure fluid circulating system includes a fluid movement assembly with a propeller including a housing having a perimeter wall and a plurality of blades attached to an outer surface of the perimeter wall. A motor is mechanically coupled to the propeller and is positioned above the propeller. A buoy has buoyancy in fluid great enough to raise the fluid movement assembly adjacent to a surface of a fluid holding structure when the motor is turned off. The motor is mounted within the buoy and the propeller urges fluid upwardly toward the buoy when the motor is turned on to rotate the propeller. The propeller is completely exposed around its lateral periphery. A positioning cable is attached to the fluid movement assembly to facilitate movement thereof within the fluid holding structure.

A device aerates a drinkable liquid inside a handheld container. An aerator is detachably mounted on the container in a mounted position. The aerator has an aerator portion that extends into the liquid and that is held adjacent an interior surface of a side wall of the container in the mounted position. The aerator portion has a multitude of turbulence-inducing agitating elements, such as pores, through which the liquid in the container flows to, and impacts against, the interior surface of the side wall of the container, and mixes with ambient air in the container, when the container is manually swirled to aerate the liquid.

A bioreactor apparatus includes a vessel establishing an interior space environmentally separable from an exterior space outside of the vessel, an agitation system including mixing means arranged in the interior space and drive means adapted to rotate the mixing means. The drive means includes a drive motor that is arranged in the interior space.

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.

A system for mixing content of a container comprises a container includes an interior mixing element, an exterior drive system and a mixing device comprising an exterior bearing for coupling the exterior drive system to the interior mixing element of the container. The exterior bearing provides a driven non-rotating, nutating motion that drives the interior mixing element of the container so that it performs a mixing motion inside the container.

A stirring system for a bucket having a sidewall configured to form an inner cavity for containing liquid therein. The system a lid having a center hole extending through the thickness of the lid; a shaft extending from a first end to a second end, the shaft is configured to extend through the center hold of the lid and into the inner cavity; a quick-release device secured to the first end of the shaft; an upper perforated stirring paddle rigidly attached to and extending from the shaft; a middle perforated stirring paddle rigidly attached to and extending form the shaft, the middle perforated stirring paddle is configured to extend in a first plane parallel to the upper perforated stirring paddle; and a lower perforated stirring paddle secured to the second end of the shaft and extending along a second plane, the lower perforated stirring paddle having a first length equal to a second length of the upper perforated stirring paddle plus a third length of the middle perforated stirring paddle.

An agitator assembly includes an agitator body, a shaft and a blocking part. The shaft is assembled to the agitator body and extends through a lead-through in the agitator body into the vessel, when assembled for use, and includes a sealing to seal the rotatable shaft. The blocking part arranged at the agitator body and including a shaft opening through which the shaft is arranged to extend, a mating surface to mate with the shaft which, when brought together by axial movement of the blocking part, provides a seal between the blocking part and the shaft, and the mating surface arranged at an axial distance from the sealing in the lead-through, and when brought together by the axial movement of the blocking part, provides a seal between the blocking part and the agitator body, and that the blocking part provides a closed space around the lead-through in the agitator body.

A system for distributing ozonated fluid includes a manifold that contains a plurality of fluid paths and has one or more ozone intake ports. The ozone intake ports are fluidically coupled to one or more ozone output ports of one or more ozone supply units. The manifold includes a plurality of flow switches configured to transmit control signals to one or more controllers of each ozone supply unit in response to sensing a flow of water through the fluid paths in order to cause the ozone supply units to generate ozone. The manifold also includes a plurality of fluid mixers that are fluidically coupled to the ozone intake ports and configured to introduce the ozone generated by the ozone supply units into the water flowing through the fluid paths.

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 may have a robotic arm coupled to a gripper unit which has an open configuration and a closed configuration. In the open configuration, the gripper unit releases the mixing unit allowing the mixing unit to be replaced. The robotic arm may moves the gripper unit to install a replacement mixing unit. The gripper unit can be moved to the closed configuration and the adhesive can be pumped through the mixing unit.
