The driving device (12) comprises a drive shaft (16) and an electric drive motor (20) wherein the drive motor (20) is accommodated sealed in the housing (11). The drive motor (20) comprises an outer, hollow stator (21) and a rotary rotor (22) which is centrally accommodated therein and is configured at least partially hollow. The rotor (22) is rotatably supported at the housing (11) and comprises a coupling device (23) for non-rotatable coupling with the drive shaft (16) to drive the at least one agitator blade (13-15) by means of the drive shaft (16).

A system for applying a building material, including: a movement device for modifying a site of application in a space; a first component of the building material; a second component of the building material; and a mixer for mixing the first component and the second component, the mixer including a drive and a mixing chamber provided with a stirrer shaft and a conveyor device, the conveyor device being designed as a screw conveyor with windings, and the mixer being adapted to the building material.

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.

An agitator rotor includes a shaft, rails, and a rod. The shaft defines a longitudinal axis. The rails extend radially from and are coupled to the shaft. The rails are separated from each other along a length of the shaft. Each rail includes a surface defining a non-zero angle with respect to the longitudinal axis of the shaft. The rod includes a first end coupled to a first one of the rails. The rod includes a second end coupled to a second one of the rails. A projection of the first end and the second end of the rod in a plane perpendicular to the longitudinal axis of the shaft defines a minor arc about a portion of the shaft.

A mixer for generating a flow of liquid includes a stationary body, an axially extending drive shaft protruding from the stationary body, a propeller, and a clamping sleeve assembly configured to interconnect the drive shaft and the propeller with each other in order to transmit a rotational motion. The clamping sleeve assembly has an axial clamping length and includes an inner clamping sleeve and an outer clamping sleeve. The inner clamping sleeve has the shape of a tubular wall having an inner surface abutting the drive shaft and an outer surface abutting the outer clamping sleeve and wherein the outer clamping sleeve has the shape of a tubular wall having an inner surface abutting the inner clamping sleeve and an outer surface abutting the propeller. Both the inner surface of the outer clamping sleeve and the outer surface of the inner clamping sleeve are cylindrical along the axial clamping length.

The invention of the present disclosure is that of functional packaging systems useful for reducing the separation of solid and liquid constituents of its contents. The invention is particularly useful for preventing the undesirable separation of solid and oil phases of food products such as natural peanut butter that is manufactured without the use of undesirable additives such as hydrogenated vegetable oils, lecithin, monoglycerides, diglycerides and other substances that slow separation of the solid and oil phases from one another. In one embodiment, the invention comprises a container with a rotating base which when rotated actuates the agitation of the product contained within, as a result of the concurrent rotation of one or more axes configured with an agitator or equivalent means of stirring or mixing the contents. The invention is further provided with hermetic sealing means and the like to ensure food safety.

An automatic stirring cup, comprising a cup body, a stirring ball arranged at the bottom of a cavity of the cup body and a power base for supplying power to the stirring ball; a first electrode for electrically connecting the stirring ball and the power base is arranged at the bottom of the cup body; a first magnet is arranged in the stirring ball, and a second magnet matched with the first magnet is arranged at the bottom of the cup body, and the stirring ball and the cup body are magnetically connected; a third magnet matched with the second magnet is arranged at the power base, and the cup body and the power base are magnetically connected. The automatic stirring cup could avoid the water leakage problem during the use of the automatic stirring cup in the prior art.

A gas dispersion system may include a drive mechanism, a drive shaft having a proximal end operably coupled to the drive mechanism, extending to a distal end, and configured to transfer rotational motion and torque, a mixing element arranged at or near the distal end of the drive shaft including a hub and multiple blade pairs, each blade pair including an upper blade and a lower blade secured to the hub and cantilevering freely and generally radially away from the hub.

A mixer is provided having two tines. These tines have a bulbous configuration and can be traversed between an outward biased position and a compressed inward position. The tines are bendable. When distal ends of the tines are pushed against an inner surface of the container, the tines criss cross so that the distal end portions of the tines rub or scrape the bottom surface of the container.
