A mixing device suitable to mix substances or liquid or semi-liquid compounds to increase the volume thereof, including a hub which develops along a central axis and three mixing spokes connected to the hub, wherein each of the spokes comprises an external lateral fin and two upper and lower connection segments, which connect respective upper and lower ends of the lateral fin to the hub.

A hand-crank operated food processor includes a container with a removeable lid. The lid incorporates a number of gears that are operable by the hand crank to cause a drive shaft to spin, imparting a rotational force to a food processing implement such as a blade or a paddle carried on the drive shaft. The crank can be inserted into any one of a plurality of attachment points such that rotation of the crank handle in a selected attachment point will rotate the gears, and therefore the drive shaft, at a different rotational speed as compared to the rotational speed achieved at a different one of the plurality of attachment points at the same input speed from the crank.

A manual food processor includes a container with a removeable lid. The container includes a plurality of container undulations spaced along an upper portion of the container to form a seat. The lid is removably attachable to the container to enclose the interior space, and includes a food processing tool carried on a drive shaft. The lid further has a plurality of lid undulations which are complementary to and engageable with the plurality of container undulations, preventing the lid from rotating with respect to the container, and allowing removal of the lid without rotation of the lid.

A stand mixer is provided, which includes a mixing bowl and one or more beaters configured to rotate within the bowl and orbit about a common axis that is concentric with the bowl. The mixer further includes a scraper with an edge that is shaped to conform to an inside wall of the bowl, and which is also configured to orbit, with the beaters, about the common axis, while rotating at the same rate so that the edge of the scraper remains in contact with the inner wall of the bowl.

A cement mixing tool with a gearbox transmission assembly, an electric drill tool, a pair of mixing blades, a drive shaft housing assembly, a handle assembly and a splash guard. The electric drill tool is attached to the drive shaft housing assembly. The gearbox transmission assembly is attached to the drive shaft housing assembly. The pair of mixing blades are attached to opposing shafts extending from the gearbox transmission assembly. The splash guard attached to the exterior the drive shaft housing assembly. The handle assembly is attached to the drive shaft housing assembly. The resulting tool can be used by a person to mix wet cement within a wheelbarrow or other similar open topped container.

The sealing performance of a stirring device and the abrasion resistance of a seal are improved. A stirring device includes a stirring tank that defines a stirring chamber; a plurality of stirring blades that are disposed in the stirring chamber; a shear blade drive shaft that extends from a lower side of the stirring tank to the stirring chamber and rotationally drives at least one shear blade among the plurality of stirring blades; and a fixed ring and a rotating ring that is disposed radially outside the shear blade drive shaft and seals between the stirring tank and the shear blade drive shaft. A sealing surface of the mechanical seal structure is formed at the same height as or above a lowermost portion of the stirring chamber.

An elongated hollow tubular member for drinking the beverage, an agitator for mixing the beverage, and a linear to rotary mechanism combining the elongated hollow tubular member and the agitator for converting linear motion of the elongated hollow tubular member to rotary motion of the agitator for mixing the beverage.

A mixing device suitable to mix substances or liquid or semi-liquid mixtures to increase the volume thereof, includes a hub which develops along a central axis and two mixing spokes connected to the hub, wherein each of the spokes includes an external lateral fin and two upper and lower connection segments, which connect respective upper and lower ends of the lateral fin to the hub.

The present invention involves the use of a small profile device for preparation and/or delivery of cold slurry into the human body. The cold slurry can be generated within the device itself or within a separate small chamber, both of which produce a cold slurry using a cooling source and an injectable fluid. The delivery device provides continued agitation to the fluid/slurry through rotation and/or vibration of blades within the device. The fluid/cold slurry is cooled/kept cool through the use of an external cooling device, such as a cooling sleeve, that at least partially surrounds the delivery device. The cooling sleeve can cool or maintain the temperature of the cold slurry through a number of mechanisms. The cold slurry can be delivered using a device in accordance with the present invention to any tissue inside the body, including subcutaneous fat, visceral fat, and brown fat.

A dosing unit, for the controlled delivery of a solid material, including a silo, for containing the material to be delivered, having on the bottom a discharge mouth, said discharge mouth being circular, at least one extraction auger arranged inside said silo and operable in rotation around a vertical axis, at least one scraper member, located inside said silo and associated with said discharge mouth operable in rotation around said vertical axis, first actuation means of the extraction auger and second actuation means of the scraper member, at least one shutter component positioned below the discharge mouth, and moving means operatively connected to the shutter component to move it with respect to the discharge mouth.
