A microwavable container for use in a microwave oven that includes provisions to stir or mix food during microwave cooking. This mixing action is achieved by utilizing the motor of the microwave oven. Such mixing provides more even heating of food, and reduces the need to stop the microwave oven to manually stir food.

A fluid-agitating tank assembly is disclosed. The tank assembly includes a tank filled with a fluid, and an agitator disposed in the tank so as to be at least partially immersed in the fluid and supported by the tank in a rotatable manner about an axis. The agitator includes a double helix disposed in an upper volume of the tank and adapted to act on the fluid to transform unidirectional rotation of the agitator about the axis into a bidirectional movement of the fluid in the tank towards bottom and top portions of the tank, and at least one rotary blade projecting transversally from the axis, disposed in a lower volume of the tank, and rotating about the axis to move the fluid towards at least one lateral outlet of the tank.

A manual mixer serves to facilitate mixing and agitating materials for use during surgery. For example, the manual mixer includes a body portion defining an interior area, a mixing assembly provided in the interior area of the body portion, a crank assembly for actuating the mixing assembly, and a valve assembly. The mixing assembly serves to mix and agitate the materials provided in the interior through rotation of a plunger portion and a spring attached thereto, and through upwards and downwards movement of the plunger portion in the interior area. Rotation of the crank assembly serves to rotate the plunger portion and the spring attached thereto, and effectuate upwards and downwards movement of the plunger portion. The valve assembly can be opened to facilitate dispensing of the materials from the interior area.

A downhole tool includes a housing configured to be placed into a subterranean environment and a mixer disposed in the housing. The mixer includes a first inlet configured to receive a fusible metal or alloy component and a second inlet configured to receive a solid metal or semi-metal component. Additionally, the mixer includes a mixing chamber configured to mix the fusible metal or alloy component and the solid metal or semi-metal component to form a liquid or partially liquid alloy. Further, the mixer includes an outlet configured to discharge the liquid or partially liquid alloy into the subterranean environment. The liquid or partially liquid alloy is configured to harden into a solid alloy over time.

A microfluidic printing nozzle for 3D printing may include a mixing chamber, a first inlet for connecting with a first ink source, the first inlet located at a first end of the mixing chamber, and a second inlet for connecting with a second ink source, the second inlet located at the first end of the mixing chamber. An outlet may be located at a second end of the mixing chamber, and a generally cylindrical impeller may be rotatably disposed in the mixing chamber between the first end and the second end. The cylindrical impeller may include an outer surface, and the outer surface of the impeller includes a groove, a protrusion, or both, to facilitate mixing of fluidic inks flowing from the first end to the second end of the mixing chamber.

Systems and methods of producing a frozen food product include dosing ingredients with a liquefied gas while mixing the ingredients using self-cleaning interlocking beaters. The beaters are optionally also disposed to clean a container in which the ingredients are frozen. The rate and amount of cooling is controlled by measuring the quantity of liquid nitrogen, measuring viscosity of the frozen food product, measuring temperature, and/or the like.

Methods and apparatus are disclosed for mixing proppant and other solids with one or more fracturing fluids to form a fracturing slurry, and for delivering the fracturing slurry to a wellbore. In the example systems as described herein, the proppant is mixed with the fracturing fluids through an assembly that limits the number of pumps that are required to move the relatively abrasive proppant]containing fluids. Additionally, in the example systems, the proppant is mixed within enclosed structures, thereby minimizing the escape of dust and other particulates into the surrounding atmosphere and onto the equipment at the well site.

To provide a dispersing device that carries out an appropriate dispersion having a good yield, processing within an appropriate temperature range, and having a high power to disperse. The dispersing device disperses a mixture that is slurry or a liquid by causing the mixture to flow between a rotor and a stator toward the outer circumference by centrifugal force. It comprises a container, a cover assembly that closes an upper opening of the container, a stator that is fixed under the cover assembly, a rotor that is disposed to face the lower surface of the stator, a rotary shaft that rotates the rotor, a bearing that is located above the stator, and a spacer that is detachably disposed between the rotary shaft and the rotor to adjust a gap between the rotor and the stator.

The invention relates to a device (1a . . . 1g) for processing thermoplastic material, comprising a storage container (2)/a conveying line (11) for plastic particles and a conveying screw (3) connected thereto. The device (1a . . . 1g) further comprises an extruder (4) which connects to the conveying screw (3), and a tempering device (7) arranged in the course of the conveying screw (3). In addition, a temperature sensor (8, 8a, 8b) is arranged in the course of the conveying screw (3)/the extruder (4), and/or means (10) are provided for detecting a load of a drive (6) of the extruder (4). Finally, the device (1a . . . 1g) comprises means for influencing the tempering device (7) and an open loop control/closed loop control (9) which is connected to the at least one temperature sensor (8, 8a, 8b) and/or the influencing means of the tempering device (7). Furthermore, an operating method for the device (1a . . . 1g) is specified, in which the plastic particles are temperature-controlled by a tempering device (7) in the course of the conveying screw (3).

A frosty swirl machine includes a housing, a funnel, an auger for swirling ice-cream with other additives to become a mixture, and a protective cap. The protective cap has a passage opening movably mounted at a mixture outlet of the funnel, in such a manner that the protective cap is capable of moving between a opened position and a closed position, wherein in the opened position, the protective cap is moved to align the passage opening with the mixture outlet of the funnel so as to allow the mixture to pour out of the funnel through the mixture outlet and the passage opening, wherein in the closed position, the protective cap is moved to block the mixture outlet so as to prevent the mixture from being poured out of the funnel.
