Abstract: A mixing device for liquids is described, wherein improved control of the mix is achieved by restructuring the components so that the character of the mix can be observed easily and corrections effected simultaneously. The disperser/mixer incorporates a moveable and rotatable support structure attached to a piston-in-cylinder arrangement. Hydraulic pressure, pneumatic pressure, or a combination thereof in the cylinder is controlled from a unit on the support structure, rather than the base, through a modified piston fixed to the support structure and containing a passageway for hydraulic fluid, rather than through the cylinder.

Abstract: In a mixing process and a mixing means a relative motion of a mixing vessel with respect to a mixing tool is provided such that adhering mixing products are removed from the bottom and the walls of the mixing vessel.

Abstract: An apparatus for converting hard frozen confection to soft frozen confection, by single servings, flavoring and extruding it, is described. A super fresh product with outstanding flavor and consistency is produced. Fruit additions remain soft and flavorful, not frozen; cookie additions remain crisp, not soggy as in ordinary ice cream. Hundreds of flavor combinations become practical to make. The invention utilizes a piston and cylinder to pressurize the product for extrusion, and a special rotating wheel, on a retractable shaft thru the piston, that performs the mixing, cutting, milling, and sweeping functions. Aggregates are swept into a central extrusion orifice by this wheel. The commercial version of the apparatus requires 1/10 HP to operate, and weighs 62 pounds. The "household" version of this machine weighs 30 pounds.

Abstract: A magnetic stirrer apparatus includes a vessel for liquid and a floating stirrer. The floating stirrer is rotated by a magnet driven by a magnetic field generator laterally of the vessel, and a guide rod through the floating stirrer restricts its movement to rotary movement and substantially vertical movement with change in the liquid level. The magnetic field generator is operative at any level of the liquid in the vessel.

Abstract: A hydraulically powered mixing aerator rides on an upright beam member for submersion in a body of water such as an equalization basin, oxidation ditch or sludge holding tank used in sewage treatment plants. The aerator employs a submersible, hydraulically powered mixing motor driving a propeller which is mounted on the beam member by a slidable bracket for height adjustment. The beam member is swingably supported to allow adjustment of the vertical plane angle. Because the beam member is also mounted for rotation, substantially any attitude or position of the mixer can be selected for creating an efficient flow pattern within the body of water. The speed at which the propeller is rotated, and therefore, the rate at which the water is circulated and aerated, is selectively adjustable. The hydraulically driven motor provides for a low speed and high torque rotation of the propeller without the use of a reduction gear.

Abstract: An automatic stirring device for stirring the contents of a cooking utensil includes a plurality of support arms. The support arms have insert pads to grip the sides of a cooking utensil. An agitator with a center post and agitator blades extends downward into the cooking utensil and a motor, mounted in one of the support arms with a drive shaft driving a central gear, rotates the agitator. One of the insert pads is slidably mounted to its support arm and may be operated to exert an inward force against the side of the cooking utensil to retain the stirring device on the utensil. A support pin may be screwed into the outer end of each support arm to prevent rotation of the stirring device about the cooking utensil by contacting the handle of the utensil and also to support the stirring device in a bath of soapy water for automatic cleaning. The agitator blades are adjustable to fit various sized utensils.

Abstract: Slush freezing apparatus with an upper liquid reservoir provided with a rotary agitator above the divider plate between the upper liquid reservoir and lower freezing chamber. The agitator stirs the liquid in the reservoir, thus redissolving ice which forms in the reservoir or which migrates into the reservoir from the freezing chamber. This action keeps the reservoir free of ice. A sealing ring above the divider plate has a contractible loop which interrupts the continuity of the ring and leaves a gap therein. This gap is disposed above the inlet to the dispensing spigot from the freezing chamber, thus to channel flow of liquid from the reservoir to the freezing chamber to the vicinity of the spigot inlet and flush the inlet with liquid from the reservoir and inhibit ice formation over the inlet.
