  • Patent number: 10610843
    Abstract: This disclosure relates to a magnetic mixing apparatus that mixes a sample contained in a mixing chamber using a stir bar, while minimizing the amount of contact between the stir bar and walls of the mixing chamber. In one aspect, the apparatus comprises a ferromagnetic stir bar contained in the mixing chamber, and a driving magnet and a driven magnet located on opposite sides of the mixing chamber. The driving magnet, the driven magnet, and the ferromagnetic stir bar are each capable of rotating about a respective axis. The driving magnet, the driven magnet, and the ferromagnetic stir bar are magnetically coupled such that rotation of the driving magnet induces rotation of the driven magnet and rotation of the driving magnet and the driven magnet induce rotation of the ferromagnetic stir bar. In some embodiments, rotation of the ferromagnetic stir bar within the mixing chamber mixes the sample contained within the mixing chamber.

  • Patent number: 10517438
    Abstract: An electric heating and stirring machine that heats and stirs a substance or substances placed in a carafe for brewing coffee, tea, or extracting substances into fats or oils. The device uses a motor to rotate a magnet holder upon which magnets are mounted. The rotation of the magnets magnetically rotates a stirrer, through attraction to the rotating magnets, rotation of the stirrer stirs the contents of the carafe. The contents of the carafe are heated, preferably by an infrared or induction heater located below the carafe. The base of the stirrer is heated via induction or direct infrared heat. The temperature of the substance in the carafe is measured by a thermometer. A control circuit can be used to control the speed of mixing, the temperature, and the time of both stirring and heating.

  • Patent number: 10368680
    Abstract: A cookware and geometrically patterned magnetic stirrer assembly provides cookware for heating and stirring food. A heating element heats a cooking surface on the cookware. At least one geometrically patterned electromagnetic coil is integrated into the cookware. The electromagnetic coil generates a magnetic field when an electrical current passes through. At least one magnetic stirrer operates on the cooking surface to stir the food in response to the magnetic field, in accordance to the path of geometric pattern. Controllably applying varying electrical currents through the electromagnetic coil moves the magnetic stirrer in the path of the geometric pattern at varying speeds and directions. The electromagnetic coil can be arranged in a snowflake pattern, a spider web pattern, or a helix. A controller regulates electrical current through the heating element and the electromagnetic coil to allow the heating and stirring functions to operate independently of each other.

  • Publication number: 20120294111
    Abstract: The present disclosure relates to an motor that may be used to stir or agitate a material without the drive components of the motor making direct contact with said material. Particularly, the present disclosure relates to an motor and a method of using such to stir or agitate a food material while insulating the drive components of the motor, and preventing them from coming into direct contact with the food material. The present disclosure has particular application to agitation of materials which should not come into direct contact with the drive components for safety or cleanliness purposes, such as ice cream or slushies, as well as materials with which contact is generally discouraged, such as biomedically pure substances or harsh chemicals.

  • Patent number: 8312871
    Abstract: An electronically controlled, brushless DC, electromagnetic induction drive apparatus for use in a paintball marker active loader capable of directly driving the feeder element in the active loader while providing user selectable torque transfer capability and rotational speed whether used to continuously or intermittently rotate the loader feeder element. A plurality of selectively polarity reversible electromagnets are disposed in the loader housing and act to move a plurality of magnetic drive elements disposed on the rotating feed cone to rotate the feed cone and cause paintballs to be fed into the paintball marker via a feed tube. A controller linked to the marker firing sequence manages the sequential polarity changes of the electro-magnets to cause the feed cone to rotate in response to movement of paintballs in the feed tube.

  • Patent number: 8282269
    Abstract: A vessel in which a fluid is received and agitated by using an internal fluid-agitating element driven by a non-contact coupling with a motive device external to the vessel. In one aspect, the vessel is a bag including a first receiver for receiving and holding a fluid-agitating element at a home location. The first receiver may be in the form of an inwardly-projecting post having an oversized portion for capturing the fluid-agitating element, but various other forms are disclosed. In another aspect, the vessel or bag further includes a second receiver for receiving a portion of an external structure, such as a motive device, and aligning the vessel relative thereto. Related methods are also disclosed.

  • Publication number: 20110203515
    Abstract: A crystal growing cell which has computerized temperature control and agitation means to inhibit crystal nucleation. The temperature is controlled semi-actively, i.e., by monitoring the temperature with a thermistor and balancing ambient heat loss with heat added to the system by heating resistors or heating elements. When the chemical is completely dissolved by heating the mixture to a temperature above the saturation temperature, the temperature is lowered. At the saturation temperature the temperature is initially reduced slowly to avoid crystal nucleation. The saturation temperature of the initial solution is selected to be at an intermediate temperature which is high enough that the amount of dissolved material is large enough to produce a large crystal or large crystal clusters, yet not so high that the solubility curve has a large slope and therefore requires a high degree of temperature control to avoid crystal nucleation in the solution.

  • Patent number: 7879972
    Abstract: A method for drying a material such as a polymer hydrogel which passes through a cohesive phase as it dries is disclosed. The method comprises agitating a composition while removing liquid until the solids content of the composition reaches a level at which the composition enters a cohesive phase, halting agitation, removing liquid from the composition in the absence of agitation, and resuming agitation. Practice of the present invention can eliminate the problems associated with adhesion of a material to itself and to process equipment during the cohesive phase.
