Patent number: 8621987Abstract: A cooking skillet that provides a unique automatic stirring system for continuously stirring foods during cooking. The cooking skillet comprises a base, a receptacle, a heating element, and an automatic stirring system. The automatic stirring system comprises a stirring wand located in the receptacle and a bracket located in the base. The stirring wand and the bracket are attracted to each other through magnetic forces that provide sufficient magnetism to attract one to the other. A motor is attached to the bracket by a connecting rod and provides the means to rotate the bracket in a clockwise direction. The magnetism between the magnets in the bracket and the magnets in the stirring wand forces the stirring wand to rotate in connection with the bracket. During rotation, the stirring wand is designed to mix the food contained within the receptacle.Type: GrantFiled: April 22, 2013Date of Patent: January 7, 2014Inventor: Walter B. Herbst

Publication number: 20130155803Abstract: The stirring apparatus is an electronic design that generates rotating magnetic fields to drive magnetic stir bars within vials placed above the cover of the stirring apparatus. Below the cover is a magnetics board containing multiple vial groups of four air core coils arranged in rectangular patterns. Each vial group has with two pairs of diagonal coils. The coils in each pair are wired in series and have opposite winding directions. Each pair is driven by a different phase of a stepper motor driver. The vial groups are spaced appropriately for placing one vial above each group. The adjacent coils of adjacent vial groups are driven by the same phase and have the same magnetic direction. The cover contains an array of pole standoffs that matches the coil pattern. The hollow center of each air core coil contains at least a portion of one pole standoff.Type: ApplicationFiled: February 11, 2013Publication date: June 20, 2013Applicant: GENERAL ELECTRIC COMPANYInventor: GENERAL ELECTRIC COMPANY

Patent number: 8459245Abstract: 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 independently 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 a predetermined amount for each polarity cycle and cause paintballs to be fed into the paintball marker via a feed tube. A controller linked to the marker firing sequence manages the number and frequency of the sequential polarity changes of the electro-magnets to cause the feed cone to rotate in response to sensed movement of paintballs in the feed tube.Type: GrantFiled: October 9, 2012Date of Patent: June 11, 2013Inventors: Michael J. Fiorill, Donald Lee Kulp

Publication number: 20130114370Abstract: A magnetically-driven stirring structure includes a transmission base, and a cup can be mounted to the transmission base or positioned on the transmission base. The transmission base includes a rotary mechanism, and the rotary mechanism is coupled to a first magnetic member. The rotary mechanism is coupled to an operating member in such a way that the operating member is exposed outside the transmission base. With a second magnetic member being placed in the cup, in making or brewing a drink in the cup, through actuation caused by the operating member, the rotary mechanism is made rotating and driving the first magnetic member to rotate, whereby the second magnetic member placed in the cup is caused by magnetism to rotate in the same direction so as to achieve stirring of the drink contained in the cup.Type: ApplicationFiled: November 8, 2011Publication date: May 9, 2013Inventor: PEI-CHUAN MA
