  • Patent number: 7316502
    Abstract: A blade for mixing a material includes a disk comprising a plastic or composite material. The disk may have one or more circumferentially-spaced openings extending through the disk from a substantially flat top surface to a substantially flat bottom surface. The openings are located at a common radial distance from a center of the disk. The disk may be made from a plastic material such as nylon, TeflonĀ®, polyethylene, polyurethane, polyvinyl chloride, or combinations thereof. The disk may also have one or more sets of mixing teeth extending outwardly from a circumferential edge of the disk. A blending apparatus includes one or more of the disks mounted on a rotatable shaft.

  • Patent number: 7167675
    Abstract: A magnetic switch and children's apparatuses, such as print media apparatuses and plush dolls, which include magnetic switches are disclosed. One magnetic switch includes a first conductor and a second conductor spaced apart from the first conductor. A third conductor is disposed under the first and second conductors, the third conductor being formed from a magnetic material. A magnet is also included, the magnet being adapted to move the third conductor towards the first and second conductors so as to form a conductive bridge. Another magnetic switch includes a first conductor and a second conductor spaced apart from the first conductor. A first magnet is disposed under the first and second conductors. A second magnet is also included, the second magnet being adapted to move the first magnet so that the first and second conductors form a conductive bridge.

  • Patent number: 7096794
    Abstract: A simple permanent-magnet-excited maglev geometry provides levitation forces and is stable against vertical displacements from equilibrium but is unstable against horizontal displacements. An Inductrack system is then used in conjunction with this system to effect stabilization against horizontal displacements and to provide centering forces to overcome centrifugal forces when the vehicle is traversing curved sections of a track or when any other transient horizontal force is present. In some proposed embodiments, the Inductrack track elements are also employed as the stator of a linear induction-motor drive and braking system.

  • Patent number: 6664880
    Abstract: A magnet configuration comprising a pair of Halbach arrays magnetically and structurally connected together are positioned with respect to each other so that a first component of their fields substantially cancels at a first plane between them, and a second component of their fields substantially adds at this first plane. A track of windings is located between the pair of Halbach arrays and a propulsion mechanism is provided for moving the pair of Halbach arrays along the track. When the pair of Halbach arrays move along the track and the track is not located at the first plane, a current is induced in the windings and a restoring force is exerted on the pair of Halbach arrays.

  • Patent number: 6546384
    Abstract: A format structure for storing retrievable data on a sequential data storage medium, which includes in an exemplary embodiment a start field for indicating the start of a data file, an index field for storing indexing data respecting the data file, and a data field. Stored encoded data on the storage medium can use the last file written on the storage medium to create indexing data that can be stored alongside the data files as they written so that each sequential data storage medium remains fully indexed.
