  • Patent number: 8527063
    Abstract: A system to induce hyperthermia in a selected portion of the body utilizes permanent magnets mounted on a variable speed motor. A conductive button is positioned at a location proximate the target tissue to be heated, such as a tumor. The magnetic rotor assembly is positioned at a selected distance from the conductive button and rotated at a desired frequency to produce a changing permanent magnetic field that induces an eddy current on the surface of the conductive button. A temperature sensor may be positioned near the conductive button as a feedback mechanism to a control circuit. At higher magnetic polarity frequencies, the conductive button may be implemented in the form of metallic nanoparticles. In this embodiment, the nanoparticles may include molecular elements that selectively bind with the target tissue and thereby accumulate at the target tissue prior to the introduction of the rotating magnetic field.

  • Patent number: 6577037
    Abstract: In a magnetic coupler, a pair of magnet rotors is slidably mounted on rods. Ferrous material on the conductor rotors attracts the permanent magnets in the magnet rotors. Under static or relative static conditions, the attractive force urges the magnet rotors toward the conductor rotors to create a minimum, operational air gap therebetween. When there is a significant relative rotational velocity between the magnet rotors and the conductor rotors, a repulsion force urges the rotors apart. During start-up, latch arms retain the magnet rotors apart from the conductor rotors by a larger, soft-start air gap. During operation, centrifugal force moves the latch arms out of their active position. If the rotational speed of the load shaft decreases rapidly during operation, the magnet rotors move apart from the conductor rotors by a still larger, fully disengaged air gap.

  • Patent number: 6337527
    Abstract: A permanent magnet coupler has a conductor rotor assembly mounted on one shaft and a magnet rotor assembly mounted on a coaxial shaft. The magnet rotor assembly provides two magnet rotors spaced by the adjustable air gaps from two conductor elements provided by the conductor rotor assembly. The air gap adjustment includes adjustable stops, such, for example, as swing arms having an adjustable effective length. These stops operate in conjunction with swing arms causing the magnet rotors to move axially in unison in opposite directions. The air gaps are set so that the coupler will automatically release when subjected to an overloaded condition.

  • Patent number: 6072258
    Abstract: A cage carrying two axially adjustable conductors is mounted on one shaft and a rotor is mounted on a second coaxial shaft to occupy a position between the conductors. Permanent magnets on the rotor have poles spaced by air gaps from the conductors. The air gaps are adjusted by sliding the conductors toward and away from one another along slide members on the cage by use of adjustment units engaging the conductor rotors. Alternatively, the conductors can be mounted on the rotor, and the magnets can be adjustably mounted on the cage.

  • Patent number: 5909073
    Abstract: A magnetic coupling device has an electroconductive rotor presenting a band of electroconductive material and has a magnet rotor with permanent magnets which may be slide-mounted to move radially outward responsive to centrifugal force in opposition to a spring bias. When the magnet rotor is stationary the magnets are radially inward of the orbit of the electroconductive band, and when the magnets have moved outwardly when the magnet rotor is rotating, the magnets are spaced by an air gap from the electroconductive band so that eddy currents are induced in the band resulting in coupling of the rotors. In the alternative the magnets may be always at least partly opposite the electroconductive band. The electroconductive rotor preferably has two electroconductive bands positioned on opposite sides of the magnet rotor. One or both of the rotors may have sheaves mounted thereon.

  • Patent number: 5903075
    Abstract: The soft start of a permanent magnet coupler of the type in which magnetic flux from permanent magnets on a rotary magnet rotor bridges an air gap between the magnets and an electroconductive element on a rotary conductor rotor to magnetically couple said rotors together responsive to relative rotary motion between said rotors, is adjusted by changing the amount of flux which bridges the air gap. This is accomplished by attracting some of the flux to magnetic material selectively positioned on said magnet rotor adjacent one or more of said magnets.
