  • Patent number: 6376959
    Abstract: A mangle magnetic structure is composed of a plurality of transversely magnetized parallel cylindrical rods forming a cylindrical shell defining an interior cavity filled with insulated wires in parallel to the mangle's principal axis. Two semicircular sections composed of the solid copper wires, within the interior cavity, are physically separated and insulated from each other by a barrier. The transversely magnetized parallel cylindrical rods are rotatable around each rod's individual axis, causing an interior magnetic field within interior cavity and the semicircular sections. The transversely magnetized parallel cylindrical rods are rotated so that the lines of force emanating from them produce an Alternating Current axial electromotive force to drive current through the semicircular sections and to an external load. In one embodiment, two sets of concentric transversely magnetized parallel cylindrical rods form the magnetic shell.

  • Patent number: 6320488
    Abstract: A permanent magnet structure that produces a working magnetic field having a field-strength that can be mechanically adjusted. In general, the permanent magnet structure includes at least four permanent magnet shells that are assembled such that the magnetic fields they produce interact with each other in a working space to form the working magnetic field. Two of the four permanent magnet shells are magnetized such that they interact to produce a magnetic field (a first field) in the working space. The other two permanent magnet shells are magnetized such that they interact to produce a magnetic field (a second field) having a given field strength in the working space. The first and second fields interact in the working space to form the working magnetic field. Further, the four permanent magnet shells are arranged such that the relative position of each shell with respect to the other shells can be changed by mechanically moving any one of the shells.

  • Patent number: 6304017
    Abstract: The nested magic cylinders are rotatable and coaxially arranged so that the bore of the inner cylinder provides a central working space. The predetermined magnetic orientation of each cylinder's sections is arranged to create a relatively strong and uniform magnetic field within the central working space or bore in which copper wires are imbedded to form a core. A core having copper wires embedded within the working space is coaxially positioned within the bore to act as a rotor and when current flows within the copper wires an electric motor is therefore formed. Alternatively, a rotating device can mechanically rotate the rotor or core, inducing a current in the copper wires in the rotor or core thereby forming an electric generator. The sections of the nested permanent magnet cylinders are arranged such that each of the sections have a magnetic orientation forming a pair of coaxial “magic” cylinders or rings that counter rotate with respect to each other.

  • Patent number: 6087915
    Abstract: A magic sphere having an equatorial gap, with a radial magnetic field in equatorial gap. The radial magnetic field can flow inward, toward the center of the magic sphere, or outward, away from the magic sphere. In a further embodiment, the magic sphere produces a periodically radial magnetic field. In another embodiment, a magic sphere with an azimuthally periodic radial magnetic field that flows in the outward direction periodically magnetizes a magnetically hard ring in the outward direction. Then, a magic sphere with an azimuthally periodic radial magnetic field that flows inwardly, periodically magnetizes the ring in the inward direction. The result is a permanent magnet that has a radial magnetic field, where the direction of the field periodically alternates from the inward to the outward direction.

  • Patent number: 6054789
    Abstract: An electric motor or generator having a permanent magnet cylinder or stator comprised of a plurality of sections with each section having a predetened magnetic orientation so as to create a relatively strong interior working space having a relatively strong magnetic field or flux therein. A cylindrical core formed of copper wires or conductors imbedded in a magnetic material is placed within the interior working space of the permanent magnet cylinder so as to be free to rotate along a longitudinal axis or in relation to the permanent magnet cylinder. Upon application of a current to the copper wires or conductors within the core, the core is caused to rotate or move in relation to the permanent magnet cylinder, forming an electric motor. Alternatively, when the core is mechanically rotated or moved in relation to the permanent magnet cylinder, current is induced in the conductors in the core, generating electricity.

  • Patent number: 5945899
    Abstract: A permanent magnet rectangular bar shaped to form a helix having a central ore and a longitudinal axis. The magnetic orientation of the helical permanent magnet bar is along the longitudinal axis forming a transverse helical magnetic field. An electron beam or charged particle passing near the longitudinal axis experiences acceleration causing the charged particles to radiate creating a high energy radiation source. In another embodiment, first and second permanent magnet helical bars are intertwined together, forming a cylindrical tube, with each of the intertwined helical bars having a magnetic orientation along the longitudinal axis in opposing directions. In another embodiment of the present invention, an iron ribbon or other high permeability magnetic material is interposed between cut-out portions between first and second intertwined helical permanent magnet bars. This effectively augments the transverse magnetic field.

  • Patent number: 5909165
    Abstract: A Chiron Twister magnet structure is provided from a right circular cylinder constructed of a passive material, such as iron, formed into a continuous helical bar deployed around a tunnel-like working space, in which it produces a transverse helical magnetic field, and through which a charged particle beam is sent by an electron beam means, causing the electrons to move in a helical pattern. The continuous helical bar is coupled to an external magnetic field means. The continuous helical bar has a substantially rectangular cross section, with a plurality of south poles opposed by a plurality of north poles. The continuous helical bar may be constructed of a circular right cylinder, such as a pipe, made of iron, or any other high saturation passive magnetization material.

  • Patent number: 5805044
    Abstract: A low-loss magnetic structure that provides an electron beam focusing field that can be accessed without field reversal. More specifically, the structure provides a uniform magnetic field that can be accessed from an adjacent field-free chamber within which an electron beam source of any size can be housed. The field-free chamber is separated from uniform field by a passive ferromagnet having a hole through which the electron beam can pass. The passive ferromagnet is instrumental in preventing the uniform field from entering the field-free chamber.

  • Patent number: 5705064
    Abstract: A magnetic particle separator for separating such things as ore or blood is ade from a permanent magnet structure which has a plurality of segments combined to form a cylinder. Each of said plurality of segments has a magnetic remanence and direction that varies so as to form a transverse magnetic field gradient within the bore of the cylinder. A pipe is placed within the bore of the cylinder for transporting a material that is to be separated. An output end of the pipe has a transverse divider or web separating the pipe into a region near the lower magnetic flux density in the magnetic field gradient and a region near the higher magnetic flux density in the magnetic field gradient. Because of the magnetic field gradient within the bore of the pipe, the particles, having a magnetic moment or dipole, are caused to drift toward the higher magnetic flux density end of the magnetic field gradient.

  • Patent number: 5666098
    Abstract: A permanent magnet toroidal structure having a periodic or modulated tranrse magnetic field with an average magnetic field greater than zero providing containment for an electron beam. In one embodiment, permanent magnet toroidal sections having a magnetic orientation for producing a transverse magnetic field are spaced in a toroidal shape. A periodic or modulating magnetic field of a single direction is thereby formed. The magnetic field is stronger over the permanent magnet toroidal sections and the magnetic field is weaker, but of the same direction, in the spaces between the permanent magnet toroidal sections. The repetitive acceleration of electrons traversing the arc of the toroidal structure creates electromagnetic radiation. A core is placed within the cavity or working space of the toroidal structure. The core is made of either a permanent magnet material or a ferromagnetic material.

  • Patent number: 5666097
    Abstract: A magnetizer for use in forming periodic magnetic fields is provided which utilizes two magnet structures which are coaxially aligned with one another. Two stages of magnetic cores are inserted into a gap between the two magnet structures. The stages of magnetic cores each have an upper and lower portion, each portion of which has grooves and ridges which mirror each other. The two different stages of magnetic cores are fabricated such that the respective grooves and ridges are offset and the grooves and ridges of one stage of magnetic core opposes the grooves and ridges, respectively, of the other stage of magnetic core. The two stages of magnetic cores can be active or passive magnetic material. In operation, the two magnetic structures form a uniform transverse magnetic field which passes through a working cavity of the magnetizer.
