  • Patent number: 5085149
    Abstract: The improved support and guidance system includes a super conductor mounted in a vehicle and positioned to be above and on both sides of the upper end of a rail. The super conductor is provided with a housing and an iron core or shield is positioned within the housing to shield and shunt the return flux of the magnet so that the fringe field does not extend into the vehicle. In the preferred form of the invention, the rail in transverse section has an upper central flat surface with two concave surfaces extending to either side. The super conductors are positioned above and generally parallel to the concave surfaces of the rail. The iron shield has a horizontal central portion above the flat top of the rail and side bulbous portions on either side immediately above and to the side of the super conductors. The invention has application to the magnetic support and guidance system, the vehicle with the guidance system thereon and the combination of such vehicle with the rails.

  • Patent number: 4822772
    Abstract: A unitary superconducting electromagnetic structure (10) and method of forming same for use particularly at magnetic intensities greater than the magnetic saturation of iron and including an inner body (12) containing a coil pack (40) and an outer magnetic iron body (16) about the inner body (12) in concentric relation thereto. The outer body (16) has an end assembly (18) adjacent each end of the inner body (16) and the outer iron body (16) increases the magnetic field intensity at intensities substantially above the saturation of the magnetic iron in the outer body (16).The design of the electromagnetic structure (10) is based on a computer program which utilizes accurate information concerning the mechanical, thermal, electrical and magnetic properties of the materials proposed for the electromagnet including particularly the thermal and magnetic properties of the iron for predicting precisely the magnetic permeability of the iron at all values of the magnetic field.

  • Patent number: 4783628
    Abstract: A unitary superconducting electromagnet (10) especially adapted for use in medical or test apparatus with nuclear magnetic resonance (NMR) and spectroscopy at intensities above the magnetic saturation of iron so high as around ten (10) Tesla. The electromagnet (10) includes an inner generally cylindrical body (12) having a central bore (14) and an outer magnetic iron body (16) positioned concentrically about the inner body (12). One embodiment of the electromagnet (10) has adjusting blocks (110) secured to the inner body (12) for movement of the inner body (12) radially and longitudinally of the outer body (16) for precise positioning. Another embodiment shown in FIGS. 16-18 illustrates a small bore electromagnet (10A) having the inner body (12A) fixed relative to outer magnetic iron body (16A) with the outer body (16A) being exposed to the cooling fluid.
