Optimization of superconducting tiling pattern for superconducting bearings

Hull, John R

Title: Optimization of superconducting tiling pattern for superconducting bearings

Abstract

An apparatus and method for reducing magnetic field inhomogeneities which produce rotational loss mechanisms in high temperature superconducting magnetic bearings. Magnetic field inhomogeneities are reduced by dividing high temperature superconducting structures into smaller structures, and arranging the smaller structures into tiers which stagger the magnetic field maximum locations of the smaller structures.

Superconducting microcircuitry by the microlithgraphic patterning of superconducting compounds and related materials

Patent Coppa, Nicholas V [Los Alamos, NM]

Superconducting microcircuits including a thin layer of Ba.sub.2 Cu.sub.3 O.sub.5+x (0<1) on a substrate. A thin layer of a dopant; for example, Y.sub.2 O.sub.3 for superconducting patterns of YBa.sub.2 Cu.sub.3 O.sub.7-x, or Pr.sub.2 O.sub.3 for insulator patterns of PrBa.sub.2 Cu.sub.3 O.sub.7-x. These layers are covered with a layer of photoresist, which is exposed to light through a mask having a pattern for a desired circuit. The photoresist is then developed to reveal a pattern of the thin dopant layer which will be etched away. The microcircuit is then etched and stripped to remove the unneeded portion of the thin dopantmore » « less

Levitation pressure and friction losses in superconducting bearings

Patent Hull, John R [Downers Grove, IL]

A superconducting bearing having at least one permanent magnet magnetized with a vertical polarization. The lower or stator portion of the bearing includes an array of high-temperature superconducting elements which are comprised of a plurality of annular rings. An annular ring is located below each permanent magnet and an annular ring is offset horizontally from at least one of the permanent magnets. The rings are composed of individual high-temperature superconducting elements located circumferentially along the ring. By constructing the horizontally-offset high-temperature superconducting ring so that the c-axis is oriented in a radial direction, a higher levitation force can be achieved.more » « less

Method and apparatus for measuring gravitational acceleration utilizing a high temperature superconducting bearing

Patent Hull, John R [Downers Grove, IL]

Gravitational acceleration is measured in all spatial dimensions with improved sensitivity by utilizing a high temperature superconducting (HTS) gravimeter. The HTS gravimeter is comprised of a permanent magnet suspended in a spaced relationship from a high temperature superconductor, and a cantilever having a mass at its free end is connected to the permanent magnet at its fixed end. The permanent magnet and superconductor combine to form a bearing platform with extremely low frictional losses, and the rotational displacement of the mass is measured to determine gravitational acceleration. Employing a high temperature superconductor component has the significant advantage of having anmore » « less

Method for obtaining large levitation pressure in superconducting magnetic bearings

Patent Hull, John R [Hinsdale, IL]

A method and apparatus for compressing magnetic flux to achieve high levitation pressures. Magnetic flux produced by a magnetic flux source travels through a gap between two high temperature superconducting material structures. The gap has a varying cross-sectional area to compress the magnetic flux, providing an increased magnetic field and correspondingly increased levitation force in the gap.
