Olusegun J. Ilegbusi has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Active magnetic flow control in Czochralski systems
    Patent number: 5196085
    Abstract: Improved Czochralski crystal growth apparatuses with bulk melt electromagnetic stirring and external axial magnetic fields selectively applied to a melt/growing crystal interface are provided. Such apparatuses are particularly well-suited for continuous feed growth processes.
    Type: Grant
    Filed: December 28, 1990
    Date of Patent: March 23, 1993
    Assignee: Massachusetts Institute of Technology
    Inventors: Julian Szekely, Olusegun J. Ilegbusi
  • Magnetic streamlining and flow control in tundishes
    Patent number: 4824078
    Abstract: A strong magnetic field, for example in the range of 500-50,000 Gauss, is applied across a tundish feeding continuous casting machines. The magnetic field, substantially perpendicular to the principal direction of flow within the tundish, provides very even flow in the tundish, uniform residence time and minimizes vortexing. The application of the magnetic field increases the percentage of inclusion particles removed from the melt during its residence within the tundish.
