  • Vector kerr magnetometry
    Patent number: 6501269
    Abstract: A system and method for realizing vector Kerr magnetometry are disclosed. The system enables simultaneous longitudinal and transverse Kerr effect measurements at each point on a sample surface. An optional component includes a sample platform for achieving precise linear and rotational relocation. The repositionable platform enables complete, 360 degree characterization about a single point. Additionally, the platform control mechanism may be utilized in obtaining longitudinal and transverse Kerr effect measurements at succeeding points on the surface of a sample. Rapid sample characterization is thus achieved.

  • Equipment for the delivery of slurries and for refinement during delivery
    Patent number: 4361414
    Abstract: The invention relates to an equipment for the delivery of slurries and for their refinement during delivery, which has a housing provided with axial inlet opening and tangential discharge opening, furthermore a disc-shaped stationary part in the housing with a concentric opening adjoining the inlet opening, and disc-shaped rotary part arranged opposite the stationary part. Rods are concentrically arranged according to the invention alternately on the stationary part and rotary part in such a way, that the rods of the stationary part point toward the rotary part, and the rods of the rotary part point toward the stationary part, and the rotary part has a jacket surrounding the rods arranged along the largest diameter circle of the stationary part, said jacket being perforated with holes in radial direction.
