  • TURBINE GENERATOR HAVING DIRECT MAGNETIC GEAR DRIVE
    Publication number: 20100032952
    Abstract: A turbine operated electric generator includes a turbine and a magnetic gear unit rotationally coupled at an input thereof to at least one of an inner rim of the turbine and an outer rim of the turbine. An output of the magnetic gear unit is configured to operate an electric generator. The magnetic gear unit includes magnets configured to at least one of increase a rotation speed at the output with respect to the input speed and inversely change a torque at the output with respect to the input and decrease the output speed with respect to the input speed and inversely change the torque.

  • Method and apparatus for magnetic separation of particles
    Patent number: 7258799
    Abstract: A magnetic circuit is shaped to generate an essentially uniform magnetic field parallel across the length of a container, and an essentially uniform magnetic field gradient along the length of the container as well. The dot product of the magnetic field and magnetic field gradient, known as the relative force density, is substantially uniform over the entire container, thereby causing particles to uniformly separate throughout the container.
