Abstract: A switchable permanent magnetic unit is disclosed. The unit comprises: a housing, first and second permanent magnets, and a conductive coil. The first magnet is mounted within the housing and the second magnet is rotatable between first and second positions and mounted within the housing in a stacked relationship with the first magnet. The unit generates a first level of magnetic flux at a workpiece contact interface when the second magnet is in the first position and a second level of magnetic flux at the interface when the second magnet is in the second position, the second level being greater than the first level. The conductive coil is arranged about the second magnet and generates a magnetic field. A component of the conductive coil's magnetic field is directed from S to N along the second magnet's N-S pole pair when the second magnet is in the first position.

Abstract: The present invention relates to improvements in a magnetic featherboard, the featherboard having an elongate main body with opposite lateral faces, a bottom face and front and rear faces; a plurality of resiliently deformable feathers arranged at one or both lateral faces of the main body, and at least two, on-off switchable permanent magnets respectively received in one of at least two spaced apart recesses of the main body such that a working face of the respective switchable permanent magnet is present at the bottom face of the main body. One improvement comprises (i) providing a resiliently deformable friction gasket adjacent the working face of each of the switchable permanent magnets and protruding, in an non-deformed state, a predetermined amount from the bottom face of the main body and the working faces, the gaskets deformable through magnetic clamping of the featherboard to a table. The other improvement resides in providing at least two adjustable stops at one or both of the front and the rear face of the main body, each said stop comprising an abutment piece displaceable in longitudinal direction relative to the front/rear face, wherein a distance of each of the abutment pieces from the front/rear face is settable independently of each other, the stops operational to provide at least two abutments against which stock material to be machined can be placed when the featherboard is magnetically secured to the table.

Abstract: Magnetic coupling devices are disclosed which may be configured in at least three states. The various states may be provided through one or more of altering a position of a permanent magnet relative to another permanent magnet and altering a current level in a coil surrounding a permanent magnet.

Abstract: Method and device for self-regulated flux transfer from a source of magnetic energy into one or more ferromagnetic work pieces is provided. A plurality of magnets are disposed in a medium wherein gaps of predetermined distance are maintained between neighboring magnets. And the magnets we arranged such that magnetic flux exchange may take place between the magnets across the gaps and a ferromagnetic body in close vicinity or contact with the magnets.
