Abstract: Apparatuses for coupling magnetic forces into motive force are disclosed having a spinner arm, a power bed, and a hub. The spinner arm has a helical array of magnets mounted about a shaft. The apparatus also has a rotational timing coupling such as a stationary rack and spinner shaft pinion. The power bed has two arrays of magnets defining a power track. The spinner arm shaft may be mounted in the hub, allowing rotation of the spinner arm about its axis. The hub is further constructed to allow the hub and spinner arm to move translationally within a plane parallel to a plane containing the power bed. High coercive force magnets in the spinner and power bed interact to displace the spinner arm and rotate it about its axis. Multiple spinner arms and power beds may be arranged to move a load linearly or drive a load about an axis.

Abstract: A holder for ferrous object, comprising: a holder body formed of a ferrous material and having at least one channel, the channel having a width and a depth; and a plurality of magnet members positioned in the at least one channel, the holder body and magnet members defining, in combination, a holding surface for magnetically securing ferrous objects.

Abstract: A magnetic tool holder includes a body portion having an elongate central portion defining a channel and having side edges laterally extending from the central portion in a plane; and a magnet member disposed in the channel and having a tool securing surface positioned in the plane.

Abstract: A magnetic retrieval tool, includes a magnet holder having a cylindrical wall having a rear portion and a front portion, the wall defining a space for holding a magnet, the wall decreasing in thickness from the rear portion toward the front portion, and a magnet disposed in the space, wherein the magnet holder concentrates flux from the magnet at the front portion.

Abstract: A magnetic head for a magnetic pick-up tool includes a magnet having a pick-up surface and a sleeve member having an open end and being slidably positioned over the magnet, the sleeve member being made of a material acted upon by the magnet such that the magnet exerts a force upon the sleeve for maintaining the sleeve in a rest position wherein the open end extends beyond the pick-up surface, wherein the sleeve is slidable in a direction away from the pick-up surface and against the force to a withdrawn with respect to the magnet. A magnetic pick-up tool including a magnet head is also disclosed.
