Abstract: A ground breaking device comprises an elongated shaft having a length extending longitudinally from a proximal end to a distal end. The length is no greater than 7 feet and the distal end ends in a point. At least one stepping member extends out from the elongated shaft. The at least one stepping member has a longitudinal length along the shaft that is no more than 1/15 of the length of the shaft in the longitudinal direction. The at least one stepping member has a widened step of 1 to 5 inches and the shaft has a diameter between about 0.5? and 2?.

Abstract: A novel magnetic bearing assembly is disclosed where mutually repulsing magnetic fields are generated between an inner housing and an outer housing. In the preferred embodiment, these fields are located in pairs of cooperating rings, one set of rings having the generated field being axially aligned and the other set having a radial alignment. Thus, one section of the housing is suspended within the other without any contact.
