  • Patent number: 6176471
    Abstract: A fabric fence system and method of manufacturing the fabric fence system is disclosed. The fence system has posts that are laterally spaced from one another with a fence fabric position between the posts. The fence fabric has end protrusions that are inserted into the sides of the fence posts and held in place by a rod inserted into the hollow inner portion of the post such that the rod engages the protrusions of the fence fabric. The slots that accommodate the fence fabric are set at an angle relative the length of the post. The fence system also includes top and bottom cross members into which the top and bottom portion of the fence fabric are inserted and attached to provide a panelized fence system.

  • Patent number: 4456858
    Abstract: Disclosed is a rotary machine powered by magnetic fields and comprises at least one fixed and at least one movable permanent magnetic member which have a curvilinear surface adapted to provide mutually eccentric magnetic fields and which operate to rotate the movable member with respect to the fixed member until a magnetic equilibrium position is reached, at which time means are included to rotate the movable member away from the equilibrium position, whereupon the eccentric fields again interact to cause rotation. The curvilinear surfaces are in the form of a spiral which expand in an arithmetic or geometric progression and are poled to provide alternatively either attractive or repulsive forces between opposing faces of the magnetic members.
