1. A process for bidirectionally interconverting linear and rotary motions, said process comprising the steps of:

  • producing a rack consisting of a cross-sectionally curved tape and thereby having a convex surface, and said rack capable of being bent toward said surface and radially forming a convex bend;

    producing circular means for supporting said rack bent convexly thereon, and said circular means forming a diameter;

    producing at least one wheel having sprockets, and said at least one wheel forming a diameter, and said sprockets having tangencies forming a diameter, and producing said diameter of said at least one wheel smaller than said diameter formed by said circular means, and producing said diameter formed by said tangencies larger than said diameter formed by said circular means;

    producing rotatable axial means and coaxially aligning said circular means and said at least one wheel having sprockets with said axial means;

    providing means supporting said axial means;

    producing machinery for perforating said rack, and said machinery adjusting said rack whereby each perforation in said rack is made perpendicular to said rack while said rack is bent corresponding to said rack being bent about said circular means;

    producing with said machinery at least one row of perforations in said rack, and said perforations being sized smaller than said sprockets, spaced to mate with said sprockets, and disposed along at least one side of said rack;

    bending said rack containing said perforations toward said surface, and arranging said bend about said circular means whereby said perforations in said bend project beyond said circular means;

    arranging said at least one wheel having sprockets whereby a number of said sprockets partially penetrate said perforations projecting beyond said circular means;

    wearing and thereby mating said perforations with said sprockets by alternately retracting opposite ends of said rack, and thereby rotating said sprockets with causing said surface being laterally flattened to contact said circular means, and said at least one wheel having sprockets being mated thereby rotatably adjusting with said at least one row having perforations being mated;

    fastening said circular means and said at least one wheel having said mated sprockets to said axial means; and

    longitudinally moving said rack, and said rack rotating convexly on said circular means, and said mated perforations at said bend falling upon, mating with, rotating with and rising from said mated sprockets thereby interconverting linear motions of said rack with rotary motions of said mated sprockets.
