Abstract: The present invention is a tension braced dome structure comprised of a top ridge having at least one upper ridge radial member and at least one circumferential member which is concentric with an edge member; wherein the upper ridge radial member and the circumferential member are capable of carrying compressive and tensile loading; and further comprising a tensegrity grid having at least one diagonal member, and at least one lower compression member, and at least one lower cicumferential member; wherein said diagonal member extends between the upper ridge radial member and the compression member; and still further having a means for resolving internal stresses as an integral part of the top ridge; and a means for adjusting tension in the diagonal member.

Abstract: A unit guide wear plate which aligns the movement of a brake beam end guide within the side frame of a railroad car truck so that the brake shoes can provide the maximum amount of force against the wheels when stopping the railroad car.

Abstract: A component carrying case has a plurality of individual storage compartments that are covered by sliding transparent sheets. An interior component box which also contains individual storage compartments with sliding covers lies within the case and is attached to a three-leaf hinge configuration that enables the interior component box to swivel from one side of the case into the other without interfering with the opening or closing of the case.

Abstract: This invention relates to a saw for cutting remote tree limbs or other wood pieces from ground level. The saw consists of a segment of a standard chain saw blade attached to ropes held by the operator in each hand. An apparatus for lifting one end of the saw over the workpiece is also disclosed. Proper placement of the saw blade on the workpiece is facilitated by use of roller beads, to minimize snagging, and a tipping device that ensures proper orientation of the saw blade. Handles are attached to the rope ends for ease in operation.

Abstract: A gold based alloy containing gold, silver, copper, zinc, silicon, iron, boron, nickel and indium for the manufacture of gold articles is described which has a lower melting point, extended remelting capabilities, high resistance to cracking, improved color consistency and increased ductility.

Abstract: The present invention is an energy-storing bicycle sprocket drive system which includes a crank which rotates a shaft about the shaft's longitudinal axis. The crank moves through a point of minimum applied leverage and a point of maximum applied leverage in each rotational cycle. Journalled to the shaft is a drive plate having an outer surface with at least one opening. Each opening has an inner surface with at least one end wall. Facing the drive plate is a wheel which rotates freely on the shaft. At least one drive peg is mounted to the wheel such that it is in a position parallel to the longitudinal axis of the shaft. The drive peg extends from the wheel and into the opening of the drive plate. A spring is mounted within the opening between the end wall and the drive peg. As the shaft rotates and the spring is in a compressed state, it stores energy while exerting a first force on the drive peg causing the wheel to revolve as the crank rotates 90 degrees from the point of maximum applied leverage.

Abstract: A portable carrier for containing, using and displaying blueprints in an outdoor working environment includes an expandable living hinge along the centerline of a planar folio with integral handles and closure devices specifically configured restraining clamps to lock large-sized blueprints in place. The folio can thus be laid flat or posted on a wall for use in the field or folded and carried in convenient fashion using the closures and the handles and closure.
