  • Patent number: 4301981
    Abstract: An aircraft is provided with a wing in the form of an annulus having an airfoil shape in radial section, the wing being concentrically mounted on a vertical axle shaft which in turn is rotatably carried by a mounting on the fuselage. Rotation of the wing drives air centrifugally across the upper and lower surfaces to energize the boundary layer, enhance laminar flow, and produce lift. Vanes may be mounted on the inner portion of the surface to increase the flow and thus produce greater life. The vanes may be attached to a stabilizer ring which is eccentrically adjustable by a controlling mechanism to vary the extension of the vanes into and out of the wing at various points in the cource of rotation and thus vary the degree of lift produced. The wing may also be provided within its inner perimeter with airfoil lifting blades which produce additional lift, and the blades may be swung by a stabilizer ring to positions producing a desired thrust in a desired direction as the wing rotates.

  • Patent number: 4276084
    Abstract: A hydrometallurgical process is used to recover lead from a lead-bearing ore concentrate. The lead-bearing ore concentrate is leached with a solution of cupric chloride in order to precipitate lead as lead chloride, produce elemental sulfur and substantially leave the balance of the ore concentrate sulfides in unreacted form. The residue of the cupric chloride leach is leached with a brine solution in order to solubilize the lead chloride to the exclusion of the balance of the residue. Thereafter, the lead chloride is crystallized from the brine solution. Elemental lead may be obtained by the reduction of the lead chloride crystals.The present process avoids air pollution problems inherent to smelting processes, allows for a high recovery of lead of 97% or greater and allows for the direct production of a high purity lead.
