Abstract:
A wind sail receptor for turning in a wind or flow of water, turning an axle that operates a power generator device that produces a power output for performing work or provides for passing that power output to a storage arrangement. The wind sail receptor preferably includes, from six to ten identical, equally spaced blades between a rear hub and a forward disk, with the rear hub and forward disk connected to an axle that is mounted to a frame through bearings, allowing the wind sail receptor to turn freely when it is pointed into a wind or water flow. Which wind sail receptor blades are formed from two sections of three to five equal spaced blades, and each section is formed from a single flat section of a stiff material, wherefrom radial sections have been removed to form the individual blades that are equal spaced around a hub, and which section hubs are fitted to one another and the blades bent into like curves, and outer blade ends are secured, at equal spaced intervals to a forward disk, forming the wind sail receptor.
Abstract:
A method and apparatus for forming a core of plies, belts and beads and for positioning the core in a mold for forming an elastomeric tire. The core is built up on a mandrel of the inner mold that is formed from hard foam core segments positioned between top and bottom hub plates, around a center hub that includes flow passages formed therethrough and through the hub plates. Plies for building the core are formed as a woven sleeve for passage along an expander cone and over the mandrel whereon a separator has been positioned, and a bead is passed over each sleeve end that receives a bead centering plate fitted through the sleeve, capturing the bead and positioning it on the mandrel side and provides for folding the plies end over the bead and up each mandrel side. Similarly, a belt or belts, formed as a weave of belt cords, is passed along an expander cone and onto the mandrel crown, with separators positioned between the mandrel, plies and belt or belts, and above a final belt, and a tire core is wound around the crown, from one side to the other.

A method and apparatus for forming a core of plies, belts and beads and for positioning the core in a mold for forming an elastomeric tire. The core is built up on a mandrel of the inner mold formed by hard foam core segments that are positioned on a bottom hub plate and around a hub fitted to the center of the bottom hub plate, and with a top hub plate fitted thereover in alignment with flow passages formed therethrough. Plies are first wound on a porous spacer, across the mandrel and the ply ends are folded around a tire bead and back upon themselves. Woven belt segments that form a belt whose cords form an angle of approximately twenty four degrees to the circumference and slope oppositely, are wound over a spacer wrap that has been applied over the plies outer circumference, and tire cord is wrapped over an outer spacer wrap. The inner mold and core are fitted in an outer mold and the assembly positioned in a casting well to receive a flow of an elastomeric material directed therein as the mold is spun up.
