20080216962 | Bead alignment clip and system for its use for locating and maintaining a tire bead positioning onto a tire core build man-drel in forming a core for manufacturing an elastomeric tire - The invention provides tire bead alignment clips for mounting onto each of a pair of tire beads have a U shape to fit over and clamp onto the tire bead that has received a plies sleeve end folded thereover and each tire clip is for magnetic attachment to each of a like number of spaced permanent magnets that are individually secured, at equal spaced locations, to points along radial arcs taken from a center of each of the sides of a cavity mold that are secured to opposite sides of a tire core build mandrel, and the permanent magnets are like horseshoe magnets having a pair of legs that each have north and south pole ends, and each bead clip side is magnetically attractive to couple to which permanent magnet ends, providing for attaching the plies sleeve ends and tire beads to optimum locations on opposite side of the cavity mold side inner surface and spaced apart from the tire core build mandrel that is for use in building a tire core to receive an elastomeric material directed therearound in a tire formation process. | 09-11-2008 |
20080230170 | Method for vacuum forming an elastomeric tire - A vacuum forming process for manufacturing a transport tire from an elastomeric material that include steps of: in a mold having a cavity or annular area, positioning a transport tire core of plies, belt and beads that has been laid-up on a mandrel. Fitting a cover in sealing engagement over the mold top and fitting a cylindrical canister, that is open at a top end, through the center of the cover and into the mold center and pouring an elastomeric material mixture into the canister that includes a needle valve in its lower end that exhausts into one end of the mold annular area. The cylindrical canister includes a port for connection to a deep vacuum source and the cover includes a port that is for connection to a low level vacuum source, where the deep vacuum is to remove air from the elastomeric material mixture, and, after filling, is open to atmosphere, and the needle valve is opened to the mold annular chamber allowing the mixture to be pulled by the low level vacuum through the mold annular cavity, impregnating the transport tire core maintained therein. | 09-25-2008 |
20080245482 | Belt for use in forming a core of plies, beads and belts of a urethane tire - A belt for incorporation into a core of plies and beads formed on a tire core build mandrel where the core is for encapsulating in an elastomeric material, preferably a polyurethane, in a tire formation process, and which belt is formed from like belt sections laid over one another where the one belt section is rotated approximately one hundred eighty degrees around its longitudinal axis with respect to the other, and the belt sections are individually mounted around a tire core build mandrel top whereover a plies has been fitted and with the pair of belt sections ends off-set from one another and are fitted together into a continuous belt. Each belt section is a weave of lateral and longitudinal cotton cords or filaments containing straight, spaced, parallel, taut, Rayon warp cords where the Rayon warp cords or filaments have a crossing angle of forty to sixth degrees respectively, with the stack of a two belt sections forming a tire belt. | 10-09-2008 |
20090071606 | Alignment system for positioning tire beads onto a tire core side wall - A combination of a plurality of equal spaced permanent magnets that are each fitted into a magnet cup formed into a cavity mold side outer surface that is immediately opposite to a slot formed around an outer edge of the inner surface of the cavity mold side, leaving a thin section of the cavity mold side material that separates the respective bottoms of the magnet cups from the bottom of the slot. The slot receives a tire bead whereover a tire plies is folded and is held in that slot by the attractive force provided by the permanent magnets, and pins are fitted at spaced intervals into, to extend outwardly from, the slot bottom surface to engage and center the tire bead in the slot. | 03-19-2009 |
20110041984 | Method and apparatus for retreading a heavy duty tire with a polyurethane tread - A method and apparatus for retreading a heavy duty tire with a polyurethane tread where, after a tire carcass is inspected for utility and is cleaned, the worn tire tread is removed and the carcass is reinspected to insure its suitability for retreading. The tire carcass, with a tube fitted therein, is installed on its side in a mold cavity, between top and bottom rings, that each include spaced segments extending from opposing top and bottom ring surface, and the segments inter-digitate and form the equal spaced tread voids in a finished recapped tire, and the bottom ring inner edge top includes a continuous lug for sealing against the tire side wall, and the top ring is open to pass a flow of polyurethane materials from a lower edge of a cone shaped spreader that is positioned onto the tire carcass top side wall and receives the flow of polyurethane materials directed onto the cone surface, the materials sliding as a sheet therefrom into the mold, filling the mold cavity from bottom to top, forcing air from the mold ahead of the fill, forming the recapped tire tread. | 02-24-2011 |
20120006470 | Method of Making a Bicycle Rim - A method of manufacturing a rim for a bicycle wheel includes wrapping plys of fibers in a resin matrix around a mandrel; curing the plys to form the rim; and reducing a size of the mandrel to allow the mandrel to be removed from the rim. | 01-12-2012 |
20130112333 | METHOD FOR RETREADING A HEAVY DUTY TIRE WITH A POLYURETHANE TREAD - A process and method for retreading a heavy duty tire with a polyurethane tread where, after a tire carcass is inspected, cleaned and the worn tire tread is removed, the tire carcass receives a tube fitted therein and is installed in a mold cavity, between top and bottom mold rings. The mold rings each include spaced segments that inter-digitate and will form equal spaced tread voids in a finished recapped tire. The bottom mold ring inner edge top includes a continuous sealing lug, and the top ring is open to pass a flow of polyurethane materials, that is received off of a lower edge of a cone shaped spreader positioned onto the tire carcass top side wall and slides, as a sheet, into the mold, filling the mold cavity from bottom to top, forcing air from the mold ahead of the fill and forming the recapped tire tread. | 05-09-2013 |
20150118051 | WIND SAIL RECEPTOR - An improved wind sail receptor for turning in a wind flow to turn an axle that operates a generator to produce an electrical power output for performing work. With the improved wind sail receptor blade design and the inclusion of a unique shape of nose cone fitted over a forward end of a housing that the wind sail receptor is journaled to, the wind sail receptor provides for a nearly one hundred percent utilization of the entering wind flow energy to turn the wind sail receptor blades. This near perfect wind energy utilization is provided by the structure of the blades leading and trailing edges along with the blades uniform curvature between leading and trailing edges that is from seventy to seventy eight degrees of arc and the nose cone configuration, whereby a turbulence free wind flow passed off of the blades trailing edge is at a approximately a forty five degree angle to the entering wind flow. | 04-30-2015 |
