Abstract: A pneumatic tire includes a carcass reinforced by a carcass ply, at least one belt ply disposed radially outward of the carcass ply in a crown portion of the pneumatic tire, and at least one overlay ply disposed radially outward of the belt ply in the crown portion of the pneumatic tire. The overlay ply includes at least one composite cord having at least one first core yarn with at least one second outer metallic filament wrapped around the first core yarn such that the first core yarn has a modulus less than a modulus of the second outer metallic filament. The first core yarn has a diameter in the range between 0.012-0.035 inches and a twist in the range between 5-15 TPI. The second outer metallic filament is twisted about the first core yarn between 3-14 TPI.

Abstract: A composite conductor assembly is configured as a core composed of polymeric elastomeric material and a conductive layer in intimate surrounding contact with the core. The polymeric material provides elasticity to the core to enable the core to elongate when subjected to strain forces within a tire. The conductive layer is fabricated from a low impedance material and may be configured as a composite wherein an inner base metal is selected as a strength member and an outer metallic layer is applied to the base for electrical performance enhancement.

Abstract: A wire drawing machine includes a frame; at least one die operatively supported by the frame; at least one drawing block rotatably supported by the frame for use in drawing wire through the die; and, a motor for use in providing power. A belt system connects the motor to the drawing block so that the drawing block can be rotated. To adjust the speed and torque of the drawing block, the belt is removed and one sprocket is replaced with a second sprocket.

Abstract: An antenna system and method for tire monitoring systems provides an elasticized substrate in combination with an antenna wire(s). The antenna cable can be wrapped around or otherwise applied to the elasticized substrate, preferably in a wave or sinusoidal configuration. When subjected to forces of external origin, the substrate can elongate while the antenna wire straightens. Upon release from the influence of such forces, residual spring forces within the elasticized substrate relax and return the substrate and the antenna cable carried thereby back to its original, optimal configuration. The pitch of the antenna material on the substrate may be customized to suit the needs of the particular tire and communication. The antenna may be sewn or woven into the elasticized fabric, helically wound around a core composed of such material, or attached in an alternative manner.

Abstract: An antenna system and method for tire monitoring systems provides a flexible conductor having sufficient elongation characteristics as an antenna in a tire monitoring sensor system. A conductive strand is formed by wrapping a conductive tinsel ribbon around an extensible strength member. One or more conductive strands are combined to form an antenna cable that affixes to the inner liner of a tire. According to one aspect of the invention a conductive strand is formed by spiral wrapping at least one conductive tinsel ribbon around the strength member. According to another aspect of the invention, multiple tinsel ribbons may be wrapped around the strength member in braided fashion.

Abstract: An antenna system and method for tire monitoring systems provides a tubular antenna housing composed of suitably flexible material. An antenna is placed within the housing in either a straight configuration or a preferred alternative shape such as sinusoidal. The tubular housing may be straight walled or corrugated for additional flexibility. The electronics package may be provided with opposite ends dimensioned and configured for mating engagement with opposite ends of the antenna tube. Mating engagement between the electronics housing ends and the antenna tube ends secure the antenna tube to the electronics package. Subsequently, the antenna system may be secured by adhesive or other known techniques to the tire inner liner.

Abstract: An acid plating bath and an improved process for electrodepositing level copper coatings are described. The improved copper plating baths and method include a bath soluble organic leveling compound which is obtained by reacting one or more epihalohydrins with one or more nitrogen-containing compounds which may be substituted pyridines, quinolines, isoquinoline or benzimidazole. Particularly improved results are obtained if the acid copper bath also contains, in addition to the leveling agent, a bath-soluble brightening agent and a wetting agent. The presence of the above-described leveling agent in acid copper plating baths produces a lustrous, smooth and level deposit of copper over a wide range of current densities.
