    摘要： Metal cord for use in reinforcing fabric for articles made from rubber, such as pneumatic tires, conveyor belts, flexible tubes, and similar, comprising a plurality of such metal cords orientated parallel to each other in a single direction and in which each cord comprises metal wires wound spirally around each other, wherein at least one of the wires of the cord consists of a shape memory material. During the phase of incorporation of the cords into the elastomeric material, the shape memory wire tends to recover the shape memorized initially and, by means of the force generated during this recovery, transmits by friction to the surrounding wires forces tending to shorten the pitch of the cord with spacing of each wire from the next, resulting in good penetration of elastomeric material between the wires. The closure of the cord is maintained in the subsequent heat cycles, owing to the memory degradation characteristics imparted to the wire. The invention is particularly suitable for fabrics forming belt layers and casing plies in pneumatic tires.

    摘要翻译： 用于增强织物的金属帘线，用于由橡胶制成的制品，例如充气轮胎，输送带，柔性管等，其包括沿着单一方向彼此平行取向的多个这样的金属帘线，并且其中每个帘线包括金属 电线缠绕着彼此螺旋地缠绕，其中绳索的至少一根线由形状记忆材料组成。 在将电线并入弹性体材料的阶段期间，形状记忆线趋向于恢复最初记忆的形状，并且通过在该恢复期间产生的力通过摩擦传递给周围的电线力，趋向于缩短 电线与每个电线的间隔距离相近，导致弹性体材料在电线之间的良好穿透。 由于受到线的记忆降解特性，帘线的闭合在随后的热循环中保持。 本发明特别适用于在充气轮胎中形成带层和套层的织物。

    摘要： A tire includes a toroidal carcass and a tread band. The toroidal carcass includes a central crown and two sidewalls terminating in a pair of annular beads. Each annular bead includes a metallic bead core for anchoring to corresponding bead seats of a wheel rim. The metallic bead cores include at least one annular portion made of a material having characteristics of superelasticity and shape memory. The material having characteristics of superelasticity and shape memory is deformable at ambient temperature in response to a constant force and recovers to an original shape upon removal of the constant force to facilitate mounting the tire on the wheel rim. The wheel rim includes a central cylindrical channel from which branches off, axially and outwardly, from opposite sides, diverging surfaces each terminating in a peripheral flange. The diverging surfaces form the bead seats for respective annular beads of the tire.

    摘要： A method of mounting a tire on a rim includes selecting a tire comprising bead cores, stretching the bead cores, sliding the bead cores over a balcony portion of the rim, allowing the bead cores to elastically return to lengths corresponding to diameters of respective seats of the rim, and inflating the tire. The bead cores include one or more portions of material with characteristics of superelasticity and shape memory. Stretching the bead cores may include applying constant load to the bead cores at ambient temperature and/or causing the bead cores to undergo structural change at ambient temperature. The structural change may include complete or partial change from austenitic structure to martensitic structure. The one or more portions of material are deformable at ambient temperature in response to a constant force and recover to original shape upon removal of the constant force.

    摘要： A bead core for locking a tire to a seat of a wheel rim includes a plurality of annular reinforcement elements having an inner transverse dimension smaller than a maximum diameter of the wheel rim, and being sufficiently deformable at ambient temperature to facilitate mounting the tire onto the wheel rim. The plurality of annular reinforcement elements includes at least one tightening element made of a shape-memory alloy responsive to temperature increases by increasing a tightening force on the wheel rim at a predetermined temperature. A tire including the bead core and a method for securing a tire to a rim using the bead core are also disclosed.

    摘要： A noble metal tip 20 for attachment to a spark plug center electrode 36 and/or a ground electrode. Noble metal tip 20 is a generally cylindrical component that includes a firing end 40, an attachment end 42, and one or more retention features 44, 46 and 60, 62. The retention features are generally conically shaped holes or recesses formed in the side of the noble metal tip, and are designed to receive molten material during a laser attachment process. Once the molten material has solidified in the retention features, a fusion layer is formed and acts as a mechanical bond or interlock between the noble metal tip and the electrode. Methods of manufacturing and attaching the noble metal tips are also provided.
