Abstract: A composite material comprises a plurality of springs forming a structure embedded within a polymer. Each spring is interwoven with at least one other spring thereby forming an entirely polymer-coated structure.

Abstract: Tire vulcanizing/retreading and de-vulcanization system including an autoclave and heating based on an induction system, which will lead to vulcanization or de-vulcanization of a tire.

Abstract: A process for devulcanizing crosslinked elastomer particles comprising applying an alternating electric field to a composition comprising crosslinked elastomer particles under compression. The alternating electric field preferably has a frequency between 1 and 100 MHz and a voltage between 1000 and 10,000 V, and may be applied between an apparatus that continuously conveys the particles through the field.

Abstract: A process for devulcanizing crosslinked elastomer particles comprising applying an alternating radio frequency dielectric field to a composition comprising crosslinked elastomer particles. The alternating radio frequency dielectric field preferably has a frequency between 1 and 100 MHz and a voltage between 1000 and 10,000 V.

Abstract: A puncture resistant pneumatic tire has a tread portion and a pair of lateral tread edges. A belt package is located radially inward of the tread portion and a carcass structure has at least one body ply which extends between and is turned up around a pair of bead cores. A protective band extends circumferentially about the tire radially beneath the tread portion and includes a plurality of circumferentially spaced metal rods, each of which extends in a lateral direction between the tread edges. The protective band may be located radially inward or outward of a spiral ply layer and the rods may be arranged in a staggered laterally offset layered relationship. The rods have a circular cross-section with a diameter of between 1/16 inch and ¼ inch and a length of between 7 inches and 8 inches and will deflect and dislodge the pointed end of road debris before it completely punctures the tire.

Abstract: The invention herein relates to an improved tire structure comprised of a plurality of thin steel plates crisscrossingly arranged in the thick portion of a tire surface and an assembly of cover tire installed around the surface of said tire; the plurality of up and down crisscrossingly arranged thin steel plates form a shield along the circumference of tire that removes the worry of the tire being punctured by sharp objects on the roads when the vehicle travels, thus enhancing driving safety; the cover tire can be replaced after it is worn out without the need to change the whole tire, thus effectively reducing the consumption of rubber for tire production that makes the invention herein both economical and environmentally friendly.

Abstract: The tires for vehicles possess under their tread a belt which extends in the circumferential direction. At least one, preferentially two, layers contain, as strengthening and stabilizing means, foils or sheets with direction-dependent rigidity, which possesses its highest value in a preferred direction. The foils or sheets are so arranged that the preferred direction is oblique to the circumferential direction. Preferentially, the direction-dependent rigidity is realized with a waving or crimping. Through this alignment, which is arranged oblique to the tire circumference, the stabilizing effect of the waving is seen in both the longitudinal as well as the oblique directions. Thus, in comparison with the usual belted tires, less material is needed in tire production, and these tires are both light, but nevertheless possess good driving characteristics and superb rolling resistance.

Abstract: The invention relates to a tire formed of a plurality of independent pneuic sectors (S) intended to be mounted on a single rim (J) but removable individually from said rim (J), they being inflatable individually or together. The sectors (S) include at least one reinforcing armoring (4) anchored on at least one circumferential bead wire (10) in each circumferential bead, which is the bead mounted on the wheel rim (J), the reinforcing armoring (4) being radially adjacent to a reinforcement armoring (8) of the tread (2). The circumferential bead wires (10) are connected to meridian bead wires (11) located in the sidewalls (50) of the circumferentially adjacent sectors (S).

Abstract: A cut resistant pneumatic tire is provided. The tire has a monofilament wire structure embedded in or under its tread or sidewall, and is used in off the road applications such as mining. The monofilament wire has a diameter of 0.4 to 1.2 mm and is made of brass plated steel. The wire may be woven or may have a spring link configuration. Two monofilament wires may be twisted together, and when two such wires are used, the total diameter is 0.8 to 1.4 mm.

Abstract: The tripartite crown reinforcement of this tire is subdivided into a median portion composed of two plies of cables whose extensibility is practically zero, flanked by two lateral portions each composed of three plies of cables whose extensibility is very great. When this tire is not inflated, the edges of its tread resume the falling shape which has been imparted to them in the vulcanization mold.
