A repair patch for an elastomeric element, particularly for a vehicle tire, use thereof and method for bonding a repair patch to an elastomeric element. The repair patch (1) comprises: a top layer (10), a bonding layer (30) for covering a wall (80) of the elastomeric element (40), and at least one intermediate layer (20) arranged between the bonding layer (30) and the top layer (10), wherein prior to vulcanization with the elastomeric element (40), the bonding layer (30) has a first and a second natural rubber component, wherein the first natural rubber component has a lower molecular weight Mw than the second natural rubber component, such that a mixture of the first and second natural rubber components has a bimodal molecular weight distribution.

A compressor assembly (10) for supplying pressure medium to a tire cavity (7) of a tire of a vehicle wheel, which can be mounted on a wheel hub (4) that is mounted on a wheel carrier (3) for rotation about an axis of rotation (32). The compressor assembly (10) includes a hub-side compression chamber (16) and a compressor component (18). A pressure medium is conducted into the tire cavity (7) upon being pressurized in the compression chamber (16) by oscillating translational motion of the compressor component (18). The compressor assembly (10) includes a transmission (20) that converts a rotational motion between the wheel carrier side and the wheel hub side into an oscillating translational motion of the compressor component (18) when a hub-side transmission part (24) is in an operating position with a wheel-carrier-side transmission part (26).

Disclosed herein are kits for use in adding degradable foam to a tire, methods for preparing a degradable foam-containing tire, tires containing degradable foam, and methods for degrading the degradable foam in tires containing degradable foam. The degradable foam comprises a combination of (i) at least one di- or polyisocyanate, (ii) at least one polysiloxane diol, at least one polysiloxane diamine, or a combination thereof, and (iii) optionally at least one polyol.

A method for repairing a tire is provided that includes: (a) providing a reamer, a knife, an insertion tool forming a receiving opening, a plugging strip, and vulcanizing fluid; (b) inserting the reamer into a puncture hole of a tire to clear debris; (c) applying the vulcanizing fluid; (d) inserting the plugging strip into the insertion tool; (e) inserting the insertion tool with the plugging strip into the puncture hole to cause the plugging strip to fold into the puncture hole mixed with the vulcanizing fluid to bond the plugging strip and the tire; (f) removing the insertion tool from the puncture hole causing a middle portion of the plugging strip to fold internally forming a four-layer seal within the puncture hole; and (g) cutting the plugging strip from the insertion tool and the excess portions of the plugging strip with the knife.

The invention relates to a process for devulcanizing a vulcanized rubber mixture, comprising the following steps: A) providing or producing a vulcanized rubber mixture, B) comminuting the vulcanized rubber mixture into a granulate of vulcanized rubber particles, C) extruding the vulcanized rubber particles produced in step B) in a twin-screw extruder to form a devulcanized rubber mixture, wherein, during the extruding in step C) at least one regeneration reagent is added to the extruded rubber particles, wherein the regeneration reagent comprises at least one silane, at least one plasticizer, at least one aging stabilizer or mixtures thereof. The invention also comprises an apparatus for performing the method and the uses of the apparatus, and a rubber mixture and also a pneumatic vehicle tyre or a technical rubber article comprising a component composed of the rubber mixture.

A check joint structure for a connection of an air nozzle of a tire and a connection hose of an air compressor, the air compressor contains: a box, a sealant supply can, and a connection hose. The box includes a body of the air compressor. The sealant supply can includes an open segment and a supply tube. The connection hose includes a first segment and a second segment. The second segment has a check connector which includes a fitting sleeve, and the fitting sleeve has a threaded orifice, a through orifice, and a projected shoulder. A cylindrical base includes a cylindrical room, a stepped coupling segment, a conduit, and a first stepped portion. A first spring is received into the cylindrical room to abut against the first stepped portion. A valve bolt includes a contacting element, at least one cutout, a head, a conical rib, and a neck.

A tire repair device with an inflation compressor and a sealant material canister, and method of operation. A pressure gauge determines a tire inflation pressure, and a controller identities a completion of a sealant injection upon a pressure drop measured at the pressure gauge. The controller is configured to automatically shut off the inflation compressor when a tire pressure meets a predetermined inflation value after the pressure drop.

This invention reveals an uncured pneumatic tire which is comprised of a generally toroidal-shaped supporting carcass with an outer circumferential tread, two spaced beads, at least one ply extending from bead to bead, sidewalls extending radially from and connecting said tread to said beads, a sealant layer which is disposed inwardly from the supporting carcass, and an innerliner which is disposed inwardly from the sealant layer, wherein said circumferential tread is adapted to be ground-contacting, and wherein the sealant layer is comprised of polyisobutylene or a butyl rubber, wherein the polyisobutylene or the butyl rubber has a number average molecular weight which is within the range of 30,000 to 100,000.

Tires having a magnetic tire sealing material containing magnetic particles are described for detecting the presence of one or more sealed punctures in the tire. The tires can have a sealed tire portion that is formed by the magnetic tire sealing material flowing into and filling a puncture in the tire. The sealed tire portion includes a portion having magnetic particles and the portion being at the outer surface of the tire such as in the tread area. The tire can be positioned within the detection zone of an apparatus capable of detecting magnetic particles to indicate whether the tire contains a sealed puncture filled with the magnetic tire sealing material.

A bicycle tool according to the disclosure comprises a valve connection means. A tool element is connected with the valve connection means. The tool element is connected with the valve connection means in its longitudinal direction such that an elongated bicycle tool is formed.
