A method for producing a tire filled with a (meth)acrylic hydrogel, the method comprises a) providing a mixture comprising at least one water-soluble (meth)acrylic compound, water and an initiator, and b) filling the mixture in a tire in which the mixture polymerizes to form the (meth)acrylic hydrogel. The tire filling material is suitable for producing flat proof tires, enables fast and controlled cure and is insensitive towards dosage errors. Moreover, the tire filling material is environmental friendly and cost effective.

A puncture repair liquid holding container is formed from: a container main body provided with a holding portion and an opening portion; and a cap attached to the opening portion, including a second flow channel for the cap to discharge the puncture repair liquid inside the container, wherein a tube extending toward an inner side of the container main body is attached to the second flow channel, the tube is provided with a sealing film that blocks inflow of the puncture repair liquid to the second flow channel, and a closed condition where the sealing film blocks the second flow channel can be switched to an opened condition where the sealing film is broken by container internal pressure such that the second flow channel is opened.

The applicator repair system includes a repair device including a repair element configured to repair a damaged applicator element on an applicator of an AM system. The damaged applicator element is configured to distribute a layer of raw material on a build platform of the AM system. The repair device is positioned within a processing chamber of the AM system. A damaged applicator controller may be provided that is configured to cause repair of the damaged active applicator in response to the damaged applicator being identified as damaged.

A portable glass repair kit system and method, more particularly, for windshield repair for laminated glass and the like to provide an easy to use, highly portable, and economical glass repair kit. The glass repair kit does not require specialized equipment such as an injector, plugger device, suction cups, or require any additional tools or specialized knowledge of how to use the repair kit. The glass repair kit contains a resin which may be urged by a user through slight pressure after the glass repair kit is adhered over an impact point and any cracks thereby repairing a windshield in a more cost effective, time efficient, and user friendly way.

This invention is based upon the unexpected finding that the reaction product of polyisobutylene and a silane can be incorporated into tire sealant formulations to greatly reduce the level of hysteresis exhibited by such sealant formulations which decreases the rolling resistance of the tire to improve fuel economy. This is made possible by the further unexpected fining that silanes will react with polyisobutylene by a reaction which is initiated with a peroxide. This invention more specifically discloses a sealant composition which is particularly useful in manufacturing self-sealing tires and which is comprised of (a) the reaction product of polyisobutylene and a silane; and (b) a reinforcing filler. The sealant compositions also contain a peroxide to facilitate partial degradation of the polyisobutylene rubber during the curing of the tire.

A method for dispensing temperature-automotive body sealant includes providing a dispensing system having a pump operable to pump the sealant and a manifold receiving the sealant and operable to temperature-adjust the sealant has an elongated central body and elongated passages extending from the first end to the second end. First and second end caps are detachably connected to ends of the central body. A thermal unit is in thermal communication with the elongated central body and operable to heat or cool the elongated central body. A dispenser is in fluid communication with the manifold and operable to dispense the temperature-adjusted sealant. Sealant is pumped through the manifold and heated or cooled so as to provide a temperature-adjusted sealant. The temperature-adjusted sealant is dispensed from the dispenser.

A puncture repair liquid injection method injects puncture repair liquid into a tire by using a puncture repair liquid injection device provided with a container having a liquid containing portion containing a puncture repair liquid, along with an outlet for discharging the puncture repair liquid, and an inlet for introducing compressed air; an injection hose connected between a tire valve of a wheel mounted on a tire and the outlet of the container; and a compressor having a pressure adjuster for selecting an air pressure. The method further comprises connecting the injection hose between the tire valve and the outlet of the container, connecting the compressor to the inlet of the container, selecting a reduced air pressure as a pressurizing force by the compressor by an operation of the pressure adjuster, and injecting the puncture repair liquid into the tire by pressurizing the container interior.

A method for the weight-dependent control of the internal pressure of a supporting body loaded by a weight load or payload, wherein the internal pressure is produced by means of an electric-motor-driven compressor, and the weight load or payload which is present and which acts on a supporting body in the form of a mass m.sub.Load under the effect of acceleration due to gravity g is determined in that a reduction and a subsequent increase in the internal pressure take place, wherein the increase in the internal pressure causes the position of an application point of the weight load or payload to change by a position difference Z, wherein:

during the increasing of the internal pressure by means of the compressor, the motor current I.sub.Load of the drive motor of the compressor is measured with a constant motor voltage U and integrated over the time of the increase in pressure, and the electrical work W.sub.Load which is necessary for the change in position is determined therefrom,

wherein the electrical work W.sub.Load the electrical work W.sub.Load is compared with a characteristic value of the electrical work W.sub.0 from a characteristic diagram, wherein the change in position Z, the difference in mass m and the difference in payload F.sub.Z are determined from the difference W between W.sub.Load and W.sub.0 and the mass m.sub.Load and the weight load or payload which is actually present as a result is determined therefrom.

The invention relates to a pneumatic vehicle tire with a material ring (10) inside it, adhesively attached to the inner surface opposite from the tread (1), the material ring (10) adhering to a self-sealing sealant (8), which at least immediately after its application has a tackiness required for the adhesive attachment of the material ring (10). To improve the sealing effect, the material ring (10) arranged on the sealant (8) is closed-cell and airtight.
