Inflatable article equipped with a layer impermeable to the inflation gases, of improved hysteresis and impermeability. The layer comprises an elastomer composition comprising at least, as the sole elastomer or as the predominant elastomer by weight, a thermoplastic styrene elastomer (TPS) and a platy filler having a volume content greater than 5%. According to one preferred embodiment, the TPS elastomer is a copolymer with polystyrene and polyisobutylene blocks such as SIBS (styrene/isobutylene/styrene) and the composition also comprises an extender oil for the elastomer, in particular a PIB (polyisobutylene) oil. The platy filler is especially chosen from graphites and phyllosilicates such as micas, clays or talcs. The inflatable article can be an inner tube or a pneumatic tire for a motor vehicle.

Provided is a pneumatic tire in which a sealant layer entirely exhibits sufficient sealing performance. The present invention relates to a pneumatic tire including a sealant layer located radially inside an innerliner, the sealant layer being formed by continuously and spirally applying a generally string-shaped sealant to the inner periphery of a tire in the tire width direction from one side to the other, the attachment start portion of the sealant being located tire-widthwise inward from the tire-widthwise end of the sealant layer.

Provided is a self-sealing tire that is excellent in the effect of reducing adhesion of foreign materials to the sealant layer, sealing performance, and road noise-reducing properties while maintaining the balance between them. The present invention relates to a pneumatic tire, including: a sealant layer located radially inside an innerliner; and a sound-absorbing layer located radially inside the sealant layer, the sound-absorbing layer being formed by applying a porous sound-absorbing material to the inner periphery of the sealant layer.

Provided is a pneumatic tire including: a sealant layer located radially inside an innerliner; and a sound-absorbing layer located radially inside the sealant layer, the sealant layer being formed of a generally string-shaped sealant provided continuously and spirally along the inner periphery of the tire, the sound-absorbing layer being attached with the sealant.

A crown reinforcement of a tyre includes at least one crown triangulation belt having a given width value (R). The belt essentially includes elementary widths each having a given width value (B). Each of the elementary widths has a flattened cross section and forms an angle () with a circumferential direction of the tyre, the angle () being between 10 and 80. Adjacent elementary widths, which are positioned directly next to each other, are separated by a groove of a given width value (j) and are connected to each other by one or more weak bridges.

Techniques for implementing mechanisms for chaining continuous queries are provided. In some examples, results of a first continuous query may be stored in a data object. For example, the first continuous query may be configured to process business event data and store the results in the data object. Additionally, a second continuous query may then be processed based at least in part on the results stored in the data object.

An apparatus for manufacturing a rubber member includes an extruder; a mouthpiece; and a support surface which faces the mouthpiece in an opposed manner. The apparatus further includes: a rubber pool portion formed between the mouthpiece and the support surface; and a closing surface having an inclined surface shape and capable of closing a moving-direction front side of the rubber pool portion. A rubber material is ejected from an ejection port in a state where the rubber pool portion is closed by the closing surface, the support surface and the mouthpiece are moved relative to each other after the rubber pool portion is filled with the rubber material, and a lamination starting end of the rubber material is pressed to the closing surface thus molding the lamination starting end into an inclined surface and, thereafter, the closing surface is moved in a direction away from the support surface.

The present invention relates to: a method for manufacturing a polymer film, the method including a base film forming step for co-extruding a first resin containing a polyamide-based resin and a second resin containing a copolymer including polyamide-based segments and polyether-based segments; a co-extruded film including a base film including a first resin layer containing a polyamide-based resin, and a second resin layer containing a copolymer having polyamide-based segments and polyether-based segments; to a co-extruded film including a base film including a first resin layer and a second resin layer, which have different melting points; and to a method for manufacturing a polymer film, the method including a base film forming step including a step of co-extruding a first resin and a second resin, which have different melting points.

Embodiments of the invention include a method of forming a pneumatic tire having a heat insulating layer and a pneumatic tire having a heat insulating layer, for reducing the thermal cooling of a tread of a pneumatic tire. A flexible heat insulating layer is applied to the tire at a location radially inward from the tire tread and opposite the tire tread relative the tire thickness. The heat insulating layer is characterized as having thermally insulating properties configured to maintain at least a portion of the tire tread at or above a desired elevated temperature greater than a glass transition temperature for any such portion of the tire tread under normal tire operating conditions. The heat insulating layer is also characterized as having a low thermal conductivity.

Techniques for counting event changes with archived relations are provided. In some examples, a query that identifies at least a data object may be identified. Additionally, the query may be evaluated against historical data associated with the data object. Additionally, in some instances, a listening service may be registered with the data object. Further, the query may be evaluated based at least in part on the data object and the historical data.
