Abstract: A composite multi-layer textile, comprising at least one nanofibre layer with nanofibres with diameters below 100 nm and one support layer with microfibres with diameters below three microns, wherein the layers were produced by electrospinning. The multi-layer textile shows a general transmittance at #=550 nm greater than 60%, which shows improved properties concerning transparency, breathability and robustness. This is achieved in that the at least one nanofibre layer and the support layer are fused, forming solid domains in the multi-layer textile, at closed areas of a pattern used in the production process, wherein the solid domains are separated from each other or connected, showing defined shapes, with regular or irregular spatial distribution, while the fibre morphology of nanofibres of the nanofibre layer and microfibres of support layer is preserved on top of the open areas beside the solid domains, attaining a general transmittance greater than that given by the sum of the individual layers.

Abstract: The present invention relates to a tyre for vehicle wheels comprising at least one structural element comprising a crosslinked elastomeric material obtained by crosslinking a crosslinkable elastomeric composition comprising a predispersion of natural rubber and lignin obtained by co-precipitation from latex, where said lignin has a concentration of phenolic groups higher than 2 mmol per gram of lignin, and where said predispersion comprises an amount of said lignin such as to provide, in said crosslinkable elastomeric composition, a concentration of lignin equal to or lower than about 25 phr.

Abstract: A motorcycle including a frame to which an internal combustion engine is associated, from which internal combustion engine at least one exhaust pipe of combusted gases departs, the exhaust pipe having an open terminal, the frame mounted on a front wheel and a rear wheel, a control board or unit included, for controlling torque produced by the engine and other parameters such as velocity of the vehicle and spatial position thereof with respect to the road surface. The motorcycle including a system to verify when the front wheel of the motorcycle detaches from the road surface during acceleration. The system includes a choke for partializing the section of the exhaust gases outlet area from the exhaust pipe, during partialization. The partialization obtained as a function of the torque produced by the engine and the position of the front wheel with respect to the road surface.
