Abstract: Aspects of the invention relate to a tire that includes a shoulder wedge arranged in a shoulder portion of the tire between the sidewall and the belt package, the shoulder wedge being at least partially inserted between the belt package and the carcass ply. The tread includes a tread chimney component extending from the shoulder wedge to the rolling surface. The overlay coat of the tire's belt package, the tread band except for the tread chimney component, the tread base and the tire sidewall are made from non-conductive rubber. A conductive path between the rolling surface and the rim is provided across the tread chimney component, the shoulder wedge, the carcass ply and the chafer portion.

Abstract: A method of detecting a critical state of closing of a preform during a phase of closing of the preform following a phase of deposition of layers of material that reduce the radial size of an opening formed in the preform smaller in the radial direction comprises the steps of injecting a gas into the opening, measuring a pressure in a pipe element through which the injected gas flows and detecting the critical state of closing of the optical preform on the basis of a measured pressure.

Abstract: A method for treating humans or non-human animals for dysuria comprising administering an effective non-toxic amount of alfuzosine or a pharmaceutically acceptable salt thereof to a human or non-human animal suffering dysuria.
