Abstract: Method for vulcanizing a tire by predetermining a degree of vulcanization, comprising the steps of determining specified structural and dimensional parameters of the tire and of a vulcanization mould, determining the change over a time (t) of specified thermodynamic parameters of the tire, of the mould, of heat-supply fluids and of a cooling fluid, determining a parameter consisting of an equivalent vulcanization time t0, and determining an equivalent degree of vulcanization X(t0) at specified points within the tire by means of an equivalent isothermal rheometric curve at a reference temperature T0, comprising three consecutive sections having the following equations: X ⁡ ( t o ) = { k ⁢   ⁢ t o

Abstract: An emergency device is provided to enable a number of people to be transferred between two areas far apart from each other. The device includes a flat relatively stiff plate capable of being rolled up upon itself and susceptible of longitudinal and transverse deformations according to curvilinear profiles, and plate-deforming elements to change the plate from a flat configuration to an operational one including successive transversely oriented hollow portions. The deformation elements can be a waterproof fabric layer joined to the plate sides and provided with tubular ducts extending over the entire length of the plate. Under operating conditions, the plate is unrolled and the tubular ducts are inflated with pressurized fluid to deform the plate according to the successive hollow portions. The upper layer of the fabric can form an emergency slipway for a plurality of people and the lower hollow-shaped plate can provide a slipway for moving articles.

Abstract: The sealing strip includes a first structural member for anchoring the strip to the edge of an opening, such as a door or a trunk or the like, of a motor vehicle body, a second deformable structural member for providing sealing along the edge of the door or the like closing the opening in the vehicle body and a continuous rib interconnecting the first and second structural members. The rib has dimensions and/or geometrical configuration and/or physical properties which vary along a longitudinal axis of the strip.
