Abstract: The invention relates to a flexible floor for an intercommunication bellows between two cars which, while they are traveling in a straight line, move in a longitudinal direction, said floor presenting transverse undulations enabling it to follow the relative displacements of said cars as they are going around bends, while also enabling passengers to go between the cars by walking on the top face of the floor, said transverse undulations being reinforced by metal blades extending in a transverse direction of the floor, and said floor being provided with an elastomer reinforcement interposed between the blades of each pair of said metal blades.

Abstract: The invention relates to a flexible floor designed to be suspended from an undulating flexible bellows in order to form a corridor connection module, said floor presenting undulating raised edges at its transverse ends, and, on its bottom face, transverse ribs in which metal reinforcements are embedded. According to the invention, at least some of the metal reinforcements have ends that project beyond the transverse ribs, each of which projecting ends is coupled to a fastening device for fastening the floor to the bellows, which fastening device extends alongside the outside of the corresponding undulating raised edge and presents a fastening end for fastening to the bellows that is situated above the corresponding raised edge.

Abstract: Method of manufacturing a cylindrical type frequency adapter including at least one assembly in the form of an elastomer ring molded between and adhering to an inner armature and a cylindrical ring wherein the assembly or each of the assemblies is sleeved into an outer sheath. After the elastomer ring is molded between the inner armature and the cylindrical ring and the resulting assembly is cooled, without carrying out any diameter reducing operations, the assembly is sleeved into the outer sheath after which the diameter of the complete adapter is reduced by plastic deformation of the outer sheath which also reduces the diameter of the cylindrical ring.
