Abstract: In a handrail including a carcass, a stretch inhibitor within the carcass, and a sliding layer bonded to the carcass, at least a portion of the carcass has a gas phase dispersed in a solid polymer matrix. The gas phase can reduce a density of the carcass by at least 5% or 10%, or about 15%, as compared to a density of the polymer matrix. The carcass can have a generally uniform distribution of gas bubbles in the polymer matrix, which can define a generally closed cell structure in the polymer matrix. The gas phase can be formed of particles of a syntactic foam dispersed in the polymer matrix. The handrail can further include a cover. The carcass and the cover can be formed of thermoplastic materials, and the cover can represent between 10 and 30% of the overall TPU required for the handrail.

Abstract: The present invention relates to a motor comprising at least one piston of linear and reciprocating translational movement and a swash plate mounted at an angle on a shaft driven in rotation in an engine block by the reciprocating movements of the plate which is in contact with the piston. Each piston is integral with a rod, the end of which opposite the piston includes a slide which moves in a guide in the engine block. Each slide holds two shells which form a seat for each swivel joint of the swash plate. Preferably, the swash plate includes two or four swivel joints.
