摘要： The invention relates to a buoyant flexible hose and method for making same wherein buoyancy is imparted to the hose by an annular sleeve which surrounds said hose and is constituted by an inner layer consisting of a series of axially successive preformed annular bodies of cellular high polymer which are surrounded by an outer layer of a wear resistant polymeric material with the interposition of an intermediate layer of a reinforcing fabric between said inner and outer layers. The outer layer is formed in situ and together with the intermediate layer constitutes a unitary body structure, which is continuous and uninterrupted in the entire extent along said axially successive annular bodies.

摘要： A molded upholstery article of expanded polyurethane is formed with an inner core and a preformed polyurethane skin in which the skin is microporous and intimately joined to the inner core. The skin has cells uniformly distributed in its thickness as a fine cellular structure, which cells are for the most part nonintercommunicating, and having a diameter smaller than 0.02 mm. The skin is waterproof and its density is between 0.4 and 0.8. The process for preparing said molded upholstery article involves coating the mold surface with a thin coat of a first liquid mixture of polyurethane forming substances, then pouring in the so-coated mold a second liquid mixture of polyurethane forming substances without waiting for the components of the first mixture to have completed their reaction. The formation of the expanded foam by its pressure and release of heat controls the final step of the formation of the microporous polyurethane skin and provides an intimate union with it. No heat is provided to the reaction and air at room temperature remains in direct contact with the mold walls.
