Abstract: A reinforced "C" shaped hand-rail for use with escalators, moving pavements and the likes made of elastic material. The invented hand-rail is injection moulded from polyurethane, foamed polyurethane or other synthetic material possessing similar physical characteristics, so that at least one of its outside and inside is lamellated, the external or internal surface of the side opposite the lamellated surface is wavy conforming to the lamellae. The hand-rail is provided with reinforcing steel wire insert (1).

Abstract: The invention relates to an apparatus for the comminution of organic matters, the comminuting unit of which consists of at least one tool provided with axial and/or radial yielding holes and co-acting axially driven stamp. The essential feature of the invention is that a compacting unit (4) before the comminuting unit (5)--in respect of the direction of movement of the organic matter to be comminuted--and a feeding-precompacting unit (3) preceding the compacting unit (4) are arranged, furthermore the feeding-precompacting unit (3) is provided with driven worms (6, 7, 8), the discharge end of which is connected with the large cross sectional end of the bell-mouthed narrowing chambers (18, 19) while its reduced cross sectional end is joined to the pressure chamber (28) of the tools (20, 21).

Abstract: The invention relates to an elastic self-carrying bellows-body, in particular for vehicles, having been formed with ribs separated by spacings and interconnected with connecting means.The essence of the invention lies in that the thickness of the connecting means interconnecting the ribs is less on at least two opposite sides of the bellows-body, than that of the ribs and the ribs and connecting means are formed as monolithic units.

Abstract: This invention relates to a process and equipment for the crushing of scrap rubber, particularly scrap tire. According to the invention the scrap rubber is forced through small-size openings under a pressure producing the cold yield of the rubber.

Abstract: A coupling for reinforced hoses comprises inner and outer metal sleeves with the end of the reinforcement secured between them. The hose core and cover of elastomeric material are disposed respectively on the inner and outer sides of the reinforcement and are bonded thereto and underlie at least a portion of the inner and outer metal sleeves, respectively. The bore of the coupling is smooth and may be comprised entirely by the hose core or by a smoothly continuous inner surface of the hose core and the inner sleeve.
