Abstract:
Bei diesem Kunstfaserseil mit mehrlagig verseilten tragenden Aramidfaserlitzen (9, 10, 11), wird vorgeschlagen, dass anstelle einer bisher extrudierten, schützenden Kunststoffummantelung nur eine zusätzliche Beschichtung (10) der Kunstfaserlitzen (4,5) der äussersten Litzenlage (6) mit Imprägniermittel und Zusätzen von UV-Stabilisatoren, Kurzfasern, Oxidations- und Reduktionsblockern aufgebracht wird und dadurch ein zuverlässiger Schutz gegen das Seil schädigende Umwelteinflüsse sowie eine ausreichende Abriebfestigkeit des Kunstfaserseils (1) unverändert sichergestellt sind.
Abstract:
PROBLEM TO BE SOLVED: To provide a simulator that is quiet and short enough to be built in high density shopping and entertainment venues while remaining efficient enough to allow commercially viable operation.SOLUTION: A vertical wind tunnel flight simulator comprises a flight chamber wherein a flier experiences a freefall simulation. Airflow to support the flier is induced by fans connected above the flight chamber through a duct. A staging area having openings to the flight chamber is adjacent to the flight chamber. One or two return air ducts are used to return air from the fans to the fans inlet. Opposed louvers are included on at least one duct segment thereby regulating the temperature via forcing ambient air into the simulator. The use of many duct segments having diverging walls adds commercial value to the system by lowering the height. Mounting components on a roof and behind walls creates a spectacular pedestrian viewing scene of people in flight.
Abstract:
The invention relates to a method for producing a wire cable (1), wherein a core strand (3) is compacted and then braid strands (2) are stranded on the core strand (3), characterized in that the core strand (3) is hammered before stranding of the braid strands (2) in order to smooth the surface (10) thereof. A plastic layer is advantageously applied to the core strand (3) before stranding of the braid strands (2), wherein the braid strands (2) are pressed into the plastic layer (7), preferably while the plastic layer (7) is heated. In the preferred embodiment of the invention, the core strand is a core cable (3) and the braid strands are strands (2) of the wire cable (1) or the core strand is a heart strand (3) and the braid strands are outer core strands of a core cable of the wire cable. A greater breaking strength of the wire cable (1) is obtained by hammering the core strand (3) in order to smooth it than by compacting a core strand (1) with a roller compressor. The invention further relates to the wire cable (1) and to a device for producing the wire cable (1).
Abstract:
Hybrid rope (20) comprising a core element (22) containing high modulus fibers surrounded by at least one outer layer (24) containing wirelike metallic members (26). The core element (22) is coated (23) with a thermoplastic polyurethane or a copolyester elastomer, preferably the copolyester elastomer containing soft blocks in the range of 10 to 70 wt %. The coated material (23) on the inner core element (22) is inhibited to be pressed out in-between the wirelike members (26) of the hybrid rope (20) and the hybrid rope (20) has decreased elongation and diameter reduction after being in use.
