Abstract:
The invention relates to a heavy-duty roundsling, which comprises an endless load-bearing core containing multiple turns of a strand material comprising high-performance fibres, and a protective cover made from interlaced strands comprising high-performance fibres, and wherein the mass ratio of high-performance fibres in the core to high-performance fibres in the cover is from 0.15 to 2.0. Said roundsling shows an advantageous combination of properties, like high strength, low weight, and high durability; enabling a higher number of lifting operations than known metal or synthetic slings, especially of heavy goods with e.g. sharp edges.
Abstract:
A metal cord (100) comprising at least two metal strands (101 A-G). At least one strand (lO1D) is welded, said welded strand having an elongation at rupture of more than 30% of the elongation at rupture of an identical strand without weld.
Abstract:
PROBLEM TO BE SOLVED: To provide a coated wire rope for operation, which has improved adhesiveness of a resin coating layer. SOLUTION: The coated wire rope for operation has a resin coating layer 5 on the outer circumference of a core wire rope 4 obtained by twisting a plurality of side strands 2, 3 around a core strand 1, wherein the side strands 2, 3 are composed of multiple kinds of strands having different strand diameters D 2 , D 3 .

Abstract:
Câblé textile à haut module (50) à au moins triple torsion (Tl, T2, T3), comportant au moins N brins (20a, 20b, 20c, 20d), N étant supérieur à 1, retordus ensemble selon une torsion finale T3 et une direction finale D2, chaque brin étant constitué de M pré-brins (10a, 10b, 10c), M étant supérieur à 1, eux-mêmes tordus ensemble selon une torsion intermédiaire T2 (T2a, T2b, T2c, T2d) et une direction intermédiaire Dl opposée à D2, chaque pré-brin consistant lui-même en un filé (5) qui a été tordu préalablement sur lui-même selon une torsion initiale Tl (Tla, Tlb, Tic) et la direction Dl, dans lequel au moins la moitié des N fois M filés présente un module initial en extension noté Mi qui est supérieur à 2000 cN/tex. Ce câblé textile est avantageusement utilisable comme renfort dans les pneumatiques pour véhicules, en particulier dans la ceinture ou dans l'armature de carcasse de ces pneumatiques.
Abstract:
A hybrid rope (40) or a hybrid strand (50) comprising a core element (42, 52), a first (44, 54) and a second (46, 56) metallic closed layer surrounding said core element (42, 52). The core element (42, 52) includes a bundle of synthetic yarns. The first metallic closed layer (44, 54) includes a plurality of first strands of wires helically twisted together with the core element (42, 52) in a first direction. The second metallic closed layer (46, 56) includes a plurality of second wires or strands helically twisted together with said core element (42, 52) and said first metallic closed layer (44, 54) in a second direction. The cross-sectional area of the core element (42, 52) is larger than the total cross-sectional area of the first (44, 54) and second (46, 56) metallic closed layers. A corresponding method of producing such a hybrid rope or hybrid strand is also disclosed.
Abstract:
The object of the invention is a method and an apparatus for lubricating a rope laid from wires in the manufacturing phase of the rope. By means of the invention lubricant, e.g. lubricant (5) containing solid substances such as grease, a grease compound or a paste, is spread onto at least one wire (1) of each strand of the rope to be laid. The lubricant (5) to be spread onto the wire (1) is dispensed onto the endless surface (10) moving in a different direction with respect to the direction of movement of the wire (1) and is conveyed on the aforementioned endless surface (10) into contact with the wire (1).
Abstract:
A vertical wind tunnel flight simulator comprises a flight chamber wherein a flier may experience 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 outlet 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 the roof and behind walls creates a spectacular pedestrian viewing scene of people in flight.
