Abstract:
The invention concerns a method which consists in forming subassemblies (6) by assembling pultruded strands (5) consisting of traction resistant fibres embedded in a resin, and coating the assembled strands in a protective plastic jacket (7). Said subassemblies are wound on transport reels (12). On a manufacturing site preferably located on the sea front, the tether (4) is formed by assembling the subassemblies unwound from the transport reels, and by coating the assembled subassemblies in an outer plastic sheath (9). The resulting tethers can then be transported to the platform for anchoring the latter.
Abstract:
A tension member (22) for an elevator system (12) has an aspect ratio of greater than one, where aspect ratio is defined as the ratio of tension member width w to thickness t (w/t). The increase in aspect ratio results in a reduction in the maximum rope pressure and an increased flexibility as compared to conventional elevator ropes. As a result, smaller sheaves may be used with this type of tension member (22). In a particular embodiment, the tension member includes a plurality of individual load carrying ropes (26), formed from metallic material encased within a common layer of coating. The coating layer (28) separates the individual ropes (26) and defines an engagement surface for engaging a traction sheave (24).
Abstract:
An elevator system having multiple machines and flat ropes is disclosed. In one embodiment, the machines are engaged in a series manner with a single set of ropes to drive the car and counterweight. In another embodiment, each machine is engaged with a separate set of ropes to drive the car and counterweight.
Abstract:
An elevator system having a compact machineroom is disclosed. The elevator system uses a traction machine engaged with flat ropes to minimize the size of the machine. As a result, the machineroom is very compact and may be installed vertically adjacent to the hoistway without exceeding the roof line of a building. In another embodiment, the machineroom is a self-contained unit that may be pre-assembled and shipped to the building site to minimize installation time and costs.
Abstract:
Werkstoff auf der Basis faserverstärkter Materialien, wie kohlefaserverstärkten Kunststoffen, Prepregs, Towpregs, mit einer mindestens bereichsweise vorhandenen polymeren Hülle, wobei die Hülle einen Härtegradienten aufweist, nämlich von härter zu weicher von innen bis zur Oberfläche der Hülle.
Abstract:
A security device has a flexible strap (26) with a lock unit (28) attached at each end. The strap (26) comprises a plurality of longitudinally extending multi-filament cables or ropes (2) arranged in a substantially planar array embedded in an elastomeric material (4). The cables or ropes (2) have a coating of primer for creating a bond with the elastomeric material (4). The primer may be restricted to the external surface of the cables or ropes (2), or some of the surfaces of the filaments may be free of primer. This facilitates relative movement of the filaments during flexure or compression of the strap (26). Moreover, an extrusion process for manufacturing the strap (26) including a priming station (12) is disclosed.
Abstract:
The present invention relates to a retroreflective, elongated, filamentous product, comprising a core of non-metallic filamentous material; a first polymer matrix layer comprising a polymer resin, located around an outer peripheral surface of, and penetrating into, the core of non/metallic filamentous material; a reflective material located on an outer peripheral surface of said first polymer matrix layer; a second polymer matrix layer comprising a polymer resin, forming a primer layer on top of said reflective material; and a plurality of refractive microparticles distributed in said second polymer matrix primer layer, wherein said plurality of refractive microparticles is partially embedded in said second polymer matrix primer layer. A process for making the product and uses thereof are also disclosed.
Abstract:
An elevator rope (100) comprises a steel cord (114) and an elastomer jacket (140) surrounding the steel cord. One or more yarns (120, 122) are wrapped or braided or knitted around the steel cord before the elastomer jacket is applied. The yarns are therefore integrated into the polymer jacket. The yarns induce a pattern at the surface of the polymer jacket. By amending the yarn structure, the surface pattern of the polymer jacket can be changed. This has an implication on the friction of the elevator rope on the sheave on which it is running. Furthermore, the integrated yarns help to preserve the integrity of the elastomer jacket. In a second aspect of the invention a method is claimed wherein first one or more yarns are wrapped, braided or knitted around the steel cord prior to extrusion of the elastomer. The yarn mantle ensures a good centricity of the elastomer jacket and an improved processability of the elevator rope.
