Abstract:
A rope (3) is described for a tropospheric aeolian generator (1) composed, in length, of at least one first sector (4) adapted to resist to repeated flexure cycles, having a safety coefficient (S1), a diameter D(b1) and an aerodynamic resistance coefficient (CD1); at least one second sector (5) adapted to resist to repeated traction cycles with great load, having a safety coefficient S2
Abstract:
A synthetic fiber rope having an armor cover layer (3) formed of flexible synthetic resin to cover the outer peripheries of a plurality of strands (2) of synthetic fiber constituting the outer peripheral side of the synthetic fiber rope. And the position of the cab in the elevator shaft is pre-set by one colored region of the armor cover layer (3) lengthwise of the synthetic fiber rope, on the basis of the relationship between the colored region and the sheave having the main rope entrained therearound, so as to provide the synthetic fiber rope with a position index function. This makes the index to be easily identified even after the long-term use of the elevator, excluding defective conditions caused by the index becoming unidentifiable due to wear with time or the like. Therefore, it is possible to properly cope with operations for rescuing passengers from the cab during accidental stoppage and to speed up rescue operations.
Abstract:
Non-metallic rigging chain (6) is formed with a plurality of linked flexible loops (7). Each loop (7) has a core (22) which consists of a continuous strand (24) of non-metallic materially coiled upon itself. The coiled core material is sheathed within a woven outer fabric (26). Except for the two material loops of each chain, one loop (7) is formed by coiling a continuous strand (24) of core material in linked relation within a pair of completed loops (7). The length of each chain is determined by the diameter of its loops and the number of loops linked together. One end of the strand (24) is fixed to a pin (50) on a link of a metal chain (34) driven around two spaced sprockets (30,32) interlinked with the pair of completed loops (7). Each metal link of the driven chain (34) has a pin (50) to define the position of the strand (24) as it is unwound from a supply spool (52).
Abstract:
A stent is provided with braided filaments. First and second filaments (12, 14) are braided with each other and extend spirally around the stent wall in opposite directions. One or more third filaments (16) are braided with the first filaments (12) and extends spirally around the stent wall only in the direction of the second filaments (14). The third filament (16) is stiffer than the first and second filaments (12, 14), and there are fewer third filaments (16) than the first and second filaments (12, 14).
Abstract:
There is disclosed a method of forming an eye end termination on a rope having a core comprising a plurality of multi-strand subropes, and a rope having a core comprising a plurality of multi-strand subropes and at least one eye end termination. In one embodiment, a method of forming an eye end termination (16) on a rope (10) having a core (12) is disclosed. The rope comprises a plurality of multi-strand subropes (14) each of a first strength, and the method comprising the steps of: coupling a pair of subropes ( 14) in the rope core ( 12) together using a multi-strand coupling rope ( 18) of a second strength which is greater than said first strength, to thereby form at least part of the eye end termination (16). The step of coupling the pair of subropes (14) together comprises splicing a first portion of a coupling rope (18) to one of the subropes in the pair of subropes, and splicing a second portion of the coupling rope to the other one of the subropes in the pair of subropes.
Abstract:
A suspension and transmission device for use with an elevator system comprises one or more strips that provide load carrying, transmission or traction, and load carrying redundancy or safety functions for the elevator system. In one version a single strip comprised of polymer and composite materials provides these functions. In another version multiple strips comprised of polymer and composite materials provide these functions. In another version, a strip comprises a hollow interior portion. In another version one or more strips incorporate materials that can be detected when using the strip to monitor the condition of the one or more strips.
