A rope comprises a core extending along a longitudinal axis and a sheath surrounding the core, the sheath extending along the longitudinal axis. A strap at least partially surrounds the sheath, the strap being separated from the core by the sheath. At least one thread passes several times through the strap, sheath and core to form several links fixedly securing the strap on the core and sheath. The links pass through a central section of the core, the central section corresponding to a circular section representing less than 50% of the cross-section of the core. The links are angularly offset from one another when observed along the longitudinal axis.

A belt for suspending and/or driving an elevator system component include one or more metallic cord tension elements extending along a length of the belt, and one or more non-metallic tension elements extending along a length of the belt. Each non-metallic tension element is formed from a non-metallic material. The one or more metallic cord tension elements and the one or more non-metallic tension elements are arrayed laterally across a lateral width of the belt. The belt may be used in an elevator system including a hoistway, a drive machine having a traction sheave coupled thereto, an elevator car movable within the hoistway. The belt is operably connected to the elevator car and interactive with the traction sheave to suspend and/or drive the elevator car along the hoistway.

A cord (50) comprises a single layer (52) made up of N helically wound metal filamentary elements (54) having an outer diameter D, the metal filamentary elements (54) defining an internal enclosure (58) of the cord of diameter Dv. Each metal filamentary element (54) has a diameter Df and a helix radius of curvature Rf. With this cord (50), D, Dv, Df and Rf being expressed in millimeters: 0.10≤Jr≤0.25, 9≤Rf/Df≤30, and 1.60≤Dv/Df≤3.20, where Jr=N/(π*(D−Df))×(Dh×Sin(π/N)−(Df/Cos(αx π/180))) and α is the helix angle, expressed in degrees, of each metal filamentary element (54).

The present invention relates to an eco-friendly tire cord and a tire using the eco-friendly tire cord, in which use of a recycled polyethylene terephthalate (PET) fiber reduces environmental load and also provides physical properties equivalent to or better than those of a tire cord that is produced by application of a virgin PET fiber and particularly, excellent heat resistance equivalent to or better than that of a tire cord produced by application of a virgin PET.

Example embodiments provide a reinforced fairing apparatus and method for hydrodynamic drag and vibration reduction. Example embodiments provide a reinforced fairing apparatus comprising a tow cable, a plurality of ribbons, and a plurality of stiffening elements. According to example embodiments, the tow cable may comprise strands of a metal arranged into at least one line and configured to be attached at each end. The plurality of ribbons may extend from at least part of the tow cable. Each ribbon may have at least one of the stiffening elements in a configuration throughout the length of the ribbon. The plurality of ribbons, aided by the stiffening elements, may be configured to be pliable during storage and streamlined with fluid flow during use. The plurality of stiffening elements may be a plurality of midribs.
