    Abstract: Elevator, preferably an elevator without machine room. In the elevator, a hoisting machine engages a set of hoisting ropes by means of a traction sheave. The set of hoisting ropes comprises hoisting ropes of substantially circular cross-section. The hoisting ropes support a counterweight and an elevator car moving on their respective tracks. The hoisting rope has a thickness below 8 mm and/or the diameter of the traction sheave is smaller than 320 mm. The contact angle between the hoisting rope or hoisting ropes and the traction sheave is larger than 180°.

    Abstract: A tire cord having core filaments preformed into a helical configuration while maintaining the core filaments in a parallel, side-by-side relationship. The core filaments are not twisted or stranded together. High tensile strength sheath filaments are also preformed into a flattened helical configuration so that the sheath filaments can be wrapped around the side-by-side core filaments such that the sheath filaments do not put such tension on the core filaments as to cause the core filaments to bunch. The core filaments are maintained in a flat, side-by-side configation so that no voids are formed and rubber can penetrate into the tire cord. The core filaments may number from three to six and the sheath filaments from one to seven. The cross-section of the tire cord is flattened and confined within an oval-shaped outer bound, the oval outer bound being characterized by a major axis and a minor axis. It is desirable that the minor axis be no greater than 60% of the major axis to created the appropriate difference in the bending modulus of the tire cord in the horizontal versus the vertical direction.

    Abstract: The invention relates to a reinforcing cable for a flexible endless caterpillar track made of an elastomer. The cable (30) comprises a plurality of strands (32C, 32P) each formed from steel filaments and arranged so as to be wound in a helix in the thickness of the belt. Each strand comprises a core composed of at least three filaments (34), an intermediate layer composed of a plurality of filaments (36) and surrounding the core, and an outer layer composed of a plurality of filaments (38) surrounding the intermediate layer. Application to caterpillar tracks for all-terrain vehicles.

    Abstract: A steel cord comprising a core and a sheath arranged around the core. The core consists of two steel filaments, and the sheath consists of eight steel filaments. The diameter of each of the filaments is in a range from 0.30 to 0.42 mm, and a difference D.sub.c -D.sub.s between the diameter D.sub.c of the filaments of the core and that D.sub.s of the sheath is not less than 0.04 mm. The twisted direction of the core is the same as that of the sheath, and a ratio P.sub.s /P.sub.c between a pitch P.sub.s of the sheath and that of P.sub.c of the core is in a range from 1.4 to 3.0.
