    Abstract: A hoist rope for an elevator is formed from synthetic, non-metallic materials. The hoist rope includes a plurality of load-carrying strands with each strand encased within a coating layer. The coating layers provide protection against wear and provide sufficient lubricity to permit relative movement of the strands to equalize loading on the strands. The plurality of strands are surrounded by a jacket. The jacket provides sufficient traction with a traction sheave, transfers traction loads to the strands while permitting movement of the strands, and provides a flame retardant characteristic to the hoist rope. In one embodiment of an passenger conveyor system, the hoist rope is engaged with a traction sheave having a sheave liner. The material for the jacket and sheave liner are selected to optimize the coefficient of friction between the hoist rope and traction sheave.

    Abstract translation: 用于电梯的起重绳索由合成的非金属材料形成。 起重绳索包括多个承载绳股，每个绳索包裹在涂层内。 涂层提供防止磨损的保护，并提供足够的润滑性以允许股线的相对运动以均衡股线上的负荷。 多个股线被外套包围。 护套通过牵引滑轮提供足够的牵引力，将牵引载荷传递到绳索，同时允许绳索的移动，并为提升绳索提供阻燃特性。 在乘客输送机系统的一个实施例中，提升绳索与具有滑轮衬套的牵引滑轮接合。 选择护套和滑轮衬套的材料，以优化起重绳索和牵引滑轮之间的摩擦系数。

    Abstract: A tendon for use in posttensioning prestressed concrete comprising a multi-wire strand wherein individual peripheral abutting wires define an overall somewhat regular geometric cross-sectional strand configuration. The strand has both internal and external interstices wherein said external interstices are substantially fully filled with a dielectric plastic material such as a high molecular polyolefin material such as high density polyethylene. The plastic material forms a casement which completely surrounds the strand and forms a smooth outer surface having a circular cross-sectional configuration. A friction reducing grease-like material is coated on the outside of the casement and the entire structure thereafter enclosed in a plastic jacket. The above structure is formed by progressively extrusion coating the wire strand with the dielectric plastic, the thus coated strand with the grease-like material and the thus coated composite with plastic to form the jacket.

    Abstract: A flexible cable comprises a plurality of substantially parallel, textile core threads and an external sheath, in which cable cohesion is provided by a binder which is applied in a discontinuous manner to the threads to bond the core threads to one another to form a core. The same or additional binder is used to bond the core to the sheath. An electrical conductor element may be provided centrally of the core and the sheath preferably is braided in position about the core. In addition to the beneficial properties associated with totally impregnated cables, the cables of this invention possess a very high flexibility. These cables or ropes can be used for all applications in which flexibility and strength are the principally desired qualities including, for example, motorway crash barriers, oceanography, ballooning, and fixing floating stations in the sea.
