    Abstract: Concrete strengthening members, particularly prestressing tendons such as strands of steel wire, are provided with a strongly adherent plastic coating which may be substantially impermeable for improved corrosion resistance, and/or which may have embedded therein abrasive or grit-form particles to provide improved bond with the concrete, and particularly to provide controllable bond transfer in prestressing tendons of the pre-tensioned type. The plastic coating preferably is applied electrostatically in powder form, and fusion bonded by heat. The abrasive can be applied by spraying during a viscous state of the heated resin, and can be varied as to size and spacing density so as to control the surface condition and the bonding effect. Fusion and curing heat may come from preheating of the member before application of the resin powder, which preferably is a heat curable, thermosetting epoxy. Coating thickness and grit application are readily variable to meet particular requirements. Particularly advantageous results are achievable for high strength steel strands for prestressing concrete by pretensioning, facilitating their use where previously considered impractical or impossible.

    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: A corrosion resistant PC steel stranded cable for a pretensioning method has a core wire and a plurality of side which are coated firmly for the corrosion proof with paint of a synthetic resin material while maintaining a stabilized stranded condition. The cable comprises the single core wire and the plurality of side wires disposed in a closely contacting relationship with each other and also with the core wire in such a manner as to define a plurality of spiral air gaps between the core wire and the side wires and also to define a plurality of spiral recessed grooves between individual adjacent ones of the side wires on the outer side of the side wires. Each of the core wire and the side wires are processed by blueing in advance. Paint of a synthetic resin material is filled in the spiral air gaps, and a coating layer of paint of a synthetic resin material is formed substantially with a uniform thickness on an entire outer periphery of the side wires including the spiral recessed grooves. A process of and an apparatus for producing such corrosion resistant PC steel stranded cable are also provided.

    Abstract: The present invention relates to a method of continuously impregnating and encapsulating a wire rope with a liquid polymer formed from at least two reactive components which when mixed and heated together react chemically to form the polymer. In accordance with a preferred embodiment of the invention, the components are separately pumped into a mixer and then into an injection die, and a preheated wire rope is passed through the injection die. The wire rope is preheated to a temperature sufficient to initiate reaction of the components. The reaction of the components forms the liquid polymer which continuously flows into the voids or spaces of the wire rope and encapsulates the outer surface of the wire rope. The liquid polymer cures in and around the wire rope to form a unitary impregnated and encapsulated wire rope.

    Abstract: The cable includes continuous glass filaments which are helically plied in rovings at a constant helical angle from cable center to outer surface and bonded together in elastomeric material. When heated, thermal elongation of the filaments is opposed by simultaneous radially directed thermal volumetric expansion of the elastomeric material. Thus, with respect to overall cable length, thermal elongation of the cable is opposed by a simultaneous increase in cable cross sectional area such that thermal elongation effects are controllable, dependent upon the thermal expansion properties of the filament and elastomeric materials used, by controlling the helical angle at which the filaments are plied to obtain either expanding, contracting or constant length cables, as desired. Thermal contraction effects produced by cooling the cable also are controllable by controlling the helical angle. In some high tensile load cable applications, the helical angle additionally may be related to tensile load, depending upon the modulus of elasticity of the filaments used. The invention is particularly adapted to helically plied glass fiber cables which are thermally stable over a wide range of temperatures.
