Abstract: An elevator in which the sheave diameter is reduced and the attendant lowering of the rope life and strength is suppressed to secure safety and reliability. To this end, a rope is used in which a plurality of element wires constituting the wire rope are each covered with resin material and the whole wire rope is covered with resin material, thereby reducing the wear due to slippage between the element wires and the wear due to contact with the sheave, which wear occurs when the rope is entrained around the sheave. When the elevator sheave diameter is reduced, a worried lowering of the rope life can be suppressed or the rope life can be improved. Thus, it is possible to achieve reduction of size and weight of equipment including motors and hoists, installation space saving for elevators, improved safety and reliability of the system by virtue of the increased rope life.

Abstract: Processes for coating sewing thread using a radiation curable composition and the resultant coated sewing thread. Sewing thread is coated with a radiation curable composition, which exhibits a self sustaining cure after exposure to radiation.

Abstract: A marking yarn for selective use in formation of a textile fabric, such as a tubular pantyhose blank, comprises an elongate strand-like yarn base formed of a water-soluble material and at least partially coated with a material which is detectible by an ultraviolet sensor. When the marking yarn is included in the textile fabric, e.g., by knitting one or more courses of the marking yarn in plated relation with the body yarn of the hosiery blank, the yarn effectively designates a predetermined location in the fabric of the hosiery blank which can be subsequently detected by an ultraviolet sensor in the sewing of the hosiery blank into a pantyhose garment. In subsequent wet processing of the garment, e.g., dyeing, the marking yarn dissolves, thereby removing it from the fabric and liberating the coating material.
