Abstract: An improved method for producing impregnated reinforcing threads is disclosed. The method involves impregnating glass, carbon or aramid fibers with a twist ≦120 turns/m with a polymer dip, drawing the impregnated threads through a nozzle, drying the threads superficially in a first heating zone where they are kept moist in the core, and then providing them with a twist up to 400 turns/m in a second heating zone in which they are heated to fix this twist. The fibers are intimately impregnated with polymer, so that the impregnated threads have high fatigue strength, and a compact, constant cross section throughout their length. The impregnated threads are particularly suitable for reinforcing driving belts and high pressure hoses; they can be made into wovens and scrims which, in turn, can be used for reinforcing tires, conveyor belts and the like.

Abstract: A pre-twisted cable pair and a method for processing such pairs into an electrical cable having improved electrical and mechanical properties is disclosed. At least one insulated wire for transmitting electrical signals is pre-twisted prior to pairing with another insulated wire.

Abstract: A bitumen-based waterproofing membrane is provided with an improved edge for sealing with a contiguous membrane to provide a membrane system with improved waterproofing characteristics. A bitumen-based reinforced membrane sheet is coated with granular material to protect the membrane sheet from ultraviolet rays. However, a section of the membrane sheet is first covered with a piece of protective tape which prevents any granular material from being deposited on the lateral section of exposed bitumen beneath the tape. The membrane sheets are then cut immediately prior to the tape or at the edge of the granular coating and then rolled up. Accordingly, the lateral section of bitumen which is covered by the protective tape is on the innermost part of the rolled-up membrane sheet. During installation, the tape is removed and the exposed bitumen or selvage section is disposed below an adjacent or contiguous membrane. Heat is then applied for an easy and effective seal between two adjacent membrane sheets.

A crack or hole in either an inside or outside surface which extends at least to the encapsulated filament bundle interiors will alert the tank's operator/owner to a leakage problem.

Abstract: Applicants have discovered that the speed of fiber manufacture can be substantially increased by employing a two-step curing process in which the fiber is drawn, coated and exposed to ultraviolet light on-line at high line speeds to effect a partial cure of the coating. After further cooling, the partially cured coating is fully cured by an on-reel exposure to ultraviolet light. The on-reel exposure can take place on the draw tower take-up reel as it is filing with fiber or it can take place off-line after the take-up reel has been filled and removed from the line. The on-reel exposure advantageously takes place either during filling the take-up reel, or during emptying the reel, so that each layer of fiber on the reel is exposed equally to the ultraviolet light. This method of UV illumination improves the energy efficiency in the second exposure by at least a factor of 10 to as much as a factor of 1000. The fiber primary coating pullout strength and mechanical modulus are enhanced.

A sensor feedback loop can dynamically adjust the reel-out drag force to dampen vibration modes during reel out which can cause tangle.
