A cable including a conductive composite core formed from braided carbonized fibers and fiberglass fibers. At least a portion of the fiberglass fibers are coated with magnetic material to suppress electromagnetic interference noise. Methods of forming such cables is also provided herein.

An assembly and process for forming a two stage extruded pipe having a central inner sleeve and a pair of outer attached lobes. The central sleeve shaped (also termed a grout receiving tube) is produced in an initial extrusion operation, following which it enters a cross head operation where a pair of outer lobes are attached to cross sectional exterior surface locations according to a second stage extrusion operation so as to be integrally formed therewith. Other steps include cooling of the dual stage extruded pipe, as well as sectioning and stacking the pipe. Additional steps include forming elongated slots or apertures into the central sleeve portion of the finished extrusion, such in non-interfering fashion with the individual passageway defining and lobes.

Embodiments of the disclosure relate to an optical fiber subunit. The optical fiber subunit includes a buffer tube having an interior surface and an exterior surface in which the interior surface defines a channel. The optical fiber subunit also includes a first lumen disposed within the channel. The first lumen includes a first membrane having a thickness of 0.15 mm or less and surrounds a first plurality of optical fibers. A second plurality of optical fibers disposed within the channel and outside the first lumen. Also disclosed are embodiments of an optical fiber cable having one or more lumens disposed within a central bore of a cable jacket and embodiments of a method of manufacturing an optical fiber cable.

This invention relates to a medical tube comprises an elongate conduit having a first opening, a second opening, a longitudinal axis, a lumen extending between the first opening and the second opening along the longitudinal axis, and a corrugated wall, formed from an extruded material, extending between the first opening and the second opening and surrounding the lumen. The wall is stiffer in a first length of the conduit adjacent the first opening than in a second length of the conduit adjacent the second opening. The variable stiffness of the tube wall can improve the thermal profile of the tube as well as improve drain-back of condensation into a humidifier providing humidified gas to the tube.

A method for manufacturing a lightweight cowl crossbar includes: producing an inner pipe, laminating a plurality of composite material layers wound around the inner pipe, and extruding an outer pipe on the winding layer, in which the plurality of composite material layers adjacent to each other are wound in different directions.

The present invention relates to an elastic pull rope used in exercise, comprising an inner tube layer with a hollow channel, a woven wire layer surrounding the outer part of the inner tube layer and an outer tube layer surrounding the outer part of the woven wire layer, wherein the woven wire layer surrounds the outer surface of the inner tube layer via a plurality of first wire rods, and weaving a plurality of second wire rods around the first wire rods in an overlapping manner in order to form and clamp the woven wire layer between the inner and outer tube layers, so that the formed elastic pull rope would have improved overall structural strength.

A wear-heat-resistant anti-bacterial anti-fouling steel wire framed pipe and a manufacturing method thereof are provided. The steel wire framed pipe includes: an anti-bacterial anti-fouling inner layer, an enhancement layer and a wear-heat-resistant outer layer from inside to outside in turn, wherein: the anti-bacterial anti-fouling inner layer is made from antifouling and antibacterial composite modified polyethylene; the wear-heat-resistant outer layer is made from wear-resistant cross-linked modified PE-RT; the enhancement layer includes an interlayer and two steel wire gauze layers respectively coating on an inner surface and an outer surface of the interlayer, and the interlayer is respectively bonded with the anti-bacterial anti-fouling inner layer and the wear-heat-resistant outer layer via hot-melt adhesive. The steel wire framed pipe provided by the present invention has high structural strength, wear-resistance, heat-resistance, and anti-bacterial and anti-fouling properties.
