  • Patent number: 6067928
    Abstract: A filament guide assembly is provided with a support rod carrying a plurality of filament guides each for guiding a respective one of a plurality of filaments. A pair of support blocks mount the support rod at each end thereof to allow for (i) rotational movements between a raised position, wherein the filament guides are spaced from a respective one of the filaments, and a lowered position wherein the guides are in contact with the respective one of the filaments, and (ii) lateral shifting movements between an operative position, wherein the guides are aligned with the respective one of the filaments, and a rest position wherein the guides are laterally misaligned with the respective one of the filaments. Most preferably, the guide assembly is employed in combination with a finish oil applicator so that the guides bias the individual filaments into contact with finish oil nozzles thereof, and in so doing, ensure that positive contact between the finish oil nozzles and the filaments occurs.

  • Patent number: 5763003
    Abstract: A method and apparatus for covering a ribbon of optical fibers with a resin. The resin is polymerizable under the effect of UV radiation and forms a protective covering surrounding and holding the fibers. The method includes a pre-polymerization step during which the coated fibers advance through a UV irradiating chamber having a pre-polymerization ultraviolet radiation power of less than one fourth of the total power required to polymerize the resin, which is just sufficient to initiation polymerization. This step is followed by a polymerization finishing step during which the pre-polymerized ribbon is subjected to UV radiation of higher power than the radiation produced during the pre-polymerization step, which completes the polymerization process.

  • Patent number: 5709910
    Abstract: A system for applying textile treatment compositions to textile materials. A conduit member is provided which includes a passageway having a first end, a second end, and a medial portion with a constricted (narrowed) region. The passageway may include at least one baffle having an opening therethrough. A yarn strand is then moved through the passageway. A textile treatment composition (a sizing agent or dye) dissolved in a carrier medium (a supercritical fluid or liquified gas) is thereafter introduced into the constricted region, preferably at an acute angle relative to the passageway. The carrier medium expands inside the passageway which causes delivery of the treatment composition to the yarn. The treated yarn then passes through the baffle (if used) which facilitates drying of the yarn. During this process, a carrier gas can be introduced into the passageway to ensure the production of a smooth, dry product.

  • Patent number: 5639307
    Abstract: A fiber bundle workpiece is coated with a particulate material during passage about a plurality of pulleys arranged to establish a serpentine travel path portion through a coating zone. The pulleys have arcuate grooves extending thereabout, which cause the fiber bundle to twist axially, and the fibers of the bundle move with respect to one another as the fiber bundle moves along the serpentine path. These two actions increase coating efficiency and the penetration of particulate material into the fiber bundle. The travel path portion will preferably lie in a horizontal plane, and the coating unit will normally constitute an electrostatic fluidized bed of particulate material. After exiting the coating zone, the fiber bundle may pass through an oven to partially melt the particulate material, and thereby cause the particles to adhesively attach to the fiber bundle.

  • Patent number: 4467001
    Abstract: Apparatus and a process for coating continuous lengths of filaments are described. The apparatus includes a tubular vessel for applying a fluid coating to a plurality of traveling filaments which are then separated and passed through drying and curing zones in separate and appropriate ovens. The method of the invention, carried out in the apparatus of the invention, is particularly useful to apply special coatings to continuous lengths of hollow fibers to prepare composite hollow fibers useful as separatory membranes.

  • Patent number: 4419157
    Abstract: A process and apparatus for filling multi-conductor cables, particularly a telecommunication cable with several insulated wires surrounded by a covering and a sheath, with a mixture of powders which expand with the absorption of moisture. The conductors are fed in spaced relation into the entrance of a casing having an interior, frusto-conical wall which decreases in diameter from its entrance to its exit. The exit is small in diameter compared to the entrance so that the conductors converge as they pass from the entrance to the exit. Intermediate the entrance and the exit, the conductors are subjected to the powders which are caused to follow a helicoidal course by a screw which directs them toward the exit. Due to the shape of the casing wall, the powders are forced toward the conductors.

  • Patent number: 4411710
    Abstract: A method is disclosed in which an insulating film of an oxide of metal, of which a stranded conductor (30) is made, is formed on the surface of all strands in a stranded conductor, while the stranded conductor is held in the stranded form. In a step of oxidation-treating the strands of an electric cable the pressure of an oxidation treatment solution at the outer portion of the stranded conductor immersed therein is made higher than the pressure in the inner portion of the stranded conductor (30), causing the oxidation treatment solution (48) to be adequately penetrated from the outer portion into the inner portion of the stranded conductor to permit a desired oxide film to be formed on the surface of all the strands in the stranded conductor.

  • Patent number: 4325322
    Abstract: A liquid receptacle in the form of a chamber has a slit in one section thereof, the elongated sides of the slit being parallel straight lines. The chamber communicates through another section thereof with means for the supply thereto of a liquid treating composition at a controlled rate. Guide means configures a traveling multi-filament textile yarn in a close-packed monofilamentary layer and directs the so-configured traveling textile yarn under a desired tension and at a right angle over the slit and in contact with the chamber at a point downstream of the slit and in proximity thereto. The minimum length of the slit is equal to the total width of the traveling textile yarn when configured in a close-packed monofilamentary layer; and the width of the slit is between about 0.001 and 0.01 inches.

  • Patent number: 4273597
    Abstract: The conductors of a cable core unit are powder filled by passing the core unit through a fluidized bed of powder with the conductors substantially closed together. The filled cable core unit can be wrapped with tape after exit from the fluidized bed. Cable cores may be filled also by passing them through a fluidized bed. The core units of the cores may be closed together or separated, but the conductors of each unit are closed together.

  • Patent number: 4269023
    Abstract: For powder filling of cables, in a fluidized powder bed, it has been proposed to pass the cable core through the bed in a substantially closed condition. There is a limit to the number of conductors a core can have for effective filling. In the present invention the cable core is opened up into a number of core units by passing through an opening member. The opening member is freely ridable on the cable core and has a hole for each unit. The opener is held against a support member and an air bearing formed between the two members. Air is also usually fed to the holes in the opener member through which the core units pass to prevent flow of powder out from the bed. The opening member can be positioned in the fluidized bed or outside immediately prior to passage of the cable core through the bed. The units are each in a substantially closed condition in the bed and the units close to a single core also in the bed.
