Resulting fibers were tens of micrometers in diameter depending on the inner diameter of the capillary tip. AFM image verified that molecular long axis of the virus fibers were parallel to the fiber long axis. Although aqueous M13 virus suspension could not be spun by electrospinning, M13 viruses suspended in 1,1,1,3,3,3-hexafluoro-2-propanol were spun into fibers. After blending with highly water soluble polymer, polyvinyl 2-pyrolidone (PVP), M13 viruses was spun into continuous uniform virus blended PVP (virus-PVP) fibers.

    Abstract: A method and apparatus for determining and adjusting binder laylength during the process of manufacturing a selected fiber optic cable design. Specifically, a binder, having a distinguishing and physically detectable feature, is wrapped around fiber optic bundles or a buffer tube. A detection system detects the unique feature associated with the binder and thus creates a calculates a representative distance value. The distance value is calculated in relation the periodic spacing between two detected points on the physically detectable binder and is continuously monitored by a closed feedback loop. A computer receives status data from the closed feedback loop and compares the received data to a stored laylength parameter. In light of the comparison, an algorithm adjusts the binder head speed accordingly. This process repeats until the desired stored laylength is detected by the detection system.

The apparatus comprises a first plurality of stationary payoff reels each wound with a length of bare wire conductor. The conductors are simultaneously payed off the reels to a pay out accumulator for accumulating a portion of the conductors during replacement of spent pay out reels. At least one extrusion process arranged downstream of the accumulator applies a plastic insulation material to a respective conductor as it passes through its respective extrusion process. A cooling and/or curing trough through which water is flowed cools and/or cures the plastic insulation. A take-up accumulator arranged downstream of the cooling and/or curing trough accumulates a portion of each insulated conductor during changeover of the take-up reel arranged downstream of the take-up accumulator.

  • Patent number: 6385956
    Abstract: A packing yarn and a method of manufacturing a packing yarn composed of at least two bands which are at most 5 mm wide and are joined together by a yarn manufacturing method, include forming the bands of a laminate having at least one layer of flexible graphite and at least one layer of a metal foil with a tensile strength of at least 250 MPa. The layers of graphite foil and metal foil are joined by adhesion or through the use of a non-adhesive-like coupling agent. The bands are produced from the laminates by cutting, which is preferably effected continuously. Advantages thereof are that strips or bands of flexible graphite, which have a tensile strength that is totally inadequate for the manufacture of packing yarns, are altered in terms of their mechanical properties.

  • Patent number: 6238605
    Abstract: The invention relates to a process for the production of a low-fibrillation moulded body containing polytetrafluorethylene. The process is characterised in that a pre-moulded body of polytetrafluorethylene is twisted and then pressed flat. The pre-moulded body can be twisted around itself or around another material e.g. a mono- or multifilament or a spun yarn. The invention relates furthermore to a low fibrillation moulded body containing polytetrafluorethylene which can be obtained by means of the process in accordance with the invention and the use of the moulded body in accordance with the invention as dental floss.

  • Patent number: 6109015
    Abstract: In a method of producing poly(trimethylene terephthalate) yarn from PTT chip which has been extruded through a spinneret into filaments and coated, the coated filaments are passed between an unheated feed roll and a tension roll to tension them without causing permanent stretching, and then are passed from the tension roll to a heated draw roll to draw the filaments in a single draw step to a draw ratio of 1.25 to 4.0 and to heat them to a temperature between their glass transition temperature and their crystallization temperature.

  • Patent number: 6101804
    Abstract: A method of and an apparatus for making twisted electrical cable, such as 600 volt secondary distribution (UD) cable, and the twisted cable product are disclosed. The apparatus comprises a first plurality of stationary payoff reels each wound with a length of stranded bare wire conductor. The stranded conductors are simultaneously payed off the reels to a pay out accumulator for accumulating a portion of the stranded conductors during replacement of spent pay out reels. An extruder apparatus arranged downstream of the accumulator applies a plastic insulation material to a respective stranded conductor as it passes through the extruder. A cooling trough through which water is flowed cools the plastic insulation. A take-up accumulator arranged downstream of the cooling trough accumulates a portion of each insulated conductor during changeover of the take-up arranged downstream of the take-up accumulator.

  • Patent number: 6083556
    Abstract: A thread conditioner to prevent fraying, tangling and associated problems is made from silicone rubber material, such as a silicone elastomer having a physical form of rubber-crepe. The material can be cut from a bulk quantity, rolled, cut into cubes, pressed, and packaged. The conditioner is applied to one end of a length of thread by pressing the thread into the material and pulling the thread across the material, with enough pressure to embed the thread into the material as it is pulled through so that the thread is coated on all surfaces with the material.

  • Patent number: 5983618
    Abstract: Apparatus and systems for applying filling compound, such as water blocking compound, and water absorbing powder to a core wire or wires of a stranded conductor or to subsequent layers of a stranded conductor, which are particularly suitable for use with a tubular strander, include a rotatable head, which may be positioned downstream of a wire strander. The core is drawn through a core passage where the filling compound is applied to the core and powder is applied to the filling compound. Strand through passages are provided through the rotatable head, for drawing the strand wires therethrough, without being coated. The strand wires are stranded about the core in a closing die. Preferably, the powder circulation circuit is a closed circuit, enabling recycling of the powder. The powder is preferably fluidized prior to its delivery to the applicator, and is withdrawn from the applicator under a slight vacuum.

  • Patent number: 5829242
    Abstract: The modulus of stretch af a fibrous rope is reduced by impregnating a pluity of spaced-apart segments of the rope with an epoxy plastic thereby to reduce the modulus of stretch of the segment equal to zero after curing the plastic. The overall modulus of stretch of a re-manufactured rope taken as a whole is proportional to the ratio of the length of an impregnated segment relative to a unit length of the rope.

  • Patent number: 5688301
    Abstract: An irregularly shaped glass fiber is provided which enjoys improved resiliency, and openness in pack structures. Wool packs and other wool portions having such irregularly shaped fibers may be processed directly through needling to form a non-woven material without intervening steps such as carding or blending of fibers which accompany conventional glass fiber processing operations. In a further aspect of the invention, a non-woven material including irregularly shaped fibers in a generally continuous wool tow is produced by "unwinding" a fiberglass wool pack collected by a direct forming method. Product applications include simplified, lower cost processing, and new uses of the irregularly shaped fibers produced by rotary fiberization in filtration elements, sorbants, gaskets, packings, shingles, composite structural elements, furnishings, textiles, yarns, and blown-in insulation systems.

  • Patent number: 5683642
    Abstract: A PC strand is formed by twisting peripheral wires made of deformed PC steel wires around a core, and allowing rust inhibitive material of thermoplastic resin to permeate into voids defined among the core and peripheral wires by use of an extruder. Since at least one of the core and peripheral wires is made of a deformed PC steel wire having an uneven outer surface, the thermoplastic resin can smoothly permeate deep into the inside of the PC strand.
