Patent number: 6132650Abstract: A base polymer is mixed with a non-polymerizable compound having a higher refractive index to form a fiber material. This material is continuously transformed into a fiber in a fiber-preparing unit. The fiber is dipped in diffusion tanks containing monomer substances so as to diffuse these substances into the fiber, and cured in a heater so as to polymerize these substances. By alternatingly repeating this procedure, the monomer substances and the non-polymerizable compound are diffused in the fiber and form a graded refractive index. Next, the fiber is drawn, coated with a cladding and coiled. This method can be performed with a high running ratio, minimizing the necessity of scaling-up of the facilities when the production is increased, and easily confers a desired index grading on the fiber. Likewise, the method allow continued manufacturing of a graded refractive index plastic optical-fiber with a desired length and of constant quality.Type: GrantFiled: March 6, 1998Date of Patent: October 17, 2000Assignee: Sumitomo Wiring Systems, Ltd.Inventor: Tetsuya Nakamura

The spinning conditions are chosen such that the monomers are substantially contained within the fiber during extrusion and curing and the total of the spinning masses is intrinsically thread forming. The spinning masses may be extruded in, e.g., water. The core and the sheath polymer may be, e.g., poly(methyl methacrylate); the core monomer may be methyl methacrylate, and the sheath monomer may be 2,2,3,3-tetrafluoropropyl methacrylate; or the core and the sheath polymer may be, e.g.Type: GrantFiled: May 13, 1998Date of Patent: August 22, 2000Assignee: Akzo Nobel NVInventors: Bastiaan Krins, Richard Hendrikus Gerrit Brinkhuis

Patent number: 6108475Abstract: A fiber optic cable having stress indicating means and a method for making same. The stress indicating means provides a cost effective method for determining whether an optical cable has been bent, stressed or otherwise mishandled, which may cause optical loss when the cable is placed in service. Broadly stated, the fiber optic cable according to the instant invention includes an optical fiber, comprised of a core and a cladding and a stress indicator concentrically disposed about the fiber that changes color when subjected to stress. A technician can thereby visually identify cables that have been bent or mishandled and subject them to testing before installation.Type: GrantFiled: December 22, 1997Date of Patent: August 22, 2000Assignee: Lucent Technologies Inc.Inventors: John T.

Patent number: 6091878Abstract: An improved optical light pipe for side-lit uses is formed from a core/cladding combination, optionally with a transparent jacket, where the core is preferably a cured acrylic polymer and the cladding is preferably a fluorocarbon polymer containing a very low level of fine particles which scatter the light uniformly along the length of the piping. Further light enhancement can be obtained with low levels of glass fibers or glass microspheres also present in the cladding. Chopped glass fibers alone at low levels in the cladding are useful for back-lit applications. The light pipe so formed is useful in signs, underwater outlines, corridor lighting in theaters, and similar uses.Type: GrantFiled: November 20, 1997Date of Patent: July 18, 2000Assignee: Rohm and Haas CompanyInventors: Mark Allan Abramowicz, Jeffrey Lawrence Daecher, Michael Paul Hallden-Abberton

Patent number: 6083342Abstract: A system and method for rapidly labeling a blow-molded hollow container made of a plastic composition subject to out-gassing after de-molding. Otherwise, conventional high speed silk screen labeling technology and processing is employed shortly after container fabrication de-molding in order to accurately deposit a continuous liquid layer of conventional silk screen ink over an external container surface area designated for application thereon of a self-adhering pre-printed label. The label is rapidly and accurately transfer applied over the silk screen coated area immediately after the same has dried, and even while out-gassing is still occurring from the de-molded to container. However, the protective ink barrier coating prevents formation of bubbles beneath the label. Those gases in the container wall resident beneath the label-affixed area can then nevertheless out-gas by migrating out of the container internal wall surface.Type: GrantFiled: March 18, 1998Date of Patent: July 4, 2000Assignee: Owens-Brockway Plastic Products Inc.Inventor: Eugene J.

Patent number: 6077468Abstract: A low melting, high solids spin finish composition is provided that can be readily applied to synthetic fibers during the fiber-making process. The spin finish solids, which make up at least about 70% by weight of the spin finish composition, comprise nonionic hydrocarbon surfactant components, such as polyoxyalkylenes, which have a <HLB> value of from about 2 to 13 and a melting point within the range of about 25.degree. C. to about 140.degree. C. In some embodiments, the spin finish composition also includes select fluorochemicals.Type: GrantFiled: January 11, 1999Date of Patent: June 20, 2000Assignee: 3M Innovative Properties CompanyInventors: Chetan P.

Patent number: 6074578Abstract: The invention comprises a plasticating machine for the working and forcing of plastic material into a mold, the machine including an elongated barrel housing having a first or proximal end and a second or distal end, and an elongated screw shaft with a screw flight therearound, the screw shaft being rotatably supported in the elongated barrel housing, for the working of plastic between the screw shaft and the elongated housing. At least one delivery conduit is generally longitudinally arranged within the wall of the housing. The delivery conduit with the housing wall may be arranged to heat or cool the screw and any plastic being worked therethrough. In a further embodiment, it may permit delivery of a medium within the wall, from an upstream location of the housing, into the primary flow path of any plastic being driven from the machine and into a mold.Type: GrantFiled: December 30, 1996Date of Patent: June 13, 2000Inventors: Desider G. Csongor, Donald N. Halgren

Patent number: 6068796Abstract: A simplex optical fiber cable of this invention includes an optical fiber, a buffer preferably of nylon, surrounding and in contact with the optical fiber, a yarn layer with strength fibers, preferably aramid fibers, disposed about the buffer and a sheath preferably formed of polyvinyl chloride (PVC) surrounding and in contact with the yarn layer. In cross-section, the simplex optical fiber cable has a diameter less than 2.0 millimeters (mm), and thus is much smaller in diameter than optical fiber cables presently available. Preferably, if the buffer is relatively tin providing limited protection to the optical fiber, a slick substance such as talc is applied to an outer surface of the buffer before the yam layer is disposed thereon. The slick substance allows the buffer of the optical fiber to slide to a degree in contact with the yarn layer and thus reduces fatigue caused by axial movement of a ferrule of the connector terminating the optical fiber cable.Type: GrantFiled: December 10, 1998Date of Patent: May 30, 2000Assignee: Lucent Technologies Inc.Inventors: Lionell Graham, James Robert Holman, Terry Don Mathis, Montri Viriyayuthakorn

Patent number: 6066275Abstract: A method and apparatus for determining and controlling the excess length of a communications element disposed in a conduit is disclosed. The method includes the steps of measuring the length of a communications element being disposed within the conduit, placing a mark on the conduit each time a pre-determined length of the communications element is disposed within the conduit, and measuring the distance between the marks on the conduit. The excess length is determined by comparing the distance between the initial mark and the subsequent mark on the conduit to the measured length of the communications element disposed within the conduit. To control the excess length ratio, the conduit may be stretched, or process parameters related to formation of the conduit may be changed.Type: GrantFiled: July 7, 1998Date of Patent: May 23, 2000Assignee: AlcatelInventors: Richard T.
