  • Patent number: 6596786
    Abstract: There is provided a radiation-curable coating composition containing oligomers that each have two end groups X1 and X2, wherein the end groups X1 and X2, which may be the same or different, are a photoinitiator group or an adhesion promoter group. The coating composition may exclude the presence of non-reactive photoinitiator groups and non-reactive adhesion promoter groups, each of which would fail to covalently bond itself to an oligomer backbone.

  • Patent number: 6579914
    Abstract: A composition for coating an optical waveguide, more specifically, an optical fiber, and optical fibers coated therewith. The coating composition is a radiation curable composition including an aliphatic epoxide, a urethane acrylate oligomer, a reactive diluent, and cationic and free-radical photoinitiators. The cationic photoinitiator acts upon the aliphatic epoxide while the free-radial photoinitiator acts upon the urethane acrylate oligomer. The resulting cured coating forms an interpenetrated polymer network. The properties of coatings in accordance with the invention including the glass transition temperature thereof, can be tailored to achieve advantageous coatings suitable for use as primary coatings and secondary coatings for an optical fiber.

  • Patent number: 6321014
    Abstract: A method for manufacturing optical fiber ribbon containing optical fibers having colored layers. The color is provided in a secondary coating composition that is cured prior to application of a matrix material for forming the optical fiber ribbon. The secondary coating composition includes a photoinitiator that is relatively insensitive to oxygen, and the environment to which the secondary coating composition is exposed is limited by removing the boundary layer of air surrounding the secondary coating composition prior to the application of the matrix material thereto.

  • Patent number: 5262640
    Abstract: Mounting of a sensing unit upon the interior surface of a vehicle windshield for detecting the presence of moisture upon the exterior surface and controlling operation of windshield wipers in response thereto is disclosed. The sensing unit comprises a block in which angularly oriented bores are disposed. Light pipes in a first set of the bores communicate with light sources for transmitting light to the outer surface of the windshield, and light pipes in a second set of the bores transmit light reflected from the outer surface to photo-detectors. The lower ends of the light pipes are coplaner with or raised slightly above the surface of the block which is to be secured to the windshield. The block is affixed to the interior surface of the windshield by a double faced adhesive interlayer which both securely adheres the block to the windshield surface and optically couples the light pipes to the windshield.
