Patent number: 11880061Abstract: A system for producing a multicore optical fiber includes a source of electromagnetic radiation in a spectral range that is suitable for inducing photopolymerization of a transparent polymer. An arrangement of one or more optical components is configured to concurrently focus the radiation that is emitted by the source on a plurality of elongated regions of the transparent polymer so as to photopolymerize the transparent polymer solely in the elongated regions to increase the index of refraction of the elongated regions such that in the optical fiber that is formed of the transparent polymer after the elongated regions are photopolymerized, each of the elongated regions functions as a core of the optical fiber and regions of the transparent polymer that surround the elongated regions function as a cladding of each of the cores.Type: GrantFiled: October 16, 2021Date of Patent: January 23, 2024Assignee: ZSQUARE LTD.Inventors: Zeev Zalevsky, Asaf Shahmoon, Amihai Meiri, Oran Herman

Patent number: 9920471Abstract: A rain-test resistant, high-vapor-permeable, water-repellent and water-resistant manufacturing process for making such fabrics is provided. It is used in the dyeing and finishing process of fabric in which the fabric is treated with the treatment roller, knife roller, and spray methods. These combined methods can coat water-repellent agent on the fabric and form a very thin film on the fabric. This protective film on the fabric enhances the wash resistance of the fabric while it will not adversely affect the water repellence and water resistance of the fabric. Moreover, this technique of forming a very thin water-repellent film on the fabric rules out the conventional method with which the water-repellent agent dipped within the fabric structure is easily washed out with regular laundry of the fabric due to the lesser amount of the agent being attached onto the fabric.Type: GrantFiled: July 15, 2016Date of Patent: March 20, 2018Assignee: G-Fun Industrial CorporationInventors: Qiu-Xiong Cai, Feng-Ying Tian, Jia-Yong Xie

Patent number: 7803431Abstract: A method for coating yarn is proposed, including steps in which the yarn is first placed in contact with a dispersion of the coating agent in a dispersing agent or with the coating agent in melted form, optionally excess dispersion or melt is scraped back off the yarn, and then the coating is formed on the yarn, where in the case of the dispersion this occurs by means of at least partially removing the dispersing agent by heating, and the yarn thus coated is then cooled down and wound, which is distinguished by the fact that the coated yarn undergoes additional cooling before winding.Type: GrantFiled: March 12, 2005Date of Patent: September 28, 2010Assignee: DSM IP Assets B.V.Inventors: Freddy M. J. Tijink, Henricus H. W. Feijen, Ronald Stiefelhagen, Christian Vieth, Johannes P. M. Dortmans

Publication number: 20100183821Abstract: A UVLED apparatus and method provide efficient curing of an optical-fiber coating onto a drawn glass fiber. The apparatus and method employ one or more UVLEDs that emit electromagnetic radiation into a curing space. An incompletely cured optical-fiber coating, which is formed upon a glass fiber, absorbs emitted and reflected electromagnetic radiation to effect improved curing.Type: ApplicationFiled: December 30, 2009Publication date: July 22, 2010Applicant: DRAKA COMTEQ, B.V.Inventors: Johannes Antoon Hartsuiker, Bob J. Overton, Xavier Meersseman

Patent number: 7750060Abstract: The invention relates to a radiation curable composition including a polyester urethane (meth)acrylate oligomer prepared from ortho-carboxylic polyester polyols, where the composition, after cure, has a secant modulus greater than about 600 MPa and an elongation at break of at least about 10%. The invention also relates to coated optical fibers and optical fiber ribbon including at least one coating derived from this composition, and to a process of making these coated optical fibers.Type: GrantFiled: October 17, 2005Date of Patent: July 6, 2010Assignee: DSM IP Assets B.V.Inventors: Edward P. Zahora, Anthony J. Tortorello, Edward J. Murphy, Anthony F. Toussaint, Timothy P. Reichert, Kelly A. Hawkinson

Publication number: 20100158469Abstract: The invention relates to coated optical fibers comprising soft primary coatings and to such primary coatings for protecting glass optical fibers having a sufficient high resistance against cavitation. In particular, the primary coatings have a cavitation strength at which a tenth cavitation appears (?10cav) of at least about 1.0 MPa as measured at a deformation rate of 0.20% min?1 and of at least about 1.4 times their storage modulus at 23° C. The coating preferably shows strain hardening in a relative Mooney plot, preferably has a strain energy release rate Go of about 20 J/m2 or more, and preferably has a low volumetric thermal expansion coefficient. The invention furthermore provides a method and apparatus for measuring the cavitation strength of a primary coating.Type: ApplicationFiled: November 13, 2009Publication date: June 24, 2010Applicant: DSM IP ASSETS B.V.Inventors: Markus J.

Publication number: 20100092689Abstract: A long-lasting water-repellency textile application that uses a polydimethylsiloxane (PDMS)-containing polyurethane (PU) involves a manufacturing process of NCO-terminated PU prepolymer of PDMS diols and polyisocyanate with a catalyst for forming a moisture-curable PDMS-containing PU oligomer, or becoming an UV-curable PDMS-containing PU oligomer after a chemical reaction takes place. The PU oligomer owns PDMS moiety with water-repellent properties. The moisture- or UV-curable PU with NCO and acrylate end-groups can create cross-linked polymeric networks between fibers of textiles by exposing to the air or UV-radiation. The final cross-linked PDMS-containing PU treated textile demonstrates long-lasting water-repellent properties with an excellent soft hand feel and a breathable feature. Furthermore, the textile water-repellent treatment is cost-effective, and most importantly these two different curing processes could be carried out at ambient temperature without requiring any waste water discharge.Type: ApplicationFiled: July 19, 2009Publication date: April 15, 2010Inventors: Wei-hung CHEN, Po-cheng Chen, Shih-chieh Wang, Kan-nan Chen
