Patent number: 10436985Abstract: The invention relates to a method for producing an optical waveguide (1), the surface of which is at least partly coated with a coating material. The coating material contained in a target (4) is removed using laser radiation (6) of a processing laser or converted into another aggregate state. The coating material is then deposited on the surface of the waveguide (1) and forms a coating thereon, said coating modifying the light guidance. It is the object of the present invention to provide an improved method for producing optical waveguides, in which guidance of undesired electromagnetic radiation and/or guidance of radiation in undesired areas of the waveguide is avoided. To this effect, the present invention proposes that the laser radiation (7) reflected from the target (4) or transmitted through the target heats-up the waveguide (1), said laser radiation (6) being polarized and impinging the target (4) at a specified angle (?) between 10° and 80° relative to the surface normal.Type: GrantFiled: December 21, 2012Date of Patent: October 8, 2019Assignee: FRAUNHOFER-GESELLSCHAFT ZUR FORDERUNG DER ANGEWANDTEN FORSCHUNG E.V.Inventors: Steffen Bohme, Thomas Schreiber, Gerd Harnisch

Patent number: 10220594Abstract: Hydrophobic thermal insulation fiberglass flexible blanket using a textile grade fiberglass is produced by impregnating a hydrophobic polymer (e.g. a fluoropolymer) dispersion into a fiberglass blanket/mat, such as a needle felted fiberglass (FG) blanket/mat. The preferred FG needle felt blanket is a mechanically, rather than organically, bound glass fiber insulating blanket. The hydrophobic polymer dispersion forms a hydrophobic coating on the surface of the fiberglass filaments. Integral hydrophobicity is achieved and maintained without the need to add commonly-used hydrophobic inorganic particles, such as treated silica aerogels or fumed silica. Optionally, to enhance overall hydrophobicity and to inhibit fibrous surface lofting, a super-hydrophobic coating of fluoropolymer and inorganic particles such as silica particles may be dispersed onto one or more surfaces of the blanket.Type: GrantFiled: July 19, 2017Date of Patent: March 5, 2019Inventors: Lewis Dill, Chengjun Zhou
