Coating continuous filaments

Coating continuous filaments. Albarino, Robert Vincent; Torza, Sergio (Bell Telephone Laboratories, Inc., USA). U.S. US 4073974 14 Feb 1978, 13 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: B05D001-18. NCL: 427163000. APPLICATION: US 75-600280 31 Jul 1975. DOCUMENT TYPE: Patent CA Section: 57 (Ceramics) Mech. distortions of optical glass fibers are prevented by coating the fibers with hexamethylcyclotrisilazane [1009-93-4] or octadecyltriethoxysilane [7399-00-0]. The fibers are passed through a fluid-filled container contg. upper and lower constrictive openings. A decreased pressure is maintained in the container to prevent flow of the coating from the container. The coatings are thermally cured.

Particles with their surfaces modified by hydrophilic and hydrophobic groups. Gruening, Burkhard; Holtschmidt, Ulrich; Koerner, Goetz; Rossmy, Gerd (Goldschmidt, Th., A.-G. , Fed. Rep. Ger.). Ger. Offen. DE 3411759 C1 25 Apr 1985, 13 pp. (German). (Germany). CODEN: GWXXBX. CLASS: ICM: C09K003-00. ICS: B01F017-00; C09K003-32; B01J020-28; B01J020-32; C03C017-30; E21B043-22. APPLICATION: DE 84-3411759 30 Mar 1984. DOCUMENT TYPE: Patent CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Section cross-reference(s): 46 Surface-modified finely divided silicic acid particles (12 nm diam.) or silicate particles (65 nm diam.) were prepd. and used as demulsifiers in the breaking of heavy petroleum emulsions. The particles are insol. in water and in org. solvents. The particles are prepd. under anhyd. conditions by treating the solid particles (e.g., pyrolytic silicic acid) with suitable org. silanes (e.g., dimethoxymethyloctadecylsilane [70851-50-2] or triethoxyoctadecylsilane [7399-00-0]) or similar compds. (hexamethyldisilazane [999-97-3] or 1,6-hexane diisocyanate [822-06-0]). The demulsifiers, which can also contain addnl. surfactants, were superior in breaking a heavy Venezuelan crude petroleum emulsion compared with a com. surfactant (ethylene oxide-propylene oxide copolymer [9003-11-6]) or a com. surfactant contg. unmodified particles.
