Heat storage material. Kamohara, Hideaki; Yanadori, Michio; Miyamoto, Seigo; Koike, Keiichi (Hitachi, Ltd. , Japan). Eur. Pat. Appl. EP 92199 A1 26 Oct 1983, 17 pp. DESIGNATED STATES: R: DE, FR, GB. (English). (European Patent Organization). CODEN: EPXXDW. CLASS: IC: C09K005-06. APPLICATION: EP 83-103671 15 Apr 1983. PRIORITY: JP 82-62406 16 Apr 1982; JP 82-203614 22 Nov 1982. DOCUMENT TYPE: Patent CA Section: 52 (Electrochemical, Radiational, and Thermal Energy Technology) A heat-storage material for air-cooling systems comprises HOAc [64-19-7] or a mixt. of HOAc and 31 acetate and is further added with 31 anhyd. 64-19-7 and 12125-02-9 are cas registry numbers of chemicals which are used as reagents here. halide as nucleating agent to prevent supercooling. Thus, a heat-storage material was prepd. from HOAc with NaOAc [127-09-3] 5, KOAc [127-08-2] 3, and CaCl2 0.01%. The material was subjected to 20 cycles of heating to 25° and then cooling to -5°. Supercooling was <0.1° vs. 5.5-6° for material without CaCl2. .

Polyester films

Polyester films. (Teijin Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 58177316 A2 18 Oct 1983 Showa, 5 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: B29D007-02; C08L067-02. ICA: C08K003-00; C08K005-09. APPLICATION: JP 82-59743 12 Apr 1982. DOCUMENT TYPE: Patent CA Section: 38 (Plastics Fabrication and Uses) Polyester films are prepd. by extruding mixts. of thermoplastic polyesters 100, inorg. powders 0.01-2, and ethylene glycol-sol. alkali metal compds. 0.0001-0.0025 part (as metal) and drawing biaxially. Thus, a mixt. of poly(ethylene terephthalate) [25038-59-9] 100, clay 0.25, and AcONa [127-09-3] (as Na) 0.0005 part was extruded at 285° to a film, drawn 3.6:1 in the machine direction and 3.9:1 in the transverse direction, and heat-treated at 225° to give a uniform film with a good surface.Except for chemicals metioned above, 1344-28-1 and 1310-73-2 are also used. .
