Ice pack material having sherbet-like consistency

Ice pack material having sherbet-like consistency. Nakai, Noboru (Katsuraya Co., Ltd., Japan). Japan. JP 52008272 B4 8 Mar 1977 Showa, 4 pp. (Japanese). (Japan). CODEN: JAXXAD. CLASS: IC: C09K005-00. APPLICATION: JP 67-6298 2 Feb 1967. DOCUMENT TYPE: Patent CA Section: 63 (Pharmaceuticals) A mixt. of materials such as CM-cellulose [9004-32-4] and poly(vinyl chloride) (PVC) [9002-86-2], C12-18 higher alcs., urea, surfactants, and water is an excellent cooling material which keeps sherbet-like consistency but does not become rock solid upon freezing. The mixt. filled in a water-proof bag is an excellent cooling agent which can be used as an ice pack to cool head, arms, legs, etc. Thus, cM-cellulose 6, oleyl alc. [143-28-2] 0.5, Na alkylbenzenesulfonate 2, and urea [57-13-6] 10 kg and hot water to a total of 100 kg were mixed, stirred, and cooled. The mixt. (500 g each) was filled in water-proof bags. The product had sherbet-like consistency after being kept at -15.degree. for 12 h.

Effect of additives in low-viscosity lubricating oils on the deep-drawing capacity of aluminum sheets

Effect of additives in low-viscosity lubricating oils on the deep-drawing capacity of aluminum sheets. Murata, Hiroshiga; Takahashi, Tsuneo (Abt. Metall., Tokyo Metropolitan Ind. Technol. Cent., Tokyo, Japan). Aluminium (Duesseldorf), 61(7), 521-4 (German) 1985. CODEN: ALUMAB. ISSN: 0002-6689. DOCUMENT TYPE: Journal CA Section: 56 (Nonferrous Metals and Alloys) Section cross-reference(s): 51 The effect of 1% additives to low-viscosity lubricating mineral oils (VG8, 32, 100, and VG2L) was studied on the deep drawability (0.657) of 1 mm thick Al [62200-40-2] sheet contg. Cu 0.02, Si 0.14, Fe 0.6, and Mn, Zn, and Ti each 0.01% at a uniform blank holder force of 2 kN, 12.5 vs. 60 mm/min, and drawing ratio 1.95. The additives were oleic acid [112-80-1], oleyl alc. [143-28-2], and Me oleate [112-62-9]. The drawing ratio limit increased gradually with increasing oil viscosity. The addn. of oleic acid or oleyl alc. decreased considerably the drawing force. Low-viscosity oil resulted in improved surface roughness, high viscosity and increased drawing speed in coarse surface roughness of deep-drawn cups. The surface defects were not eliminated by addn. of oleic acid to a low-viscosity lubricating oil. The Al transfer to the tool increased with decreasing oil viscosity at const. drawing speed and decrease in drawing speed. Oleic acid additive had the best effect.
