Abstract:

This invention relates to a process for the preparation of quinacridone pigments by (a) heating, at a temperature of about 80. degree. C. to about 145. degree. C. , a reaction mixture containing (i) 2,5-dianilinoterephthalic acid, a 2,5-dianilino-3,6-dihydroterephthalic acid ester, and/or a derivative thereof, (ii) about 3 to about 15 parts by weight, per part of component (a)(i), of a dehydrating agent, and (iii) about 0. 1 to about 15 percent by weight, based on component (a)(i), of one or more non-quinacridone pigments, with the proviso that if component (a)(i) is a 2,5-dianilino-3,6-dihydroterephthalic acid ester or a derivative thereof, reaction step (a) additionally comprises an oxidation step; (b) drowning the reaction mixture from step (a) by adding said reaction mixture to about 3 to about 15 parts by weight, per part of component (a)(i), of a liquid in which the quinacridone pigment is substantially insoluble; (c) isolating the quinacridone pigment; (d) optionally, conditioning the quinacridone pigment; and (e) optionally, blending the resultant pigment with one or more quinacridone derivatives.

Abstract:

The scroll compressor 10 includes a housing 12, a fixed scroll 18, an orbital scroll 24, an axial thrust and rotation prevention assembly 46, and an orbital scroll drive. The orbital scroll drive includes a crankshaft 74 rotatably journaled in the housing 12. The crankshaft includes an integral disk 76 and an eccentric crank pin 78 with a lubrication passage 96. An eccentric bushing 80 is journaled on the crank pin 78 and in a boss 82 on the orbital scroll by a needle bearing 81. An eccentric bushing retainer 102 has a shank portion 104 that is pressed into the lubrication passage 96 and an enlarged head portion 106 which holds the eccentric bushing 80 on the crank pin 78. If the eccentric bushing retainer 102 becomes partially unseated from the lubrication passage 96, the surface 114 on the enlarged head portion 106 will contact a surface 116 on the end plate 26 of the orbital scroll 24 and keep the eccentric bushing 80 properly positioned within the compressor housing 12. A passage 120 may be provided in the eccentric bushing retainer 102 to control lubrication of the eccentric bushing 80. The eccentric bushing retainer 102 can be made from plastics and other materials which will act as a bearing surface in the event contact is made with the surface 116 on the orbital scroll 24.

US Classification:

106411

Abstract:

This invention relates to water-dispersible phthalocyanine pigment formulations that are mixtures of (a) about 60 to about 99. 5% by weight, based on the total amount of components (a) and (b), of a conditioned metal phthalocyanine pigment, and (b) about 0. 5 to about 40% by weight, based on the total amount of components (a) and (b), of a water-insoluble sulfonated phthalocyanine having the formula Pc(SO. sub. 2 OR). sub. x (I) wherein Pc represents a phthalocyanine moiety; R is H or M, wherein M is a monovalent metal, divalent metal, trivalent metal, or ammonium cation, and x is a from about 0. 2 to about 4.

International Classification:

C09C 1/42

Abstract:

Clay materials useful as binding agents in green sandcasting and other molding processes are discussed, as well as methods of preparing such clay materials. The clay materials may be chemically treated. For example, a natural clay may be combined with one or more reducing agents, such that an amount of iron present as ferric iron (Fe) in the natural clay is at least partially reduced to ferrous iron (Fe) in the chemically-treated clay. The chemically-treated clay may exhibit greater water absorption, binding properties, and/or sintering properties as compared to an untreated, natural clay.
