Title: Manufacture of cottage cheese
IPC: A23C19/05
Filed: 1963-04-29
Abstract: Cottage cheese of increased shelf life is prepared by treating milk at a high temperature to effect at least 40% (preferably between 60 and 80%) denaturation of the serum protein in the milk, adding an acid-producing starter to the milk to form cottage cheese curd and whey, cutting the cheese curd when the acidity is between 0.40% and 0.44% (expressed as equivalent per cent of lactic acid), and heat treating the curd at temperatures between 130 DEG F. and 145 DEG F. for at least 45 minutes at 130 DEG F. and for equivalently diminished periods of time at temperatures thereabove.  The heat treated curd is then creamed with a pasteurised and homogenised creaming mixture having a temperature above 140 DEG F. so that the cream and curd mixture is maintained at temperatures which inhibit microbial survival and growth until the cheese is packaged and the package is sealed; the creaming mixture is prepared by blending cream, skim milk and salt.  A 60% denaturation of the milk serum protein can be accomplished by holding the milk at 200 DEG F. for 40 seconds, at 260 DEG F. for 12 seconds or at 300 DEG F. for zero time.  The heat treatment of the curd, which should be for not longer than 2 1/2 hours, may be carried out before whey is drained from the curd or by washing the curd with hot water after draining the whey.  Detailed examples of the preparation of cottage cheeses are disclosed.

Patent GB-1499406-A (GB)
Title: Separation of cobalt and nickel
IPC: C22B3/38
Filed: 1975-04-24
Abstract: 1499406 Separation of cobalt and nickel values INCO EUROPE Ltd 7 April 1976 [24 April 1975] 17025/75 Heading C1A Cobalt values (and copper values if also present) are separated from nickel values in an aqueous acid sulphate, chloride or nitrate leach solution by contacting the solution with a solution, in an inert substantially water-immiscible organic liquid, of the nickel salt of an organo-phosphoric acid of formula (RO) 2 PO(OH), wherein each R, which may be the same or different, is hydrogen or substituted or unsubstituted alkyl, aryl or alkaryl, provided that not more than one R is hydrogen, each R group contains at least 8 carbon atoms and the phosphoric acid molecule contains at least 12 carbon atoms, so as to transfer cobalt values from the aqueous leach solution to the organic solution; separating the organic leach solution containing transferred cobalt values from the aqueous raffinate solution; and crystallizing some or all of the raffinate solution to produce crystals of nickel sulphate, chloride or nitrate. The preferred organophosphoric acid is di-(2-ethylhexyl)phosphoric acid. Preferred organic solvents are kerosine and naphtha. It is preferred to scrub the cobalt-loaded organic extract with sulphuric, hydrochloric or nitric acids or an aqueous solution of cobalt sulphate, chloride or nitrate in order to increase the Co/Ni ratio therein prior to stripping the cobalt values. The cobalt values may be stripped from the organic solvent by means of sulphuric, hydrochloric or nitric acids to produce an aqueous solution of the corresponding cobalt salt and a solution of the organo-phosphoric acid itself. The organo-phosphoric acid may then be re-converted to its nickel salt (optionally after conversion to its alkali metal or ammonium salt first) by treatment with an aqueous nickel sulphate, chloride or nitrate solution (together with an aqueous alkaline solution in the case of direct re-conversion). The organic solution of the organo-phosphate nickel salt is then re-cycled to the cobalt extraction step. The aqueous solution of nickel sulphate, chloride or nitrate used in re-conversion may be the mother liquor obtained on crystallizing the aqueous raffinate obtained from the initial cobalt extraction step. The process may be performed without an emulsion inhibitor in the organic phase.

Filed: 1940-11-29
Abstract: 542,160. Sulphonamido compounds. CHINOIN GYOGYSZER ES VEGYESZETI TERMEKEK GYARA R. T. (Dr. Kereszty and Dr. Wolf). Nov. 29, 1940, No. 17072. Convention date, Oct. 12, 1939. [Class 2 (iii)] Sulphonamido compounds are prepared by interaction, in the presence of a tertiary base containing the pyridine nucleus, of a 2-aminothiazole or α-aminopyridine with 2-aminothiazoles which contain arylsulphonyl groups in both 2- and 3-positions. Intramolecular rearrangement takes place with the migration of the arylsulphonyl group in 3-position to the amino group of the aminothiazole or aminopyridine. The di(arylsulphonyl)-2-aminothiazoles used as starting materials may be regarded as derived from thiazolone-2-imide, which is the tautomeric form of 2-aminothiazole, and are prepared by the processes of Specifications 32419/39 (as open to inspection under Sect. 91), and 620,744. According to the examples, (1) interaction of 3-(p-acetaminobenzenesulphonyl) - thiazolone - 2 - benzenesulphimide with 2-amino-4-methylthiazole produces 2-benzenesulphonylaminothiazole and 2- (p - acetaminobenzenesulphonylamino) - 4 - methylthiazole, which latter is hydrolysed to split off the acetyl group ; if 2-aminothiazole is used in place of 2-amino-4-methylthiazole, 2 - benzenesulphonylaminothiazole and 2 - p - aminobenzenesulphonylaminothiazole are obtained ; (2) interaction of 3- (p - acetaminobenzenesulphonyl) - thiazolone - 2-benzenesulphimide with α-aminopyridine gives rise to 2-benzenesulphonylaminothiazole and 2 - p - acetaminobenzenesulphonylpyridine from which the p-amino body is obtained by hydrolysis; (3-5) di-(p-acetaminobenzenesulphonyl) - 2 - amino - 4 - methylthiazole is re-acted with 2-amino-4-methylthiazole to give 2 - p - acetaminobenzenesulphonylamino - 4 - methylthiazole ; the acetamino group in the starting material may be replaced by the nitro group or may be absent altogether. In each of the examples, the re-actants are heated together for some hours with pyridine on a water bath. 3 - (p - Acetaminobenzenesulphonyl) - thiazolone-2-benzenesulphimide is prepared by first forming 2-benzenesulphonylaminothiazole by interaction of 2-aminothiazole with benzenesulphonyl chloride and then treating it with 2-p-acetaminobenzenesulphonyl chloride in presence of caustic soda solution and acetone.
