Title: Improvements in or relating to the separation of minerals from ores
IPC: B03D1/02
Filed: 1938-09-12
Abstract: 518,852. Concentrating ores : cements. SMIDTH & CO. AKTIESELSKAB, F. L. Sept. 12, 1938, No. 26587. Convention date, Sept. 10, 1937. [Class 82 (ii)] [Also in Group V] To render more suitable for use in cement manufacture an argillaceous limestone, marl, chalk, or similar ore which contains an excess of one or more minerals such as aluminium and magnesium silicates, the ore or part of the ore, ground to such an extent that at least the excess of the silicates &c. is present as free particles in the fines, is subjected to froth flotation and the reject from the froth flotation is subjected to'hydraulic classification under such conditions. that the excess of the silicates &c. is removed as classifier overflow. If the excess minerals can be freed by partial grinding, the ore may be classified after grinding and only the fines subjected to the froth flotation and subsequent classification, in which case the flotation concentrates and the coarse particles from the subsequent classification may be added to the untreated part of the ore, preferably after further grinding of the latter, to produce the raw material for the cement, free silica being added if required. The flotation step is preferably such as to concentrate calcite in the froth, the tailings constituting the reject which is subjected to hydraulic classification. In treating an ore containing graphitic carbon, the carbonaceous matter may be removed by a preliminary flotation using, for example, fuel oil and a frothing agent, or it may be depressed during the calcite flotation by the addition of a lignin sulphonate as described in Specification 515,592. Lignin sulphonates may also be added, either prior to flotation or prior to the subsequent classification, as dispersing agents, as described in Specification 515,601. To float the calcite a fatty acid collecting agent is used, e.g., oleic acid or fish oil fatty acids, fatty acid emulsions, preferably a stabilized emulsion such as those described in Specification 515,606, and 515,607, or saponified tall oil preferably in conjunction with, e.g. dispersed with, mineral oil. Stage oiling is normally desirable. The frother may be cresylic acid or a mixture of aliphatic alcohols obtained, with methanol, by the catalytic hydrogenation of carbon oxides. The concentrates may be cleaned, and in both the rougher and the cleaning steps the air supply to the cells is preferably reduced below normal. The tailings from the rougher cells are diluted and subjected to hydraulic classification, e.g., in a bowl or rake classifier, on a concentrating table, or, preferably, in a Dorr hydro-separator, the lighter particles, constituting the excess minerals being removed as overflow. The drawing shows a typical plant used in the treatment of a carbonaceous argillaceous limestone from which micas are removed in order to reduce the proportions of alumina, magnesia, and silica, a two-stage grinding and a preliminary classification preceding the flotation treatment. Specifications 426,423 and 478,275 also are referred to.

Title: Improvements in or relating to a method of insolubilising continuously travelling tows of artificial filamentary products
IPC: D01F4/00
Filed: 1947-10-06
Abstract: Continuously travelling tows of artificial filamentary products obtained by spinning solutions of vegetable seed globulins or phospho-proteins in aqueous alkaline or other aqueous solvent media into acidified saline coagulating baths, are insolubilized by advancing the tow through a tubular passage by means of a turbulent stream of an aqueous formaldehyde solution saturated with sodium chloride and containing sodium sulphate or magnesium sulphate and having a pH of 4 to 6, and then advancing the treated tow through <PICT:0637025/IV (a)/1> another tubular passage by means of a turbulent stream of an aqueous formaldehyde solution strongly acidified with sulphuric acid and saturated with sodium sulphate or magnesium sulphate, this second solution being at a higher temperature than the first. The vegetable seed globulins may be peanut proteins, and the phospho-protein may be casein.  The tubular passage is preferably of narrow diameter and may be either straight or arranged in helical form, but in both cases the liquid is passed through under such conditions as to be in turbulent flow.  In the example, a matured caustic soda solution of groundnut globulin prepared from a solution containing peanut globulin, caustic soda and sodium sulphite is extruded through a spinneret 1 into a coagulating bath 2 containing sodium sulphate and sulphuric acid.  The resulting tow 3 is then stretched between godets 4 and 5 and led over godet 6 through a device 8 having a reciprocating motion radial to the centre of the ring trough 7 and into the trough, which contains a saturated acidified solution of sodium chloride.  The tow is taken up and stretched between godets 1 and 12, passed over godet 13 and then through a vertical helical coil 15 through which a formaldehyde solution saturated with sodium chloride and containing sodium sulphate is passed at 70 DEG  C.  After stretching between godets 17 and 18 the tow is passed through another helical coil 20 containing a formaldehyde solution acidified with sulphuric acid and saturated with sodium sulphate at 95 DEG  C., and is finally washed and dried. Specifications 513,910, 597,497 and 623,460 are referred to.

Title: Internal combustion engine
IPC: F02N19/10
Filed: 1964-06-29
Abstract: 1,089,545. Engine cooling systems; concentric-tube heat exchangers. R. D. QUINTON. June 21, 1965 [June 29, 1964], No. 26871/64. Headings F4S and F4U. When the temperature of an I.C. engine falls below a predetermined optimum value the coolant returning to the engine block at 30 is heated by the exhaust gases in a heat exchanger 29 comprising an annular coolant jacket 5 spaced from the exhaust pipe 4 by a chamber 32 with fins 6, 7. The coolant returning from the radiator 2 is always forced by a pump 16 through the annular jacket 5 but so long as the air in the chamber 32 is at rest no heat exchange takes place between the exhaust gases in the pipe 4 and the coolant in the jacket 5. When the temperature of the coolant falls below a preset value a thermally responsive switch 14 starts a pump 11 to force an intermediate fluid, e.g. air through the chamber 32 the fins 6, 7 causing turbulence in the fluid to transfer heat from the exhaust pipe 4 to the coolant. If air is pumped by the pump 11 it may exhaust through a pipe 8 to the atmosphere; other intermediate fluids may be recirculated through a pipe 12. The pump 11 may be replaced by a Venturi pipe in the exhaust drawing air through the chamber 32. In a modified heat exchanger 29 the exhaust pipe 4 and the jacket 5 are relatively rotatable about their common axis and the fins 6, 7 are replaced by two series of spaced flat radial segments attached to the jacket 5 and pipe 4 respectively. By relative rotation the segments may be made to overlap leaving axial passages for the intermediate fluid to flow non-turbulently so that no heat transfer occurs. The pump 11 may then run continuously, and the segments are adjusted by the switch 14, when the temperature of the coolant falls, so that they do not overlap, thus causing turbulence and heat transfer. The coolant leaving the engine block at 31 passes through a cabin heater 20 to the radiator 2 or to a by-pass 17 controlled by a thermostatic valve 18. A fan 22 blows air through a duct 21 to the cabin or for demisting.
