Title: Upgrading of calcareous rock phosphate
Inventor: BEN-ARI CARMELA
IPC: C05B11/02
Filed: 1960-12-09
Abstract: Calcareous phosphate ore is upgraded by calcining and wet slaking after which the calcium hydroxide is separated from the phosphate concentrate as a slurry.  The calcium hydroxide which carries with it some of the phosphate ore is reacted with ammonium chloride solution or solid to form calcium chloride and ammonia in solutions.  Residual phosphate is removed for example by filtration.  The solution is then heated to remove the ammonia which is passed into solutions containing magnesium chloride thus precipitating magnesium hydroxide and forming ammonium chloride in solution, as in the parent Specification.  The mixture is then filtered and the ammonium chloride liquor is either evaporated to dryness or added as such to further calcium hydroxide.  The wet slaking is preferably carried out at the boil and the resultant slurry may be concentrated to a solid:liquid ratio between 1:4 and 1:5 in which case the ammonium chloride is added as a solid, or it may be evaporated to dryness in which case ammonium chloride liquor is employed.

Abstract: A crude mixture comprising a cycloaliphatic alcohol and a cycloaliphatic ketone and containing acidic material is improved by treating the mixture with an anhydrous, mild alkaline compound by (i) contacting the mixture in the vapour phase with the anhydrous alkaline compound or (ii) distilling the mixture in the presence of the anhydrous alkaline compound or (iii) refluxing the mixture in the presence of the anhydrous alkaline compound. Specified crude mixtures comprise cyclohexanol or a cyclohexanol containing an alkyl substituent in the nucleus.  The distillation or refluxing may be carried out in an atmosphere free from molecular oxygen.  Specified alkaline compounds are alkali metal carbonates and alkoxides.  Also, cyclohexanone or an alkylcyclohexanone is obtained by the partial oxidation of cyclohexane or an alkylcyclohexane, washing the resulting alcohol-ketone mixture with a dilute alkali, subjecting the alkali-washed product to fractional distillation to yield a cut rich in cyclohexanol or an alkylcyclohexanol, treating the cut as described above and subjecting the treated cut to catalytic dehydrogenation.  Specified dehydrogenation catalysts are copper, brass and zinc oxide.  The alkali-washed product may be subjected to distillation in the absence of oxygen and/or in the presence of an oxygen-scouring substance prior to the distillation with the anhydrous mild alkaline compound.  Examples are given for the production of cyclohexanone.

Abstract: 1288008 Thread guides; yarn heating ZINSER TEXTILMASCHINEN GmbH 17 Sept 1970 [19 Sept 1969] 44489/70 Headings DID and D1F In e.g. a draw twisting machine thread is guided by a grooved roller 3 which reciprocates in the direction of the arrow A. The thread then passes about an upper roller 5 driven frictionally by a lower roller 7. The roller 5 is mounted on an arm 20. The roller 7 constitutes a first guide element from which the thread passes to a second guide element, which may be the surface 23 of a heating plate 9, which is mounted at approximately 90‹ to the first guide element looking in the direction of thread travel. Intermediate the guide elements is a guide piece 16 which may comprise a fixed rod or a roller and is mounted at some angle (preferably between 30‹ and 60‹) to the first guide element, see Figs. 3 and 4 not shown. With this arrangement the reciprocation of the thread in the direction of arrow A produces a proportional reciprocation across the second guide element in the direction of the arrow B, Fig. 1 (not shown), hence preventing local wear of the guide elements. The thread finally passes about a roller 11 and guide roller 12, the roller 11 rotating with a lower peripheral speed than the roller 7 to produce a drawing effect. The guide piece 16 may be straight or have a curved edge e.g. sinusoidal, see Fig. 4 not shown, to give the desired proportionality of the reciprocations involved.
