IPC: C25B15/04
Filed: 1975-04-07
Abstract: 1474512 Anode adjustment in liquid-cathode cells OLIN CORP 7 April 1975 [18 April 1974] 14180/75 Heading C7B The anodes in a liquid-cathode cell are adjusted in groups, each group comprising a minor fraction of the whole, by (a) positioning the group at such a distance from the cathode that incremental anode movements produce relatively small current changes in the group, (b) moving the anode group at a constant rate towards the cathode while simultaneously measuring the current and using the measurement to calculate the rate of current density change per unit distance from the cathode, and (c) terminating movement when the said rate of change reaches a predetermined limit. Initially all anode groups may be in position (a), each being adjusted in turn until the whole cell is correct. Operation may be controlled by a digital computer with manual and/or automatic adjustment. The cells and anode groups may be selected randomly or serially. The rate of movement may be 0À1-1À0 mm/sec to an optimum electrode gap of 0À5-1À0 mm corresponding to a c.d. change-rate of 2-10 KA/M<SP>2</SP>/mm. The adjusted anode group may be raised after adjustment to prolong cell operative life. The procedure may be embodied into a process wherein the cell voltage coefficient V c  after a period of working is compared with a start-up coefficient S, adjustment being effected when the comparison value exceeds a desired limit. After adjustment, the following steps are optional: (1) the current is measured and if it continues to increase for more than a given time and/or if the magnitude of increase exceeds a given amount the anodes are raised; (2) current fluctuations over a period are measured and the anodes raised if excessive fluctuations occur; (3) the current is compared with an upper limit and the anodes raised if this is exceeded and (4) the frequency of adjustments over a period is noted and automatic control of adjustment is stopped when the frequency is too high, and a warning may be given. The coefficient S may be continuously recalculated during working and the anodes are renewed when the final S value exceeds a predetermined deviation from the original. Brine electrolysis in a horizontal Hg cathode cell with graphite or oxide-coated Ti anodes is specified.

Abstract: 1,262,670. Grinding and sifting cement. ESCHER WYSS Ltd. 18 March, 1969 [21 March, 1968; 24 Dec., 1968], No. 14268/69. Headings B2A and B2H. In a process for grinding and sifting cement in a closed circuit according to which raw cement is ground and the ground cement is thereupon sifted and divided into a coarse cement stream and a fine cement stream, the coarse cement stream being returned to the raw cement stream and the fine cement forming the finished product, a partial stream is taken from the fine cement stream and is re-introduced into the closed circuit. In Fig. 1, raw cement is supplied through a conduit 5 to the inlet 4 of a grinding mill 1 the outlet 7 of which is connected to a bucket elevator 6 which delivers the ground cement to a sifter 2 from which the coarse fraction is returned to the mill 1 via a conduit 3 and the fine fraction is directed via a conduit 3 to an adjustable selector valve 9 from which a portion of the fine fraction is discharged as the desired product through a conduit 10 and another portion is returned to the bucket elevator 6 via a conduit 11. In modifications, the other portion of the fine fraction may be led (a) to another elevator which conveys it to the sifter inlet, (b) to the mill inlet, or (c) partly to the mill inlet and partly to a further selector valve from which a fine-fraction portion is discharged as the desired product and another portion is returned to the elevator. The sifter may be of the type shown in Figs. 5 and 6. Raw cement is scattered in an inner chamber 53 by a plate 55 which is rotated with a vaned selector wheel 56 and a fan 57 by a common drive 58. An upward air current induced by the fan entrains the fine cement through the selector wheel and into a separating chamber 54 from which the air is recirculated into the chamber 53 through louvres 59. The degree of fineness of the fine cement is controlled by having selector vanes 517-519 of different radial dimensions and by radially movable slide elements 511.

Title: Improvements in or relating to the manufacture of steel or alloy steel in the open hearth furnace
IPC: C21C5/04
Filed: 1943-09-01
Abstract: 567,952. Steel manufacture; alloys. BETHLEHEM STEEL CO. Sept. 1, 1943, No. 14272. Convention date, April 29, 1942. [Classes 72 and 82 (i)] In the manufacture of steel in the open hearth furnace, the slag in the furnace is de-oxidised, shortly before tapping the heat when the latter has reached the desired carbon concentration, by adding finely divided ferro-silicon to the slag. The ferro-silicon is crushed to a size, e.g. 8 mesh, of sufficient weight to penetrate the slag and react therewith but not of sufficient weight to pass through the slag and into the steel bath. Shortly after the addition of the ferro-silicon alloying material such as ferromanganese or deoxidising elements such as aluminium may be added and the heat tapped as soon as these additions have melted. The addition of ferro-silicon is sufficient to retard substantially the transfer of iron oxide from the slag to the steel but not sufficient to cause reversion of phosphorus in the same direction.

Abstract: 1,134,488. Preparation of diphenyl silane diols. M. & T. CHEMICALS Inc. 29 March, 1967 [29 March, 1966], No. 14353/67. Heading C3S. Diphenyl silane diols are prepared by reacting #MgX with # a SiX b  in the presence of an inert hydrocarbon solvent, wherein # is a phenyl group which may be inertly substituted, (a+b) = 4 and a is 0 or 1, the #MgX being in a solution-complex with a cyclic ether and in a molar ratio of (b - 2) moles of #MgX per mole of # a SiX b , and the product obtained, # SiX b , is then hydrolysed, preferably after distilling off a quantity of the complexing cyclic ether, to precipitate the diphenyl silane diol. Typical compounds of the # a SiX b  type are silicon tetrachloride and tetrabromide and phenyl trichlorosilane and tribromosilane. Typical complexing agents are tetrahydrofuran, 2-methyl tetrahydrofuran, tetrahydropyran, 2-ethoxytetrahydropyran, N-methylmorpholine dihydropyran and tetrahydrofurfuryl ethyl ether. The preferred Grignard reagents are phenyl magnesium chloride and substituted phenyl magnesium chlorides. The preferred hydrocarbon solvents have a boiling range of 100-150‹ C. The exothermic reaction is maintained between 25‹ and 125‹ C. and the distillation at 85- 125‹ C. for 30-180 mins. generally removes 25-70% of the complexing agent leaving a reduced reaction mixture containing 1À5 to 3 moles of complexing agent per mole of magnesium added as the Grignard reagent. The hydrolysis is effected by adjusting the pH to between 6 and 7, using a buffer solution, preferred buffers being sodium or potassium bicarbonate, at 0-45‹ C. for 30-120 mins. and the precipitated product yields 80-95% of pure diphenyl silane diol. Reference has been directed by the Comptroller to Specification 795,772.

Patent GB-641438-A (GB)
Title: Process for the production of vinyl esters of organic acids
Filed: 1947-05-31
Abstract: Acetylene is reacted with organic carboxylic acids to produce vinyl esters, the acetylene being first contacted while under non-explosive conditions with a liquid volatile organic compound maintained at a predetermined temperature, the acetylene being thereby saturated with the vapour of the organic liquid; the ratio of acetylene to vapour is such that the mixture is non-explosive when introduced into the reaction zone (the temperature being high enough to prevent condensation of the vapour), although the temperature and pressure therein are such that the acetylene would normally be explosive.  The volatile organic liquid may be the acid used in the reaction, the ester produced, or other compounds such as hydrocarbons, heterocyclic compounds, esters or ethers, suitable compounds being mentioned.  A further inert diluent of this type may be used for the reaction if desired.  Zinc or cadmium salts of organic acids are used as catalysts, these being formed in situ if desired.  Many suitable acids are specified, aliphatic, aromatic, hydroaromatic and heterocyclic; polybasic acids or acid esters, cyclic hydroxy acids and phenyl-glycine may also be used, as well as mixtures of acids or acid esters such as those obtained from resins, from the saponification of fats or oils or from the partial oxidation of petroleum fractions, e.g. paraffin wax.  When hydroxy-acids are used, the presence of zinc salts as catalysts favours the production of esters rather than ethers, the latter being formed when using an alkaline catalyst as in Specification 641,436.  The vinyl esters produced may be recovered and purified by known methods, and polymerization inhibitors may be added.  The esters may be polymerized by the usual methods.  Examples show the reaction of acetylene with acetic, valeric and oleic acids.  Specifications 182,112, 285,095, 288,707, [all in Class 2 (iii)], 378,873, 572,910, 578,405, 581,501 and U.S.A.
