Title: Improvements in or relating to the preparation of metal or silicon carbides
IPC: C01B31/30
Filed: 1952-08-20
Abstract: Metal or silicon carbides such as those of calcium, aluminium, iron or silicon and a gas containing carbon monoxide with or without hydrogen are simultaneously produced by feeding a mixture of carbonaceous solid fuel and the oxide, hydroxide or carbonate corresponding to the desired carbide to a blast furnace-like generator and blowing into the furnace a gas consisting of at least 50 per cent. by volume of oxygen, the remainder being either or both of steam and carbon dioxide, the proportion of the gas and mixture and the amount of carbon present in the furnace being adjusted in relation to the oxide, hydroxide or carbonate so that when sufficient carbon is burnt to attain carbide-forming temperatures, there will be sufficient remaining unburnt to combine with the oxide, hydroxide or carbonate to form the respective carbide.  According to examples, (i) a generator was continuously filled with a charge of 80 parts of coke and 30 parts of limestone, which charge passed through a preheating zone to a furnace hearth where part of the coke was burned with an oxygen-containing blast introduced through a plurality of tuyeres, the blast preheated to 120 DEG  C. consisting of 66 per cent. oxygen, 30 per cent. steam and the remainder nitrogen.  Raw carbide in a molten state was formed and was discharged from the bottom of the hearth; the gas withdrawn from the top of the generator consisted of 80 per cent. carbon monoxide, 13 per cent. hydrogen and small quantities of nitrogen and carbon dioxide.  (ii) A generator was filled with a briquetted charge of coke and lime in the ratio of 4 to 1 by weight and an oxygen blast consisting of technical oxygen and carbon dioxide with a small amount of nitrogen was passed in at 25 DEG  C.  The raw carbide was withdrawn as in Example (i) and the gas withdrawn from the top of the generator consisted of carbon monoxide with small quantities of nitrogen and carbon dioxide. The oxygen content of the blast may be reduced by 1 per cent. for each 100 DEG C. of preheating.  The gas mixture may be employed as starting materials for the methanol-or Fischer-Tropsch-synthesis.

Title: Process for producing 4-substituted 1, 2-diaryl-3, 5-dioxo pyrazolidines
Filed: 1955-07-22
Abstract: 4 - Substituted 1 : 2 - diaryl - 3 : 5 - dioxopyrazolidines are prepared by reacting halogenated unsaturated hydrocarbons, having at least one halogen atom on a singly bound and at least one on a doubly bound carbon atom, with a 1 : 2-diaryl-3 : 5-dioxopyrazolidine or with its malonic component, and (after condensation with a 1 : 2-diarylhydrazine in the latter case) treating the resulting diaryldioxopyrazolidines, substituted in position 4 by one or two haloalkenyl groups, with a reducing agent, either directly or after conversion into the corresponding g -oxoalkyl derivatives. Alternatively the halogenated unsaturated hydrocarbon, malonic acid or a reactive derivative thereof, and hydrazobenzene are condensed simultaneously by the gradual addition thereto of an alkaline condensing agent.  The haloalkenyl substituent or substituents may be converted to alkenyl by mild reduction methods (e.g. with hydrogen at low temperature in the presence of a palladium catalyst, or with an alkali metal and alcohol), or to alkyl by more vigorous reduction (e.g. with hydrogen at increased temperature and/or pressure in the presence of Raney nickel, or with aluminium or its alloys in an alkaline aqueous medium), or may be converted to g -oxoalkyl by the action of conc.  H2SO4 followed (after evolution of HCl has ceased) by decomposition of the product with water or ice, the g -oxoalkyl group or groups then being reduced.  In examples: (1) 1 : 2-diphenyl-3 : 5-dioxopyrazolidine is stirred with 1 : 3-dichlorobutene-2 and caustic soda lye to produce 1 : 2-diphenyl - 3 : 4 - dioxo - 4 - g  - chlorocrotylpyrazolidine, which is reduced in caustic soda solution with hydrogen in the presence of Raney nickel to the sodium salt of the 4-n-butyl compound; 4-bis-substituted compounds are obtained if the amounts of 1 : 3-dichlorobutene-2 and NaOH are doubled and the reaction time prolonged; (2) g -chlorocrotylmalonic acid diethyl ester (from diethyl malonate and 1 : 3-dichlorobutene-2 in a solution of sodium ethoxide in ethanol) is heated with hydrazobenzene in a similar solution, and the product, dissolved in ethanol, is reduced with hydrogen in the presence of palladium on calcium carborate to 4 - buten - (2) - yl - 1 : 2 - diphenyl - 3 : 5 - dioxopyrazolidine; (3) a solution of sodium ethoxide in ethanol is added gradually to a warm mixture of hydrazobenzene, diethyl malonate and 1 : 3-dichlorobutene-2, and the product, dissolved in dioxan and n-butanol, is reduced with sodium to the product of (2); (4) the reduction in (1) is effected by means of aluminium-nickel alloy; (5) 4 - g  - chlorocrotyl - 1 : 2 - diphenyl - 3 : 5-dioxopyrazolidine is reacted with conc. H2SO4 and the product decomposed with water, and the resulting 4-(g -oxobutyl) compound is reduced with hydrazine hydrate, potassium hydroxide and diethylene glycol to the 4-n-butyl compound.  Additional halogenated unsaturated hydrocarbons specified are 1 : 3-dichlorohexadiene-3 : 5 and trichlorohexenes.

Abstract: 1464873 Mounting reels on shafts; clutches FORDS (FINSBURY) Ltd 30 April 1974 [4 May 1973] 21418/73 Headings F2U and F2C A chuck for coupling a winding core to a mandrel on which the chuck is fixed comprises gears movable radially outwards together along surfaces 34 of the chuck to grip the core, the gears 38 engaging teeth cut in the surfaces 34. The gears move together through engagement with a rotatable member having radial slots 43 engaged by portions 44 of the gears 38. When the gears are at the radially innermost part of a surface 34 they project sufficiently for a core to engage at least one to thereby move all the gears radially outwards on rotation of the core relative to the mandrel. The coupling is selftightening during drive and the rotation of the mandrel may cause the coupling if the resistance of the core to rotation is sufficient. A friction coupling between a chuck and mandrel is shown in Fig. 7, this having members 75 fixed for rotation with the mandrel 60 by pins 76 and friction members 74 between members 75 and the chuck 10, an axial force causing the friction grip, which slips under strain.
