Title: Improvements in method and apparatus for introducing solid materials into molten metal
IPC: C21C7/00
Filed: 1953-11-10
Abstract: 748,474. Making and refining alloys; refining steel and other metals. AIR REDUCTION CO., Inc. Nov. 10, 1953 [Dec. 9, 1952], No. 31143/53. Classes 72 and 82(1). A finely divided solid of low density such as calcium carbide or magnesium metal is introduced into molten metal to effect a refining reaction or for alloying by forming a gasfluidised stream containing at least one-half pound of solid per cubic foot of gas and projecting the stream at a velocity exceeding 25 ft./sec. into the molten metal beneath the surface so that the solid particles penetrate the gas-molten metal interface into the molten metal. As shown, gas (which may be oxidising such as air or CO 2 , or neutral, inert or reducing such as A, N 2  or propane) from a cylinder 9 passes through regulator valves and a flowmeter to the fluidising column 8 which is maintained approximately 2/3 full of calcium carbide of minus 48 mesh from a funnel 7, and a funnel 20 draws off a stream of carbide and gas for delivery through pipe 17 to the receptacle 5 of molten iron. The velocity of the fluidising gas in the column 8 is preferably 0À1-0À3 ft./sec., and the gas leaving the top of the column via standpipe 14 is filtered at 15 and escapes to atmosphere at 16, a line 21 enabling gas to be supplied to a venturi-type ejector at the base of cone 20. Any block in the line 17 may be removed by opening valve 24 to admit a purging stream of gas. U.S.A. Specification 2,577,764 is referred to.

Patent GB-653522-A (GB)
Title: Improvements in or relating to the production of guanadine sulphates
Filed: 1947-11-26
Abstract: Guanidine sulphates are prepared by the reaction of sulphamic acid or one of its salts with urea.  The reactants are fused and then heated to a suitable temperature for a short period to permit the reaction to occur.  Suitable high-boiling, inert solvents and/or diluents may be used.  The preferred temperature of the reaction is in the range 190-300 DEG  C.  Sulphamic acid salts mentioned as starting materials are ammonia, aluminium, potassium, sodium, barium, calcium, magnesium and like sulphamates and also sulphamic acid addition salts of the amines of the aliphatic, carbocyclic and heterocyclic series such as methylamine, diethylamine, di - n - dodecylamine, aniline, morpholine sulphamates.  Preferably 1 mol. of urea is used to 1/2 -3 mols. of sulphamate.  The product is then predominantly diguanidine sulphate but the more acidic monoguanidine sulphate may be prepared from it by acidifying the diguanidine sulphate with sulphuric acid.  A less soluble guanidine salt, e.g. a picrate, carbonate or phosphate may be obtained by the action of the appropriate acid on the sulphate.  Free guanidine may be obtained by dissolving the dry reaction mixture in an alcohol, adding excess potassium hydroxide and obtaining the guanidine from solution by the usual methods.  In the examples, guanidine sulphate is prepared by reaction p  between (a) urea and ammonium sulphamate; (b) urea and sulphamic acid; (c) urea and sodium sulphamate (prepared by action of sulphamic acid on sodium hydroxide); (d) urea and calcium sulphamate (prepared by the action of sulphamic acid on calcium hydroxide); in this example the guanidine sulphate is treated with picric acid to give guanidine picrate; (e) urea and dodecylamine sulphamate (prepared by the action of dodecylamine on sulphamic acid).

Filed: 1957-10-07
Abstract: The invention comprises products of the general formula <FORM:0822119/IV (a)/1> group, each Z which may be the same or different is a hydrogen atom, a carboxyl, carbalkoxy or hydroxy group or an alkyl radical with a straight or branched chain and having 1 to 6 carbon atoms which if desired can carry one or more hydroxy, etherified hydroxy, carboxy, carbalkoxy, amino, substituted amino, or aldehyde groups, or one or more further N,N - bis - (b  - chloroethyl) - thiophosphoramido rings, and n is a whole number from 1 to 3.  They may be obtained by reacting a compound of the general formula <FORM:0822119/IV (a)/2> in which each X1 is a halogen atom, preferably a chlorine atom, with a compound of the general formula <FORM:0822119/IV (a)/3> in which each Z and n are as defined above and a is a hydroxy group or the group -NH-Z wherein Z is as defined above in an inert solvent in the presence of an acid-binding agent at low or elevated temperature.  The acid binding agent is preferably triethylamine or it may be an excess of a basic alcohol of the last given formula, e.g. ethanolamine.  Specified inert solvents are dioxane and benzene.  Specified compounds of the last given formula are glycols, alkanolamines, hydroxy amino acids or the corresponding amino alcohols, and polyhydroxy compounds, e.g. carbohydrates such as sugars.  Instead of using alkanolamines or glycols in the reaction it is possible to use functional derivatives of these compounds, e.g. N-acyl derivatives of alkanolamines or esters of glycols or N,O-diacyl derivatives, the acyl group being eliminated during the reaction.  In examples, N,N-bis-(b -chloroethyl)-thiophosphoric acid amide dichloride is reacted with ethanolamine, ethylene glycol, 1-amino-propan-3-ol, b -hydroxyethyl methylamine and D-sorbitol respectively to form N,N-bis-(b -chloroethyl) - N1,O - ethylene thiophosphoric acid diamide, N,N - bis - (b  - chloroethyl) - O,O1-ethylene thiophosphoric acid amide, N,N-bis-(b  - chloroethyl) - N1,O - propylene thiophosphoric acid diamide, N,N-bis-(b -chloroethyl)-N1 - methyl - N1,O - ethylene thiophosphoric acid diamide and N,N,-bis-(b -chloroethyl)-O,O1-sorbitol-thiophosphoric acid amide respectively.  The products are stated to be effective as agents for inhibiting cell growth in the treatment of malignant growths.  The compound N,N-bis-(b  - chloroethyl) - thiophosphoric acid amide dichloride used as starting material in the examples is obtained by heating N,N-bis-(b -chloroethyl)-amine hydrochloride to boiling with an excess of phosphorus sulphochloride.

Filed: 1959-09-17
Abstract: Racemic amino acids such as DL-glutamic acid and DL-threonine are continuously resolved by introducing a saturated solution of said racemic acid into the bottom of a resolution tower at such a rate as to fluidize crystal seeds of one of the optically active isomers of said compound fed in at the top, extracting grown and precipitated crystals in the solution at the bottom and causing said solution which contains the other optical isomer to overflow at the top at such a rate that it removes with it any fine crystals of racemate or of the other optically active isomer which might be formed.  The process may be conducted in a number of resolution towers for L- and D-isomers connected alternately in series, or in a number of pairs of D- and L- resolution towers in parallel connection connected in series.  Grown crystals may be crushed and screened or reduced in size by partially dissolving them in a solvent in order to provide seed crystals.
