Title: New 5-substituted n-acyl-2-sulpha-pyrimidines
IPC: C07D239/69
Filed: 1963-08-09
Abstract: The invention comprises N1-acyl-sulphapyridmidines of the formula <FORM:1012628/C2/1> wherein R1 is a C1- 3 alkyl group and R2 is a C1- 3 alkyl or alkoxy group and their preparation by (a) hydrolysing, reducing or oxidizing a corresponding compound wherein the primary amino group is protected by an acyl, benzyl or substituted benzyl group or is in the form of a Schiffs base, a urethane or a thiourethane, (b) reducing a corresponding compound wherein the primary amino group is replaced by a nitro group or (c) acylating a corresponding sulpha-pyrimidine with an acylating agent derived from an acid R1.COOH to introduce the residue R1CO on the N1 nitrogen atom.  N4 - Protected - N1 - acyl - sulphapyrimidines wherein the protecting group is for example a carbobenzyloxy group are made by treating the 2-sulphanilamido-pyrimidine with the protective acylating agent such as carbobenzyloxy chloride and further acylating the resulting N4 - acylated - sulphanilamido - pyrimidine with the anhydride of the acid R1COOH.  N4 - Benzylidene - 2 - sulpha - 5 - methylpyrimidine is obtained by the reaction of 2-sulpha-5-methyl-pyrimidine with benzaldehyde.  Pharmaceutical preparations having bacteriostatic action comprise the above sulphonamides of the invention, preferably in admixture with a carrier in a form suitable for parenteral, enteral or local application, e.g. in unit dosage form such as tablets.

Title: Improvements in metallurgy
IPC: C22B3/08
Filed: 1947-12-01
Abstract: A matte containing iron sulphide and at least one other element is digested with aqueous sulphuric acid to produce (1) an aqueous solution of ferrous sulphate substantially free of other elements present in the matte, (2) hydrogen sulphide containing the sulphur combined with iron in the matte, (3) a solid product containing all the remaining sulphides present in the matte; the ferrous sulphate solution is separated from the solid product and is treated, e.g. by evaporation or cooling, to recover solid ferrous sulphate which is decomposed to iron oxide.  The finely divided solid matte, obtained by smelting iron sulphide ore, may be treated at above 25 DEG  C., say 50-70 DEG  C. countercurrent in a series of vats by continuously introducing raw matte into the first vat and 15-20 per cent acid into the last vat of the series to produce a neutral saturated solution of ferrous sulphate and a solid residue of sulphides of cobalt, copper, gold, nickel, platinum, silver, zinc, molybdenum, tin or vanadium. Part of the zinc may be recovered as zinc sulphate at an intermediate stage. The solid ferrous sulphate may be dehydrated in a rotary kiln at 400-450 DEG  C. in a countercurrent of hot gas passed in contact therewith.  The anhydrous product may be heated in a muffle furnace out of contact with air and combustion gases at 480-1300 DEG  C. by hot combustion gases and the waste gases may be passed to the rotary kiln.  The sulphur dioxide in the mixture of sulphur dioxide and trioxide obtained from the muffle furnace may be oxidized to sulphur trioxide and all the sulphur trioxide absorbed in concentrated sulphuric acid to regenerate the acid used in treating the iron sulphide ore.  Specifications 566,375, 656,140, 656,141 and 656,143 are referred to.  The Specification as open to inspection under Sect. 91 comprises also the electrolysis of the ferrous sulphate solution to regenerate sulphuric acid and iron.

Patent GB-655619-A (GB)
Title: Improvements in or relating to the preparation of streptomycin
Filed: 1947-12-08
Abstract: Streptomycin is recovered by direct precipitation from a fermentation broth by reacting the broth, preferably at about pH 5.5, with the dyestuff Naphthol Blue-Black (disodium salt of 8 - amino - 7 - p - nitrophenylazo - 2 - phenylazo-1-naphthol-3 : 6-disulphonic acid), preferably in an amount sufficient to give the maximum precipitation of streptomycin salt for the minimum amount of dye.  The isolated streptomycin-Naphthol Blue-Black salt is converted into other salts of streptomycin by metathetical reaction with (1) a metal salt (e.g. acetate, nitrate, formate, or especially halide, e.g. an alkaline-earth metal halide) in a liquid which is a solvent for both the reacting metal salt and the streptomycin salt produced but a non-solvent for the metal salt of Naphthol Blue-Black, e.g. alcohols, ethers of ethylene glycol, water or mixtures of water with acetone, alcohols or ethers of ethylene glycol); or (2) a salt of an amine (e.g. triethylamine, dimethylaniline, diethylaniline, ethylamine, quinoline, pyridine or ethanolamine) in a liquid which is a solvent for the amine salt of Naphthol Blue-Black but a non-solvent for the streptomycin salt formed (e.g. with an amine citrate, mucate, oxalate, tartrate, sulphonate, phosphate or especially sulphate in the solvents specified in (1) above); or (3) an acid (e.g. sulphuric or hydrochloric acid) in the presence of water and a water-immiscible organic solvent for the acid form of Naphthol Blue-Black (e.g. butyl or amyl alcohol, or glycol ethers such as 2-phenoxy-or 2-benzyloxy-ethanol).  The solution of a streptomycin salt obtained in (1) may be reacted with an amine sulphate to precipitate streptomycin sulphates.  Streptomycin trihydrobromide obtained in (1), (2) or (3) is purified by treating a solution thereof in methanol, evaporating the mixture to the saturation point of the sodium bromide and crystallizing streptomycin trihydrobromide-sodium bromide double salt.  Examples illustrate the various features of the invention, using certain of the reagents specified above.  The Specification as open to inspection under Sect. 91 comprises also the precipitation of the Naphthol Blue-Black salt from partially-purified solutions of streptomycin (e.g. that obtained by adsorbing the streptomycin from a fermentation broth on to activated carbon, eluting with dilute hydrochloric acid, and adjusting the pH to 5.5 with sodium hydroxide), and the preparation of pure streptomycin trihydrohalide-metal halide double salts other than the trihydrobromide-sodium bromide compound (e.g. streptomycin trihydrochloride-calcium, strontium, magnesium or aluminium chloride and trihydrobromide-calcium or strontium bromide) by crystallization from a saturated solution of the metal halide in methanol.  This subject-matter does not appear in the Specification as accepted.

The intersection of a series of conductive strips on a printed circuit board is divided by removal of material into separate areas corresponding to contact areas on one face of a semiconductor wafer constituting e.g. a planar transistor. Typically the circuit board is of resin-impregnated paper, specified synthetic resins or ceramic. In the latter case the strips may be of silver painted, sprayed or vapour deposited on the board and burned in. The intersection is divided by grinding, sandblasting, burning, evaporation by electron beams or etching, and is coated with solder before or after division. In a typical case (Fig. 7) the area 5 is subdivided by sandblasting through a mask 17 mounted in an arm 15 which is then rotated 180 degrees to deliver a wafer at the intersection from magazine 21. A sweated joint is then made. Transistors, diodes and tetrode PNPN planar switches may be mounted in this way.
