摘要： 2-Mercapto-6-methyldihydropyrimidines, of the general formula (or tautomeric forms thereof), wherein R represents alkyl and X an aryl, arylamino or substituted aryl radical, are manufactured by reacting an aromatic primary amine or a monoarylhydrazine with ammonium thiocyanate and a b -hydroxy-b -methyl ketone The reaction is conveniently carried out in aqueous acidic solution, e.g. by adding concentrated aqueous hydrochloric acid slowly to a mixture of the other reagents containing water and the raising to whole to boiling point for a few minutes. Starting materials specified are: aniline, o- and p-chloraniline, p-nitraniline, 2 : 5-dichloraniline, p-aminophenol, anthranilic acid, p-aminobenzoic acid, sulphanilamide, p-phenylenediamine, benzidine, b -naphthylamine, p-toluidine, dehydrothio-p-toluidine and phenylhydrazine; diacetone alcohol and 5-hydroxy-5-methyl-3-heptanone. Examples describe the interaction of certain of these compounds, the diamines being stated to yield bis-pyrimidino compounds. The Provisional Specification comprises also the manufacture of compounds of the general formula above wheren, when R represents methyl, X may also represent hydrogen, an aliphatic or alicyclic radical, a free amino group, or a substituted amino group other than arylamino, by replacing the aromatic primary amine or arylhydrazine by other amines, including ammonia, or hydrazines, including hydrazine itself, or, when X=H, by simply heating ammonium thiocyanate with excess of diacetone alcohol.

摘要： Extreme pressure lubricants comprise mineral oils having incorporated therein sulphurized esters obtained by reacting sulphur with unsaturated esters of mono- or di-hydric aliphatic alcohols with naturally occurring fatty acids having from 16 to 24 carbon atoms, the alcohol and/or acid radicals being unsaturated, in the presence of a secondary amine of the aliphatic, alicyclic or reduced heterocyclic series (see Group IV (b)). Examples describe as additives the sulphurized glycol, allyl and oleyl esters of rape seed acids, sperm oil and triethylene glycol and ethyl esters of soya fatty acids, dicyclohexylamine being used as activator in their preparation. Specification 588,353 is referred to. The Provisional Specification describes as additives, the products obtained by reacting sulphur with the mono- or di-hydric alcohol esters of naturally-occurring unsaturated aliphatic acids having 18 to 24 carbon atoms, preferably in presence of the above-mentioned activators.ALSO:Sulphurized esters are prepared by reacting sulphur with unsaturated esters of mono- or di-hydric aliphatic alcohols with the naturally occurring fatty acids containing 16 to 24 carbon atoms, in the presence of secondary amines of the aliphatic alicyclic or reduced heterocyclic series as activators. The alcohols and/or the acids may be unsaturated. At least 12 1/2 per cent by weight of sulphur may be used. The reaction is generally carried out at from 130 DEG to 180 DEG C. The products are extreme pressure additives for use in lubricating oils (see Group III) and have the same properties as the sulphurised glycerides described in Specification 588,353, [Group III]. In examples, sulphurised products are prepared from the glycol, allyl and oleyl esters of rape seed acids, sperm oil, and the triethylene glycol and ethyl esters of soya fatty acids, using dicyclohexylamine as the activator in each case. According to the Provisional Specification, liquid sulphurized products may be prepared by reacting sulphur with mono- and di-hydric alcohol esters of naturally occurring unsaturated aliphatic acids having 18-24 carbon atoms, preferably in presence of the above-mentioned applicators.

摘要： 149,429. Roberts & Co., C., and Greaves, J. R. May 13, 1919. Angular bending; making chains.-In apparatus for making links, shackles, rings, &c., a bar 3 is placed in the transverse slot of a table 2, which is moved by an hydraulic plunger 15 or otherwise towards two pivoted jaws 4. which are actuated by the table to bend the bar round the die. 4 . The jaws are connected by a toggle 6, the pin 7 of which engages a slot 9, and when the movement of the table causes the end of the slot to engage the pin 7 the jaws 4 are turned on their pivots to close on the work. The reverse movement of the table opens the jaws 4 by means of inclines 2 or by an opposite end of the slot 9 engaging the pin 7, and then causes a fixed stop 14 to press the scarfed ends of the bar against the die 4 . The link is then removed for welding. The table has a longitudinal recess 11 to receive a finished link through which the bar 3 is inserted; stops for positioning the bar may be provided.
