Title: Production of alpha-hydroxy-gamma-mercapto-carboxylic acids and salts thereof and compositions containing the same
IPC: A23K1/16
Filed: 1951-10-24
Abstract: a  - Hydroxy - g  - alkylmercapto - butyric acids are made by heating an amide of formula <FORM:0722024/IV (b)/1> where R is H or Me and R1 is H or an alkyl group of 1-12 carbon atoms, in a solution containing 5 to 40 per cent by weight of mineral acid to a temperature at above 60 DEG  C. and preferably from 80 DEG  C. to the boiling-point of the solution.  Their ammonium salts may be formed by the addition of an alkaline earth metal hydroxide or carbonate, e.g. calcium hydroxide, to the reaction mixture to liberate ammonia from the ammonium salt of the mineral acid, e.g. ammonium sulphate, formed in the reaction, the ammonia then combining with the mercapto acid.  Excess alkaline earth metal hydroxide yields the alkaline earth metal salt or a mixture of this salt with the ammonium salt.  The acids (excluding the methyl mercapto butyric acid) and their ammonium, calcium, strontium, barium and magnesium salts are claimed as new compounds and the latter salts of the methyl-mercapto-acid are used in poultry or animal feeds (see Group I).  Hydrolysis may be effected in the presence of inert organic diluents, e.g. carbon tetrachloride.  Aqueous hydrolysis is preferred.  In examples: (1) and (2) a -hydroxy-g -methyl-mercapto-butyramide is hydrolysed with sulphuric acid to the free mercapto acid and converted to mixtures of its calcium and ammonium salts by treatment with calcium carbonate or hydride, and in (2) the zinc salt of the acid is also prepared for identification purposes.  The a  - hydroxy - g  - alkylmercapto - butyramides are made by the hydrolysis of the corresponding nitriles, c.f. Specification 722,087.ALSO:Poultry or animal feeds deficient in methionine promote the growth of poultry and four-legged non-ruminants e.g. swine, cats and dogs, when fortified with an ammonium, calcium, barium, strontium or magnesium salt of a -hydroxy-g -methylmercaptobutyric acid or mixtures thereof.  Amounts of about 0.1-0.5 per cent. by weight of the feed are specified for poultry.  Mixtures of the ammonium and calcium salts are preferred and example (3) illustrates the rapid growth of chicks fed on a basal diet containing protein, carbohydrates, vitamins and minerals and 0.2 per cent. of a mixture of about 3 parts of the calcium to one part of the ammonium salt.  For the preparation of the salts (see Group IV (b)).

Filed: 1948-11-04
Abstract: 701,521. Sheep shears. DEHN, S. G. (Sun beam Corporation). Nov. 4, 1948, No. 25049/50. Divided out of 701,501. Class 131 In a shearing clipper comprising a handle assembly with a cutter movable back and forth across a comb by means of an oscillation fork pivotally mounted on the handle assembly, a pin being interposed between the fork and an abutment means on the handle assembly to urge the cutter into shearing engagement with the comb, the angle of the pin with respect to the longitudinal axis of the handle assembly is approximately 48 degrees and the abutment means is adjustable longitudinally of the pin for control of the pressure of the pin against the fork. As shown, the clipper comprises a handle assembly 11 which includes a head 12 to which a comb 13 is secured, a cutter 14 oscillated across the comb by driving means 16 and means 18 for adjusting the tension between the cutter 14 and comb 13. The tension means 18 is described in Specification 701,520 and includes a tension pin 101 formed at its lower end with a rounded surface 102 received in a socket 103 at the rear end of a fork 27 and formed at its upper end with a bearing surface 104 seated in a tension cup abutment means 106 telescoped into the upper end of a bushing 107 which is threaded into an inclined sleeve 108 forming part of the head 12. Adjustment of a screwed cap 109 relatively to the bushing 107 varies the pressure of a pin 111 on the tension pin cup 106 and hence the pressure between the cutter 14 and comb 13. The tension pin 101 is disposed at the relatively small angle of approximately 48 degrees to the centre line of the tubular handle so that the bearing socket 103 may be positioned closer to the cutter 14 than to the pivot post 46 and the force transmitted through the pin 101 is more directly applied to the cutter than to the pivot post, lessening wear on the pivot post, and when the tension between the cutter and comb is increased a greater pressure is applied to the cutter than to the pivot ball 48 for a given adjustment. Decreased angularity of the pin 101 also causes the downward pressure on the cutter 14 to increase towards the ends of the path of movement of the cutter.
