    Abstract: Solutions of amino acids having a high cystine content are prepared by hydrolysing keratins with the aid of sulphuric acid and/or hydrochloric acid, mixing the resultant hydrolysate containing free mineral acid with an amount of d-glucose or dextrose corresponding to about 14-16 times the cystine content of the hydrolysate and then neutralizing the free mineral acid. In a modification an amount of starch is added to the hydrolysate which is then heated, whereby the starch is hydrolysed to provide in situ the desired amount of sugar. Neutralization is generally effected with basic alkaline earth metal compounds. The hydrolysate containing sulphuric acid may be neutralized with a keratin hydrolysate prepared using a basic alkaline earth metal compound as hydrolysing agent. Part of the sulphuric acid may be neutralized with a basic alkaline earth metal compound and the remainder with an alkaline earth metal thiocyanate yielding thereby a solution of amino acids, the sugar and thiocyanic acid useful as a disinfectant and as an impregnator for bandages (see Group VI). In typical examples: (1) cleaned hair is hydrolysed by boiling with aqueous hydrochloric acid, treated with charcoal, filtered, boiled with the appropriate amount of starch and then neutralized with ammonia and calcium carbonate; (3) cleaned hair is hydrolysed with aqueous sulphuric acid in presence of charcoal, filtered and boiled with starch; a second quantity of cleaned hair is hydrolysed with aqueous strontium hydroxide and filtered; the two hydrolysates are then mixed and the neutralization of the sulphuric acid completed with strontium carbonate; (4) cleaned hair is hydrolysed with sulphuric acid and the hydrolysate boiled with starch as in (3) and the mixture neutralized with a mixture of strontium carbonate and thiocyanate and filtered.ALSO:Amino acid solutions, suitable for enrichment of inferior nutrition albumen, for producing nutrient media for bacteria and, in conjunction with thiocyanic acid, useful as disinfectants are prepared by hydrolyzing keratins with the aid of sulphuric and/or hydrochloric acid, mixing the resulting hydrolyzate containing free mineral acid with an amount of d-glucose or dextrose corresponding to about 14-16 times the cystine content of the hydrolyzate and then neutralizing the free mineral acid. In a modification, starch is used in place of dextrose or glucose and the solution is heated to form in situ the sugar in required amount. Neutralization is effected with basic alkaline earth metal compounds; thus, the acid hydrolyzate may be mixed with the hydrolyzate obtained by hydrolyzing keratin with the basic alkaline earth metal compound. The thiocyanic acid may be added as such to the neutralized hydrolyzate or added to the partially neutralized hydrolyzate in the form of an alkaline earth metal thiocyanate; the solution, thickened if desired by addition of silica gel, may be used to impregnate bandages. In typical Examples: (1) cleaned hair is hydrolyzed with aqueous hydrochloric acid, the hydrolyzate is then boiled with starch and neutralisation effected with ammonia and calcium carbonate; (2) clean hair is hydrolyzed with aqueous sulphuric acid and boiled with starch, the resulting solution is mixed with a hydrolyzate obtained by boiling with aqueous strontium hydroxide and neutralization of the mixture completed with strontium carbonate; (3) cleaned hair is hydrolyzed with aqueous sulphuric acid, boiled with starch and neutralized with a mixture of strontium carbonate and thiocyanate.

    Abstract: 263,372. Weidner, E. Jan. 18, 1926, [Convention date]. Stream-cutting machines.-Comprises coin-feed apparatus for delivering slices of soap severed from a stick; also means for delivering a strip of paper or fabric. As shown, a pair of soap sticks 31 are supported in containers 4 and are pressed downwardly by a bar 8 threaded on a screwed rod 7 supporting a cutter 42 and connected to a rim 1. The lower edge of the rim is formed with notches adapted to be engaged by a pawl 14 on an arm 13 which is coupled by a coin to an operating-lever 20. Teeth 29 on the upper edge of the rim 1 engage a gear 21 driving rolls 22 , 22 which feed paper 22 from a spool 30 surrounding the rim through an opening 49; the gear 21 also operates a counter 28 through an eccentric and link 27. In operation, a coin inserted into a channel 51 couples the arm 13 to the lever 20 which is moved 180‹ to sever a slice of soap from the stick, such slice dropping through an aperture. The coin drops through a slot 43 into a coin box 38 which is withdrawable from below but is normally retained by a bar 45 secured to the upper part of the casing 33 by a fly-nut 47. Small coins drop through the members 13, 20 into a discharge channel. The lever 20 is returned by a spiral spring and restores the arm 13 through a pin 52.
