Title: Improvements in and relating to the stabilisation of urine
IPC: C05F3/00
Filed: 1952-11-05
Abstract: Nitrogen losses in urine, especially during storage thereof, are prevented by passing a gas containing carbon dioxide into the urine, in the absence of oxidizing agents, so that the pH is adjusted to below 7.  A suitable source of carbon dioxide is flue gas, and the effect is increased if the urine is additionally mixed with a salt having cations forming insoluble carbonates such as water-soluble calcium salts, suitably calcium chloride, nitrate, and primary or secondary phosphate.  The maximum amount of salt added should be about equivalent to the sum of the amount of ammonia formed on decomposition plus the amount of bicarbonate already present.  If phosphates are employed they should preferably be added in such amounts as to give the urine a content of 1 to 2 mols. of ammonia per mol. of phosphoric acid.  Other salts capable of improving the fertilizing properties of the urine such as potassium salts, may be added.  It is preferred to separate the liquid from the precipitate formed when calcium salts are added, to avoid the danger of a reversed reaction.  The urine so treated has a low ammonia pressure and may be stored or spread as fertilizer without danger of nitrogen losses.  To improve storage in tanks the treated urine may be covered by a thin oil film.  U.S.A.  Specification 2,072,154 is referred to.ALSO:Nitrogen losses in urine, especially during storage, are prevented by passing carbon dioxide into the urine, in the absence of oxidizing agents, so that the pH is adjusted to below 7.

Patent GB-225228-A (GB)
Title: A process for the antiseptic digestion of vegetable and animal substances and the obtainment of an antiseptic
Filed: 1924-11-20
Abstract: Fats and fatty oils are obtained from fish by crushing, adding the liquid antiseptic described below, digesting at 30 DEG -45 DEG  C. for 3-20 days and sieving to separate the bone powder.  The separated greases containing incompletely digested nitrogenous residues may be used in tanneries.  The antiseptic is obtained by autolyzing brewers' yeast at a temperature of 36 DEG -44 DEG  C. and separating the liquid portion from the solid portion, the liquid portion constituting the antiseptic.  The autolysis of the yeast is preferably effected without the addition of an antiseptic, and the bitterness may be removed by pressing and centrifuging the yeast as it passes from the brewers' vats, emulsifying in an alkaline carbonate of soda, or ammonia, pressing and washing in dilute hydrochloric acid, and again pressing.  Sodium chloride, up to 60 grams per kilogram of yeast, may be added, and autolysis proceeds from 3 to 20 days.  After autolysis, water is added to facilitate the separation of the liquid antiseptic portion by centrifuging, filtering, pressing &c.  The antiseptic may be concentrated by distilling it over under reduced pressure at a temperature not exceeding 70 DEG  C. which is maintained by a water bath.  The antiseptic is freed from volatile fatty acids by extracting with ether or petroleum ether.  The Specification as open to inspection under Sect. 91 (3) (a) states that distillery yeasts, amylomyces and rhizopus yeasts may be treated, it being necessary to ensure that 5 to 10 per cent of alcohol is present before autolysis, the alcohol being removd at the end of the process.  It is also not necessary to remove the bitterness with carbonate.  The autolyzed yeast is diluted with water, decoloured, e.g. with animal black, Florida earth &c., and the mass is separated into cellulosic residues and a liquid portion.  This subject-matter does not appear in the Specification as accepted.
