Abstract: 1,206,006. Cyanuric acid. SHIKOKU KASEI KOGYO CO. Ltd. 25 Jan., 1968, No. 4068/68. Addition to 1,076,934. Heading C1A. Cyanuric acid is produced by heating urea and/or biuret below 400‹ C. in a reaction vessel on the surface of a molten metal having a melting-point not exceeding 350‹ C., between two horizontal rollers, each rotating in either direction, partly immersed in the molten metal, until a solid mass is formed which is further heated on said surface or subsequently to obtain a solid product containing cyanuric acid. The preferred temperature is 230-350‹ C. Metals specified are Sn, Bi, Pb and alloys of Sn, Sb and Pb, and of Bi, Cd, Pb and Sn. Preferably the starting material is urea which is delivered on to the melt's surface R. The rollers 4 become coated with a film of the molten metal and prevent adhesion of the reaction mixture to the tank. In the preferred apparatus, illustrated in Fig. 2, molten urea is delivered from a storage tank 5 both on to the surface of the metal between the rollers and to troughs 7 whence it overflows on to the side areas of the surface and moves towards the beginning of the reaction surface R. The rollers 4 may be formed with helical screws to deliver the reaction mixture from one end of the vessel. The solid is continuously withdrawn from the vessel by rollers 8 and granulated by crusher 9, and heated in a heating tank. By-products are hydrolysed by heating in aqueous mineral acid. The reaction vessel is sealed so as to simplify the collection of ammonia evolved in the reaction, and so as to simplify the recovery of the urea entrained in the ammonia, preferably by condensation at 100-130‹ C.

Patent GB-818175-A (GB)
Title: Improvements in or relating to process of treating meat
IPC: A23B4/20
Filed: 1956-02-14
Abstract: Meat is cured by treating it with nitric oxide in an amount and for a time sufficient to impart to the meat a cured colour but insufficient to produce a green colour in the meat.  By cured colour is meant the colour of meat obtained by treatment under usual conditions with curing salts such as sodium nitrate and sodium nitrite.  The process is applicable to both fresh and denatured, i.e. cooked, meats and the nitric oxide, which may be in aqueous solution, in gaseous admixture with nitrogen, or dissolved in ice, is used preferably in the absence of air.  Quick curing of chunk meats, e.g. hams, bacon slabs, and briskets can be effected by pumping them with a pickling solution, e.g. of salt and sugar, saturated with nitric oxide.  Sausages such as bologna, frankfurters, and meat loaf items, are cured by adding a saturated solution of nitric oxide during the chopping operation employed for the preparation of the meat and water emulsion, or by incorporating the gas solution in the emulsion in a vacuum mixer. In one example the water used in the preparation of a sausage emulsion is derived from a saturated solution of nitric oxide. Gaseous nitric oxide can be injected into the emulsion during the chopping operation or subsequently, e.g. at the stuffing horn. Examples describe the curing of a bologna emulsion and of a dry sausage, e.g. Genoa sausage, by addition of a nitric oxide-nitrogen atmosphere to the emulsion in a vacuum mixer, and by grinding the meat into a nitric oxide-nitrogen atmosphere, respectively.  One example describes the preparation of a bologna emulsion by chopping the meat with ice containing nitric oxide. The meat being emulsified in water from the melted ice.  Another example describes the production of a cured colour by treating cooked beef with an atmosphere of nitric oxide and nitrogen with and without the addition of ascorbic acid.
