No. 19507.—23rd May, 1905.—JOSEPH PRICE, of No. 17, Devonshire Square, London, England, Chemist. Improvements in processes for manufacturing nitrate, nitrite, or sulpho nitrate or nitrite of lime, soda, or potash.

Extract from Specification.—First, I separate the nitrogen and oxygen of atmospheric air by my special apparatus for the purpose, described in my specification of Patent No. 14213 of 1903, or by any other suitable apparatus or contrivances, and then collect the said gases in chambers or gasometers, from whence they are discharged under pressure in combining proportions into a closed vessel, or, and as preferred, into a series of vessels, containing a solution of caustic soda or caustic potash or caustic lime, the latter being chiefly in suspension, in which solution has been introduced either gypsum (sulphate of lime) or carbon, the latter (if employed) preferably being in the form of coke or charcoal. I may, if desirable, employ both gypsum and carbon or any other suitable converting agent or “carrying” medium such as spongy platinum, whose influence would facilitate the combination of the gases with the basic substance. When this said combination has been effected the saturated solution is drawn off, evaporated, and the resulting nitrate salts crystallized out or evaporated to dryness, the “carrying” mediums or converting agents before referred to being retained for use over and over again.
[NOTE.—The above extract from the specification is inserted in place of the claims.]
