Title: An improved process for the manufacture of potassium carbonate and sodium carbonate by wet process
IPC: C01D7/02
Filed: 1920-03-02
Abstract: Technically pure potassium carbonate is obtained by a wet process in which potassium bicarbonate is decomposed with nascent potassium sulphide.  The bicarbonate, preferably in granular form, is ultimately mixed with finely ground potassium sulphate and p  barium sulphide, and the resulting mixture is added to boiling water.  The sulphuretted hydrogen produced is eliminated by boiling or by the passage of steam.  The bicarbonate goes into solution with difficulty, but reacts with the nascent potassium sulphide immediately the latter is produced from the barium sulphide.  Barium sulphide is regenerated from the precipitated barium sulphate after its removal from the potassium-carbonate solution, from which crystalline or amorphous potassium carbonate may be prepared.  By using sodium bicarbonate and sodium sulphate in the place of the corresponding potassium salts, technically pure sodium carbonate may be obtained in a similar manner.

Title: A process for the separation of halogenated hydrocarbons and the halogenated hydrocarbons so separated
IPC: C07C17/38
Filed: 1950-03-15
Abstract: Terminally halogenated straight chain hydrocarbons are separated from straight chain hydrocarbons halogenated on non-terminal carbon atoms by contacting a liquid mixture of both with urea at 0-75 DEG  C. allowing the preferential formation of crystalline molecular complexes between urea and terminally halogenated hydrocarbons to take place and separating the complex formed by the urea with the terminally halogenated hydrocarbons from the remaining components of the mixture before complex formation between urea and the non-terminally halogenated hydrocarbons can take place to a comparable extent.  The halogen compounds may be fluorine, chlorine, bromine or iodine derivatives, e.g. 1-chloroheptadecane, 1-chlorohexene-2, 1 : 10-dibromodecane, 1 : 6-dibromohexane and 1 : 7-di-iodoheptane. Preferably, the halo-hydrocarbons are mixed with a solvent, e.g. ketones, alcohols, branched chain hydrocarbons, and treated with the urea in aqueous solution.  The complex is decomposed into its constituents by heat, e.g. in presence of water above 80 DEG C.  In examples: (1) a mixture of 1 : 6-dibromohexane and 4 : 4-dibromohexane are separated by treatment with urea in methyl isobutyl ketone; (2) a gasoline fraction of hydrocarbons is p treated to separate straight chain hydrocarbons which are then chlorinated and the products separated by treatment with an aqueous solution of urea.

Title: Improved protective device for heat exchangers
Inventor: BELL ALAN

Abstract: 806,036. Heat exchangers; steam superheaters. FOSTER WHEELER, Ltd. Feb. 19, 1957 [March 2, 1956], No. 6644/56. Classes 64(3) and 123(3) Relates to a system wherein heat is exchanged in a shell and tube type heat exchanger 2 between two fluids one of which is a liquid or liquid-vapour mixture maintained at a lower pressure than the other fluid by a gas or vapour pressure applied to a free surface of the liquid or liquid-vapour mixture in an expansion tank 8 connected into the lower pressure fluid circuit 4. According to the invention, a safety device 14 is arranged on or near the shell of the heat exchanger 2 and a discharge pipe 16 leads therefrom to the gas or vapour space of the expansion tank 8. Thus, in the event of a fracture in the wall separating the two fluids in the heat exchanger 2, a sudden local rise in pressure in the lower pressure circuit 4 caused by the inrush of higher pressure fluid and which otherwise might take place before the expansion tank valve has opened, is prevented. The safety device 14 may comprise a spring loaded relief valve or a bursting disc. Typical fluid pairs which may be used in the heat exchanger are, high pressure water-low pressure water or steam-and-water, and high pressure steamlow pressure liquid sodium.
