Abstract: 1396381 Solution mining INTERNATIONAL SALT CO 27 March 1972 [29 March 1971] 14306/72 Heading E1F [Also in Division F4]  A method of mining salt from the sides only of a cavity 10 and for providing for underground storage of industrial fluids. The method involves adding to the cavity in any suitable order a salt solvent, e.g. water or brine and a low heat conductivity liquid, e.g. a liquified industrial fluid, a salt solvent, e.g. water or brine and a fluid of low heat conductivity and of a specific gravity less than the solvent and the liquid, which like the fluid will not attack the salt, whereby the . cavity is completely filled by a bottom layer of liquid, an intermediate layer of solvent, and an upper layer of fluid, and then adding further solvent to the cavity whilst removing solvent of a higher salt concentration from the cavity so that salt is only dissolved from the sides of the cavity in the salt deposit. The liquid may be liquid chlorine, carbon tetrachloride, carbon bisulphide, or the like. The fluid may be air, nitrogen, freon, krypton, zenon, neon, argon, benzine or light hydrocarbons. The salt deposit may be rock salt, sodium borate, potash or the like. The cavity as it is being enlarged or on reaching a final size may be used for storing industrial fluids such as specified above.

Title: Manufacture of new products applicable for making dyestuff preparations and of new dyestuff preparations made therewith
IPC: D06P1/62
Filed: 1927-05-27
Abstract: 271,898. Soc. of Chemical Industry in Basle. May 29, 1926, [Convention date]. Sulphonic acids; dye preparations.-The distillation residues from benzaldehyde are sulphonated by treating them with an agent such as sulphuric acid, fuming sulphuric acid or chlorsulphonic acid; the products are used for making dyestuff preparations in which the dyestuff is present in finely-divided form. The preparations may be used in the form of pastes, or they may be dried by evaporation, with or without the addition of another protective colloid, e.g. sulphite cellulose lye. Preparations of vat dyestuffs or of dyestuffs having affinity for cellulose esters are particularly useful. In examples, (1) the resinous by-product obtained in the rectification of benzaldehyde is sulphonated with fuming sulphuric acid and the product converted into the sodium salt, (2) the dyestuff from diazotized p-nitraniline and cresidine is pasted with a solution of the product made according to example 1, the resulting paste may be dried in a vacuum and powdered, either the paste or powder being suitable for preparing a dye-bath for acetate silk; pastes may be similarly produced from pyrazolone-azo dyes, anthraquinone derivatives or indophenols, (3) a flavanthrone paste is stirred with the sodium salt of the product obtained according to example 1, the paste becomes more fluid and passes into a vat, dyeing cotton in fast yellow tints, in presence of alkaline hydrosulphite solution; by drying the paste with sulphite cellulose lye, solid preparations are obtained which are particularly useful in cotton printing, and (4) a paste from 1:4:5: 8-tetra-aminoanthraquinone and the product made according to example 1 is stirred with soap solution and diluted with water to form a bath in which acetate silk is dyed a vivid blue; dye-baths may be similarly made from azo dyestuffs or indophenols. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the manufacture of sulphonation products from the distillation residues of turpentine and their use in making dyestuff preparations. According to one example, colophony is sulphonated by warming with sulphuric acid and the product converted into the sodium salt; similar products may be obtained from resin oil (the distillation products of colophony). In another example the product obtained from colophony is used for pasting the indophenol from diphenylamine and nitrosophenol; azo or anthraquinone dyes may be similarly treated. This subject-matter does not appear in the Specification as accepted.

Title: Hydrualic control system for a bucket loader
IPC: E02F3/43
Filed: 1971-05-12
Abstract: 1334581 Bucket loaders SPERRY RAND CORP 12 May 1971 [12 June 1970] 14413/71 Heading E1F A bucket loader includes an automatic bucket curl valve and means for disabling the automatic valve, when a manual curl valve is operated, by preventing the flow of fluid to the actuator of the automatic valve. When bucket 12 is crowded and boom 14 is lifted the weight of material in the bucket develops a pressure in line 18 which is passed via line 100 to adjustable relief valve 116. When valve 116 opens the pressure is passed via lines 104, 66 to the spool of valve 50 to open the valve. The opening of the valve 50 actuates jack 32, via lines 54, 56, to curl bucket 12. When manual valve 38 is operated to curl bucket 12, lines 102, 106 impose the pressure difference across check valve 40 on the shuttle of valve 114 to close line 104 and thereby close valve 50. Line 78 connects lift jack 16 to the spool of valve 50, so that the pressure generated in jack 16 during bucket lowering keeps valve 50 closed.
