Title: Improvements in the treatment of crude cotton oils and of the bye-products resulting from their refinement
IPC: C11B3/02
Filed: 1924-02-06
Abstract: The colouring matter, Gossypol, is separated from cotton oils or from the by-products of their refinement with alkali, by treating the oil or acidified by-product with a metal borate that in aqueous solution is acid to phenol-phthalein, or with a mixture of a metal borate having an alkaline reaction and of a substance repressing alkaline hydrolysis in aqueous solution.  Sodium decaborate alone, and alkali borate or magnesium borate acidified with boric acid or mixed with neutral metal salt, e.g. sodium chloride or with a polyhydric alcohol, e.g. glycerol and mannitol are suitable reagents.ALSO:Cotton oils and the fatty acids in the by-products of their refinement are decolorized by treatment with a metal borate which in aqueous solution is acid to phenol-phthalein, or with a mixture of a metal borate giving an alkaline reaction and of a substance repressing alkaline hydrolysis in aqueous solution.  Sodium decaborate, alone, and alkali borate or magnesium borate acidified with boric acid or mixed with neutral metal salt or with glycerol, mannitol, or other polyhydric alcohol are suitable reagents.  In an example, 1,000 lb. of crude cotton oil are agitated at 60 DEG  C. with a solution of 10 lb. of sodium decaborate and 10 lb. of sodium chloride in 100 lb. of water, or with 100 lb. of an aqueous solution containing 5 lb. of borax, 5 lb. of boric acid, and 10 lb. of sodium chloride or magnesium chloride; after settling the oil is drawn off and the aqueous layer centrifuged.  The purified oils may be further refined with caustic soda.  Soap stock and black grease obtained in the usual refining of cotton oils are either (1) treated with excess of boric acid, preferably at 100 DEG  C., separated from the aqueous layer, if necessary diluted with petroleum, trichlorethylene, or other solvent of oils, and centrifuged; or (2) acidified at 65 DEG  C. or below with sulphuric acid, preferably in presence of sodium sulphite or other reducing agent, separated from the aqueous layer, if necessary diluted with solvent, treated with acid borate solution, and centrifuged. The colouring matter, Gossypol, may be used in place of logwood, cutch, fustic, and the like.

Title: Calendar timepiece
IPC: G04B19/253
Filed: 1967-01-24
Abstract: 1,103,298. Calendar timepieces. EBAUCHES S.A. Jan. 24, 1967 [Feb. 22, 1966], No. 3598/67. Heading G3T. The control mechanism for the date indicator 1 of a calendar timepiece comprises two coaxial wheels 7, 11 rotatable at slightly different speeds and connected together by a spring 14 which becomes stressed as the angular displacement between the wheels increases, the wheel 7 being released once every twenty four hours whereupon its abrupt rotation indexes the date indicator one step forward. Pinions 8 and 13, fastened together on a hub 8a, drive the wheels 7 and 11 respectively, the wheel 7 having more teeth than the wheel 11. The spring 14 is located in a recess (15), Fig. 2 (not shown) in the lower surface of the wheel 11 and the ends 14a, 14b of the spring are bent at right angles to engage sector shaped openings 17 and 18 in the wheels 11 and 7 respectively. Initially the openings 17, 18 are aligned, but as the pinion 13 drives the wheel 11 at one revolution in twenty four hours, the wheel 7 is driven at a slightly slower speed by the pinion 8. The openings 17, 18 are relatively displaced and the spring stressed until a cut away segment 19 of the wheel 7 releases the wheel from its pinion 8. The sudden rotation of the wheel 7 then causes its pin 6 to engage teeth 5 of the date indicator which is advanced by one step. A detent 4 locates the indicator 1 in each position. To conserve power in an electric timepiece, the detent 4 may be raised at the moment of advancing the indicator, the pin 6 remaining in the path of the teeth 5 at the end of the operation to prevent the indicator advancing two teeth at a time.
