Title: New glucoside extract of meadow saffron and process for preparing same
IPC: C07H15/248
Filed: 1952-11-28
Abstract: The invention comprises a new crystalline glucoside from meadow saffron named colchicoside, and the preparation thereof by (a) extracting all the other active constituents from meadow saffron by means of a first solvent capable of dissolving them but not colchicoside (a lower (1-3C) halogenated aliphatic hydrocarbon), and then extracting colchicoside from the residue by means of a second solvent capable of dissolving it (water, a lower (1-5C) alcohol, or a mixture of a lower alcohol with water or with a lower halogenated aliphatic hydrocarbon), or (b) extracting meadow saffron with a solvent known to be capable of dissolving all the active constituents (e.g. one of the "second solvents" of (a)), and then exhausting with a lower halogenated hydrocarbon the resulting liquid extract, or the dry residue obtained by evaporating the solvent therefrom (with or without addition of an inert material), or a solution obtained by evaporating the liquid extract and redissolving the residue.  The exhaustion of the liquid extract in (b) may also be preceded by the addition of a mineral salt soluble therein to act as a salting out agent.  In examples: (1) pulverized meadow saffron is degreased and then extracted first with chloroform and then with water, the crude colchicoside obtained by evaporation of the water being recrystallized from alcohol; (2) an aqueous, dilute alcoholic or alcoholic extract of meadow saffron seeds is extracted with chloroform, and colchicoside is then extracted from the residue with a 4 : 1 mixture of chloroform and ethanol; (3) the extract of (2) is dried and the residue, mixed with alumina, is exhausted with trichloroethylene and the residue extracted with a 4 : 1 mixture of trichloroethylene and isopropanol; (4) powdered and degreased meadow saffron is extracted with a mixture of alcohol (or other lower alcohol) and chloroform (or tetrachloroethane or trichloroethylene), and the extract is dissolved in water and exhausted with chloroform and then purified with active carbon and evaporated to dryness and the residue recrystallized; (5) a dilute alcoholic extract of meadow saffron seeds is saturated with ammonium sulphate and extracted with tetrachloroethane, and the extract is then extracted with water, the aqueous extract purified with active carbon and evaporated to dryness, and the residue crystallized from alcohol.

Filed: 1931-10-31
Abstract: 376,596. Universal joints. HADDAN, R., 31, Bedford Street, Strand, London.- (Universal Products Co., Inc. ; 6455, Kingsley Avenue, Detroit, Michigan, U.S.A.) Oct. 31, 1931, No. 30244. [Class 80 (ii).] In a universal joint of the kind comprising a ball head 2a on one shaft, carrying a pin 2b on which are balls 3 or rollers engaging diametrically opposite cylindrical recesses in a casing 4 and wherein there is a guide or protector 1 between the ball head 2a and a central cylindrical recess in the casing, such as that described in Specification 225,783, [Class 80 (ii), Gearing, Variable-speed &c.], the guide 1 has two diametrically opposite part - spherical recesses which retain it in engagement with the ball and is longitudinally divided. The guide is of cast, wrought, pressed, or rod metal and its halves are held together by the end 11 of a spring 7 or by a clip engaging a grooved flange 1c formed at the end of the guide. The halves of the guide are not dependent on the spring 7 to retain them on the ball head and the guide prevents the transmission of rocking movement of the ball head to the spring which is thus maintained axial. Open ended slots 1e accommodate the joint pin 2b. In a simpler construction, not intended to permit relative axial movement of the coupled shafts, the casing 4 is integral with the splined shaft member 5 and the spring 7 is omitted.
