Title: Sulphur-containing derivatives of high molecular weight paraffinic hydrocarbons and lubricating compositions containing such derivatives
Filed: 1954-01-29
Abstract: Sulphur-containing compounds, in which hydrocarbon radicals are linked together by one or more sulphur atoms are prepared by reacting a halogenated paraffinic hydrocarbon containing at least 15 carbon atoms in the molecule in alcoholic solution with an inorganic metal sulphide under a pressure of between 150 and 500 p.s.i.g. and at a temperature of between 125 DEG  and 165 DEG  C. in the presence of an amount of water such that the mol. ratio of water to the inorganic metal sulphide is between 10 : 1 and 25 : 1.  A hydrocarbon solvent and elementary sulphur may also be present. Suitably, the reactants are halogenated paraffins containing 15-50 carbon atoms and 15-50 per cent by weight of halogen, especially chlorine, and the alkali metal mono- and di-sulphides. The alcoholic solvents include ethanol and its homologues up to isoamyl alcohol.  The normally liquid paraffins and aromatic hydrocarbons are suitable hydrocarbon solvents. Examples describe the preparation of wax mono- and disulphide type compounds from sodium mono- or di-sulphide and chlorinated paraffins of chlorine content about 30 per cent and molar weight 368 wherein the general procedure comprises heating an alcoholic solution of the halogenated paraffin with an aqueous solution of the metal sulphide in an autoclave until substantial interaction occurs, whereupon the product is worked up.  The products which have a low chlorine content, are used as additives for lubricating oils, greases and hydraulic fluids (see Group III).  U.S.A. Specification 2,346,157 is referred to.ALSO:Lubricating oil compositions comprise derivatives of paraffinic hydrocarbons having at least 15 carbon atoms wherein hydrocarbon radicals are linked together by one or more sulphur atoms, the additives being prepared by reacting a halogenated paraffin of at least 15 carbon atoms in alcoholic solution with an inorganic metal sulphide in the presence of water in specified manner (see Group IV(b)).  The additives improve resistance to oxidation and decomposition and reduce corrosivity and examples illustrate these effects using a mineral lubricating oil and an additive containing 21.9 per cent sulphur and 3.0 per cent chlorine prepared by reacting sodium sulphide with a halogenated paraffin containing 30 per cent chlorine and having a M.W. of 368.  U.S.A. Specification 2,346,157 is referred to.

IPC: F42B22/04
Filed: 1919-02-05
Abstract: 123,089. Duffie, J. J. Feb. 8, 1918, [Convention date]. Sounds, controlling and actuating apparatus by. -Consists of apparatus for automatically firing an explosive mine when a vessel approaches within a given distance, comprising a sound-responsive device which is adapted after it has been in operation for a predetermined continuous period to effect the action of the firing-device. The mine is preferably fired by electric means controlled by a thermal switch, but a mechanical connexion between the sound-responsive device and the firing- means may be employed, and where an electric firing-device is used, a circuit-closer operating in the desired manner may be provided. The apparatus shown comprises a microphone 2, Fig. 1, arranged on the mine A and connected in a battery-circuit including the primary 4 of an induction coil. The secondary winding 8 of the coil is connected to an electro-magnet 9, Fig. 2, mounted beneath a diaphragm 10 which carries a contact 11. This contact co-acts with a pivoted spring- regulated contact 12 so as normally to close a circuit through an electro-magnet 19, the armature of which is on a lever 23 carrying a contact 25 adapted to co-act with a fixed contact 27. When sound waves fall on the microphone 2, pulsations of current are thereby set up which cause the contacts 11, 12 to chatter. The spring-controlled armature-lever 23 is thus set in vibration, and a circuit comprising leads 35, 39 is thus intermittingly closed through contacts 25, 27 ; or the parts may be so adjusted that, during the operation of the microphone, the contacts 25, 27 are held together. The leads 35, 39 are in a circuit, shown in Fig. 3, comprising a variable resistance 37 and a thermal switch 28. This switch comprises a bimetallic or like coil which, when heated by the passage of current through a surrounding resistance-coil 28<1>, causes a contact-carrying hand 31 to approach and, after a predetermined movement, touch an adjustable contact-hand 33'. When this occurs, owing to the operation of the microphone 2 for a given time and the consequent passage of a current through the heating-coil 28<1> for a sufficient period, a current will flow through the firing-device of the mine, causing explosion. The firing- device shown is a heating-coil 42 connected to the battery 38 and to the contact-arm 33<1>.

Abstract: 1380253 Prosapogenins from Ruscus aculedtus INVERNI DELLA BEFFA SpA 21 Jan 1972 [21 Jan 1971] 2874/71 Heading C2U [Also in Division A5] Novel compounds which may be hydrolysed to ruscogenin or neoruscogenin are obtained by subjecting saponins of Ruscus aculeatus L. to partial hydrolysis, in particular enzymatic hydrolysis, resulting in removal of a glycosidic group attached to the 26-carbon atom of the saponin. The compounds are generally isolated in the form of mixtures known as "prosapogenins" which may be hydrolysed to form mixtures of ruscogenin and neoruscogenin. Particular components of certain of the prosapogenins have the formulae wherein R is one of the groups Preferably the hydrolysis is performed by dissolving or suspending the saponins in an aqueous solvent, e.g. water or a mixture of water and alcohol, acetone or dioxan, adding a waterimmiscible solvent e.g. ethyl acetate, treating with a pure #-glycosidase, a mixture of enzymes or an enzyme complex having #-glycosidasic activity, and effecting the hydrolysis at a temperature of 20-60‹ C. and at a pH of 4-8, the prosapogenins being recovered from the water-immiscible solvent. The crude prosapogenins obtained may be used as a raw material for obtaining partially purified prosapogenins, for the preparation of a number of pure prosapogenins and also as a raw material from which the components of the individual prosapogenins may be isolated. The isolated or chromatographically identified prosapogenins are (a) desgluconuscin (prosapogenin R6) which is a mixture of 1-O-[O-α-L-rhamnopyranosyl - (1#2) - α - L - arabinopyranosyl]- spirosta - 5(6),25(27) - diene - 1#,3# - diol (I) and 1 - O - [O - α - L - rhamnopyranosyl - (1#2)- α - L - arabinopyranosyl] - 25R - spirost - 5(6)- ene-1#,3#-diol (II), from which mixture (I) is obtained pure by acetylation of desglucoruscin, separation of the acetyl derivatives of ((I and (II) by crystallization and chromatography, and hydrolysis of the pure acetyl derivative of (I); (b) desglucodesrhamnoruscin (prosapogenin R9) which is identical with desglucoruscin but with a residue of rhamnose absent, and which may be formed by heating desglucoruscin with acetic acid and separated into its pure components in the same manner as (I) and (II) are separated; (c) ruscin (prosapogenin R4), which is a mixture of 1 - O - [O - # - D - glucopyranosyl - (1#3). O - α - L - rhamnopyranosyl - (1#2) - α - L- arabinopyranosyl] - spirosta - 5(6),25(27) - diene- 1#,3# - diol(V) and the corresponding 25R- spirost-5(6)-ene-1#,3#-diol (VI), which may again be separated in the same way as (I) and (II) are separated; and (d) four further prosapogenins designated R5, R3, R7 and R8. The novel compounds are useful in the treatment and prevention of circulatory disorders (see Heading A5B).
