Title: Mycobacteriostatic compositions
Inventor: BROWN JOSEPH PATRICK
IPC: A61K31/155
Filed: 1964-04-22
Abstract: Soaps, liquid soaps and shampoos based on synthetic detergents contain a mycobacteriostat consisting of a compound having linked to a nitrogen atom of a biguanide either a halogen-containing aliphatic oxyphenyl group, the aliphatic oxy group of which has at least 2 carbon atoms, or an aliphatic oxyphenyl group in which the aliphatic substituent is a hydro-carbon substituent containing from 5 to 9 carbon atoms, or a salt of such a compound. Specified biguanides are those of the formula <FORM:1040733/C4-C5/1> where R is the aliphatic group which may be alkyl, alkenyl, cycloalkyl, or aralkyl.  The phenyl nucleus may be further substituted, e.g. with a halogen atom, nitro, amino, aryl, or aliphatic group.  A hydrogen atom in the biguanide residue may also be replaced by, for instance, an aliphatic or aromatic group. The salts may either be acid addition or quaternary ammonium salts.  The synthetic detergent materials in shampoos may be ionic, e.g. alkali metal salt of a sulphonated olive or castor oil, non-ionic, e.g. an ester or ether of a polyethylene glycol, or a mixture of both types.ALSO:Mycobacteriostatic compositions comprise a base that is pharmaceutically acceptable for external human use and as active ingredient less than 1% by wt. of the composition of a compound having linked to a nitrogen atom of a bignamide either a halogen-containing aliphatic oxyphenyl group, the aliphatic oxy group of which has at least 2 carbon atoms, or an aliphatic oxyphenyl group in which the aliphatic substituent is a hydrocarbon substituent containing from 5 to 9 carbon atoms, or a salt of such a compound.  Specified bignamides are those of the formula <FORM:1040733/A5-A6/1> where R is the aliphatic group, which may be alkyl, alkenyl, cycloalkyl, or aralkyl.  The phenyl nucleus may be further substituted e.g. it may contain a halogen atom, a nitro, amino, aryl, or aliphatic group (e.g. one of those specified above with reference to R).  A hydrogen atom in the bignamide residue may also be replaced by, for instance, an aliphatic or aromatic group. The salts may either be acid addition or quaternary ammonium salts.  The compositions may be in the form of ointments i.e. anhydrous solutions or dispersions of the active ingredient in a suitable base e.g. animal, vegetable, or mineral grease such as lard or petroleum jelly, oil e.g. olive, arachis, cottonseed or sesame oil, or wax e.g. beeswax.  The base may be an aqueous emulsion in which case the compositions contain either water-in-oil emulsifying agents such as lanolin or wool alcohols or oil-in-water emulsifying agents such as Emulsifying Wax B.P. Ear drops, medicated cosmetic and toilet preparations e.g. hand or body lotions, lipsticks, talcum powders, soaps, liquid soaps and shampoos based on synthetic detergents, may be other forms of the mycobacteriostatic compositions.

Abstract: 399,937. Steam superheaters. BOULTON, P. R., 58, Kewferry Road, Northwood, Middlesex. June 17, 1932, Nos. 17236 and 21215. [Class 123 (iii).] The quantity of water supplied to a superheater 6 is controlled in accordance with the difference in pressure between the inlet and outlet steam and the temperature of the outlet steam. The superheater may comprise initial and final stages 2, 3 separated by a desuperheater 6 of spray or indirect-contact type. The desuperheater is supplied with feedwater through a pipe 14 fitted with pressure and thermostatically controlled valves 17, 16. Steam generated in the superheater, together with the desuperheated steam when a spray desuperheater is used, is passed through a separator 8 before entering the stage 3. If an indirect-contact desuperheater is used, only the steam generated therein passes through the separator and this steam may then enter the main steam run directly. The outlet from stage 2 may be directly connected to the inlet of stage 3 through a byepass valve under the control of thermostat 15. When starting up, the main stop valve 37 and blow down valve 38 are closed and the steam generated passes through valve 34 to a direct contact condenser 30 arranged in the feedwater supply. The superheater and separator are connected to the boiler or a storage vessel by drains 11, 13.

Patent GB-576015-A (GB)
Title: Process for the preparation of tetramethylenediamine
IPC: C07C209/48
Filed: 1944-09-11
Abstract: In a process for the preparation of tetramethylene diamine by the hydrogenation of succinonitrile, the hydrogenation is carried out in the presence of at least 7.5 per cent of a hydrogenation catalyst, based on the weight of succinonitrile present, at a pressure above 200 atmospheres, at a temperature between 25 DEG  and 250 DEG  C. and in the presence of added ammonia.  Preferably, pressures of between 700 and 1000 atmospheres and temperatures ranging from 80 DEG  to 130 DEG  C. are employed.  The hydrogenation catalyst is preferably one free from alkali metal and alkaline earth metal oxides, carbonates and hydroxides, for example, a nickel alloy skeleton catalyst, copper chromite and nickel or chromium supported on kieselguhr or related material; cobalt catalysts prepared as hereinafter described are highly active for the reaction.  For optimum yields a molar excess of ammonia based on the succinonitrile present should be used, preferably an excess based on a molar basis ranging between 10 : 1 and 60 : 1 of ammonia to succinonitrile, and desirably a ratio between 25 : 1 and 35 : 1.  The process may be operated batch-wise or continuous; in the latter case, the converter employed should be substantially fully charged with catalyst so that the products of the reaction are not in contact with the reactants at reaction temperature for any appreciable time with consequent decomposition. In examples: (1) a mixture of succinonitrile, ammonia and hydrogen are reacted in two silver-lined shaker tubes in the presence of a cobalt catalyst prepared by reduction of cobalt oxide granules by hydrogenation and tetramethylene diamine is recovered by filtration and fractional distillation of the filtrate; (2) the same process is carried out in a continuous manner using a silver-lined vertically positioned converter filled with a cobalt catalyst; (3) the results are given of a series of reactions carried out as in (1) above in a single shaker tube using cobalt or nickel catalysts, in amounts varying between 11 to 21 per cent based on the nitrile.
