Abstract: A resin having at least two dimensions each in excess of one cm. and comprising a three-dimensionally cross-linked polymer matrix bonded to cation-exchange groups, is formed by polymerization of a solution mixture of (1) at least one monovinyl aliphatic compound having at least one carboxylic acid group, carboxylic acid anhydride group and/or carboxylic acid ester group; (2) if desired, with at least one monovinyl aryl compound; (3) a polymeric product prepared by the polymerization of (1), or (1) and (2), in an amount of at least 0.1 per cent based on the weight of (1) or (1) and (2) respectively; and (4) at least one polyvinyl aryl and/or polyolefinic compound, the cation-exchange groups being carboxylic acid groups, which are either present as such in the case where the monovinyl aliphatic compound has a carboylic acid group, or are formed by hydrolysis where the monovinyl aliphatic compound has a carboxylic acid ester group, or a carboxylic acid anhydride group.  Specified monovinyl aliphatic compounds are maleic acid or anhydride, acrylic, methacrylic, alpha-chloroacrylic, alpha - bromoacrylic, alpha-phenylacrylic alpha-ethylacrylic, alpha-tolylacrylic, alpha-butylacrylic, alpha-ethylphenylacrylic, alpha-cyclopentylacrylic, alpha-hexylacrylic and alpha-octylacrylic acids, and their methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, octyl, lauryl, octadecyl, benzyl and phenylethyl esters.  Specified monovinylaryl compounds are styrene, alpha-methyl styrene, ar-methylstyrene, ar-dimethylstyrene, ar-ethylvinylstyrene, ar - chlorostyrene, ar - sec - butylstyrene, ar-trimethylstyrene, ar-methylvinylnaphthalene, vinyltoluene, vinylbenzene, vinylxylene and vinylnaphthalene. Specified polyvinyl aryl compounds are divinylbenzene, ar-divinyltoluene, ar-divinylxylene, ar-divinyl chlorobenzene, divinylnaphthalene, ar-divinylethylbenzene, and trivinylbenzene. Specified polyolefinic compounds are butadiene, isoprene, dimethylallyl, dimethylether, dimethylallyl sulphide, divinylether, vinylallyl ether, diallyl maleate, 2-chloroallyl crotonate and ethylene dimethacrylate.  The resin may be prepared by partially polymerizing the monovinyl aliphatic compound, together with any monovinyl aryl compound by bulk or solution polymerization so as to convert 0.1 to 60 per cent to polymer, mixing this solution with the polyvinyl aryl and/or polyolefinic compound, and subjecting this to bulk or solution polymerization and then hydrolysing if necessary. The resin, before hydrolysing, may be formed as a block which is then cut into a sheet, or the sheet may be formed by polymerizing in a vessel facing two facing walls of large surface area with a small clearance in between.  A plasticizer which may be introduced at any stage, and non-polymerizable reinforcing materials may also be present. U.S.A. Specifications 2,340,111, 2,597,437 and 2,471,818 are referred to.

Title: Water heating system
IPC: F24D3/08
Filed: 1961-08-15
Abstract: 935,873. Central heating and hot water supply systems. P. G. TACCHI. July 31, 1962 [Aug. 15, 1961], No. 29360/61. Class 64 (1). A hot-water system comprises a positive acting steam and water-mixing device 32 in which the steam inlet is opened and controlled by the flow of water passing through the device, a hot-water storage tank 29 which receives hot water from the mixing device 32, an outlet 28 from the storage tank communicating with the inlet side of a pump 27 which delivers water to the water inlet of the mixing device 32, a cold water supply to the system, and a control device 30 for the pump 27 which is responsive to the temperature of water from the outlet 28 of the storage tank 29 and to the temperature of incoming water from the coldwater supply. As shown, the system supplies a radiator 14 and hot-water consuming devices 13, 15, 18 and 19 via a pipe 35, with a return pipe 26 to the pump inlet. A cold tank 10 supplies cold water to devices 15, 18 and 19 by a pipe 24, and to the pump inlet by a pipe 25 which may have a restriction valve 40. When only the radiator 14 is in use, water circulates by natural convection until the temperature sensed by the control device 30, in the form of a thermostat switch, falls below a predetermined level. The pump 27 is then switched on, and the resultant flow rate through the mixer 32 allows steam from a supply 33 to be injected to heat the water. This continues until the thermostat senses a second, higher, predetermined temperature and switches-off the pump 27. When hot water is drawn off from the system, the replacement cold water entering the system, and passing the thermostat 30, causes an immediate activation of the pump 27, and hence of the steam injection in the mixer 32. Any excess flow from the mixer passes to the tank 29 through a pipe 36 incorporating a pressure relief valve 37 which maintains a predetermined pressure in the hot water distribution pipes while the pump 27 is running.

Title: Pharmaceutical compositions comprising progesterone derivatives
Inventor: SPERO GEORGE BASIL
Filed: 1961-08-15
Abstract: 6a -Methyl-9a - fluoro-progesterone derivatives are obtained by the following reaction sequences: 6a -methyl- 11b -hydroxyprogesterone in pyridine is treated with N-bromoacetamide, sulphur dioxide being passed over the surface of the solution, and the methylene chloride soluble fraction of the product is chromatographed on magnesium silicate to give 6a -methyl-4,9(11)-pregnadiene-3,20-dione which, by treatment (a) with perchloric acid and N-bromoacetamide and (b) with sodium sulphite gives 6a -methyl-9a -bromo-11b - hydroxy-4- pregnene- 3,20-dione which, on treatment with anhydrous potassium acetate, gives a reaction product from which 6a -methyl- 9b ,11b - oxido-4-pregnene-3,20-dione may be obtained by extraction with methylene chloride and chromatography on a magnesium silicate column. This compound, on reacting with HF gives a product which, by similar treatment, yields 6a -methyl-9a -fluoro-11b -hydroxy- 4-pregnene-3,20-dione. Treatment of this compound with chromic anhydride gives 6a -methyl-9a -fluoro-11-ketoprogesterone and, by treatment with selenium dioxide gives 6a -methyl-9a -fluoro-11b -hydroxy-1,4- pregnadiene- 3,20-dione which, by treatment with chromic anhydride gives 6a -methyl- 9a -fluoro- 1,4-pregnadiene-3,11,20-trione. Alternatively, 6a -methyl-9a -fluoro-11b -hydroxyprogesterone and 6a -methyl-9a -fluoro-4-pregnene-3,11,20-trione may be converted to 6a -methyl-9a -fluoro- 11b -hydroxy-1,4-pregnadiene-3,20-dione and 1-dehydro-6a -methyl-9a -fluoro-11- ketoprogesterone respectively by adding them (together with 11b ,21-dihydroxy-4,17(20)-pregnadiene-3-one as promoter) to a culture of Septomyxa affinis in a glucosecorn steep liquor medium and separating the desired products by solvent extraction and chromatography.  It is stated that other microorganisms of the genus Septomyxa and species selected from the genera Calonectria, Alternaria, Colletotrichum, Cylindrocarpon, Ophiobolus, Listeria, Corynebacterium, Erysipelothrix, species of the family Tuberculariaceae, Nocardia, Curcurbitaria, Leptosphaeriae, Tricothecium, Mycobacterium, Fusarium and Didymella may be used in place of the above microorganism.ALSO:Pharmaceutical compositions for the local treatment of inflammatory conditions comprise a carrier and a compound of general formula <FORM:0924652/VI/1> wherein R represents a b -hydroxy group or a ketonic oxygen atom and the dotted line in the 1-2 position indicates an optional double bond.
