A 13# - alkyl - 17# - ethyl - 11 - oxygenatedgona - 1,3,5(10) - trien - 17# - ol or a 13#- alkyl - 17 - ethylidene - 11 - oxygenated gonane having further unsaturation in ring A is prepared by (a) hydroborating a 3-hydroxy or protected hydroxy 13#-alkyl-17#-ethyl-gona- 1,3,5(10),9(11) - tetraen - 17# - ol to give a corresponding 13# - alkyl - 17# - ethylgona - 1,- 3,5(10)-trien-11,17#-diol, if desired protecting the generated 11-hydroxy group by conversion to an 11-oxo group or a protected hydroxy or oxo group and if desired dehydrating the 11- protected compound to give a 13#-alkyl-11- oxygenated - 17 - ethylidene - gona - 1,3,5(10)- triene. In these products, a protecting group may be removed, an 11α-hydroxy group epimerized or oxidized, a 3-alkoxy-gona-1,3,5(10)- triene Birch reduced and hydrolysed to give a 4-en-3-one or 5(10)-en-3-one, a 3-oxo group protected, an 11-hydroxy group re-protected, or a 3-alkoxy group formed from a 3-hydroxy group or a 3-protected hydroxy group other than a 3-alkoxy group. Novel products have the formula where Y is OH or protected OH and ring A is aromatic or Y is etherified OH and there is a 2,5(10)- diene system, or Y is protected oxo and there is a 4-, 5(6)- or 5(10)-double bond with or without a 2- or 3-double bond, or Y is oxo and there is a 4- or 5(10)-double bond, and (a) R<SP>1</SP> is alkyl, R<SP>2</SP> and R<SP>3</SP> together are ethylidene, and W is α- or #-OH or protected OH or oxo or protected oxo; or (b) R<SP>1</SP> is alkyl other than CH 3 , R<SP>2</SP> is OH or protected OH, R<SP>3</SP> is ethyl, and W is as in (a); or (c) R<SP>1</SP> is CH 3 , R<SP>2</SP> and R<SP>3</SP> are as in (b), and W is α- or #-alkoxy. Fig. 1 illustrates the invention in its preferred embodiments. The protecting groups are those known in the art which are readily convertible, e.g. by hydrolysis, to free hydroxy or oxo groups. In the process the steroid nucleus can contain further substituents other than those specified. The 13#-enantiomers may be in resolved or racemate form according as to whether the starting materials are resolved or racemic. The novel 13#-alkyl-11-oxygenated-gonenes have steroid hormone and anti-microbiological activity and they may be made up into pharmaceutical compositions with suitable carriers.

Title: Polymers of acrylamide and other monomers
IPC: C08F2/22
Filed: 1961-08-01
Abstract: Water-soluble ethylenically unsaturated compounds are polymerized by a process in which, either the compound or compounds are mixed with water and the mixture is emulsified in an organic solvent containing a surface-active agent to form a water-in-oil emulsion, or the water is emulsified in the organic solvent and the compound or compounds are mixed with the emulsion, the amount of compound or compounds being such that, at 30 DEG  C., the aqueous mixture would be at least saturated with the compound or compounds; thereafter the monomeric compound or compounds are polymerized in the presence of a polymerization catalyst until a polymeric material in bead form dispersed in an organic solvent is formed.  The process is particularly applicable to the formation of homopolymers of acrylamide and copolymers of acrylamide with acrylic acid or dimethylaminoethyl methacrylate.  At the end of the polymerization reaction 0.1-5% of alkali hydroxide, based on the weight of polymer, may be added and the surface of the polymer beads thereby hydrolysed at elevated temperature. The preferred catalyst is a redox mixture of cerium ammonium sulphite and sodium sulphate containing an amount of sulphuric acid.
Patent GB-654164-A (GB)
Title: Improvements in colour photographic reproduction processes employing dyed reliefs
Inventor: GRESHAM DONALD CHARLES
IPC: G03C7/25
Filed: 1947-10-17
Abstract: 654,164. Photographic colour reproduction process. KODAK, Ltd. Oct. 17, 1947, No. 27894. [Class 98 (ii)] In procedure which includes the making of colour separation reliefs of an object or image, correction for unwanted absorption of colour by a dye used on one of the reliefs is obtained by removing a part of the dye from such dyed relief by bringing it into registered contact with a laterally reversed relief which is a record of the colour which is unwantedly absorbed. Thus, for example, undesired absorption of blue light by magenta dye used on a green record relief may be corrected by pressing an undyed reversed blue record relief on to the magenta dyed green relief to remove part of the magenta dye therefrom ; and, similarly, correction in respect of either one or two unwanted absorptions may be made in the case of any of the dyes used. The reliefs so treated may be superimposed to make a colour picture or the dye remaining on them may be transferred as to mordanted gelatin coated plates to produce printed pictures. Dye removed by the reversed reliefs may be washed therefrom, to permit re-use or the method may be operated as by dyeing the reversed relief instead of the relief with which it is contacted. The reliefs used to remove dye may be made by a lower exposure and preferably also with greater contrast, whereby tone correction may be combined with colour correction. Any existing colour separation negatives of normal contrast may be used to print the positives required for the process and it is not necessary to know in advance that colour correction is to be effected. Colour-corrected screen separation negatives for use in half-tone block or photolitho plate making may be made from a set as of three positive reliefs treated as by the method of the invention, but for this purpose it is sufficient to dye all the positive reliefs in yellow dye since the operative factor is only the dye-density of the treated reliefs to blue light when screen negatives are made on bluesensitive plates. The three laterally reversed negatives carrying yellow dye resulting from the process may be used to form a screen negative suitable for making a black printer. Specifications 553,196, 553,229 and 553,230 are referred to.

Title: A method of producing protein of low fat content from marine sources
IPC: A23J1/04
Filed: 1957-09-04
Abstract: Protein of low fat content from marine sources is produced by comminuting fish or whale protein while simultaneously treating it with a solvent mixture having a fat-dissolving component and a water-miscible component for from 1 to 120 minutes at a temperature of from 5 DEG  to 60 DEG  C. at a pressure of from 1 to 5 atmospheres, separating the resulting liquid from the solids and washing and drying the solids.  The major proportion of the oil may be removed from the protein, e.g. by boiling, centrifuging and/or pressing, prior to comminuting and treating with the solvent mixture. The solvent mixture may be a mixture of ethanol with acetone, trichloroethylene, toluene, carbon tetrachloride, benzene, or methylene chloride, methylene chloride and butanol, trichloroethylene and isopropnaol, or a mixture of benzene, perchloroethylene and isopropanol.  The mixture may contain methylene chloride and ethanol in a volume ratio of 2 : 1.
