Title: Manufacture of a harmless swine-fever serum
IPC: C07K16/12
Filed: 1921-02-26
Abstract: In the preparation of immunizing serum against swine fever the defibrinated blood, or blood serum prepared by ordinary methods, is subjected to the action of an electric current in a three-cell apparatus between suitable diaphragms.  The electro-osmotic treatment is continued until electrolytes have been approximately completely removed and results in the destruction of foreign germs and any swine fever virus present and in the precipitation of corpuscular elements, euglobulin, &c.  The pseudo-globulin and albumin remaining in solution retain the greater part of the immunizing matter and may be used for immunizing or curative treatment with or without the addition of an extract of the precipitated matter made with a weak solution of sodium carbonate or other alkali, or with or without the addition of 0.5 per cent of carbolic acid.  A solution of the immunizing pseudo-globulin without admixture of albumin may be obtained by precipitation with ammonium sulphate or other neutral salt, draining and pressing the precipitate, re-dissolving in distilled water, and removal of remaining ammonium sulphate by treatment in the electroosmotic apparatus.  The solution so obtained may be used as such or may be mixed with the alkaline extract of the matter precipitated by the first treatment of the blood or serum. The various immunizing liquids obtained may be concentrated or dried by evaporation under vacuum at low temperatures.

Patent GB-721823-A (GB)
Title: Improvements relating to a method of producing methane
IPC: C12P5/02
Filed: 1950-03-20
Abstract: Methane is produced by intensively comminuting and homogenizing town garbage to form a mass having a moisture content lower than 60 per cent and which is porous enough to admit of having gases passed therethrough and heating the mass in a closed silo to a temperature at which methane fermentation commences. The comminution and homogenization may be carried out by rotation in drums.  In an example, intensively comminuted and homogenized town garbage is introduced into a closed silo which has a take-off pipe for methane. The silo is heated to about 30 DEG  C. when fermentation commences to form methane.  When fermentation is substantially complete the mass is removed from the silo and the greater part used as an agricultural compost whilst a smaller part is used to inoculate a fresh mass introduced into the silo.  The efficiency of the method may be increased by passing hydrogen gas and/or carbonic oxides (CO or CO2), e.g. coke-oven gas, through the fermenting mass.  The upper portion of the silo may be re-filled with a further mass of intensively comminuted and homogenized town garbage while partially emptying the lower portion thereof.ALSO:An organic fertiliser is formed during the production of methane by intensively comminuting and homogenising town garbage to form a mass having a moisture content lower than 60 per cent. and which is porous enough of having gases passed therethrough and heating the mass in a closed silo to a temperature at which methane fermentation commences, (see Group IV (b)).  The commination and homogenisation may be carried out by rotation in drums.  In an example intensively comminuted and homogenised town garbage is introduced into a closed silo which has a take off pipe for methane.  The silo is heated to about 30 DEG C. when fermentation commences to form methane.  When fermentation is substantially complete the mass is removed from the silo and the greater part used as an agricultural compost whilst a smaller part is used to inoculate a fresh mass introduced into the silo.  The efficiency of the method is increased by passing hydrogen gas and/or carbonic oxides (CO or CO2), e.g. coke-oven gas, through the fermenting mass.  The upper portion of the silo may be refilled with a further mass of intensively comminuted and homogenised town garbage while partially emptying the lower portion thereof.
