Abstract: 857,811. Heating steam boilers by waste gases; controlling steam temperature. COMBUSTION ENGINEERING Inc. April 10, 1959 [April 28, 1958], No. 12171/59. Classes 123(2) and 123(3) [Also in Group XXVI] A power plant installation comprises a steam boiler and a gas turbine, means being provided for passing a portion of the turbine exhaust gases into the furnace of the boiler to support combustion of fuel therein, the remaining portion of the turbine exhaust gases being arranged to by-pass the boiler furnace. The boiler feed water is pre-heated in an economizer disposed in the exhaust gas by-pass, and the steam generated in the boiler is superheated in two stages-a low temperature stage disposed in the exhaust gas by-pass and a high temperature stage disposed in the boiler furnace. The plant shown comprises a gas turbine 10 driving a generator 54 and a steam turbine 52 driving a generator 56, steam being supplied to the turbine 52 from a steam boiler 20. Exhaust gases from the gas turbine 10 pass through duct 14 and then divide into two streams, one passing through duct 18 to enter the boiler furnace and the other passing through by-pass duct 22 to the exhaust stack 24. Boiler feed water is pre-heated in the economizers 38, 42, the economizers 38 'being heated by combustion gases from the boiler furnace and the economizer 42 being heated by the portion of turbine exhaust gases passing through duct 22. Steam generated in the boiler passes from the steam drum 28 to the low temperature superheater 44 where it is heated by the portion of the turbine exhaust gases flowing through duct 22. The super-heated steam is then further superheated by combustion gases in the superheater 32 and finally passes to the turbine 52. The flow of turbine exhaust gases to the ducts 18 and 22 is controlled by means of dampers 60, 62. The boiler is so designed that it will develop the design pressure and temperature at maximum load when the gas turbine is shut down and the boiler is supplied with atmospheric air. Variations in total load may be met by varying simultaneously the output of both the gas turbine and the boiler, by varying the output of the gas turbine while maintaining the output of the boiler constant, or by varying the output of the boiler while maintaining the output of the gas turbine constant.

Title: Improvements in or relating to the production of vitamin
IPC: A61K31/00
Filed: 1956-04-20
Abstract: Substantially pure Vitamin B12 is separated from impure aqueous concentrates containing it together with undesired accompanying factors predominantly of an electroneutral character, by extraction from the concentrate with a mixture of a non-polar solvent and a solvent containing a phenolic hydroxyl group, adsorption from the solvent phase on to a microporous inorganic adsorbent and elution from the adsorbent with a polar solvent from which the Vitamin B12 is crystallized.  When using a mixture of phenol and chloroform in the initial extraction, the ratio of these components is preferably 1:6. Alternatively as phenolic solvent there may be used cresol or chlorophenol and as the non-polar solvent there may be used carbon tetrachloride, ethylene chloride and benzene.  As adsorbent, aluminium oxide, fuller's earth, diatomaceous earth and silica gel may be employed.  The aqueous polar solvent employed in the final elution may be acetone, ethanol or propanol.  Adsorption may be effected by adding the adsorbent directly to the solvent phase. The adsorbent is separated therefrom, e.g. by filtration.  An example describes the process in detail.  Specifications 675,247 and 677,487 are referred to.
