Abstract: 593,893. Gas turbines. BRITISH THOMSON-HOUSTON CO., Ltd. June 19, 1945, No. 15651. Convention date, June 20, 1944. [Class 110 (iii)] A gas turbine has an annular sealing plate 18 extending between the bearing 4 and the inner cylindrical wall of the nozzle box 6, the plate being loosely sealed at its inner and outer edges to the bearing and nozzle box respectively. The turbine and a centrifugal compressor 5 driven thereby comprise an exhaust-driven turbo-supercharger for an aircraft engine. The inner sealing means comprises a sealing ring 34 which has a snug but floating fit on a cylindrical portion of the bearing cap 15 and has a light frictional engagement in a sealing groove 30. The latter is formed by means of a ring 31 and a spacer 32 secured to the sealing plate 18 by rivets 33 or by welding. An outer offset portion 25 projects loosely into a sealing groove 26 which is formed between a flange 27 on the nozzle diaphragm and a ring 28 secured thereto by welding 29. The intermediate conical portion 21 of the sealing plate 18 is braced against lateral deflection by brackets 22 attached thereto and to a baffle 10 by welding. The baffle 10 divides the space between the bearing and the nozzle box into annular passages 13 and 14 for the flow of cooling air for the bearing. The cooling air may be derived from a ram air intake, not shown, facing the aircraft slip-stream. Leakage of gases through the clearance space between the nozzles 7 and buckets 2 is reduced by an annular channel member 35 which is welded to the sealing plate 18 and forms a close clearance with the bucket wheel 1.

Title: Improvements in or relating to the removal of hydrogen sulphide from gases or liquids
IPC: C10K1/12
Filed: 1933-06-01
Abstract: Alkaline liquors, e.g. aqueous sodium or potassium carbonate, which have been used for scrubbing gases or vapours containing hydrogen sulphide are freed from hydrogen sulphide in a three stage process which comprises treating the fouled liquor with carbon dioxide, boiling the so treated liquor, and finally treating the thus regenerated liquor to remove the hydrogen sulphide still contained therein.  The liquors may be thereafter returned to the scrubbing step.  The regenerated liquors may be treated in the third stage with an oxidising agent such as a peroxide or by aeration with air or oxygen in the presence of a catalyst.  The peroxide may be hydrogen peroxide or a peroxide of an alkali or alkaline earth metal, e.g. barium or sodium peroxide. These peroxides may be added to the liquors in the form of a solution or fine suspension in successive small quantities with agitation.  Alternatively, the liquor may be passed through a bed of catalyst with simultaneous aeration in the third stage.  The catalyst may consist of a mixture of the hydroxides of iron and chromium precipitated together on a support such as coke. The examples relate to the regeneration of aqueous potassium carbonate solutions used in scrubbing coal gas.  The first Provisional Specification describes also the general application of peroxides for the removal of small quantities of hydrogen sulphide from liquids such as regenerated scrubbing liquors or gas holder water.ALSO:The first Provisional Specification describes the use of peroxides, e.g. hydrogen, sodium or barium peroxide, for the removal of small quantities of hydrogen sulphide from liquids, e.g. gas holder water.
