Title: Improvements in gas turbine engines
Inventor: RODGERS HARRY FREDERICK
IPC: F01D17/16
Filed: 1959-05-20
Abstract: 875,411. Turbines. BRISTOL SIDDELEY ENGINES Ltd. May 20, 1960 [May 20, 1959], No. 17158/59. Class 110 (3). To vary the throat area of the turbine stator blading or one of the rows of stator blading to bring the engine within specified design limits, an opening extends through the turbine casing into which a plugging device to restrict the throat area of the working fluid passage between two stator blades may be inserted. The turbine stator assembly, Fig. 1, includes a casing 10 comprising an inner strength member 11 and an outer shell 12 of light construction. A flange 13 on the member 11 carries a ring 15 which supports a number of cast segments, each comprising an outer ring part 16 and an inner ring part 17 joined by a number of stator blades 18. In the example shown, there are eight segments completing the row of stator blades and each segment has an opening 22a extending through its surface 21 between two adjacent blades 18. The opening is continued through the member 11 at 22b and through the shell 12 at 22c. These openings constitute parts of a single opening referred to collectively by the reference 22. A sole plate 23 is welded to the shell 12 to provide a seating for a plugging device inserted into the opening 22. Two lengths of plugging devices are provided, both of which comprise identical outer members 29 having shanks 30 which project through the parts 22c, 22b of the opening 22. The two lengths of plugging device comprises inner members 32a, Fig. 5, and 32b, Fig. 1, which are similar in that each includes a shank portion 33, a plug part 34 which enters the opening 22a and a collar 35 with a lateral projection 36 which engages a slot at the outer end of the opening 22a. The two devices differ in that the shorter inner member 32a has a plug part 34, Fig. 5, of such a length that it extends substantially up to but not into the working fluid passage between a pair of stator blades, while the longer inner member includes an additional vane part 38 arranged to project into the working fluid passage. At its remote end, the vane 38 has a spigot 39 which engages a recess 40 in a boss 41 on the inner ring part 17 of the stator segment. The openings 22a are arranged between two stator blades 18 in the trailing edge region of these blades. The projection 36 locates the vane part 38 with its major chordal direction aligned with that of the blades 18. A spring 42 urges the collar part 35 inwards and allows for differential thermal expansion. The stator blading is designed so that with half of the openings 22 occupied by the longer plugging devices and the remainder by the shorter devices, the standard performance is obtained. A correction to the throat area of about 3% can be obtained by removing one or more plugging devices of one length and substituting others of other lengths.

Title: Improvements in or relating to organic oxidation reactions
IPC: C07B35/04
Filed: 1948-06-25
Abstract: Organic compounds are oxidized by reacting with an alkali metal hypochlorite and a minor proportion, e.g. up to 7 per cent, of an alkali metal permanganate or manganese dioxide in the presence of an alkaline medium such as caustic soda or caustic potash solution or lime.  Sodium hypochlorite is the preferred hypochlorite, particularly when used with potassium permanganate, the preferred permanganate.  When manganese dioxide is used it should preferably be freshly precipitated.  The oxidation effected may result in ring rupture, e.g. naphthalene to phthalic acid, oxidation of side chains, e.g. toluene to benzoic acid and p-toluic acid to terephthalic acid or non-cyclic compounds may be oxidized, e.g. 1,1,2-trichloro3,3,3-trifluoropropene-1 to trifluoroacetic acid. In examples: (1) 1,1,2-trichloro-3,3,3-trifluoropropene is slowly added to an aqueous solution of sodium hydroxide, sodium hypochlorite and potassium permanganate at 80 DEG  C. over 2 1/2 hours maintaining a reflux and then for 11 1/2 hours at 89 DEG  C., when unchanged trichloro-trifluoropropene is removed and the remainder made slightly acid with sulphuric acid, sulphur dioxide then being passed in until no colour is obtained with starch-iodide when the solution is neutralized with soda ash after filtration, evaporated to dryness and dried, the powdered residue being extracted with absolute alcohol and sodium trifluoroacetate obtained on removal of the alcohol; (2) toluene is added to a solution composed of the above oxidants maintained at 95 DEG  C. for 13 1/2 hours when benzoic acid is recovered in a conventional manner; and (3) naphthalene is added to an aqueous solution of caustic potash, sodium hypochlorite and potassium permanganate and refluxed for 29 hours when phthalic acid is isolated in a known manner.  Specification 577,481 is referred to.

Patent GB-499495-A (GB)
Title: The production of beryllium compounds from beryllium ores
IPC: C01F3/00
Filed: 1937-06-24
Abstract: Beryllium silicate ores, e.g. beryl, are roasted without fusion at for example 800-1200 DEG  C. with an anhydrous oxide, hydroxide, carbonate or bicarbonate of an alkali metal or a mixture thereof, and the mass comprising a neutral alkali silicate is decomposed by lixiviation in the hot, preferably at boiling, and at ordinary or elevated pressure with a solution or suspension of an oxide or hydroxide of an alkaline earth metal or of magnesium, or a hydrolysable salt thereof, e.g. a thiosulphate, sulphite, bisulphite or nitrite, which displaces the silica, and liberates the basic oxides, the beryllium being then extracted in soluble form by treatment with an alkali carbonate or bicarbonate produced in situ by the action of carbon dioxide, or by treatment with ammonium carbonate or bicarbonate.  When the roasted material is lixiviated by the above hydrolysable salts, sulphur dioxide or nitrogen oxides are evolved. In a modification, the ore is roasted without fusion at say 1100-1200 DEG  C. with an anhydrous alkaline earth oxide, hydroxide or carbonate or a mixture thereof, and the mass is decomposed at ordinary or elevated pressure, e.g. 5-6 ats., and in general at the boiling point by a dilute alkali hydroxide solution, whereupon the reaction mixture is treated by carbon dioxide, and the beryllium is separated in soluble form from the silica and alumina.  In both modifications, the beryllium is obtained as a solution of the carbonate in a carbonate or bicarbonate solution, and on boiling, basic beryllium carbonate is precipitated and is subsequently calcined to produce beryllium oxide.  The first modification of the invention is described with reference to a flow sheet.  Beryl and the alkali metal compound are calcined in a rotary furnace.  The carbon dioxide employed in the process is obtained by calcining calcium carbonate (marble), the calcium oxide produced being also used in the process as a solution of calcium hydroxide.  Alkali carbonate and bicarbonate separating during the process are re-employed for the calcination step.  Residues containing calcium carbonate and silica obtained may be used in the manufacture of cement.  The Specification as open to inspection under Sect. 91 comprises also the treatment of the reaction mixture produced by lixiviation of the roasted mass by dilute alkali hydroxide solution according to the modified process above with an agent such as calcium hydroxide at boiling before treatment by carbon dioxide.  In this case, the beryllium is separated in soluble form from insoluble silicate, aluminate or silico-aluminate.  This subject-matter does not appear in the Specification as accepted.ALSO:Relates to the extraction of beryllium silicate ores by roasting the ore with an oxide, hydroxide, carbonate or bicarbonate of an alkali metal, or with an oxide, hydroxide or carbonate of an alkaline earth metal, and treating the roasted mass by a series of operations.  Residues containing calcium carbonate and silica separated in the process may be used in the manufacture of cement.
