Title: Gas-steam turbine plant
IPC: F01K21/04
Filed: 1966-06-15
Abstract: 1,088,784. Gas turbine plant; gas turbine combustion chambers. SULZER BROTHERS Ltd. June 15, 1966 [May 6, 1966], No.26634/66. Headings F1G and F1L, A turbine plant has a combustion chamber 4 with means for maintaining a water film on the internal wall surface 6 so that steam is produced by the heat of combustion, the steam mixing with the combustion gases within the combustion chamber and flowing through a pipe 8 to drive the plant turbines 46, 47. Turbine 47 drives a generator 15. Combustion air is supplied to the burner 5 of the combustion chamber by turbine driven compressors 1, 3 having an intercooler 2 which pre-heats the water being pumped to the combustion chamber and to an additional water injection point 7 downstream of the combustion chamber. The amount of water injected at 7 is controlled by a temperature sensing unit 9. The exhaust from turbine 47 passes through a heat exchanger 48 to effect further pre-heating of the water. Demineralizers 12, 14 are provided in the water line. The combustion chamber may comprise, Fig. 2 (not shown), an outer casing (16) with insulation (30) surrounding an inner double walled cylindrical or frusto-conical liner (17). The water is fed through pipes (18) to a distribution trough (19) at the top of the liner and thence over the edge of the trough or through drillings to cover the entire internal surface of the liner with a film of water. Any water not evaporated to steam collects in a sump (20) at the bottom of the combustion chamber from which it flows to a balance tank (21). The water level in the tank and in the combustion chamber is maintained constant by a level controller (26, 27). Water is pumped back from the balance tank to the distribution trough (19). The liner (17) is cooled by water in a space (32) between its walls. Additional water is sprayed into the combustion chamber by a nozzle (7). In a modified combustion chamber, Fig.3 (not shown), there are three adjacent liner sections (33, 34, 35) and water is sprayed by nozzles (36) to form a film on the upper liner (33) which runs down to collect in distribution troughs (37, 38) in the intermediate and lower liner sections (34, 35), respectively. In this modification, the internal walls of the liners have indentations of projections or are formed from perforated plate to reduce the velocity of the water film. In a further modification, Fig.4 (not shown), the combustion chamber has several burners 5 and associated liners.

Abstract: 1,176,541. Cathode-ray tube displays. INTERNATIONAL BUSINESS MACHINES CORP. 9 June, 1967 [13 June, 1966], No. 26660/67. Heading H4T. In a data display system the display is controlled by a circulating series of control word signals utilized successively, each control word defining the location on the display device at which the data is to be displayed and when required, including signal elements controlling the display of a marker symbol at a location at which the data may be selectively changed, the system including means for detecting a control word including such signal elements, means for deleting the latter from such word and means for inserting such signal elements in another control word, the data appertaining to which may be changed, in the series. The invention is described in connection with a system in which Alpha-Numeric and graphic data derived, together with the control words, from a central, programmed processor controlled by a remote operator and displayed on a cathode-ray tube may with certain exceptions be modified by a local operator via a keyboard. The exceptions are character data (Alpha-Numeric) termed " protected " comprising format or other data which the operator requires, e.g. in a rail or airline reservation system. The received data are stored in a buffer in separate fields each appertaining to a different type of data identified by unique codes (commands) such data being fed to the display cathode-ray tube to produce the display by controlling the beam deflection and being fed-back to the buffer for recirculation so that a continuous display is produced. The control words each comprise nine bits of which bits 0-7 are utilized to define information relating to the character and the graphic data and two bits are utilized to control, when required, the production of the marker symbol which comprises a cursor line. The system operates in a question and answer mode in which the local operator, by using his keyboard, can insert data, in a display produced under control of the processor, at a position indicated by the marker symbol and at will can vary the position of the latter and change or alter data, unless protected, all keyboard operations being sent back to the central processor.

Title: Improvements in the production of nitrocyclooctane
Filed: 1952-10-24
Abstract: A process for the production of nitrocyclo-octane consists in treating cyclo-octane in a closed vessel at temperatures between about 100 DEG  C. and 150 DEG  C. with an aqueous solution of nitric acid containing from about 20 to about 55 per cent of NO3 ions or with a solid metal nitrate hydrate with about the same content of from 20 to 55 per cent by weight of NO3 ions.  Suitable salts are nitrate hydrates of aluminium (Al(NO3)3.9H2O), zinc (Zn(NO3)2.6H2O), copper (Cu(NO3)2.6H2O) or iron (Fe(NO3)3.9H2O).  The reaction may be effected in an autoclave or continuously in a high-pressure tube.  In examples (1) cyclo-octane is heated at 110 DEG  to 120 DEG  C. in a pressure vessel with nitric acid of 32 per cent. strength, the pressure rising to 30 atmospheres.  Nitrocyclo-octane is obtained together with small amounts of polynitro compounds, suberic acid, and lower molecular dicarboxylic acids such as succinic acid. The product is soluble in alkalies; from a solution in 40 per cent caustic soda solution the sodium salt precipitates.  From a solution of the product in caustic potash solution the aci form is precipitated on acidification.  (2) Nitrocyclo-octane is obtained by heating cyclo-octane at 110 DEG  C. with aluminium nitrate (Al(NO3)3.9H2O) in an autoclave.

Abstract: 1,149,541. Measuring extension electrically. BRITISH AIRCRAFT CORP. (OPERATING) Ltd. Sept.26, 1966 [June 25, 1965], No.27086/65. Heading G1N. The extension of a specimen of elastic material, e.g. rubber or plastics, under load is measured by fixing two clamps 32, 33, Fig.2, on the specimen 11 a predetermined distance apart. Relative movement of these clamps, as the part 10 of the specimen between the clamps extends under load, is detected by mechanically connecting the clamps to a circuit, including a potentiometer, whose output gives an indication of the extension. In the embodiment, the specimen is held between two eccentric roller grips 13, 14, Fig. 1, on sliders 13a, 14a, which are free to move along parallel bars 15. The sliders are gradually drawn apart by a cable 16 forming part of a variable speed winch system 17, 18, 19. A beam dynamometer 20 is used to measure the load on the specimen and its output signal is fed, via lead 21, to the 'Y' axis of an autographic plotting table (not shown). Movement of the clamps is transmitted to two rotary potentiometers 30, 31 via wire cords 40, 49, 40a, 49a and a system of pulleys 45, 46, 48, 50, 51, 55, 56 and 45a, 46a, 48a, 50a, 51a, 55a, 56a, the cords 49, 49a being wound round pulleys 53, 53a fixed to the shafts 54, 54a of potentiometers 30, 31. The differential output signal from the two potentiometers is fed to the 'X' axis of the plotting table, whereby a graph of load v. extension is obtained. Alternatively a single rotary potentiometer may be used, the cords 49, 49a being connected to rotate the shaft and body of the potentiometer respectively. To arrest sudden motion of the slider 14a, e.g. when the specimen breaks, it may be provided with a brake comprising a pair of shoes (64), Fig. 3 (not shown) which may be swung down to grip the bars 15. The shoes are connected through arms 65, 67 to a weight 68, so that sudden movement of the slider to the left will cause the shoes to be swung down as a result of the inertia of the weight 68. For hot-testing, the apparatus may be enclosed in a three zone furnace 70 movable on tracks 71. Similarly, for cold testing, the apparatus may be enclosed in a liquid air cooled unit.
