Title: Method of consolidating refractory materials
IPC: C04B35/20
Filed: 1947-06-02
Abstract: Granular refractory materials are consolidated at relatively low temperatures into masses of high refractoriness by selecting at least two refractory materials which will unite to form a highly-refractory compound which is capable of uniting with one but not the other material to produce as eutectic of relatively low melting point and reacting the eutectic in at least partly melted condition with the second of the two materials whereby a highly-refractory ceramically-bonded body is obtained through substantial elimination of the eutectic.  The eutectic may be a natural material or may be preformed from its constituents.  The eutectic may be formed from silica and lime, magnesia, alumina or zirconia.

Abstract: 1,149,671. Making metal strip, working at specified temperatures. ARMCO STEEL CORP. 31 March, 1967 [8 April, 1966], No. 14883/67. Headings B3A and B3V. A method of making coated ferrous strip includes heating the strip to 400-650‹ F., working the heated strip by flexing it sufficiently to strain its outer fibres, immediately quenching the strip and thereafter continuously levelling the strip to produce table-flat strip free from flutes and stretcher strain. The strip may be hot coated, e.g. galvanized, and in certain cases the temperature due to the residual heat from the coating operation will be sufficient for flexing, which is performed between rolls 12. Levelling of the strip is accomplished by passing it between tension bridles 16, 18, the precise elongation being determined by stretch rolls 20. When making galvanized strip, smooth ground temper rolls 26 may be used just ahead of the stretch rolls 20. The reduction effected by the temper rolls is 0À2 to 3% and preferably of the order of 2%. The strip is examined for flatness as it passes over an inspection table 22.

Title: Improved process for desulphurisation of gases and vapours
IPC: C10K1/20
Filed: 1932-05-30
Abstract: Sulphur is recovered from gases containing hydrogen sulphide or sulphur dioxide by passing the gases in contact with compounds of the alkali or alkaline earth metals in accordance with the following equations: CaSO3 + 3H2S = CaS + 3S + 3H2O 2CaS + 3SO2 = 2CaSO3 + 3S In carrying out the invention, a container is filled with one or other of the compounds and the corresponding gas passed over or through the mass which is regenerated by the passage of the other of the two gases, sulphur being removed by the use of water or steam. In a modification, the mixed gases may be employed, the thionic acids formed being removed by treatment with hydrogen sulphide.  In a second modification, ferrous sulphide and sulphite may be employed instead of the calcium compounds, hydrogen sulphide being first passed through a solution of ferrous sulphite.

Abstract: 529,207. Transformers. BRITISH THOMSONHOUSTON CO., Ltd. May 24, 1939, No. 15453. Convention date, May 24, 1938. [Class 38 (ii)] Taps 3 of an auto transformer 2 are brought out to con tacts 4 which are en gageable by a pair o clockwise - rotatable contacts 6, 7 to in crease the outpu voltage. In the posi tion shown, anc when the arm 7 is moving to the nex tap-contact, substan tially all the current flows through the arm 6, since the re sistor 10 is in serie: with arm 7, but when 7 reaches the nex tap-contact, circulating current flows through the resistor. If during this condition, or while the arm 6 is moving over to the next contact, so that arm 7 and resistor 10 are taking all the current, the switching movement is arrested for any reason and there is a danger of the resistor being burnt out, the fuse 9 blows and the switch arm 8 is moved by spring 12 over to contact 11 to insert reactor 13 into the circuit, so avoiding interruption of the supply until the fault is remedied. In Fig. 2, the upper supply lead 1 is connected to the centre tap of a reactor 14 which is normally short-circuited by the switch 8 at contact 15. In the conditions envisaged, however, the switch 8 changes to contact 11, so substituting the reactor 14 for the resistor 10. Since the load current normally divides equally between the two halves of the reactor, it has no injurious arcing effect on normal tap-changing operations. The Specification also shows how apparatus as in Fig. 2 can be added to existing circuits, using centretapped reactors, Fig. 3 (not shown).

Abstract: 827,242. Turbines. LEEDS & NORTHRUP CO. May 16, 1957, No. 15641/57. Class 110(3). [Also in Groups XXXV, XXXVIII and XL (a)] The speed of a turbine 12 driving an electric generator 11 is regulated in accordance with the output (actual or required) of the generator by arranging an electrical control system (see Group XXXVIII) to adjust the fuel, air and water supplies to the boiler 13 feeding the generator and the steam valve 67 in the pipe 58 feeding the turbine. The signals are obtained from the actual generator output, the required generator output, the temperature and pressure of the vapour entering the turbine and the oxygen content of the flue gases. These are combined in various ways to actuate a motor 77 which adjusts the setting of the speed governor 68 and the steam valve 67, as well as the air intake 57, the fuel input 85 and the water supply 37. The particular method of combining the electrical signals is stated to ensure efficient action of the turbine under changing lead conditions, e.g. by using the stored energy of the steam in the boiler to meet a sudden increase in load. The boiler described has little heat storage but the control system is equally applicable to those which possess such storage in the form of heat drums, and also to nuclear power plant. The system can be modified to deal with solid fuel, to maintain the transition from water to steam in a particular zone of the boiler, and to control such auxiliary equipment as flue-gas by-pass and recirculating dampers, tilting burners and desuperheating spray-water valves. Further refinements include electrical circuits for ensuring that when an increased output is called for when the steam pressure is already high the output is met mainly by opening valve 67 and to a lesser extent by increasing the fuel supply.
