Abstract: Abstract A method of at least partially burning a hydrocarbon and/or carbonaceous fuel in order to yield hot gaseous products of relatively low pollutant content, in which the fuel is partially burned in a first stage flame under such conditions that the partially combusted fuel has a tempe-rature in the range 800 to 1600°C (e.g., about 1150°C) and is sub-stantially free of smoke and/or carbon, bringing the partially combusted fuel at 800 to 1600 C into contact with a substantially non-volatile catalyst (19) which is active for reducing the amount of NOx in the partially combusted fuel, and then at least partially burning the partially combusted fuel, after contact with the catalyst (19) in a second stage flame to yield the desired low pollutant hot gaseous products.  Preferably one or both of the said flames burns in contact with a substantially non-volatile catalyst (25, 23) to reduce still further the NOt  content of the final gaseous products.  The preferred non-volatile catalysts (19, 25, 23) comprise either a mixture of iron and chromium oxides or cobalt oxide.

Abstract: ABSTRACT            In a method of manufacturing for a railway switch-point concrete sleeper blocks (15?) of varying lengths and having different number of attachment means (15?b) located in mutually different positions for the attachment of rails to said blocks there is used a plurality of steel matrices (2) whose respective lengths correspond to the desired lengths of the various sleeper blocks and which exhibit detachably mounted dowels (3). The matrices are placed end to end in an elongate mould bed with the dowels facing upwardly, whereafter reinforcing lines (5) are tensioned and concrete is east into the mould bed and permitted to harden. The thus formed coherent concrete body (15), whose length may exceed 30 meters  is then removed from the mould and the matrices (2) removed and the dowels (3) remaining east in the concrete block. The concrete body (15) is then cut into sleeper blocks (15?) of desired length. The same matrices (2) can be used for the manufacture of sleeper blocks for both left-hand and right-hand switch-points, said matrices being turned and the dowels (3) being mounted on different sides of the matrices in the two cases.       The invention also relates to a matrix array for use in the described method. Each matrix is provided on both sides thereof with mirror-image markings which provide a clear print in the finished sleeper block, said imprint indicating the type of switch-point intended and the sequence number of a respective block among the sleeper blocks associated with said switch-point.            The sleeper blocks and rails associated with a particular railway switch-point can be assembled together, transported to and placed on the site in question along a railway track while using conventional track-laying machines.

Abstract: ABSTRACT OF THE DISCLOSURE:         The invention is concerned with a process for the pro-duction of reducing gas from solid fuels, in which a reducing gas which consists in at least 80% by volume of the components hydrogen and carbon monoxide and is intended for use in the reduction of ores is produced by the gasification of solid granular fuels in a fixed bed by a treatment with oxygen and steam under a pressure in the range of 5 to 50 bars.  The process of the invention is characterized in that the gas produced by the gasification is subjected to shift conversion in order to reduce its residual car-bon monoxide content to about 1 to 10 by volume of dry gas, the shift-converted gas is scrubbed to remove the sulfur compounds and to reduce its CO2 content to 3% by volume, at most, and to provide a scrubbed gas which consists in more than 70% by volume of hydro-gen and carbon monoxide and contains more than 10% by volume of methane, the scrubbed gas is mixed with a reduction process exhaust gas formed by the reduction of ores, the mixed gases are reformed under a pressure of 1.5 to 10 bars and at temperatures of 800 to 1500 °C, and at least partly reformed gas, which contains up to 3% by volume of CO2 and up to 5% by volume of methane and is at temperatures of about 700 to 1000 °C, is fed to an ore-reducing plant as reducing gas.  In the process of the invention, the CO2 of the gas produced by the gasification of fuel is shift-converted to such a degree that it is not necessary to remove CO2 from the reduction process exhaust gas formed by the reduction of ores.
