Abstract: The invention relates to a method in the gasification of sulphur-containing carbonaceous material using metal smelts. When gasifying such carbonaceous material in a metal smelt, the material is introduced to a gasifying reactor containing an iron and/or manganese smelt having a temperature of between 1100 DEG  and 1600 DEG  C., suitably 1150 DEG -1250 DEG  C., the smelt being substantially saturated with respect to sulphur and carbon. The carbonaceous material is oxidized to carbon monoxide and the sulphur content forms a matte phase containing a high percentage of sulphur, which phase is tapped off. Residual non-combustible material is collected as a slag on the surface and is removed together therewith. If so desired, the matte can be granulated and roasted to recover the sulphur and metal contents. Carbonaceous material incorporating pyrolysible constituents is suitably pyrolysed in a pyrolysis medium at a temperature of between 450 DEG -800 DEG  C. prior to the gasification reaction, the temperature during the pyrolysis process being maintained, by circulating the pyrolysis medium between pyrolysis and gasification and optional combustion of carbon monoxide gas formed.

Abstract: The invention provides a novel magnetically traceable or detectable explosive blended with a magnetic ferrite powder which facilitates the detection of the misfired explosive, e.g. dynamite, remaining in the field after blasting by a magnetic means but not to adversely affect the stability of the explosive. The ferrite powder is freed of any free alkalinity on the surface before blending with the explosive either by washing with water, neutralization with a dilute acid, reaction with an acid followed by washing with water or neutralization with an alkali and/or by coating with a polymeric material on the particles. The most efficient method for the coating of the ferrite powder with a polymeric material is the in situ polymerization of a radical-polymerizable monomer in contact with the ferrite particles in the presence of hydrogensulfite ions and the explosives blended with such a polymer-coated ferrite powder retain their stability even after a prolonged storage.

Abstract: A method for controlling the air- to-fuel ratio of the mixture fed to an engine or other combustion device has the air-to-fuel ratio periodically altered towards stoichiometric into the response range of a conventional exhaust gas sensor. The output of the sensor at stoichiometric establishes a reference point setting of the air-to- fuel ratio proportioning device (e.g., carburetor) whose adjusting element is then moved a selected distance away from its setting point to provide a selected value of air fuel ratio which may be outside the normal response range of the sensor, either rich or lean of stoichiometric. The apparatus described includes a sensor 181 which generates an output signal which is compared against a reference signal by a comparator 28. When the output signal exceeds (or falls below) the reference signal, a timer B allows the proportioning device 42 adjusting element to be moved in the desired direction for a stated interval of time. A separate timer A operates the adjusting element towards stoichiometric at selected intervals to periodically establish the reference point setting. <IMAGE>

Abstract: Ventilation strip for ventilation of exterior sidings in building constructions. The strip has horizontal apertures which provide possibility for ventilation and for leaking out of penetrating water and condense. The apertures of the trip have an airflow that is more than 50% of the ventilated cross-sectional area (4). Combined with support surfaces (14), the longitudinal ribs (9) create chambers (13), that via the vertical holes (12) are ventilated to the horizontal apertures (10). The vertical holes provide an easy way of setting up the strip, because they are used for nails whereby the strip is kept in position until the siding is mounted. Furthermore, the longitudinal ribs (9) make a funnel for the condense-and-penetrating water that accumulate in the ventilated space (4). The water is conducted into the ventilation strip (8) and passes out without damaging the construction and the siding (7). In the channel (15) in the strip a diagonal net (10) is placed preventing entry of animals and insects, which could cause problems in the construction. The diagonal net (11) makes it possible for water to leak out and for air to pass by in an amount which is more than 50% of the ventilated cross-sectional area. The ventilation strip (8) presses tight to the supporting sides (14) and keeps the weather protection felt (3) tight, and thereby avoids leaks in the construction.

Abstract: Method in the manufacture of sulphuric acid from substantially dry gas containing sulphur dioxide and generated when treating mercury-containing raw materials and intermediate products, for obtaining pure sulphuric acid and a high-grade mercury product. The gas is cleansed of accompanying gaseous mercury, by bringing the gas into contact with sulphuric acid in one or more stages (1, 2) so that the major part of the mercury is absorbed in and dissolved in concentrated sulphuric acid having a concentration of at least about 90%, whereafter the purified gas is supplied to a contact plant (4) for the production of pure sulphuric acid. The invention is characterised by circulating the concentrated sulphuric acid in a circuit which comprises at least one drying tower (2), for the sulphur-dioxide-containing gas, a sludge separator (19) and an oxidation reactor (3). Gaseous elementary mercury accompanying the gas in the drying tower (2) is oxidized and absorbed in the acid, and isolated mercury compounds are separated from the acid and removed from the circuit. The thus purified acid is then brought into contact with an oxidant in the oxidation reactor (3), so that dissolved mercury present in the acid is oxidized to mercury (11) ions, which are then used in the drying tower (2) for promoting oxidation of elementary mercury.

Abstract: In a method for facilitating the striking of a pilot arc and main arc in plasma arc cutting torches in plasma gases that are difficult to ionise, when cutting workpieces covered with an electrically insulating surface layer, without establishing electrical contact between nozzle and workpiece, a direct current voltage source is connected on the one hand to the electrode E of the plasma arc cutting torch, and on the other in series with a resistance R to the cutter nozzle D, and an ignition element, which by way of a transformer T generates an ignition pulse between electrode and nozzle. Plasma gas is fed to the gas duct between electrode and nozzle. The ignition pulse energy necessary for ionisation of the plasma gas is kept constant.  The ignition pulse is given a duration and polarity in relation to the direct current voltage source such that the pilot arc is established without the involvement of an auxiliary starter circuit. An ignition pulse is produced at a point in time essentially equal to 0.3T, where T is the time constant of the gas system. The time constant T is selected having regard to the area in the inlet and the nozzle duct and the gas flow volume between valve device and nozzle, so that the gas flow at the point 0.3T is essentially equal to 0.3φ max, where φ max is the maximum plasma gas flow, at which the pilot arc is struck by the ignition pulse at the point 0.3T and at the gas flow 0.3φ max. The current-voltage characteristic of the direct current voltage source and the series resistance R in relation to the maximum gas flow φ max are selected in such a way that the pilot arc goes out at point T, and the pilot arc during its burning time T-0.3T melts the surface layer on the workpiece, so that a main arc is established. <IMAGE>
