Abstract: A method for treating a combustion exhaust gas from an incinerator or from a metal smelting furnace, comprising the steps of: supplying powdered slaked lime to a combustion exhaust gas containing at least some of sulfur oxides, nitrogen oxides, hydrogen chloride, hydrogen fluoride and dust; subsequently introducing at least one material selected from ammonia, ammonia solution or urea solution into the combustion exhaust gas; causing the combustion exhaust gas aupplied with powdered slaked lime and combined with at least one of those materials to pass through a catalyst filter, wherein catalyst particles which are made of titanium oxide and vanadium oxide or of titanium oxide, vanadium oxide and tungsten oxide and which have diameters between 0..01 and 1 µm are carried by the filter, and wherein that filter is made by weaving monofilaments of a glass fiber with diameters between 3 and 15 µm so that the filter has a density of 400 to 1000 g/m2.      Preferably, the weight ratio of the catalyst components is TiO2 : V2Ox : WO x = 90-95 : 1-10 : 0-5, and the amount of the catalyst attached to the filter is 1 to 20 weight %.

Date Mar. 14, 1985.A gerotor pump is arranged for unidirectional flow irrespective of direction of rotation of the pump by arranging for displacement of the axis of eccentricity of the annulus and rotor upon drive reversal, the annulus being mounted in a carrier 14, FIG. 1, with freedom for movement in a first direction within the carrier, while the carrier itself is pivoted (24) in an outer housing 15, the carrier being free for movement in a second direction within the housing. The effect of normal drive of the rotor is to hold the parts in the FIG. 1 position while pumping continues, but in the event of drive reversal a pressure fluctuation causes the annulus to be displaced within the carrier and then the carrier to be displaced within the housing so as to bring the parts to substantially the mirror image of the FIG. 1 position allowing continued pumping in the same direction from inlet to outlet under reversed drive.

Abstract: A method of controlling a welding operation during arc welding between a fusible electrode and a workpiece, wherein the welding operation alternates between arc periods and short-circuiting periods, includes the steps of sensing a first parameter of the welding operation, for example the arc voltage between the electrode and the workpiece, generating a first signal representative of the first parameter, sensing a second parameter of the welding operation, generating a second signal representative of the second parameter, filtering the second signal to provide a filtered signal, generating a desired value signal based upon the filtered signal and controlling the welding operation based upon the difference between the desired value signal and the first signal. According to the method of the present invention, any changes in the second signal that occur at a frequency outside a predetermined frequency range, which includes a desired short-circuiting frequency of the welding operation, are attenuated such that the desired value signal is less affected by these changes than by changes occurring at a frequency within the predetermined frequency range. An apparatus for carrying out the method includes a band-pass filter having a pass band including the desired short-circuiting frequency.
