Abstract: A pipe curtain is formed by a plurality of pipes independently suspended at one end portion to an outwardly extending flange positioned around a pollution control hood positioned at the discharge of a metallurgical furnace. Molten metal is transferred from the furnace to a metal transporting vessel through a trough, spout or the like. The hood is positioned above the trough and fans for the hood draw emissions, such as gaseous and particulate pollutants emitted from the molten metal, into the hood. The vertically suspended pipes are positioned in close relation to each other and substantially enclose the space between the bottom edge of the hood and the upper edge of the trough. With this arrangement the pipes form a curtain that prevents the air entrained pollutants emitted from the molten metal from escaping out from beneath the hood to the surrounding atmosphere.

C. and lower than melting point of the reaction product and then subjected to drying, so as to improving the cation-selecting performance of the membrane and to increase its current efficiency.

Abstract: PCT No. PCT/SE78/00030 Sec. 371 Date Apr. 19, 1979 Sec. 102(e) Date Apr. 12, 1979, PCT Filed Aug. 11, 1978 PCT Pub. No. WO 79/00104 PCT Pub. Date Mar. 8, 1979.A method of producing blister copper from raw material containing antimony. The invention is characterized in that a slag is separated from copper matte formed by smelting the raw material. Thereafter the matte is brought into contact, under violent agitation preferably in a rotary converter of the Kaldo type, with a substantially inert gas in a quantity sufficient to reduce by volatilization the antimony content of the copper matte and, possibly, also the content of other impurities such as bismuth, arsenic and zinc to a level acceptable when performing the subsequent converting process, so as to obtain the desired blister copper product, preferably a maximum content of antimony, 0.04 percent by weight and of bismuth 0.03 percent by weight. The rotary converter is suitably operated with a rotation corresponding to a peripheral speed of approximately 0.

Abstract: Combination of a nonionic oxyalkylated alcohol surfactant and an engine fuel, e.g. a 50--50 mixture, by volume, of such surfactant and an aircraft engine fuel such as JP-4 jet fuel, consisting essentially of a mixture of gasoline and kerosene, which is miscible both with water-based and oil-based liquids, for removing water or water-based leak tracer solution entrapped in a fuel tank system, e.g. of an aircraft. When employing, for example, an aqueous leak tracer solution introduced into a fuel tank, e.g. of an aircraft, for locating any leaks therein, after inspection and removal of the main body of leak tracer solution from the tank, in order to remove any residual leak tracer solution which remains entrapped in the tank, the invention composition, hereinafter termed a "depuddling agent", is introduced and blends with the residual leak tracer solution, and the resulting miscible mixture is drained from the system.

Abstract: In a plasma chemical reaction carried out with at least one gas, the plasma constants in the progress of reaction such as electron temperature, electron density and electron energy distribution function can be measured by use of a probe heated to a high temperature which is made of a metal having a small thermionic electron emission at a high temperature. The plasma chemical reaction can be performed in the steady state with satisfactory reproduction of composition, structure, yield and performance of the product by controlling the pressure, input power and gas flow rate in the plasma reactor so that the measured plasma constants always coincide with the predetermined plasma constants necessary for effecting the intended chemical reaction which have been obtained through a preliminary experiment.
