    摘要: An improved dry process for the finishing of organic material, particularly textile material made from natural or synthetic organic fibres ist described, which comprises applying to an inert carrier preparations containing at least one textile finishing agent transferring at atmospheric pressure above 80.degree.C to the organic material, optionally a bonding agent stable below 250.degree.C, water and/or an organic solvent; drying of the said preparation; bringing into contact then of the treated side of the inert carrier with the surface of the organic material to be finished; subjecting thereupon of carrier and the material to be finished, optionally under mechanical pressure, to a heat treatment at a temperature of at least 80.degree.C until the said textile finishing agent has transferred to the material to be finished, and separating of the finished material from the carrier.The advantage of the new process is that, since there is no effluent produced, it is possible to use also textile finishing agents which are not biologically decomposable and it offers the possibility of obtaining finishing effects on the inside which differ from those on the outside surface of a fabric, such as is desired in the practice.

    摘要: Aluminous ore such as bauxite containing alumina is blended with coke or other suitable form of carbon and reacted with sulfur gas at an elevated temperature. For handling, the ore and coke can be extruded into conveniently sized pellets. The reaction with sulfur gas produces molten aluminum sulfide which is separated from residual solid reactants and impurities. The aluminum sulfide is further increased in temperature to cause its decomposition or sublimation, yielding aluminum subsulfide liquid (AlS) and sulfur gas that is recycled. The aluminum monosulfide is then cooled to below its disproportionation temperature to again form molten aluminum sulfide and aluminum metal. A liquid-liquid or liquid-solid separation, depending on the separation temperature, provides product aluminum and aluminum sulfide for recycle to the disproportionation step.

    摘要: A method of preparing carbonaceous blocks or bodies for use in a cathode in an electrolytic cell for producing aluminum wherein the cell contains an electrolyte and has molten aluminum contacting the cathode, the cathode having improved wettability with molten aluminum. The method comprises the steps of providing a carbonaceous block and a boron oxide containing melt. The carbonaceous block is immersed in the melt and pressure is applied to the melt to impregnate the melt into pores in the block. Thereafter, the carbonaceous block is withdrawn from the melt, the block having boron oxide containing melt intruded into pores therein, the boron oxide capable of reacting with a source of titanium or zirconium or like metal to form titanium or zirconium diboride during heatup or operation of said cell.
