    摘要: A method of and apparatus for the mixing of a slurry in a tank having a conical bottom along the axis of the tank, and air-lift pipe is provided which is supplied at its lower end with compressed air to induce an upward flow of the slurry and air mixture through the pipe during start up of a mixing operation. Thus an injection is cut off when steady state is reached and air is injected at an upper level in the pipe located in the upper third of the length thereof but below the upper eighth for continuing mixing operation.

    摘要: The invention relates to an emulsifiable microemulsion concentrate containing a phophoric acid ester and/or thiophosphoric acid ester as active ingredient. In addition to 20 to 80% by weight of active ingredient, the composition comprises: 7 to 70% by weight of a nonionic surface active agent, preferably a block copolymer with a molecular weight of 1000 to 10000 formed from polyethylene oxide and polypropylene oxide, an alkylphenol polyglycol ether, ethoxylated fatty alcohol or a mixture of nonionic surface active agents; 2 to 50% by weight of water; if desired, 1 to 50% by weight of a co-surfactant, preferably C.sub.1-8 straight or branched chain and/or cyclic alcohol, C.sub.3-8 straight or branched chain and/or cyclic ketone, esters of C.sub.1-6 fatty acids with C.sub.1-6 alcohols or the mixture thereof; and if desired, 15 to 30% by weight of a water-immiscible organic solvent.
