Abstract: Aqueous solutions of amide polymers, such as poiyacry- lamide when treated with small amounts of a water-soluble polyaldehyde and a hypohalite salt at an alkaline pH, react to form firm gels within a short time at ambient temperature. Such gels, which are stable under alkaline as well as acidic conditions, are usefully employed to plug porous subterranean formations, for grouting of leaking soil pipes or wells, and to otherwise render porous structures impermeable to the passage of liquids such as water.

Abstract: In order to avoid damage during processing and/or to improve the processing and service properties of polyolefin powders, these powders are homogeneously mixed with additives. This homogeneous mixing is achieved by mixing the polyolefin powders and the additives using rotating blades with a blade frequency of from 100 to 300 per second at a power of from 370 to 1280 Wh/m<3> of powder. During this operation, the powder is passed through a zone having an energy dissipation density of from 200 to 350 W/l of mixer volume.

Abstract: The invention relates to apparatus for spreading fibres uniformly over a forming surface, wherein a fibre distributor chamber (10) is furnished with an impeller (14 etc.) to eject fibres onto the forming surface which comprises a foraminous conveyor (28) to create a fibrous, felted mat on the conveyor. The distributor has a fibre discharge opening provided with a foraminous screen through which the fibres are ejected. …<??>To prevent anisotropy in the mat arising from the fibres tending to align themselves with the direction of travel of the conveyor (28), the discharge opening screen (12) is continuously movable across the said opening in the same direction as the conveyor (28) and at substantially the same speed. The fibres come to rest on the conveyor (28) randomly oriented and the resulting mat has substantially isotropic properties.

Abstract: The present invention relates to a fly ash utilization process or system for the removal of sulfur dioxide from the flue gas of coal fired boilers. 
<??>In one embodiment, a high ionic concentration is maintained in a closed loop, water balanced system which is operated at a low pH, i.e. less than 4 and preferably less than 3. The ionic concentration of the scrubber slurry is maintained at at least 5,000 parts per million of alkali metal cations, preferably over 10,000 parts per million, at least a substantial portion of which has been leached from fly ash. 
<??>The ionic concentration of the scrubber slurry is maintained at a high level by providing small diked areas (38, 42) in a waste pond (34) for settling of undissolved solids wherein the returned supernatant has a high ionic concentration. 
<??>A principal advantage of the system is that there is a substantially reduced liquid-to-gas ratio required for scrubbing SO2, with substantial savings in pumping and power requirements for the system.

Abstract: A metallic sintered body having fine pores of uniform size, e.g. pore size of 10 µm. or less and moreover having a high porosity, e.g. 50 % or more. The sintered body is useful as a filter for precisely filtering off fine contaminants, and the filter has a high filtration capacity and a long filtration life. The sintered body is prepared by compacting fine metallic particles surface-treated or admixed with a thermosetting resin by means of hot pressing and sintering the resulting compact. Since the thermosetting resin hardens upon hot pressing to give a compact having a good strength, the workability is good and a multiplicity of the compacts can be sintered at one time.
