Abstract: In a process for preparing a molding from fibers and/or flakes and thermoplastic binder, the material is introduced into a mold, compacted, and bonded by thermal effect. To make it possible to introduce the material rapidly and such that a consistently equal density or a density changing in a defined pattern will be obtained, a filling contour calculated for the given molding is formed by a first mold disk set. After filling the filling contour, a first finished contour mold is positioned against it. A second mold disk set, whose disks are displaceable between the disks of the first mold disk set and form the second finished contour of the molding, is subsequently displaced in the first mold disk set against the first finished contour mold, while the material present in the filling contour is compacted. The material is subsequently fixed by thermal effect.

Abstract: A process for the agglomeration of coal fines comprises the steps of mixing the coal fines with an agglomerating liquid which is further comprised of a reagent and a solvent portion. The coal fines are thereafter separated from the agglomerating liquid, dried, and preferentially compressed into pellet form. The process also entails the recovery and return of the agglomerating liquid. The agglomerating liquid of the present invention includes the reagent portion which is a member or a combination of the group consisting of aromatic tertiary amines, nonaromatic cyclic amines or primary organic amines. The solvent is an organic solvent, desirably a member or a combination of the group consisting of toulene, chloroform, carbon disulfide or dimethylacetamide. The pellet formed from the process of the present invention is uniquely water resistant and of controllable hardness.

Abstract: A dehydrator for use in washing clothes or the like includes a dehydration tub mounted in an outer cabinet, a brushless motor for rotating the dehydration tub for a dehydrating operation, and a microcomputer-based controller for controlling the rotational speed of the motor so that the motor is rotated at a plurality of different rotational speeds sequentially during the dehydrating operation. The different rotational speeds include a maximum rotational speed ranging between a rated rotational speed or above and a rotational speed corresponding to a resonant point of the outer cabinet.

Abstract: The invention concerns a method for controlling a press filter, said press filter having electric motors for operating said press filter. At least one of said electric motors of said press filter is driven by a frequency filter. A logic control unit is used for sending a program-controlled analog signal to said frequency converter. The output current from said frequency converter having a frequency proportional to the magnitude of said analog signal received from said logic control unit is used for driving the press filter's electric motors, whose rotational speeds thereby become proportional to the drive current frequency. A desired electric motor is individually started by way of applying power to the motor via a switch element which is activated by a signal from the logic control unit.

Abstract: This invention relates to a process for treatment of pigments and the compositions of treated pigments using the disclosed process. Particularly, this invention describes a process for producing non-dusty, free flowing, granular pigment materials in which the pigment is treated by a water-dissipatable polyester. The treated pigment materials generally exhibit high dispersibility in water and polar solvent systems. Dispersions of such materials provide film-forming characteristics, water-resistivity and excellent adhesion when applied to the skin. The pigment materials prepared by the disclosed process are suitable for incorporation in paints, inks, cosmetic bases, liquid make-ups or other cosmetic preparations such as mascara.

Abstract: Uniform spherical granules are produced from powder raw material without utilizing an agglomerating liquid by repeatedly and alternately compacting a dry powder raw material within a granulating vessel to cohesively form agglomerates of the material and fluidizing the powder material within the vessel to break up and form the agglomerates gradually into a uniform spherical shape.

Abstract: Shaped articles of agglomerated particulate material are prepared by conveying plates having apertures therethrough on a surface for forming, by reason of the plate apertures and the forming surface, article shaping cells. Particulate material to be formed into the shaped articles is fed into the cells, and then while the plates remain on the forming surface, the particulate material in the cells first is tamped, and then while the plates ascend from the forming surface, the tamped material is ejected from the cells onto the forming surface in a form of shaped articles.
