Abstract: The invention discloses a dispersion of deagglomerated barium sulphate having an average primary particle size of <0.5 ?m and coated with a dispersant in defined organic solvents, especially halogenated solvents such as dichloromethane. The dispersant preferably has reactive groups which are able to interact with the surface of the barium sulphate; particularly preferred dispersants are those which are able to endow the barium sulphate with a hydrophilic surface and which have reactive groups for coupling to or into polymers. The dispersion lends itself very well to incorporation into polymers such as acrylates, methacrylates, or particularly into hydrophobic polymers such as polycarbonate, or precursors thereof.

The outer ply comes from a rectangular blank folded lengthwise and the partition assembly comes from another blank that extends the transverse and cross partitions. The box takes shape from a third blank having wall panels and bottom flaps. The bottom flaps fold and glue together forming the bottom of the carrier. The partition assembly includes a transverse partition and at least one cross-partition. The partition assembly blank has a first body section, a second body section, and a handle section. The first and second body sections have a hinged connection at the handle section and form the transverse partition of the assembly. The first and second body sections further include at least one fold out section that defines the at least one cross-partition of the assembly.

Abstract: A device for preparing a very homogeneous and finely divided fine-ceramics mass from ceramic raw materials, liquids, aggregates, and similar materials, whereby the starting materials are finely ground, and liquid is added and later partly removed. The starting materials are ground dry or moist and all or some of the starting materials are first allowed to fall free in and through an upright container while being contacted with all or some of the liquid, which is injected in subject to turbulence, and then agglomerated into a granulate.
