Abstract: A dispersion of carbon black of a particle size 50-5000   in a non-aqueous medium which is liquid at fairly low temperatures, e.g. a plasticizer for rubber, is obtained by dispersing the particles as they emerge from the manufacturing plant in 25-100 times the weight of the particles of the liquid and subsequently concentrating mechanically, e.g. by centrifuging or filtering, to at least a pasty consistency.  The liquid used may be circulated along a closed circuit which includes homogenizers.  A composition for incorporation in tyre, sole, or belt rubber contains 45 parts black, 2 parts pine tan, and 3 parts stearic acid.ALSO:A dispersion of carbon black of particle size 50 to 5000  in a non-aqueous medium, which is capable of coating the particles of black, is made by dispersing particles of carbon black as they emerge from the plant for the manufacture of carbon black in a quantity of the medium corresponding to a weight between 25 and 100 that of the carbon black after which the material is concentrated in black by mechanical means, such as centrifuging and filtration, until a pasty consistency is obtained.  The liquid used is circulated along a closed circuit and the process completed in a series of homogenizers placed in cascade and the result may be a solid block.  The medium is selected from the binding agents of paints, inks and plasticisers of rubber.

The ice and surplus water are delivered by a shoot to a trough 38 fitted with a draining screen 39. The two parts of the casing are hinged about a common pivot 41, and the part 33 is adjustable by a screw 35, while the part 34 has a projection 42 engaged by an adjustable spring 43 to apply resilient pressure. The projection also serves to adjust a rheostat 44, which may be of the carbon disc type, for varying the speed of the driving motor according to the requirements of the press. The sides of the delivery casing part 34 are grooved as at 46 to produce ribs 47 on the briquettes, which facilitate ejection, and in order to prevent adherence of the briquettes to the pocket walls, water above freezing temperature is circulated from axial and radial inlet passages 53, 54, Fig. 3, through a tortuous passage 51 in the rotor wall, and issues into the surrounding casing. Owing to their curved shape the ice briquettes do not freeze together when stacked.
