    Abstract: 1,098,496. Extrusion granulating machines. BADISCHE ANILIN- & SODA-FABRIK A.G. April 28, 1965 [April 29, 1964], No. 17810/65. Heading B5A. An extrusion granulating machine, particularly intended for granulating thermoplastics, comprises a screw 1 whose flight 3 is provided with a hollow ground cutting edge 3a, the screw combining the functions of cutting the extrudate 4 and conveying the granulate towards outlet 8, the latter function being assisted by liquid coolant which enters by inlet 2a and is carried by the screw into contact with the die face from a trough 2b. Additionally a gaseous coolant may be used. Die head 5 is provided with band heaters 6 and a ceramic plate 7 thermally insulates the head 5 from chamber 2. Screw 1 may have one or more flights 3, be tapered, and in any case is arranged to be easily replaceable. In a second embodiment, Fig. 3 (not shown), several rows of extrusion orifices are provided and in the embodiment of Fig. 4 (not reproduced), several screws with or without a common drive are used. The flights of these screws may overlap one another.

    Abstract: Concrete compositions are prepared from cement, water, an optional aggregate and particles of expanded styrene polymers whose surfaces are coated with an organosiloxanol of formula where n is an integer from 1-250, R is a C1-C6 alkyl or alkenyl group or an aryl group. The styrene may be copolymerized with acrylonitrile, acrylic or methacrylic esters of C1-C8 alcohols, N-vinyl compounds, e.g. N-vinyl carbazol and divinylbenzene. Aggregates specified are sand, pumice, vermiculite and asbestos.
