Abstract: 563,792. Treating rice &c. STEEL BROS. & CO., Ltd., and HOLL, F. M. March 29, 1943, No. 5033. [Class 58] A process for treating rice and other cereals consists in cleaning the grain and transferring it to a vessel in which it is first steeped in water which is kept in a state of circulation and then steamed at atmospheric pressure, the treated grain then being transferred to a drying machine. The circulation of the water may be effected by steam jet pumps which also serve to maintain the steeping water at a constant temperature. Cowls may be arranged above the vessel to collect steam and vapour during the steeping process and such steam may be used to maintain the temperature of the grain during its transfer to the drying machine. In the construction shown, the grain from the washers 2 is transferred to the steeping and steaming vessels 8, and is subsequently fed by a jacketed conveyer 9 and elevator 9a to a drying device 11. Waste circulating water from the vessels passes to a heating tank 3 whence it is fed by a pump 6 to a hot well 4. A further pump 6a delivers the heated water back to the vessels,

[Classes 96 and 140] [Also in Groups III and IX] Glass fibres are bonded together by a colloidal suspension of bentonite in which the particles do not exceed 3000 Š in diameter. A suspension of bentonite in distilled water is allowed to settle to remove coarse particles and is then treated in a high-speed centrifuge. The gel deposited in the centrifuge (containing 10 per cent. of solids) consists of particles of under 3000 Š diameter, particles of about 1500 Š predominating. The liquid (containing 1 per cent. of solids) consists of particles smaller than 500 Š in diameter, and may be used as a preliminary size to bind the glass fibres loosely together. The gel is then applied to the mat to form a paper-like sheet, band or tape with the fibres arranged at random or in parallel relation. The gel may also be used for preliminary sizing. The gel may be worked into the fibres by rubbing between two surfaces. Tape having a thickness of 2 mils comprising parallel glass fibres of 0.2 mils diameter is described. A number of layers may be superposed which are moist and adhered by pressure. The products are suitable for electric insulation and may be impregnated with hexachlor-diphenyl trichlorbenzene or chlorinated naphthalene.
