Title: A method of separating sludgy liquids in centrifugal separators of the so-called clarifier type
IPC: C13B30/06
Filed: 1948-11-11
Abstract: An albuminous food is prepared from the spent beet used in sugar manufacture by pressing the beet to extract liquid, treating the liquid with acid to precipitate solids, separating sludge from the liquid in a gravity or centrifugal separator, centrifuging the sludge to obtain a concentrated sludge, and drying the concentrated sludge to form the food.ALSO:A method of treating sludgy liquids in a clarifier comprising a bowl, a disc-pack with distribution holes through which the liquid to be treated enters, a sludge space, and discharge outlets for the sludge consists in regulating the factors governing sludge accumulation so that the sludge fills the sludge space and the outer edges of the disc-pack.  To obtain the required consistency of sludge, a part or the whole of the sludge may be returned to the bowl inlet or to the sludge space.  The liquid from pressed spent sugar beet subsequently treated in a gravity or centrifugal separator may be the liquid treated in the clarifier.

Abstract: 1443162 Semi-conductor device OMRON TATEISI ELECTRONICS CO 20 June 1973 [20 June 1972 8 Nov 1972] 29356/73 Heading H1K A semi-conductor rectifier device of the type described in Specification 1,403,913, comprising a semi-conductor substrate separated from a tin oxide electrode by a thin insulating layer, is used for sensing temperature by connecting it in series with a reverse biasing voltage and a means, e.g. an ammeter, responsive to the reverse current of the device which varies with temperature. A modification of the device described in the above mentioned Specification, shown in Fig. 3(f) has the insulating layer, of silicon dioxide, 2 formed in a window in a thicker layer of silicon dioxide on to which the tin oxide electrode 3 extends, and the contact layers 4 and 9 formed by vapour deposition of nickel. The variation of reverse current with temperature can be increased by heat treating the device, e.g. at 150-400‹ C. for at least 5 minutes while it is subjected to a reverse bias of from 3 to 6 volts.

Gearwheels 11 are rotatably mounted on pins 10 attached to a pressure-loaded plate 8 which is fixed to rotatable shaft 13 carrying a lever 12, whereas gear-wheel 3 is attached to a driving, or output, shaft 3 and gear-wheel 4 is rotatably mounted on a fixed stub-shaft 5. In operation, plate 8 is rotated through a small angle in either direction by movement of lever 12 to displace gear-wheels 11 relative to gear-wheels 3, 4 and regulate the rate of flow of liquid between the meshing gear-teeth, the net rate of flow from one of said spaces to the other being dependent on the extent and direction of displacement of gear-wheels 11. Plate 8 has an extension 8<SP>1</SP> which slidably engages a recess 7 in cover 1<SP>1</SP> and is pressed against the side faces of the gear-wheels by the resultant pressure of liquid acting on surfaces 8<SP>11</SP>, 8<SP>111</SP>, the area of these surfaces being greater than the area of the plate exposed to the pressure of liquid between the meshing gear-teeth. Alternatively, pins 10 may be fixed in the housing, a pressure-loaded plate similar to plate 8 being lodged on one or both sides of the gear-wheels.

Abstract: 650,374. Feeding sheets. JACKSON, D. R. P., and MOLINS MACHINE CO., Ltd. Nov. 16, 1948, No. 29794. [Class 100 (i)] In mechanism for feeding sheets by means of a moving suction member 3 arranged beneath a pile of sheets 1, the sucker 3 is so arranged that part of its aperture projects beyond the edge of the pile of sheets when the sucker is in sheet-engaging position, and the size of the sucker is sufficient for that part of a sheet which is engaged to be drawn down into the aperture by flexure or distortion of the sheet, as shown in Fig. 4. On such distortion of the sheet being fed, the suction of the non- obturated part of the sucker 3 causes a flow of air past the sheet edge which assists in separating the sheet from the one above it. The sucker 3 is preferably of the rubber cup type, and the rear half thereof may be reinforced by an outer half-cup 18 (not shown) of metal which prevents flattening of the cup. The sheet-feeding mechanism may be as described in Specification 643,066. The sucker is fixed on a rod 4 drilled at 5 to provide an air passage connecting a passage 8 in a bar 6. The bar 6 supports the rod 4 and is fixed to a tube 7 adapted to reciprocate in a guide 9. A control valve 15 is located between the guide 9 and a suction pipe 16.
