Abstract: 1,140,919. Desulphurizing coke. MARATHON OIL CO. 25 May, 1966 [27 May, 1965], No. 23446/66. Heading C1A. Particulate coke is desulphurized by passing it through a zone to which O 2  and steam are supplied in amounts of 0À05-0À6 lbs of steam and 0À42-3À15 SCF of O 2  per lb of carbon in the coke and at rates such that the temperature of the zone is 1600-2500‹ F. Steam and air may be premixed and passed countercurrent to the coke, and may be fed in at various points; alternatively, air may pass countercurrent and steam co-current to the coke.

Abstract: 1,198,654. Feeding record tapes. INTERNATIONAL COMPUTERS Ltd. 21 Aug., 1968 [22 May, 1967], No. 23745/67. Heading G5R. The position of a selected endless tape loop 18 in a data store is controlled by the application of vacuum to opposite parts of the loop while maintaining the interior of the loop at atmospheric pressure. As shown, a selected loop 18 is transferred to a work cell 21, where it is circulated by a capstan 22 past a read/write head 23, by controlled air-pressure-switching at the ends of the various cells by pipes 24, 28 connected via respective electropneumatic valves (25, 29, Fig. 3, not shown) to a vacuum pump (26) or to atmosphere through a restrictor (27). Arrival of a loop is sensed by photo-cell 32 to successively reverse the pressure-switching so that the loop oscillates about a mean position, the same effect occurring in loop return by means of photo-cells 31 in the storage cells 17. Narrow slits 36 in the base are connected to atmosphere to prevent the loops collapsing, and to reduce wear the walls are made of glass and may receive ducted air at points of contact with the tape. The head 23 may be movable to change tracks and/or to permit transfer of a loop to and from the work cell should the loop have an internal magnetic coating to further reduce wear.

[Also in Group XXII] A spout 21 for a preferably metallic container is slidable within a sleeve 35 formed on a nozzle 20 which is secured on an upturned formation 12, 13, 14 bordering an opening in the wall of the container. A tamper-proof seal 22 and screwcap 23 with a gasket disc 23a are applied over the spout, which has a cut away portion, Fig. 11 (not shown), to facilitate pouring. A mounting rim of the nozzle contains a sealing gasket 28, preferably of the flowed-in type. The spout may be of a reversible type, Fig. 12 (not shown). Instead of being formed in one piece the nozzle may be formed of separate parts, Fig. 17, seamed together at 30a. In a modified form the spout is screw-threaded at its lower end to engage with internal threads formed in the neck of the nozzle, Fig. 14 (not shown). For small containers or those with a shallow recess in the head the nozzle may extend inwardly of the container, Fig. 16 (not shown). The opening is formed in the container during manufacture but the nozzle 20, spout 21, and cap 23 are applied after the container is filled, for which a clinching tool, Fig. 8, is used. This tool comprises an inverted cup member 41, providing a pressure pad 42, and swingably mounted jaws 44 round which an actuating bell 47 is mounted for vertical movement. As the bell 47 is forced down the jaws 44 are swung inwards so that projections 46 thereon engage a portion 26 of the nozzle 20 to clinch the nozzle on the formation 12, 13, 14 bordering the opening in the container.

Abstract: 1377579 Centrifugal classifiers J WESSEL 24 May 1972 24326/72 Headings B2H and B2P A centrifugal sifter, Figs. 1 and 2, comprises a rotor 2 which rotates in a housing 1 and is charged centrally with material to be sifted (arrow 24), and which contains material distributing passages 15 which lead the material outwardly to air-sifting zones 16 from which the fine material (arrow 24a), which is deflected inwardly again, passes to exhaust openings 18 arranged in the vicinity of the rotor periphery. The rotor 2 consists of circular discs 5, 6 with members 7 disposed therebetween and defining the distributing passages 15 and U-shaped exhaust passages 17 which lead sifting air and the fine material to the exhaust openings 18 which are provided in the lower disc 5 of the rotor and communicate with a collecting chamber 13 from which the air and the fine material are sucked by a fan (not shown) via a pipe 14 and a cyclone (not shown). The material to be sifted is introduced via a feed pipe 11 and a collar 10 through a central opening 9 in the upper disc 6 of the rotor. Rods 19 disposed upstream of the passages 15 serve to break up agglomerates of the material. The coarse material (arrow 24b) is thrown out of the sifting zones 16 by centrifugal force and led off through a hopper 1a against counter-flowing air (arrow 23) which effects further separation. In Fig. 3, the rotor 2 rotates about a horizontal axis 4'. The housing 1' is spiral shaped and is provided with an opening 26 which serves both as an inlet for sifting air and as an outlet for the coarse material. Further parttangential inlets for the sifting air are provided at 25. The air and fine material are discharged via the collecting chambers 13' and the pipe 14'.  In a modification, Fig. 5 (not shown), a baffle plate (27) adjustable about an axis (28) parallel to the axis of rotation of the rotor is disposed in each of the sifting zones (16') to maintain a uniform flow profile. In a further modification, Fig. 6 (not shown), a number of baffle plates (29, 30) are so disposed with their outer edges staggered. In a still further modification, Fig. 7, the exhaust openings 18' are disposed between limbs 31 of hairpin-shaped ribs. Two or more systems of distributing passages, sifting zones and exhaust openings may be provided in series in the axial direction in mirror-image relationship to each other, each system comprising an associated collecting chamber, and a material charging means common to all systems being provided on one side of the rotor and its overhung mounting on the other.
