Abstract: 1317515 Conveyer belt systems D BRUHM 11 Nov 1971 [12 Nov 1970] 52461/71 Heading B8A A conveyer belt which has a curved planar conveying run, has its edge on the outside of the curve formed with a bead 10 which is engaged and guided by a series of pairs of guide rollers 12, 14. The axes of the rollers of each pair diverge towards the outside edge of the belt. The bead is secured to the belt by rivets 16. The pressure of the rollers 12, 14, acting on the beads causes the flanges of the bead to grip the edge of the belt. Thus due to friction forces thereby developed, the load on the rivets 16 is lessened. In a modification (Fig. 5), the bead is formed with notches 23, 24, which enable the bead to bend round the conical end rollers of the belt more easily. In a further modification (Figs. 7, 8, not shown), the bead is in the form of a series of separate blocks connected together by stud and socket fastenings. The belt engaging surface of the lower flange of each block is curved to follow the periphery of the conical end roller.

The layers of fibres form a laminated strip 22 which moves on belt 12, preferably supplied with a P.T.F.E. surface, to an adhesive station 20 wherein the strip is sprayed with an adhesive, e.g. methyl methacrylate. The strip then passes over a drier 24 to be wound on to a coiler 26 with a strip 112 of strip separating material, e.g. waxed paper. The shredders 16, 18, are each mounted on a turntable 74 and include a cutter head 50 with cutting edges 56, a coil 52 of metal foil, and a pair of feed rolls 54. The cutter co-operates with a shear bar 68 to form fibres 70a. Limit switches 88, 102 shut off the leading shredder when the carriage is moving in either direction and switches 90, 104 shut off the trailing shredders. Actuation of switches 92, 106 by nut (46), Fig. 1 (not shown), causes the shredders to rotate to alternate positions 50a, 84a whereupon the carriage reverses its direction and the belt 12 is advanced, in direction of arrow 32, a preset distance. The positions of the turntables, shredders, and distance of advance of the belt are adjustable and dependent upon the number of layers of fibres and the density of the strip 22. Cutting the strip into suitable lengths is effected for the production of storage battery plates (116), Fig. 7 (not shown). Nickel strip is used for positive plates and negative plates are coated and filled with a mixture of iron oxides and sulphur.

Title: Process and apparatus for supplying finely-divided solid fuels to a high-pressure gasification system
IPC: C10J3/30
Filed: 1965-12-16
Abstract: A process for the high-pressure gasification of powdered solid fuel (coal) is as described in the parent Specification, but the volatile liquid comprises 5 to 20% b.w. of the total mixture, the condensing and recycling of the separated condensate being thus rendered unnecessary and optional, the released vapours being passed with the coal under pressure to the gasifier.  An apparatus is described, see Figure (not shown), comprising one or more vertical chambers each having one or more horizontal outlet pipes at the bottom.  Plungers deliver plugs of fuel/hydrocarbon via the chambers to the pipes where a gate valve, operating in synchronism with the plungers, allows periodic access of the plugs to a section of the pipe heated by a water or steam jacket where vaporization occurs.  A rotatable helical blade disintegrates the fuel in the section, extracts it, and delivers it to a bunker communicating with the gasifier.  A specific example is described.
