Title: Improvements in or relating to methods of and apparatus for refining suspensions of natural, synthetic or regenerated fibres
IPC: D21B1/12
Filed: 1964-08-04
Abstract: A suspension of natural, synthetic or regenerated fibres is refined by compressing it in a space, one wall at least of which retains the fibres thereon but allows the passage therethrough of a large part of the suspension liquid, and subjecting the retained fibre mass to a rubbing action and then to decompression, the steps of compression, rubbing and decompression being performed cyclically and automatically.  In one embodiment the suspension is fed into one or more work areas around a rotating drum, each area having a reciprocating grill on which, as the grill moves towards the drum, the fibre mass is deposited and then rubbed by the drum. The return of the grill causes the suspension liquid to pass back through the grill to bring the rubbed fibre mass back into suspension.  Reflux areas within the grills are linked by tubing, the operation of the grills being staggered.  In another embodiment, Fig. 7 (not shown), the suspension is introduced into work areas formed between flexible vanes mounted on either a stator or a rotor, the work areas being varied in size as the vanes move relative to one or more undulating grills fixed to the other member.  The grills may have various shapes, Figs. 8 and 9 (not shown).  Alternatively, Fig. 10 (not shown), there is a fixed disc and a rotating disc mounted in juxtaposition, one disc having an undulating grill and the other the flexible vanes.  Other embodiments concerning disc and conical mills are described (see Division B2).

Title: Improvements in or relating to processes for the production of high purity monocrystalline silicon
Inventor: SIRTL ERHARD
IPC: C30B25/02
Filed: 1963-08-08
Abstract: <PICT:1016578/C1/1> Monocrystalline Si is produced by initially passing a gas mixture of H2, hydrogen halide and a silicon-halogen compound, over a heated Si carrier and then reducing the proportion of hydrogen halide so that Si is deposited on the carrier.  The initial gas mixture removes the oxide film and surface layers of Si from the carrier, thus exposing the undisturbed Si lattice. Sufficient hydrogen halide is maintained during deposition to prevent impurities, e.g. boron, being deposited.  The carrier may also be pretreated with H2 or H2 + hydrogen halide.  Si rod 2 is mounted between electrodes 13, e.g. of graphite, in quartz vessel 1, and heated by an electric current flowing through it to 1150 DEG  C.  H2 from 9 and HCl from 10 are passed through trap 23 to freeze out water vapour, and mixed with silicon-chlorine compound evaporating from 8. This cleaning mixture, containing up to 30% HCl with up to 5% SiHCl3 or 2% SiCl4, flows through vessel 1 at 50-100 1/h.  The HCl feed is then reduced, the temperature of the carrier may be increased, and the flow of gas increased to 500 1/h. SiHBr3 or SiBr4 may also be used.  Reference has been directed by the Comptroller to Specifications 809,280, 914,042 and 926,807.

Patent GB-835962-A (GB)
Title: Recovery of acrylonitrile
Inventor: HADLEY DAVID JAMES
Filed: 1957-10-10
Abstract: Hydrogen cyanide is removed from a dilute aqueous solution of acrylonitrile containing also an aliphatic aldehyde and hydrogen cyanide by distilling the solution in a first still to take off overhead a fraction containing acrylonitrile, hydrogen cyanide, aldehyde and water and feeding this fraction without condensation to a second still which is operated continuously under such conditions that the hydrogen cyanide is removed in an overhead fraction and acrylonitrile is recovered as the base product.  The process is preferably used for the separation of hydrogen cyanide from acrylonitrile obtained by the reaction of acrolein with ammonia and molecular oxygen at elevated temperature in the presence of a catalyst, e.g. molybdic oxide.  Preferably a vapour divider is provided at the head of the first still to enable a proportion of the overhead fraction to be condensed and returned to the still as reflux.  The second still is advantageously operated under reduced pressure.  It is desirable to operate the distillations in the presence of a conventional polymerisation inhibitor.ALSO:Acrylonitrile is produced by passing a mixture of acrolein, ammonia and air in vapour phase over a molybdic oxide catalyst. The gas leaving the reactor containing acrylonitrile, acrolein and hydrogen cyanide is scrubbed first with dilute sulphuric acid to remove ammonia and then with water.  The acrylonitrile is separated from the resulting mixture by a process of distillation (see Group III).
