Title: A Process for the Production of Coated Carbidic or Oxidic Nuclear Fuel or Fertile Material Particles
IPC: G21C3/62
Filed: 1966-12-09
Abstract: 1,174,268. Nuclear fuel. NUKEM NUKLEAR - CHEMIE UND - METALLURGIE G.m.b.H. 9 Dec., 1966 [10 Dec., 1965], No. 55166/66. Heading G6C [Also in Division C7] Nuclear fuel comprising coated carbide or oxide particles is made by heating " green " particles containing nuclear fuel oxide with or without carbon to sinter or fuse the particles and to form the carbide if required and then coating with pyrolytic carbon in the same vessel. The particles may be heated at 1000-2550‹ C. under reduced or raised pressure. In an example particles containing UO 2 , ThO 2  and carbon are heated as a fluidized bed to 1700‹ C. to form the mixed carbide and then treated with methane to form a layer of pyrolytic carbon; by raising the temperature to 2000‹ C. the core contracts, leaving a gap between the core and the coating. Reference is also made to the use of a revolving tubular or barrel furnace. Reference has been directed by the Comptroller to Specifications 945,063, 943,719 and 878,927.

Abstract: 1,163,138. Finishing fabrics. CARL FREUDENBERG. 9 Dec., 1966 [10 Dec., 1965], No. 55328/66. Heading D1S. A continuous non-woven fabric 2 containing heat-shrinkable fibres is shrunk by dropping it down through a shrinkage zone 11, from the top of the zone, in which it is heated and thereby shrunk and drawing the shrunk fabric off from the base of the zone 11 at a substantially constant rate, the fabric 2 being fed towards the zone 11 in pulses so that it has intermittently varying degrees of slack on entry to the zone 11. As shown, the fabric 2 passes from a supply roll 1 around a guide roll 3 and between two intermeshing slatted drums 4 to provided the pulses of slack. Each drum 4 comprises at least two coaxial discs with slats spanning the distance therebetween. The fabric 2 drops into a heating chamber 5 with 'hot air or steam blown onto the fabric at the bottom the chamber, the hot air or steam rising so that shrinkage takes place in the zone 11. The shrunk fabric passes around guide rolls 6, 7, is smoothed by passing, under tension, over a smooth surface, e.g. a heated roll 8 and is wound on a roll 9. The fabric 2 is preferably a needled web containing polyester but may be a knitted or woven fabric. A needled fibrous web may shrink by at least 30% in each of the plane directions of the web.

Abstract: 1,249,358. Centrifugal separators. HOGANAS A.B. 20 Dec., 1968 [21 Dec., 1967], No. 60810/68. Heading B2P. In a method of fractionating granular or fibrous material, the material suspended in a primary gas stream is introduced centrally into a separator chamber, a rotary motion being imparted to the gas stream as or before it enters the chamber, and a secondary stream of gas rotating in the same direction as the primary stream is supplied to the separator chamber and combines with the primary stream. In the separator shown in Figs. 1 and 3, the primary gas stream containing the suspended material is fed to the separator chamber 4 via a pipe 1 and a guiding device 2 having an annular limiting guide plate 3. The device 2 comprises a guide chamber 13 provided with spiral guides 14 and a conical roof 12 which may be axially adjustable and which may be provided on its underside with spiral guides co-acting with the guides 14. The secondary gas stream is supplied through a helical gas duct 7 opening tangentially into the separator chamber, the secondary air passing through an annular gap 26 between the chamber wall 6 and a guide plate 5 mounted on an axially adjustable outlet pipe 8 through which the primary and secondary gas streams and fine material are discharged. The coarse material is discharged via an annular gap 27 between the guide plate 3 and the chamber wall 6 into a funnel 9.

Title: A cyclic vapour-phase process for the separation of n-paraffins from hydrocarbon feedstocks

Abstract: 1,209,369. Separating n-paraffins from hydrocarbon feedstock. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 24 Dec., 1968 [28 Dec., 1967], .No. 61240/68. Heading B1L. [Also in Division C5] A cyclic 6-stage 3-phase 3-bed molecular sieve vapour phase separation of n-paraffins from hydrocarbon feedstocks, e.g. kerosene, is achieved (by (a) passing the feed downward in succession through beds A and B (see Fig. 1a) until bed A is saturated with n-paraffins, bed B serving to ensure that the product effluent leaving bed B is entirely free from any n-paraffins, unadsorbed by bed A, and simultaneously passing eluent upward through saturated bed C to desorb n-paraffins therefrom; then (b) switching the feed so as to pass it downward through bed B where the n-paraffins continue to be separated by adsorption, while simultaneously passing eluent upward through bed A to purge it of unadsorbed feed and passing the purge mixture downward through bed C where the n-paraffins contained in the mixture are absorbed. These two stages comprise one phase of the 3-phase cycle, which is completed by the cyclic rotation of the functions of beds A, B and C. In general, the process is carried out isothermally at 93-427‹C. and at excess pressures of 0.35 kg/cm<SP>2</SP>. The molecular sieve is suitably a Type 5A synthetic zeolite, but natural zeolites may be employed. The eluent used preferably has 2 carbon atoms less or more in the molecule than either the lowest or highest constituent of the feed respectively; when the feed is kerosene, the preferred eluent is n-octane. It is desirable to operate the process with 4 beds, so that while 3 beds are on stream, the fourth is being reactivated and freed from carbonaceous deposits by first purging the bed with methane or natural gas at high temperature, purging again with nitrogen, and then burning the deposits by circulating a stream of nitrogen containing 1% oxygen. A flow sheet is provided (see Fig. 2, not shown) illustrating a 4-bed embodiment which is described.
