In Fig. 1, a parallel input S feeds logic networks 10, 11, 12, 16, parallel outputs G1, G2, G3 being strobed by relatively displaced clock trains C1, C2, C3 to gate parallel outputs E1, E2, E3 selectively into latches 13, 14, 15. The sets of latches 13, 14, 15 feed networks 11, 12; 10, 12; 10, 11 respectively, and they all feed network 16 which provides the parallel system output R. The G1 G2, G3 signals may be dispensed with, the C1, C2, C3 signals being applied directly to the latches. Parallel signals may be replaced by single signals. The relative displacement of the clock trains is sufficient to allow propagation through 13 and 11 between one pulse of C1 and the next of C2, &c. By connections not shown, and an auxiliary latch accompanying each latch, the latches can be connected in series as one or more shift registers for insertion of test patterns and removal of results during testing of part or all of the system. Figs. 7, 12 (not shown) show variations with 3 logic networks and respectively 2 and 4 latch sets. In the latter case, the auxiliary latches of one latch set can be the latches of another latch set. Shift register.-Fig. 9 shows one latch 37 of a shift register, with its auxiliary latch 42, each latch using a cross-coupled pair of AI-gates. One bit of a parallel input to the register comes via E, clocked at C, with one bit of parallel output at L. The input from the preceding stage of the register is at U, clocked at A. The output of latch 37 is clocked at B into the auxiliary latch 42 to feed the next stage of the register via V.

The metal may be an alloy of aluminium and the reinforced plastics may be epoxy resin reinforced with circumferentially extending glass or carbon fibres. Alternatively, the annular members 3A and 3D adjacent the end plates of the drum are made of carbon-fibre-reinforced plastics and the annular members 3B and 3C are made of glass-fibre-reinforced plastics. Where the drum is heated to produce a temperature gradient within the drum to facilitate the separation of gases, the annular members may have different thicknesses and some or all of them may have different lengths, Figs. 4 and 5 (not shown). In Fig. 7, where the drum part 2 is secured at the end to an end plate 4A and subjected to bending during rotation, the annular members 34A-34D, positioned adjacent the end plate, have a smaller axial dimension than that of the other members 34E, 34F. The end plate 4A may be formed with an open or closed annular groove, Figs. 8 and 9 (not shown), into which the end of the first drum part is fitted. A thickened annular member forming part of the second drum part is grooved on its inner end surface and bears against the first drum part and the outer peripheral surface of the end plate. In the gas centrifuge shown in Fig. 1, the composite drum I has hollow shafts 5A, 5B rotatably supported in bearings 10B, 10C mounted on frame members 7, 8, 14. Gaseous material to be separated, e.g. UF 6 , is fed into the drum via a conduit 12A, a chamber 11A and a feed conduit 6. The latter is rotatably supported in a bearing 10A and extends through the shaft 5A into the drum. A baffle disc 6A is mounted on the conduit 6 adjacent the drum end plate 4A. An electric motor 13 is provided within the frame member 8 to rotate the drum. A heater 15 is mounted on the frame member 7 adjacent the upper end of the drum. In operation, one separated gas component flows through the gap between the disc 6A and the end plate 4A and through the hollow shaft 5A into a chamber 11B from which it is discharged through a conduit 12B. The other gas component flows through the shaft 5B into a chamber 11C and is discharged through a conduit 12C.

Title: Production of n-type silicon bodies and silicon bodies so produced
IPC: C22F3/00
Filed: 1960-12-07
Abstract: 972, 549. Transmutation of elements. WESTERN ELECTRIC CO. Inc. Dec. 7, 1960 [Dec. 15, 1959], No. 42098/60. Drawings to Specification. Heading G6P. [Also in Division H1] Uniformly N type monocrystalline silicon is made by bombarding silicon, having an uncompensated impurity concentration less than 10 times that required, with thermal neutrons to convert Si 30  atoms to unstable Si 3i  atoms and thence to P 31  atoms, and subsequently annealing to remove bombardment damage. If the bombardment is directional the crystal may be slowly rotated, during bombardment, about one or more axis. An arrangement for producing simultaneous rotation about three mutually perpendicular axis is described (see Fig. 1, not shown). The concentration of P 31  atoms produced varies only Œ 5% with depth even when using a cube of silicon 25 cm. across, so that the principal cause of resistivity variation in the product is non-uniformity of the initial doping. Other reactions produced in the silicon by the thermal neutrons, for instance of transmutation of Si 28  atoms to the unstable Si 27  which decays to AI 27 , and of Si 30  to unstable Mg 27  which also decays to AI 27 , reduce the effective cross-section of the main reaction but do not affect the reproducibility of the process. Oxygen, which is normally present in silicon crystals, particularly those produced by crystal pulling is converted by the bombardment into different isotopes and to C 14  and F 19 . C 14  has a long half-life but is produced in insufficient quantities to be dangerous. The doping levels obtainable are increased if the starting material is doped with an excess of the isotope Si 30  by recrystallising from a melt containing the latter. A number of bombardment processes are described in detail and the effect of annealing for different periods and at different temperatures is discussed. Specification 932,427 is referred to.

Filed: 1961-11-28
Abstract: In the recovery of heat from organic reaction products in heat exchangers with production of steam the reaction product, after cooling to near the condensation temperature if desired, is compressed to raise the condensation temperature.  In the dehydrogenation of ethylbenzene to styrene at about one atmosphere the reaction effluent first heats incoming ethylbenzene-steam reaction mixture and is then cooled in a heat exchanger to about 125 DEG C. with production of steam at about 1,5 atmospheres pressure. The reaction effluent is then compressed to about 1,5 atmospheres and condensed with further production of steam.  In the dehydration of ethyl alcohol to ethylene the reaction effluent first heats the ethyl alcohol feed and is then compressed to about 1,5 atmospheres and steam and ethyl alcohol vapours are condensed with production of steam.

Filed: 1961-12-06
Abstract: 966,244. Light guides. FERRANTI Ltd. Dec. 4, 1962 [Dec. 6, 1961 ], No. 43676/61. Heading G2J. [Also in Division H1] The face plate of a cathode-ray tube is made from a bundle of fibres 4 of calcium magnesium silicate phosphor activated with cerium, the fibres being parallel to the axis of the tube and being bonded together by coatings 5 of glass having a lower refractive index than the fibres 4. In operation light passes through the fibres 4 with little dispersion, the coatings 5 enhancing the effect of total internal reflection at the fibre surfaces. The face plate is formed by pressing the fibres together while heated to cause their coatings of glass to fuse together, consequent distortion of the cross-section of the fibres further reducing light dispersion. A black face plate may be obtained by coating the inner surface with a layer of carbon or by coating the fibres or their coatings with black glass, which then forms the bonding material.
