Title: Time-division synchronous system for a plurality of individual synchronous telegraph circuits
IPC: H04L7/033
Filed: 1962-10-23
Abstract: 1,016,897. Telegraphy. KOKUSAI DENSHIN DENWA KABUSHIKI KAISHA. Oct. 23, 1962 [Oct. 23, 1961; April 12, 1962], No. 40097/62. Heading H4P.  A repeater in a telegraph system operates in time multiplex manner, whereby a plurality of input lines can be sampled. Received pulses on lines I1-I4, Fig. 3, are gated at the rate of 32 pulses/bit by p1-p4, respectively. The gated samples are combined to give a pulse train 5, Fig. 5 (not shown). This pulse train is itself sampled at the mid-point of the received bits by unit 4 which is fed by train 5. These sampling pulses are kept substantially in phase with the received bits. Unit 2 regenerates the pulses which are demultiplexed at 3 under control of timing pulses from 4. Unit 4 is described with reference to Fig. 4 (not shown). A pulse train 6 is derived from 5 by gating 5 with itself, delayed by T, and appears as the output of gate 9. Pulses 6 correspond to the positive going transitions in the received signals. Counter 19, which operates in multiplex manner, counts forwards for each pulse from gate 11 and backwards for each from gate 12. These gates are respectively enabled when the sampling pulses occur in advance of or later than the bit centres. In any channel, when sufficient pulses have been fed to counter 19 to fill it, i.e. 16, a carry pulse is generated which passes to counter 20. This also operates in time-division manner, and indicates the average changes in phase of the received transitions. By reversing the most significant bit of this 32-bit counter the binary output indicates the phase of the bit centre; this signal is fed to coincidence circuit 17. A local oscillator 13 provides pulses p0 which are divided down and counted at 15, the output being fed to comparator 16 and circuit 17. Comparator 16 provides the advance/retard signals to gates 11, 12, and circuit 17 the centre-sampling pulses. The extension of the system to an A.R.Q. arrangement is described with reference to Fig. 9.

Abstract: 901,786. Seaming non-metallic sheet material. EASTWOOD PLASTICS Ltd. Sept. 19, 1960 [Nov. 26, 1959], No. 40182/69. Class 42 (1). A method of forming the final closure seam between sheets or sheet portions 10, 11 of weldable material forming a hollow inflatable article comprises providing a " folded return strip " along the edge margin of one sheet or sheet portion 11; superimposing the other sheet or sheet portion 10 upon the sheet 11 so that edge of the sheet 10 and the " return strip " overlap; interposing a non-weldable barrier strip 16, in the angle formed by the " folded return strip," between the sheets 10, 11; and applying this assembly between electrodes of a welding-machine, the barrier strip 16 preventing the surfaces separated thereby from being welded together. In the embodiment shown in Fig. 1 the " return strip " is formed by the margin 14 of the sheet 11. After welding the sheet 11 is folded through 180 degrees and the strip 16 removed. In an alternative embodiment, Fig. 3, a separate strip 17 constitutes the " return strip " and the half strip 18 thereof may be welded to the sheet 11 before the strip 16 is inserted or may simply be positioned, one welding operation being sufficient to form the seam. In a further embodiment, Fig. 5, the strip 17 is set inwardly of the edges 12, 13 of the sheets 10, 11, respectively, and an edge-to-edge seam is formed in addition to the overlap seam. The method may be used for forming closure seams in hollow inflatable balls, hoops or liferafts, made of polyvinyl chloride, nylon or glass fibres. The strip 16 may be made of paper.

Abstract: 1302672 Boring pressure vessels T D WILLIAMSON Inc 31 Aug 1971 40671/71 Heading B3C Apparatus for tapping a pressure vessel comprises a boring bar 40, Figs. 1, 3, 4, and a lead screw 15 connected to the boring bar, means 18, 45, 46, for rotating the boring bar, and means 22, 27, 28, for rotating the lead screw, the boring bar rotating means being responsive to the load imposed on the boring cutter so as to vary the relative speed of rotation of the boring bar and the feed screw, and therefore the rate of feed. Lead screw 15 has a hexagonal end 15c, Fig. 4, which extends into a matching bore in a clutch sleeve 22, the latter being moved axially along the screw against a spring 23 by an hydraulic piston 34. Sleeve 22 is keyed to a worm-wheel 27 which is rotated by an hydraulic motor 31 through gearing 30, 29 and a worm 28. A worm wheel 45 is mounted on a drive sleeve 18 and is driven by an hydraulic motor 49 via gearing 48a, 48b, Fig. 1, and a worm 46, and the drive shaft 18 is keyed to a boring bar 40, Fig. 4, which bar is in screwed engagement with lead screw 15. A flywheel 47 is carried on worm shaft 46a, Fig. 1. Relative rotation between lead screw 15 and boring bar 40 causes axial movement of the latter and such relative movement is indicated on a counter 68, Fig. 1, which is driven from a differential 60, Fig. 4, which in turn is driven through a roller chain 63 by lead screw 15, and from drive sleeve 18 through gearing 17, 65. In operation, the apparatus is mounted on a valve (43), Fig. 5 (not shown), which is opened. The cutter (41) is moved to just above the pressure vessel (42) by rotating lead screw 15. Motors 31, 49 are adjusted so that the lead screw 15 and boring bar 40 rotate at the same speed. The rotational speed of screw 15 is now reduced by actuating a valve 55, Fig. 1, until the desired feed rate is obtained. As the cutter starts to bore, its rotational speed is reduced, as also is the feed rate. After the coupon has been cut from the workpiece the boring bar is retracted, the cutter is removed, and a plug is attached to the boring bar and then screwed into the hole in the workpiece.

Abstract: 1396767 Fuel elements GENERAL ELECTRICCO 15 Sept 1972 [30 Sept 1971] 42844/72 Heading G6C A nuclear fuel assembly has a central cluster of its fuel rods fuelled with initial Pu and is provided with a water tube extending through the cluster to increase the neutron moderation in the region of the Pu fuel and also to provide axial support for fuel rod spacers. The invention is described in connection with a boiling water reactor, the core of which comprises an array of spaced fuel assemblies submersed in lightwater moderator-coolant, each fuel assembly comprising a plurality of fuel rods 21 supported between upper and lower skeletonized tie plates 22, 23. Lateral support is provided by spacers 24. Each fuel rod 21 has end plugs 26, 27 formed with extensions supported in cavities 29, 31 in the tie plates 22, 23. Certain of the peripheral fuel rods are secured to the lower tie plate 23 by screw threaded end plugs 27<SP>1</SP> and to the upper tie plate 22 by retaining nuts 32. In this manner the upper and lower tie plates and the fuel rods are formed into a unitary structure. A thin-walled flow channel 33 is sized to form a sliding fit over the upper and lower tie plates. An inner cluster of fuel rods 21(1) contains initial Pu and is surrounded by fuel rods 21(2) containing initial enriched U fuel free of significant initial Pu. A fuel rod in a central position within the inner cluster is replaced by a water tube 41 similar to a fuel rod but containing no fuel and provided with apertures in its end plug extensions to permit a throughflow of water. The increased neutron moderation provided by the water results in a cooler neutron spectrum for the Pu-fuelled rods 21(1) to take advantage of the reduced capture-to-fission ratio in Pu-239 and Pu-241 and the reduced neutron capture in the fertile Pu-240. Advantageously, the Pu in rods 21(1) is mixed with natural or depleted U. Burnable poison such as Gd or Sm may be mixed with the Pu-fuel in rods 21(4) to control excess reactivity. Alternatively, the poison may be included in a plurality of the U-fuelled rods. In addition to the above-mentioned apertures, the tube 41 may be provided with coolant inlet holes 52 and outlet holes 53. The tube 41 is formed with radially extending, axially spaced fins or lugs (Figs. 11 and 12, not shown), by means of which the spacers 24 are retained in fixed axial position.
