Abstract: 1,257,029. Cathode-ray tube displays. NATIONAL RESEARCH DEVELOPMENT CORP. 6 Dec., 1968 [6 Sept., 1967], No. 57637/68. Heading H4T. [Also in Division G1] Graphic display apparatus comprises an electrographic writing unit, 10 (see Specification 1,255,001, Division G1) which provides direct voltages representing x, y Cartesian coordinates of a point selected by a probe 23 in a frame of reference, 11, to a sampling circuit 32, where they are compared with first and. second ramp waveforms from an x and y scan generator 91, which circuit includes a coincidence detector and generates first and second tuning signals so as to vary the brightness of a visual display 36, a raster-scanned cathode-ray tube, at a point on its screen corresponding to the selected point in the frame of reference. The timing signals are fed to a digital computer 33 which transfers information stored therein to a regenerative store 34, which information is reproduced on the visual display 36 via an amplifier 85, pulse shaper, 87, and bright-up amplifier 92. The store may be a Williams tube wherein information is stored as variations in screen charge density, with raster scan from the generator 91 as is that of the visual display tube 36. The first and second tuning signals are in digital form the first being fed to a word address register (59), Fig. 4, not shown, and the second to a line address register (58) thus forming the two part address signal for the scanning spot. The visual display tube uses conventional 625- line television receiver circuits with interlaced scanning, line and frame synchronizing pulses being fed from the tuning unit 50, a block diagram of which is illustrated in Fig. 5 (not shown). In one embodiment of the apparatus only one field of the frame scan is fed from the regenerative store, the other being fed with information from a closed circuit television system 37. Such an arrangement may be used to display a time table on the TV-fed field whilst an observer selects with the probe a detail from the time table about which more information is required, the computer-fed field then retrieving the required information and feeding it to the regenerative store thence to the visual display tube. The Williams tube may be arranged to function as both the store and display tubes. It is also stated that the apparatus may be used without the computer for example as a teaching aid where the visual display reproduces on a large scale, or at multiple outlets, text and drawings produced at a single writing unit. Fig. 2 (not shown) illustrates the writing unit 10 and Fig. 3 (not shown) gives a block diagram of the sampling circuit 32. The regenerative store 34 may be a magnetic drum or videotape recorder.

Abstract: 1,265,974. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 4 Dec., 1969 [18 Dec., 1968], No. 60122/68. Addition to 1,195,206. Heading G6C. An agglomerate of nuclear fuel particles, each particle of which bears a fission product retentive coating, is formed by applying an overcoating of a powder composed of between 40 and 60 wt. per cent synthetic resin powder and between 60 and 40 wt. per cent graphite powder, vibrocompacting the overcoated particles into a mould cavity, and maintaining the vibration whilst zone heating the particles by causing a thermal front to pass through the cavity. The mould cavity may be formed by a blind hole in an elongate graphite member which constitutes a container for the agglomerate after moulding. In an example, the fuel had a kernel composed of UO 2 /C-10 in which the uranium contained 39 wt. per cent U-235, the entire uranium content of the coated particles being 21À1 wt. per cent. Fuel kernels of this composition were coated with several layers of pyrolytic carbon and silicon carbide in known manner. The mould cavity formed in a graphite member was cylindrical with spaced inner and outer cylindrical walls. A sleeve of polyethylene film was secured around the inner cylindrical wall and the overcoated particles were vibration filled into the annular cavity. An annular electric heating element was placed around the graphite member and moved upwardly throughout the length of the member which at the same time was vibrated. Loss of volume which occurred during the settling of the fuel particles was made good. Resin/ graphite bonds were formed between the compacted fuel particles which were agglomerated into a coherent mass, and the mass was heated to 800 C. in argon to carbonize the resin which had been cured during the zone heating process. The agglomerate was then heated in situ in the graphite at 1800 C. in vacuo. The presence of the polyethylene film, which carbonizes during heat treatment, allows the annular agglomerate to shrink radially without cracking longitudinally.

Abstract: 1294942 Television FERNSEH GmbH 9 Sept 1970 [22 Sept 1969] 43120/70 Heading H4F Most of a colour television signal is modulated on a carrier, e.g. for transmission or magnetic recording, but a part thereof which is devoid of picture information is replaced by the colour synchronizing signal or a signal derived therefrom and is directly transmitted or recorded without modulating the carrier, thereby enabling a colour sync. signal to be retrieved from the unmodulated part of the signal with a lower signal to noise ratio than that obtained by modulating and demodulating the sync. signal. The unmodulated derived signal may be substantially identical to the carrier as it would be when modulated by that part of the signal which is replaced. Thus in an F.M. system in which the blanking value occurs at 7 .77 mc/s., a colour burst at 4.43 mc/s. may be frequency multiplied by 7/4 and used to replace the blanking value at the end of the rear black shoulder, or the horizontal sync. pulses (7.16 mc/s.) may be replaced by a derived signal of 8/5 x 4.43 mc/s. Alternatively, the modulated colour sync. signal itself may be replaced by the unmodulated sync. signal, or a derivative. In the apparatus shown, a complete television signal 1 is frequency modulated at 2 and passed to a transmitter or recorder 4. As well as being frequency modulated, the colour burst is separated 5, changed in frequency 6, 7, delayed 19 and passed by a switch 3 (controlled'by pulses 15) to 4 in the blanking period between the burst and the start of the video signal. At the receiver the signals pass through a demodulator 9, low pass filter 17 and a delay 18 (equal to delay 19), to provide a complete signal including a "low fidelity" colour sync. signal and a blanking portion obtained by "demodulation" of the derived signal. A switch 13 passes the unmodulated part of the received signal (e.g. in synchronism with switch 3) to frequency changers 11, 12 to reconstitute a colour sync. signal of better S/N ratio which is inserted in the complete signal by a switch 14. A coarse coincidence circuit 22 ensures correct phasing of divider 11 by interrupting its operation until the two colour sync. signals are approximately in phase. The derived signal may have a frequency which falls below that corresponding to the sync. pulse tips but above the pass frequency of filter 17, so that the complete signal from 4 may be replayed or received by standard apparatus. It is said that types of modulation other than F.M. may be employed.

The fibres may be supplied via hopper 6. The fibres may be made of glass, or polypropylene, or may be a mixture, e.g. a mixture of curled fibres of 30-40 mm. length and straight fibres of 80-100 mm. length. The fluid may be water or air. When the fluid is aqueous, its viscosity may be increased by the addition of a thickening agent, or by the introduction of air by appropriate stroke adjustment of the paddles optionally with the addition of a chemical foaming agent. The thickening agent may be a magnetic powder which is subsequently recoverable for reuse. When air is used, a fluidised bed may be formed by jets of air and powder. Binder particles, e.g. latex particles or resin powder may be added to the aqueous dispersion in tank 1. The dispersion of the fibres in tank 1 may be assisted by means of a vibrator (not shown).
