IPC: G21C13/02
Filed: 1965-06-09
Abstract: 1,105,783. Moderator structures. UNITED KINGDOM ATOMIC ENERGY AUTHORITY 18 May, 1966, [9 June, 1965], No. 24460/65. Heading G6C. In a nuclear reactor core, the liquid moderator, heavy water, is contained in a calardria vessel having vertical fuel tubes. The vessel is divided into separate sections by inner walls, to facilitate variation of the moderator level in the sections and so to control the power generation distribution in the core. The different liquid levels in adjacent sections produce lateral hydraulic thrusts against the inner walls which are strengthened by vertical corrugations. The walls are thinner than would otherwise be necessary, resulting in a reduced neutron absorption. To allow for such an absorption the moderation in the wall vicinity is raised by increasing the lattice pitch of the fuel tubes thereby causing greater local moderation.

Title: Multiplex transmission method
IPC: H04J13/00
Filed: 1971-04-19
Abstract: 1348922 Multiplex systems NISSAN MOTOR CO Ltd and Y ISHII 19 April 1971 [18 Feb 1970 10 June 1970] 24482/71 Heading H4R In a multiplex transmission system carriers for the respective channels are produced by delaying a reference signal by predetermined respective amounts. Preferably the reference signal is an irregular, or pseudo irregular, pulse stream produced either by sampling a random noise signal, or as a maximum length linear shift register sequence signal. As described a reference signal is generated, either by a shift register 62, Fig. 7, connected to produce a maximum length sequence or by sampling a random noise signal, Fig. 12 (not shown), and used to modulate a clock pulse stream to produce an output 20, having the form shown in Fig. 8(c). The various carriers are generated by feeding the pulse stream to a flip-flop 76, Fig. 9, to regenerate the output of the shift register sequence generator, Fig. 8(d), and this signal is fed to a chain of flip-flops constituting a shift register delay device 80. In addition the input pulse stream, Fig. 8(c) is fed to a full-wave rectifier to regenerate the clock pulses, Fig. 8(a), which are used as shift pulses for the generator. The signals from the various tappings of the delay device may be used directly as carriers or they may be multiplied together, as in 88, Fig. 9, to allow the generation of (2n-1) carriers with only (n-1) shift register stages 80. A bias circuit 94 is provided on the output of the multipliers 88 to restore the D.C. level to a suitable value for use in the modulators. The output 20, i.e. the pulse stream, Fig. 8(c), is fed to the receiver to allow generation of identical carriers therein, for demodulation by a multiplication and smoothing process when all signals on non-correlated carriers, i.e. carriers having different delays, will disappear.

Patent GB-990367-A (GB)
Title: Improvements in or relating to semi-automatic radar tracking devices
IPC: G06F3/041
Filed: 1961-07-06
Abstract: 990,367. Radar. SOC. NORVELLE D'ELECTRONIQUE ET DE LA RADIO INDUSTRIE. July 6, 1961 [July 27, 1960], No. 24520/61. Heading H4D. Relates to a rate-aided manual tracking system for an azimuth scanning pulse radar in which echoes from a target within an adjustable two-dimensional window area are selected by a corresponding window gate, the window area being indicated on a P.P.I. display by a corresponding adjustable window marker. According to the present invention the position and rate of displacement of the window marker are controlled to maintain the target echo in the centre of the window marker by means of a control panel 1 of the same shape as the window marker, the control panel being subdivided into a plurality of segments each containing a pushbutton. In operation, if the target echo moves from the centre of the window marker the operator actuates the push-button corresponding to the new (displaced) position of the echo to generate the required marker control signals. As described, radial and angular components (polar co-ordinates d, #) of the control signals are generated but it is stated that orthogonal (cartesian) components may be used. As shown, when a push-button, e.g. 3, is depressed it triggers on a pulse generator 9 and sets up in a corresponding one, 140, of a plurality of digital registers 14 a number n proportional to the radial displacement of the push-button 3 from the centre of the control panel. When the number of output pulses from the pulse generator 9 as determined by a counter 11 is equal to the number n set in the register 140, the register produces an output which is applied through an OR gate 15 to stop the pulse generator 9 and counter 11. The output from the pulse generator 9 is also applied (1) through the counter 11 and a selector switch 16 to a distance error counter 6 to give a radial position error signal ep the sign of which is controlled by the push-button 3 via a connection 7 and the scale of the signal ep being determined by the setting of the switch 16, and (2) to a divider 12 where the pulse train is divided by the time interval # that has elapsed since any previous corrective action to give a radial velocity error signal ev = #p/#, the value of # being determined by a timing circuit 17 controlled by the push-button. The outputs ev and ep from the divider 12 and counter 6 are then combined in an integrator 13b to give the signal which controls the radial position of the window marker; as shown the output ev from the divider 12 is applied to the integrator 13b via a velocity storage counter 13 and an AND gate 13a coupled to the timing circuit 17. The angular position control signal is generated in a similar manner by the corresponding units 61, 91, 111, 144<SP>1</SP>, 20, 21a and 21b. Specification 947,378 is referred to.

Title: Improved method and device for producing noiseless sound records
IPC: G11B7/00
Filed: 1939-08-26
Abstract: 523,045. Sound recording and reproducing. PHILIPS LAMPS, LTD. Aug. 26, 1939, No. 24612. Convention date, Aug. 29, 1938. [Class 40 (ii)] In a " noiseless sound recording system in which the zero line of the recorded wave is shifted step-wise with changes in volume, the displacement of the zero line is effected according to a sine curve. The displacement of the zero occurs whenever the volume of recorded sound exceeds or becomes less than predetermined levels. The output from a microphone 1, Fig. 1, is passed through amplifiers 2, 3 to an oscillograph 4 and also to a rectifier 14 whose output passes to series connected relays 16. When the sound volume and thus the rectified output exceeds a predetermined value the contact 17 closes to allow current to flow through the oscillograph from a battery 20 through resistance 19 and an inductance 22 shunted by a condenser 21. The combination of condenser and inductance causes the increasing current, and so also the displacement of the oscillograph to follow a sine law. Further increase of sound intensity beyond another' predetermined level causes closing of the contact 18 so as to short circuit the resistance 19 and cause a further increase in the direct current flowing through the oscillograph from the battery 20. The invention may be applied to variable density, variable width photographic records or to mechanically produced records.

Abstract: 772,833. Measuring velocity of shock waves. TITTERTON, E. W. Sept. 20, 1948 [Sept. 30, 1947], No. 24637/48. Class 118 (2). [Also in Group XXXVI] A system for measuring the velocity of shockwaves, such as detonation waves in explosives, comprises a plurality of circuit-closing devices 20, 21 . . . 22 operated by the passage of the shock-wave (see Group XXXVI), and each arranged to discharge an associated charged condenser 13, 14 . . . 15 into a common conductor connected to a cathode-ray oscilloscope 26, via a damping resistor 23 and co-axial cable 25. The composite pulse displayed enables the speed of the shock wave to be determined. The individual rapid discharges build up a charge on condenser 12 to produce a pulse as shown in Fig. 4. Ideally, six devices 20, 21 . . . would give a trace as at 50, or, if closed simultaneously, as at 51. In practice, however, each discharge has a shape as at 52 and simultaneous closure of the devices produces a trace as at 53. The occurrence of successive closing gives a trace as at 54, the height of which can be observed or recorded photographically. The charging resistors 17, 18 . . . 19 are large enough to provide a long time constant with their associated condensers 13, 14 . . . 15, whereby multiple switch closings, or shorting of leads, produces little or no effect in the trace. The cathode-ray oscilloscope may show fiducial timing pulses as indicated in Fig. 1 from a suitable pulse generator (not shown). The height of the output trace is a somewhat non-linear function of the number of switches closed within the time constant of condenser 12 and resistor 24. A modification (Fig. 3, not shown) to avoid this non-linearity comprises alternate positive and negative potentials on the condensers such that instead of a cumulative pulse a series of small pulses alternately up and down, as at 55 in Fig. 4, are produced.
