Title: Nuclear reactors
IPC: G21C3/12
Filed: 1969-07-08
Abstract: 1306939 Fuel elements BRITISH NUCLEAR FUELS 11 Sept 1970 [8 July 1969] 34321/69 Heading G6C The fuel pins 3 of a fuel assembly each pass through a ring 7 of a spacer grid formed from a plurality of such rings brazed or welded to each other and to radial braces 4. Wear pads 6 having a length slightly greater than the width of the ring 7 are formed on the fuel cladding 3a where a fuel pin 3 passes through a ring 7. In the embodiment described, four wear pads 6 are used, but three or more than four may be used, as also may a single pad encircling the cladding. The cladding is preferably of a zirconium alloy and the wear pads are preferably of zirconium oxide. The material of which the wear pads are made is deposited by means of a conventional plasma spraying technique. The areas on which material is to be sprayed are prepared by grit blasting. Each area is defined by means of a mask. The material is plasmasprayed through the mask, a plurality of passes being made over the area defined by the mask. At least that area of the cladding on which material is sprayed is cooled during the spraying, e.g. by circulating a coolant such as water through the cladding. The wear pads are formed before the cladding is filled with fuel. As an alternative to zirconium oxide, zirconium may be used for the wear pads in which case zirconium hydride powder is fed to the plasma gun. The hydride dissociates at 750 C. into zirconium metal and hydrogen. Other suitable materials for the wear pads are zirconium nitride and other zirconium ceramic powders. Alternatively, metals and/or mixtures of metals and ceramics may be used. Although described with particular reference to a multi-pin type fuel assembly, the invention is also applicable to multi-plate type fuel assemblies, and to single pin or plate fuel elements.

Title: Multi-layer printed circuit board assemblies
IPC: H05K3/42
Filed: 1969-06-13
Abstract: 1310880 Multi-layer printed circuit boards MICROPONENT DEVELOPMENT Ltd 9 June 1970 [13 June 1969] 30014/69 Heading H1R A method of making a multi-layer printed circuit board comprises the steps of forming alternate insulating layers and conductor patterns on one or both sides of a printed circuit board, drilling holes at pre-selected positions, and lining the holes with metal to establish interconnections between the different layers of conductor patterns. The insulating material used is such that it will not smear on the drill, and thus will not prevent good interconnections being made between conductor patterns and the metal linings of the holes. Suitable insulating materials are heat-hardening resins such as cross-linked copolymers or catalyst hardened resins such as phenolic or epoxy resin. The holes may be lined with a readily solderable material such as tin, tin/lead alloys or gold underlaid by nickel. All metal layers may be copper, and may be deposited electrolessly, thickened electrolytically and masked and etched to produce the required patterns. After the final metal layer has been deposited on the walls of the holes and on the outermost layers, and solderable material deposited on the walls of the holes, the solderable material acts as an etch resist, protecting the walls of the holes, and after an appropriate mask has been applied to the rest of the metal layer, etching may be performed, using "Metex" if tin is used as the hole lining, ammonium persulphate if tin/lead alloys are used, and either of the above etchants or ferric chloride if gold is used.

Title: Diffractometry
IPC: G01N23/207
Filed: 1970-09-09
Abstract: 1329695 X-ray diffractometer J C NUTTER 9 Sept 1970 [3 Oct 1969] 48824/69 Heading GIA [ Also in Division H5] An X-ray diffractometer is designed, for analysis of a continuously moving specimen, in such a way that a plurality of the beams diffracted by the specimen may be detected without movement of the detector. In the arrangement of Fig. 1, the beam from tube target S is a continuous spectrum and is collimated at R and applied to a powder or alloy specimen M moving in a stream into the plane of the drawing. Diffracted radiation is detected via slit B by detector D. In order to differentiate between the proportions of the diffracted beam due to different constituents in the specimen, the detector circuit includes an array of pulse height analysers P after the linear amplifier C. By varying the analyser selected, the rate of pulses of the same amplitude in different amplitude bands may be measured, each band corresponding to a particular wavelength and thus lattice spacing, which in turn is characteristic of a particular constituent. If the chart recorder Q is synchronised with the analyser variation, a diffraction pattern will be traced out. Instead of single pulse height analysers, a multi channel device may be used to give a more complete pattern trace. In the arrangement of Fig. 2, Seemann-Bohlin focusing is used to avoid the need for a very small specimen. The specimen is curved with the detector D located at a point on the circle of sample curvature. Similar circuitry to Fig. 1 is used. Slit B may be dispensed with. The detector may be, for example, a silicon surface barrier device, or a lithium drifted silicon or germanium device. Fluorescent radiation may be prevented from interfering with the measurements by use of suitable filters

Abstract: 1348644 Cathode-ray tube circuits THORN ELECTRICAL INDUSTRIES Ltd 5 Nov 1971 [5 Nov 1970] 52760/70 Heading H4T A known convergence circuit, Fig. 2, in which a horizontal saw-tooth voltage (A, Fig. 1) produced across resistor 11 (in which the corresponding scanning current flows) causes a convergence current (B, Fig. 2) to flow in convergence coil 18 is modified, as shown in Fig. 3, by the addition of diode 19, transistor 20 and potentiometer 21, to which a horizontal fly-back pulse 22 is supplied, the modified circuit operating to equalize the magnitude of the current in coil 18 at the beginning and end of the horizontal scan period as shown by waveform C (Fig. 1).  In operation of Fig. 2 diode 12 commences to conduct at the centre of the scan (the zero crossing of the waveform A) and current flows through coil 18 via this diode and diode 19 until after the end of the scan interval when the waveform A rises positively and crosses the zero axis. Diode 12 is then cut-off and the back e.m.f. then maintains current flowing in coil 18 via diode 15, the current decaying exponentially until it reaches zero before the centre of the scan interval as shown by waveform B (Fig. 2). The magnitudes of the current at the beginning and end of this waveform are not equal and the modification of Fig. 3 operates to equalize these magnitudes by employing the line fly-back pulse 22 to render transistor 20 conducting so that the positive supply 23 cuts-off diode 19 and pulses coil 18 to augment the current through coil 18 during the fly-back interval (waveform D). The load on the horizontal fly-back circuit may be reduced by employing a further NPN transistor having its base connected to potentiometer 21, its emitter connected to the base of transistor 20 and its collector connected to the collector of transistor 20. The resistors 13 and 17 together with their associated parallel capacitors 14 and 16 respectively serve to set the biasing conditions of diodes 12 and 15 to predetermine the precise times at which they turn "on" and "off".

Filed: 1999-09-15
Abstract: A shock absorbing device for an electrical cable includes a resilient member attachable to two spaced-apart portions of the cable, so as to bias the spaced-apart portions toward one another and to impart an arcuate shape to the cable between the spaced apart portions. The device also includes a spacer member for location between the cable and the resilient member. The spacer member can ensure that the cable and the resilient member are maintained at a minimum distance, so that when tension is applied to the cable, the resilient member is deformed, thus producing a rising spring rate effect in the device.
