Title: Nuclear fuel element
Inventor: KEALY WELLESLEY ASHE
IPC: G21C17/10
Filed: 1962-08-30
Abstract: 996,512. Temperature measurement by acoustic resonace; telephone instrumennts; resonators. UNITED KINGDOM ATOMIC ENERGY. Aug. 23, 1963 [Aug. 30, 19621, No. 33302/62. Addition to 967,473. Headings H4D, H4J and H4X. [Also in Division G6] The temperature of a nuclear fuel element is deduced from the resonant frequency of an acoustic resonator in thermal contact therewith. The resonator comprises a stainless steel tube 16 (Figs. 2 and 3) mounted on the stub 17 of a cut-away heat transfer fin 11 and retained by an insert 18 welded to adjacent fins apertures 26 (Fig. 3) being provided in tube 16 to admit ambient gas which may be the reactor coolant gas (e.g. carbon dioxide or helium). Each end of tube 16 communicates with a fine bore stainless steel tube 21 the other ends of which communicate with respective electro-acoustic transducers 22, 23 mounted on adjacent axial splitter fins 14, the latter being interconnected by braces 15 to which they are welded. Each transducer comprises a stainless steel casing 27 (Fig. 3) containing a diaphragm 32 carrying a magnetic armature 33, a gas-tight partition 28 including a magnetic annular portion 38 and a stainless steel spacer 39, a magnetic core 35 carrying a winding 34 and a ring permanent magnet 36 surrounding coil 34 and in contact with a magnetic base plate 37. The electrical leads 24 from the coil may be led out of the reactor or may terminate in breakable contacts on the fuel element which co-operate with similar contacts on adjacent elements or on the reactor structure. In operation, one (input) transducer is fed from an oscillator the frequency of which is varied until resonance occurs in tube 16 this being indicated by a peak in the output signal received by the other (output) transducer. To ensure that resonance occurs only in tube 16 the diameter of the fine bore tubes 21 is chosen such that standing waves are not set up in them. The position of the ends of tubes 21 within tube 16 may be adjusted for optimum impedance matching and both tubes 21 may extend from the source end of tube 16. Also, the position of tubes 21 within tube 16 may be adjusted so that acoustic transmission through the latter tube occurs at a harmonic of the fundamental frequency of the tube thus allowing the output transducer which is responsive to the harmonic frequency to share common electrical leads with the input transducer which is energized at the fundamental frequency, the output signals from the two transducers being separated by electrical filters. In another arrangement the tube 16 may form the frequency controlling element in a self-running oscillator in which regeneration is provided by arranging for the output transducer to provide a measure of amplification: e.g. the transducer in this case could be constituted by a carbon microphone.

Abstract: 1,019,345. Printed circuits. SOC. D'ELECTRONIQUE ET D'AUTOMATISME. Aug. 30, 1962 [Sept. 4, 1961], No. 33311/62. Heading H1R. A transfer plate for producing printed circuits comprises a rigid plate of insulating material having on one face thereof a printed circuit pattern the outer surface of which is formed of a metal having low adhesion to metal plated thereon to form the printed circuits (which are transferred on to a permanent base), said outer surface being flush with the face of the plate. As described a laminated plate comprises a layer of uncured epoxy glass and a Cu foil. The desired pattern is etched in the foil, using a photo-resist technique, and the resulting pattern is plated with hard Cr. The plate is then compressed in a heated press or die to make the plated pattern flush with the epoxy glass while hardening the latter. In use, the Cr pattern is plated with a layer of Cu which is transferred directly to a base in known manner, or is stripped from the Cr for subsequent bonding to a base; in the latter case, bridge pieces may be necessary to render the circuit integral.

Title: Improvements in the heat treatment of beryllium-aluminium alloys
IPC: C22C23/00
Filed: 1931-12-15
Abstract: Beryllium-aluminium alloys containing 6-94 per cent of aluminium are heat-treated by heating the alloy to or about the temperature at which the matrix crystals of the alloy normally become substantially equiaxed while maintaining a pressure on the alloy which is sufficiently high to prevent substantial sweating of the eutectic. The alloy may be heated in a gas such as helium at a pressure of approximately 150 lbs. per sq. in. to a temperature of 1250-1350 DEG F.  Before the heat treatment the alloy is heated to 1000-1050 DEG F., reduced by 25-50 per cent by a flat pressing operation, and then rolled at about the same temperature. After the heat treatment the alloy is cold-rolled and may be further rolled at a temperature not exceeding 1000 DEG  F.  In the Specification as open to inspection under Sect. 91 the treatment was applied to alloys in general, but this subject-matter does not appear in the Specification as accepted.
