Title: Improvements in or relating to nuclear reactor fuel elements
Inventor: GITTUS JOHN HENRY
IPC: G21C3/20
Filed: 1962-06-05
Abstract: In the manufacture of nuclear fuel elements, fuel particles are coated either before or after agglomeration into a porous unitary fuel element structure.  The coating may be metallic or ceramic, i.e. of carbide, nitride or oxide, and the particles or pores may be coated in any of several ways.  Metallic coating may be applied by deposition from the vapour, e.g. Mg, Al, Be and their alloys, or deposition from solution, sol or amalgam, the transfer being aided by heat or electrolysis.  Metal coatings e.g. of Zr, Nb, V, Ti and their alloys may be deposited by decomposition of their halides, and coatings of Ni, Mo, Fe, Co and their alloys may be deposited from their carbonyls. Metals and alloys can also be deposited from aqueous or organic solutions of their salts and other compounds, or from emulsion, sols and suspensions.  Once deposited the metallic coating may be transformed into oxide, carbide or nitride by exposure to a suitable oxidizing, nitriding or carburizing atmosphere.  In an example, wires of U / Mo alloy are cold drawn to make them straight and hard, and are then heated in nickel carbonyl gas to produce a nickel coating, they are then heated in molybdenum carbonyl gas to produce a molybdenum coating.  They are then coated with an adhesive and rolled in powdered stainless steel.  They are then heated to decompose the adhesive and sinter the stainless steel.  The wires so produced are then bundled together and sintered at their points of contact to form the desired fuel element.

[Class 38 (iv)] In a voltage regulator for an A.C. generator of the type in which the field of an exciter is supplied from the rectified output of the A.C. generator controlled by a self-magnetized transductor, and in which a compounding impedance varies the output voltage characteristic so that it rises with increased load; the transductor is supplied on the A.C. side from the same source as the regulator input, i.e. from a voltage that does not vary with the compounding characteristic. A current transformer 3 in the output line of attenuator 1 develops across the compounding impedance 4 a voltage which is subtracted from the output of a voltage transformer 2. A resultant input voltage to the regulator is tapped off an autotransformer 5, is rectified, and applied through impedances 8, 9, of different voltage/current characteristics to the opposing voltage-measuring windings 6, 7, on the first transductor, thereby controlling the current in the A.C. winding 12. This current, which is supplied by the transformer 5, is rectified at 14 and applied to D.C. winding 15 of a second transductor acting as a magnetic amplifier to control current from transformer 5 which is rectified at 18 and supplies the alternator exciter 19. In a modification the second transductor is omitted. It is also stated, that the transductor may be connected on the A.C. side to an independent voltage source.

Abstract: 695,925. Producing carbonyl metals. GENERAL ANILINE & FILM CORPORATION. Sept. 21, 1951 [Jan. 22, 1951], No. .22175/51. Classes 72 and 82(i) Carbonyl metal, of very small particle size and of uniform size distribution, is produced by thermally decomposing metal carbonyl in the free space of a reactor whilst subjecting the metal carbonyl to a sonic vibration. The term "sonic vibration" means one of the sound wave type irrespective of its frequency. The metal may be iron, cobalt, nickel or molybdenum. In the apparatus shown, the metal carbonyl vapours, e.g. iron penta carbonyl, enters from an evaporator through a line 5 into the reaction zone 4, the temperature of which is kept at 470-490‹F by heating coils 3. A 10 kW sonic generator 6, driven by carbon monoxide from a compressor 7 via a line 8, produces 3 kc vibrations which cause a 10-20‹F local rise in temperature in the zone 4. Some carbonyl metal is removed through an opening 14 in the bottom of the reactor and the remainder removed by the magnetic separator 11 from the carbon monoxide stream produced by the process and passing out at 12. Some of the carbon monoxide is combined with the throughput of the sonic generator and returned to the compressor 7 and the remainder is sent via a line 13 to, a gasholder.
