Title: Improvements in or relating to time signal corrected timekeeping devices
IPC: G04G7/02
Filed: 1963-08-28
Abstract: 1,033,884. Time-signal corrected clock. KOKUSAI DENKI KABUSHIKI KAISHA. Aug.28, 1963 [Aug.31, 1962(2)], No. 34078/63. Heading G3T. Comprises a first transistor oscillator 1 controlled by an electromechanical resonator 2 and providing an output at a first frequency f 1 , a second transistor oscillator 3 which is self-excited at a second frequency f 2 , locked to the oscillator 1 and coupled thereto by an impedance coupling 4. The oscillator 3 controls driving means 5 for the hour, minute, and seconds hands. A gauged changeover switch 9 connects as shown with a low frequency transistor amplifier 6 forming part of a ratio receiver for the correct time signals, and a diode/ transistor rectifying and amplifying circuit 7 the output of which is fed to a relay 8 which actuates means such as a plunger and cam whereby the hands are corrected. For normal running the switch 9 is positioned to the left, and just prior to the receipt of the time signal is moved to the position shown. Resonator 2 is thus connected between the amplifiers 6 and 7 which are energized by a source 10. If the resonator frequency is selected to coincide with the time signal frequency or to have a narrow bandwidth on each side of it, the resonator acts as a selective filter to cause operation of the relay 8. During the correction period, the oscillator 1 ceases and the hands are controlled only by the oscillator 3. Any resulting inaccurracy during this period is negligible. Instead of using the same frequency for both functions of the resonator 2, i.e. its use to control the oscillator 1 and to serve as an interstage selective filter between the circuits 6 and 7, a harmonic or other frequency due to weak oscillation modes may control the oscillator whilst the fundamental frequency may be used in the filter position. A. driving means for the hands comprises a balance 13, Fig. 4 (not shown) impulsed by an arm 12 through an electromagnet 11 which receives a half-wave rectified current from oscillator 3, the balance being repelled on the reverse swing by a magnet 16 thereon co-operating with a stationary magnet 17; or the parts 11, 12 may be replaced by a coil 19 co-operating with a magnet 18 on the balance, Fig. 5, (not shown).

Title: Process for the separation of plutonium
IPC: G21C19/46
Filed: 1945-12-18
Abstract: 897,261. Plutonium separation. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Dec. 18, 1945 [Dec. 30, 1944], No. 34353/45. Class 39(4). An aqueous solution containing plutonium is purified from radioactive elements by contacting the solution with a finely-divided water-insoluble metal iodate, the pH of the solution being 2 or less and the plutonium being in the hexavalent state. A supernatant solution of plutonyl iodate is formed. The solution treated may be prepared using nitric, hydrochloric, hydriodic, sulphuric, or iodic acid, and the plutonium may be oxidised to the hexavalent state with an alkali metal bismuthate, permanganate, or dichromate, or lead dioxide. The metal iodate may be precipitated in the plutonium solution by adding metal ions (for example thorium, cerium, or zirconyl ions) followed by iodate ions; alternatively preformed solid iodate may be added or the solution may be passed through a column of the iodate. As a preliminary step, a solution of neutron-irradiated uranium containing plutonium and fission products in an inorganic acid may be formed having a pH of 2 or less and the plutonium in the tetravalent state; this solution is treated with iodate ions to precipitate plutonous iodate (if desired together with a carrier iodate precipitate) which is separated before a substantial amount of uranyl iodate precipitates; the plutonous iodate is dissolved in acid, oxidised to the hexavalent state and purified in accordance with the invention. The plutonyl iodate formed may be reduced by hydrogen peroxide to the plutonous state and the cycle repeated. If neptunium is present, it is purified in the same way as plutonium.
