  • Locating system
    Patent number: 5144312
    Abstract: A system for locating a transponder (10) to an accuracy of plus or minus about 10 m in an area about 5 km across includes a master station (12) and two slave stations (14, 16) at known positions. The transponder and the two slaves each incorporates an electronic flywheel circuit and means to bring it into synchronism with a synchronizing signal from the master station. After a preset delay the transponder then transmits a radio signal to be received by the slave stations and by the master station, the time of receipt of which is measured at each. From these times the location of the transponder (10) is determined by a computer (18).

  • Process for the destruction of alkylphosphate
    Patent number: 5114623
    Abstract: Alkyl phosphates, which may be dissolved in a hydrocarbon solvent can be destroyed in a two-stage process, the first stage involving hydrolysis with concentrated alkali to effect partial de-alkylation of the alkyl phosphate the second stage involving catalytic oxidation of the de-alkylated phosphate with hydrogen peroxide. This results in improved safety as oxidation takes place after much of the hydrocarbon has been removed at the first stage.

  • Metal pouring system
    Patent number: 5090603
    Abstract: A method and apparatus are described for controlling the rate of pouring of molten metal.

    Abstract: A rotary contactor (10) suitable for liquid/liquid extraction processes in a nuclear fuel reprocessing plant includes a rotor (14) with a contacting chamber (16) defined within it, the chamber being of annular shape with its radial width considerably less than its inner radius. Neutron absorbing material (22) inhibits neutron transmission between different parts of the contactor. Where the rotation axis is upright, liquids may be fed into the contactor via open-topped annular feed channels (30, 32) at the upper surface of the rotor (14). The chamber (16) includes a packing material (42) such as wire mesh, random or structured packing. The contactor also includes an arrangement to control the radial position of the liquid/liquid coalescing interface, or to control the radial position at which one of the liquids is taken off, which may be operated by gas pressure.

  • Phase-failure detectors responsive to unequal bending of bi-metal members
    Patent number: 5077626
    Abstract: Circuit breakers can be used to replace fuses in plant comprising centrifuge machines driven by small three-phase electric motors. The circuit breakers incorporate three bi-metal strips which bend due to the heat produced by current flow. Loss of current in one phase results in unequal bending of these trips. In one arrangement, a light-emitting diode 5 fitted to a first strip 2 produced light to pass through an aperture 8 in a plate 7 on the second strip 3 to fall on a photo-sensitive detector 6 on the third strip 4. Any unequal bending causes the light to be cut-off and the resulting signal can be used to trip the circuit breaker. In some cases the strips are the strips in the circuit breaker.
