Title: Process and apparatus for measuring the relative rates of flow of each phase of a two-phase fluid flow comprising a liquid and a gas
IPC: G01F5/00
Filed: 1976-09-17
Abstract: 1524489 Measuring flow-rate of two-phase -fluids BATTELLE DEVELOPMENT CORP 17 Sept 1976 [19 Sept 1975] 38699/76 Headings G1N and G1R The flow-rates of liquid and gas components of a composite fluid 1 are measured by isolating successive volumes V o  of the fluid, expanding or compressing them until a predetermined volume or pressure is reached and measuring the corresponding change in pressure #P or volume #V. From this data and a count of the number of volumes isolated per unit time the flow-rates of each component are determined. In a first embodiment the rotor 23 of a vanetype pump 11 has its axis of rotation 22 displaced laterally from the centre 17 of the chamber 16 so that between inlet 12 and outlet 13 the volume of cells 27 gradually increases. Signals from pressure sensors 28a, 28b in cells 27a, 27b are fed to a subtractor 30 which provides a signal #P to function generator 31. The generator 31 also receives signals P o  directly from sensor 28a and n from a tachometer 39 and stores volume signals V o  and #V and other parameters, e.g. density. Generator outputs are fed to indicators 32, 33 for flow-rate and to integrators 34, 35 for total flow of each component. The rotor of the pump is coupled to a brake or motor 37 controlled by a regulator 38 so that disturbance to the flow of fluid by the pump is minimized. In a second embodiment Fig. 5 (not shown) the subtractor is replaced by a circuit (41) which detects at which one of the pressure sensors a predetermined change of pressure #P has taken place and feeds the volume of the cellule at this sensor to the function generator. In a third embodiment, Fig. 7 (not shown), the axis of the rotor is displaced vertically below the axis of the chamber so that expansion is followed by compression, and in a fourth embodiment vane pump (Fig. 7) is replaced by three eccentric screw pumps in series.

Abstract: 1,168,074. Luminescent materials. DAI NIPPON TORYO K.K. 31 Aug., 1966 [31 Aug., 1965; 12 July, 1966], No. 38958/66. Heading C4S. Rare earth oxide phosphor particles have a surface coating of an acidic oxide of B, Al, Ti, V, Ga, Ge, As, Nb, Mo, Sn, Sb, Ta or W. The coating may be applied by mixing preferably in a liquid medium the phosphor and the oxide or a compound which on heating forms the oxide, e.g. hydroxides, carbonates, sulphides and NH 4  oxyacidates. The mixture is heated causing the oxide to melt; some of the oxide may diffuse on to the surface of the phosphor particle, reacting to form an adhering intermediate layer. The particles may be coated by mixing the oxide suspended in an aqueous or non-aqueous dispersion and the particles and then drying. An hydroxide can first be deposited by adding a solution of the salt to a phosphor suspension and adjusting the pH value, then heating to convert the hydroxide to oxide. A further method is to add the oxide to a slurry comprising an aqueous phosphor suspension and PVA. Y 2 O 3  : Eu is coated with Wo 3 , B2O 3  or Ga 2 O 3  by mixing and heating; formation of Y tungstate and Y gallate are referred to. Gd 2 O 3  : Eu is coated with MoO 3  by mixing with water to form a paste and then drying. Gd 2 O 3  : Eu is coated with As 2 O 3  by mixing with water and PVA. Slurries containing the coated particles were prepared using PVA and NH4 bicromate sensitizer for photo-printing colour TV screens.
