Title: Improvements in Method and Apparatus for Determining the Volumetric Mass or Density of a Gas
IPC: G06G7/48
Filed: 1966-11-30
Abstract: 1,152,013. Measuring density of a gas electrically. COMPAGNIE FRANCAISE THOMSON HOUSTON-HOTCHKISS BRANDT. Nov.30, 1966 [Dec.8, 1965], No.53722/66. Heading G1N. [Also in Division G4] The density of a gas in the region of its critical temperature is determined using the equation X = k(P) - F1(P). F2(T) where X is given by X =m/m o  P o /T o , M being the required density at temperature T and pressure P, and m o  being the density at temperature T o  and pressure P o . The functions k(P), F1(P and F2(T) are determined experimentally and are functions of the actual compressibility of the gas near its critical point. In the embodiment, the output signals from pressure and temperature measuring devices 1, 2 Figs.6, 7 (latter not shown), are fed respectively via amplifiers 3, 4 to function generators 5, 6, 7 (see also Division G4) in which the functions F2(T), F1(P) and k(P) are generated. The outputs of generators 5, 6 are then multiplied in a multiplier 8, whose output has the form F2(T), F1(P), and is fed to an amplifier 9 where it is combined with the output from the generator 7. The output from amplifier 9, is therefore a signal proportional to the required density. The above computing circuitry may also be used in the determination of the flow-rate of a gas in the region of its control temperature, as described in Specification 1,150,360.

Abstract: 1,191,659. Photographic processes and colour proofs. POLYCHROME CORP. Dec.14, 1967 [Dec.21, 1966], No. 56874/67. Heading G2C Coloured images are produced by image-wise exposing a light-sensitive material comprising an oleophilic support directly coated with a layer of a water-soluble hydrophilic polymer sensitized with a light-sensitive compound so that the layer hardens on exposure to light and developing to remove the unexposed areas and simultaneously or subsequently treating the material with a coloured lacquer which adheres only to the bared support to produce a coloured image thereon. The developer itself may contain the coloured lacquer and be a two phase emulsion containing colouring agent and resin in the organic phase and a surfactant in the aqueous phase or an aqueous developer may be used and a coloured lacquer be subsequently applied. If four such materials using transparent supports are image-wise exposed to four colour separation positives, developed and treated with a lacquer containing the appropriate yellow, cyan, magenta and black dyes; the four coloured images may be registered to produce a coloured proof for use in colour printing. The light-sensitizer may be a diazo resin, a diazonium compound, an azide, a quinone diazide, a bichromate or a nitro-aryl compound. The oleophilic support is preferably an oleophilic polymer.such as a polyester, a polycarbonate, a polyolefine, polyvinyl chloride, polyvinyl acetate, cellulose acetate or polyurethane. If the lacquer is non-drying or slow drying, the coloured image may be contacted with a receptor sheet to transfer the image. Colour proofs can also be made by this method. The light sensitive layer may be overcoated with a layer of a vinyl methacrylate/maleic acid copolymer and 2- hydroxy-4-methoxybenzophenone-5-sulphonic acid which is an ultraviolet light absorber. The overcoat improves the moisture-resistance of the light-sensitive layer. The tannable colloid may be polyacrylic acid, polyacrylamide, polyoxyethylene or polyvinylpyrrolidone.
