Patent GB-638740-A (GB)
Title: Absorptiometer
IPC: G01J1/16
Filed: 1948-05-26
Abstract: 638,740. Photo-electric absorption meters. KINSEY, R. P., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. May 26, 1948, No. 14204. [Class 40 (iii)] In an instrument for continuous measurement of small changes in colour transparency or turbidity of a sample, particularly a continuously-running fluid, a beam of light is reflected from the mirror of a galvanometer through the sample under test to one photocell and directly to another. The two photocells form adjacent arms of a bridge circuit, the galvanometer being fed from an amplifier connected across the bridge output, the arrangement being such that a change of the light incident on the first photo-cell causes the galvo to tend to rebalance the bridge. A recording or indicating instrument is connected in series with the galvanometer and the galvanometer is shunted to avoid damage by the high current necessary for the recording instrument. The use of the instrument for measuring the optical density of glass, plastics, dyes, gases and smoke is mentioned.

Abstract: 752,699. Electric tests ; capacitors. ENGINEERING RESEARCH CORPORATION, Ltd. May 18, 1954 [June 11, 1953], No. 14577/54. Class 37. In apparatus for measuring the fluid contents of an irregular container by means of a measuring condenser having the fluid as its dielectric, and having one electrode shaped so that the surface level length of contact of the electrode with the fluid at every level is proportional to the surface area of the fluid at that level whereby a linear relationship is obtained between capacity and fluid quantity, is characterized in the provision of an electrostatic shield which eliminates the effects of stray capacities. The measuring condenser (Figs. 2, 3) comprises vertical, coaxial, cylindrical members 3, 4, the outer one, 3, being completely covered with conducting material but with apertures 7 to allow the fluid 8 to pass into the space between members 3, 4, and the inner one, 4, having a profiled conductive layer 13 on a rigid insulation member 29 co-operating with the electrode on member 3. A further conductive layer 6 covers substantially the entire remaining area of the member 29, with an edge portion 34 uniformly spaced from the profiled edge 35 of layer 13. In the complete circuit arrangement (Fig. 1) the voltage drop across the measuring condenser 2 is compared in a bridge network with that across a reference condenser 22, any unbalance voltage being amplified at 15 and fed to a servomotor 24 which rebalances the network by adjusting the voltage across the reference arms, and also drives an indicator 28, indicating the fluid content of the container 1.
