Title: Fluid measurement
IPC: G01N29/032
Filed: 1972-05-11
Abstract: 1447481 Ultrasonic inspection WOLFSON LABORATORY FOR THE BIOLOGY OF INDUSTRY and D R CHILVERS 10 Aug 1973 [11 May 1972] 22086/72 Heading H4D The ratio of inclusions to fluid for a test medium is determined by obtaining a first output signal dependent on the magnitude of an ultrasonic signal which has travelled a predetermined distance through the medium, and comparing the first signal with a second output signal similarly obtained using a medium of known inclusion-to-fluid ratio. In the embodiments described the ultrasonic signal is pulsed. The signal received after travel through the test medium is applied to a voltmeter, oscilloscope, recorder, alarm device, or industrial process control system. The medium may be a liquid or gas and the inclusions may be liquid, solid, or gas bubbles. To compensate for the effects of the presence of bubbles when it is desired to sense solid inclusions, two ultrasonic transmission paths are used and a signal independent of bubble presence but representing the solid inclusion ratio is then derived from the two received ultrasonic signals. The embodiments can be used to sense the position of fluid interfaces.

Abstract: 636,234. Photographic emulsions. KODAK, Ltd. Aug. 8, 1947, No. 22120. Convention date, Nov. 17, 1939. [Class 98 (ii)] A highly-sensitive developing-out silver halide emulsion is prepared by the incorporation, at any stage in its preparation, of a gold compound which gives gold ions in aqueous media in an amount less than 0.15 per cent by mols. of the silver halide and a metal or ammonium thiocyanate. An amount between 0.003 and 0.005 per cent may be employed. The thiocyanate may be used in a concentration of not mpre than 2 per cent by mols. of the silver halide, and its concentration may be at least four times (generally from five to ten times) the concentration of the gold. The emulsion is preferably digested in presence of the thiocyanate. Sodium, potassium, calcium, ammonium, or cadmium thiocyanate may be used, and water-insoluble thiocyanates may be added to the emulsions as a gelatin dispersion. Larger amounts of thiocyanate may be used if added before washing. The gold compound may be a simple or complex halide (e.g. auric chloride or potassium auric chloride), an aurous compound, auric sulphate, an alkali metal aurous thiosulphate or sulphite, or the complex salt from auric chloride and thiourea. Potassium aurocyanide is unsuitable. The preparation of an emulsion is described. Inert gelatin may be used, and contrast may be increased by the incorporation of an alkali metal thiosulphate.

Abstract: 1,189,981. Selsyn machines. E. HOWBROOK. 4 May, 1967 [19 May, 1966], No. 22333/66. Heading H2A. [Also in Division G1] A rotary or linear position transducer has relatively movable input and output windings each wound on an insulating non-magnetic former, the absence of a ferromagnetic core permitting high-frequency energization of the windings; and the input winding consists of three coils 42 on a former 40, Fig. 3, constituting a three-phase stator, for example, and the output winding consists of a coil 38 (or more coils) on a former 34 constituting a rotor. The stator coils are energized from a three-phase source (1, 2, 3, Fig. 1, not shown), the phase of the output of the rotor (4) being compared in a comparator (7) with one of the input phases to give a D.C. measure of displacement. The rotor output alternatively may be fed to an AND gate with one of the input phases, and also with a further higher frequency signal, the gate output being in the form of groups of pulses of the higher frequency, the number of pulses per group being proportional to the phase difference between the other two signals, and hence proportional to the relative displacement of rotor and stator. The output is taken from the rotor 38 by continuous leads if limited displacement only occurs or by slip-rings or inductive coupling. The transducer is contained in a dust core casing. In a follow-up arrangement (Fig. 2, not shown), two transducers (12, 16) are used, having their stators energized from a common three-phase source, the rotor outputs being phase compared in a comparator (19) the output of which controls a motor (21) driving one rotor (18) in response to movement of the other rotor (17) driven by a prime mover (13). A differential resolver may be included between the two transducers (12, 16) to measure relative movement, or the stators (14, 15) may be energized at different frequencies to produce differential rotation of one rotor relative to the other.
