Title: Apparatus for measuring the water content of oil
IPC: E21B47/10
Filed: 1974-05-13
Abstract: 1466768 Determining water content of oil  R M H CMELIK 13 May 1974 35705/74 Heading G1N In an apparatus for determining the water content of oil in pipes the variation in capacity of a probe through which the mixture flows and to which a high frequency signal is applied is monitored and the resultant signals transmitted along a cable connected to the probe at a lower frequency. In use the probe is lowered down an oil well on the end of the cable and comprises a housing containing the electrical equipment and which is extended at its lower end by a cylindrical outer electrode. A brass foil cylindrical electrode is mounted co-axially within the outer electrode and is protected by an insulating cover. Channels are provided in the outer electrode to allow the oil-water mixture to flow between the electrodes. A squarewave signal at a frequency greater than 100 KHz is applied to a voltage divider including a reference capacitor and the electrodes and the voltage developed across the electrodes is applied via a diode detector to a voltage to frequency converter. The latter includes a common collector transistor connected as a variable current drain for the emitter capacitance of a unijunction transistor connected as a low frequency relaxation oscillator. Thus the frequency of the oscillator varies in accordance with the capacity of the probe which depends upon the amount of water in the oil i.e., from 1 to 3 KHz. After amplification the signal is passed along the cable to the surface.

Title: Improvements in or relating to process to obtain plates for decorative overlays
IPC: E04F13/12
Filed: 1960-10-31
Abstract: 967,549. Ornamental metalwork; stamping. INTERPLAC S.L. Oct. 21, 1960 [Jan. 27, 1960; April 13, 1960; May 28, 1960; June 13, 1960 (2)], No. 36199/60. Headings B3A and B3Q. [Also in Division B6] In a method of embossing decorative overlays of sheet metal or other sheet materials simulating mosaic tiles &c. in which the sheet is grooved to form channels 6, Figs. 4, 8, separating polygonal embossed portions 5, the rows of embossed portions 5 are gradually brought closer together so that the base of each channel forms a solid rib 7 on the back of the sheet. In one example the sheet is formed by successive stages in which weakening slits 2, holes 4, or slots &c. are formed prior to embossing channels 6. The groups of embossing dies giving final form to the polygon portions 5 are disposed at distances apart which contract the sheet to close up the channel 6 and form the ribs 7. In another method the channels 102, Fig. 9, lying in one direction are formed progressively narrower by intermittently feeding the sheet 101 between embossing dies or rolls &c. The channels at right angles are then subsequently formed in the same progressive manner by feeding the sheet 101 transversely. In another method the longitudinal and transverse ribs 202, 205, Fig. 20, are progressively formed simultaneously between the same embossing dies or rolls so that the intermittently fed sheet emerges from a single pair of dies in its final form. In further modifications the polygonal sections of the sheet may be completely severed apart and are held together by a supporting sheet of flexible material on the front face and which may be subsequently removed after the application of the embossed portion.

Abstract: 1,046,498. Colour television tubes. M. SOGHOIAN. Sept. 18, 1963, No. 36712/63. Heading H1D. [Also in Division H4] An electric discharge tube 38 for use in conjunction with a black-and-white television C.R. tube 28 to produce a coloured image comprises an evacuated envelope 68 containing three superposed sections 44, 46 and 48, each comprised of a transparent photo-cathode (50, 52 54) and a transparent phosphorescent anode (56, 58, 60), the first section functioning, in response to illumination of its cathode, to produce red light, the second green light and the third blue light. The cathodes and anodes are brought out to connections 72 and the sections are brought into use in a desired sequence by the application of potentials between the cathodes and anodes. A small positive bias 74 is maintained on the cathodes continuously so as completely to suppress emission in a section not in use. Circuit arrangements are described (see Division H4) to permit frame sequential operation in response to frame sequential signals and signals in accordance with the American N.T.S.C. standards. In a modified construction, Fig. 3 (not shown), the assembly is incorporated as part of cathode-ray tube 28. Reference is made to the use of a screen 41 in tube 28 which emits infra-red or ultra-violet light, photocathodes 50, 52 and 54 being designed to be appropriately responsive. With such an arrangement a black-and-white image may be produced by operating the three sections of tube 38 simultaneously. Details are given of suitable methods for the formation of silver-caesium photocathodes and transparent phosphors, reference being made in connection with the latter, to an article " Some New Aspects of Germanate and Fluoride Phosphors " (Journal of the Optical Society of America, Vol. 37, No. 4, April 1947). A thin transparent conducting layer 57, 59, 61 e.g. of titanium dioxide, is deposited on the supporting panels or walls 66, 70, 64 prior to the application of the phosphor coatings.
