Title: Method of determining partial water saturation in shaly formations
IPC: G01V3/24
Filed: 1975-10-16
Abstract: 1519977 Borehole logging EXXON PRODUCTION RESEARCH CO 16 Oct 1975 [3 March 1975] 42450/75 Heading G1N The partial water saturation of a formation in a borehole is determined from the dielectric constant of the formation. Shallow and deep dielectric constant measure-   ments are made and the equation K/K O =S<SP>P</SP> w  is employed where K is the dielectric constant of a shaly sand formation, Ko is dielectric constant at 100% water saturation, Sw is water saturation and p is shaliness exponent. Sw is determined from the above equation and the partial hydrocarbon saturation SH obtained from the relation S H =1-Sw. The dielectric constant is obtained using a logging tool carrying a pair of bow shaped electrodes 7A, 7B, Figs. 1 and 2 (not shown) which is lowered down the borehole with the electrodes in contact with the formation. Squarewaves from generator 27 are applied to 7A and via low resistor 39 to 7B and the voltage appearing across resistor 39 is applied to the input of gated amplifier 29, the gating signal being derived from 37 and the output from 29 being fed to a surface oscillograph. The capacitance of the earth formation between the electrodes 7A, 7B is obtained from the area of the pulse on the oscillograph, the applied voltage from the generator, voltage across resistor 39 and the value of resistor 39. The dielectric constant is then calculated from the obtained capacitance value. Alternatively the instrument may be calibrated to measure dielectric constant directly in which case the dielectric constant of a number of samples corresponding to the drilled formation is obtained by known methods, the samples are placed successively in contact with the electrodes 7A, 7B and the area of the pulse on the oscillograph measured and a calibration curve plotted relating area and dielectric constant. The measurements on the borehole are then made and the results correlated with the curve.

Abstract: 1,043,352. Water Jet propulsion systems; air cushion vehicles. HOVERCRAFT DEVELOPMENT Ltd. Oct. 27, 1964 [Oct. 28, 1963], No. 42461/63. Headings B7K and B7V. A boat or air cushion vehicle has a water jet propulsion system comprising a flush intake 6 and an impeller 2 (Fig. 1, not shown) and an edge of the intake transverse to the direction of flow is formed as a movable surface, such as a rotating cylinder 10, or an endless belt (Fig. 2, not shown). The surface may be moved by the passage of water, or may be engine-driven, either by the engine 12 driving the impeller 2, or by a separate engine. The cylinder 10 is located on the forward edge of the intake, but a further cylinder 14 may be located at a rear edge to prevent separation when starting. For steering, a rudder 13 in the efflux may be used or the outlet 4 may be movable. The propulsion system may be fitted in a side wall of a sidewall air cushion vehicle (Fig. 3, not shown), and the movable surface may be formed by a pair of tyred wheels (Fig. 4, not shown), by which the vehicle can be propelled on land. In Fig. 4, the wheels 64 and impeller duct 59 are mounted on shock-absorbers 72, 73. The intake may be in a side of the sidewall, and the wheels and impeller may be driven separately. In another embodiment (Fig. 9, not shown), an air cushion vehicle has a flexible skirt 101 formed of separate segments each curved in horizontal section and described in Specification 1,043,351, a steerable and retractable wheel 105, and two tyred wheels 104 each in combination with a jet propulsion system.
Patent GB-424799-A (GB)
Abstract: 424,799. Photography. OPTICOLOR AKT.-GES., Glarus, Switzerland. Nov. 23, 1933, No. 32791. Convention date, Nov. 24, 1932. [Class 98 (ii)] Black and white films suitable for ordinary projection are obtained from colour-record or stereoscopic lenticular films, by contact or projection copying on to smooth films in such a manner that the partial pictures of the lenticular original are integrated over the width of a lenticular element. Thus, the emulsion side of the smooth film may be placed in contact with the embossed side of the lenticular film ; or the films may be arranged with the emulsion surfaces facing each other and spaced apart by a celluloid strip &c. The films may be copied with the emulsion surfaces in contact with slight relative movement laterally of the lenticular elements; or the films may be caused to move at a slight angle and copied through a slot-shaped light window. For projection copying, the spreading of the image is effected by a slight want of focus or by the use of a cylindrical lens. As a further modification, a copy film of weak recording power may be employed. Preferably a smooth negative film is made and exhibition copies made therefrom. The Specification as open to inspection under Sect. 91 states that copying may also be effected with a matte or opal disc adjacent to the image layer of the original film; and describes also the application of similar methods for copying lenticular films on to smooth multicolour screen films. This subject-matter does not appear in the Specification as accepted.

Abstract: 1409117 Utilizing photo-detectors RANK ORGANIZATION Ltd 19 Sept 1973 [19 Sept 1972] 43278/72 Heading G1A The position of the optical axis of a lens 12 on a rotatable carrier 11 is determined by reflecting light from a lamp 14 on to photo-detectors P<SP>1</SP> The light passes via lenses L 1 , L 2  and L3 to the lens under test; it is reflected back via L 3  to beam splitter B 5 , and thence to the photo-detectors. Apertures S 1 , S 2  and S 3 , with central stop S 4 , ensure that only the light from a small area of the lens reaches the detectors. The output of the detectors, which is A.C. due to chopper 15, is amplified at 16 to give a display on oscilloscope 19 which shows the inclination of the lens' optical axis to the axis of the beam of light incident on the lens as the carrier is rotated. The detectors comprise plural light sensitive regions, and the sum of their outputs is kept constant by an AGC device 17 so that the apparatus has a constant sensitivity regardless of the reflectivity of the lens under test. This AGC will be automatically overridden if the oscilloscope display is about to go off the screen however. An output not subject to AGC drives meter 20 to aid focusing during setting up; a compensating plate C 1  allows the light to be centred on the axis of carrier 11 before testing starts.

By this method a very hard wearing surface, which has a chilled structure and contains a large proportion of cementite, is formed. This portion may have a hardness of up to 900 Vickers Hardness while the hardness of the lower part which may be at least one third of the height of the seal remains unaffected, i.e. about 370 Vickers Harness. An electron beam 3 is used to melt the surface, the beam being oscillated as the blank travels beneath it so that it follows a trace 4. Alternatively a laser beam, plasma, arc or other heating means may be used. The blank may be heat treated for stress relief prior to the final working operation, which comprises final finish cutting or grinding. The cast iron may be acicular cast iron.
