Abstract: 864,509. Electrical measuring - devices. METTLER, E., [trading as METTLER, FABRIK FUR ANALYSENWAAGEN, E.]. July 13, 1959 [April 4, 1959], No. 23980/59. Class 40 (1). In a precision balance the magnetic coupling between a pair of coils is varied by inserting a conducting screen into the magnetic circuit in order to indicate the deflections of the balance beam. Each coil is wound on a U-shaped yoke, 4 and 5, Fig. 1, of powdered ferromagnetic material stuck to a conducting base-plate 3 by a synthetic resin. Conducting non-magnetic screen 11 attached to the balance beam moves freely between pole-pieces 4<SP>11</SP> and 5<SP>11</SP>, the magnetic field being confined to the gap between these pole-pieces by screens 13 and 14 and cover 20. The coupling between the coils may be measured by connecting one coil to an oscillator and the other to a valve voltmeter via coaxial cables 9 and 10, or alternatively the coils may be connected, either in series opposition or series aiding, in the frequency determining circuit of an oscillator so that the frequency of the oscillator is a measure of the position of lug 11.

Filed: 1957-07-30
Abstract: 844,174. Electric tests. JERSEY PRODUCTION RESEARCH CO. July 30,1957 [Aug. 22, 1956], No. 24062/57. Class 37. Apparatus for energizing a well bore penetrating subsurface earth formations for the presence of hydrocarbons comprises, in a single unit, means for contacting said earth formations with a solution containing a surface active agent which causes preferential wetting of the earth formations by any hydrocarbons present therein, and means for detecting the electrical resistivity of the earth formations both before and after the preferential wetting. The apparatus shown comprises a device 40 having at its upper end extensible arms 41 carrying ploughs 42 below which is mounted a resistivity measuring device consisting of centralizers 43 and electrodes 44 connected to leads 45 which pass through a cable 21 to surface recording equipment. Further extensible arms 46 carrying ploughs 47 are provided with passages 48 connected through flexible conduits 49 and a conduit 50 to a deformable or resilient reservoir 51 for a solution containing a surface active agent. The conduit 50 is provided with solenoid valves 52 and 52a operable from the well head by way of leads 53 and 54. A second resistivity measuring device consisting of centralizers 55 and electrodes 56 is mounted at the lower end of the device 40 and connected to the surface recording equipment by leads 57. In use, the device 40 is lowered down the well on the cable 21 with the arms 41 and 46 retracted. The arms are then released under the action of springs and the device gradually raised. The ploughs 42 disrupt the filter cable 18, allowing the electrodes 44 to bear against the earth formations to obtain a resistivity log. The ploughs 47 disrupt any reformed filter cake and contact the formations with solution from the reservoir 51 thus causing preferential wetting of the formations by any hydrocarbons present. A resistivity log of the contacted formations is obtained by means of the electrodes 56. A comparison of the two logs, which may be recorded simultaneously or separately, indicates the presence of hydrocarbons. In a simplified device (Figs. 1 and 2, not shown) the arms 41, centralizers 43 and electrodes 44 are omitted and the electrodes 56 used to obtain two logs of the formations, one before and one after releasing the solution by means of the valves 52 and 52 a.

Title: Method of and material for dry cleaning
IPC: D06L1/04
Filed: 1931-09-14
Abstract: Fabrics are cleaned by treating with an organic dry-cleaning solvent in which water is dispersed with the aid of a mahogany sulphonate. Preferably the mahogany sulphonates used are obtained by treating petroleum with fuming sulphuric acid or sulphur trioxide and extracting the sulphonated oil layer with alcohol.  The extracted mahogany sulphonates are then incorporated in water and dissolved in a solvent such as naphtha, carbon tetrachloride or Stoddard solvent, to form a solution which is optically clear.  Small amounts of alcohols or cresol may be added as dispersion assistants.  Fabrics may first be extracted with a solvent to remove most of the grease, and are then immersed in the solution by which water-soluble stains such as syrup are removed.  The used solvent is agitated with a dilute solution of common salt to replace the water removed by the fabric.  Reference has been directed by the Comptroller to Specification 19759/12, [Class 91, Oils &c.].
