Abstract: Abstract of the Disclosure A homogenisation method particularly applicable to fuel oil containing water and/or coal dust is described. Ideal homogeneity is achieved by supplying the substances to be homogenised between cooperating surfaces one of which is afforded by the internal circumferential surface of a homogenisation chamber and the other of which is af-forded by the external circumferential surface of the first of a coaxial stack of discs whose edges are cylindri-cal or are part-spherical, causing the substances to cross the path of rolling of the discs so as to cause disintegra-tion of a phase or phases insoluble in the liquid or one said liquid between the discs and said circumferential sur-face in the region of the point of the rolling engagement as the substances pass under gravity down through the homogenisation chamber and withdrawing the homogeneous liquid obtained from the other end of the chamber beyond the path of rolling movement of the discs, the discs being unrestrained mechanically against movement towards and away from the internal surface of the chamber throughout their rolling motion and the pressure between them and the chamber surface being produced solely by centrifugal force.   1.

Abstract: ABSTRACT OF THE DISCLOSURE     A capacitor comprising at least two electrodes separated from one another by an elastic dielectric formed of rubber and/or plastic for measuring forces acting upon one of the ¦ electrodes -- the so-called measuring electrode -- by detecting the resultant change in capacitance.  The dielectric in its un-loaded state is pre-compressed and preferably possesses a number of hollow spaces.     A method is also disclosed for measuring forces randomly occurring as a function of time as well as locally within n predetermined surface  wherein the forces arc applied to a measuring electrode of a capacitor containing an elastomeric dielectric.  The measuring electrode corresponds to the pre-determined surface.  There is then recorded the change in capacitance of the capacitor and which capacitance change corresponds to the course as a function of time of the action of the force.

Abstract: SINGLE WELL TRACER METHOD TO EVALUATE ENHANCED RECOVERY         Abstract Data useful to evaluate the effectiveness of or to design an enhanced recovery process (the recovery process involving mobilizing and moving hydrocarbons through a hydrocarbon-bearing subterranean formation from an injection well to a production well by injecting a mobilizing fluid into the injection well) are obtained by a process which comprises sequentially:  determining hydrocarbon saturation in the formation in a volume in the formation near a well bore penetrating the formation, injecting sufficient of the mobilizing fluid to mobilize and move hydrocarbons from a volume in the formation near the well bore penetrating the formation, and determining by the single well tracer method a hydrocarbon saturation profile in a volume from which hydrocarbons are moved.  The single well tracer method employed is disclosed by U.S. 3,623,842.  The process is useful to evaluate surfactant floods, water floods, polymer floods, CO2 floods, caustic floods, micellar floods, and the like in the reservoir in much less time at greatly reduced costs, compared to conventional multi-well pilot test.

Abstract: IMPROVED GAS PANEL SPACER                 ABSTRACT OF THE DISCLOSURE    Gaseous discharge display systems represent a sophisticated technology which requires that the physical parameters of the de-vice such as the discharge gap be maintained within close tolerances.

Also disclosed are means for modifying the physical characteristics of the spacers to eliminate reflected light and render the spacers substantially invisible.

Abstract: ABSTRACT OF THE INVENTION           A Doppler radar having a single sense Doppler signal from the rf mixer.  A single sideband modulator in a common antenna system for transmitting and receiving shifts the fore and aft beams to achieve a single sense Doppler signal.  The use of the single sideband modulator results in a differential Doppler shift between fore and aft beams of only a few hundred knots, thereby permitting use of low cost components.  A sin-gle sense Doppler also reduces the Doppler passband by a 2:1 factor which permits the power supply frequency to operate at a higher frequency than the receiver.

Abstract: REPOSITION FEATURE FOR AN ELECTRONIC TYPEWRITER                   Abstract On electronic typewriters which have the ability to record into a small working memory the escapement of the characters which are keyed at the keyboard, it is many times advantageous to be able to reposition the carrier at the rightmost end of the typed material automatically. This is particularly advantageous when it has been necessary to back the carrier up along the printed line for purposes of erasing, correcting or inserting material into that line.  Disclosed herein is an electronic typewriter which is controlled by the electronic logic such that the depression of a selected control key will result in the carrier moving from a position within the typed text on a particular line to the right most position the carrier has occupied within that line during earlier typing.       This is accomplished by temporarily storing the rightmost carrier position as recorded in the escapement register into a working memory and then upon the appropriate command from the keyboard, using that location in the manner that a tab stop location would be used and creating a tab like command movement to cause the carrier to go directly to that point and stop.

Abstract: Apparatus for Removing a Welding Bulge from Resistance Welded Pipes Abstract A welding bulge removing apparatus comprises a U-shaped carrier adapted to be placed by means of rollers on the welded pipes at the weld zone. Mounted on the carrier are cutting tool holders movable to and from the weld bulge.          The invention resides in that the welding bulge removing apparatus is provided with a motor-operated carriage having support rollers and a driving gear wheel and the carrier has an arcuate guideway and a toothed segment both mounted thereon and in engagement with the support rollers and the gear wheel respectively. Moreover, the carriage is adapted to be rigidly connected to a lifting mechanism of a vehicle used for raising and carrying the welding bulge removing ap-paratus, whereby in operation rotation of the carrier is effected, while the carriage remains immobilized.   Such welding bulge removing apparatus permits a higher performance in removing a welding bulge from resistance welded pipes under field conditions while laying pipelines for the long-distance transportation of petroleum and gas.
