Abstract: ABSTRACT OF DISCLOSURE     Disclosed is a method of preparing an inflatable packer including a mandrel and a sleeve for insertion into a fluid filled well bore.  The method includes pressure testing the sleeve and its connection with the mandrel with a gas without introducing any incompressible fluid between the area of contact be-tween the sleeve and mandrel.  The method also includes the filling any pressure vulnerable areas in the packer not in the area of contact of the sleeve and mandrel with an incompressible fluid.

Abstract: CENTRIFUGAL SEPARATOR AND METHOD         OF OPERATING SAME                 ABSTRACT OF THE DISCLOSURE          A continuous flow device for separation of par-ticles of differing densities in a centrifugal force field. Very small particles of differing densities that are normally very difficult or impossible to separate in the usual commercial gravity separation devices can be separated because of the increased settling force due to the centrifugal force field and also the buoyant force on the particles of lesser density caused by a thickened slurry layer.  A thin film of a slurry of solid particles of differing size and density travels over a revolving surface of such configuration that the slurry flows in a substantially laminar manner.  As the thin film of slurry flows along the surface, the particles of greater density tend to concentrate in the region next to the surface. While the particles of lesser density remain in or are forced into the fraction of the film closest to the axis of revolution.  Before the film of slurry reaches the end of the flow path it is passed over a splitting device to separate the fraction of the film containing particles of greater density from the fraction containing particles of lesser density.

Abstract: ABSTRACT OF THE DISCLOSURE    A carbon brush assembly comprises  a brush box having a slit along one side thereof, and a carbon brush slidably mounted in the brush box with a spring connected between the brush box and the brush to re-siliently urge the brush outwardly.  An electrically conductive pin is inserted in a transverse bore in the brush and extends through the slit for movement there-along.  A brush lead is electrically connected to the pin and a stop associated with the slit adjacent the outer end thereof.  The stop forms a closed end of the slit for limiting movement of the pin therealong under the influence of the spring, and so retaining the pin in the slot when said brush wears out.  Preferably, the brush is formed with breaking incisions in its sides adjacent the pin to enable the protruding end of the brush to break off and interrupt electrical connection with a commutator when the brush has worn to the end of its useful life.

Abstract: Technique particulière de prospection géophysique, dite " à courants transitoires ". Un dipôle récepteur capte répétitivement la réponse du sous-sol à une excitation impulsionnelle au niveau du dipôle émetteur. Les passages ainsi captés répétitivement sont composés statistiquement en une représentation brute de la réponse transitoire, qu'un prétraitement transforme en représentation lisée et normalisée. Pour chaque station, on prend avantageusement la dérivée logarithmique de cette réponse, (indicatrice locale IL). A partir de celle-ci, on détermine une indicatrice régionale IR, puis par différence (IL-IR) des indicatrices résiduelles. Convenablement représentées, celles-ci font apparaître certains traits de la structure du sous-sol.
