Abstract: METHOD AND APPARATUS FOR ACQUIRING      SEISMIC SIGNALS IN A BOREHOLE          Invention of Jean-Luc Decorps and Guy Blanpain Abstract of the Disclosure The present invention relates to the acquisition of seismic signals at different levels in a borehole, in response to the generation of seismic waves by a source placed on the surface or in the vicinity of the surface. The acquisition is carried out by means of a sonde suspended in the borehole from a cable and equipped with an anchoring pad. At each acquisition level, the pad is anchored in the borehole wall to couple the sonde to the formation, and then the pad is released from the wall once the acquisition is over. The signals acquired are then sent to the surface by means of the cable. The force with which the pad is anchored in the wall is controlled by means of a feedback arrangement which includes a sensor arranged in the pad itself. During the sonde movements from one level to another, the pad is kept in contact with the wall.

Abstract: Abrasive Surface Coating Process for Superalloys Abstract A combination of sintering, plasma arc spraying, hot isostatic pressing and chemical milling is used to form an abrasive surface on an article.  Alumina coated silicon carbide particulates are clad with nickel and sinter bonded to the surface of a super-alloy turbine blade tip.  An impermeable layer of plasma arc sprayed superalloy matrix is deposited over the particulates and then has its inherent voids eliminated by hot isostatic pressing.  The abrasive material so formed on the surface is then machined to expose the particulates.  Next, a portion of the matrix is removed so that the machined particulates project into space and are thus best enabled to interact with abradable ceramic air seals in a gas turbine engine.  The ceramic par-ticulates are sized so they are larger than the finished thickness of the abrasive and they have small aspect ratios.  Thus, a high density spacing can be achieved while at the same time it is insured that matrix adequately surrounds the particles and holds them in place during use.

Abstract: ABSTRACT     "Improvements in and relating to breathing apparatus"     A self-rescue breathing apparatus has a radial-flow purifier 3 connected between a mouthpiece and a breathing bag 10.  An outer plenum of the purifier is open at both ends, a central conduit is open only at the breathing-bag end.  Flap valves 50A and 50B control the flow of gas so that exhaled breath passes radially inwards through the purifying medium which gas for inhalation passes freely up the outer plenum, reducing both the resistance to flow and the heating of the inhaled gas that the purifier (which works by exothermic chemical reaction) would otherwise cause.
