Abstract: BUTADIENE POLYMERISATION PROCESS            ABSTRACT OF THE DISCLOSURE          Catalytic polymerisation of butadiene to cis-1,4-polybutadiene, conducted in the absence or substantial absence of solvents or diluents. .    According to said process, a catalytic mixture is prepared by bringing into contact, in a hydrocarbon vehicle, one or more neodymium compounds, one or more halogen contributor compounds, one or more compounds containing hydroxyls, and an aluminium organometal and/or hydride compound. Said catalytic mixture is brought into contact with liquid butadiene monomer, and the resultant mixture is fed continuously to one end of an elongated plug-flow polymerisation reactor in which the butadiene is polymerised. Alternatively, said polymerisation reactor is fed continuously with a stream of the catalytic mixture and a stream of liquid butadiene. The heat of polymerisation is removed by partial evaporation of the butadiene monomer, so that by controlling the pressure of this latter it is possible to maintain the polymerisation temperature within the predetermined range.  By also controlling the catalyst composition, the butadiene monomer/catalyst ratio, the polymerisation temperature and the residence time in the reactor, it is possible to produce mixtures containing from about 25% to about 70% of polymer by weight, which are discharged continuously from the other end of the polymeri-sation reactor. The cis-1,4-polybutadiene is recovered as final product from the discharged mixture by evaporating the unreacted butadiene and any solvent used as the catalyst vehicle from the polymer mass, to which a short stopper for the catalyst and stabilisers against thermo-oxidative degradation have been added. This evaporation takes place in an extruder-desolventiser.

Abstract: PATENT APPLICATION              ETUDES ET FABRICATIONS FLOPETROL       METHOD AND APPARATUS FOR OIL WELL MEASUREMENTS        In a drill string or production tubing is inserted a body member (100). This body member has a flapper valve (121) actuated by a jacket (130) itself controlled by a control unit (200) lowered at the end of a cable (199). The control unit has an internal rod (251) with a pressure gage (252) at the head as well as an external tube (201) in which the rod (251) slides.   The tube (201) is anchored on the body member (100) and the rod (251) on the jacket (130). A large passage (140) goes around the two anchoring points. A small tubular passage (150) makes it possible to link the upstream part of the flapper valve (121) to the rod (251) and, from there, to the pressure gage.        Figure 1.

Abstract: ABSTRACT OF THE DISCLOSURE      A multiple gob glass shearing mechanism in which the sets of opposed shear blades are supported for movement toward and away from each other in a straight line or with parallel motion.  One set of shears is mounted on a shear guide that can be adjusted up or down relative to the holder of the opposed set of shears.  This adjustment is for the purpose of adjusting the tension on all the sets of blades simultaneously and can be affected when the shears are in operation.  The drive for the shears may be unlatched for safety purposes when out of position and when put back into operation the shear blades will not close unless the latch is refastened.
