In a process for the separation of nitrogen from air, gaseous air is compressed in compressor 2, cooled and purified in a reversing heat exchanger 12, and then distilled in a single distillation column 32 to obtain a pure gaseous nitrogen overhead stream 34 and an oxygen enriched liquid bottoms stream 36. All of the bottoms stream 36 and a portion of the overhead stream 34 are passed to a condense...

Biaxially stretched composite film comprises a 5-50 mu thick polyester base coated with a layer of PVA, having a polymerisation degree (DP) of more than 350, of thickness of most 0.3 mu . The base has an average rugosity (roughness) (RZ) of at most 0.3 mu on the faces coated with PVA, these faces having no more than 20 pics of high at least 1 mu and no more than 150 pics of height 0.4-1 mu . Th...

Polluted aqueous effluents can be treated in a centripetal flotation separator. Liquid for treatment (FC) is directed into a rotating flux (FT1), in a zone of the separator which acts as a cyclone (20). Heavy particles are separated. The rotating liquid stream passes through (FT2) a flotation tube (6) where gas bubbles are injected into the periphery of the stream to form a mousse which collects f...

A device for discontinuing and automatically restoring the operational function of a spring brake actuator comprises a piston (9) with a piston rod (10) and a spring (13) actuating the piston and piston rod in a working direction for brake application at falling brake fluid pressure on the piston, a slitted, resilient locking ring (15) being arranged in grooves (16, 17) facing each other in the pi...

A method of improving the paint adhesion properties of a cycloolefin polymer article comprising exposing the surface of said article to a solution of sodium hypochlorite or a solution of potassium permanganate. Preferably the solution is of sodium hypochlorite and it further contains a detergent solution.

The present invention relates to a method and device for logging in a non-eruptive oil-production well. The method is characterised in that the well is activated to make it produce effluents, on either side of first measurement means 10 and in that the said measurement means 10 are used to treat at least part of the effluents coming from upstream 18 of the flow, relative to the said measurement me...

Two concentric fluid pistons (7,8) act on the support (10) for the piece (1), the first piston (7) having a large travel. The second piston (8), with a reduced travel, is inserted between the support and the first piston. A fixed part (18) mating with a gear tooth prevents angular movement of the piece. The two pistons are supplied with fluid to advance them and restrain the piece by the support a...
