Abstract: This device comprises a cable working line bearing a lower assembly and a winch for maneuvering the line. The hydraulic central unit (46) of the winch includes a tank (50) for storing a hydraulic control fluid, a pump (52) for driving the hydraulic fluid, connected to the tank (50) through an upstream conduit (54) and at least one hydraulic motor (56) for driving the drum (42) connected to the pump (52) through an intermediate conduit and connected to the tank (50) through a downstream conduit. The hydraulic central unit comprises a regulator (62) for the hydraulic fluid flow rate at the outlet of the pump (52). The regulator (62) is driven according to at least one hydraulic fluid pressure depending on the load exerted on the motor (56) by the rotary drum (42), said or each pressure being directly taken on one of said conduits.

Abstract: The device comprises a tubular casing (2) having a first coupling element (5) for feeding it with a first fluid at a first axial end, and a second coupling element (6) for exhausting a mixture of the first fluid and a second fluid at a second axial end. An internal fluid guide duct (18a, 18b) is placed coaxially inside the casing (2) of the mixer. The device further includes a third coupling element (7) in a lateral position passing through the casing (2) between the first coupling element (5) and the second coupling element (6) and opening out into a cylindrical chamber (3) of the mixer in a position facing the outer surface of the guide duct (18a, 18b). The guide duct (18a, 18b) may be made up of two portions and comprises a wall having an insulating space (19a, 19b) formed therein, which space is put into communication with the cylindrical chamber (3). The device of the invention can be used in particular for cooling supercritical water used in a process of oxidizing effluent in supercritical water.

Abstract: A Modular assembly or islet for pneumatic distribution which comprises a number of modules or blocks each consisting of a slice and each incorporating pneumatic connectors and electrical connectors. Two pneumatic distributors are mounted at 90° to one another on two adjacent sides of the block or module so that the pneumatic connectors and the electrical connectors are common to the two distributors. The blocks or modules, with their respective pairs of distributors, are removably mounted on the connectors so as to assemble them side by side, thus constituting the modular assembly or islet for distribution with the desired number of pneumatic distributors.

Abstract: A small electrically operated valve in which a control solenoid sub-assembly is mechanically associated in a non-dismantleable fashion by means of a face with the corresponding face of a pneumatic switching sub-assembly having a valve member. Each of the two sub-assemblies is of plastics material and comprises passage portions which may be brought into aligned relationship to form at least one aligned passage capable of receiving at least one small cylindrical metal pin, a first end thereof being positioned below the surface at which the entry of the aligned passage opens, while the other end is in the vicinity of a metal protective portion which is positioned inaccessibly in either one of the two sub-assemblies and which is disposed substantially transversely to the axis of said aligned passage.

Abstract: A small low power electromagnetic valve is provided using valving means for providing pneumatic switching. Two orifices connected respectively to the pressure and to the discharge side are alternately closed by a first valving means carried by the plunger core of an electromagnet and respectively by a second valving means associated with a weak spring; a lever receives one end of the plunger core and the active face of said second valving means at pivoting distances, 1 and L, such that ##EQU1## where .phi..sub.1 and .phi..sub.2 are diameters of the orifices.

Abstract: The invention relates to a pneumatic indicator comprising a member or body and a transparent window behind which a spherical pivoting moving body can assume two distinct positions visible from the outside when the end of a lever placed in the member transmits to a cavity of the moving body, either the movements of a membrane or of a piston under pressure action or the movements resulting from a restoring spring.Such indicators are particularly used in equipment for monitoring the operation of an installation controlled by automatic pneumatic equipment or in industrial atmospheres where incandescent lamps cannot be used because of the explosion hazard.
