Abstract: A device designed for being adapted to surround a duct formed with one or several orifices operable for feeding a fluid to an apparatus, such as a reactor, used for the treatment of liquids, notably water, and including a resiliently deformable membrane, also formed with one or several orifices communicating with that or those of the fluid feeding duct, characterized in that it is made of two half shells threaded and clamped onto the fluid inlet duct, one of which having a housing for the resiliently deformable membrane and an orifice for the distribution of the fluid to the apparatus.

Abstract: The parent patent deals with the continuous extn. of sludge from the surface of a rectangular flotation tank by means of a moving bridge with a horizontal drum fitted with suitable blades. In addition the sludge is simultaneously extracted from points at the bottom of the tank by means of a suction arm. The bridge moves on four wheels. A drum consists of an axle carrying two circular end-plates which have necks which support the assembly and rest on pulleys mounted on the bridge. The drum is fitted with blades and acts on the sludge at the surface. The bridge includes two suction arms, the object of the addition, which consists of tubes in the form of an inverted "T" with the horizontal portion, at the base of the tank. The sludge can be drawn up through holes by pumps and pumped along pipe to the receiving device for the surface sludge. The sludge can be pumped while the bridge is moving in both directions; the surface and the base sludges can be extracted simultaneously so that the efficiency of the appts. described in the parent patent is thus improved.

Abstract: This invention provides a method and an apparatus for effecting counter-current mass exchange between two non-miscible phases A and B, for example a liquid phase A and a liquid or solid phase B, circulating in opposite directions from one end to an opposite end of a vertical tower comprising a plurality of superposed chambers in which the first phase A is caused to circulate continuously and the second phase B is caused to circulate discontinuously. One chamber is empty and is adapted to receive the phase B contained in the next chamber thereabove, the two chambers being isolated from any supply of phases A and B. A small fraction of the liquid phase A is diverted for directing continuously this phase to the other chambers of the tower, the thus diverted fraction being introduced into the next chamber above the empty chamber for carrying away the phase B contained in the lower empty chamber, this diverted fraction being reintroduced into the circuit.

Abstract: Dispositif destiné à être adapté autour d'une tuyauterie munie d'un ou de plusieurs orifices servant à l'amenée d'un fluide à un appareil, tel qu'un réacteur, utilisé en traitement de liquides, notamment d'eau, et comportant une membrane élastiquement déformable, également munie d'un ou de plusieurs orifices communiquant avec celui ou ceux de la tuyauterie d'amenée de fluide, caractérisé en ce qu'il est constitué par deux demi-coquilles (1, 1a) enfilées et serrées sur la tuyauterie 2 d'amenée du fluide, et dont l'une présente un logement pour la membrane élastiquement déformable (3) et un orifice (4) pour la distribution du fluide à l'appareil.
