Abstract: A gas heating process is disclosed in which a gas to be heated and carbonic gas causing an exothermic reaction with soda-lime are caused to pass simultaneously over a charge of soda-lime. The device of the invention includes a cartridge with a first chamber containing the charge of soda-lime and a second chamber containing the amount of carbonic gas required for starting the exothermic reaction, and a means for placing the two chambers in communication. The first chamber is connected to an inlet for the mixture of gas to be heated and carbonic gas for maintaining the reaction, and also is connected to an outlet (3) for the heated gas.

Abstract: Fluid distribution connector made up of a connector body (1) provided with a fluid intake (4, 33') and means to assure the circulation of the fluid between this intake and a connector tip (13, 39) only when this tip is introduced into the connector body, characterized in that it comprises a jacket (2, 25) whose rear chamber (3, 26) can communicate with fluid intake (3, 34) and in which slides a piston (5, 17) provided with a circulation duct in the form of an axial blind hole (6, 18) open at the front and radial bores (7, 19) at the rear, this piston being kept by the pressure of fluid in the closed position, for which the radial bores are located in the jacket, against a stop (8, 36), while introduction of connector tip (13, 39) shove it in its open position for which radial bores (7, 19) come out in rear chamber (3,26).
