  • GAS MIXING PUMP WITH VARIABLE INJECTION SECTION
    Publication number: 20100170574
    Abstract: The invention relates to a pump including: a gas mixing housing (1); ducts (2, 3) for supplying the housing (1) with HP and IP gases and giving into the mixing housing (1); an outlet duct (3) for the mixed gases; a pneumatic actuator (10) provided in the HP-gas supply duct (2) including a mobile piston connected to a stopper (12) whose position in the duct (2) determines a passage section of the HP gas towards the mixing housing (1); a control chamber (13) of the mobile piston adapted to be fed under pressure for determining the position of the mobile piston; a pneumatic circuit provided between a pressure source and the control chamber (13); characterised in that the pneumatic circuit includes at least one leak valve (22) adapted for generating a leak in the pneumatic circuit for modifying the pressure supplied to the control chamber (13).

  • Recombinant production of proteins using 7B2 protein
    Patent number: 5804417
    Abstract: The invention lies in the field of genetic engineering and, in particular, is concerned with the use of 7B2 as chaperone in vivo or in vitro. The invention accordingly concerns a method for producing a desired protein in vivo with the aid of recombinant cells capable of expressing 7B2 and of expressing and secreting said desired protein. Another aspect is accordingly an in vitro method for the deaggregation or prevention of aggregation of protein by treating the protein with 7B2.
