  • Publication number: 20230246534
    Abstract: A canned rotodynamiic flow machine (1) configured for operating with a working fluid such as molten salt of a molten salt nuclear reactor, comprising an impeller (6) arranged in a volute (3), with an inlet (4) and an outlet (5) for the working fluid, an induction or reluctance motor or generator comprising a stator (10) and a rotor (8), a can (18) separating a working fluid area in which the rotor (8) is arranged from a dry area containing the stator (10). The rotor (8) is operably coupled to the impeller (6). The stator (10) comprises stator windings for inducing a magnetic field that penetrates the rotor (8). The stator windings are distributed in slots (11) arranged in the stator (10). The part of the stator windings inside the slots is formed by one or more electrically conductive solid bars (12). An active magnetic bearing for use in a canned rotor dynamic flow machine for a molten salt nuclear reactor, comprising a stator (110,210) and a rotor (108,208).

  • Publication number: 20210252212
    Abstract: An osmotic actuator (110) for an injection device (100) is disclosed, which osmotic actuator (110) comprises a pressure chamber (180; 280; 380) having one or more outlets (182; 282; 295; 395) and containing a draw solution, one or more osmotic membranes (130), a cavity (140) containing water, and a dilution-compensating arrangement, wherein the one or more osmotic membranes (130) forms a part of an internal surface area of the pressure chamber (180; 280; 380), wherein the cavity (140) containing water abuts at least part of an external surface of the one or more osmotic membranes (130), and wherein the dilution-compensating arrangement is arranged to compensate for the dilution of the draw solution near the one or more osmotic membranes (130), which occurs when water from the cavity (140) enters the pressure chamber (180; 280; 380) through the one or more osmotic membranes (130). Furthermore, an injection device (100) comprising such an osmotic actuator (110) is disclosed.

  • Publication number: 20120270122
    Abstract: The present invention relates to a method of operating a fuel cell system comprising one or more fuel cells with a proton exchange membrane, wherein the membrane is composed of a polymeric material comprising acid-doped polybenzimidazole (PBI). The method comprises adjusting the operating temperature of the fuel cell to between 120 and 250° C., supplying an oxidant stream to the cathode, and supplying a humidified fuel stream to the anode, said fuel stream comprising dimethyl ether, wherein dimethyl ether is directly oxidised at the anode.

  • Patent number: 6346186
    Abstract: A method for electrochemical phosphating of metal surfaces, particularly stainless steel, in connection with cold forming of metal workpieces, which method provides the cold formed workpiece with a lubricant after phosphating, involves an electrochemical phosphating through a cathodic process applying an aqueous phosphating solution containing 0.5 to 100 g Ca2+/l 0.5 to 100 g Zn2+/l 5 to 100 g PO43−/l 0 to 100 g NO3−/l 0 to 100 g ClO3−/l and 0 to 50 g F− or Cl−/l by which the temperature of the solution is between 0 and 95° C., the pH-value of the solution is between 0.5 and 5, and the current density is between 0.1 and 250 mA/cm2. This gives a good lubrication effect, a good adhesion to the metal surface, particularly stainless steel, and a more expedient texture than ordinary phosphating.
