  • Patent number: 10989580
    Abstract: Apparatus for feeding doses of fluidisable materials comprising one upper Intel pipe (1?, 1?), one lower outlet pipe (2?, 2?) and a Pausing (6?,6?). and a fluidising element (5?,5?) for controlling outflow of materials through the outlet pipe (2?, 2?), The apparatus further comprising a control volume constituted by a chamber (3?,3?) between the Intel pipe (1?, 8?) and the outlet pipe (2?,2?) and a fluidising element (4?, 4?) for controlling inflow of materials Into the chamber (3?, 3?). A diverter (7?,7?) la arranged between the Inlet pipe (1?, 8?) and the outlet pipe {2?, 2?) defining said chamber (3?, 3?) between said Inlet pipe (1?,8?) diverter (7?,7?) the housing (6?, 6?) and the fluidising element (5?,5?). The Invention also relates to a method for feeding doses of fluidisable materials by the apparatus.

  • Publication number: 20180023206
    Abstract: An anode for use in an electrolysis process for production of aluminium in cells of Hail-Héroult type, the anode comprises a body or block (120; 20) of calcinated carbonaceous material connected with an electrical current lead, where said current lead being connected with an anode rod (103; 3) and further being part of an anode hanger (101; 1). The current lead comprises at least one metallic suspension plate(s) (104; 4. 4?) with vertically oriented redding plates (105 105??,5, 5?) at least partly embedded by their lower partly in corresponding recesses (113, 113??, 13. 13?; 100, 100?) in the top of the carbonaceous block (120; 20} and further connected by mechanical fixation means (108; 8; 14, 16). Said recesses are wider than the rodding plates and being filled with an electric conductive particulate material only. It Is also described a method for processing an undercut recess (10) in the an ode top for mechanically fixing the anode block (20) to a protrusion (8) on the current lead.

  • Patent number: 6994210
    Abstract: A conveyor belt (2) includes a reinforcement (4) built up of at least one reinforcement layer (4a, . . . ) which includes fabric or cord and cover plates (8a, 8b) can be arranged on the carrier side and/or running side with the cover plates being made of elastomer or a rubber mixture. In order to prevent baking-on and dirtying during transport of the different goods, especially mass goods, the conveyor belt (2) is provided with a practice-proven durable and permanent anti-adhering surface. A plastic coating (10) is applied to the conveyor belt (2) on the carrier side and is an anti-adhering coating. The plastic coating (10) preferably is made of ultra high molecular polyethylene. The polyethylene foil (10) can be vulcanized to the carrier side cover plate (8a) or, in lieu of the carrier side cover plate (8a), the polyethylene foil can be vulcanized directly to the reinforcement (4) comprising at least one rubberized reinforcement layer (4a, . . . ).

  • Patent number: 6419925
    Abstract: The present invention relates to the identification of toxoplasma gondii antigens and the preparation thereof by genetic engineering. A cDNA expression gene bank of this parasite was prepared. Recombinant clones which are of diagnostic interest were identified using a high-titer rabbit anti-Toxoplasma gondii serum, and isolated.
