    Abstract: A system for producing a syngas from a biomass material. The system compacts a loose biomass material to form a compacted biomass material at an entrance of a reactor tube, and then heats the compacted biomass material within the tube to form ash and a fuel gas mixture. The fuel gas mixture is withdrawn from the tube and the ash is removed from the tube through an exit thereof. Ingress of air into the tube is inhibited by forming a plug of the biomass material at the entrance of the tube and a plug of ash at the exit of the tube. A neutral atmospheric pressure is maintained in the reactor tube relative to pressure outside the reactor tube by monitoring and adjusting a volumetric rate of the fuel gas mixture withdrawn from the reactor tube based on pressures at the entrance and the exit of the reactor tube.

  • Patent number: 10093058
    Abstract: A method of forming an oral product includes extruding a mixture, conveying the extruded mixture through one or more pairs of forming rollers, and cutting the extruded mixture into one or more oral products. The mixture can include polymer and at least one flavorant, sweetener, active ingredient, or combination thereof. The extruded mixture forms an extrudate having a predetermined cross-sectional shape. The one or more pairs of forming rollers abut to define a passage there between as each forming roller rotates. The passage has a cross-sectional shape corresponding to the predetermined cross-sectional shape. The method can be performed using a machine including an extruder, one or more pairs of forming rollers, and a cutting device.

  • Patent number: 10071507
    Abstract: A method for manufacturing a composite part of an aircraft comprising the steps of placing a prepreg preform in a molding die between at least a molding die base part and a molding die upper part, debulking the air trapped in the prepreg, displacing the molding die upper part against the molding die base part in a direction perpendicular to the plane of the prepreg preform such that the molding die upper part presses the laminated perform until it reaches a blocking arrangement defining the position of the upper part relative to the base part for giving the prepreg preform the nominal thickness of the cured part, wherein said displacement is achieved by bolting the different parts of the molding die against each other, providing an elevated temperature to the preform such that it is cured.
