  • Patent number: 11220720
    Abstract: Embodiments of the present invention comprise; annealing steel sheets (e.g., hot rolled steel sheets or thin cast strip steel); cold rolling the sheets in one or more cold rolling steps (e.g., with annealing steps between multiple cold rolling steps); and performing one or more of tension leveling, a rough rolling, or a coating process on the sheets after cold rolling, without an intermediate annealing step between the final cold rolling step and the tension leveling, the rough rolling, or the coating process, or the customer stamping or final customer annealing. In order to achieve the desired properties for the steel sheet, stamping and final annealing is performed by the customer. The new process provides an electrical steel with the similar, same, or better magnetic properties than an electrical steel manufactured using the traditional processing that utilizes an intermediate annealing step after cold rolling and before the stamping and final annealing.

  • Patent number: 11219881
    Abstract: A method of regenerating an activated carbon catalyst which is used in the production of polysulphide liquor. In the method, the catalyst is washed with a washing liquid in order to remove the sediment accumulated in the catalyst. According to the present invention, in this case, the activated carbon catalyst is regenerated most suitably by bringing it to a multi-stage washing which comprises at least one washing step in which the washing liquid used comprises sodium sulphide, and one washing step in which acidic washing liquid is used. The sulphur precipitate is peeled off using sodium sulphide, and the iron and other metals can be effectively removed by using an acidic washing, without damaging the catalyst.

  • Patent number: 11203062
    Abstract: Three dimensional “green” parts are formed by combining sheet layers comprising metal powder bound together by a polymer. The “green” parts are then sintered to drive off the polymer and consolidate the metal powder to produce a monolithic metal part. Particularly, the invention is directed to processes for forming and stacking the shaped sheet layers that are readily automated and preserve the high value powder metal and polymer sheet trim scrap for reuse resulting in an additive overall process with little material waste. The invention includes processes in which “green” elements formed by methods such as three dimensional printing are incorporated into the “green” stack and become an integral part of the final sintered part. It further includes processes in which “green” sheet layers are shaped by methods such as hot bending or vacuum forming to provide three dimensional part features.

    Abstract: Carbonaceous-containing material including biomass, municipal solid waste, and/or coal and/or contaminated soil, and/or other carbonaceous materials may be gasified at low temperatures utilizing a reactor designed to generate shockwaves in a supersonic gaseous vortex. Preprocessed waste may be introduced into the reactor. A gas stream may be introduced substantially tangentially to an inner surface of a chamber of the reactor to generate a gaseous vortex rotating about a longitudinal axis within the chamber. The gas stream may be introduced using a nozzle that accelerates the gas stream to a supersonic velocity, and may impinge on an impactor positioned within the reactor chamber. A frequency of shockwaves emitted from the nozzle into the gaseous vortex may be controlled. The processed waste discharged from the reactor, which may include a gas component and at least a solid component, can be subjected to separation, and at least some of the gas component and at least one solid component (i.e.
