  • Publication number: 20200014255
    Abstract: A claw pole stator for a transversal flux motor includes a multiplicity of segments positioned next to one another along a circumferential direction for the annular claw pole stator. Each segment extends from an inner circumferential surface along a radial direction to an outer circumferential surface and is delimited in the circumferential direction by a first side surface and a second side surface and in an axial direction by a first end surface and a second end surface. Each segment is connected by the side surfaces to at least one other segment to form the annular claw pole stator. Segments positioned adjacent each other contact each other by a first contact surface on the first side surface or by a second contact surface on the second side surface and due to the contact surfaces form a form-locking connection in the circumferential direction.

    Abstract: Coke including additives that are accumulated at the yield points or in the regions surrounded by the yield points. For homogeneous distribution, the additives are continuously dosed into the delayed coker during the filling time. The dosing can be carried out by powdery blowing with an inert gas (nitrogen) or also distributed in a slurry consisting of the reaction components and a partial flow of the coker feed (vacuum resid, pytar, decant oil or coal-tar distillates). According to an advantageous form of embodiment, the additives may optionally have a diameter of between 0.05 mm and 5 mm, preferably between 1 mm and 3 mm. Advantageously, the additives can be selected from at least one of acetylene coke, fluid coke, flexi coke, shot coke, carbon black, non-graphitisable carbons (chars), non-graphitic anthracite, silicon carbide, titanium carbide, titanium diboride or mixtures thereof.
