Abstract: The brake disk according to the invention has on the nave a supporting ring ith radial depressions. Parts of the disk rim engage in a limited radially displaceable way in these depressions, but are mounted with a form fit in the direction of torque. The nave consists of material of higher tensile strength than the material of the disk rim, and the disk rim is fixed on the nave by composite casting. Different coefficients of expansion are thereby accommodated.

Abstract: A wheel for rail vehicles with at least one disc which is connected to an axle, and with a wheel rim having a tread or surface surrounding the disc, while the rail tread in engagement with the rim tread results in contacting points of the wheel during straight forward drive of the vehicle located on the tread or track of the rails. At least within that region of the rim which contains the above mentioned rail contacting points of the wheel rim the wheel rim is turnably connected to the disc for turning about an imaginary axis located in about the driving direction of the wheel.

Abstract: A bunker discharge apparatus, especially for bulk material. The apparatus includes conveyor elements having a ladder form or shape and extending parallel to each other and movable back and forth, by way of a drive, in the conveying or feeding direction. The elements include rungs or crossbars arranged transverse to the conveying direction and wedge-shaped in cross section. The crossbars have a stroke or pusher surface at right angles in the conveyor direction to shear and push bulk material to discharge; counter to the conveying direction, the crossbars have a flat-inclined wedge surface which returns to starting location with minimum displacement of bulk material. A drop-out or discharge connection or connecting piece having a conveying element and arranged at right angles is provided below the ladder-formed conveying elements.

Abstract: A silo for pourable material, especially heavy-flowing chemical and mineral substances with an upper charging station and at least one lower withdrawing station, according to which additional friction walls are in vertically spaced superimposed arrangement provided on the inner silo wall and are inclined downwardly relative to horizontal planes while being provided with passages therethrough for the passage of silo material therethrough, the angle of inclination of the friction walls being at every area thereof greater than the specific pouring angle of the respective pourable material in the silo.

Abstract: A silo, or bin, for flowable materials, especially heavy particulate solid materials. The bin has a bottom wall with a cylindrical wall upstanding therefrom. The bottom wall has a radial discharge opening formed therein and a rotor positioned above the bottom wall sweeps material into the opening. The bin has a guiding body on the axis which tapers in the downward direction and mounted inside the bin side wall are brake members which incline downwardly toward the axis of the bin and are preferably within the axial range of the guiding body.
