Abstract: An apparatus for securely mounting an audio-visual equipment to virtually any external structure is presented. The apparatus includes a base wall with an upwardly extending sidewall on the left and right side, and terminating in outwardly extending flange at the end of each of said sidewall. The base wall includes an aperture at its geometric center for securing a pin or rod. The sidewall includes one or more apertures configured to accept a strap for secure fastening to an external structure. The flange includes one or more apertures configured to accept a screw as an alternate means for secure fastening of the apparatus to the external structure.

Abstract: A chamber having a discharge base discharges an oversize fraction of a material and a fine fraction of the material separately from the chamber. The discharge base for the chamber for the heat treatment of the material is capable of separating the fine fraction of the material from the oversize fraction of the material. The discharge base has a plurality of conveyor elements which are movable to and fro for the discharge of the oversize fraction of the material. The discharge base is also provided with separator openings for separating out the fine fraction of the material. The conveyor elements are of bar-shape construction and are disposed in parallel to one another on the discharge base to be moveable in the direction of their longitudinal extent, and the separator openings are formed by longitudinal gaps between the conveyor elements.
