Abstract: An apparatus for batch coating liquid onto core pieces of particulate matter said apparatus having a processing mode and a discharge mode, and comprising a rotatable drum having a substantially right cylindrical shape, a horizontally disposed longitudinal axis, an interior surface, an exterior surface, a loading end and a discharge end, a loading opening at said loading end and a discharge opening at said discharge end, and farther having a frame for supporting said drum, drive means for rotating said drum about its longitudinal axis in a processing direction and oppositely in a discharge direction, at least one nozzle for introducing a spray pattern of liquid or gas into the drum, and a plurality of vanes affixed to the interior surface of said drum, said vanes configured to move the core pieces toward the loading end of said drum during processing and to produce a continuous cascade of core pieces over said vanes and into the spray pattern.

Abstract: A lightweight, folding copy stand, also of use as a sheet music holder or a book holder, comprised of a plurality of panels and hinges arranged such that the stand is erected with a minimum of steps and with desirable rigidity. The stand is also returned to a folded position with minimal effort and with a minimum of steps. When the stand is in its operational configuration, the plurality of panels and hinges form a support member, a shelf, an angular portion, and feet members. The angular portion and feet members may be integrally formed. When closed, the support member and shelf fold to form two exterior panels enclosing the feet members and defining an exterior surface area approximately one-half the size of the support member and four panels in thickness. In its closed configuration, the stand is approximately the size and weight of a typical magazine.
