Abstract: A stop boss formed on the handle of a pail may be simultaneously molded along with the pail and its handle by means of a pair of pivotable members which have free ends abutting together in a first pivoting position, and which are spaced from each other in a second pivoting position. The free ends cooperatively define between them a mold cavity for forming the stop boss on the rotatable handle. The pivotable members are adapted to occupy their first pivoting position while the mold assemblies close, and to pivot into the second, open pivoting position upon opening of the mold assembly and removal of the molded part to facilitate removal of the stop boss.

Abstract: Processes for coating concrete bricks with exposed surfaces having sharply delineated portions of contrasting color and/or texture by periodically and regularly forming atomized particles of a viscous cementitious slurry and directing same on to portions of surfaces of each of a plurality of green concrete bricks in groups located stationary in regular fashion for a brief period and thereafter firing the thus coated uncured brick. The processes include steps for rapidly and/or sequentially varying the colors applied to the different groups of bricks during successive cycles of coating the successively treated different groups of such brick.
