Abstract: A plastic container and handling assembly are described to enable a plastic container to store heavy bulk materials while handling the container for transport or other purposes. A groove is formed in the region of the container for which support is desired and a metal bar of corresponding shape and size is placed in the groove. A metal support having a plate in abutment with the metal bar and overlying it as well as adjoining regions of the plastic container is welded at spaced apart places to the bar without causing melting of the plastic container to thus affix the support to the container. Several embodiments are described.

Abstract: An apparatus is described for blending solids in an efficient and uniform manner by rotating the apparatus about an axis. A container is provided with at least first and second baffle plates that are arranged in crossing relationship. The baffles have opposite guide surfaces which are oriented near parallel to the rotational axis so as to face the direction of rotation. The baffles are placed generally centrally inside the container and extend generally from the vicinity of one container side to the vicinity of the other side of the container. A significant improvement in the mixing of different solids is obtained.
