Abstract: An automated apparatus for mixing ingredients stored in closed containers includes a gyroscopically mounted frame with a clamping arrangement for clamping a container therein. A shuttle moves back and forth between a conveyor and the frame carrying containers to and from the frame. An injection arm carried on the shuttle moves the container into the frame, and an ejection arm moves the container from the frame to the shuttle, for return to the conveyor. A braking alignment mechanism orients the frame to receive a container.

Abstract: Apparatus for making battery paste comprises a mixing chamber having a floor with a cylindrical upstanding side wall and a top cover. A mixing head is mounted for rotation in the chamber including at least one mulling wheel and at least one plow for moving the battery paste into the path of the mulling wheels. A cooling system is provided for the mixing chamber and its contents including a plenum chamber in direct contact with the underside of the mixing chamber floor for cooling the floor and a plurality of riser ducts extend upwardly from the plenum chamber in direct contact with the side wall. At the upper end of the risers deflectors are provided for directing a discharge of cooling air downwardly and inwardly of the upper end portion of the mixing chamber to cool the material. An exhaust system is provided for removing heat, moisture and fumes developed in the chamber and a liquid supply system is provided for additional material cooling and for washing the interior surfaces of the chamber.
