Abstract: An apparatus for producing core assemblies that are used in particular for casting engine blocks and cylinder heads in a foundry. The apparatus includes a shooting station in which the individual cores are shot in a tool (3), and a withdrawal station (1) from which the cores are taken out and transferred for assembly to an assembly line (2). Different cores can be produced with different tools (3), and manipulators (4, 5, 6) are associated to the assembly line for taking the cores out of the opened tools (3), for handling and/or treating the cores, and finally for assembling and removing the resulting core assemblies.

Abstract: A mobile system and process for manufacturing cement additives and/or concrete admixture products comprises at least two tanks each containing a different raw material for manufacturing cement additives or concrete admixtures; a frame for mounting and transporting as an integral unit at least two pumps operative to transfer the raw materials into a blender which mixes the raw materials together to provide a cement additive or concrete admixture for dispensing at the destination site, which could be the manufacturer's new or remote manufacturing site, or even a customer's site such as a cement plant or a ready-mix concrete plant. The frame can be placed upon or attached to wheels, as in a truck or trailer frame, and the tanks may also be placed on or secured to the truck or trailer frame. A preferred skid-mounted system comprises pumps, valves, meters, and a computer processor unit which can control the equipment and permit adjustments to be made at the destination site.
