An apparatus and method for manufacturing plastic containers having RFID tags embedded therein is disclosed. The bottles are manufactured using a blow-molding technique wherein an in-mold film having an RFID tag embedded therein is positioned or placed against the parison immediately prior to the blow mold being closed and the pressurized air being used to inflate the parison. The resulting container thus has an RFID tag fused thereto to allow for tracking and tracing of the container after manufacture, as well as providing a mechanism by which the authenticity of the bottle can be verified.

A method is described for priming an in-line molten metal filtration unit having a porous ceramic or refractory filter mounted substantially horizontally in a filter box. This filter box has an inlet for molten metal and an outlet for molten metal, the outlet being a closeable outlet in an exit well connecting to the downstream side of the filter. The method of the invention comprises the steps of adding a molten metal to the filter box sufficient to entirely cover the upstream side of the filter with a depth of molten metal and temporarily sealing the outlet in the exit well. A steadily increasing vacuum is then applied to the closed exit well at a rate between 0.1 and 10 kPa per second by withdrawing a stream of air from the exit well by means of a fan or air venturi until molten metal begins to flow through the filter. At that point the vacuum is quickly released and the molten metal outlet is opened. Once the filter has been primed in this manner, flow of metal through the filter continues while requiring only a relatively low head of molten metal on the inlet side of the filter.

A B S T R A C T Ti and V impurities are removed from molten aluminium by adding a boron-bearing substance and agitating the aluminium in the presence of a dispersed chloride and/or fluoride flux active for fluxing (Ti,V)B2 particles. It is preferred to perform the process by stirring the molten aluminium to generate a vortex, into which aluminium fluoride is introduced as a fluxing agent and for reaction with any alkali metal impurity present in the molten metal. The alkali metal fluoaluminate thus generated assists the fluxing of the (Ti,V)B2, as does any cell electrolyte present in the molten aluminium.
