Abstract: A cable-coating extruder head having a head body with a central passageway for an advancing cable, a die insert removably seated in a fixed die body at the forward end of the passageway providing a die aperture through which the cable passes, and a guider insert removably mounted in a fixed guider body within the passageway for centering the cable in the die aperture, wherein both the guide insert and the die insert are insertable forwardly and removable rearwardly through the rearward end of the passageway to enable change of guider and die apertures without displacing the forward end of the head body. The guider insert has a rearward extension projecting beyond the head body for manipulation to facilitate guider insert removal and replacement.

Abstract: The disclosed system and method allow an artist to blend a desired color from available source (i.e., menu) colors and use the resulting blend color at the desired part of the picture and/or store the blend color for future use as a source color. A palette mixing area and a menu of colors can be displayed on a video screen. A signal defining a selected source color is generated when the artist touches with a stylus an area on a touch tablet which corresponds to the screen display of the selected color. When the stylus then touches the part of the touch tablet corresponding to a selected part of the palette mixing area on the screen, the screen shows at that selected area a blend of any color preexisting there and the selected color. A signal defining the blend color can be stored for future use as a source color. The proportions of the two colors in a blend can be controlled by stylus pressure, number of overstrokes and/or stylus dwell time.

Abstract: In the production of alloys, particularly Al alloys, by a continuous casting process a supplementary alloy stream is continuously fed into a main metal stream running to the casting mould. The supplementary alloy stream preferably amounts to 1-20% of the main metal stream and has a liquidus temperature above the temperature of the main metal stream so that on contact with the main metal stream, intermetallic phases are precipitated very rapidly as a result of the high chill rates.This mode of casting reduces the risk of coarse primary particles when casting alloys of high alloying element content. The supplementary alloy stream need not be based on the same metal as the main metal stream. The method is considered suitable for the addition of various metals, such as Zr, Mn, Cu, Fe, to aluminium and aluminium alloys to overcome a variety of difficulties and to produce alloy products of improved properties.

To minimize current leakage, the intermediate bipolar electrodes preferably almost completely surround the anode including the edges and the bottom.In operation, a metal/electrolyte mixture is swept up the interelectrode spaces by generated chlorine gas and spills out over the cathode into a duct 20 behind the cathode, the duct including a restricted passage 58 for degassing and an inverted channel 62 to collect product metal and convey it to a metal collection chamber 18.The electrolyte surface is preferably maintained to about the level of the top edges of the intermediate bipolar electrodes by means of a level control device 22 submerged in electrolyte in the metal collection chamber.

Abstract: 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)B.sub.2 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)B.sub.2, as does any cell electrolyte present in the molten aluminium.
