  • Patent number: 7328600
    Abstract: A process and apparatus for extruding aluminum into products, wherein aluminum logs are first heated to a predetermined temperature in a furnace, then are cut into billets of predetermined lengths, and then the billets, while still hot, are extruded into predetermined products in an extruder. In the process, the logs are cut into billets with a cross cut circular saw immediately after the logs are heated and before the logs are permitted to cool to a temperature below a suitable extruding temperature. The circular saw is cooled and lubricated during the cutting to as to restrain the saw from sticking in the heated aluminum and so as to maintain the temperature of the log at the cut within a predetermined range wherein the aluminum is relatively easy to cut and waste is minimized.

  • Patent number: 7185480
    Abstract: A flexible band is tensioned between fingers, capable of gripping together, of a gripper. In the bunching of plant stems, the band is held in an opening between fingers of the gripper behind a pair of rollers. The plant stems are carried along between the pair of rollers and received in the flexible band. After a bunch has thus been gathered, the ends of the fingers are brought towards each other, and the stems in the gripper are moved away from the rollers. Subsequently, the stems are tied together.
