  • System and method for downloading code
    Publication number: 20020012347
    Abstract: A system and method for downloading code or other data to a group of remote units via a plurality of data paths. The data paths used for transmission may be selected based on the criticality of the code or data to the remote unit and the loss rate potential of each data path. The system and method may download the data using a carouselling technique.

  • Stirring molten metal
    Patent number: 4008884
    Abstract: For stirring molten metal such as aluminum in a furnace, metal is alternately withdrawn from and discharged as a jet into the body of molten metal, such being effected by successive application of suction and gaseous pressure to a tubular vessel which projects beneath the surface of the molten metal for advantageously delivering the successive quantities in a horizontal direction over a preferably long path. Effective, reliable stirring of the entire body of metal is achieved with one or more such means, the extent of stirring being controllable; the results include saving of energy and of time for furnace operation, and reduction of melt loss.
