  • Patent number: 6673300
    Abstract: A method for plugging selected cell channels in a honeycomb structure for the fabrication of a solid particulate filter. The method includes covering a first end face of the honeycomb structure with a mask having openings corresponding to open ends of a first plurality of cell channels; loading powdered plugging material from through the mask openings into the first plurality of cell channels; forming plugs in the first plurality of cell channels at ends opposite the first end face of the honeycomb structure; loading powdered plugging material into the open ends of a second plurality of cell channels open at the second end face of the honeycomb structure; and forming plugs in the second plurality of cell channels at the ends adjacent the first end face of the honeycomb structure.
    Type: Grant

  • Patent number: 5612961
    Abstract: A method of verifying the baud rate for communication of data by an Asynchronous serial device residing within a data processing system. The data processing system having a first Asynchronous serial device and a second Asynchronous serial device. The first and second serial devices are connected one to another for communication of data therebetween. The first and second serial devices are initialized with a common baud rate for transmission and reception of data, respectively. A test sequence pattern is created, and transmitted at the common baud rate from the first serial device to the second serial device. The second serial device transmits the received test sequence pattern back to the first serial device. The test sequence pattern is then verified as either valid or invalid.

  • Patent number: 4612649
    Abstract: A process for refining metal in a crucible containing a layer of molten slag, wherein molten metal passes downwardly through the slag and resolidifies as an ingot thereunder. The slag is kept molten by passing electrical current through the slag layer and between a first electrode and a second electrode. The second electrode has liquid or gas cooling means as an integral part thereof. Current is passed between the first electrode and the second electrode through at least one electrically conductive member interposed between the slag and the second electrode. The electrically conductive member has a melting temperature above the melting temperature and below the bulk temperature of the slag. A portion of the surface of the electrically conductive member that is in contact with the slag has a temperature above the freezing temperature of the slag.
