Abstract: A non-public, industry-specific computer network, for interconnecting a plurality of network members across an asynchronous transfer mode (ATM) system, is provided, including a plurality of network members. Each network member includes an on-site and an off-site information server. The on-site information server of each network member is located at a site of the network member, and the off-site information server of each network member is located at an administrator site. The network also includes a dedicated, high speed ATM communication backbone interconnecting the on-site and off-site information servers of each of the network members. An administration server is located at the administrator site and is connectable to the off-site information servers of each of the network members at the administrator site. The administration server transmits data received from one network member to one or more other network members.

Abstract: An on-board treatment device and method for use on watercraft and other mobile vessels are provided. The system includes a treatment tank which is connected to the head and a bioreactor and a feed pump which are connected to the treatment tank. A macerator pump breaks up solids in the wastewater before the wastewater enters the treatment tank. During a treatment cycle, a head valve prevents any further flow of wastewater from the head into the treatment tank. Also during a treatment cycle, a bioreactor 3-way valve will be set so that the feed pump will flow wastewater from the tank, through the bioreactor, and back into the treatment tank. The bioreactor will include microorganisms which are adapted to the treatment of human waste. When the wastewater has been sufficiently treated, the feed pump will be turned off so that solids in the wastewater can settle out.

Abstract: A gas chromatograph and method of chromatography are provided. Analytes, those compounds to be tested, are extracted from the sample by moving the sample into a column which has a stationary phase along the column walls. The column has two sections which are different in length. The longer section is heated and the analytes move to the shorter section. The longer section is then cooled and the entire column is heated. The device then functions as an analytical column and the analytes move out of the shorter section, through the longer section, and out of the column. A detector placed at the end of the column's longer section detects the presence of the compounds as they exit the column. In an alternate embodiment two separate columns are provided. One column is used as the extraction column and the other is used as the analytical column.
