    Abstract: A method of modeling a heat exchanger is disclosed and comprises assigning input temperatures, assumed output temperatures, and a set of flow rates, inputting the parameters into a set of equations arranged to calculate a heat transfer coefficient, inputting parameters into a second set of equations arranged to calculate output temperatures, substituting actual output temperatures for the assumed output temperatures, and again calculating the heat transfer cooefficient. The new heat transfer coefficient is then used to obtain revised actual output temperatures, and the initial actual output temperatures and the revised actual output temperatures are compared to determine whether they differ by less than a desired variance. If not, a new iteration is performed until the output temperatures converge.

    Abstract: A system detects abnormal conditions associated with a process plant. The system receives signal processing data generated by signal processing data collection blocks implemented by a plurality of devices. The signal processing data collection blocks may generate data such as statistical data, frequency analysis data, auto regression data, wavelets data, etc. The system includes an analysis engine configured to detect at least one abnormal condition associated with the process plant. The signal processing data is provided to the analysis engine, and the analysis engine determines if an action should be taken.

    Abstract: A dynamic registration device for a mailing system that reduces the problems of dust generation, ink smearing, and print head contact is provided. The biasing force normally applied to the back panel of a mail piece, such that the front panel maintains contact with a registration plate, is controlled by an actuator such that the force can be removed when the printing module is not performing the actual printing process. Thus, the biasing force can be applied only when the print head is actually printing and the biasing force can be removed once printing has been completed. In other embodiments utilizing multiple printing modules, when one of the printing modules is inactivated, the biasing force can be removed, and the mail pieces pass through the inactive printing module without being registered against the top registration plate.

    Abstract: A network device receives packets from a first network segment, time stamps the packets as they arrive, and transmits the packets to a second network segment. By time stamping packets as they arrive, stale packets can be identified and discarded. A stale packet is a packet that has been pending in the network device longer than an active timeout interval, which may be varied based on network traffic levels to conserve network bandwidth. Packets may also be discarded to conserve packet buffer memory in the network device. For example, when an incoming packet arrives and an output buffer in which the packet must be stored is full, the output buffer is scanned to identify and discard packets that have exceeded a minimum timeout interval, thereby allowing the incoming packet to be stored in the output buffer. Many network protocols initiate the retransmission of packets after a timeout interval has expired and an acknowledge packet has not been received. The present invention conserves network bandwidth by not transmitting stale packets that either will be ignored or redundant when network traffic becomes heavy. The present invention also conserves buffer memory by allowing broadcast and multicast packets to be stored in and transmitted from a single broadcast packet output buffer. The proper packet transmission order at each port is maintained by comparing the time stamp assigned to the broadcast packet when it arrived at the network device with the time stamps of the other packets in the output buffer. Finally, the present invention provides many opportunities for collecting statistics, such as the average latency, mean latency and standard deviation of the latency of packets processed by network device.

    Abstract: A document sorter/stacker apparatus includes a plurality of slotted disk assemblies respectively associated with bins or pockets in which high-speed transported documents are to be sorted and stacked. Each of the disk assemblies is selectively rotated to position its document capture slot either into or out of the transport path documents, thereby to enable either the routing of the document through that particular pocket or its passage to another pocket. When the leading end of a document is captured within the slot, the slotted disk assembly is rotated to feed the document into the corresponding pocket. The rim of the slotted disk assembly is in contact with a document transport belt and with an endless belt driven by the slotted disk assembly to urge the document into the pocket. After the document has been fed into the pocket, the endless belt urges the tail end of the document away from the slotted disk assembly and toward a backing plate where the documents are accumulated in a stacked configuration.
