    摘要: A heat exchanger is illustrated in the form of a pair of juxtaposed chambers defining a first flow path for passing a heated fluid therethrough and a second flow path for passing a cooling medium therethrough. A heat exchanging structure extends between the first and second flow paths in communication therewith. The heat exchanging structure includes at least one composite of thermally conductive fibrous material laid up unidirectionally in a direction between the flow paths for transferring heat from the heated fluid in the first flow path for absorption by the cooling medium in the second flow path.

    摘要: A suppression system provides more effective protection for communication stations with distributed radio and power systems. The suppression system provides surge protection both locally close to the radio station building where the power plant and telecommunication equipment are located and remotely next to the radios and antennas located outside of the building on the communication tower. Local and remote suppression units may include monitor circuitry that monitor remote and local DC voltage levels and alarm conditions. The alarm conditions may include over-voltage protection failures, intrusions, and/or water infiltration. Displays on both the local and remote suppression units identify the voltage levels and alarm conditions.

    摘要: Calls made to a communication unit from the telephone network include a code which can be appended as a predetermined prefix or suffix to the units address code, for alerting the operator that the call was made from the telephone network. Conversely, calls made to the communication unit from another communication unit do not include the code thereby alerting the operator that the call was made from a communication unit. The alert can be accomplished by using visual indicators or and alphanumeric display and/or can be accomplished by use of two distinct audible signal.
