Assignee:

Parker-Hannifin Corporation - Cleveland OH

International Classification:

B01D 53/22

US Classification:

96 8, 95 45, 95 52, 96 4, 96 7, 96 10

Abstract:

An air dryer having an internal orifice designed into an outlet end cap that eliminates the need for external valves or regulators to control the flow of air through the dryer. The internal orifice, which can be press-fit or threaded into the end cap, provides a consistent and stable outlet flow and dew point and eliminates the need for instruments to measure outlet flow and dew point. The orifice size can be easily changed for changing outlet flow and dew point. A protective tubular shroud is provided for shielding a membrane module of the dryer, and for routing sweep gas to a bottom vent.

Abstract:

Local exchange carriers (LECs) face increasingly stiff competition. The LECs provide interconnect services for many of the potentially competing carriers. To forecast business trends and manage its network, any carrier, particularly a LEC, needs to effectively estimate the size and revenue generating potentials of the business of the potentially competing carriers. In accord with the invention, monitor equipment on the one carrier's network forms detailed records from call related messages produced by that network for interconnect call traffic with another carrier's network. These records are loaded into a relational database. Preferably, a data preparation routine enhances the data, for example, by translating certain codes into text and by spreading usage data over predefined time intervals. An on-line analytical processing program runs one or more applications to analyze the interconnect traffic. The analysis provides traffic data regarding the current size and/or changes in the customer base of the other carrier.
