Abstract: A  natural  gas  compression  heating  process  for regulating the operating temperature of the natural gas  flowing  through  long  pipelines  in  continuous permafrost and discontinuous permafrost regions.  The heat obtained through compression of the natural gas, instead   of   actually   heating  as   performed conventionally, is utilized to raise the temperature of the natural gas to only the desired operating temperature.    Consequently,  the  locations  of  the natural   gas   compression   heating   process   and compression stations  along  the  pipeline  in  a permafrost  region  are  determined  by  the  flowing temperature profile of the pipeline instead of the conventional standard compression cost versus pipeline diameter analysis.

IPC: H04L12/54
Filed: 1996-11-08
Granted: 2006-08-08
Abstract: The invention relates to a method for traffic control in a communication system transferring traffic units. The method comprises the steps of (a) maintaining a continuously changing quantity determining whether an individual traffic unit can be forwarded, (b) changing the value of said quantity so that a traffic density lower than a specific predetermined value changes the value of the quantity in a first direction but no more than up to a predetermined first limit, and a traffic density higher than said predetermined value changes the value in a second direction, and (c) beginning rejection of traffic units as the value of the quantity in said second direction reaches a specific predetermined second limit. In order to save the network bandwidth the value of the quantity is also changed at rejected traffic units in said second direction, but no more than up to a specific predetermined third limit (-D, H), and when the value of the quantity is between the second and the third limit, it must again alter in said first direction up to at least said second limit before traffic units are accepted.

A portion of the steam of the passage 10A is introduced from the impingement plate 25 to a steam sump 24 to cool the central portion of the inner shroud 21 and pass through the passage 10D to be recovered from the steam outlet port 12. On the other hand, cooling air is fed from cooling air feed ports 6 and 26 to peripheral portions of the outer and inner shrouds 1, 21, and is discharged to the outside from the rear sides thereof, respectively, and the cooling air is further fed from a cooling air feeding port 7 to the passage 10E on the rear edge of the blade to cool the rear edge of the blade. Only the narrow portions where it is difficult for the steam to pass are air-cooled to thereby reduce the amount of the cooling air.

Filed: 1999-02-11
Granted: 2006-09-05
Abstract: The present invention represents a new approach in the field of digitally demodulating a frequency modulated signal as it is used for example for fm-audio broadcasting.

According to the present invention the spikes in the demodulated signal which are typical to occur for carrier to noise ratios below the fm-threshold are detected and eliminated. The detection is done by interpolation and other criteria of the unwrapped phase .PHI.u of the frequency modulated signal. The unwrapped phase .PHI.u is calculated as the absolute phase which is not limited to the range [ -.eta., ..., .eta.].
