Title: Natural gas compression heating process
Inventor: METZ MICHAEL C
IPC: F17D1/07
Filed: 1998-04-22
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.

Patent CA-2243967-A1 (CA)
Title: Data transmission using carrierless qam
Inventor: COOK JOHN WOLSEY
IPC: H04L25/49
Filed: 1997-03-11
Abstract: Carrierless signals of first and second channels pass via filters having quadrature responses and are then added for transmission.

Title: Internet file system
Inventor: RAO CHUNG-HWA HERMAN
IPC: G06F17/30
Filed: 1997-06-06
Abstract: A method and a system in which a computing system transparently accesses resources connected to the Internet. A memory of the computing system contains an operating system, a cache associated with the operating system, a shared library and an access server. The shared library is responsive to a system call for a file by determining whether a path name for the file is located under a personal name space in the memory and by issuing a request for retrieving the file from an Internet resource based on the path name located under the personal name space when the file is not stored in the cache and has a path name located under the personal name space. An access server, in response to the request from the shared library, selects an appropriate access protocol for retrieving the file from the Internet resource and retrieves the file from the Internet resource. The shared library then issues the system call to the operating system when the access server retrieves the file. The access server restores the file to the Internet resource when the application closes the file.
