Patent CA-2367179-A1 (CA)
Inventor: HAGIWARA TERUHIKO
IPC: G01V3/28
Filed: 2002-01-09
Abstract: A method of compensating for tool motion is disclosed. In one embodiment, the method includes passing a logging tool through a borehole, obtaining a series of tool response measurements, and obtaining a series of tool position measurements associated with the tool response measurements. The tool position measurements preferably indicate the distance between the tool axis and the borehole axis. The tool position measurements are preferably examined to determine if the tool was moving while the tool was making measurements. For measurements made while the tool was moving, the measurement time interval is preferably divided into subintervals each having a corresponding tool position. A formation property (such as resistivity) is estimated, and the expected tool response for each tool position is calculated. The expected tool responses are combined to form a model tool response, that is, the tool response that might be expected for a tool in motion. The model tool response is then compared to the measured tool response. The estimate of the formation property is adjusted and the process is repeated until the model tool response is substantially equal to the measured tool response.

Title: Methods of replacing water and cyclohexanone with acetic acid in aqueous solutions of catalyst
Inventor: DECOSTER DAVID C
IPC: C07C45/84
Filed: 2000-04-19
Abstract: This invention relates to methods of replacing water and cyclohexanone with acetic acid in an aqueous solution of catalyst, preferably a cobalt compound.  Such an aqueous solution is produced by extracting catalyst with water from a cyclohexanone/water solution of reaction products made by the direct oxidation of cyclohexane to adipic acid. The replacement of both water and cyclohexanone are conducted in a solvent exchange column, wherein acetic acid dissolves the catalyst, while water vapors force the cyclohexanone into a condenser, followed by a decanter wherein two liquid phases may be formed and separated;  an upper liquid phase containing a majority of cyclohexanone and a lower liquid phase containing a majority of water. The cyclohexanone may be removed in a pre-treatment zone, wherein also part of the water may be removed, before the concentrated catalyst extract enters the solvent exchange column.

Patent CA-2373632-A1 (CA)
Inventor: SMYTH JOSEPH
IPC: H04L12/56
Filed: 2000-06-27
Abstract: A received data stream is formed into a stream of packets, each packet comprising a payload section of data and an overhead section. In forming the packets, a template overhead section is created for use by the stream of packets and this template is applied to the data to form the packets. This avoids the need to individually pass packets through a routing stack, thus reducing the processing demands on the processor which constructs the data packets and reducing the transmission delay experienced by data. The template overhead section can be formed by sending a packet through a routing stack.  Another aspect describes apparatus for processing packets where a first processor processes signalling packets and a second processor processes real-time data packets. The first processor can be used to create the template overhead section before passing the template information to the second processor where it can be used in forming the real-time data packets.
