Abstract: Disclosed is a process for purifying groundwater by initially separating off solid constituents, adsorbing ethers and polycyclic aromatic hydrocarbons to an absorber resin, desorbing the adsorbed compounds with steam and regenerating the adsorbed resin with an acid.  The process enables ethers and polycyclic aromatic hydrocarbons to be separated off from polluted groundwater to such a substantial extent that the groundwater can be added to flowing surface waters without problem.  The purified water can, if appropriate, be used as cooling water or, after further biological purification, can also be used as drinking water.

Patent CA-2214325-A1 (CA)
Inventor: HUTLEY CHRISTOPHER GEORGE
IPC: E21B17/02
Filed: 1997-10-15
Abstract: In the oil industry, several types of survey tools are used to track the down hole locations of drilled wells and to track the location of a well that is being drilled in a direction other than straight vertical. Many of the survey tools used require a wireline to be attached for the survey signal to be sent back to the surface and also for the retrieval of the downhole survey tools. During drilling operations it is important to have the survey tools as close to the drilling bit as possible to establish where the bit is actually drilling. During drilling operations a new length of drill pipe must be added approximately every ten meters. This requires the wireline that is inside the drill pipe to be pulled to surface out of the way for the connection or addition of the new pipe. In recent years people have developed a system to break the wire in the drill pipe and establish a "Wet Connection" so you would not have to pull all the wireline out of the pipe and could leave the survey equipment down near the bit. All you would have to do is have your wire make connection to the wire that is in the pipe near the surface and use the fluid for the ground of the wire to establish a signal. Placing a splice in the wireline and mounting a male connector to the top of the wireline that will be left in the pipe allows the survey tools closer connection to the surface. A female end is then attached to the wireline to go over the male end to make the connection. By doing this you speed up your connections because you are not pulling the full length of the wireline each ten meters. This system works well when using a fluid that has a high level of conductivity like water, however many of the wells drilled now use specialized fluids that are not nearly as conductive. There is also a need sometimes to be connected in a gasified fluid that offers no conductivity for your ground. This system also occasionally is difficult to actually make the connection because the wetconnect is a small male pin pointing up and a female end that drops over often during drilling is pumped off because of the hydraulic pressure created. When the drill pipe is being rotated it loses the connection almost every time as well. This makes this type of connection unreliable for the data to be transferred up to surface. Serious problems can arise as a result of poor or faulty data being transmitted to the surface. Poor data has caused wells to be drilled in the wrong direction missing the entire area of interest.   The need for a connection that would be reliable in fluids, gasified fluids and in pure gases has become extremely important. The technical knowledge disclosed within this application relates to a mechanical device that is designed to make a positive wireline connection in a fluid. gasified fluid or in a pure gas environment and is able to rotate with the drill pipe.

Abstract: The present invention relates to a cooled platform for a gas turbine moving blade, and enables a platform to be cooled when the moving blade is cooled by steam.  The moving blade is provided with a plurality of steam passages.  Steam is introduced from the steam passage at the trailing edge portion, flows in a serpentine passage composed of other steam passages to cool the blade, and flows out to a blade root portion from a base portion of the steam passage at the leading edge portion, being recovered.  Part of steam flowing into the platform from the base portion of the steam passage at the trailing edge portion enters first and second steam passages in the platform.  On one side, the steam passes through first, third, and fourth steam passages, and on the other hand, the steam passes through second, fifth, and sixth steam passages.  The steam is recovered together with the steam having cooled the blade at the base portion of steam passage at the leading edge portion.  Therefore, the peripheral portion of platform can be cooled by steam, air is not needed, and the platform can be cooled by steam when the steam cooling system is used to cool the blade.
