Abstract: A method to clean the wellbore and the near wellbore formation adjacent to the wellbore of the gas bearing formation adjacent to the production zone of the wellbore. The method includes the steps of injecting a treatment liquid containing from 84.5 to 100% of liquid carbon dioxide, 0 to 15% of an alcohol, and 0 to 0.5% of a surfactant into the well in a predetermined quantity and maintaining the pressure of the treatment liquid in the near wellbore formation of the gas bearing formation below the fracturing pressure of the formation, releasing the pressure on the wellbore and allowing the liquid CO2 to vaporize and other materials to blow out of the well.

Abstract: A method of case hardening an article formed of titanium, zirconium or an alloy of titanium and/or zirconium is disclosed. First, the article is heat-treated in an oxidizing atmosphere at a temperature in the range of 700 to 1000° C. so as to form an oxide layer on the article. Then, the article is further heat-treated in a vacuum or in a neutral or inert atmosphere at a temperature in the range of 700 to 1000° C. so as to cause oxygen from the oxide layer to diffuse into the article.

The compositions include either a water-soluble polyalkylene glycol or a water-soluble polyalkylene oxide mixed with a polymer or copolymer comprising polyalkylene oxide having carboxylic acid-containing residues.

Abstract: An apparatus for lifting and stabilizing sunken or settled foundations, slabs, footings, etc. includes a lifting plate having a pipe section solidly secured thereto, for passing concentrically over the anchor pier used in such operations. The concentric lifting plate pipe precludes cocking or tilting of the plate relative to the anchor pier and foundation structure, thereby greatly improving the security of the lifting operation. As a result of the increased lifting plate stability provided by the present invention, only a single clamp is needed for securing the lifting assembly to the foundation. The clamp is adjustably positionable as required, to secure to a solid area of the foundation structure. The present system secures the plate to the pier using mechanical fasteners, thus precluding requirement for costly welding and other metal forming equipment. A method of raising or stabilizing a foundation or similar structure using the present apparatus, is also disclosed.

Abstract: In a CCD imager, a charge is accumulated in pixels of an image area representative of the intensity of incident radiation and is subsequently transferred to a store section and then on a row by row basis to an output register by applying suitable drive pulses to drive electrodes. Signal charge in the output register is transferred to a multiplication register by drive pulses applied to drive electrodes to give charge transfer in the direction shown by the arrows. One or more drive pulses applied to the electrodes of the multiplication register are of sufficiently large amplitude to produce high field regions in the register element to cause signal multiplication by impact ionisation. This gives a low noise amplification of the signal charge, the multiplied signal charge being detected at charge detection circuit.

Abstract: Described is an automatic control system for land (and possible marine) vehicles based on carrier phase differential GPS (CPGPS). The system relies on CPGPS to determine vehicle position and attitude very precisely (position to within 1 cm and attitude to within 0.1.degree.). A system incorporates a technique to calculate and compensate for antenna motion due to vehicle roll and pitch. One aspect of the system utilizes an intelligent vehicle controller that recognizes and adapts to changing conditions, such as vehicle speed, implements towed by the vehicle, soil conditions, and disturbance level. The system provides the capability to control the vehicle on various paths, including straight lines and arbitrary curves. Also described is a technique for initialization and vehicle control using only a single pseudolite.

Abstract: The present invention is a golf cup cutter sharpener. The sharpener consists of one or more grinding wheels affixed in a rigid housing. The grinding wheels are cylindrical metal elements covered by a removable, and thus replaceable, abrasive surface. The wheels are belt driven, and powered by a standard electrical motor. The grinding wheels are aligned according to the geometry of the sharpener. The angle of the wheels is chosen so as to provide the proper angle of grinding to create a sharp cutting edge. If two wheels are utilized, the wheels are positioned to contact two non-adjacent scallops of the sharpener. A mandrel holds the cup cutter in place while the sharpening operation is taking place.
