  • Patent number: 6499546
    Abstract: The present invention relates to the use of a buffered acid wash to reduce the amount of oil in cuttings associated with the use of an invert emulsion well fluid. The buffered acid wash is sufficiently acidic as to convert all of the surfactant in the invert oil emulsion from one charge species into another, but substantially prevents the fluid from becoming so acidic as to generate carbon dioxide.

  • Patent number: 6499540
    Abstract: A method for detecting a leak in a drill string valve used when drilling a subsea well. The method comprises measuring a first inlet pressure at a subsea mudlift pump while a subsea mudlift pump and a surface pump are operating and before a well is fully shut-in and measuring a second inlet pressure at the subsea mudlift pump after the mudlift pump and the surface pump are shut down and after the well is fully shut-in. The first and second subsea mudlift pump inlet pressure measurements are then compared, and a check is performed to determine if the subsea mudlift pump inlet pressure has increased by an amount greater than an estimated annular friction pressure.

  • Patent number: 6498940
    Abstract: A telephone dialling apparatus appends an end-of-dialling signal, for example a “SEND” signal, to a dialled telephone number by determining from first and second dialled digits how many digits constitute a telephone number to be subsequently dialled. After the dialling apparatus has determined that the correct number of digits have been dialled, it automatically appends the end-of-dialling signal to the telephone number. The dialling apparatus may be used in a system in which a fixed line telephone is connected to a mobile network via a fixed access unit.

  • Patent number: 6497791
    Abstract: A pre-treatment device for wood chips for pulping comprises a tube through which the wood chips fall into a digester. Steam is injected into the tube through rings of nozzles, which are angled circumferentially to impart a rotary and turbulent motion to the falling chips. Some nozzles are angled downwardly to encourage the chips to flow freely through the tube, some are horizontal to encourage a longer dwell time near the nozzles. Digesting liquor is also sprayed onto the chips from spray nozzles after the first ring of steam nozzles. The heat and steam expel air and other non-condensable gases and volatiles from the chips, allowing them to absorb the liquor. At the bottom of the tube, the chips are propelled down and outwards by jets of higher-pressure steam, spreading and packing them into the digester.

  • Patent number: 6497546
    Abstract: A grain wagon includes a wheel supported frame on which is mounted a hopper or container for receiving grain, and the wagon is pulled by a tow vehicle or tractor. An inclined discharge auger conveyor has an outer section which folds between a stored position and an operating position projecting upwardly and forwardly and laterally outwardly from the container. The outer auger section has a pivotal discharge spout with a pivotal internal baffle, and the spout is actuated by a double acting hydraulic cylinder controllable through hydraulic lines from the cab of the tractor so that the tractor operator may fully load and “top off” the grain within an adjacent semi-trailer as the tractor operator pulls the wagon along the side of the semi-trailer. In one embodiment, the outer section of the auger conveyor has an outer telescopic housing extension which carries the discharge spout and extends and retracts automatically with folding of the outer auger conveyor section.

  • Publication number: 20020182135
    Abstract: In ridding fluids, including hydrocarbon fluids, both gaseous and liquid, of sulfur compounds including hydrogen sulfide, oxides of sulfur, and thiols, the present invention uses a small quantity of an activator, generally a noble metal oxide, preferably a copper species and/or a manganese species, along with a known oxide product, such as iron oxide, iron hydroxide, zinc oxide, zinc hydroxide, manganese oxide, manganese hydroxide, or combinations thereof, to thoroughly remove sulfur contaminants in a short amount of time. The activator allows for the use of smaller reactor vessels and the production of hydrocarbon fluids substantially free of sulfur products.

  • Publication number: 20020184189
    Abstract: An electronic book on a computer readable medium, e.g., a CD or the like, has “real-life” pre-recorded audio (preferably, in MP3 format) and visual text (preferably, in RTF format) seamlessly linked together via a linking file (preferably, in XML format) such that a reader can switch back and forth “at will” between visually reading on a computer display screen and/or listening to the book being read aloud by an actual narrator. The computer readable medium includes a reader program installed thereon and an automatic installation program. A novel process for creating the electronic book includes a creator program that may have a similar graphical user interface to the reader program. The electronic book may combine advantages of physical hard-cover books with new e-reading functionality developed by the present inventor.

  • Patent number: 6490449
    Abstract: A system and method of providing an intelligent automatic roaming analysis (ARA) that enables a roaming mobile subscriber to use abbreviated dialing regardless of the location of the subscriber in a radio telecommunications network. The radio telecommunications network includes a home network which comprises a Home Location Register (HLR) and a Service Control Point (SCP). The visited exchanges of the network are categorized by a type indicator if located outside the home service area. Subscription data and operator service data are provided as a database in the SCP, wherein applicable telephone codes are available for the home network and the visited exchanges. Based on the type of the visited exchange, an abbreviated number is rebuilt into an appropriate called party number (B-number) by utilizing one or more services provided in the SCP.

  • Patent number: 6490499
    Abstract: The method is suitable for the micromachining of accurately aligned holes in the aerofoil surface of a component such as a jet engine turbine blade or vane which comprises a ground anchorage portion and a cast aerofoil portion. The method uses a laser machining apparatus which is preprogrammed to machine holes in the aerofoil surface when that surface is in a predefined reference position and orientation in the apparatus. Initially the component is mounted in the laser machining apparatus by means of its anchorage portion. At least one probe is then moved over the surface of the cast aerofoil portion to derive the positions of selected points on that aerofoil portion. From the derived position data, angular and linear offset data may be calculated to define the deviation of that cast aerofoil portion from the reference position and orientation defined in the computer memory of the laser machining apparatus.
