  • Patent number: 9180557
    Abstract: This invention provides an improved replacement nozzle configuration. The nozzle is provided in two pieces. A first nozzle piece is a relatively thin-walled cylinder that is inserted into the counterbored opening of a pressure vessel after the protruding portion of the original nozzle has been removed. A weld pad is attached to the pressure vessel, to which the first replacement nozzle piece is welded. Due to the reduced dimensions of the thin-walled first nozzle portion, a much smaller weld pad and pad-to-nozzle weld can be used. A second nozzle piece is positioned within the first nozzle piece and welded thereto. The existing instrumentation piping is connected to the free end of the second nozzle piece. This two-piece replacement nozzle can be implemented in approximately half the time required for the one-piece design.

  • Patent number: 8308199
    Abstract: A gap sub assembly can be used to form an electrical isolation in a drill string, across which a voltage is applied to generate a carrier signal for an electromagnetic (EM) telemetry system. The assembly comprises two conductive generally cylindrical components fashioned with a matching set of male and female rounded coarse threads, held such that a relatively uniform interstitial space is formed in the overlap space between them. The third component is a substantially dielectric electrical isolator component placed into the gap between the threads that effectively electrically isolates the two conductive components. Injecting the dielectric material under high pressure forms a tight bond resistant to the ingress of conductive drilling fluids (liquids, gases or foam), thus forming a high pressure insulating seal.

  • Patent number: 8127801
    Abstract: A cryogenic material transfer system incorporates a pipe-in-pipe configuration with a nanoporous or microporous insulating layer filling the annulus between the inner and outer pipe. The insulating layer is of sufficient flexibility to absorb and expansion or contraction of the inner pipe due to the flow of cryogenic material therethrough. For longer transfer systems a bulkhead is provided between adjacent pipe joints. Intermediately of the pipe joints an additional bulkhead may be employed to provide additional sealing or water stops and for providing provide additional load transfer. A fiber optic sensor system is installed in the annuals between the inner and outer pipe.

  • Patent number: 8104446
    Abstract: Screw holes are provided on a contacting surface of an insulator so as to enable a carburetor to be mounted on the insulator at a plurality of positions rotated about an axial center of an intake hole. The insulator is mounted on a cylinder at a predetermined position while the carburetor is mounted on the insulator by inserting bolts for mounting the carburetor into the screw holes through through holes of the carburetor. Accordingly, the carburetor can be mounted at a plurality of positions rotated about the axial center of intake holes relative to an engine body. Thus, a protruding direction of a throttle lever from the carburetor, i.e., an operating direction of the throttle lever, can be changed.

  • Publication number: 20110198839
    Abstract: A one-piece shaped aluminum or stainless steel half fitting for an insulated pipe. The method may include cutting a predetermined sized blank from material stock. A top and a corresponding bottom die may be installed into a press along with a matching press plate. The predetermined sized blank may then be inserted onto the press plate and aligned with locating marks on the press plate. Once the blank is installed properly into the press, the method may further include cooperatively bringing the top and bottom dies together to press the blank into a specifically shaped half fitting. When pressed, excess flange material may be created along the perimeter of the fitting shape and excess end portion material is created at end portions of the fitting shape. The top die may then be separated from said bottom die and the shaped half fitting may then be removed from the press. The method may further include trimming the excess flange material and excess end portion material from the shaped half fitting.

  • Patent number: 7900968
    Abstract: A gap sub assembly can be used to form an electrical isolation in a drill string, across which a voltage is applied to generate a carrier signal for an electromagnetic (EM) telemetry system. The assembly comprises two conductive generally cylindrical components fashioned with a matching set of male and female rounded coarse threads, held such that a relatively uniform interstitial space is formed in the overlap space between them. The third component is a substantially dielectric electrical isolator component placed into the gap between the threads that effectively electrically isolates the two conductive components. Injecting the dielectric material under high pressure forms a tight bond resistant to the ingress of conductive drilling fluids (liquids, gases or foam), thus forming a high pressure insulating seal.

  • Publication number: 20100319888
    Abstract: A heat exchanger for cooling reaction gas. A cooled tube receives hot reaction gas from a hot, uncooled tube. The cooled tube comprises a cooled inner tube and a tubular jacket that extends about the inner tube. A tubular connection is disposed between the uncooled and the cooled tubes, and includes a fork-shaped inlet head via which the inner tube is in communication with the uncooled tube. The inlet head is provided with an outer tubular section and an inner tubular section between which is disposed an intermediate space filled with heat-insulating material. The outer tubular section is connected to the tubular jacket. The inner tubular section is spaced slightly axially from the inner tube and is provided with an edge region that juts outwardly and is spaced slightly axially from the inner tube, this slight axial spacing being equal to or less than a maximum thermal expansion of the inlet head.

  • Patent number: 7854236
    Abstract: Method of assembling a vacuum insulated piping run for conducting a cryogenic fluid in which piping sections are produced in a first location and then assembled in a second location into a piping run. Each of the piping sections incorporates an outer cylindrical casing and an inner pipe for transport of the cryogenic fluid to form an inner annular region for containing insulation that can be radiation shield insulation and aerogel blankets. The piping sections are joined by welding the ends of the inner pipes together and then joining the outer cylindrical casing by a shell-like section. Points of connections are tested by vacuum testing techniques as each of the connections is made. Thereafter, the annular region is purged with a condensable gas such as carbon dioxide and subjected to a subatmospheric pressure.
