  • Method of making metal components
    Publication number: 20070020134
    Abstract: In order to create titanium components with a titanium composite insert, a method is provided whereby an initial pre form 1 has a groove 2 formed in it. An encapsulating member 4 is then provided about the groove 2 in order to create a cavity 5 which is filled with titanium alloy powder 6. This titanium alloy powder 6 is densified and then accurately machined in order to create a groove insert form 7 which can accommodate a titanium composite material pre form insert 8 and further titanium alloy powder 9 such that through a high temperature isostatic pressing (HIP) process, the insert 8 is embedded. The original component form 1 can then be machined in order to create the final component elements such as aerofoils 13.

  • Technique for sensing flow related parameters when using an electric submersible pumping system to produce a desired fluid
    Patent number: 6695052
    Abstract: An electric submersible pumping system having a downhole gauge section. The electric submersible pumping system comprises a submersible motor powered by a submersible pump. The submersible pump may be located below the submersible motor when in operation, while the downhole gauge section is disposed above the submersible motor. A power cable is coupled to the submersible motor through the downhole gauge section.
