Patent number: 8891071Abstract: An apparatus comprising an encoded pressure signal propagating in a fluid flowing in a conduit. An optical fiber measurement element has a reflector on one end and is disposed around at least a portion of the conduit. A light source injects a second optical signal and a third optical signal propagating in first and second optical fibers, respectively. A delay section is disposed in the second optical fiber. The second optical signal and the third optical signal are directed into the optical fiber measurement element and are reflected back from the reflective end such that at least a portion of the reflected second and third optical signals propagate through the second and first optical fibers respectively to an optical detector. The optical detector senses an interference between the reflected optical signals and outputs a first signal related thereto.Type: GrantFiled: February 3, 2013Date of Patent: November 18, 2014Assignee: Halliburton Energy Services, Inc.Inventors: Ronald L Spross, Paul F Rodney, Neal G Skinner, James H Dudley, John L Maida, Jr.

Publication number: 20140284937Abstract: The system is a drilling bearing device. The device includes an outer body structure, and inner body structure, and a loading structure. The inner body structure is disposed at least partially within the outer body structure. The inner body structure moves relative to the outer body structure. The loading structure is disposed between the outer body structure and the inner body structure. The loading structure facilitates adjustment of a position of the inner body structure relative to the outer body structure relative to the outer body structure resulting from mechanical wear in the device. The loading structure substantially prevents displacement of the inner body structure relative to the outer body structure in response to a reciprocating displacement to maintain a substantially constant relative location.Type: ApplicationFiled: March 20, 2014Publication date: September 25, 2014Applicant: Oscilla Power Inc.Inventors: James H.
