  • Patent number: 9279467
    Abstract: A method is disclosed for forming a brake rotor including a desired custom marking having a predetermined size and shape. The method includes applying a chemical treatment to a marking portion of a surface of the rotor. The marking portion has a size and shape corresponding to the predetermined size and shape of the desired custom marking. The chemical treatment is configured to affect, in a predetermined manner, an ability of a stimulus, to which the rotor is to be exposed, to alter properties of the rotor. The method also includes exposing the rotor, having the chemical treatment applied thereto, to the stimulus. The stimulus alters properties of the rotor at the marking portion differently than the stimulus alters properties of the rotor at other portions of the rotor adjacent the marking portion, thereby forming physical differences in the rotor, which, being visually perceptible, form the custom marking.

  • Patent number: 8788209
    Abstract: A method of determining rate and phase of fluid produced from or injected into a hydrocarbon well includes obtaining first temperature and pressure measurements from sensors at the well. The first temperature and pressure measurements are applied to a plurality of predictive well models to calculate an estimated value of fluid rate and phase composition from each of the predictive well models responsive to the temperature and pressure measurements. A first fluid rate and phase composition result is derived from the estimate value of fluid rate and phase composition from each of the predictive well models.

  • Publication number: 20130323525
    Abstract: An automotive product having a plurality of components coated with a refractory interface coating and method for making the same are provided. The automotive product may include at least a first component and a second component configured to interconnect and engage one another. The first component may be composed of a first high-density material. The second component may be formed of a second lower-density material. A refractory interface coating may be applied at the interconnection between the first and second components to provide an enhanced surface finish to limit friction, prevent metallurgical bonding between the first material and second material, provide a barrier against galvanic corrosion, and provide a thermal barrier between the first component and second component to guard against thermal deformation or change in dimension of the second component.

  • Patent number: 8412458
    Abstract: Physical models of wells are used to determine rate and phase composition for fluid produced from or injected into the wells on a near real time and continuous basis. The method can be used to alert operators or others of conditions in a well or field to permit more immediate response. The method can be more tolerant of sensor faults, sensor drift, anomalous data or other occurrences which could otherwise lead to incorrect output. More than one model can be used to permit a hierarchy of calculation such that the rate and phase determination is more tolerant of anomalous data. The calculated rate and phase values from one or more wells can be reconciled against facility data.
