摘要： An enhancement of an electrically written memory element utilizing the motion of protons within a dielectric layer surrounded by layers on either side to confine the protons within the dielectric layer with electrode means attached to the surrounding layers to change the spatial position of the protons within the dielectric layer. The device is preferably constructed as a silicon-silicon dioxide-silicon layered structure with the protons being introduced to the structure during an anneal in an atmosphere containing hydrogen gas. Device operation is enhanced by concluding this anneal step with a sudden cooling. The device operates at low power, is preferably nonvolatile, is radiation tolerant, and is compatible with convention silicon MOS processing for integration with other microelectronics elements on the same silicon substrate.

摘要： A system to determine the mixture of fluids in the deviated section of a wellbore comprising at least one distributed temperature sensor adapted to measure the temperature profile along at least two levels of a vertical axis of the deviated section. Each distributed temperature sensor can be a fiber optic line functionally connected to a light source that may utilize optical time domain reflectometry to measure the temperature profile along the length of the fiber line. The temperature profiles at different positions along the vertical axis of the deviated wellbore enables the determination of the cross-sectional distribution of fluids flowing along the deviated section. Together with the fluid velocity of each of the fluids flowing along the deviated section, the cross-sectional fluid distribution enables the calculation of the flow rates of each of the fluids. The system may also be used in conjunction with a pipeline, such as a subsea pipeline, to determine the flow rates of fluids flowing therethrough.

摘要： A method and apparatus is disclosed for measuring the flow of fluid in the conduit, giving the example of oil in a well bore (12). A heat exchanger such as a cooling station (66) is placed in the well bore (12) and caused to create a slug of cooled oil whose passage, through the well (12) can be monitored by a temperature sensor in the form of a continuous fiber optic loop (62). Knowledge of the movement of the cooled slug of oil and of the free cross-section of the conduit (54) wherein the oil is flowing permits the volume flow-rate of oil to be calculated. Cooling stations (66) are cooled by Joule-Thompson cooling employing high pressure nitrogen gas. Cooling stations (66) may be placed at plural locations within the well bore (12) to monitor individual flows (68) from multiple flow sources.

摘要： A device that can be moved through a pipe to treat its interior surfaces with a washing or sealing fluid composition including a container with fluid under pressure and a conduit leading from the container to a rotary nozzle. The conduit terminates in a head that is fixed to the conduit and housed within the nozzle. The nozzle and head are spaced from one another and have one or more passages and ducts respectively, each of which extends laterally relative to the conduit. The passage in the head can be curved so that a turbine structure is formed and exiting fluid creates a force to assist in rotating the nozzle. The nozzle can also be rotated by a motor that is mounted on the conduit and in direct drive with the nozzle. Various rotatable nozzles can be interchanged with one another so that the interior of a pipe can be air cleaned, coated and/or wiped with a wiper blade or otherwise treated with a fluid material. Also, a probe attachment can be placed in communication with a duct of the nozzle to extend a feeler element under pressure and thus assist in detecting plugs and holes in the pipe. A TV camera is normally attached at the front end of the nozzle for viewing the action of the nozzle and/or probe.

摘要： A method of measuring fluid properties such as flow velocity, flow rate, and fluid composition comprises positioning a heat exchange element with a temperature sensor, such as an optical fiber temperature sensor, arranged centrally inside the element in thermal contact with a fluid of interest, heating or cooling the heat exchange element to cause a temperature difference and exchange of thermal energy between the element and the fluid, using the temperature sensor to measure the temperature of the heat exchange element during the exchange of thermal energy, and determining properties of the fluid from the temperature measurement. A second temperature sensor can be provided offset from the first sensor to provide additional measurements to improve accuracy, and a plurality of heat exchange elements with temperature sensors can be used together to determine fluid properties over a large region.
