摘要： A fluid-filled pipe is investigated by a non-intrusive procedure to determine whether the fluid is liquid or gaseous, whether it is flowing or static, the direction of flow if it is flowing, the approximate pressure if it is a gas, and the rate of flow if it is a gas. The results are obtained by applying a heater to the surface of the pipeline and measuring the upstream and downstream temperatures of the surface of the pipe wall before and after the beginning of the application of heat. Some of the data generated is compared with data from another source to assist in the determination of the characteristics to be ascertained.

摘要： An apparatus for measuring the work produced by a compressor comprises pressure sensors for measuring the suction and discharge pressures of the compressor and a device for measuring the operating speed of the compressor. The apparatus further comprises a data processor for receiving signals representative of the suction and discharge pressures of the compressor and its operating speed, and generating a signal representative of the work performed by the compressor during a predetermined time interval. Desirably, the data processor is designed to integrate the work output of the compressor over a series of time intervals to generate a cumulative horsepower-hour reading for the compressor over an extended period of time.

摘要： A digital read-out or indicator attachment for a utility meter which features a tensioned, flexible stranded cable connected at one end to a crank driven in rotation by the index of the meter and having an opposite remotely extending end connected to operate a digital counter located in a position remote from the meter. The cable is supported between the crank and the counter by a low friction sheath having a coefficient of thermal expansion approximately equal to that of the cable.

摘要： Buried fluid containing conduits, such as natural gas lines, are located by providing variable frequency sinusoidal excitation acoustic signals over a broad frequency range to the fluid content of the conduit so that the conduit will vibrate and cause elastic vibration in the media in which such conduit is buried. A plurality of measurements of said vibrations are taken on the surface of the media or ground in which such conduit is buried. The measurements are taken laterally of the estimated position of the conduit. The position of the conduit is determined by changes in the characteristics of the vibrations caused by the differences in distances between the pipe and the measurements.
