    Abstract: A predetermined multiphase flow anomaly, for example, a plug, a slug, or a pseudo-slug, in a pipeline may be identified by identifying an analysis pipe section containing a multiphase fluid flow, measuring a first differential pressure at a first pair of pressure measuring points positioned along the analysis pipe section, measuring a second differential pressure at a second pair of pressure measuring points positioned along the analysis pipe section, identifying a primary drop in the first differential pressure and a secondary drop in the second differential pressure, measuring a time delay between initiation of the primary pressure drop and initiation of the secondary pressure drop, and determining as a function of the time delay whether the primary pressure drop corresponds to a predetermined multiphase flow anomaly moving through the pipe analysis section.

    Abstract: A microminiature Stirling cycle engine or cooler is formed utilizing semiconductor, planar processing techniques. Such a Stirling cycle thermomechanical transducer has silicon end plates (14, 22) and an intermediate regenerator (50). The end plates (14, 22) are formed with diaphragms (34, 44) and backspaces (32, 42), one end plate (14) forming the expansion end and the opposite end plate (22) forming the compression end, with the regenerator (50) bonded in between. A control circuit apparatus is linked to the diaphragms (34, 44) for controlling the amplitude, phase and frequency of their deflections. The control circuit apparatus is adapted to operate the transducer above 500 Hz and the passages and the workspace, including those within the regenerator (50), expansion space (30) and compression space (40), are sufficiently narrow to provide a characteristic Womersley number, which is characteristic of the irreversibilities generated by the oscillating flow of the working fluid in the workspace, below substantially 5 at the operating frequency above 500 Hz.

    Abstract: A method is disclosed for removing dissolved oxygen from water containing zebra mussels. An apparatus for carrying out the method is also disclosed. Oxygen is removed from water to a level below that which is sufficient to support the survival respiration of the zebra mussels. A flow of water (6) from inlet conduit (3) enters a vacuum chamber (2) which is adapted to maintain an air space (5) above water (6). A vacuum pump (7) maintains a vacuum in air space (5) so as to extract dissolved gases, including oxygen, from water (6). An agitation device (8) and a dissolved oxygen sensor (9) may be included within the vacuum chamber (2). An additional vacuum unit (20) may be used to increase the throughput and discharge rate of water entering and leaving the system.

    Abstract: The present invention relates to an improved sample injector (4) for use in gas chromatography. The invention also includes a method of injecting a sample onto a chromatographic column (2), and a method of analyzing a sample using column chromatography and/or mass spectrometry. The improved sample injector (4) features an arrangement to allow a pyrolytic probe (26) to be more easily inserted into the vaporization cavity (6) while permitting the sample to be volatilized in such a way that the sample is more efficiently introduced onto the column. Another feature of the invention is the use of means (28) to reduce the volume of the pyrolysis/vaporization cavity (6) so as to provide efficient throughput of pure sample. Also part of the present invention is a gas chromatograph and gas chromatograph-mass spectrometer which uses the sample injector of the present invention.
