摘要： A method for demodulation of a phase shift keyed signal in which the phase shift keyed signal is converted into a plurality of successive outputs, each of which is representative of a phase and amplitude of the phase shift keyed signal over additional sets of windows and carrier phases. Each said additional set has a different offset in time and carrier phase from the other additional sets of windows and carrier phases. The carrier phase and window offsets of the phase shift keyed signal are estimated using the plurality of successive outputs. The phase shift keyed signal is then decoded back into digital data using the estimates.

摘要： A method for planning continuity logging surveys and for detecting the presence of a continuous or discontinuous low-velocity inclusion in a subterranean geological formation. To detect the presence of a continuous or discontinuous low-velocity inclusion, a seismic source is inserted into a source borehole located at either a boundary or a center of a low velocity inclusion. Seismic energy is generated coupled to the low-velocity inclusion using the seismic source. The seismic energy propagates as seismic waves through the low-velocity inclusion and is measured and recorded by at least one detector disposed in a receiver borehole. The seismic waves are analyzed for the presence of at least one seismic signature from which the distance of a discontinuity, if any, of the low-velocity inclusion with respect to the receiver borehole can be determined.

摘要： A method and apparatus for controlling a fluid distribution regulator disposed in a fluid distribution system in which an intelligent controller is operatively connected to at least one fluid district regulator for controlling the district regulator. At least one intelligent low-pressure monitor is connected to the distribution system at a distance from the fluid district regulator and monitors ambient temperature and fluid pressure in the distribution system. A computer is operatively connected to the intelligent controller and the intelligent monitor and provides status checks and manual overrides of the intelligent controller and the intelligent monitor. An adaptive algorithm proximate the intelligent controller generates a prediction of fluid demand and a corresponding district regulator fluid outlet pressure setting based upon feedback from the intelligent monitor.

摘要： A method for detection of a disturbance in a waveguide comprising transmitting a wavefield having symmetric and antisymmetric components from a horizontally and/or vertically polarized source and/or pressure source disposed symmetrically with respect to the longitudinal central axis of the waveguide at one end of the waveguide, recording the horizontal and/or vertical component or a pressure of the wavefield with a vertical array of receivers disposed at the opposite end of the waveguide, separating the wavenumber transform of the wavefield into the symmetric and antisymmetric components, integrating the symmetric and antisymmetric components over a broad frequency range, and comparing the magnitude of the symmetric components and the antisymmetric components to an expected magnitude for the symmetric components and the antisymmetric components for a waveguide of uniform thickness and properties thereby determining whether or not a disturbance is present inside the waveguide.

摘要： A pilot burner apparatus for use with gas-fired appliances, such as gas-fired water heaters, is provided with a structure configured for the early detection, and response to, the presence of flammable vapor in the atmosphere ambient to the appliance. Combustion air for the pilot burner is taken from that region of the ambient atmosphere, most likely to become contaminated with flammable vapor first. One or more flame characteristics of the pilot burner flame are monitored, and if the flame characteristics depart from a predetermined range of parameters, gas flow to the pilot and main burner(s) of the appliance are cut off. The sensitivity of the pilot burner is such that flammable vapors are detected before the concentration of flammable vapors car rise to the lower flammability limit of the anticipated flammable vapor(s).

摘要： The instant invention relates to a method and apparatus to determine the thermodynamic properties of a gas medium without making a determination of gas composition. In the instant invention, the speed of sound of a gas medium in a vessel is determined at various temperatures and pressures based upon an isobaric process with estimated initial values of density, compressibility and numerical deriviative (dZ/dT) for the same gas medium. According to the preferred embodiment, this information may be measured at constant pressure or constant temperature. Once the physical information is determined, a routine is executed by which initial estimated parameters such as the compressibility and heat capacity of the gas medium will converge to accurate values. From these parameters, the thermophysical properties of the gas medium may be determined.

摘要： An ultrasonic scan assembly is adapted to efficiently and accurately scan a surface and cross-section of a wall of an underground gas pipe with ultrasonic energy transmitted and received by an ultrasonic transducer provided therein. The input pulse applied to the ultrasonic transducer is calibrated so that its width matches the natural mechanical resonant frequency of the ultrasonic transducer. As a result, the energy efficiency of the transducer is maximized and the accuracy of the scan is improved.

摘要： A process for the recovery of sulfur and carbon monoxide from metal sulfates in which the carbon monoxide is recycled as a reducing agent for reaction with the metal sulfate. Metal sulfates such as gypsum (calcium sulfate dihydrate) are processed to form sulfur dioxide. The sulfur dioxide is contacted with carbonaceous matter at sufficiently high temperature to form elemental sulfur and carbon monoxide. The carbon monoxide is then recycled for use as a reducing agent in the initial processing of the metal sulfate.
