Abstract: Apparatus for calibrating a meter prover is disclosed including a chamber taking the form of a substantially perfect right circular cylinder, a piston adapted for rectilinear movement within said cylinder between a first position and a second position, means for moving the piston from its first position to its second position, and an encoder coupled to the piston for providing an output signal indicative of the movement of the piston and thus the volume of fluid displaced by that movement of the piston. The calibrating apparatus comprises an antenna electromagnetic energy to the antenna whereby electromagnetic waves are emanated into the chamber. A detector is coupled to the antenna to detect electromagnetic energy leaving the chamber and is in turn coupled to a resonant detector in the form of a cathode ray tube, whereby a minimum of the level of the electromagnetic energy may be determined. Further, a frequency detector in the form of a counter, is connected to the output of the generator to detect the frequencies of the generator output at which the minimum level occurs as observed upon the cathode ray tube corresponding to the establishment of a resonant standing wave within the chamber of the meter prover. The frequencies at which the resonant standing waves are established within the chamber, in turn determine the volumes corresponding to the first and second positions and therefore the difference in volume between the first and second positions corresponds to the displacement volume as would be drawn by the movement of the piston from its first to its second position through the fluid flow meter under test.

Abstract: Disclosed is a phased array for steering an electromagnetic wave, which includes a first layer of active material, including parallel first inner and outer surfaces, and a second layer of active material, including parallel second inner and outer surfaces which are also parallel to the first inner and outer surfaces, the second layer being adjacent to the first layer. An electrically conductive ground plane of indium tin oxide is disposed between the first and second layers and in electrical contact with the first and second inner surfaces. A first series of spaced parallel electrodes, each of the electrodes being in the form of a thin strip of indium tin oxide, is deposited on the first outer surface, while a second series of spaced parallel electrodes, each of these electrodes also being in the form of a thin strip of indium tin oxide, is similarly deposited on the second outer surface but is orthogonal to the first series of electrodes. A first anti-reflective coating may be deposited on the first outer surface, with a second antireflective coating deposited on the second outer surface.

Abstract: A method for the detection and quantitative analysis of certain selected constituent parts of a gas stream. A gas stream containing the selected constituent is introduced into a reaction zone and contacted with metastable mercury (6.sup.3 P.sub.o) atoms to form an excited complex of the selected constituent and the metastable mercury atom, which decomposes emitting light. The intensity of the light emission is measured and directly correlatable to the concentration of the constituent in the gas stream. The method of the present invention is particularly applicable to the measurement of ambient air containing selected constituents in an amount or concentration in the 1-100 ppb range. The method can be used to measure trace amounts of numerous selected constituents contained in a gaseous stream including such constituents as ammonia, hydrazine, water vapor, alcohols and various amines.

Abstract: A meter and a method are provided for measuring the composition and flow rate of a coal slurry and other similar mixtures. The meter is a waveguide through which the mixture flows. Microwaves are propagated in the waveguide from a transmitter probe. A detector probe spaced from the transmitter probe receives signals from the microwaves. Those signals are processed to determine a characteristic frequency of the waveguide or the wavelength of the propagating microwave, which are related to the composition of the mixture within the waveguide. A second transmitter and detector pair determines these properties for another portion of the waveguide. Differences in the frequencies resulting from inhomogenuities in the mixture are cross correlated to determine the flow rate of the mixture.

Abstract: Apparatus and method are disclosed for measuring the volume of a chamber of a meter prover. The meter prover includes a piston adapted for rectilinear movement within said cylinder between a first position and a second position. The volume measuring apparatus comprises an antenna disposed within the chamber and a generator coupled to apply electromagnetic energy to the antenna whereby electromagnetic waves are emanated into the chamber. A detector is coupled to the antenna to detect electromagnetic energy reflected from the chamber and is in turn coupled to a resonant detector in the form of a cathode ray tube, whereby a minimum of the level of the electromagnetic energy may be determined. Further, a frequency detector in the form of a counter, is connected to the output of the generator to detect the frequencies of the generator output at which the minimum level occurs as observed upon a display device corresponding to the establishment of a resonant standing wave within the chamber of the meter prover. The frequency(ies) at which the resonant standing waves are established within the chamber, in turn determine the volume of the meter prover chamber. The electromagnetic field(s) are generated within the chamber of a mode selected so that at a resonant condition within the chamber, the electric and magnetic component fields of the electromagnetic field have a defined relation to the dimensions of the chamber of regular geometry, illustratively, a right circular cylinder.

Abstract: A gaseous medium containing aerosols is drawn through a quartz sampling tube and a filter located therein, with the aerosols becoming entrapped on the filter. The filter is located at the geometric center of a microwave cavity, and the principal resonance of the latter is tracked with the aid of an adaptive electronic circuit. The time rate of change of the resonant frequency is a function of the rate of deposition of particulate matter on the filter, and principally of the liquid water content of those aerosols. Water in the vapor phase passes through the filter and does not affect the measurement; solid particulate does affect the frequency shift but in a second order manner and is readily compensated for after measurement of total aerosol mass deposited and the determination of the dielectric constant of the solid species therein. In a preferred embodiment a pair of microwave cavities is utilized to compare the resonant shift with the resonant frequency indicated for the same air sample after removal of the aerosol.
