Show moreA heterodyning interferometric monitoring apparatus for simultaneously measuring in situ and in real time the optical and physical thicknesses of a sample during a deposition process. A linearly polarized monochromatic light beam is passed through a frequency shifter which produces therefrom a dichromatic light beam having two orthogonally linearly polarized components at respective different frequencies. The dichromatic beam is applied to a modified Twyman-Greene interferometer, from which two heterodyne light beams emerge. The first of the two light beams is a combination of light at the first frequency reflected from the sample and light at the second frequency reflected from a reference plate, from which the physical thickness of the sample can be determined using a heterodyne signal detector. The second light beam is a combination of light at the first frequency passed through the sample and light at the second frequency passed through the reference plate, from which the optical thickness of the sample can be determined using another heterodyne signal detector.

Show moreA method and system for detecting environmental contamination, such as subsurface contamination, include a test probe located in a medium. The probe is adapted to collect a fluid sample from the medium for determining the presence of a contaminant having a vapor pressure. Pneumatic communication lines extend from a test point and connect to the probe. A detector/analyzer is connected to the distal end of the communication lines of the probe. While connected, a fluid sample is taken into the probe and transported in the pneumatic communication lines by a carrier gas to the detector/analyzer for analysis of the contaminant. The general principle is applicable for contaminant detection and/or analysis in soil masses, liquid masses and gases.

Show moreThe effects of radio frequency electric field peaking in the earth formations surrounding a conductor excited by radio frequency energy in the controlled in situ heat processing of hydrocarbonaceous earth formations are mitigated by providing an inert buffer region around the conductor to which radio frequency electromagnetic energy is supplied to produce an electric field within the earth formations. A portion of the earth formations is removed to accommodate insertion of the conductor at a desired location in the earth formations and to provide a buffer region between the conductor and the surrounding earth formations. The conductor is supported at the desired location in spaced relationship to the surrounding earth formations, the buffer region encompassing the principal region of the electric field enhancement region around the conductor where the probability of breakdown in the earth formations over the period of application of the radio frequency energy would be above a tolerable level. The buffer region is filled with dielectric material having an electric field breakdown level greater than that of the surrounding earth formation medium such that the probability of breakdown in the buffer region over the period of application of the radio frequency energy is tolerable. Preferably the filler medium has a power dissipation characteristic less than that of the surrounding earth formations.

Show moreA subharmonic noise reduction circuit having an input terminal and an output terminal. The circuit has a first differential amplifier with a first non-inverting input, a first inverting input and a first output. The overall circuit input terminal is connected to the first non-inverting input. A low-pass filter is connected between the first output and the first inverting input. A second differential amplifier has a second non-inverting input, a second inverting input and a second output. The second output is connected to the overall circuit output terminal. A first resistor is connected between the second output and the second inverting input. A second resistor is connected between the first non-inverting input and the second non-inverting input. The circuit operates at unity gain of the DC voltage component and thus the DC output voltage follows the DC input voltage.

Show moreA method and apparatus for electrostatic spray deposition (ESD) for fabricating a thin-layer yttria-stabilized zirconia (YSZ) electrolyte on a solid oxide fuel cell (SOFC) anode substrate constructed of nickel-YSZ cermet. By reducing the thickness of the electrolyte, and thereby reducing the cell internal IR drop, an intermediate temperature SOFC (ITSOFC) can operate at 600-800.degree. C. A collar positioned at a distance from a discharge end of a spray nozzle enhances a spray pattern of a precursor including the electrolyte material and thus provides a very thin electrolyte layer.
