The method and apparatus of the invention permit in situ determinations to be made of the temperature and optical constants of a substrate surface that is being treated, by measurements of radiance, reflectance and transmittance. These determinations in turn provide, at any given instant during processing, compositional and other information, thereby affording highly effective feedback control of the processing conditions. The apparatus comprises an integrated, small and relatively inexpensive instrument for process monitoring.

Method and apparatus for monitoring layer processing

An aerodynamically cleaned heat-exchanger is used in heating apparatus in which the radiant energy of a dirty fuel, such as coal or char, is efficiently recovered while the exposed heat-exchange components are protected from the deleterious combustion products.

Coal-fired heating apparatus and method

A corrective factor is applied so as to remove anomalous features from the signal generated by a photoconductive detector, and to thereby render the output signal highly linear with respect to the energy of incident, time-varying radiation. The corrective factor may be applied through the use of either digital electronic data processing means or analog circuitry, or through a combination of those effects.

Method and system for photoconductive detector signal correction

An optical technique for determining surface temperature utilizes the Christiansen effect that is exhibited by dielectric materials; i.e., strong absorption bands at certain wavenumber values, causing the radiance of the material to be that which would characterize a theoretical black body at that wavenumber value.
