Abstract: A method and an apparatus for continuous real time heating value/coal flow balancing of coal from a coal feeder to a burner. The apparatus includes a Dual-energy Gamma Attenuation (DGA)/Multi-energy Gamma Attenuation (MGA) device for measuring coal quality at a specific location between the coal silo/bunker and the coal feeder in a coal fired plant in order to control the individual burner stoichiometries according to the measured coal quality. By strategically placing the DGA/MGA device, continuous accurate real-time coal quality information is accomplished for making individual adjustments in order to improve stoichiometry to optimize performance of the system.

Abstract: Methods and apparatus for continuous real-time measurement of bulk material using gamma irradiation. A multi-energy gamma attenuation device monitors bulk material flow and produces a spectrum that is compared to a baseline spectrum to produce a relative weight/impurity/component ratio. A sample analysis, in combination with measurement of the relative weight/impurity/component ratio of the sample, allows for determination of the coefficients for determining the absolute weight/impurity/component values of the bulk material.

Abstract: A fastening system and method to secure a light panel to the rear of a picture frame through the use of dual locking refittable fasteners in combination with retainers of the frame. The versatile thin illumination assembly system, consisting of the combination of the light panel and mounting system, can be applied to most existing display frames, thus converting a non-illuminated picture frame to an illuminated picture frame. The system when coupled with a frame creates an open backing that maintains the original light panel housing and eliminates heat buildup or dissipation complications often experienced with closed mounting systems. The mounting system and method requires no additional tools for the assembly process, and the resulting frame assembly is thin and easy to assemble.
