Bioluminescence monitor and method for enzymatic determinations. [Patents]

Description: An on-line, nonreferenced apparatus for measuring the concentration of a biomarker species in authentic biological samples in solution comprises conduit means for conducting said sample solution from a source of said solution, stream diversion means disposed within the conduit for diverting a predetermined amount of said sample for analysis, means for introducing and independently regulating the flow of one or more reactants disposed in fluid communication with said diverted stream, incubating means within the diverted stream for reacting said reactants and biomarkers to produce a bioluminescence emission, and means disposed within the diverted stream for monitoring said emission intensity which is correlatable to said biomarker concentration.

Solar Retorting of Oil Shale

Description: An apparatus and method are described for retorting oil shale using solar radiation. Oil shale is introduced into a first retorting chamber having a solar focus zone. There the oil shale is exposed to solar radiation and rapidly brought to a predetermined retorting temperature. Once the shale has reached this temperature, it is removed from the solar focus zone and transferred to a second retorting chamber. In the second chamber, the oil shale is maintained at the retorting temperature, without direct exposure to solar radiation, until the retorting is complete.
