Abstract: The extraction of hydrocarbon fuel products such as kerogen oil and gas from a body of fixed fossil fuels such as oil shale is accomplished by applying a combination of electrical energy and critical fluids with reactants and/or catalysts down a borehole to initiate a reaction of reactants in the critical fluids with kerogen in the oil shale thereby raising the temperatures to cause kerogen oil and gas products to be extracted as a vapor, liquid or dissolved in the critical fluids. The hydrocarbon fuel products of kerogen oil or shale oil and hydrocarbon gas are removed to the ground surface by a product return line. An RF generator provides electromagnetic energy, and the critical fluids include a combination of carbon dioxide (CO2), with reactants of nitrous oxide (N2O) or oxygen (O2).

Abstract: A support system for use in partition walling and in supporting shelving and other elements. The system comprises an elongated post having a core, a face structure comprising a pair of spaced webs, each extending longitudinally of the post and delineating a longitudinally extending slot and sections joining the webs to the core and defining a space between the webs and the core. An elongated strip is a push fit within part of the space between the webs and the core, the strip having a part through which a series of longitudinally spaced locating holes are formed. The strip is shaped so that when fitted within said space said part lies behind said slot substantially parallel to the webs of the post and there is space left between said part and the core. This space may receive tabs on the ends of brackets shaped to interlock with the locating holes in the strip.
