Abstract: A method can include combusting an expanded turbine exhaust and a first fuel within a first reformer to produce a first exhaust. A hydrocarbon can be reformed in the first reformer to produce a reformed hydrocarbon and heat can be transferred from the first exhaust to a first medium. A refrigeration unit can be powered with thermal energy from the heated first medium and can cool a second medium. Heat can be transferred from one or more oxidants to the cooled second medium to produce cooled first and second oxidants. The cooled first oxidant and a second fuel can be introduced to a gas turbine unit to produce the expanded turbine exhaust and mechanical power. The cooled second oxidant can be compressed in a compressor powered with the mechanical power and the compressed second oxidant and the reformed hydrocarbon can be introduced to a second reformer to produce a syngas.

Abstract: An apparatus for angularly positioning a shaker bed, including a discharge end, includes an air source providing pressurized air, an hydraulic tank in selective communication with the air source and containing a quantity of fluid, at least one bellow in selective fluid communication with the hydraulic tank, and a lift control assembly controlling communication of pressurized air between the air source and the hydraulic tank and controlling communication of fluid between the hydraulic tank and the at least one bellow.

Abstract: A screen system employs a resiliently mounted housing, a vibration generator mounted to the housing, a mounting frame fixed to the resiliently mounted housing and a support surface. This system receives a screen including a screen frame and pre-tensioned screen cloth. The frame includes an inwardly extending mounting flange accessible from below the screen when placed in the housing. Clips pivotally mounted relative to the mounting frame include a first rounded lever extending upwardly to selectively engage the inwardly extending mounting flange. Second levers extend downwardly to cooperate with actuators. The actuators include inflatable bodies with contacts which, upon inflation, force the clips to engage the inwardly extending mounting flanges. This engagement retains the screen on a resiliently mounted housing and is able to further tension the screen in place.

Abstract: Diesel fuel composition comprising a hydrocarbonaceous diesel fuel having a cetane number in the range from 25 to 60, a polyolefin and a polyamine wherein at least one hydrocarbon chain has at least 25 carbon atoms and is bound directly to a nitrogen atom.
