    Abstract: The invention relates to microorganisms which normally do not ferment pentose sugar and which are genetically altered to ferment pentose sugar to produce ethanol, and fermentation processes utilizing the same. Examples include Zymomonas mobilis which has been transformed with combinations of E. coli genes for xylose isomerase, xylulokinase, transaldolase, transketolase, L-arabinose isomerase, L-ribulokinase, and L-ribulose 5-phosphate 4-epimerase. Expression of the added genes are under the control of Zymomonas mobilis promoters. These newly created microorganisms are useful for fermenting pentoses and glucose, produced by hydrolysis of hemicellulose and cellulose, to produce ethanol.

    Abstract: Active heterodimers are described which are prepared by connecting molecules of beta-glucosidase and cellobiohydrolase with a bifunctional reagent (i.e., a crosslinking agent) or by genetic fusion of the two polypeptide chains. The ability of the beta-glucosidase to catalyze hydrolysis of cellobiose to glucose, and the ability of cellobiohydrolase to bind to crystalline cellulose and to catalyze the cleavage of cellobiosyl residues from the non-reducing ends of the cellulose chains, are all retained in the combined molecule.

    Abstract: A method is described for producing silicon carbide particles using a silicon source material and a hydrocarbon. The method is efficient and is characterized by high yield. Finely divided silicon source material is contacted with hydrocarbon at a temperature of 400 DEG to 1000 DEG C where the hydrocarbon pyrolyzes and coats the particles with carbon. The particles are then heated to 1100 DEG C to 1600 DEG C to cause a reaction between the ingredients to form silicon carbide of very small particle size. No grinding of silicon carbide is required to obtain small particles. The method may be carried out as a batch process or as a continuous process.

    Abstract: A jet excitation system (10) includes a pulsator mechanism (20) positioned in a fluid delivery duct (12) upstream from a nozzle. The pulsator mechanism (20) imparts periodic pressure pulsations to a fluid stream in a manner than enhances spreading and increases entrainment and mixing of the jet (60) exiting the nozzle. The jet excitation system (10) when employed in heating, ventilation and air condition (HVAC) systems increases the entrainment, mixing and spreading of an air stream exiting a nozzle into an enclosure.

    Abstract: A method for charging a sample of either a permanent or reversible getter material with a high concentration of hydrogen while maintaining a base pressure below 10-4 torr at room temperature involves placing the sample of hydrogen getter material (11), overcharging the sample of getter material through conventional charging techniques to a high concentration of hydrogen (12), and then subjecting the sample of getter material to a low temperature vacuum bake-out process (14). Application of the method results in a reversible hydrogen getter which is highly charged to maximum capacities of hydrogen and which concurrently exhibits minimum hydrogen vapor pressures at room temperatures.
