20090212140 | System and method for processing hygroscopic materials - The present invention is a system and method for reducing the size of a hygroscopic material while simultaneously drying the material at a relatively low temperature to a predetermined value during the reduction process. The present invention utilizes a preconditioning make-up air system to significantly dehumidify the make-up air to values in the range of 0.02 grains per pound of dry air while limiting the temperature of the make-up air exiting the preconditioning make-up air system to below a predetermined critical value. While not limited in its application to any one particular hygroscopic material, the present invention is particularly adapted to uses where the product is a temperature-sensitive, water adsorbing material such as sodium sesquicarbonate or trona ore. | 08-27-2009 |

20130091125 | CONSTRUCTION DRAWING EVALUATION SYSTEMS AND METHODS - The invention provides the ability to count symbols within drawings in an automated fashion using a computer processor. This may be accomplished by identifying a particular symbol (representing a drawing part) and then permitting the computer to search for the identified symbol in the drawing. Following the initial search, a secondary search may be performed to increase the accuracy of an initial automated count, and obtaining refined searches results representing similar parts (represented by the same symbol) but being a part type as indicated by an identifier associated with the initial symbol. | 04-11-2013 |

20090176286 | Process for Fractionating Lignocellulosic Biomass into Liquid and Solid Products - The invention herein is an efficient, flexible biomass fractionation process comprising digesting a lignocellulosic-biomass material at about 120-220° C. and a pH of less than about 4, in an aqueous mixture containing an effective concentration of at least one solvent for lignin, and separating to recover a solid phase that contains a large fraction of the cellulose originally in the starting lignocellulosic material and a liquid phase that contains most of the lignin and hemicellulose originally in the starting lignocellulosic biomass. The process can produce a solid phase that contains at least 75% cellulose and less than 10% lignin. The cellulose-rich solid product can be converted very efficiently to glucose. The solid product can also be used in commercial pulp applications, such as papermaking or fluff pulp. Hemicellulose sugars and lignin can be used directly or converted to other products. | 07-09-2009 |

20140106556 | METHOD FOR MANUFACTURING A DUAL WORK FUNCTION SEMICONDUCTOR DEVICE - A method of manufacturing a dual work function semiconductor device is disclosed. In one aspect, the method includes providing a substrate having first and second areas for forming first and second transistor types. The method additionally includes forming a dielectric layer on the substrate, which extends to cover at least parts of the first and second areas. The method additionally includes forming a first metal layer/stack on the dielectric layer in the first area, where the first metal layer/stack comprises a first work function-shifting element. The method additionally includes forming a second metal layer/stack on the first metal layer in the first area and on the dielectric layer in the second area, where the second metal layer/stack comprises a second work function-shifting element. The method additionally includes annealing to diffuse the first work function-shifting element and the second work function-shifting element into the dielectric layer, and subsequently removing the first metal layer/stack and the second metal layer/stack. The method further includes forming a third metal layer/stack in the first and second predetermined areas. | 04-17-2014 |
