20110143827HELICAL BAR CONCAVE AND METHOD OF MANUFACTURING - A helical bar concave comprising a grate having helical mounting framework and helical cutouts to form a percent open area having a helical geometry. Configurable and segmented rub bars are mounted in a helical fashion to a cylindrical helical surface of the grate. A method of manufacturing a helical bar concave from a flat, rolled laser cut arrangement that provides a net helical concave functionality. Laser cutting a flat metal sheet to form helical cutouts defining a percent open area having a helical geometry in combination with configurable rub bars mounted in a helical fashion results in a configurable helical bar concave in which the number or aggressiveness of the threshing surface on the inside radius of the grate may be changed and/or the rub bars may be moved to the outside of the grate to change the percent open area and hence the separation characteristics of the concave.06-16-2011

20090017885CROP PROCESSING METHOD AND APPARATUS - In a method for processing swathed crops, the entire cut crop is picked from the field and transported to a processing facility located away from the field. The processing facility has a threshing apparatus which separates grain from the cut crop, leaving a crop residue comprising plant stalks, chaff, and other constituents of the cut crop. The separated grain is conveyed from the threshing apparatus to a grain storage bin or directly to a transport truck for delivery to a grain terminal. The processing facility also includes crop residue handling means for conveying crop residue to a bulk storage pile, to a baling machine, or to some other selected location. The method makes field baling operations unnecessary, thus expediting the total removal of the crop from the field.01-15-2009
