Title: Implement convertible between a use position and a transport position
Inventor: HOUCK SHANE A
IPC: A01B73/02
Filed: 1996-02-12
Abstract: Disclosed is a hitchable and towable implement suitable for the attachment of various agricultural tooling and that is convertible between a laterally expanded use position and a laterally narrow transport position.  The implement has a wheeled lower center section connectable to a towing tractor by an elongate tongue member.  An upper center frame section rotates on the lower center section.  Powered and hinged lift arms extend in opposite directions from the upper center section and attach to a pair of wing sections for raising and lowering the wing sections. The wing sections rotate with the lift arms and the upper center section about the lower center section.  Rotation of the upper center section one quarter turn swings the wing sections between a lateral position with respect to the lower center frame section and the transport position in which the wing sections are fore and aft of the lower center section.  In the use position, lift arms and wing sections are laterally positioned and lowered to transfer weight from the center section to wheels on the wing sections.  The lower center section and wing sections each have attachment bars extending horizontally for the attachment of desired tooling.  Hydraulic cylinders can provide the power means for the lifting of the wing sections and the rotation of the upper center portion.  The raising, lowering and swinging can all be remotely controlled from a tow vehicle.

IPC: G06Q40/00
Filed: 1996-06-27
Abstract: A method for processing a file containing a financial statement in uncoded format such as a financial statement stored in an ASCII file. The starting locations of the various types of financial tables in the financial statement as indicated by their table titles are identified by grammar descriptors. When all the table titles in the file are identified, a table title is then selected for processing. Typically after the table title, there are the associated column headers for the table, and they are analyzed and determined. Following the column headers, there are lines of text that are separated into line items, where each line item is composed of a label and/or one or more numbers corresponding to the label. With these line items, the next task is to parse these line items to verify that these line items make up the table and to identify the components of the financial table. A financial table is comprised of line items, subtotals, and grand totals. By recognizing the mathematical structure of the table, the relationship between the line items, subtotals, and grand totals can be readily understood and categorized.
