Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates in general to computer controlled accounting and record keeping for grain transactions and in particular to an automatic system. 
     2. Description of the Prior Art 
     In the handling of grain buying and selling in grain elevators, it has previously been necessary for the elevator operator to weigh and sample the incoming grain, unload the grain and then weigh the vehicle to obtain the tare weight and then to calculate for each individual customer transaction the buy-sell or storage information. Each customer transaction has required the preparation of a weigh ticket and the subsequent calculations which are required to maintain and record the customer&#39;s debit or credit position as well as to obtain the overall elevator&#39;s position and inventory. 
     Such systems have been subject to human error in entering the required data, have been time consuming and required skillful personnel in obtaining accurate records. 
     SUMMARY OF THE INVENTION 
     The present invention comprises a computer controlled system for grain elevators which can receive inputs from scales and moisture meters and wherein the elevator operator can simply and easily enter with the computer keyboard the required information and the computer system will automatically record the transaction and will provide an output such as one or more printed copies to record the transaction. The system can automatically calculate purchase and sales prices including dockage discounts and allows the call-up at any time of sub-totals and can print current totals by bushels or cwt in all customer delivery options, dealer shipments and can even accumulate average moisture intake and moisture dockage revenue. 
     The system prints a daily journal listing each transaction of the day in sequential customer order and groups or transactions for a particular customer when there have been multiple transactions by one customer. 
     The system stores and maintains all incompleted transactions until the data for completing the transaction has been entered and the transaction has been printed and is no longer required to be retained in storage. 
     The system is capable of being connected to an electronic weigh scale. It can be connected to a permanent memory storage system and can be connected to terminal hardware. 
     The system completes every grain transaction in or out from weight scale to accounting faster and accurately and eliminates human error. Instant marketing and decision data is available with the invention.

     A program for the computer of this invention is attached herewith. 
     The invention comprises a definite purpose computer designed specifically for daily operating procedures of a commercial grain facility and results in increased operating and management efficiency and virtually eliminates clerical errors and substantially reduces the time and personnel needs through improved daily record keeping. 
     The invention provides information for each customer, each transaction, the delivery options and also designates share splits where more than one person is to be compensated for the grain. Such services as trucking and storage charges are also incorporated into the calculations. 
     At any time, the invention will print a &#34;daily journal&#34; of all transactions during that day or time period. Also, it is capable of printing individual settlement sheets, dealers current position reports and dealers daily position reports. 
     The invention systems perform the arithmetic calculations for automatically computing gross and tare weights to net weight considering shrinkage factors, dockages for moisture, foreign material, damage and test weight. Customer transactions may be immediately printed or retained in the computer&#39;s memory for a later printing. 
     Summaries of the current inputs and outputs of each commodity by delivery option and dealer shipments is also available for print-out. 
     The invention provides total flexibility for programming prices and dockages at any time and market fluctuations allow the operator to decrease or increase the prices immediately. 
     In order to energize the invention, a secret code number can be provided where upon the machine may be turned on or off by utilizing such secret codes for turning on or off the machine. This prevents tampering with the information stored in the computer memories during off hours by unauthorized personnel. 
     The invention can store in its memories a large number of customer transactions which can be recalled at any time for a printed customer sheet. 
     For example, for each customer transaction, the customer&#39;s number is entered on the keyboard of the machine and then the applicable commodity is identified by pressing the commodity key such as corn, beans, oats, rice, wheat, milo or sun flowers. Then the customer&#39;s delivery option such as sell, store, contracts or delayed price is selected by actuating the keyboard. The weight in, gross is automatically entered into the computer system or in an alternative mode may be manually entered from the keyboard. The moisture content of the grain is either detected and automatically supplied by the moisture meter of the invention or can be manually entered in an alternate mode. Test weight is entered and the percentage of foreign material is entered on the keyboard as well as the percent of estimated damage. When the vehicle has been unloaded the tare weight out is supplied to the computer and the invention will print a customer transaction. If the price has been established, it will be a completed customer transaction, but if delayed price or other arrangements have been made, an incomplete customer transaction will be stored for later completion. Such customer transactions may be recalled by either the customer number and specific load number or, alternatively, by the dealer transaction number. 
     The following is an example of a customer transaction print-out.
