Patent number: 5665910Abstract: A means of accurately measuring farm chemical during its application, through the use of load cell and a means of mounting this load cell to a sprayer apparatus is disclosed. The measurement of the chemical is accomplished by the use of a load cell which is mounted in a position below a keg of liquid farm chemical. The load cell measures the weight of the chemical keg and the liquid chemical contained therein. By knowing the specific gravity of the chemical being used and the weight of the keg itself, the operator can accurately compute the volume of chemical which has passed through the sprayer system and the rate of that passage. This gives the operator an accurate measure of the amount of the liquid chemical applied to each acre of crop land.Type: GrantFiled: July 9, 1996Date of Patent: September 9, 1997Inventors: Scott William Knutson, Curtis Jon Knutson

Patent number: 5355122Abstract: Disclosed in a Rainfall Detection and Disable Control System which provides detection and a visual display of both a trace level and a variable accumulation level of natural rainfall. The dual interacting rainfall detection system provides a unique sprinkler system control function that disables sprinkler system watering both during and after a rain shower, based upon the amount of rainfall accumulation, and user selectable disable time periods. A short variable disable time period is initiated by the trace rainfall detection probe and a long variable time period is initiated by the accumulation rainfall detection probe. The trace rainfall detection probe provides the control function of preventing watering, at the onset of, and during a rain shower. The short disable time period of the trace detection function allows the next watering cycle to occur, if no significant rainfall accumulation is detected.Type: GrantFiled: July 24, 1992Date of Patent: October 11, 1994Inventor: Gary A.

Patent number: 5174499Abstract: An irrigation system includes one or more valve assemblies which are connected in series to a pressurized source of water. Each valve assembly includes a cylindrical housing, a ball valve, an inlet and two outlets with one outlet generally opposite from the inlet in a lower portion of the housing. The other outlet is disposed in an upper portion of the housing and adapted to direct water to an area of ground for irrigation. A pit and float are associated with each valve assembly and arranged so that some of the irrigation water will flow into the pit and raise the float. The float is connected spring biasing element and a U-shaped pivotal member. This U-shaped pivotal member maintains a spring in a compressed or energy-stored condition and releases the spring biasing element when the float reaches a predetermined level so that the ball valve will spring upwardly to close the upper outlet and redirect the water to another assembly. Water pressure will then maintain the valve in that position.Type: GrantFiled: November 5, 1991Date of Patent: December 29, 1992Inventor: Saleh A. Al-Hamlan
