Abstract: A multi-function closure is provided for a liquid containment tank. The tank has an upper wall with an inspection opening therein. The closure includes a ring attached to the upper wall and extending around the inspection opening. A pan is removably fastened to the ring, and has a bottom and side wall forming a reservoir for collection of spilled liquid. A lid is pivotally connected to the pan for movement between open and closed positions, and can be locked in the closed position. Multiple ports are formed in the bottom of the pan for filling the tank with liquid, and suctioning or pumping liquid from the tank for discharge.

Abstract: A seed cart includes first and second mating frames. The hopper is mounted on the first frame for holding seed and has an outlet to discharge the seed. A conveyor is mounted on the second frame for movement between seed loading and unloading positions. A plurality of cylinders with extendible and retractable arms control the desired position of the conveyor. A plurality of load cells are mounted on the second frame and support the first frame. The weigh scales weigh the first frame, the hopper, and the seed in the hopper, without weighing the conveyor. Therefore, an accurate amount of seed can be dispensed from the hopper via the conveyor. Wheels and a hitch tongue can be detachably mounted on the second frame to convert the cart from a stationary unit to a mobile unit.

Abstract: A bulk liquid mobile tank is provided for above ground and transportation use. The tank has flat walls with corner welds. The side walls and end walls of the tank each have at least one horizontal brake line extending horizontally to minimize deflection of the walls, reduce the bending moments, and control stress propagation through the welds. The brake lines are V-shaped.
