Abstract: A directional hopper tee has a fluted interior vertical pipe that merges into a horizontal pipe. The vertical pipe has an opening that connects to a hopper to receive bulk material, or product, and a horizontal pipe centered upon the end of the vertical pipe. The horizontal pipe has an inlet that also receives bulk material and pressurized air from ahead of the hopper and an opposite outlet that discharges the bulk material from the hopper tee. The vertical pipe has a flange that abuts the hopper and an opening in the flange that matches the opening of a valve on the hopper itself. At the opening, the vertical pipe begins to turn towards the outlet of the lower pipe with an internal flute. The flute begins immediately at the flange resulting in a vertical pipe with a curved shape towards the outlet and a square shape towards the inlet. The present invention raises the ground clearance of the horizontal pipe by at least an inch resulting in a hopper tee that clears at least 7 inches above the ground.

Abstract: A connection device has a male connector and a female connector. The female connector will only accommodate the dedicated male connector, thereby prohibiting a misconnection with the wrong male connector. In certain embodiments, a member prohibits male connectors, other than a dedicated male connector, from being inserted into the female connector. In certain other embodiments, a post prohibits male connectors, other than a dedicated male connector including a slot, from being inserted into the female connector. In still certain other embodiments, a series of prongs in the male connector and corresponding grooves in the female connector ensure the proper connection. Once the male connector is inserted and secured within the female connector, a fluid-tight seal is formed between the male connector and the female connector.
