Abstract: A flow control device sized to fit into a pop-up sprinkler inlet reducing the cross-sectional area of the inlet thereby controlling the volume of water by restricting the flow able to pass through and inducing a pressure drop to the sprinkler head for correct droplet formation. A tapered body with spaced ridges permits the flow control device to “snap into” pop-up sprinkler inlets of different sizes. A top surface of the flow control device includes a small opening which acts as the new inlet. A cover cap and stem spring assembly of the pop-up sprinkler are removed from an installed pop-up sprinkler body revealing the inlet allowing the flow control device to be pressed downward into the inlet until one of the ridges snaps in place. The cover cap and stem spring assembly are then returned to the body completing the retrofit. A universal flow control device is also disclosed.

Abstract: A flow control device which securely fits into a gap between an irrigation riser and orifice in a sprinkler head. One version includes a threaded outer edge which mates with threads on an inner surface of the irrigation riser. Another version incorporates pliable outer edges to fill in threads on an inner surface of the irrigation riser.

Abstract: A sprinkler riser having an integral water flow restrictor. The water flow restrictor is built into the riser rather than comprising a separate apparatus configured for insertion into the riser. A two component water flow restrictor allows orifice size to be adjusted to control and adjust the quantity of water permitted to pass through the riser.

Abstract: A carry-on tote bag that can be ridden, more specifically, a baggage scooter for transporting a carrying case or luggage item, additional items, and/or a person. The baggage scooter has a first plate with a wheel or wheels and a retractable handle for holding a carrying case or luggage item, and a selectively deployable second plate with a wheels or wheels, upon which items can be carried or upon which a person can ride in a standing or other position. The baggage scooter may be used with or without a carrying case or luggage item attached. The baggage scooter may include a driving device for moving the baggage scooter. The baggage scooter may be integrally formed to a baggage item or adapted to carry baggage or other items.
