Abstract: A corrugated cardboard pest repellent system for repelling and/or exterminating various pests around, within, or between layers of a corrugated cardboard construct while reducing the risk of contamination of goods or exposure by handlers. The corrugated cardboard pest repellent system generally includes one or more liners secured by an adhesive to one or more layers of a corrugated medium that has been treated by a pest repellent. The pest repellent is positioned on the underside of each crest of the one or more layers of the corrugated medium to prevent incursion of pests into the corrugated medium. Multiple layers may be stacked to form various constructs including a single face corrugated cardboard construct, a single wall corrugated cardboard construct, a double wall corrugated cardboard construct, and a triple wall corrugated cardboard construct. The resulting constructs may be utilized for various purposes, including forming various types of containers, padding, or liners.

Abstract: A limitation device which limits post-adjustment rotation of an adjustment screw (10) on single adjustment screw carburetors (20). In one embodiment, the limitation device uses a limiter cap (100, 200) removably attached to the adjustment screw (10) which works in conjunction with a limiter stop (300, 400) attached to the carburetor. In a second embodiment, the limitation device uses a limiter cap (700) removably attached to the adjustment screw (10) which works in conjunction with a plate (600) attached to the carburetor. In either embodiment, the limiter cap (100, 200, 700) presents a first and second rotational stop (110, 210) which cooperates with at least one rotational stop (304, 306, 404, 406, 606) on the limiter stop (300, 400) or plate (600). A special tool and method is also disclosed for installing and removing the device from the carburetor.
