Patent number: 11716993Abstract: A composition and method for killing feral hogs: a bait that is attractive to hogs is mixed with a lethal amount of sodium nitrite, along with sufficient base to inhibit decomposition of the sodium nitrite. At sufficiently high pH, encapsulation of the sodium nitrite is not required to inhibit decomposition. In the absence of substantial decomposition, the sodium nitrite itself is not aversive to the pigs, and may even enhance acceptance of the baits by the pigs. Optionally, an anti-emetic compound is added to the mixture to reduce the likelihood the bait will be vomited. Optionally, an additional toxicant such as luteolin is added to the mixture.Type: GrantFiled: August 24, 2020Date of Patent: August 8, 2023Assignee: Board of Supervisors of Louisiana State University and Agricultural and Mechanical CollegeInventors: Glen Gentry, John Pojman, Baylen Thompson

Publication number: 20130209722Abstract: A gypsum board with multiple tapered edges has a flat, rectangular main flat body with four tapered edges. The main flat body is a gypsum core sandwiched between two paper sheets. The main flat body may be of any appropriate size, including 4 feet by 4 feet or other sizes. In a method for manufacturing the gypsum board with multiple tapered edges, a quantity of gypsum slurry is fed between two continuous paper sheets with a conveyor system to make a continuous gypsum sheet and longitudinal edges of the continuous gypsum sheet are tapered. The gypsum slurry is partially dried, and then the continuous gypsum sheet is transversely compressed between an upper bracket and a lower bracket to form a transverse tapered impression. The continuous gypsum sheet is cut at the tapered impression, and the transverse tapered edges are enclosed with finishing paper.Type: ApplicationFiled: March 26, 2013Publication date: August 15, 2013Inventor: Dennis Arthur ARSENEAULT
