  • USE OF TETRAMIC ACID DERIVATIVES FOR INSECT CONTROL
    Publication number: 20090298903
    Abstract: An improved miniature portable child's training toilet comprises a first chamber with a toilet seat opening, a second chamber connected thereto, and a flap member at a connection point. A miniaturized tank portion with valve means and means of selectively causing the valve to open, allows fluid from the tank to move under gravity to the first chamber and continue into the second chamber, flushing material into the second chamber of the toilet. A means of separating the first and second chambers of the toilet for emptying the second chamber after flushing comprises a gasket for sealing the junction of the chambers. An electronic sound and light producing means plays congratulatory sounds and causes the toilet to illuminate when flushed. An alternate embodiment further comprises an “S” bend connecting the chambers, forming a water trap, and causing siphon action when the toilet is flushed.
