RAT EXTERMINATION APPARATUS Russian patent published in 1996 - IPC

FIELD: deratization equipment. SUBSTANCE: apparatus has electrodes formed as concentric cylinders defining high-frequency heating chamber, with outer cylinder making low-potential electrode. Corona electrodes are additionally positioned onto electrodes. Working run of scraper conveyor is positioned within lower part of low- potential electrode. Heating member with fan is positioned within tube permeable for electromagnetic waves. Tube is adjoining to inner high-potential electrode, where bait is placed. Rodent attracted by bait penetrates into electrode system, where corona discharge disorients animal and high-frequency radiation kills it. EFFECT: increased efficiency in rat control and enhanced reliability in operation. 2 dwg
