TH2385B - Methods for killing rats and similar animals and equipment for performing this method - Google Patents

Abstract

Sufficient liquid nitrogen is poured into the openings of the cavities in the ground. In order to suffocate the field mice to death, and the poured liquid nitrogen evaporates and fills the burrows. with the evaporated nitrogen and thus the evaporated nitrogen from the channel Other openings by its expansion which made the mouse in the suffocation cavity until death This method is ineffective. It is harmful to other animals except the field rats who have used this method and done it. Provides highly effective elimination of rodents.

Claims (6)

1. The rat killing method consists of the following steps: (a) feeding sufficient quantities of liquid nitrogen into the funnel. Open one of the burrows in the ground to make the rats. Suffocation to death and (b) evaporates liquid trigen to fill the cavity with Nitrogen to evaporate and evaporate nitrogen from open channels. Other compartments by the expansion of volatile nitrogen. Which makes the mice That is in the hollow, suffocating until death 2. As mentioned in claim number one, the amount of liquid nitrogen fed is approximately 300 to approximately 500 m3 for a 30 liter cavity. 3. Equipment for killing rats consists of: a funnel, one end smaller in diameter than the other, and modified to fit into the cavity. The opening of the cavity where the vole lives For feeding nitrogen Liquid into the cavity And a way for covering the other end Of the atmosphere cone 4. Equipment as described in Clause III, the closed path, including the enclosures for enclosing the cones. Tees enclosed With opposite ends open And has a lid for closing the end Open one side of the enclosed And where inside the cone is connected to a tee Enclosed to make the cone centered within the enclosed by There is the end of the cone with a smaller diameter in Location far from the open end of the enclosed. 5. The equipment for killing rats consists of (a) the storage route for liquid nitrogen and (b) the injection route. The liquid nitrogen coming from the storage into it In the burrows where field rats live That the injection has been modified to connect with Can be stored using a bendable pipe. To obtain liquid nitrogen and as well as The throttle attached to the storage and use the control lever. Liquid nitrogen injection, a injector attached to a mandrel for obtaining liquid nitrogen, and has been modified to fit into one of the cavity openings and a flattened disc that fits perfectly around the nozzle. For covering one of the cavity. 6.The equipment mentioned in claim five, storage includes a tank for the storage of liquid nitrogen (6 Claims, 2 Pages, 2 Photos).
