Abstract
Apparatus for killing pests with an electrified screen. The screen has conductive weft strands woven between insulative warp strands. Insulative weft strands may be disposed between adjacent conductive weft strands. Busses are disposed in the warp having an insulative base and conductive strips on opposite sides thereof. Alternate conductive weft strands contact one of the strips and the remaining conductive weft strands contact the other strip. The screen may be mounted vertically about a field to kill insects attempting to enter. Also the screen may be employed around the home to kill pests.
Claims6
An electrical screen for killing pests comprising:
- a set of warp strands of an electrically insulating material;
- a first set of weft strands of an electrically insulating material, woven between said warp strands;
- a second set of weft strands of an electrically conducting material woven between said warp strands, each strand of said second set being separated from an adjacent strand of said second set by at least one strand of said first set;
- and
- means for applying an electrical potential between each strand of said second set and the adjacent strand of said second set.
An electrical screen for killing pests comprising:
- a set of warp strands of an electrically insulating material;
- a set of weft strands of an electrically conducting material woven between warp strands;
- at least one bus having an electrically insulating base and first and second electrically conductive strips, said base having generally planar outer surfaces, said strips being disposed on said outer surfaces on opposite sides of said base, said at least one bus being disposed parallel to said warp strands, said electrically conducting weft strands being woven about said at least one bus so that alternate ones of said electrically conducting weft strands contact the side of said first strip opposite said base and the remainder of said electrically conducting weft strands contact the side of said second strip opposite said base;
- and
- means for applying a voltage across said first and second strips.
