BARBED-WIRE SIGNALING BELT FOR ENGINEERING STRUCTURES Russian patent published in 2006 - IPC F41H11/08 

FIELD: special military-purpose entanglements featuring obstruction and signaling properties at a time.

SUBSTANCE: the device has a metal belt with cutting edges over the entire length, a signaling core is rolled inside it in the longitudinal direction. The signaling core is made of a current-conducting elastic material with a volume resistivity of 10³-10⁵ Ohm.cm. One or more elastic non-insulated conductors are positioned inside the core in the longitudinal direction. Porous current-conducting polyethylene is used as the current-conducting elastic material, it contains foaming polyethylene concentrate and current-conducting polyethylene filler with acetylene soot (20-40%) at a ratio of the mentioned components within 1:3 to 1:5. The gap between the edges of the rolled metal belt may be filled with an elastic sealant.

EFFECT: enhanced efficiency of the barbed-wire belt structures.
