Title:
APPARATUS FOR TREATING FLOWSTREAMS BY ELECTROMAGNETIC FLUX
Document Type and Number:
WIPO Patent Application WO2000003781
Kind Code:
A8
Abstract:
In an apparatus for treating liquid with electromagnetic flux, coils (L1, L2 and L3) surround a pipe (16) and are excited by a switching circuit (72) that includes a triode switch turned on and off in response to the voltage applied to the coil (L1, L2 and L3) such that during operative half cycles current is conducted through the coils (L1, L2 and L3) initially, and then substantially before the end of each half cycle, the circuit causes an open condition during which current builds up in the coils (L1, L2 and L3). This produces a ringing current in and ringing voltage across each coil (L1, L2 and L3) and consequent ringing electromagnetic flux in the liquid passing through the pipe (16). Preferably, the fluxes produced by at least two of the coils (L1, L2 and L3) move in opposite directions through the pipe (16).
